+commit 12731158c75c8760a8bea06350eeb3e763fe1a07

+Date:   Thu Oct 11 10:29:29 2018 +1100
+
+    supply callback to PEM_read_bio_PrivateKey
+    
+    OpenSSL 1.1.0i has changed the behaviour of their PEM APIs,
+    so that empty passphrases are interpreted differently. This
+    probabalistically breaks loading some keys, because the PEM format
+    is terrible and doesn't include a proper MAC.
+    
+    Avoid this by providing a basic callback to avoid passing empty
+    passphrases to OpenSSL in cases where one is required.
+

+    upstream: Add sshd_config CASignatureAlgorithms option to allow
+    
+    control over which signature algorithms a CA may use when signing
+    certificates. In particular, this allows a sshd to ban certificates signed
+    with RSA/SHA1.

+    configure: work around GCC shortcoming on Cygwin
+    
+    Cygwin's latest 7.x GCC allows to specify -mfunction-return=thunk
+    as well as -mindirect-branch=thunk on the command line, albeit
+    producing invalid code, leading to an error at link stage.
+    
+    The check in configure.ac only checks if the option is present,
+    but not if it produces valid code.
+    
+    This patch fixes it by special-casing Cygwin.  Another solution
+    may be to change these to linker checks.

+    signature work - returns ability to add/remove/specify algorithms by
+    wildcard.
+    
+    Algorithm lists are now fully expanded when the server/client configs
+    are finalised, so errors are reported early and the config dumps
+    (e.g. "ssh -G ...") now list the actual algorithms selected.
+    
+    Clarify that, while wildcards are accepted in algorithm lists, they
+    aren't full pattern-lists that support negation.

+
+    upstream: Improve strictness and control over RSA-SHA2 signature
+    
+    In ssh, when an agent fails to return a RSA-SHA2 signature when
+    requested and falls back to RSA-SHA1 instead, retry the signature to
+    ensure that the public key algorithm sent in the SSH_MSG_USERAUTH
+    matches the one in the signature itself.
+    
+    In sshd, strictly enforce that the public key algorithm sent in the
+    SSH_MSG_USERAUTH message matches what appears in the signature.
+    
+    Make the sshd_config PubkeyAcceptedKeyTypes and
+    HostbasedAcceptedKeyTypes options control accepted signature algorithms
+    (previously they selected supported key types). This allows these
+    options to ban RSA-SHA1 in favour of RSA-SHA2.
+    
+    Add new signature algorithms "rsa-sha2-256-cert-v01@openssh.com" and
+    "rsa-sha2-512-cert-v01@openssh.com" to force use of RSA-SHA2 signatures
+    with certificate keys.

+
+    upstream: Update default IPQoS in ssh(1), sshd(8) to DSCP AF21 for
+    
+    interactive and CS1 for bulk
+    
+    AF21 was selected as this is the highest priority within the low-latency
+    service class (and it is higher than what we have today). SSH is elastic
+    and time-sensitive data, where a user is waiting for a response via the
+    network in order to continue with a task at hand. As such, these flows
+    should be considered foreground traffic, with delays or drops to such
+    traffic directly impacting user-productivity.
+    
+    For bulk SSH traffic, the CS1 "Lower Effort" marker was chosen to enable
+    networks implementing a scavanger/lower-than-best effort class to
+    discriminate scp(1) below normal activities, such as web surfing. In
+    general this type of bulk SSH traffic is a background activity.
+    
+    An advantage of using "AF21" for interactive SSH and "CS1" for bulk SSH
+    is that they are recognisable values on all common platforms (IANA
+    https://www.iana.org/assignments/dscp-registry/dscp-registry.xml), and
+    for AF21 specifically a definition of the intended behavior exists
+    https://tools.ietf.org/html/rfc4594#section-4.7 in addition to the definition
+    of the Assured Forwarding PHB group https://tools.ietf.org/html/rfc2597, and
+    for CS1 (Lower Effort) there is https://tools.ietf.org/html/rfc3662
+    
+    The first three bits of "AF21" map to the equivalent IEEEE 802.1D PCP, IEEE
+    802.11e, MPLS EXP/CoS and IP Precedence value of 2 (also known as "Immediate",
+    or "AC_BE"), and CS1's first 3 bits map to IEEEE 802.1D PCP, IEEE 802.11e,
+    MPLS/CoS and IP Precedence value 1 ("Background" or "AC_BK").

+    Disable native strndup and strnlen on AIX.
+    
+    On at least some revisions of AIX, strndup returns unterminated strings
+    under some conditions, apparently because strnlen returns incorrect
+    values in those cases.  Disable both on AIX and use the replacements
+    from openbsd-compat.  Fixes problem with ECDSA keys there, ok djm.

+    configure.ac: properly set seccomp_audit_arch for MIPS64
+    
+    Currently seccomp_audit_arch is set to AUDIT_ARCH_MIPS64 or
+    AUDIT_ARCH_MIPSEL64 (depending on the endinness) when openssh is built
+    for MIPS64. However, that's only valid for n64 ABI. The right macros for
+    n32 ABI defined in seccomp.h are AUDIT_ARCH_MIPS64N32 and
+    AUDIT_ARCH_MIPSEL64N32, for big and little endian respectively.
+    
+    Because of that an sshd built for MIPS64 n32 rejects connection attempts
+    and the output of strace reveals that the problem is related to seccomp
+    audit:
+    
+    [pid   194] prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER, {len=57,
+    filter=0x555d5da0}) = 0
+    [pid   194] write(7, "\0\0\0]\0\0\0\5\0\0\0Ulist_hostkey_types: "..., 97) = ?
+    [pid   193] <... poll resumed> )        = 2 ([{fd=5, revents=POLLIN|POLLHUP},
+    {fd=6, revents=POLLHUP}])
+    [pid   194] +++ killed by SIGSYS +++
+    
+    This patch fixes that problem by setting the right value to

+    Include includes.h for HAVE_GETPAGESIZE.

+    The configure script checks for getpagesize() and sets HAVE_GETPAGESIZE in
+    config.h, but bsd-getpagesize.c forgot to include includes.h (which
+    indirectly includes config.h) so the checks always fails, causing linker

+Author: Damien Miller <djm@mindrot.org>
+Date:   Tue Oct 31 00:46:29 2017 +1100
+
+    Switch upstream git repository.
+    
+    Previously portable OpenSSH has synced against a conversion of OpenBSD's
+    CVS repository made using the git cvsimport tool, but this has become
+    increasingly unreliable.
+    
+    As of this commit, portable OpenSSH now tracks a conversion of the
+    OpenBSD CVS upstream made using the excellent cvs2gitdump tool from
+    YASUOKA Masahiko: https://github.com/yasuoka/cvs2gitdump
+    
+    cvs2gitdump is considerably more reliable than gitcvsimport and the old
+    version of cvsps that it uses under the hood, and is the same tool used
+    to export the entire OpenBSD repository to git (so we know it can cope
+    with future growth).
+    
+    These new conversions are mirrored at github, so interested parties can
+    match portable OpenSSH commits to their upstream counterparts.
+    
+    https://github.com/djmdjm/openbsd-openssh-src
+    https://github.com/djmdjm/openbsd-openssh-regress
+    
+    An unfortunate side effect of switching upstreams is that we must have
+    a flag day, across which the upstream commit IDs will be inconsistent.
+    The old commit IDs are recorded with the tags "Upstream-ID" for main
+    directory commits and "Upstream-Regress-ID" for regress commits.
+    
+    To make it clear that the commit IDs do not refer to the same
+    things, the new repository will instead use "OpenBSD-ID" and
+    "OpenBSD-Regress-ID" tags instead.
+    
+    Apart from being a longwinded explanation of what is going on, this
+    commit message also serves to synchronise our tools with the state of
+    the tree, which happens to be:
+    
+    OpenBSD-ID: 9c43a9968c7929613284ea18e9fb92e4e2a8e4c1

+    
+    Expose devices allocated for tun/tap forwarding.
+    
+    At the client, the device may be obtained from a new %T expansion
+    for LocalCommand.
+    
+    At the server, the allocated devices will be listed in a
+    SSH_TUNNEL variable exposed to the environment of any user sessions
+    started after the tunnel forwarding was established.

+    Add 'reverse' dynamic forwarding which combines dynamic
+    forwarding (-D) with remote forwarding (-R) where the remote-forwarded port
+    expects SOCKS-requests.
+    
+    The SSH server code is unchanged and the parsing happens at the SSH
+    clients side. Thus the full SOCKS-request is sent over the forwarded
+    channel and the client parses c->output. Parsing happens in
+    channel_before_prepare_select(), _before_ the select bitmask is
+    computed in the pre[] handlers, but after network input processing
+    in the post[] handlers.

+    Make remote channel ID a u_int

+    Previously we tracked the remote channel IDs in an int, but this is

+    in-principle stopping a SSH implementation from sending, say, 0xffff0000.

+    refactor channels.c
+    
+    Move static state to a "struct ssh_channels" that is allocated at

+    
+    Explicitly pass "struct ssh" to all channels functions.
+    
+    Replace use of the legacy packet APIs in channels.c.
+    
+    Rework sshd_config PermitOpen handling: previously the configuration
+    parser would call directly into the channels layer. After the refactor
+    this is not possible, as the channels structures are allocated at
+    connection time and aren't available when the configuration is parsed.
+    The server config parser now tracks PermitOpen itself and explicitly
+    configures the channels code later.

+
+    Give configure ability to set CFLAGS/LDFLAGS later
+    
+    Some CFLAGS/LDFLAGS may disrupt the configure script's operation,
+    in particular santization and fuzzer options that break assumptions
+    about memory and file descriptor dispositions.
+    
+    This adds two flags to configure --with-cflags-after and
+    --with-ldflags-after that allow specifying additional compiler and
+    linker options that are added to the resultant Makefiles but not
+    used in the configure run itself.
+    
+    E.g.
+    
+    env CC=clang-3.9 ./configure \
+      --with-cflags-after=-fsantize=address \
+      --with-ldflags-after="-g -fsanitize=address"

+
+    upstream commit
+    
+    Expand ssh_config's StrictModes option with two new
+    settings:
+    
+    StrictModes=accept-new will automatically accept hitherto-unseen keys
+    but will refuse connections for changed or invalid hostkeys.
+    
+    StrictModes=off is the same as StrictModes=no
+    
+    Motivation:
+    
+    StrictModes=no combines two behaviours for host key processing:
+    automatically learning new hostkeys and continuing to connect to hosts
+    with invalid/changed hostkeys. The latter behaviour is quite dangerous
+    since it removes most of the protections the SSH protocol is supposed to
+    provide.
+    
+    Quite a few users want to automatically learn hostkeys however, so
+    this makes that feature available with less danger.
+    
+    At some point in the future, StrictModes=no will change to be a synonym
+    for accept-new, with its current behaviour remaining available via
+    StrictModes=off.

+    Now that we no longer support SSHv1, replace the contents
+    of this file with a pointer to
+    https://tools.ietf.org/html/draft-miller-ssh-agent-00 It's better edited,
+    doesn't need to document stuff we no longer implement and does document stuff
+    that we do implement (RSA SHA256/512 signature flags)

+commit 8b0eee148f7cf8b248c30d1bae57300f2cc5aafd

+
+    Deny socketcall in seccomp filter on ppc64le.
+    
+    OpenSSL is using socket() calls (in FIPS mode) when handling ECDSA keys
+    in privsep child. The socket() syscall is already denied in the seccomp
+    filter, but in ppc64le kernel, it is implemented using socketcall()
+    syscall, which is not denied yet (only SYS_SHUTDOWN is allowed) and
+    therefore fails hard.
+    
+    Patch from jjelen at redhat.com.

+
+    Fix weakness in seccomp-bpf sandbox arg inspection
+    
+    Syscall arguments are passed via an array of 64-bit values in struct
+    seccomp_data, but we were only inspecting the bottom 32 bits and not
+    even those correctly for BE systems.
+    
+    Fortunately, the only case argument inspection was used was in the
+    socketcall filtering so using this for sandbox escape seems
+    impossible.

+    Force Turkish locales back to C/POSIX; bz#2643
+    
+    Turkish locales are unique in their handling of the letters 'i' and
+    'I' (yes, they are different letters) and OpenSSH isn't remotely
+    prepared to deal with that. For now, the best we can do is to force
+    OpenSSH to use the C/POSIX locale and try to preserve the UTF-8
+    encoding if possible.

+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+MODULI(5)                     File Formats Manual                    MODULI(5)
+
+NAME
+     moduli M-bM-^@M-^S Diffie-Hellman moduli
+
+DESCRIPTION
+     The /etc/moduli file contains prime numbers and generators for use by
+     sshd(8) in the Diffie-Hellman Group Exchange key exchange method.
+
+     New moduli may be generated with ssh-keygen(1) using a two-step process.
+     An initial candidate generation pass, using ssh-keygen -G, calculates
+     numbers that are likely to be useful.  A second primality testing pass,
+     using ssh-keygen -T, provides a high degree of assurance that the numbers
+     are prime and are safe for use in Diffie-Hellman operations by sshd(8).
+     This moduli format is used as the output from each pass.
+
+     The file consists of newline-separated records, one per modulus,
+     containing seven space-separated fields.  These fields are as follows:
+
+           timestamp    The time that the modulus was last processed as
+                        YYYYMMDDHHMMSS.
+
+           type         Decimal number specifying the internal structure of
+                        the prime modulus.  Supported types are:
+
+                        0     Unknown, not tested.
+                        2     "Safe" prime; (p-1)/2 is also prime.
+                        4     Sophie Germain; 2p+1 is also prime.
+
+                        Moduli candidates initially produced by ssh-keygen(1)
+                        are Sophie Germain primes (type 4).  Further primality
+                        testing with ssh-keygen(1) produces safe prime moduli
+                        (type 2) that are ready for use in sshd(8).  Other
+                        types are not used by OpenSSH.
+
+           tests        Decimal number indicating the type of primality tests
+                        that the number has been subjected to represented as a
+                        bitmask of the following values:
+
+                        0x00  Not tested.
+                        0x01  Composite number M-bM-^@M-^S not prime.
+                        0x02  Sieve of Eratosthenes.
+                        0x04  Probabilistic Miller-Rabin primality tests.
+
+                        The ssh-keygen(1) moduli candidate generation uses the
+                        Sieve of Eratosthenes (flag 0x02).  Subsequent
+                        ssh-keygen(1) primality tests are Miller-Rabin tests
+                        (flag 0x04).
+
+           trials       Decimal number indicating the number of primality
+                        trials that have been performed on the modulus.
+
+           size         Decimal number indicating the size of the prime in
+                        bits.
+
+           generator    The recommended generator for use with this modulus
+                        (hexadecimal).
+
+           modulus      The modulus itself in hexadecimal.
+
+     When performing Diffie-Hellman Group Exchange, sshd(8) first estimates
+     the size of the modulus required to produce enough Diffie-Hellman output
+     to sufficiently key the selected symmetric cipher.  sshd(8) then randomly
+     selects a modulus from /etc/moduli that best meets the size requirement.

+SCP(1)                      General Commands Manual                     SCP(1)
+
+NAME
+     scp M-bM-^@M-^S secure copy (remote file copy program)
+
+SYNOPSIS
+     scp [-346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
+         [-l limit] [-o ssh_option] [-P port] [-S program] source ... target
+
+DESCRIPTION
+     scp copies files between hosts on a network.  It uses ssh(1) for data
+     transfer, and uses the same authentication and provides the same security
+     as ssh(1).  scp will ask for passwords or passphrases if they are needed
+     for authentication.
+
+     The source and target may be specified as a local pathname, a remote host
+     with optional path in the form [user@]host:[path], or a URI in the form
+     scp://[user@]host[:port][/path].  Local file names can be made explicit
+     using absolute or relative pathnames to avoid scp treating file names
+     containing M-bM-^@M-^X:M-bM-^@M-^Y as host specifiers.
+
+     When copying between two remote hosts, if the URI format is used, a port
+     may only be specified on the target if the -3 option is used.
+
+     The options are as follows:
+
+     -3      Copies between two remote hosts are transferred through the local
+             host.  Without this option the data is copied directly between
+             the two remote hosts.  Note that this option disables the
+             progress meter.
+
+     -4      Forces scp to use IPv4 addresses only.
+
+     -6      Forces scp to use IPv6 addresses only.
+
+     -B      Selects batch mode (prevents asking for passwords or
+             passphrases).
+
+     -C      Compression enable.  Passes the -C flag to ssh(1) to enable
+             compression.
+
+     -c cipher
+             Selects the cipher to use for encrypting the data transfer.  This
+             option is directly passed to ssh(1).
+
+     -F ssh_config
+             Specifies an alternative per-user configuration file for ssh.
+             This option is directly passed to ssh(1).
+
+     -i identity_file
+             Selects the file from which the identity (private key) for public
+             key authentication is read.  This option is directly passed to
+             ssh(1).
+
+     -l limit
+             Limits the used bandwidth, specified in Kbit/s.
+
+     -o ssh_option
+             Can be used to pass options to ssh in the format used in
+             ssh_config(5).  This is useful for specifying options for which
+             there is no separate scp command-line flag.  For full details of
+             the options listed below, and their possible values, see
+             ssh_config(5).

+
+     -P port
+             Specifies the port to connect to on the remote host.  Note that
+             this option is written with a capital M-bM-^@M-^XPM-bM-^@M-^Y, because -p is already

+SFTP-SERVER(8)              System Manager's Manual             SFTP-SERVER(8)
+
+NAME
+     sftp-server M-bM-^@M-^S SFTP server subsystem
+
+SYNOPSIS
+     sftp-server [-ehR] [-d start_directory] [-f log_facility] [-l log_level]
+                 [-P blacklisted_requests] [-p whitelisted_requests]
+                 [-u umask]
+     sftp-server -Q protocol_feature
+
+DESCRIPTION
+     sftp-server is a program that speaks the server side of SFTP protocol to
+     stdout and expects client requests from stdin.  sftp-server is not
+     intended to be called directly, but from sshd(8) using the Subsystem
+     option.
+
+     Command-line flags to sftp-server should be specified in the Subsystem
+     declaration.  See sshd_config(5) for more information.
+
+     Valid options are:
+
+     -d start_directory
+             specifies an alternate starting directory for users.  The
+             pathname may contain the following tokens that are expanded at
+             runtime: %% is replaced by a literal '%', %d is replaced by the
+             home directory of the user being authenticated, and %u is
+             replaced by the username of that user.  The default is to use the
+             user's home directory.  This option is useful in conjunction with
+             the sshd_config(5) ChrootDirectory option.
+
+     -e      Causes sftp-server to print logging information to stderr instead
+             of syslog for debugging.
+
+     -f log_facility
+             Specifies the facility code that is used when logging messages
+             from sftp-server.  The possible values are: DAEMON, USER, AUTH,
+             LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.
+             The default is AUTH.
+
+     -h      Displays sftp-server usage information.
+
+     -l log_level
+             Specifies which messages will be logged by sftp-server.  The
+             possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG,
+             DEBUG1, DEBUG2, and DEBUG3.  INFO and VERBOSE log transactions
+             that sftp-server performs on behalf of the client.  DEBUG and
+             DEBUG1 are equivalent.  DEBUG2 and DEBUG3 each specify higher
+             levels of debugging output.  The default is ERROR.
+
+     -P blacklisted_requests
+             Specify a comma-separated list of SFTP protocol requests that are
+             banned by the server.  sftp-server will reply to any blacklisted
+             request with a failure.  The -Q flag can be used to determine the
+             supported request types.  If both a blacklist and a whitelist are
+             specified, then the blacklist is applied before the whitelist.
+
+     -p whitelisted_requests
+             Specify a comma-separated list of SFTP protocol requests that are
+             permitted by the server.  All request types that are not on the
+             whitelist will be logged and replied to with a failure message.
+
+             Care must be taken when using this feature to ensure that
+             requests made implicitly by SFTP clients are permitted.
+
+     -Q protocol_feature
+             Query protocol features supported by sftp-server.  At present the
+             only feature that may be queried is M-bM-^@M-^\requestsM-bM-^@M-^], which may be used
+             for black or whitelisting (flags -P and -p respectively).
+
+     -R      Places this instance of sftp-server into a read-only mode.
+             Attempts to open files for writing, as well as other operations
+             that change the state of the filesystem, will be denied.
+
+     -u umask
+             Sets an explicit umask(2) to be applied to newly-created files
+             and directories, instead of the user's default mask.
+
+     On some systems, sftp-server must be able to access /dev/log for logging
+     to work, and use of sftp-server in a chroot configuration therefore
+     requires that syslogd(8) establish a logging socket inside the chroot
+     directory.

+SFTP(1)                     General Commands Manual                    SFTP(1)
+
+NAME
+     sftp M-bM-^@M-^S secure file transfer program
+
+SYNOPSIS
+     sftp [-46aCfpqrv] [-B buffer_size] [-b batchfile] [-c cipher]
+          [-D sftp_server_path] [-F ssh_config] [-i identity_file] [-l limit]
+          [-o ssh_option] [-P port] [-R num_requests] [-S program]
+          [-s subsystem | sftp_server] destination
+
+DESCRIPTION
+     sftp is a file transfer program, similar to ftp(1), which performs all
+     operations over an encrypted ssh(1) transport.  It may also use many
+     features of ssh, such as public key authentication and compression.
+
+     The destination may be specified either as [user@]host[:path] or as a URI
+     in the form sftp://[user@]host[:port][/path].
+
+     If the destination includes a path and it is not a directory, sftp will
+     retrieve files automatically if a non-interactive authentication method
+     is used; otherwise it will do so after successful interactive
+     authentication.
+
+     If no path is specified, or if the path is a directory, sftp will log in
+     to the specified host and enter interactive command mode, changing to the
+     remote directory if one was specified.  An optional trailing slash can be
+     used to force the path to be interpreted as a directory.
+
+     Since the destination formats use colon characters to delimit host names
+     from path names or port numbers, IPv6 addresses must be enclosed in
+     square brackets to avoid ambiguity.
+
+     The options are as follows:
+
+     -4      Forces sftp to use IPv4 addresses only.
+
+     -6      Forces sftp to use IPv6 addresses only.
+
+     -a      Attempt to continue interrupted transfers rather than overwriting
+             existing partial or complete copies of files.  If the partial
+             contents differ from those being transferred, then the resultant
+             file is likely to be corrupt.
+
+     -B buffer_size
+             Specify the size of the buffer that sftp uses when transferring
+             files.  Larger buffers require fewer round trips at the cost of
+             higher memory consumption.  The default is 32768 bytes.
+
+     -b batchfile
+             Batch mode reads a series of commands from an input batchfile
+             instead of stdin.  Since it lacks user interaction it should be
+             used in conjunction with non-interactive authentication to
+             obviate the need to enter a password at connection time (see
+             sshd(8) and ssh-keygen(1) for details).  A batchfile of M-bM-^@M-^X-M-bM-^@M-^Y may
+             be used to indicate standard input.  sftp will abort if any of
+             the following commands fail: get, put, reget, reput, rename, ln,
+             rm, mkdir, chdir, ls, lchdir, chmod, chown, chgrp, lpwd, df,
+             symlink, and lmkdir.  Termination on error can be suppressed on a
+             command by command basis by prefixing the command with a M-bM-^@M-^X-M-bM-^@M-^Y
+             character (for example, -rm /tmp/blah*).
+
+     -C      Enables compression (via ssh's -C flag).
+
+     -c cipher
+             Selects the cipher to use for encrypting the data transfers.
+             This option is directly passed to ssh(1).
+
+     -D sftp_server_path
+             Connect directly to a local sftp server (rather than via ssh(1)).
+             This option may be useful in debugging the client and server.
+
+     -F ssh_config
+             Specifies an alternative per-user configuration file for ssh(1).
+             This option is directly passed to ssh(1).
+
+     -f      Requests that files be flushed to disk immediately after
+             transfer.  When uploading files, this feature is only enabled if
+             the server implements the "fsync@openssh.com" extension.
+
+     -i identity_file
+             Selects the file from which the identity (private key) for public
+             key authentication is read.  This option is directly passed to
+             ssh(1).
+
+     -l limit
+             Limits the used bandwidth, specified in Kbit/s.
+
+     -o ssh_option
+             Can be used to pass options to ssh in the format used in
+             ssh_config(5).  This is useful for specifying options for which
+             there is no separate sftp command-line flag.  For example, to
+             specify an alternate port use: sftp -oPort=24.  For full details
+             of the options listed below, and their possible values, see
+             ssh_config(5).

+
+     -P port
+             Specifies the port to connect to on the remote host.
+
+     -p      Preserves modification times, access times, and modes from the
+             original files transferred.
+
+     -q      Quiet mode: disables the progress meter as well as warning and
+             diagnostic messages from ssh(1).
+
+     -R num_requests
+             Specify how many requests may be outstanding at any one time.
+             Increasing this may slightly improve file transfer speed but will
+             increase memory usage.  The default is 64 outstanding requests.
+
+     -r      Recursively copy entire directories when uploading and
+             downloading.  Note that sftp does not follow symbolic links
+             encountered in the tree traversal.
+
+     -S program
+             Name of the program to use for the encrypted connection.  The
+             program must understand ssh(1) options.
+
+     -s subsystem | sftp_server
+             Specifies the SSH2 subsystem or the path for an sftp server on
+             the remote host.  A path is useful when the remote sshd(8) does
+             not have an sftp subsystem configured.
+
+     -v      Raise logging level.  This option is also passed to ssh.
+
+INTERACTIVE COMMANDS
+     Once in interactive mode, sftp understands a set of commands similar to
+     those of ftp(1).  Commands are case insensitive.  Pathnames that contain
+     spaces must be enclosed in quotes.  Any special characters contained
+     within pathnames that are recognized by glob(3) must be escaped with
+     backslashes (M-bM-^@M-^X\M-bM-^@M-^Y).
+
+     bye     Quit sftp.
+
+     cd [path]
+             Change remote directory to path.  If path is not specified, then
+             change directory to the one the session started in.
+
+     chgrp grp path
+             Change group of file path to grp.  path may contain glob(7)
+             characters and may match multiple files.  grp must be a numeric
+             GID.
+
+     chmod mode path
+             Change permissions of file path to mode.  path may contain
+             glob(7) characters and may match multiple files.
+
+     chown own path
+             Change owner of file path to own.  path may contain glob(7)
+             characters and may match multiple files.  own must be a numeric
+             UID.
+
+     df [-hi] [path]
+             Display usage information for the filesystem holding the current
+             directory (or path if specified).  If the -h flag is specified,
+             the capacity information will be displayed using "human-readable"
+             suffixes.  The -i flag requests display of inode information in
+             addition to capacity information.  This command is only supported
+             on servers that implement the M-bM-^@M-^\statvfs@openssh.comM-bM-^@M-^] extension.
+
+     exit    Quit sftp.
+
+     get [-afPpr] remote-path [local-path]
+             Retrieve the remote-path and store it on the local machine.  If
+             the local path name is not specified, it is given the same name
+             it has on the remote machine.  remote-path may contain glob(7)
+             characters and may match multiple files.  If it does and
+             local-path is specified, then local-path must specify a
+             directory.
+
+             If the -a flag is specified, then attempt to resume partial
+             transfers of existing files.  Note that resumption assumes that
+             any partial copy of the local file matches the remote copy.  If
+             the remote file contents differ from the partial local copy then
+             the resultant file is likely to be corrupt.
+
+             If the -f flag is specified, then fsync(2) will be called after
+             the file transfer has completed to flush the file to disk.
+
+             If either the -P or -p flag is specified, then full file
+             permissions and access times are copied too.
+
+             If the -r flag is specified then directories will be copied
+             recursively.  Note that sftp does not follow symbolic links when
+             performing recursive transfers.
+
+     help    Display help text.
+
+     lcd [path]
+             Change local directory to path.  If path is not specified, then
+             change directory to the local user's home directory.
+
+     lls [ls-options [path]]
+             Display local directory listing of either path or current
+             directory if path is not specified.  ls-options may contain any
+             flags supported by the local system's ls(1) command.  path may
+             contain glob(7) characters and may match multiple files.
+
+     lmkdir path
+             Create local directory specified by path.
+
+     ln [-s] oldpath newpath
+             Create a link from oldpath to newpath.  If the -s flag is
+             specified the created link is a symbolic link, otherwise it is a
+             hard link.
+
+     lpwd    Print local working directory.
+
+     ls [-1afhlnrSt] [path]
+             Display a remote directory listing of either path or the current
+             directory if path is not specified.  path may contain glob(7)
+             characters and may match multiple files.
+
+             The following flags are recognized and alter the behaviour of ls
+             accordingly:
+
+             -1      Produce single columnar output.
+
+             -a      List files beginning with a dot (M-bM-^@M-^X.M-bM-^@M-^Y).
+
+             -f      Do not sort the listing.  The default sort order is
+                     lexicographical.
+
+             -h      When used with a long format option, use unit suffixes:
+                     Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte,
+                     and Exabyte in order to reduce the number of digits to
+                     four or fewer using powers of 2 for sizes (K=1024,
+                     M=1048576, etc.).
+
+             -l      Display additional details including permissions and
+                     ownership information.
+
+             -n      Produce a long listing with user and group information
+                     presented numerically.
+
+             -r      Reverse the sort order of the listing.
+
+             -S      Sort the listing by file size.
+
+             -t      Sort the listing by last modification time.
+
+     lumask umask
+             Set local umask to umask.
+
+     mkdir path
+             Create remote directory specified by path.
+
+     progress
+             Toggle display of progress meter.
+
+     put [-afPpr] local-path [remote-path]
+             Upload local-path and store it on the remote machine.  If the
+             remote path name is not specified, it is given the same name it
+             has on the local machine.  local-path may contain glob(7)
+             characters and may match multiple files.  If it does and
+             remote-path is specified, then remote-path must specify a
+             directory.
+
+             If the -a flag is specified, then attempt to resume partial
+             transfers of existing files.  Note that resumption assumes that
+             any partial copy of the remote file matches the local copy.  If
+             the local file contents differ from the remote local copy then
+             the resultant file is likely to be corrupt.
+
+             If the -f flag is specified, then a request will be sent to the
+             server to call fsync(2) after the file has been transferred.
+             Note that this is only supported by servers that implement the
+             "fsync@openssh.com" extension.
+
+             If either the -P or -p flag is specified, then full file
+             permissions and access times are copied too.
+
+             If the -r flag is specified then directories will be copied
+             recursively.  Note that sftp does not follow symbolic links when

+
+NAME
+     ssh-add M-bM-^@M-^S adds private key identities to the authentication agent
+
+SYNOPSIS
+     ssh-add [-cDdkLlqXx] [-E fingerprint_hash] [-t life] [file ...]
+     ssh-add -s pkcs11
+     ssh-add -e pkcs11
+
+DESCRIPTION
+     ssh-add adds private key identities to the authentication agent,
+     ssh-agent(1).  When run without arguments, it adds the files
+     ~/.ssh/id_rsa, ~/.ssh/id_dsa, ~/.ssh/id_ecdsa, and ~/.ssh/id_ed25519.
+     After loading a private key, ssh-add will try to load corresponding
+     certificate information from the filename obtained by appending -cert.pub
+     to the name of the private key file.  Alternative file names can be given
+     on the command line.
+
+     If any file requires a passphrase, ssh-add asks for the passphrase from
+     the user.  The passphrase is read from the user's tty.  ssh-add retries
+     the last passphrase if multiple identity files are given.
+
+     The authentication agent must be running and the SSH_AUTH_SOCK
+     environment variable must contain the name of its socket for ssh-add to
+     work.
+
+     The options are as follows:
+
+     -c      Indicates that added identities should be subject to confirmation
+             before being used for authentication.  Confirmation is performed
+             by ssh-askpass(1).  Successful confirmation is signaled by a zero
+             exit status from ssh-askpass(1), rather than text entered into
+             the requester.
+
+     -D      Deletes all identities from the agent.
+
+     -d      Instead of adding identities, removes identities from the agent.
+             If ssh-add has been run without arguments, the keys for the
+             default identities and their corresponding certificates will be
+             removed.  Otherwise, the argument list will be interpreted as a
+             list of paths to public key files to specify keys and
+             certificates to be removed from the agent.  If no public key is
+             found at a given path, ssh-add will append .pub and retry.
+
+     -E fingerprint_hash
+             Specifies the hash algorithm used when displaying key
+             fingerprints.  Valid options are: M-bM-^@M-^\md5M-bM-^@M-^] and M-bM-^@M-^\sha256M-bM-^@M-^].  The
+             default is M-bM-^@M-^\sha256M-bM-^@M-^].
+
+     -e pkcs11
+             Remove keys provided by the PKCS#11 shared library pkcs11.
+
+     -k      When loading keys into or deleting keys from the agent, process
+             plain private keys only and skip certificates.
+
+     -L      Lists public key parameters of all identities currently
+             represented by the agent.
+
+     -l      Lists fingerprints of all identities currently represented by the
+             agent.
+
+     -q      Be quiet after a successful operation.
+
+     -s pkcs11
+             Add keys provided by the PKCS#11 shared library pkcs11.
+
+     -t life
+             Set a maximum lifetime when adding identities to an agent.  The
+             lifetime may be specified in seconds or in a time format
+             specified in sshd_config(5).
+
+     -X      Unlock the agent.
+
+     -x      Lock the agent with a password.
+
+ENVIRONMENT
+     DISPLAY and SSH_ASKPASS
+             If ssh-add needs a passphrase, it will read the passphrase from
+             the current terminal if it was run from a terminal.  If ssh-add
+             does not have a terminal associated with it but DISPLAY and
+             SSH_ASKPASS are set, it will execute the program specified by
+             SSH_ASKPASS (by default M-bM-^@M-^\ssh-askpassM-bM-^@M-^]) and open an X11 window to
+             read the passphrase.  This is particularly useful when calling
+             ssh-add from a .xsession or related script.  (Note that on some
+             machines it may be necessary to redirect the input from /dev/null
+             to make this work.)
+
+     SSH_AUTH_SOCK
+             Identifies the path of a UNIX-domain socket used to communicate
+             with the agent.

+SSH-AGENT(1)                General Commands Manual               SSH-AGENT(1)
+
+NAME
+     ssh-agent M-bM-^@M-^S authentication agent
+
+SYNOPSIS
+     ssh-agent [-c | -s] [-Dd] [-a bind_address] [-E fingerprint_hash]
+               [-P pkcs11_whitelist] [-t life] [command [arg ...]]
+     ssh-agent [-c | -s] -k
+
+DESCRIPTION
+     ssh-agent is a program to hold private keys used for public key
+     authentication (RSA, DSA, ECDSA, Ed25519).  ssh-agent is usually started
+     in the beginning of an X-session or a login session, and all other
+     windows or programs are started as clients to the ssh-agent program.
+     Through use of environment variables the agent can be located and
+     automatically used for authentication when logging in to other machines
+     using ssh(1).
+
+     The agent initially does not have any private keys.  Keys are added using
+     ssh(1) (see AddKeysToAgent in ssh_config(5) for details) or ssh-add(1).
+     Multiple identities may be stored in ssh-agent concurrently and ssh(1)
+     will automatically use them if present.  ssh-add(1) is also used to
+     remove keys from ssh-agent and to query the keys that are held in one.
+
+     The options are as follows:
+
+     -a bind_address
+             Bind the agent to the UNIX-domain socket bind_address.  The
+             default is $TMPDIR/ssh-XXXXXXXXXX/agent.<ppid>.
+
+     -c      Generate C-shell commands on stdout.  This is the default if
+             SHELL looks like it's a csh style of shell.
+
+     -D      Foreground mode.  When this option is specified ssh-agent will
+             not fork.
+
+     -d      Debug mode.  When this option is specified ssh-agent will not
+             fork and will write debug information to standard error.
+
+     -E fingerprint_hash
+             Specifies the hash algorithm used when displaying key
+             fingerprints.  Valid options are: M-bM-^@M-^\md5M-bM-^@M-^] and M-bM-^@M-^\sha256M-bM-^@M-^].  The
+             default is M-bM-^@M-^\sha256M-bM-^@M-^].
+
+     -k      Kill the current agent (given by the SSH_AGENT_PID environment
+             variable).
+
+     -P pkcs11_whitelist
+             Specify a pattern-list of acceptable paths for PKCS#11 shared
+             libraries that may be added using the -s option to ssh-add(1).
+             The default is to allow loading PKCS#11 libraries from
+             M-bM-^@M-^\/usr/lib/*,/usr/local/lib/*M-bM-^@M-^].  PKCS#11 libraries that do not
+             match the whitelist will be refused.  See PATTERNS in
+             ssh_config(5) for a description of pattern-list syntax.
+
+     -s      Generate Bourne shell commands on stdout.  This is the default if
+             SHELL does not look like it's a csh style of shell.
+
+     -t life
+             Set a default value for the maximum lifetime of identities added
+             to the agent.  The lifetime may be specified in seconds or in a
+             time format specified in sshd_config(5).  A lifetime specified
+             for an identity with ssh-add(1) overrides this value.  Without
+             this option the default maximum lifetime is forever.
+
+     If a command line is given, this is executed as a subprocess of the
+     agent.  When the command dies, so does the agent.
+
+     The idea is that the agent is run in the user's local PC, laptop, or
+     terminal.  Authentication data need not be stored on any other machine,
+     and authentication passphrases never go over the network.  However, the
+     connection to the agent is forwarded over SSH remote logins, and the user
+     can thus use the privileges given by the identities anywhere in the
+     network in a secure way.
+
+     There are two main ways to get an agent set up: The first is that the
+     agent starts a new subcommand into which some environment variables are
+     exported, eg ssh-agent xterm &.  The second is that the agent prints the
+     needed shell commands (either sh(1) or csh(1) syntax can be generated)
+     which can be evaluated in the calling shell, eg eval `ssh-agent -s` for
+     Bourne-type shells such as sh(1) or ksh(1) and eval `ssh-agent -c` for
+     csh(1) and derivatives.
+
+     Later ssh(1) looks at these variables and uses them to establish a
+     connection to the agent.
+
+     The agent will never send a private key over its request channel.
+     Instead, operations that require a private key will be performed by the
+     agent, and the result will be returned to the requester.  This way,
+     private keys are not exposed to clients using the agent.
+
+     A UNIX-domain socket is created and the name of this socket is stored in
+     the SSH_AUTH_SOCK environment variable.  The socket is made accessible
+     only to the current user.  This method is easily abused by root or
+     another instance of the same user.
+
+     The SSH_AGENT_PID environment variable holds the agent's process ID.
+
+     The agent exits automatically when the command given on the command line
+     terminates.
+
+FILES
+     $TMPDIR/ssh-XXXXXXXXXX/agent.<ppid>
+             UNIX-domain sockets used to contain the connection to the
+             authentication agent.  These sockets should only be readable by
+             the owner.  The sockets should get automatically removed when the
+             agent exits.

+DESCRIPTION
+     ssh-keygen generates, manages and converts authentication keys for
+     ssh(1).  ssh-keygen can create keys for use by SSH protocol version 2.
+
+     The type of key to be generated is specified with the -t option.  If
+     invoked without any arguments, ssh-keygen will generate an RSA key.
+
+     ssh-keygen is also used to generate groups for use in Diffie-Hellman
+     group exchange (DH-GEX).  See the MODULI GENERATION section for details.
+
+     Finally, ssh-keygen can be used to generate and update Key Revocation
+     Lists, and to test whether given keys have been revoked by one.  See the
+     KEY REVOCATION LISTS section for details.
+
+     Normally each user wishing to use SSH with public key authentication runs
+     this once to create the authentication key in ~/.ssh/id_dsa,
+     ~/.ssh/id_ecdsa, ~/.ssh/id_ed25519 or ~/.ssh/id_rsa.  Additionally, the
+     system administrator may use this to generate host keys, as seen in
+     /etc/rc.
+
+     Normally this program generates the key and asks for a file in which to
+     store the private key.  The public key is stored in a file with the same
+     name but M-bM-^@M-^\.pubM-bM-^@M-^] appended.  The program also asks for a passphrase.  The
+     passphrase may be empty to indicate no passphrase (host keys must have an
+     empty passphrase), or it may be a string of arbitrary length.  A
+     passphrase is similar to a password, except it can be a phrase with a
+     series of words, punctuation, numbers, whitespace, or any string of
+     characters you want.  Good passphrases are 10-30 characters long, are not
+     simple sentences or otherwise easily guessable (English prose has only
+     1-2 bits of entropy per character, and provides very bad passphrases),
+     and contain a mix of upper and lowercase letters, numbers, and non-
+     alphanumeric characters.  The passphrase can be changed later by using
+     the -p option.
+
+     There is no way to recover a lost passphrase.  If the passphrase is lost
+     or forgotten, a new key must be generated and the corresponding public
+     key copied to other machines.
+
+     For keys stored in the newer OpenSSH format, there is also a comment
+     field in the key file that is only for convenience to the user to help
+     identify the key.  The comment can tell what the key is for, or whatever
+     is useful.  The comment is initialized to M-bM-^@M-^\user@hostM-bM-^@M-^] when the key is
+     created, but can be changed using the -c option.
+
+     After a key is generated, instructions below detail where the keys should
+     be placed to be activated.
+
+     The options are as follows:
+
+     -A      For each of the key types (rsa, dsa, ecdsa and ed25519) for which
+             host keys do not exist, generate the host keys with the default
+             key file path, an empty passphrase, default bits for the key
+             type, and default comment.  If -f has also been specified, its
+             argument is used as a prefix to the default path for the
+             resulting host key files.  This is used by /etc/rc to generate
+             new host keys.
+
+     -a rounds
+             When saving a private key this option specifies the number of KDF
+             (key derivation function) rounds used.  Higher numbers result in
+             slower passphrase verification and increased resistance to brute-
+             force password cracking (should the keys be stolen).
+
+             When screening DH-GEX candidates (using the -T command).  This
+             option specifies the number of primality tests to perform.
+
+     -B      Show the bubblebabble digest of specified private or public key
+             file.
+
+     -b bits
+             Specifies the number of bits in the key to create.  For RSA keys,
+             the minimum size is 1024 bits and the default is 2048 bits.
+             Generally, 2048 bits is considered sufficient.  DSA keys must be
+             exactly 1024 bits as specified by FIPS 186-2.  For ECDSA keys,
+             the -b flag determines the key length by selecting from one of
+             three elliptic curve sizes: 256, 384 or 521 bits.  Attempting to
+             use bit lengths other than these three values for ECDSA keys will
+             fail.  Ed25519 keys have a fixed length and the -b flag will be
+             ignored.
+
+     -C comment
+             Provides a new comment.
+
+     -c      Requests changing the comment in the private and public key
+             files.  The program will prompt for the file containing the
+             private keys, for the passphrase if the key has one, and for the
+             new comment.
+
+     -D pkcs11
+             Download the RSA public keys provided by the PKCS#11 shared
+             library pkcs11.  When used in combination with -s, this option
+             indicates that a CA key resides in a PKCS#11 token (see the
+             CERTIFICATES section for details).
+
+     -E fingerprint_hash
+             Specifies the hash algorithm used when displaying key
+             fingerprints.  Valid options are: M-bM-^@M-^\md5M-bM-^@M-^] and M-bM-^@M-^\sha256M-bM-^@M-^].  The
+             default is M-bM-^@M-^\sha256M-bM-^@M-^].
+
+     -e      This option will read a private or public OpenSSH key file and
+             print to stdout the key in one of the formats specified by the -m
+             option.  The default export format is M-bM-^@M-^\RFC4716M-bM-^@M-^].  This option
+             allows exporting OpenSSH keys for use by other programs,
+             including several commercial SSH implementations.
+
+     -F hostname
+             Search for the specified hostname in a known_hosts file, listing
+             any occurrences found.  This option is useful to find hashed host
+             names or addresses and may also be used in conjunction with the
+             -H option to print found keys in a hashed format.
+
+     -f filename
+             Specifies the filename of the key file.
+
+     -G output_file
+             Generate candidate primes for DH-GEX.  These primes must be
+             screened for safety (using the -T option) before use.
+
+     -g      Use generic DNS format when printing fingerprint resource records
+             using the -r command.
+
+     -H      Hash a known_hosts file.  This replaces all hostnames and
+             addresses with hashed representations within the specified file;
+             the original content is moved to a file with a .old suffix.
+             These hashes may be used normally by ssh and sshd, but they do
+             not reveal identifying information should the file's contents be
+             disclosed.  This option will not modify existing hashed hostnames
+             and is therefore safe to use on files that mix hashed and non-
+             hashed names.
+
+     -h      When signing a key, create a host certificate instead of a user
+             certificate.  Please see the CERTIFICATES section for details.
+
+     -I certificate_identity
+             Specify the key identity when signing a public key.  Please see
+             the CERTIFICATES section for details.
+
+     -i      This option will read an unencrypted private (or public) key file
+             in the format specified by the -m option and print an OpenSSH
+             compatible private (or public) key to stdout.  This option allows
+             importing keys from other software, including several commercial
+             SSH implementations.  The default import format is M-bM-^@M-^\RFC4716M-bM-^@M-^].
+
+     -J num_lines
+             Exit after screening the specified number of lines while
+             performing DH candidate screening using the -T option.
+
+     -j start_line
+             Start screening at the specified line number while performing DH
+             candidate screening using the -T option.
+
+     -K checkpt
+             Write the last line processed to the file checkpt while
+             performing DH candidate screening using the -T option.  This will
+             be used to skip lines in the input file that have already been
+             processed if the job is restarted.
+
+     -k      Generate a KRL file.  In this mode, ssh-keygen will generate a
+             KRL file at the location specified via the -f flag that revokes
+             every key or certificate presented on the command line.
+             Keys/certificates to be revoked may be specified by public key
+             file or using the format described in the KEY REVOCATION LISTS
+             section.
+
+     -L      Prints the contents of one or more certificates.
+
+     -l      Show fingerprint of specified public key file.  For RSA and DSA
+             keys ssh-keygen tries to find the matching public key file and
+             prints its fingerprint.  If combined with -v, a visual ASCII art
+             representation of the key is supplied with the fingerprint.
+
+     -M memory
+             Specify the amount of memory to use (in megabytes) when
+             generating candidate moduli for DH-GEX.
+
+     -m key_format
+             Specify a key format for the -i (import) or -e (export)
+             conversion options.  The supported key formats are: M-bM-^@M-^\RFC4716M-bM-^@M-^]
+             (RFC 4716/SSH2 public or private key), M-bM-^@M-^\PKCS8M-bM-^@M-^] (PEM PKCS8 public
+             key) or M-bM-^@M-^\PEMM-bM-^@M-^] (PEM public key).  The default conversion format is
+             M-bM-^@M-^\RFC4716M-bM-^@M-^].  Setting a format of M-bM-^@M-^\PEMM-bM-^@M-^] when generating or updating
+             a supported private key type will cause the key to be stored in
+             the legacy PEM private key format.
+
+     -N new_passphrase
+             Provides the new passphrase.
+
+     -n principals
+             Specify one or more principals (user or host names) to be
+             included in a certificate when signing a key.  Multiple
+             principals may be specified, separated by commas.  Please see the
+             CERTIFICATES section for details.
+
+     -O option
+             Specify a certificate option when signing a key.  This option may
+             be specified multiple times.  See also the CERTIFICATES section
+             for further details.
+
+             At present, no standard options are valid for host keys.  The
+             options that are valid for user certificates are:
+
+             clear   Clear all enabled permissions.  This is useful for
+                     clearing the default set of permissions so permissions
+                     may be added individually.
+
+             critical:name[=contents]
+             extension:name[=contents]
+                     Includes an arbitrary certificate critical option or
+                     extension.  The specified name should include a domain
+                     suffix, e.g. M-bM-^@M-^\name@example.comM-bM-^@M-^].  If contents is
+                     specified then it is included as the contents of the
+                     extension/option encoded as a string, otherwise the
+                     extension/option is created with no contents (usually
+                     indicating a flag).  Extensions may be ignored by a
+                     client or server that does not recognise them, whereas
+                     unknown critical options will cause the certificate to be
+                     refused.
+
+             force-command=command
+                     Forces the execution of command instead of any shell or
+                     command specified by the user when the certificate is
+                     used for authentication.
+
+             no-agent-forwarding
+                     Disable ssh-agent(1) forwarding (permitted by default).
+
+             no-port-forwarding
+                     Disable port forwarding (permitted by default).
+
+             no-pty  Disable PTY allocation (permitted by default).
+
+             no-user-rc
+                     Disable execution of ~/.ssh/rc by sshd(8) (permitted by
+                     default).
+
+             no-x11-forwarding
+                     Disable X11 forwarding (permitted by default).
+
+             permit-agent-forwarding
+                     Allows ssh-agent(1) forwarding.
+
+             permit-port-forwarding
+                     Allows port forwarding.
+
+             permit-pty
+                     Allows PTY allocation.
+
+             permit-user-rc
+                     Allows execution of ~/.ssh/rc by sshd(8).
+
+             permit-X11-forwarding
+                     Allows X11 forwarding.
+
+             source-address=address_list
+                     Restrict the source addresses from which the certificate
+                     is considered valid.  The address_list is a comma-
+                     separated list of one or more address/netmask pairs in
+                     CIDR format.
+
+     -P passphrase
+             Provides the (old) passphrase.
+
+     -p      Requests changing the passphrase of a private key file instead of
+             creating a new private key.  The program will prompt for the file
+             containing the private key, for the old passphrase, and twice for
+             the new passphrase.
+
+     -Q      Test whether keys have been revoked in a KRL.
+
+     -q      Silence ssh-keygen.
+
+     -R hostname
+             Removes all keys belonging to hostname from a known_hosts file.
+             This option is useful to delete hashed hosts (see the -H option
+             above).
+
+     -r hostname
+             Print the SSHFP fingerprint resource record named hostname for
+             the specified public key file.
+
+     -S start
+             Specify start point (in hex) when generating candidate moduli for
+             DH-GEX.
+
+     -s ca_key
+             Certify (sign) a public key using the specified CA key.  Please
+             see the CERTIFICATES section for details.
+
+             When generating a KRL, -s specifies a path to a CA public key
+             file used to revoke certificates directly by key ID or serial
+             number.  See the KEY REVOCATION LISTS section for details.
+
+     -T output_file
+             Test DH group exchange candidate primes (generated using the -G
+             option) for safety.
+
+     -t dsa | ecdsa | ed25519 | rsa
+             Specifies the type of key to create.  The possible values are
+             M-bM-^@M-^\dsaM-bM-^@M-^], M-bM-^@M-^\ecdsaM-bM-^@M-^], M-bM-^@M-^\ed25519M-bM-^@M-^], or M-bM-^@M-^\rsaM-bM-^@M-^].
+
+     -U      When used in combination with -s, this option indicates that a CA
+             key resides in a ssh-agent(1).  See the CERTIFICATES section for
+             more information.
+
+     -u      Update a KRL.  When specified with -k, keys listed via the
+             command line are added to the existing KRL rather than a new KRL
+             being created.
+
+     -V validity_interval
+             Specify a validity interval when signing a certificate.  A
+             validity interval may consist of a single time, indicating that
+             the certificate is valid beginning now and expiring at that time,
+             or may consist of two times separated by a colon to indicate an
+             explicit time interval.
+
+             The start time may be specified as the string M-bM-^@M-^\alwaysM-bM-^@M-^] to
+             indicate the certificate has no specified start time, a date in
+             YYYYMMDD format, a time in YYYYMMDDHHMM[SS] format, a relative
+             time (to the current time) consisting of a minus sign followed by
+             an interval in the format described in the TIME FORMATS section
+             of sshd_config(5).
+
+             The end time may be specified as a YYYYMMDD date, a
+             YYYYMMDDHHMM[SS] time, a relative time starting with a plus
+             character or the string M-bM-^@M-^\foreverM-bM-^@M-^] to indicate that the
+             certificate has no expirty date.
+
+             For example: M-bM-^@M-^\+52w1dM-bM-^@M-^] (valid from now to 52 weeks and one day
+             from now), M-bM-^@M-^\-4w:+4wM-bM-^@M-^] (valid from four weeks ago to four weeks
+             from now), M-bM-^@M-^\20100101123000:20110101123000M-bM-^@M-^] (valid from 12:30 PM,
+             January 1st, 2010 to 12:30 PM, January 1st, 2011), M-bM-^@M-^\-1d:20110101M-bM-^@M-^]
+             (valid from yesterday to midnight, January 1st, 2011).
+             M-bM-^@M-^\-1m:foreverM-bM-^@M-^] (valid from one minute ago and never expiring).
+
+     -v      Verbose mode.  Causes ssh-keygen to print debugging messages
+             about its progress.  This is helpful for debugging moduli
+             generation.  Multiple -v options increase the verbosity.  The
+             maximum is 3.
+
+     -W generator
+             Specify desired generator when testing candidate moduli for DH-
+             GEX.
+
+     -y      This option will read a private OpenSSH format file and print an
+             OpenSSH public key to stdout.
+
+     -z serial_number
+             Specifies a serial number to be embedded in the certificate to
+             distinguish this certificate from others from the same CA.  The
+             default serial number is zero.
+
+             When generating a KRL, the -z flag is used to specify a KRL
+             version number.
+
+MODULI GENERATION
+     ssh-keygen may be used to generate groups for the Diffie-Hellman Group
+     Exchange (DH-GEX) protocol.  Generating these groups is a two-step
+     process: first, candidate primes are generated using a fast, but memory
+     intensive process.  These candidate primes are then tested for
+     suitability (a CPU-intensive process).
+
+     Generation of primes is performed using the -G option.  The desired
+     length of the primes may be specified by the -b option.  For example:
+
+           # ssh-keygen -G moduli-2048.candidates -b 2048
+
+     By default, the search for primes begins at a random point in the desired
+     length range.  This may be overridden using the -S option, which
+     specifies a different start point (in hex).
+
+     Once a set of candidates have been generated, they must be screened for
+     suitability.  This may be performed using the -T option.  In this mode
+     ssh-keygen will read candidates from standard input (or a file specified
+     using the -f option).  For example:
+
+           # ssh-keygen -T moduli-2048 -f moduli-2048.candidates
+
+     By default, each candidate will be subjected to 100 primality tests.
+     This may be overridden using the -a option.  The DH generator value will
+     be chosen automatically for the prime under consideration.  If a specific
+     generator is desired, it may be requested using the -W option.  Valid
+     generator values are 2, 3, and 5.
+
+     Screened DH groups may be installed in /etc/moduli.  It is important that
+     this file contains moduli of a range of bit lengths and that both ends of
+     a connection share common moduli.
+
+CERTIFICATES
+     ssh-keygen supports signing of keys to produce certificates that may be
+     used for user or host authentication.  Certificates consist of a public
+     key, some identity information, zero or more principal (user or host)
+     names and a set of options that are signed by a Certification Authority
+     (CA) key.  Clients or servers may then trust only the CA key and verify
+     its signature on a certificate rather than trusting many user/host keys.
+     Note that OpenSSH certificates are a different, and much simpler, format
+     to the X.509 certificates used in ssl(8).
+
+     ssh-keygen supports two types of certificates: user and host.  User
+     certificates authenticate users to servers, whereas host certificates
+     authenticate server hosts to users.  To generate a user certificate:
+
+           $ ssh-keygen -s /path/to/ca_key -I key_id /path/to/user_key.pub
+
+     The resultant certificate will be placed in /path/to/user_key-cert.pub.
+     A host certificate requires the -h option:
+
+           $ ssh-keygen -s /path/to/ca_key -I key_id -h /path/to/host_key.pub
+
+     The host certificate will be output to /path/to/host_key-cert.pub.
+
+     It is possible to sign using a CA key stored in a PKCS#11 token by
+     providing the token library using -D and identifying the CA key by
+     providing its public half as an argument to -s:
+
+           $ ssh-keygen -s ca_key.pub -D libpkcs11.so -I key_id user_key.pub
+
+     Similarly, it is possible for the CA key to be hosted in a ssh-agent(1).
+     This is indicated by the -U flag and, again, the CA key must be
+     identified by its public half.
+
+           $ ssh-keygen -Us ca_key.pub -I key_id user_key.pub
+
+     In all cases, key_id is a "key identifier" that is logged by the server
+     when the certificate is used for authentication.
+
+     Certificates may be limited to be valid for a set of principal
+     (user/host) names.  By default, generated certificates are valid for all
+     users or hosts.  To generate a certificate for a specified set of
+     principals:
+
+           $ ssh-keygen -s ca_key -I key_id -n user1,user2 user_key.pub
+           $ ssh-keygen -s ca_key -I key_id -h -n host.domain host_key.pub
+
+     Additional limitations on the validity and use of user certificates may
+     be specified through certificate options.  A certificate option may
+     disable features of the SSH session, may be valid only when presented
+     from particular source addresses or may force the use of a specific
+     command.  For a list of valid certificate options, see the documentation
+     for the -O option above.
+
+     Finally, certificates may be defined with a validity lifetime.  The -V
+     option allows specification of certificate start and end times.  A
+     certificate that is presented at a time outside this range will not be
+     considered valid.  By default, certificates are valid from UNIX Epoch to
+     the distant future.
+
+     For certificates to be used for user or host authentication, the CA
+     public key must be trusted by sshd(8) or ssh(1).  Please refer to those
+     manual pages for details.
+
+KEY REVOCATION LISTS
+     ssh-keygen is able to manage OpenSSH format Key Revocation Lists (KRLs).
+     These binary files specify keys or certificates to be revoked using a
+     compact format, taking as little as one bit per certificate if they are
+     being revoked by serial number.
+
+     KRLs may be generated using the -k flag.  This option reads one or more
+     files from the command line and generates a new KRL.  The files may
+     either contain a KRL specification (see below) or public keys, listed one
+     per line.  Plain public keys are revoked by listing their hash or
+     contents in the KRL and certificates revoked by serial number or key ID
+     (if the serial is zero or not available).
+
+     Revoking keys using a KRL specification offers explicit control over the
+     types of record used to revoke keys and may be used to directly revoke
+     certificates by serial number or key ID without having the complete
+     original certificate on hand.  A KRL specification consists of lines
+     containing one of the following directives followed by a colon and some
+     directive-specific information.
+
+     serial: serial_number[-serial_number]
+             Revokes a certificate with the specified serial number.  Serial
+             numbers are 64-bit values, not including zero and may be
+             expressed in decimal, hex or octal.  If two serial numbers are
+             specified separated by a hyphen, then the range of serial numbers
+             including and between each is revoked.  The CA key must have been
+             specified on the ssh-keygen command line using the -s option.
+
+     id: key_id
+             Revokes a certificate with the specified key ID string.  The CA
+             key must have been specified on the ssh-keygen command line using
+             the -s option.
+
+     key: public_key
+             Revokes the specified key.  If a certificate is listed, then it
+             is revoked as a plain public key.
+
+     sha1: public_key
+             Revokes the specified key by including its SHA1 hash in the KRL.
+
+     sha256: public_key
+             Revokes the specified key by including its SHA256 hash in the
+             KRL.  KRLs that revoke keys by SHA256 hash are not supported by
+             OpenSSH versions prior to 7.9.
+
+     hash: fingerprint
+             Revokes a key using a fingerprint hash, as obtained from a
+             sshd(8) authentication log message or the ssh-keygen -l flag.
+             Only SHA256 fingerprints are supported here and resultant KRLs
+             are not supported by OpenSSH versions prior to 7.9.
+
+     KRLs may be updated using the -u flag in addition to -k.  When this
+     option is specified, keys listed via the command line are merged into the
+     KRL, adding to those already there.
+
+     It is also possible, given a KRL, to test whether it revokes a particular
+     key (or keys).  The -Q flag will query an existing KRL, testing each key
+     specified on the command line.  If any key listed on the command line has
+     been revoked (or an error encountered) then ssh-keygen will exit with a
+     non-zero exit status.  A zero exit status will only be returned if no key
+     was revoked.

+
+NAME
+     ssh-keyscan M-bM-^@M-^S gather SSH public keys
+
+SYNOPSIS
+     ssh-keyscan [-46cDHv] [-f file] [-p port] [-T timeout] [-t type]
+                 [host | addrlist namelist]
+
+DESCRIPTION
+     ssh-keyscan is a utility for gathering the public SSH host keys of a
+     number of hosts.  It was designed to aid in building and verifying
+     ssh_known_hosts files, the format of which is documented in sshd(8).
+     ssh-keyscan provides a minimal interface suitable for use by shell and
+     perl scripts.
+
+     ssh-keyscan uses non-blocking socket I/O to contact as many hosts as
+     possible in parallel, so it is very efficient.  The keys from a domain of
+     1,000 hosts can be collected in tens of seconds, even when some of those
+     hosts are down or do not run sshd(8).  For scanning, one does not need
+     login access to the machines that are being scanned, nor does the
+     scanning process involve any encryption.
+
+     The options are as follows:
+
+     -4      Force ssh-keyscan to use IPv4 addresses only.
+
+     -6      Force ssh-keyscan to use IPv6 addresses only.
+
+     -c      Request certificates from target hosts instead of plain keys.
+
+     -D      Print keys found as SSHFP DNS records.  The default is to print
+             keys in a format usable as a ssh(1) known_hosts file.
+
+     -f file
+             Read hosts or M-bM-^@M-^\addrlist namelistM-bM-^@M-^] pairs from file, one per line.
+             If M-bM-^@M-^X-M-bM-^@M-^Y is supplied instead of a filename, ssh-keyscan will read
+             from the standard input.  Input is expected in the format:
+
+             1.2.3.4,1.2.4.4 name.my.domain,name,n.my.domain,n,1.2.3.4,1.2.4.4
+
+     -H      Hash all hostnames and addresses in the output.  Hashed names may
+             be used normally by ssh(1) and sshd(8), but they do not reveal
+             identifying information should the file's contents be disclosed.
+
+     -p port
+             Connect to port on the remote host.
+
+     -T timeout
+             Set the timeout for connection attempts.  If timeout seconds have
+             elapsed since a connection was initiated to a host or since the
+             last time anything was read from that host, the connection is
+             closed and the host in question considered unavailable.  The
+             default is 5 seconds.
+
+     -t type
+             Specify the type of the key to fetch from the scanned hosts.  The

+
+NAME
+     ssh-keysign M-bM-^@M-^S ssh helper program for host-based authentication
+
+SYNOPSIS
+     ssh-keysign
+
+DESCRIPTION
+     ssh-keysign is used by ssh(1) to access the local host keys and generate
+     the digital signature required during host-based authentication.
+
+     ssh-keysign is disabled by default and can only be enabled in the global
+     client configuration file /etc/ssh/ssh_config by setting EnableSSHKeysign
+     to M-bM-^@M-^\yesM-bM-^@M-^].
+
+     ssh-keysign is not intended to be invoked by the user, but from ssh(1).
+     See ssh(1) and sshd(8) for more information about host-based
+     authentication.
+

+             These files contain the private parts of the host keys used to
+             generate the digital signature.  They should be owned by root,
+             readable only by root, and not accessible to others.  Since they
+             are readable only by root, ssh-keysign must be set-uid root if
+             host-based authentication is used.

+
+DESCRIPTION
+     ssh (SSH client) is a program for logging into a remote machine and for
+     executing commands on a remote machine.  It is intended to provide secure
+     encrypted communications between two untrusted hosts over an insecure
+     network.  X11 connections, arbitrary TCP ports and UNIX-domain sockets
+     can also be forwarded over the secure channel.
+
+     ssh connects and logs into the specified destination, which may be
+     specified as either [user@]hostname or a URI of the form
+     ssh://[user@]hostname[:port].  The user must prove his/her identity to
+     the remote machine using one of several methods (see below).
+
+     If a command is specified, it is executed on the remote host instead of a
+     login shell.
+
+     The options are as follows:
+
+     -4      Forces ssh to use IPv4 addresses only.
+
+     -6      Forces ssh to use IPv6 addresses only.
+
+     -A      Enables forwarding of the authentication agent connection.  This
+             can also be specified on a per-host basis in a configuration
+             file.
+
+             Agent forwarding should be enabled with caution.  Users with the
+             ability to bypass file permissions on the remote host (for the
+             agent's UNIX-domain socket) can access the local agent through
+             the forwarded connection.  An attacker cannot obtain key material
+             from the agent, however they can perform operations on the keys
+             that enable them to authenticate using the identities loaded into
+             the agent.
+
+     -a      Disables forwarding of the authentication agent connection.
+
+     -B bind_interface
+             Bind to the address of bind_interface before attempting to
+             connect to the destination host.  This is only useful on systems
+             with more than one address.
+
+     -b bind_address
+             Use bind_address on the local machine as the source address of
+             the connection.  Only useful on systems with more than one
+             address.
+
+     -C      Requests compression of all data (including stdin, stdout,
+             stderr, and data for forwarded X11, TCP and UNIX-domain
+             connections).  The compression algorithm is the same used by
+             gzip(1).  Compression is desirable on modem lines and other slow
+             connections, but will only slow down things on fast networks.
+             The default value can be set on a host-by-host basis in the
+             configuration files; see the Compression option.
+
+     -c cipher_spec
+             Selects the cipher specification for encrypting the session.
+             cipher_spec is a comma-separated list of ciphers listed in order
+             of preference.  See the Ciphers keyword in ssh_config(5) for more
+             information.
+
+     -D [bind_address:]port
+             Specifies a local M-bM-^@M-^\dynamicM-bM-^@M-^] application-level port forwarding.
+             This works by allocating a socket to listen to port on the local
+             side, optionally bound to the specified bind_address.  Whenever a
+             connection is made to this port, the connection is forwarded over
+             the secure channel, and the application protocol is then used to
+             determine where to connect to from the remote machine.  Currently
+             the SOCKS4 and SOCKS5 protocols are supported, and ssh will act
+             as a SOCKS server.  Only root can forward privileged ports.
+             Dynamic port forwardings can also be specified in the
+             configuration file.
+
+             IPv6 addresses can be specified by enclosing the address in
+             square brackets.  Only the superuser can forward privileged
+             ports.  By default, the local port is bound in accordance with
+             the GatewayPorts setting.  However, an explicit bind_address may
+             be used to bind the connection to a specific address.  The
+             bind_address of M-bM-^@M-^\localhostM-bM-^@M-^] indicates that the listening port be
+             bound for local use only, while an empty address or M-bM-^@M-^X*M-bM-^@M-^Y indicates
+             that the port should be available from all interfaces.
+
+     -E log_file
+             Append debug logs to log_file instead of standard error.
+
+     -e escape_char
+             Sets the escape character for sessions with a pty (default: M-bM-^@M-^X~M-bM-^@M-^Y).
+             The escape character is only recognized at the beginning of a
+             line.  The escape character followed by a dot (M-bM-^@M-^X.M-bM-^@M-^Y) closes the
+             connection; followed by control-Z suspends the connection; and
+             followed by itself sends the escape character once.  Setting the
+             character to M-bM-^@M-^\noneM-bM-^@M-^] disables any escapes and makes the session
+             fully transparent.
+
+     -F configfile
+             Specifies an alternative per-user configuration file.  If a
+             configuration file is given on the command line, the system-wide
+             configuration file (/etc/ssh/ssh_config) will be ignored.  The
+             default for the per-user configuration file is ~/.ssh/config.
+
+     -f      Requests ssh to go to background just before command execution.
+             This is useful if ssh is going to ask for passwords or
+             passphrases, but the user wants it in the background.  This
+             implies -n.  The recommended way to start X11 programs at a
+             remote site is with something like ssh -f host xterm.
+
+             If the ExitOnForwardFailure configuration option is set to M-bM-^@M-^\yesM-bM-^@M-^],
+             then a client started with -f will wait for all remote port
+             forwards to be successfully established before placing itself in
+             the background.
+
+     -G      Causes ssh to print its configuration after evaluating Host and
+             Match blocks and exit.
+
+     -g      Allows remote hosts to connect to local forwarded ports.  If used
+             on a multiplexed connection, then this option must be specified
+             on the master process.
+
+     -I pkcs11
+             Specify the PKCS#11 shared library ssh should use to communicate
+             with a PKCS#11 token providing the user's private RSA key.
+
+     -i identity_file
+             Selects a file from which the identity (private key) for public
+             key authentication is read.  The default is ~/.ssh/id_dsa,
+             ~/.ssh/id_ecdsa, ~/.ssh/id_ed25519 and ~/.ssh/id_rsa.  Identity
+             files may also be specified on a per-host basis in the
+             configuration file.  It is possible to have multiple -i options
+             (and multiple identities specified in configuration files).  If
+             no certificates have been explicitly specified by the
+             CertificateFile directive, ssh will also try to load certificate
+             information from the filename obtained by appending -cert.pub to
+             identity filenames.
+
+     -J destination
+             Connect to the target host by first making a ssh connection to
+             the jump host described by destination and then establishing a
+             TCP forwarding to the ultimate destination from there.  Multiple
+             jump hops may be specified separated by comma characters.  This
+             is a shortcut to specify a ProxyJump configuration directive.
+
+     -K      Enables GSSAPI-based authentication and forwarding (delegation)
+             of GSSAPI credentials to the server.
+
+     -k      Disables forwarding (delegation) of GSSAPI credentials to the
+             server.
+
+     -L [bind_address:]port:host:hostport
+     -L [bind_address:]port:remote_socket
+     -L local_socket:host:hostport
+     -L local_socket:remote_socket
+             Specifies that connections to the given TCP port or Unix socket
+             on the local (client) host are to be forwarded to the given host
+             and port, or Unix socket, on the remote side.  This works by
+             allocating a socket to listen to either a TCP port on the local
+             side, optionally bound to the specified bind_address, or to a
+             Unix socket.  Whenever a connection is made to the local port or
+             socket, the connection is forwarded over the secure channel, and
+             a connection is made to either host port hostport, or the Unix
+             socket remote_socket, from the remote machine.
+
+             Port forwardings can also be specified in the configuration file.
+             Only the superuser can forward privileged ports.  IPv6 addresses
+             can be specified by enclosing the address in square brackets.
+
+             By default, the local port is bound in accordance with the
+             GatewayPorts setting.  However, an explicit bind_address may be
+             used to bind the connection to a specific address.  The
+             bind_address of M-bM-^@M-^\localhostM-bM-^@M-^] indicates that the listening port be
+             bound for local use only, while an empty address or M-bM-^@M-^X*M-bM-^@M-^Y indicates
+             that the port should be available from all interfaces.
+
+     -l login_name
+             Specifies the user to log in as on the remote machine.  This also
+             may be specified on a per-host basis in the configuration file.
+
+     -M      Places the ssh client into M-bM-^@M-^\masterM-bM-^@M-^] mode for connection sharing.
+             Multiple -M options places ssh into M-bM-^@M-^\masterM-bM-^@M-^] mode but with
+             confirmation required using ssh-askpass(1) before each operation
+             that changes the multiplexing state (e.g. opening a new session).
+             Refer to the description of ControlMaster in ssh_config(5) for
+             details.
+
+     -m mac_spec
+             A comma-separated list of MAC (message authentication code)
+             algorithms, specified in order of preference.  See the MACs
+             keyword for more information.
+
+     -N      Do not execute a remote command.  This is useful for just
+             forwarding ports.
+
+     -n      Redirects stdin from /dev/null (actually, prevents reading from
+             stdin).  This must be used when ssh is run in the background.  A
+             common trick is to use this to run X11 programs on a remote
+             machine.  For example, ssh -n shadows.cs.hut.fi emacs & will
+             start an emacs on shadows.cs.hut.fi, and the X11 connection will
+             be automatically forwarded over an encrypted channel.  The ssh
+             program will be put in the background.  (This does not work if
+             ssh needs to ask for a password or passphrase; see also the -f
+             option.)
+
+     -O ctl_cmd
+             Control an active connection multiplexing master process.  When
+             the -O option is specified, the ctl_cmd argument is interpreted
+             and passed to the master process.  Valid commands are: M-bM-^@M-^\checkM-bM-^@M-^]
+             (check that the master process is running), M-bM-^@M-^\forwardM-bM-^@M-^] (request
+             forwardings without command execution), M-bM-^@M-^\cancelM-bM-^@M-^] (cancel
+             forwardings), M-bM-^@M-^\exitM-bM-^@M-^] (request the master to exit), and M-bM-^@M-^\stopM-bM-^@M-^]
+             (request the master to stop accepting further multiplexing
+             requests).
+
+     -o option
+             Can be used to give options in the format used in the
+             configuration file.  This is useful for specifying options for
+             which there is no separate command-line flag.  For full details
+             of the options listed below, and their possible values, see
+             ssh_config(5).

+
+     -Q query_option

+             symmetric ciphers), cipher-auth (supported symmetric ciphers that

+             codes), kex (key exchange algorithms), key (key types), key-cert
+             (certificate key types), key-plain (non-certificate key types),
+             protocol-version (supported SSH protocol versions), and sig
+             (supported signature algorithms).
+
+     -q      Quiet mode.  Causes most warning and diagnostic messages to be
+             suppressed.
+
+     -R [bind_address:]port:host:hostport
+     -R [bind_address:]port:local_socket
+     -R remote_socket:host:hostport
+     -R remote_socket:local_socket
+     -R [bind_address:]port
+             Specifies that connections to the given TCP port or Unix socket
+             on the remote (server) host are to be forwarded to the local
+             side.
+
+             This works by allocating a socket to listen to either a TCP port
+             or to a Unix socket on the remote side.  Whenever a connection is
+             made to this port or Unix socket, the connection is forwarded
+             over the secure channel, and a connection is made from the local
+             machine to either an explicit destination specified by host port
+             hostport, or local_socket, or, if no explicit destination was
+             specified, ssh will act as a SOCKS 4/5 proxy and forward
+             connections to the destinations requested by the remote SOCKS
+             client.
+
+             Port forwardings can also be specified in the configuration file.
+             Privileged ports can be forwarded only when logging in as root on
+             the remote machine.  IPv6 addresses can be specified by enclosing
+             the address in square brackets.
+
+             By default, TCP listening sockets on the server will be bound to
+             the loopback interface only.  This may be overridden by
+             specifying a bind_address.  An empty bind_address, or the address
+             M-bM-^@M-^X*M-bM-^@M-^Y, indicates that the remote socket should listen on all
+             interfaces.  Specifying a remote bind_address will only succeed
+             if the server's GatewayPorts option is enabled (see
+             sshd_config(5)).
+
+             If the port argument is M-bM-^@M-^X0M-bM-^@M-^Y, the listen port will be dynamically
+             allocated on the server and reported to the client at run time.
+             When used together with -O forward the allocated port will be
+             printed to the standard output.
+
+     -S ctl_path
+             Specifies the location of a control socket for connection
+             sharing, or the string M-bM-^@M-^\noneM-bM-^@M-^] to disable connection sharing.
+             Refer to the description of ControlPath and ControlMaster in
+             ssh_config(5) for details.
+
+     -s      May be used to request invocation of a subsystem on the remote
+             system.  Subsystems facilitate the use of SSH as a secure
+             transport for other applications (e.g. sftp(1)).  The subsystem
+             is specified as the remote command.
+
+     -T      Disable pseudo-terminal allocation.
+
+     -t      Force pseudo-terminal allocation.  This can be used to execute
+             arbitrary screen-based programs on a remote machine, which can be
+             very useful, e.g. when implementing menu services.  Multiple -t
+             options force tty allocation, even if ssh has no local tty.
+
+     -V      Display the version number and exit.
+
+     -v      Verbose mode.  Causes ssh to print debugging messages about its
+             progress.  This is helpful in debugging connection,
+             authentication, and configuration problems.  Multiple -v options
+             increase the verbosity.  The maximum is 3.
+
+     -W host:port
+             Requests that standard input and output on the client be
+             forwarded to host on port over the secure channel.  Implies -N,
+             -T, ExitOnForwardFailure and ClearAllForwardings, though these
+             can be overridden in the configuration file or using -o command
+             line options.
+
+     -w local_tun[:remote_tun]
+             Requests tunnel device forwarding with the specified tun(4)
+             devices between the client (local_tun) and the server
+             (remote_tun).
+
+             The devices may be specified by numerical ID or the keyword
+             M-bM-^@M-^\anyM-bM-^@M-^], which uses the next available tunnel device.  If
+             remote_tun is not specified, it defaults to M-bM-^@M-^\anyM-bM-^@M-^].  See also the
+             Tunnel and TunnelDevice directives in ssh_config(5).
+
+             If the Tunnel directive is unset, it will be set to the default
+             tunnel mode, which is M-bM-^@M-^\point-to-pointM-bM-^@M-^].  If a different Tunnel
+             forwarding mode it desired, then it should be specified before
+             -w.
+
+     -X      Enables X11 forwarding.  This can also be specified on a per-host
+             basis in a configuration file.
+
+             X11 forwarding should be enabled with caution.  Users with the
+             ability to bypass file permissions on the remote host (for the
+             user's X authorization database) can access the local X11 display
+             through the forwarded connection.  An attacker may then be able
+             to perform activities such as keystroke monitoring.
+
+             For this reason, X11 forwarding is subjected to X11 SECURITY
+             extension restrictions by default.  Please refer to the ssh -Y
+             option and the ForwardX11Trusted directive in ssh_config(5) for
+             more information.
+
+     -x      Disables X11 forwarding.
+
+     -Y      Enables trusted X11 forwarding.  Trusted X11 forwardings are not
+             subjected to the X11 SECURITY extension controls.
+
+     -y      Send log information using the syslog(3) system module.  By
+             default this information is sent to stderr.
+
+     ssh may additionally obtain configuration data from a per-user
+     configuration file and a system-wide configuration file.  The file format
+     and configuration options are described in ssh_config(5).
+
+AUTHENTICATION
+     The OpenSSH SSH client supports SSH protocol 2.
+
+     The methods available for authentication are: GSSAPI-based
+     authentication, host-based authentication, public key authentication,
+     challenge-response authentication, and password authentication.
+     Authentication methods are tried in the order specified above, though
+     PreferredAuthentications can be used to change the default order.
+
+     Host-based authentication works as follows: If the machine the user logs
+     in from is listed in /etc/hosts.equiv or /etc/shosts.equiv on the remote
+     machine, and the user names are the same on both sides, or if the files
+     ~/.rhosts or ~/.shosts exist in the user's home directory on the remote
+     machine and contain a line containing the name of the client machine and
+     the name of the user on that machine, the user is considered for login.
+     Additionally, the server must be able to verify the client's host key
+     (see the description of /etc/ssh/ssh_known_hosts and ~/.ssh/known_hosts,
+     below) for login to be permitted.  This authentication method closes
+     security holes due to IP spoofing, DNS spoofing, and routing spoofing.
+     [Note to the administrator: /etc/hosts.equiv, ~/.rhosts, and the
+     rlogin/rsh protocol in general, are inherently insecure and should be
+     disabled if security is desired.]
+
+     Public key authentication works as follows: The scheme is based on
+     public-key cryptography, using cryptosystems where encryption and
+     decryption are done using separate keys, and it is unfeasible to derive
+     the decryption key from the encryption key.  The idea is that each user
+     creates a public/private key pair for authentication purposes.  The
+     server knows the public key, and only the user knows the private key.
+     ssh implements public key authentication protocol automatically, using
+     one of the DSA, ECDSA, Ed25519 or RSA algorithms.  The HISTORY section of
+     ssl(8) contains a brief discussion of the DSA and RSA algorithms.
+
+     The file ~/.ssh/authorized_keys lists the public keys that are permitted
+     for logging in.  When the user logs in, the ssh program tells the server
+     which key pair it would like to use for authentication.  The client
+     proves that it has access to the private key and the server checks that
+     the corresponding public key is authorized to accept the account.
+
+     The server may inform the client of errors that prevented public key
+     authentication from succeeding after authentication completes using a
+     different method.  These may be viewed by increasing the LogLevel to
+     DEBUG or higher (e.g. by using the -v flag).
+
+     The user creates his/her key pair by running ssh-keygen(1).  This stores
+     the private key in ~/.ssh/id_dsa (DSA), ~/.ssh/id_ecdsa (ECDSA),
+     ~/.ssh/id_ed25519 (Ed25519), or ~/.ssh/id_rsa (RSA) and stores the public
+     key in ~/.ssh/id_dsa.pub (DSA), ~/.ssh/id_ecdsa.pub (ECDSA),
+     ~/.ssh/id_ed25519.pub (Ed25519), or ~/.ssh/id_rsa.pub (RSA) in the user's
+     home directory.  The user should then copy the public key to
+     ~/.ssh/authorized_keys in his/her home directory on the remote machine.
+     The authorized_keys file corresponds to the conventional ~/.rhosts file,
+     and has one key per line, though the lines can be very long.  After this,
+     the user can log in without giving the password.
+
+     A variation on public key authentication is available in the form of
+     certificate authentication: instead of a set of public/private keys,
+     signed certificates are used.  This has the advantage that a single
+     trusted certification authority can be used in place of many
+     public/private keys.  See the CERTIFICATES section of ssh-keygen(1) for
+     more information.
+
+     The most convenient way to use public key or certificate authentication
+     may be with an authentication agent.  See ssh-agent(1) and (optionally)
+     the AddKeysToAgent directive in ssh_config(5) for more information.
+
+     Challenge-response authentication works as follows: The server sends an
+     arbitrary "challenge" text, and prompts for a response.  Examples of
+     challenge-response authentication include BSD Authentication (see
+     login.conf(5)) and PAM (some non-OpenBSD systems).
+
+     Finally, if other authentication methods fail, ssh prompts the user for a
+     password.  The password is sent to the remote host for checking; however,
+     since all communications are encrypted, the password cannot be seen by
+     someone listening on the network.
+
+     ssh automatically maintains and checks a database containing
+     identification for all hosts it has ever been used with.  Host keys are
+     stored in ~/.ssh/known_hosts in the user's home directory.  Additionally,
+     the file /etc/ssh/ssh_known_hosts is automatically checked for known
+     hosts.  Any new hosts are automatically added to the user's file.  If a
+     host's identification ever changes, ssh warns about this and disables
+     password authentication to prevent server spoofing or man-in-the-middle
+     attacks, which could otherwise be used to circumvent the encryption.  The
+     StrictHostKeyChecking option can be used to control logins to machines
+     whose host key is not known or has changed.
+
+     When the user's identity has been accepted by the server, the server
+     either executes the given command in a non-interactive session or, if no
+     command has been specified, logs into the machine and gives the user a
+     normal shell as an interactive session.  All communication with the
+     remote command or shell will be automatically encrypted.
+
+     If an interactive session is requested ssh by default will only request a
+     pseudo-terminal (pty) for interactive sessions when the client has one.
+     The flags -T and -t can be used to override this behaviour.
+
+     If a pseudo-terminal has been allocated the user may use the escape
+     characters noted below.
+
+     If no pseudo-terminal has been allocated, the session is transparent and
+     can be used to reliably transfer binary data.  On most systems, setting
+     the escape character to M-bM-^@M-^\noneM-bM-^@M-^] will also make the session transparent
+     even if a tty is used.
+
+     The session terminates when the command or shell on the remote machine
+     exits and all X11 and TCP connections have been closed.
+
+ESCAPE CHARACTERS
+     When a pseudo-terminal has been requested, ssh supports a number of
+     functions through the use of an escape character.
+
+     A single tilde character can be sent as ~~ or by following the tilde by a
+     character other than those described below.  The escape character must
+     always follow a newline to be interpreted as special.  The escape
+     character can be changed in configuration files using the EscapeChar
+     configuration directive or on the command line by the -e option.
+
+     The supported escapes (assuming the default M-bM-^@M-^X~M-bM-^@M-^Y) are:
+
+     ~.      Disconnect.
+
+     ~^Z     Background ssh.
+
+     ~#      List forwarded connections.
+
+     ~&      Background ssh at logout when waiting for forwarded connection /
+             X11 sessions to terminate.
+
+     ~?      Display a list of escape characters.
+
+     ~B      Send a BREAK to the remote system (only useful if the peer
+             supports it).
+
+     ~C      Open command line.  Currently this allows the addition of port
+             forwardings using the -L, -R and -D options (see above).  It also
+             allows the cancellation of existing port-forwardings with
+             -KL[bind_address:]port for local, -KR[bind_address:]port for
+             remote and -KD[bind_address:]port for dynamic port-forwardings.
+             !command allows the user to execute a local command if the
+             PermitLocalCommand option is enabled in ssh_config(5).  Basic
+             help is available, using the -h option.
+
+     ~R      Request rekeying of the connection (only useful if the peer
+             supports it).
+
+     ~V      Decrease the verbosity (LogLevel) when errors are being written
+             to stderr.
+
+     ~v      Increase the verbosity (LogLevel) when errors are being written
+             to stderr.
+
+TCP FORWARDING
+     Forwarding of arbitrary TCP connections over the secure channel can be
+     specified either on the command line or in a configuration file.  One
+     possible application of TCP forwarding is a secure connection to a mail
+     server; another is going through firewalls.
+
+     In the example below, we look at encrypting communication between an IRC
+     client and server, even though the IRC server does not directly support
+     encrypted communications.  This works as follows: the user connects to
+     the remote host using ssh, specifying a port to be used to forward
+     connections to the remote server.  After that it is possible to start the
+     service which is to be encrypted on the client machine, connecting to the
+     same local port, and ssh will encrypt and forward the connection.
+
+     The following example tunnels an IRC session from client machine
+     M-bM-^@M-^\127.0.0.1M-bM-^@M-^] (localhost) to remote server M-bM-^@M-^\server.example.comM-bM-^@M-^]:
+
+         $ ssh -f -L 1234:localhost:6667 server.example.com sleep 10
+         $ irc -c '#users' -p 1234 pinky 127.0.0.1
+
+     This tunnels a connection to IRC server M-bM-^@M-^\server.example.comM-bM-^@M-^], joining
+     channel M-bM-^@M-^\#usersM-bM-^@M-^], nickname M-bM-^@M-^\pinkyM-bM-^@M-^], using port 1234.  It doesn't matter
+     which port is used, as long as it's greater than 1023 (remember, only
+     root can open sockets on privileged ports) and doesn't conflict with any
+     ports already in use.  The connection is forwarded to port 6667 on the
+     remote server, since that's the standard port for IRC services.
+
+     The -f option backgrounds ssh and the remote command M-bM-^@M-^\sleep 10M-bM-^@M-^] is
+     specified to allow an amount of time (10 seconds, in the example) to
+     start the service which is to be tunnelled.  If no connections are made
+     within the time specified, ssh will exit.
+
+X11 FORWARDING
+     If the ForwardX11 variable is set to M-bM-^@M-^\yesM-bM-^@M-^] (or see the description of the
+     -X, -x, and -Y options above) and the user is using X11 (the DISPLAY
+     environment variable is set), the connection to the X11 display is
+     automatically forwarded to the remote side in such a way that any X11
+     programs started from the shell (or command) will go through the
+     encrypted channel, and the connection to the real X server will be made
+     from the local machine.  The user should not manually set DISPLAY.
+     Forwarding of X11 connections can be configured on the command line or in
+     configuration files.
+
+     The DISPLAY value set by ssh will point to the server machine, but with a
+     display number greater than zero.  This is normal, and happens because
+     ssh creates a M-bM-^@M-^\proxyM-bM-^@M-^] X server on the server machine for forwarding the
+     connections over the encrypted channel.
+
+     ssh will also automatically set up Xauthority data on the server machine.
+     For this purpose, it will generate a random authorization cookie, store
+     it in Xauthority on the server, and verify that any forwarded connections
+     carry this cookie and replace it by the real cookie when the connection
+     is opened.  The real authentication cookie is never sent to the server
+     machine (and no cookies are sent in the plain).
+
+     If the ForwardAgent variable is set to M-bM-^@M-^\yesM-bM-^@M-^] (or see the description of
+     the -A and -a options above) and the user is using an authentication
+     agent, the connection to the agent is automatically forwarded to the
+     remote side.
+
+VERIFYING HOST KEYS
+     When connecting to a server for the first time, a fingerprint of the
+     server's public key is presented to the user (unless the option
+     StrictHostKeyChecking has been disabled).  Fingerprints can be determined
+     using ssh-keygen(1):
+
+           $ ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key
+
+     If the fingerprint is already known, it can be matched and the key can be
+     accepted or rejected.  If only legacy (MD5) fingerprints for the server
+     are available, the ssh-keygen(1) -E option may be used to downgrade the
+     fingerprint algorithm to match.
+
+     Because of the difficulty of comparing host keys just by looking at
+     fingerprint strings, there is also support to compare host keys visually,
+     using random art.  By setting the VisualHostKey option to M-bM-^@M-^\yesM-bM-^@M-^], a small
+     ASCII graphic gets displayed on every login to a server, no matter if the
+     session itself is interactive or not.  By learning the pattern a known
+     server produces, a user can easily find out that the host key has changed
+     when a completely different pattern is displayed.  Because these patterns
+     are not unambiguous however, a pattern that looks similar to the pattern
+     remembered only gives a good probability that the host key is the same,
+     not guaranteed proof.
+
+     To get a listing of the fingerprints along with their random art for all
+     known hosts, the following command line can be used:
+
+           $ ssh-keygen -lv -f ~/.ssh/known_hosts
+
+     If the fingerprint is unknown, an alternative method of verification is
+     available: SSH fingerprints verified by DNS.  An additional resource
+     record (RR), SSHFP, is added to a zonefile and the connecting client is
+     able to match the fingerprint with that of the key presented.
+
+     In this example, we are connecting a client to a server,
+     M-bM-^@M-^\host.example.comM-bM-^@M-^].  The SSHFP resource records should first be added to
+     the zonefile for host.example.com:
+
+           $ ssh-keygen -r host.example.com.
+
+     The output lines will have to be added to the zonefile.  To check that
+     the zone is answering fingerprint queries:
+
+           $ dig -t SSHFP host.example.com
+
+     Finally the client connects:
+
+           $ ssh -o "VerifyHostKeyDNS ask" host.example.com
+           [...]
+           Matching host key fingerprint found in DNS.
+           Are you sure you want to continue connecting (yes/no)?
+
+     See the VerifyHostKeyDNS option in ssh_config(5) for more information.
+
+SSH-BASED VIRTUAL PRIVATE NETWORKS
+     ssh contains support for Virtual Private Network (VPN) tunnelling using
+     the tun(4) network pseudo-device, allowing two networks to be joined
+     securely.  The sshd_config(5) configuration option PermitTunnel controls
+     whether the server supports this, and at what level (layer 2 or 3
+     traffic).
+
+     The following example would connect client network 10.0.50.0/24 with
+     remote network 10.0.99.0/24 using a point-to-point connection from
+     10.1.1.1 to 10.1.1.2, provided that the SSH server running on the gateway
+     to the remote network, at 192.168.1.15, allows it.
+
+     On the client:
+
+           # ssh -f -w 0:1 192.168.1.15 true
+           # ifconfig tun0 10.1.1.1 10.1.1.2 netmask 255.255.255.252
+           # route add 10.0.99.0/24 10.1.1.2
+
+     On the server:
+
+           # ifconfig tun1 10.1.1.2 10.1.1.1 netmask 255.255.255.252
+           # route add 10.0.50.0/24 10.1.1.1
+
+     Client access may be more finely tuned via the /root/.ssh/authorized_keys
+     file (see below) and the PermitRootLogin server option.  The following
+     entry would permit connections on tun(4) device 1 from user M-bM-^@M-^\janeM-bM-^@M-^] and on
+     tun device 2 from user M-bM-^@M-^\johnM-bM-^@M-^], if PermitRootLogin is set to
+     M-bM-^@M-^\forced-commands-onlyM-bM-^@M-^]:
+
+       tunnel="1",command="sh /etc/netstart tun1" ssh-rsa ... jane
+       tunnel="2",command="sh /etc/netstart tun2" ssh-rsa ... john
+
+     Since an SSH-based setup entails a fair amount of overhead, it may be
+     more suited to temporary setups, such as for wireless VPNs.  More
+     permanent VPNs are better provided by tools such as ipsecctl(8) and
+     isakmpd(8).
+
+ENVIRONMENT
+     ssh will normally set the following environment variables:
+
+     DISPLAY               The DISPLAY variable indicates the location of the
+                           X11 server.  It is automatically set by ssh to
+                           point to a value of the form M-bM-^@M-^\hostname:nM-bM-^@M-^], where
+                           M-bM-^@M-^\hostnameM-bM-^@M-^] indicates the host where the shell runs,
+                           and M-bM-^@M-^XnM-bM-^@M-^Y is an integer M-bM-^IM-% 1.  ssh uses this special
+                           value to forward X11 connections over the secure
+                           channel.  The user should normally not set DISPLAY
+                           explicitly, as that will render the X11 connection
+                           insecure (and will require the user to manually
+                           copy any required authorization cookies).
+
+     HOME                  Set to the path of the user's home directory.
+
+     LOGNAME               Synonym for USER; set for compatibility with
+                           systems that use this variable.
+
+     MAIL                  Set to the path of the user's mailbox.
+
+     PATH                  Set to the default PATH, as specified when
+                           compiling ssh.
+
+     SSH_ASKPASS           If ssh needs a passphrase, it will read the
+                           passphrase from the current terminal if it was run
+                           from a terminal.  If ssh does not have a terminal
+                           associated with it but DISPLAY and SSH_ASKPASS are
+                           set, it will execute the program specified by
+                           SSH_ASKPASS and open an X11 window to read the
+                           passphrase.  This is particularly useful when
+                           calling ssh from a .xsession or related script.
+                           (Note that on some machines it may be necessary to
+                           redirect the input from /dev/null to make this
+                           work.)
+
+     SSH_AUTH_SOCK         Identifies the path of a UNIX-domain socket used to
+                           communicate with the agent.
+
+     SSH_CONNECTION        Identifies the client and server ends of the
+                           connection.  The variable contains four space-
+                           separated values: client IP address, client port
+                           number, server IP address, and server port number.
+
+     SSH_ORIGINAL_COMMAND  This variable contains the original command line if
+                           a forced command is executed.  It can be used to
+                           extract the original arguments.
+
+     SSH_TTY               This is set to the name of the tty (path to the
+                           device) associated with the current shell or
+                           command.  If the current session has no tty, this
+                           variable is not set.
+
+     SSH_TUNNEL            Optionally set by sshd(8) to contain the interface
+                           names assigned if tunnel forwarding was requested
+                           by the client.
+
+     SSH_USER_AUTH         Optionally set by sshd(8), this variable may
+                           contain a pathname to a file that lists the
+                           authentication methods successfully used when the
+                           session was established, including any public keys
+                           that were used.
+
+     TZ                    This variable is set to indicate the present time
+                           zone if it was set when the daemon was started
+                           (i.e. the daemon passes the value on to new
+                           connections).
+
+     USER                  Set to the name of the user logging in.
+
+     Additionally, ssh reads ~/.ssh/environment, and adds lines of the format
+     M-bM-^@M-^\VARNAME=valueM-bM-^@M-^] to the environment if the file exists and users are
+     allowed to change their environment.  For more information, see the
+     PermitUserEnvironment option in sshd_config(5).
+
+FILES
+     ~/.rhosts
+             This file is used for host-based authentication (see above).  On
+             some machines this file may need to be world-readable if the
+             user's home directory is on an NFS partition, because sshd(8)
+             reads it as root.  Additionally, this file must be owned by the
+             user, and must not have write permissions for anyone else.  The
+             recommended permission for most machines is read/write for the
+             user, and not accessible by others.
+
+     ~/.shosts
+             This file is used in exactly the same way as .rhosts, but allows
+             host-based authentication without permitting login with
+             rlogin/rsh.
+
+     ~/.ssh/
+             This directory is the default location for all user-specific
+             configuration and authentication information.  There is no
+             general requirement to keep the entire contents of this directory
+             secret, but the recommended permissions are read/write/execute
+             for the user, and not accessible by others.
+
+     ~/.ssh/authorized_keys
+             Lists the public keys (DSA, ECDSA, Ed25519, RSA) that can be used
+             for logging in as this user.  The format of this file is
+             described in the sshd(8) manual page.  This file is not highly
+             sensitive, but the recommended permissions are read/write for the
+             user, and not accessible by others.
+
+     ~/.ssh/config
+             This is the per-user configuration file.  The file format and
+             configuration options are described in ssh_config(5).  Because of
+             the potential for abuse, this file must have strict permissions:
+             read/write for the user, and not writable by others.
+
+     ~/.ssh/environment
+             Contains additional definitions for environment variables; see
+             ENVIRONMENT, above.
+
+     ~/.ssh/id_dsa
+     ~/.ssh/id_ecdsa
+     ~/.ssh/id_ed25519
+     ~/.ssh/id_rsa
+             Contains the private key for authentication.  These files contain
+             sensitive data and should be readable by the user but not
+             accessible by others (read/write/execute).  ssh will simply
+             ignore a private key file if it is accessible by others.  It is
+             possible to specify a passphrase when generating the key which
+             will be used to encrypt the sensitive part of this file using
+             AES-128.
+
+     ~/.ssh/id_dsa.pub
+     ~/.ssh/id_ecdsa.pub
+     ~/.ssh/id_ed25519.pub
+     ~/.ssh/id_rsa.pub
+             Contains the public key for authentication.  These files are not
+             sensitive and can (but need not) be readable by anyone.
+
+     ~/.ssh/known_hosts
+             Contains a list of host keys for all hosts the user has logged
+             into that are not already in the systemwide list of known host
+             keys.  See sshd(8) for further details of the format of this
+             file.
+
+     ~/.ssh/rc
+             Commands in this file are executed by ssh when the user logs in,
+             just before the user's shell (or command) is started.  See the
+             sshd(8) manual page for more information.
+
+     /etc/hosts.equiv
+             This file is for host-based authentication (see above).  It
+             should only be writable by root.
+
+     /etc/shosts.equiv
+             This file is used in exactly the same way as hosts.equiv, but
+             allows host-based authentication without permitting login with
+             rlogin/rsh.
+
+     /etc/ssh/ssh_config
+             Systemwide configuration file.  The file format and configuration
+             options are described in ssh_config(5).
+
+     /etc/ssh/ssh_host_key
+     /etc/ssh/ssh_host_dsa_key
+     /etc/ssh/ssh_host_ecdsa_key
+     /etc/ssh/ssh_host_ed25519_key
+     /etc/ssh/ssh_host_rsa_key
+             These files contain the private parts of the host keys and are
+             used for host-based authentication.
+
+     /etc/ssh/ssh_known_hosts
+             Systemwide list of known host keys.  This file should be prepared
+             by the system administrator to contain the public host keys of
+             all machines in the organization.  It should be world-readable.
+             See sshd(8) for further details of the format of this file.
+
+     /etc/ssh/sshrc
+             Commands in this file are executed by ssh when the user logs in,
+             just before the user's shell (or command) is started.  See the
+             sshd(8) manual page for more information.
+
+EXIT STATUS
+     ssh exits with the exit status of the remote command or with 255 if an
+     error occurred.

+SSH_CONFIG(5)                 File Formats Manual                SSH_CONFIG(5)
+
+NAME
+     ssh_config M-bM-^@M-^S OpenSSH SSH client configuration files
+
+DESCRIPTION
+     ssh(1) obtains configuration data from the following sources in the
+     following order:
+
+           1.   command-line options
+           2.   user's configuration file (~/.ssh/config)
+           3.   system-wide configuration file (/etc/ssh/ssh_config)
+
+     For each parameter, the first obtained value will be used.  The
+     configuration files contain sections separated by Host specifications,
+     and that section is only applied for hosts that match one of the patterns
+     given in the specification.  The matched host name is usually the one
+     given on the command line (see the CanonicalizeHostname option for
+     exceptions).
+
+     Since the first obtained value for each parameter is used, more host-
+     specific declarations should be given near the beginning of the file, and
+     general defaults at the end.
+
+     The file contains keyword-argument pairs, one per line.  Lines starting
+     with M-bM-^@M-^X#M-bM-^@M-^Y and empty lines are interpreted as comments.  Arguments may
+     optionally be enclosed in double quotes (") in order to represent
+     arguments containing spaces.  Configuration options may be separated by
+     whitespace or optional whitespace and exactly one M-bM-^@M-^X=M-bM-^@M-^Y; the latter format
+     is useful to avoid the need to quote whitespace when specifying
+     configuration options using the ssh, scp, and sftp -o option.
+
+     The possible keywords and their meanings are as follows (note that
+     keywords are case-insensitive and arguments are case-sensitive):
+
+     Host    Restricts the following declarations (up to the next Host or
+             Match keyword) to be only for those hosts that match one of the
+             patterns given after the keyword.  If more than one pattern is
+             provided, they should be separated by whitespace.  A single M-bM-^@M-^X*M-bM-^@M-^Y
+             as a pattern can be used to provide global defaults for all
+             hosts.  The host is usually the hostname argument given on the
+             command line (see the CanonicalizeHostname keyword for
+             exceptions).
+
+             A pattern entry may be negated by prefixing it with an
+             exclamation mark (M-bM-^@M-^X!M-bM-^@M-^Y).  If a negated entry is matched, then the
+             Host entry is ignored, regardless of whether any other patterns
+             on the line match.  Negated matches are therefore useful to
+             provide exceptions for wildcard matches.
+
+             See PATTERNS for more information on patterns.
+
+     Match   Restricts the following declarations (up to the next Host or
+             Match keyword) to be used only when the conditions following the
+             Match keyword are satisfied.  Match conditions are specified
+             using one or more criteria or the single token all which always
+             matches.  The available criteria keywords are: canonical, exec,
+             host, originalhost, user, and localuser.  The all criteria must
+             appear alone or immediately after canonical.  Other criteria may
+             be combined arbitrarily.  All criteria but all and canonical
+             require an argument.  Criteria may be negated by prepending an
+             exclamation mark (M-bM-^@M-^X!M-bM-^@M-^Y).
+
+             The canonical keyword matches only when the configuration file is
+             being re-parsed after hostname canonicalization (see the
+             CanonicalizeHostname option.)  This may be useful to specify
+             conditions that work with canonical host names only.  The exec
+             keyword executes the specified command under the user's shell.
+             If the command returns a zero exit status then the condition is
+             considered true.  Commands containing whitespace characters must
+             be quoted.  Arguments to exec accept the tokens described in the
+             TOKENS section.
+
+             The other keywords' criteria must be single entries or comma-
+             separated lists and may use the wildcard and negation operators
+             described in the PATTERNS section.  The criteria for the host
+             keyword are matched against the target hostname, after any
+             substitution by the Hostname or CanonicalizeHostname options.
+             The originalhost keyword matches against the hostname as it was
+             specified on the command-line.  The user keyword matches against
+             the target username on the remote host.  The localuser keyword
+             matches against the name of the local user running ssh(1) (this
+             keyword may be useful in system-wide ssh_config files).
+
+     AddKeysToAgent
+             Specifies whether keys should be automatically added to a running
+             ssh-agent(1).  If this option is set to yes and a key is loaded
+             from a file, the key and its passphrase are added to the agent
+             with the default lifetime, as if by ssh-add(1).  If this option
+             is set to ask, ssh(1) will require confirmation using the
+             SSH_ASKPASS program before adding a key (see ssh-add(1) for
+             details).  If this option is set to confirm, each use of the key
+             must be confirmed, as if the -c option was specified to
+             ssh-add(1).  If this option is set to no, no keys are added to
+             the agent.  The argument must be yes, confirm, ask, or no (the
+             default).
+
+     AddressFamily
+             Specifies which address family to use when connecting.  Valid
+             arguments are any (the default), inet (use IPv4 only), or inet6
+             (use IPv6 only).
+
+     BatchMode
+             If set to yes, passphrase/password querying will be disabled.
+             This option is useful in scripts and other batch jobs where no
+             user is present to supply the password.  The argument must be yes
+             or no (the default).
+
+     BindAddress
+             Use the specified address on the local machine as the source
+             address of the connection.  Only useful on systems with more than
+             one address.
+
+     BindInterface
+             Use the address of the specified interface on the local machine
+             as the source address of the connection.
+
+     CanonicalDomains
+             When CanonicalizeHostname is enabled, this option specifies the
+             list of domain suffixes in which to search for the specified
+             destination host.
+
+     CanonicalizeFallbackLocal
+             Specifies whether to fail with an error when hostname
+             canonicalization fails.  The default, yes, will attempt to look
+             up the unqualified hostname using the system resolver's search
+             rules.  A value of no will cause ssh(1) to fail instantly if
+             CanonicalizeHostname is enabled and the target hostname cannot be
+             found in any of the domains specified by CanonicalDomains.
+
+     CanonicalizeHostname
+             Controls whether explicit hostname canonicalization is performed.
+             The default, no, is not to perform any name rewriting and let the
+             system resolver handle all hostname lookups.  If set to yes then,
+             for connections that do not use a ProxyCommand or ProxyJump,
+             ssh(1) will attempt to canonicalize the hostname specified on the
+             command line using the CanonicalDomains suffixes and
+             CanonicalizePermittedCNAMEs rules.  If CanonicalizeHostname is
+             set to always, then canonicalization is applied to proxied
+             connections too.
+
+             If this option is enabled, then the configuration files are
+             processed again using the new target name to pick up any new
+             configuration in matching Host and Match stanzas.
+
+     CanonicalizeMaxDots
+             Specifies the maximum number of dot characters in a hostname
+             before canonicalization is disabled.  The default, 1, allows a
+             single dot (i.e. hostname.subdomain).
+
+     CanonicalizePermittedCNAMEs
+             Specifies rules to determine whether CNAMEs should be followed
+             when canonicalizing hostnames.  The rules consist of one or more
+             arguments of source_domain_list:target_domain_list, where
+             source_domain_list is a pattern-list of domains that may follow
+             CNAMEs in canonicalization, and target_domain_list is a pattern-
+             list of domains that they may resolve to.
+
+             For example, "*.a.example.com:*.b.example.com,*.c.example.com"
+             will allow hostnames matching "*.a.example.com" to be
+             canonicalized to names in the "*.b.example.com" or
+             "*.c.example.com" domains.
+
+     CASignatureAlgorithms
+             Specifies which algorithms are allowed for signing of
+             certificates by certificate authorities (CAs).  The default is:
+
+                   ecdsa-sha2-nistp256.ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
+                   ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa
+
+             ssh(1) will not accept host certificates signed using algorithms
+             other than those specified.
+
+     CertificateFile
+             Specifies a file from which the user's certificate is read.  A
+             corresponding private key must be provided separately in order to
+             use this certificate either from an IdentityFile directive or -i
+             flag to ssh(1), via ssh-agent(1), or via a PKCS11Provider.
+
+             Arguments to CertificateFile may use the tilde syntax to refer to
+             a user's home directory or the tokens described in the TOKENS
+             section.
+
+             It is possible to have multiple certificate files specified in
+             configuration files; these certificates will be tried in
+             sequence.  Multiple CertificateFile directives will add to the
+             list of certificates used for authentication.
+
+     ChallengeResponseAuthentication
+             Specifies whether to use challenge-response authentication.  The
+             argument to this keyword must be yes (the default) or no.
+
+     CheckHostIP
+             If set to yes (the default), ssh(1) will additionally check the
+             host IP address in the known_hosts file.  This allows it to
+             detect if a host key changed due to DNS spoofing and will add
+             addresses of destination hosts to ~/.ssh/known_hosts in the
+             process, regardless of the setting of StrictHostKeyChecking.  If
+             the option is set to no, the check will not be executed.
+
+     Ciphers
+             Specifies the ciphers allowed and their order of preference.
+             Multiple ciphers must be comma-separated.  If the specified value
+             begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified ciphers will be
+             appended to the default set instead of replacing them.  If the
+             specified value begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified
+             ciphers (including wildcards) will be removed from the default
+             set instead of replacing them.
+
+             The supported ciphers are:
+
+                   3des-cbc
+                   aes128-cbc
+                   aes192-cbc
+                   aes256-cbc
+                   aes128-ctr
+                   aes192-ctr
+                   aes256-ctr
+                   aes128-gcm@openssh.com
+                   aes256-gcm@openssh.com
+                   chacha20-poly1305@openssh.com
+
+             The default is:
+
+                   chacha20-poly1305@openssh.com,
+                   aes128-ctr,aes192-ctr,aes256-ctr,
+                   aes128-gcm@openssh.com,aes256-gcm@openssh.com
+
+             The list of available ciphers may also be obtained using "ssh -Q
+             cipher".
+
+     ClearAllForwardings
+             Specifies that all local, remote, and dynamic port forwardings
+             specified in the configuration files or on the command line be
+             cleared.  This option is primarily useful when used from the
+             ssh(1) command line to clear port forwardings set in
+             configuration files, and is automatically set by scp(1) and
+             sftp(1).  The argument must be yes or no (the default).
+
+     Compression
+             Specifies whether to use compression.  The argument must be yes
+             or no (the default).
+
+     ConnectionAttempts
+             Specifies the number of tries (one per second) to make before
+             exiting.  The argument must be an integer.  This may be useful in
+             scripts if the connection sometimes fails.  The default is 1.
+
+     ConnectTimeout
+             Specifies the timeout (in seconds) used when connecting to the
+             SSH server, instead of using the default system TCP timeout.
+             This value is used only when the target is down or really
+             unreachable, not when it refuses the connection.
+
+     ControlMaster
+             Enables the sharing of multiple sessions over a single network
+             connection.  When set to yes, ssh(1) will listen for connections
+             on a control socket specified using the ControlPath argument.
+             Additional sessions can connect to this socket using the same
+             ControlPath with ControlMaster set to no (the default).  These
+             sessions will try to reuse the master instance's network
+             connection rather than initiating new ones, but will fall back to
+             connecting normally if the control socket does not exist, or is
+             not listening.
+
+             Setting this to ask will cause ssh(1) to listen for control
+             connections, but require confirmation using ssh-askpass(1).  If
+             the ControlPath cannot be opened, ssh(1) will continue without
+             connecting to a master instance.
+
+             X11 and ssh-agent(1) forwarding is supported over these
+             multiplexed connections, however the display and agent forwarded
+             will be the one belonging to the master connection i.e. it is not
+             possible to forward multiple displays or agents.
+
+             Two additional options allow for opportunistic multiplexing: try
+             to use a master connection but fall back to creating a new one if
+             one does not already exist.  These options are: auto and autoask.
+             The latter requires confirmation like the ask option.
+
+     ControlPath
+             Specify the path to the control socket used for connection
+             sharing as described in the ControlMaster section above or the
+             string none to disable connection sharing.  Arguments to
+             ControlPath may use the tilde syntax to refer to a user's home
+             directory or the tokens described in the TOKENS section.  It is
+             recommended that any ControlPath used for opportunistic
+             connection sharing include at least %h, %p, and %r (or
+             alternatively %C) and be placed in a directory that is not
+             writable by other users.  This ensures that shared connections
+             are uniquely identified.
+
+     ControlPersist
+             When used in conjunction with ControlMaster, specifies that the
+             master connection should remain open in the background (waiting
+             for future client connections) after the initial client
+             connection has been closed.  If set to no, then the master
+             connection will not be placed into the background, and will close
+             as soon as the initial client connection is closed.  If set to
+             yes or 0, then the master connection will remain in the
+             background indefinitely (until killed or closed via a mechanism
+             such as the "ssh -O exit").  If set to a time in seconds, or a
+             time in any of the formats documented in sshd_config(5), then the
+             backgrounded master connection will automatically terminate after
+             it has remained idle (with no client connections) for the
+             specified time.
+
+     DynamicForward
+             Specifies that a TCP port on the local machine be forwarded over
+             the secure channel, and the application protocol is then used to
+             determine where to connect to from the remote machine.
+
+             The argument must be [bind_address:]port.  IPv6 addresses can be
+             specified by enclosing addresses in square brackets.  By default,
+             the local port is bound in accordance with the GatewayPorts
+             setting.  However, an explicit bind_address may be used to bind
+             the connection to a specific address.  The bind_address of
+             localhost indicates that the listening port be bound for local
+             use only, while an empty address or M-bM-^@M-^X*M-bM-^@M-^Y indicates that the port
+             should be available from all interfaces.
+
+             Currently the SOCKS4 and SOCKS5 protocols are supported, and
+             ssh(1) will act as a SOCKS server.  Multiple forwardings may be
+             specified, and additional forwardings can be given on the command
+             line.  Only the superuser can forward privileged ports.
+
+     EnableSSHKeysign
+             Setting this option to yes in the global client configuration
+             file /etc/ssh/ssh_config enables the use of the helper program
+             ssh-keysign(8) during HostbasedAuthentication.  The argument must
+             be yes or no (the default).  This option should be placed in the
+             non-hostspecific section.  See ssh-keysign(8) for more
+             information.
+
+     EscapeChar
+             Sets the escape character (default: M-bM-^@M-^X~M-bM-^@M-^Y).  The escape character
+             can also be set on the command line.  The argument should be a
+             single character, M-bM-^@M-^X^M-bM-^@M-^Y followed by a letter, or none to disable
+             the escape character entirely (making the connection transparent
+             for binary data).
+
+     ExitOnForwardFailure
+             Specifies whether ssh(1) should terminate the connection if it
+             cannot set up all requested dynamic, tunnel, local, and remote
+             port forwardings, (e.g. if either end is unable to bind and
+             listen on a specified port).  Note that ExitOnForwardFailure does
+             not apply to connections made over port forwardings and will not,
+             for example, cause ssh(1) to exit if TCP connections to the
+             ultimate forwarding destination fail.  The argument must be yes
+             or no (the default).
+
+     FingerprintHash
+             Specifies the hash algorithm used when displaying key
+             fingerprints.  Valid options are: md5 and sha256 (the default).
+
+     ForwardAgent
+             Specifies whether the connection to the authentication agent (if
+             any) will be forwarded to the remote machine.  The argument must
+             be yes or no (the default).
+
+             Agent forwarding should be enabled with caution.  Users with the
+             ability to bypass file permissions on the remote host (for the
+             agent's Unix-domain socket) can access the local agent through
+             the forwarded connection.  An attacker cannot obtain key material
+             from the agent, however they can perform operations on the keys
+             that enable them to authenticate using the identities loaded into
+             the agent.
+
+     ForwardX11
+             Specifies whether X11 connections will be automatically
+             redirected over the secure channel and DISPLAY set.  The argument
+             must be yes or no (the default).
+
+             X11 forwarding should be enabled with caution.  Users with the
+             ability to bypass file permissions on the remote host (for the
+             user's X11 authorization database) can access the local X11
+             display through the forwarded connection.  An attacker may then
+             be able to perform activities such as keystroke monitoring if the
+             ForwardX11Trusted option is also enabled.
+
+     ForwardX11Timeout
+             Specify a timeout for untrusted X11 forwarding using the format
+             described in the TIME FORMATS section of sshd_config(5).  X11
+             connections received by ssh(1) after this time will be refused.
+             Setting ForwardX11Timeout to zero will disable the timeout and
+             permit X11 forwarding for the life of the connection.  The
+             default is to disable untrusted X11 forwarding after twenty
+             minutes has elapsed.
+
+     ForwardX11Trusted
+             If this option is set to yes, remote X11 clients will have full
+             access to the original X11 display.
+
+             If this option is set to no (the default), remote X11 clients
+             will be considered untrusted and prevented from stealing or
+             tampering with data belonging to trusted X11 clients.
+             Furthermore, the xauth(1) token used for the session will be set
+             to expire after 20 minutes.  Remote clients will be refused
+             access after this time.
+
+             See the X11 SECURITY extension specification for full details on
+             the restrictions imposed on untrusted clients.
+
+     GatewayPorts
+             Specifies whether remote hosts are allowed to connect to local
+             forwarded ports.  By default, ssh(1) binds local port forwardings
+             to the loopback address.  This prevents other remote hosts from
+             connecting to forwarded ports.  GatewayPorts can be used to
+             specify that ssh should bind local port forwardings to the
+             wildcard address, thus allowing remote hosts to connect to
+             forwarded ports.  The argument must be yes or no (the default).
+
+     GlobalKnownHostsFile
+             Specifies one or more files to use for the global host key
+             database, separated by whitespace.  The default is
+             /etc/ssh/ssh_known_hosts, /etc/ssh/ssh_known_hosts2.
+
+     GSSAPIAuthentication
+             Specifies whether user authentication based on GSSAPI is allowed.
+             The default is no.
+
+     GSSAPIDelegateCredentials
+             Forward (delegate) credentials to the server.  The default is no.
+
+     HashKnownHosts
+             Indicates that ssh(1) should hash host names and addresses when
+             they are added to ~/.ssh/known_hosts.  These hashed names may be
+             used normally by ssh(1) and sshd(8), but they do not reveal
+             identifying information should the file's contents be disclosed.
+             The default is no.  Note that existing names and addresses in
+             known hosts files will not be converted automatically, but may be
+             manually hashed using ssh-keygen(1).
+
+     HostbasedAuthentication
+             Specifies whether to try rhosts based authentication with public
+             key authentication.  The argument must be yes or no (the
+             default).
+
+     HostbasedKeyTypes
+             Specifies the key types that will be used for hostbased
+             authentication as a comma-separated list of patterns.
+             Alternately if the specified value begins with a M-bM-^@M-^X+M-bM-^@M-^Y character,
+             then the specified key types will be appended to the default set
+             instead of replacing them.  If the specified value begins with a
+             M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified key types (including wildcards)
+             will be removed from the default set instead of replacing them.
+             The default for this option is:
+
+                ecdsa-sha2-nistp256-cert-v01@openssh.com,
+                ecdsa-sha2-nistp384-cert-v01@openssh.com,
+                ecdsa-sha2-nistp521-cert-v01@openssh.com,
+                ssh-ed25519-cert-v01@openssh.com,
+                rsa-sha2-512-cert-v01@openssh.com,rsa-sha2-256-cert-v01@openssh.com,
+                ssh-rsa-cert-v01@openssh.com,
+                ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
+                ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa
+
+             The -Q option of ssh(1) may be used to list supported key types.
+
+     HostKeyAlgorithms
+             Specifies the host key algorithms that the client wants to use in
+             order of preference.  Alternately if the specified value begins
+             with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified key types will be
+             appended to the default set instead of replacing them.  If the
+             specified value begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified
+             key types (including wildcards) will be removed from the default
+             set instead of replacing them.  The default for this option is:
+
+                ecdsa-sha2-nistp256-cert-v01@openssh.com,
+                ecdsa-sha2-nistp384-cert-v01@openssh.com,
+                ecdsa-sha2-nistp521-cert-v01@openssh.com,
+                ssh-ed25519-cert-v01@openssh.com,
+                rsa-sha2-512-cert-v01@openssh.com,rsa-sha2-256-cert-v01@openssh.com,
+                ssh-rsa-cert-v01@openssh.com,
+                ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
+                ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa
+
+             If hostkeys are known for the destination host then this default
+             is modified to prefer their algorithms.
+
+             The list of available key types may also be obtained using "ssh
+             -Q key".
+
+     HostKeyAlias
+             Specifies an alias that should be used instead of the real host
+             name when looking up or saving the host key in the host key
+             database files and when validating host certificates.  This
+             option is useful for tunneling SSH connections or for multiple
+             servers running on a single host.
+
+     HostName
+             Specifies the real host name to log into.  This can be used to
+             specify nicknames or abbreviations for hosts.  Arguments to
+             HostName accept the tokens described in the TOKENS section.
+             Numeric IP addresses are also permitted (both on the command line
+             and in HostName specifications).  The default is the name given
+             on the command line.
+
+     IdentitiesOnly
+             Specifies that ssh(1) should only use the authentication identity
+             and certificate files explicitly configured in the ssh_config
+             files or passed on the ssh(1) command-line, even if ssh-agent(1)
+             or a PKCS11Provider offers more identities.  The argument to this
+             keyword must be yes or no (the default).  This option is intended
+             for situations where ssh-agent offers many different identities.
+
+     IdentityAgent
+             Specifies the UNIX-domain socket used to communicate with the
+             authentication agent.
+
+             This option overrides the SSH_AUTH_SOCK environment variable and
+             can be used to select a specific agent.  Setting the socket name
+             to none disables the use of an authentication agent.  If the
+             string "SSH_AUTH_SOCK" is specified, the location of the socket
+             will be read from the SSH_AUTH_SOCK environment variable.
+             Otherwise if the specified value begins with a M-bM-^@M-^X$M-bM-^@M-^Y character,
+             then it will be treated as an environment variable containing the
+             location of the socket.
+
+             Arguments to IdentityAgent may use the tilde syntax to refer to a
+             user's home directory or the tokens described in the TOKENS
+             section.
+
+     IdentityFile
+             Specifies a file from which the user's DSA, ECDSA, Ed25519 or RSA
+             authentication identity is read.  The default is ~/.ssh/id_dsa,
+             ~/.ssh/id_ecdsa, ~/.ssh/id_ed25519 and ~/.ssh/id_rsa.
+             Additionally, any identities represented by the authentication
+             agent will be used for authentication unless IdentitiesOnly is
+             set.  If no certificates have been explicitly specified by
+             CertificateFile, ssh(1) will try to load certificate information
+             from the filename obtained by appending -cert.pub to the path of
+             a specified IdentityFile.
+
+             Arguments to IdentityFile may use the tilde syntax to refer to a
+             user's home directory or the tokens described in the TOKENS
+             section.
+
+             It is possible to have multiple identity files specified in
+             configuration files; all these identities will be tried in
+             sequence.  Multiple IdentityFile directives will add to the list
+             of identities tried (this behaviour differs from that of other
+             configuration directives).
+
+             IdentityFile may be used in conjunction with IdentitiesOnly to
+             select which identities in an agent are offered during
+             authentication.  IdentityFile may also be used in conjunction
+             with CertificateFile in order to provide any certificate also
+             needed for authentication with the identity.
+
+     IgnoreUnknown
+             Specifies a pattern-list of unknown options to be ignored if they
+             are encountered in configuration parsing.  This may be used to
+             suppress errors if ssh_config contains options that are
+             unrecognised by ssh(1).  It is recommended that IgnoreUnknown be
+             listed early in the configuration file as it will not be applied
+             to unknown options that appear before it.
+
+     Include
+             Include the specified configuration file(s).  Multiple pathnames
+             may be specified and each pathname may contain glob(7) wildcards
+             and, for user configurations, shell-like M-bM-^@M-^X~M-bM-^@M-^Y references to user
+             home directories.  Files without absolute paths are assumed to be
+             in ~/.ssh if included in a user configuration file or /etc/ssh if
+             included from the system configuration file.  Include directive
+             may appear inside a Match or Host block to perform conditional
+             inclusion.
+
+     IPQoS   Specifies the IPv4 type-of-service or DSCP class for connections.
+             Accepted values are af11, af12, af13, af21, af22, af23, af31,
+             af32, af33, af41, af42, af43, cs0, cs1, cs2, cs3, cs4, cs5, cs6,
+             cs7, ef, lowdelay, throughput, reliability, a numeric value, or
+             none to use the operating system default.  This option may take
+             one or two arguments, separated by whitespace.  If one argument
+             is specified, it is used as the packet class unconditionally.  If
+             two values are specified, the first is automatically selected for
+             interactive sessions and the second for non-interactive sessions.
+             The default is af21 (Low-Latency Data) for interactive sessions
+             and cs1 (Lower Effort) for non-interactive sessions.
+
+     KbdInteractiveAuthentication
+             Specifies whether to use keyboard-interactive authentication.
+             The argument to this keyword must be yes (the default) or no.
+
+     KbdInteractiveDevices
+             Specifies the list of methods to use in keyboard-interactive
+             authentication.  Multiple method names must be comma-separated.
+             The default is to use the server specified list.  The methods
+             available vary depending on what the server supports.  For an
+             OpenSSH server, it may be zero or more of: bsdauth and pam.
+
+     KexAlgorithms
+             Specifies the available KEX (Key Exchange) algorithms.  Multiple
+             algorithms must be comma-separated.  Alternately if the specified
+             value begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified methods
+             will be appended to the default set instead of replacing them.
+             If the specified value begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the
+             specified methods (including wildcards) will be removed from the
+             default set instead of replacing them.  The default is:
+
+                   curve25519-sha256,curve25519-sha256@libssh.org,
+                   ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,
+                   diffie-hellman-group-exchange-sha256,
+                   diffie-hellman-group16-sha512,
+                   diffie-hellman-group18-sha512,
+                   diffie-hellman-group-exchange-sha1,
+                   diffie-hellman-group14-sha256,
+                   diffie-hellman-group14-sha1
+
+             The list of available key exchange algorithms may also be
+             obtained using "ssh -Q kex".
+
+     LocalCommand
+             Specifies a command to execute on the local machine after
+             successfully connecting to the server.  The command string
+             extends to the end of the line, and is executed with the user's
+             shell.  Arguments to LocalCommand accept the tokens described in
+             the TOKENS section.
+
+             The command is run synchronously and does not have access to the
+             session of the ssh(1) that spawned it.  It should not be used for
+             interactive commands.
+
+             This directive is ignored unless PermitLocalCommand has been
+             enabled.
+
+     LocalForward
+             Specifies that a TCP port on the local machine be forwarded over
+             the secure channel to the specified host and port from the remote
+             machine.  The first argument must be [bind_address:]port and the
+             second argument must be host:hostport.  IPv6 addresses can be
+             specified by enclosing addresses in square brackets.  Multiple
+             forwardings may be specified, and additional forwardings can be
+             given on the command line.  Only the superuser can forward
+             privileged ports.  By default, the local port is bound in
+             accordance with the GatewayPorts setting.  However, an explicit
+             bind_address may be used to bind the connection to a specific
+             address.  The bind_address of localhost indicates that the
+             listening port be bound for local use only, while an empty
+             address or M-bM-^@M-^X*M-bM-^@M-^Y indicates that the port should be available from
+             all interfaces.
+
+     LogLevel
+             Gives the verbosity level that is used when logging messages from
+             ssh(1).  The possible values are: QUIET, FATAL, ERROR, INFO,
+             VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3.  The default is INFO.
+             DEBUG and DEBUG1 are equivalent.  DEBUG2 and DEBUG3 each specify
+             higher levels of verbose output.
+
+     MACs    Specifies the MAC (message authentication code) algorithms in
+             order of preference.  The MAC algorithm is used for data
+             integrity protection.  Multiple algorithms must be comma-
+             separated.  If the specified value begins with a M-bM-^@M-^X+M-bM-^@M-^Y character,
+             then the specified algorithms will be appended to the default set
+             instead of replacing them.  If the specified value begins with a
+             M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified algorithms (including
+             wildcards) will be removed from the default set instead of
+             replacing them.
+
+             The algorithms that contain "-etm" calculate the MAC after
+             encryption (encrypt-then-mac).  These are considered safer and
+             their use recommended.
+
+             The default is:
+
+                   umac-64-etm@openssh.com,umac-128-etm@openssh.com,
+                   hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com,
+                   hmac-sha1-etm@openssh.com,
+                   umac-64@openssh.com,umac-128@openssh.com,
+                   hmac-sha2-256,hmac-sha2-512,hmac-sha1
+
+             The list of available MAC algorithms may also be obtained using
+             "ssh -Q mac".
+
+     NoHostAuthenticationForLocalhost
+             Disable host authentication for localhost (loopback addresses).
+             The argument to this keyword must be yes or no (the default).
+
+     NumberOfPasswordPrompts
+             Specifies the number of password prompts before giving up.  The
+             argument to this keyword must be an integer.  The default is 3.
+
+     PasswordAuthentication
+             Specifies whether to use password authentication.  The argument
+             to this keyword must be yes (the default) or no.
+
+     PermitLocalCommand
+             Allow local command execution via the LocalCommand option or
+             using the !command escape sequence in ssh(1).  The argument must
+             be yes or no (the default).
+
+     PKCS11Provider
+             Specifies which PKCS#11 provider to use.  The argument to this
+             keyword is the PKCS#11 shared library ssh(1) should use to
+             communicate with a PKCS#11 token providing the user's private RSA
+             key.
+
+     Port    Specifies the port number to connect on the remote host.  The
+             default is 22.
+
+     PreferredAuthentications
+             Specifies the order in which the client should try authentication
+             methods.  This allows a client to prefer one method (e.g.
+             keyboard-interactive) over another method (e.g. password).  The
+             default is:
+
+                   gssapi-with-mic,hostbased,publickey,
+                   keyboard-interactive,password
+
+     ProxyCommand
+             Specifies the command to use to connect to the server.  The
+             command string extends to the end of the line, and is executed
+             using the user's shell M-bM-^@M-^XexecM-bM-^@M-^Y directive to avoid a lingering
+             shell process.
+
+             Arguments to ProxyCommand accept the tokens described in the
+             TOKENS section.  The command can be basically anything, and
+             should read from its standard input and write to its standard
+             output.  It should eventually connect an sshd(8) server running
+             on some machine, or execute sshd -i somewhere.  Host key
+             management will be done using the HostName of the host being
+             connected (defaulting to the name typed by the user).  Setting
+             the command to none disables this option entirely.  Note that
+             CheckHostIP is not available for connects with a proxy command.
+
+             This directive is useful in conjunction with nc(1) and its proxy
+             support.  For example, the following directive would connect via
+             an HTTP proxy at 192.0.2.0:
+
+                ProxyCommand /usr/bin/nc -X connect -x 192.0.2.0:8080 %h %p
+
+     ProxyJump
+             Specifies one or more jump proxies as either [user@]host[:port]
+             or an ssh URI.  Multiple proxies may be separated by comma
+             characters and will be visited sequentially.  Setting this option
+             will cause ssh(1) to connect to the target host by first making a
+             ssh(1) connection to the specified ProxyJump host and then
+             establishing a TCP forwarding to the ultimate target from there.
+
+             Note that this option will compete with the ProxyCommand option -
+             whichever is specified first will prevent later instances of the
+             other from taking effect.
+
+     ProxyUseFdpass
+             Specifies that ProxyCommand will pass a connected file descriptor
+             back to ssh(1) instead of continuing to execute and pass data.
+             The default is no.
+
+     PubkeyAcceptedKeyTypes
+             Specifies the key types that will be used for public key
+             authentication as a comma-separated list of patterns.
+             Alternately if the specified value begins with a M-bM-^@M-^X+M-bM-^@M-^Y character,
+             then the key types after it will be appended to the default
+             instead of replacing it.  If the specified value begins with a
+             M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified key types (including wildcards)
+             will be removed from the default set instead of replacing them.
+             The default for this option is:
+
+                ecdsa-sha2-nistp256-cert-v01@openssh.com,
+                ecdsa-sha2-nistp384-cert-v01@openssh.com,
+                ecdsa-sha2-nistp521-cert-v01@openssh.com,
+                ssh-ed25519-cert-v01@openssh.com,
+                rsa-sha2-512-cert-v01@openssh.com,rsa-sha2-256-cert-v01@openssh.com,

+                ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa
+
+             The list of available key types may also be obtained using "ssh
+             -Q key".
+
+     PubkeyAuthentication
+             Specifies whether to try public key authentication.  The argument
+             to this keyword must be yes (the default) or no.
+
+     RekeyLimit
+             Specifies the maximum amount of data that may be transmitted
+             before the session key is renegotiated, optionally followed a
+             maximum amount of time that may pass before the session key is
+             renegotiated.  The first argument is specified in bytes and may
+             have a suffix of M-bM-^@M-^XKM-bM-^@M-^Y, M-bM-^@M-^XMM-bM-^@M-^Y, or M-bM-^@M-^XGM-bM-^@M-^Y to indicate Kilobytes,
+             Megabytes, or Gigabytes, respectively.  The default is between
+             M-bM-^@M-^X1GM-bM-^@M-^Y and M-bM-^@M-^X4GM-bM-^@M-^Y, depending on the cipher.  The optional second
+             value is specified in seconds and may use any of the units
+             documented in the TIME FORMATS section of sshd_config(5).  The
+             default value for RekeyLimit is default none, which means that
+             rekeying is performed after the cipher's default amount of data
+             has been sent or received and no time based rekeying is done.
+
+     RemoteCommand
+             Specifies a command to execute on the remote machine after
+             successfully connecting to the server.  The command string
+             extends to the end of the line, and is executed with the user's
+             shell.  Arguments to RemoteCommand accept the tokens described in
+             the TOKENS section.
+
+     RemoteForward
+             Specifies that a TCP port on the remote machine be forwarded over
+             the secure channel.  The remote port may either be forwarded to a
+             specified host and port from the local machine, or may act as a
+             SOCKS 4/5 proxy that allows a remote client to connect to
+             arbitrary destinations from the local machine.  The first
+             argument must be [bind_address:]port If forwarding to a specific
+             destination then the second argument must be host:hostport,
+             otherwise if no destination argument is specified then the remote
+             forwarding will be established as a SOCKS proxy.
+
+             IPv6 addresses can be specified by enclosing addresses in square
+             brackets.  Multiple forwardings may be specified, and additional
+             forwardings can be given on the command line.  Privileged ports
+             can be forwarded only when logging in as root on the remote
+             machine.
+
+             If the port argument is 0, the listen port will be dynamically
+             allocated on the server and reported to the client at run time.
+
+             If the bind_address is not specified, the default is to only bind
+             to loopback addresses.  If the bind_address is M-bM-^@M-^X*M-bM-^@M-^Y or an empty
+             string, then the forwarding is requested to listen on all
+             interfaces.  Specifying a remote bind_address will only succeed
+             if the server's GatewayPorts option is enabled (see
+             sshd_config(5)).
+
+     RequestTTY
+             Specifies whether to request a pseudo-tty for the session.  The
+             argument may be one of: no (never request a TTY), yes (always
+             request a TTY when standard input is a TTY), force (always
+             request a TTY) or auto (request a TTY when opening a login
+             session).  This option mirrors the -t and -T flags for ssh(1).
+
+     RevokedHostKeys
+             Specifies revoked host public keys.  Keys listed in this file
+             will be refused for host authentication.  Note that if this file
+             does not exist or is not readable, then host authentication will
+             be refused for all hosts.  Keys may be specified as a text file,
+             listing one public key per line, or as an OpenSSH Key Revocation
+             List (KRL) as generated by ssh-keygen(1).  For more information
+             on KRLs, see the KEY REVOCATION LISTS section in ssh-keygen(1).
+
+     SendEnv
+             Specifies what variables from the local environ(7) should be sent
+             to the server.  The server must also support it, and the server
+             must be configured to accept these environment variables.  Note
+             that the TERM environment variable is always sent whenever a
+             pseudo-terminal is requested as it is required by the protocol.
+             Refer to AcceptEnv in sshd_config(5) for how to configure the
+             server.  Variables are specified by name, which may contain
+             wildcard characters.  Multiple environment variables may be
+             separated by whitespace or spread across multiple SendEnv
+             directives.
+
+             See PATTERNS for more information on patterns.
+
+             It is possible to clear previously set SendEnv variable names by
+             prefixing patterns with -.  The default is not to send any
+             environment variables.
+
+     ServerAliveCountMax
+             Sets the number of server alive messages (see below) which may be
+             sent without ssh(1) receiving any messages back from the server.
+             If this threshold is reached while server alive messages are
+             being sent, ssh will disconnect from the server, terminating the
+             session.  It is important to note that the use of server alive
+             messages is very different from TCPKeepAlive (below).  The server
+             alive messages are sent through the encrypted channel and
+             therefore will not be spoofable.  The TCP keepalive option
+             enabled by TCPKeepAlive is spoofable.  The server alive mechanism
+             is valuable when the client or server depend on knowing when a
+             connection has become inactive.
+
+             The default value is 3.  If, for example, ServerAliveInterval
+             (see below) is set to 15 and ServerAliveCountMax is left at the
+             default, if the server becomes unresponsive, ssh will disconnect
+             after approximately 45 seconds.
+
+     ServerAliveInterval
+             Sets a timeout interval in seconds after which if no data has
+             been received from the server, ssh(1) will send a message through
+             the encrypted channel to request a response from the server.  The
+             default is 0, indicating that these messages will not be sent to
+             the server.
+
+     SetEnv  Directly specify one or more environment variables and their
+             contents to be sent to the server.  Similarly to SendEnv, the
+             server must be prepared to accept the environment variable.
+
+     StreamLocalBindMask
+             Sets the octal file creation mode mask (umask) used when creating
+             a Unix-domain socket file for local or remote port forwarding.
+             This option is only used for port forwarding to a Unix-domain
+             socket file.
+
+             The default value is 0177, which creates a Unix-domain socket
+             file that is readable and writable only by the owner.  Note that
+             not all operating systems honor the file mode on Unix-domain
+             socket files.
+
+     StreamLocalBindUnlink
+             Specifies whether to remove an existing Unix-domain socket file
+             for local or remote port forwarding before creating a new one.
+             If the socket file already exists and StreamLocalBindUnlink is
+             not enabled, ssh will be unable to forward the port to the Unix-
+             domain socket file.  This option is only used for port forwarding
+             to a Unix-domain socket file.
+
+             The argument must be yes or no (the default).
+
+     StrictHostKeyChecking
+             If this flag is set to yes, ssh(1) will never automatically add
+             host keys to the ~/.ssh/known_hosts file, and refuses to connect
+             to hosts whose host key has changed.  This provides maximum
+             protection against man-in-the-middle (MITM) attacks, though it
+             can be annoying when the /etc/ssh/ssh_known_hosts file is poorly
+             maintained or when connections to new hosts are frequently made.
+             This option forces the user to manually add all new hosts.
+
+             If this flag is set to M-bM-^@M-^\accept-newM-bM-^@M-^] then ssh will automatically
+             add new host keys to the user known hosts files, but will not
+             permit connections to hosts with changed host keys.  If this flag
+             is set to M-bM-^@M-^\noM-bM-^@M-^] or M-bM-^@M-^\offM-bM-^@M-^], ssh will automatically add new host keys
+             to the user known hosts files and allow connections to hosts with
+             changed hostkeys to proceed, subject to some restrictions.  If
+             this flag is set to ask (the default), new host keys will be
+             added to the user known host files only after the user has
+             confirmed that is what they really want to do, and ssh will
+             refuse to connect to hosts whose host key has changed.  The host
+             keys of known hosts will be verified automatically in all cases.
+
+     SyslogFacility
+             Gives the facility code that is used when logging messages from
+             ssh(1).  The possible values are: DAEMON, USER, AUTH, LOCAL0,
+             LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.  The
+             default is USER.
+
+     TCPKeepAlive
+             Specifies whether the system should send TCP keepalive messages
+             to the other side.  If they are sent, death of the connection or
+             crash of one of the machines will be properly noticed.  However,
+             this means that connections will die if the route is down
+             temporarily, and some people find it annoying.
+
+             The default is yes (to send TCP keepalive messages), and the
+             client will notice if the network goes down or the remote host
+             dies.  This is important in scripts, and many users want it too.
+
+             To disable TCP keepalive messages, the value should be set to no.
+             See also ServerAliveInterval for protocol-level keepalives.
+
+     Tunnel  Request tun(4) device forwarding between the client and the
+             server.  The argument must be yes, point-to-point (layer 3),
+             ethernet (layer 2), or no (the default).  Specifying yes requests
+             the default tunnel mode, which is point-to-point.
+
+     TunnelDevice
+             Specifies the tun(4) devices to open on the client (local_tun)
+             and the server (remote_tun).
+
+             The argument must be local_tun[:remote_tun].  The devices may be
+             specified by numerical ID or the keyword any, which uses the next
+             available tunnel device.  If remote_tun is not specified, it
+             defaults to any.  The default is any:any.
+
+     UpdateHostKeys
+             Specifies whether ssh(1) should accept notifications of
+             additional hostkeys from the server sent after authentication has
+             completed and add them to UserKnownHostsFile.  The argument must
+             be yes, no (the default) or ask.  Enabling this option allows
+             learning alternate hostkeys for a server and supports graceful
+             key rotation by allowing a server to send replacement public keys
+             before old ones are removed.  Additional hostkeys are only
+             accepted if the key used to authenticate the host was already
+             trusted or explicitly accepted by the user.  If UpdateHostKeys is
+             set to ask, then the user is asked to confirm the modifications
+             to the known_hosts file.  Confirmation is currently incompatible
+             with ControlPersist, and will be disabled if it is enabled.
+
+             Presently, only sshd(8) from OpenSSH 6.8 and greater support the
+             "hostkeys@openssh.com" protocol extension used to inform the
+             client of all the server's hostkeys.
+
+     User    Specifies the user to log in as.  This can be useful when a
+             different user name is used on different machines.  This saves
+             the trouble of having to remember to give the user name on the
+             command line.
+
+     UserKnownHostsFile
+             Specifies one or more files to use for the user host key
+             database, separated by whitespace.  The default is
+             ~/.ssh/known_hosts, ~/.ssh/known_hosts2.
+
+     VerifyHostKeyDNS
+             Specifies whether to verify the remote key using DNS and SSHFP
+             resource records.  If this option is set to yes, the client will
+             implicitly trust keys that match a secure fingerprint from DNS.
+             Insecure fingerprints will be handled as if this option was set
+             to ask.  If this option is set to ask, information on fingerprint
+             match will be displayed, but the user will still need to confirm
+             new host keys according to the StrictHostKeyChecking option.  The
+             default is no.
+
+             See also VERIFYING HOST KEYS in ssh(1).
+
+     VisualHostKey
+             If this flag is set to yes, an ASCII art representation of the
+             remote host key fingerprint is printed in addition to the
+             fingerprint string at login and for unknown host keys.  If this
+             flag is set to no (the default), no fingerprint strings are
+             printed at login and only the fingerprint string will be printed
+             for unknown host keys.
+
+     XAuthLocation
+             Specifies the full pathname of the xauth(1) program.  The default
+             is /usr/X11R6/bin/xauth.
+
+PATTERNS
+     A pattern consists of zero or more non-whitespace characters, M-bM-^@M-^X*M-bM-^@M-^Y (a
+     wildcard that matches zero or more characters), or M-bM-^@M-^X?M-bM-^@M-^Y (a wildcard that
+     matches exactly one character).  For example, to specify a set of
+     declarations for any host in the ".co.uk" set of domains, the following
+     pattern could be used:
+
+           Host *.co.uk
+
+     The following pattern would match any host in the 192.168.0.[0-9] network
+     range:
+
+           Host 192.168.0.?
+
+     A pattern-list is a comma-separated list of patterns.  Patterns within
+     pattern-lists may be negated by preceding them with an exclamation mark
+     (M-bM-^@M-^X!M-bM-^@M-^Y).  For example, to allow a key to be used from anywhere within an
+     organization except from the "dialup" pool, the following entry (in
+     authorized_keys) could be used:
+
+           from="!*.dialup.example.com,*.example.com"
+
+     Note that a negated match will never produce a positive result by itself.
+     For example, attempting to match "host3" against the following pattern-
+     list will fail:
+
+           from="!host1,!host2"
+
+     The solution here is to include a term that will yield a positive match,
+     such as a wildcard:
+
+           from="!host1,!host2,*"
+
+TOKENS
+     Arguments to some keywords can make use of tokens, which are expanded at
+     runtime:
+
+           %%    A literal M-bM-^@M-^X%M-bM-^@M-^Y.
+           %C    Hash of %l%h%p%r.
+           %d    Local user's home directory.
+           %h    The remote hostname.
+           %i    The local user ID.
+           %L    The local hostname.
+           %l    The local hostname, including the domain name.
+           %n    The original remote hostname, as given on the command line.
+           %p    The remote port.
+           %r    The remote username.
+           %T    The local tun(4) or tap(4) network interface assigned if
+                 tunnel forwarding was requested, or "NONE" otherwise.
+           %u    The local username.
+
+     Match exec accepts the tokens %%, %h, %i, %L, %l, %n, %p, %r, and %u.
+
+     CertificateFile accepts the tokens %%, %d, %h, %i, %l, %r, and %u.
+
+     ControlPath accepts the tokens %%, %C, %h, %i, %L, %l, %n, %p, %r, and
+     %u.
+
+     HostName accepts the tokens %% and %h.
+
+     IdentityAgent and IdentityFile accept the tokens %%, %d, %h, %i, %l, %r,
+     and %u.
+
+     LocalCommand accepts the tokens %%, %C, %d, %h, %i, %l, %n, %p, %r, %T,
+     and %u.
+
+     ProxyCommand accepts the tokens %%, %h, %p, and %r.

+NAME
+     sshd M-bM-^@M-^S OpenSSH SSH daemon
+
+SYNOPSIS
+     sshd [-46DdeiqTt] [-C connection_spec] [-c host_certificate_file]
+          [-E log_file] [-f config_file] [-g login_grace_time]
+          [-h host_key_file] [-o option] [-p port] [-u len]
+
+DESCRIPTION
+     sshd (OpenSSH Daemon) is the daemon program for ssh(1).  Together these
+     programs replace rlogin and rsh, and provide secure encrypted
+     communications between two untrusted hosts over an insecure network.
+
+     sshd listens for connections from clients.  It is normally started at
+     boot from /etc/rc.  It forks a new daemon for each incoming connection.
+     The forked daemons handle key exchange, encryption, authentication,
+     command execution, and data exchange.
+
+     sshd can be configured using command-line options or a configuration file
+     (by default sshd_config(5)); command-line options override values
+     specified in the configuration file.  sshd rereads its configuration file
+     when it receives a hangup signal, SIGHUP, by executing itself with the
+     name and options it was started with, e.g. /usr/sbin/sshd.
+
+     The options are as follows:
+
+     -4      Forces sshd to use IPv4 addresses only.
+
+     -6      Forces sshd to use IPv6 addresses only.
+
+     -C connection_spec
+             Specify the connection parameters to use for the -T extended test
+             mode.  If provided, any Match directives in the configuration
+             file that would apply are applied before the configuration is
+             written to standard output.  The connection parameters are
+             supplied as keyword=value pairs and may be supplied in any order,
+             either with multiple -C options or as a comma-separated list.
+             The keywords are M-bM-^@M-^\addr,M-bM-^@M-^] M-bM-^@M-^\userM-bM-^@M-^], M-bM-^@M-^\hostM-bM-^@M-^], M-bM-^@M-^\laddrM-bM-^@M-^], M-bM-^@M-^\lportM-bM-^@M-^], and
+             M-bM-^@M-^\rdomainM-bM-^@M-^] and correspond to source address, user, resolved source
+             host name, local address, local port number and routing domain
+             respectively.
+
+     -c host_certificate_file
+             Specifies a path to a certificate file to identify sshd during
+             key exchange.  The certificate file must match a host key file
+             specified using the -h option or the HostKey configuration
+             directive.
+
+     -D      When this option is specified, sshd will not detach and does not
+             become a daemon.  This allows easy monitoring of sshd.
+
+     -d      Debug mode.  The server sends verbose debug output to standard
+             error, and does not put itself in the background.  The server
+             also will not fork and will only process one connection.  This
+             option is only intended for debugging for the server.  Multiple
+             -d options increase the debugging level.  Maximum is 3.
+
+     -E log_file
+             Append debug logs to log_file instead of the system log.
+
+     -e      Write debug logs to standard error instead of the system log.
+
+     -f config_file
+             Specifies the name of the configuration file.  The default is
+             /etc/ssh/sshd_config.  sshd refuses to start if there is no
+             configuration file.
+
+     -g login_grace_time
+             Gives the grace time for clients to authenticate themselves
+             (default 120 seconds).  If the client fails to authenticate the
+             user within this many seconds, the server disconnects and exits.
+             A value of zero indicates no limit.
+
+     -h host_key_file
+             Specifies a file from which a host key is read.  This option must
+             be given if sshd is not run as root (as the normal host key files
+             are normally not readable by anyone but root).  The default is
+             /etc/ssh/ssh_host_ecdsa_key, /etc/ssh/ssh_host_ed25519_key and
+             /etc/ssh/ssh_host_rsa_key.  It is possible to have multiple host
+             key files for the different host key algorithms.
+
+     -i      Specifies that sshd is being run from inetd(8).
+
+     -o option
+             Can be used to give options in the format used in the
+             configuration file.  This is useful for specifying options for
+             which there is no separate command-line flag.  For full details
+             of the options, and their values, see sshd_config(5).
+
+     -p port
+             Specifies the port on which the server listens for connections
+             (default 22).  Multiple port options are permitted.  Ports
+             specified in the configuration file with the Port option are
+             ignored when a command-line port is specified.  Ports specified
+             using the ListenAddress option override command-line ports.
+
+     -q      Quiet mode.  Nothing is sent to the system log.  Normally the
+             beginning, authentication, and termination of each connection is
+             logged.
+
+     -T      Extended test mode.  Check the validity of the configuration
+             file, output the effective configuration to stdout and then exit.
+             Optionally, Match rules may be applied by specifying the
+             connection parameters using one or more -C options.
+
+     -t      Test mode.  Only check the validity of the configuration file and
+             sanity of the keys.  This is useful for updating sshd reliably as
+             configuration options may change.
+
+     -u len  This option is used to specify the size of the field in the utmp
+             structure that holds the remote host name.  If the resolved host
+             name is longer than len, the dotted decimal value will be used
+             instead.  This allows hosts with very long host names that
+             overflow this field to still be uniquely identified.  Specifying
+             -u0 indicates that only dotted decimal addresses should be put
+             into the utmp file.  -u0 may also be used to prevent sshd from
+             making DNS requests unless the authentication mechanism or
+             configuration requires it.  Authentication mechanisms that may
+             require DNS include HostbasedAuthentication and using a
+             from="pattern-list" option in a key file.  Configuration options
+             that require DNS include using a USER@HOST pattern in AllowUsers
+             or DenyUsers.
+
+AUTHENTICATION
+     The OpenSSH SSH daemon supports SSH protocol 2 only.  Each host has a
+     host-specific key, used to identify the host.  Whenever a client
+     connects, the daemon responds with its public host key.  The client
+     compares the host key against its own database to verify that it has not
+     changed.  Forward security is provided through a Diffie-Hellman key
+     agreement.  This key agreement results in a shared session key.  The rest
+     of the session is encrypted using a symmetric cipher, currently 128-bit
+     AES, Blowfish, 3DES, CAST128, Arcfour, 192-bit AES, or 256-bit AES.  The
+     client selects the encryption algorithm to use from those offered by the
+     server.  Additionally, session integrity is provided through a
+     cryptographic message authentication code (hmac-md5, hmac-sha1, umac-64,
+     umac-128, hmac-sha2-256 or hmac-sha2-512).
+
+     Finally, the server and the client enter an authentication dialog.  The
+     client tries to authenticate itself using host-based authentication,
+     public key authentication, challenge-response authentication, or password
+     authentication.
+
+     Regardless of the authentication type, the account is checked to ensure
+     that it is accessible.  An account is not accessible if it is locked,
+     listed in DenyUsers or its group is listed in DenyGroups .  The
+     definition of a locked account is system dependent. Some platforms have
+     their own account database (eg AIX) and some modify the passwd field (
+     M-bM-^@M-^X*LK*M-bM-^@M-^Y on Solaris and UnixWare, M-bM-^@M-^X*M-bM-^@M-^Y on HP-UX, containing M-bM-^@M-^XNologinM-bM-^@M-^Y on
+     Tru64, a leading M-bM-^@M-^X*LOCKED*M-bM-^@M-^Y on FreeBSD and a leading M-bM-^@M-^X!M-bM-^@M-^Y on most
+     Linuxes).  If there is a requirement to disable password authentication
+     for the account while allowing still public-key, then the passwd field
+     should be set to something other than these values (eg M-bM-^@M-^XNPM-bM-^@M-^Y or M-bM-^@M-^X*NP*M-bM-^@M-^Y ).
+
+     If the client successfully authenticates itself, a dialog for preparing
+     the session is entered.  At this time the client may request things like
+     allocating a pseudo-tty, forwarding X11 connections, forwarding TCP
+     connections, or forwarding the authentication agent connection over the
+     secure channel.
+
+     After this, the client either requests a shell or execution of a command.
+     The sides then enter session mode.  In this mode, either side may send
+     data at any time, and such data is forwarded to/from the shell or command
+     on the server side, and the user terminal in the client side.
+
+     When the user program terminates and all forwarded X11 and other
+     connections have been closed, the server sends command exit status to the
+     client, and both sides exit.
+
+LOGIN PROCESS
+     When a user successfully logs in, sshd does the following:
+
+           1.   If the login is on a tty, and no command has been specified,
+                prints last login time and /etc/motd (unless prevented in the
+                configuration file or by ~/.hushlogin; see the FILES section).
+
+           2.   If the login is on a tty, records login time.
+
+           3.   Checks /etc/nologin; if it exists, prints contents and quits
+                (unless root).
+
+           4.   Changes to run with normal user privileges.
+
+           5.   Sets up basic environment.
+
+           6.   Reads the file ~/.ssh/environment, if it exists, and users are
+                allowed to change their environment.  See the
+                PermitUserEnvironment option in sshd_config(5).
+
+           7.   Changes to user's home directory.
+
+           8.   If ~/.ssh/rc exists and the sshd_config(5) PermitUserRC option
+                is set, runs it; else if /etc/ssh/sshrc exists, runs it;
+                otherwise runs xauth.  The M-bM-^@M-^\rcM-bM-^@M-^] files are given the X11
+                authentication protocol and cookie in standard input.  See
+                SSHRC, below.
+
+           9.   Runs user's shell or command.  All commands are run under the
+                user's login shell as specified in the system password
+                database.
+
+SSHRC
+     If the file ~/.ssh/rc exists, sh(1) runs it after reading the environment
+     files but before starting the user's shell or command.  It must not
+     produce any output on stdout; stderr must be used instead.  If X11
+     forwarding is in use, it will receive the "proto cookie" pair in its
+     standard input (and DISPLAY in its environment).  The script must call
+     xauth(1) because sshd will not run xauth automatically to add X11
+     cookies.
+
+     The primary purpose of this file is to run any initialization routines
+     which may be needed before the user's home directory becomes accessible;
+     AFS is a particular example of such an environment.
+
+     This file will probably contain some initialization code followed by
+     something similar to:
+
+        if read proto cookie && [ -n "$DISPLAY" ]; then
+                if [ `echo $DISPLAY | cut -c1-10` = 'localhost:' ]; then
+                        # X11UseLocalhost=yes
+                        echo add unix:`echo $DISPLAY |
+                            cut -c11-` $proto $cookie
+                else
+                        # X11UseLocalhost=no
+                        echo add $DISPLAY $proto $cookie
+                fi | xauth -q -
+        fi
+
+     If this file does not exist, /etc/ssh/sshrc is run, and if that does not
+     exist either, xauth is used to add the cookie.
+
+AUTHORIZED_KEYS FILE FORMAT
+     AuthorizedKeysFile specifies the files containing public keys for public
+     key authentication; if this option is not specified, the default is
+     ~/.ssh/authorized_keys and ~/.ssh/authorized_keys2.  Each line of the
+     file contains one key (empty lines and lines starting with a M-bM-^@M-^X#M-bM-^@M-^Y are
+     ignored as comments).  Public keys consist of the following space-
+     separated fields: options, keytype, base64-encoded key, comment.  The
+     options field is optional.  The keytype is M-bM-^@M-^\ecdsa-sha2-nistp256M-bM-^@M-^],
+     M-bM-^@M-^\ecdsa-sha2-nistp384M-bM-^@M-^], M-bM-^@M-^\ecdsa-sha2-nistp521M-bM-^@M-^], M-bM-^@M-^\ssh-ed25519M-bM-^@M-^], M-bM-^@M-^\ssh-dssM-bM-^@M-^] or
+     M-bM-^@M-^\ssh-rsaM-bM-^@M-^]; the comment field is not used for anything (but may be
+     convenient for the user to identify the key).
+
+     Note that lines in this file can be several hundred bytes long (because
+     of the size of the public key encoding) up to a limit of 8 kilobytes,
+     which permits DSA keys up to 8 kilobits and RSA keys up to 16 kilobits.
+     You don't want to type them in; instead, copy the id_dsa.pub,
+     id_ecdsa.pub, id_ed25519.pub, or the id_rsa.pub file and edit it.
+
+     sshd enforces a minimum RSA key modulus size of 1024 bits.
+
+     The options (if present) consist of comma-separated option
+     specifications.  No spaces are permitted, except within double quotes.
+     The following option specifications are supported (note that option
+     keywords are case-insensitive):
+
+     agent-forwarding
+             Enable authentication agent forwarding previously disabled by the
+             restrict option.
+
+     cert-authority
+             Specifies that the listed key is a certification authority (CA)
+             that is trusted to validate signed certificates for user
+             authentication.
+
+             Certificates may encode access restrictions similar to these key
+             options.  If both certificate restrictions and key options are
+             present, the most restrictive union of the two is applied.
+
+     command="command"
+             Specifies that the command is executed whenever this key is used
+             for authentication.  The command supplied by the user (if any) is
+             ignored.  The command is run on a pty if the client requests a
+             pty; otherwise it is run without a tty.  If an 8-bit clean
+             channel is required, one must not request a pty or should specify
+             no-pty.  A quote may be included in the command by quoting it
+             with a backslash.
+
+             This option might be useful to restrict certain public keys to
+             perform just a specific operation.  An example might be a key
+             that permits remote backups but nothing else.  Note that the
+             client may specify TCP and/or X11 forwarding unless they are
+             explicitly prohibited, e.g. using the restrict key option.
+
+             The command originally supplied by the client is available in the
+             SSH_ORIGINAL_COMMAND environment variable.  Note that this option
+             applies to shell, command or subsystem execution.  Also note that
+             this command may be superseded by a sshd_config(5) ForceCommand
+             directive.
+
+             If a command is specified and a forced-command is embedded in a
+             certificate used for authentication, then the certificate will be
+             accepted only if the two commands are identical.
+
+     environment="NAME=value"
+             Specifies that the string is to be added to the environment when
+             logging in using this key.  Environment variables set this way
+             override other default environment values.  Multiple options of
+             this type are permitted.  Environment processing is disabled by
+             default and is controlled via the PermitUserEnvironment option.
+
+     expiry-time="timespec"
+             Specifies a time after which the key will not be accepted.  The
+             time may be specified as a YYYYMMDD date or a YYYYMMDDHHMM[SS]
+             time in the system time-zone.
+
+     from="pattern-list"
+             Specifies that in addition to public key authentication, either
+             the canonical name of the remote host or its IP address must be
+             present in the comma-separated list of patterns.  See PATTERNS in
+             ssh_config(5) for more information on patterns.
+
+             In addition to the wildcard matching that may be applied to
+             hostnames or addresses, a from stanza may match IP addresses
+             using CIDR address/masklen notation.
+
+             The purpose of this option is to optionally increase security:
+             public key authentication by itself does not trust the network or
+             name servers or anything (but the key); however, if somebody
+             somehow steals the key, the key permits an intruder to log in
+             from anywhere in the world.  This additional option makes using a
+             stolen key more difficult (name servers and/or routers would have
+             to be compromised in addition to just the key).
+
+     no-agent-forwarding
+             Forbids authentication agent forwarding when this key is used for
+             authentication.
+
+     no-port-forwarding
+             Forbids TCP forwarding when this key is used for authentication.
+             Any port forward requests by the client will return an error.
+             This might be used, e.g. in connection with the command option.
+
+     no-pty  Prevents tty allocation (a request to allocate a pty will fail).
+
+     no-user-rc
+             Disables execution of ~/.ssh/rc.
+
+     no-X11-forwarding
+             Forbids X11 forwarding when this key is used for authentication.
+             Any X11 forward requests by the client will return an error.
+
+     permitlisten="[host:]port"
+             Limit remote port forwarding with the ssh(1) -R option such that
+             it may only listen on the specified host (optional) and port.
+             IPv6 addresses can be specified by enclosing the address in
+             square brackets.  Multiple permitlisten options may be applied
+             separated by commas.  Hostnames may include wildcards as
+             described in the PATTERNS section in ssh_config(5).  A port
+             specification of * matches any port.  Note that the setting of
+             GatewayPorts may further restrict listen addresses.  Note that
+             ssh(1) will send a hostname of M-bM-^@M-^\localhostM-bM-^@M-^] if a listen host was
+             not specified when the forwarding was requested, and that this
+             name is treated differently to the explicit localhost addresses
+             M-bM-^@M-^\127.0.0.1M-bM-^@M-^] and M-bM-^@M-^\::1M-bM-^@M-^].
+
+     permitopen="host:port"
+             Limit local port forwarding with the ssh(1) -L option such that
+             it may only connect to the specified host and port.  IPv6
+             addresses can be specified by enclosing the address in square
+             brackets.  Multiple permitopen options may be applied separated
+             by commas.  No pattern matching is performed on the specified
+             hostnames, they must be literal domains or addresses.  A port
+             specification of * matches any port.
+
+     port-forwarding
+             Enable port forwarding previously disabled by the restrict
+             option.
+
+     principals="principals"
+             On a cert-authority line, specifies allowed principals for
+             certificate authentication as a comma-separated list.  At least
+             one name from the list must appear in the certificate's list of
+             principals for the certificate to be accepted.  This option is
+             ignored for keys that are not marked as trusted certificate
+             signers using the cert-authority option.
+
+     pty     Permits tty allocation previously disabled by the restrict
+             option.
+
+     restrict
+             Enable all restrictions, i.e. disable port, agent and X11
+             forwarding, as well as disabling PTY allocation and execution of
+             ~/.ssh/rc.  If any future restriction capabilities are added to
+             authorized_keys files they will be included in this set.
+
+     tunnel="n"
+             Force a tun(4) device on the server.  Without this option, the
+             next available device will be used if the client requests a
+             tunnel.
+
+     user-rc
+             Enables execution of ~/.ssh/rc previously disabled by the
+             restrict option.
+
+     X11-forwarding
+             Permits X11 forwarding previously disabled by the restrict
+             option.
+
+     An example authorized_keys file:
+

+SSH_KNOWN_HOSTS FILE FORMAT
+     The /etc/ssh/ssh_known_hosts and ~/.ssh/known_hosts files contain host
+     public keys for all known hosts.  The global file should be prepared by
+     the administrator (optional), and the per-user file is maintained
+     automatically: whenever the user connects to an unknown host, its key is
+     added to the per-user file.
+
+     Each line in these files contains the following fields: markers
+     (optional), hostnames, keytype, base64-encoded key, comment.  The fields
+     are separated by spaces.
+
+     The marker is optional, but if it is present then it must be one of
+     M-bM-^@M-^\@cert-authorityM-bM-^@M-^], to indicate that the line contains a certification
+     authority (CA) key, or M-bM-^@M-^\@revokedM-bM-^@M-^], to indicate that the key contained on
+     the line is revoked and must not ever be accepted.  Only one marker
+     should be used on a key line.
+
+     Hostnames is a comma-separated list of patterns (M-bM-^@M-^X*M-bM-^@M-^Y and M-bM-^@M-^X?M-bM-^@M-^Y act as
+     wildcards); each pattern in turn is matched against the host name.  When
+     sshd is authenticating a client, such as when using
+     HostbasedAuthentication, this will be the canonical client host name.
+     When ssh(1) is authenticating a server, this will be the host name given
+     by the user, the value of the ssh(1) HostkeyAlias if it was specified, or
+     the canonical server hostname if the ssh(1) CanonicalizeHostname option
+     was used.
+
+     A pattern may also be preceded by M-bM-^@M-^X!M-bM-^@M-^Y to indicate negation: if the host
+     name matches a negated pattern, it is not accepted (by that line) even if
+     it matched another pattern on the line.  A hostname or address may
+     optionally be enclosed within M-bM-^@M-^X[M-bM-^@M-^Y and M-bM-^@M-^X]M-bM-^@M-^Y brackets then followed by M-bM-^@M-^X:M-bM-^@M-^Y
+     and a non-standard port number.
+
+     Alternately, hostnames may be stored in a hashed form which hides host
+     names and addresses should the file's contents be disclosed.  Hashed
+     hostnames start with a M-bM-^@M-^X|M-bM-^@M-^Y character.  Only one hashed hostname may
+     appear on a single line and none of the above negation or wildcard
+     operators may be applied.
+
+     The keytype and base64-encoded key are taken directly from the host key;
+     they can be obtained, for example, from /etc/ssh/ssh_host_rsa_key.pub.
+     The optional comment field continues to the end of the line, and is not
+     used.
+
+     Lines starting with M-bM-^@M-^X#M-bM-^@M-^Y and empty lines are ignored as comments.
+
+     When performing host authentication, authentication is accepted if any
+     matching line has the proper key; either one that matches exactly or, if
+     the server has presented a certificate for authentication, the key of the
+     certification authority that signed the certificate.  For a key to be
+     trusted as a certification authority, it must use the M-bM-^@M-^\@cert-authorityM-bM-^@M-^]
+     marker described above.
+
+     The known hosts file also provides a facility to mark keys as revoked,
+     for example when it is known that the associated private key has been
+     stolen.  Revoked keys are specified by including the M-bM-^@M-^\@revokedM-bM-^@M-^] marker at
+     the beginning of the key line, and are never accepted for authentication
+     or as certification authorities, but instead will produce a warning from
+     ssh(1) when they are encountered.
+
+     It is permissible (but not recommended) to have several lines or
+     different host keys for the same names.  This will inevitably happen when
+     short forms of host names from different domains are put in the file.  It
+     is possible that the files contain conflicting information;
+     authentication is accepted if valid information can be found from either
+     file.
+
+     Note that the lines in these files are typically hundreds of characters
+     long, and you definitely don't want to type in the host keys by hand.
+     Rather, generate them by a script, ssh-keyscan(1) or by taking, for
+     example, /etc/ssh/ssh_host_rsa_key.pub and adding the host names at the
+     front.  ssh-keygen(1) also offers some basic automated editing for
+     ~/.ssh/known_hosts including removing hosts matching a host name and
+     converting all host names to their hashed representations.
+
+     An example ssh_known_hosts file:
+
+        # Comments allowed at start of line
+        closenet,...,192.0.2.53 1024 37 159...93 closenet.example.net
+        cvs.example.net,192.0.2.10 ssh-rsa AAAA1234.....=
+        # A hashed hostname
+        |1|JfKTdBh7rNbXkVAQCRp4OQoPfmI=|USECr3SWf1JUPsms5AqfD5QfxkM= ssh-rsa
+        AAAA1234.....=
+        # A revoked key
+        @revoked * ssh-rsa AAAAB5W...
+        # A CA key, accepted for any host in *.mydomain.com or *.mydomain.org
+        @cert-authority *.mydomain.org,*.mydomain.com ssh-rsa AAAAB5W...
+
+FILES
+     ~/.hushlogin
+             This file is used to suppress printing the last login time and
+             /etc/motd, if PrintLastLog and PrintMotd, respectively, are
+             enabled.  It does not suppress printing of the banner specified
+             by Banner.
+
+     ~/.rhosts
+             This file is used for host-based authentication (see ssh(1) for
+             more information).  On some machines this file may need to be
+             world-readable if the user's home directory is on an NFS
+             partition, because sshd reads it as root.  Additionally, this
+             file must be owned by the user, and must not have write
+             permissions for anyone else.  The recommended permission for most
+             machines is read/write for the user, and not accessible by
+             others.
+
+     ~/.shosts
+             This file is used in exactly the same way as .rhosts, but allows
+             host-based authentication without permitting login with
+             rlogin/rsh.
+
+     ~/.ssh/
+             This directory is the default location for all user-specific
+             configuration and authentication information.  There is no
+             general requirement to keep the entire contents of this directory
+             secret, but the recommended permissions are read/write/execute
+             for the user, and not accessible by others.
+
+     ~/.ssh/authorized_keys
+             Lists the public keys (DSA, ECDSA, Ed25519, RSA) that can be used
+             for logging in as this user.  The format of this file is
+             described above.  The content of the file is not highly
+             sensitive, but the recommended permissions are read/write for the
+             user, and not accessible by others.
+
+             If this file, the ~/.ssh directory, or the user's home directory
+             are writable by other users, then the file could be modified or
+             replaced by unauthorized users.  In this case, sshd will not
+             allow it to be used unless the StrictModes option has been set to
+             M-bM-^@M-^\noM-bM-^@M-^].
+
+     ~/.ssh/environment
+             This file is read into the environment at login (if it exists).
+             It can only contain empty lines, comment lines (that start with
+             M-bM-^@M-^X#M-bM-^@M-^Y), and assignment lines of the form name=value.  The file
+             should be writable only by the user; it need not be readable by
+             anyone else.  Environment processing is disabled by default and
+             is controlled via the PermitUserEnvironment option.
+
+     ~/.ssh/known_hosts
+             Contains a list of host keys for all hosts the user has logged
+             into that are not already in the systemwide list of known host
+             keys.  The format of this file is described above.  This file
+             should be writable only by root/the owner and can, but need not
+             be, world-readable.
+
+     ~/.ssh/rc
+             Contains initialization routines to be run before the user's home
+             directory becomes accessible.  This file should be writable only
+             by the user, and need not be readable by anyone else.
+
+     /etc/hosts.equiv
+             This file is for host-based authentication (see ssh(1)).  It
+             should only be writable by root.
+
+     /etc/moduli
+             Contains Diffie-Hellman groups used for the "Diffie-Hellman Group
+             Exchange" key exchange method.  The file format is described in
+             moduli(5).  If no usable groups are found in this file then fixed
+             internal groups will be used.
+
+     /etc/motd
+             See motd(5).
+
+     /etc/nologin
+             If this file exists, sshd refuses to let anyone except root log
+             in.  The contents of the file are displayed to anyone trying to
+             log in, and non-root connections are refused.  The file should be
+             world-readable.
+
+     /etc/shosts.equiv
+             This file is used in exactly the same way as hosts.equiv, but
+             allows host-based authentication without permitting login with
+             rlogin/rsh.
+
+     /etc/ssh/ssh_host_ecdsa_key
+     /etc/ssh/ssh_host_ed25519_key
+     /etc/ssh/ssh_host_rsa_key
+             These files contain the private parts of the host keys.  These
+             files should only be owned by root, readable only by root, and
+             not accessible to others.  Note that sshd does not start if these
+             files are group/world-accessible.
+
+     /etc/ssh/ssh_host_ecdsa_key.pub
+     /etc/ssh/ssh_host_ed25519_key.pub
+     /etc/ssh/ssh_host_rsa_key.pub
+             These files contain the public parts of the host keys.  These
+             files should be world-readable but writable only by root.  Their
+             contents should match the respective private parts.  These files
+             are not really used for anything; they are provided for the
+             convenience of the user so their contents can be copied to known
+             hosts files.  These files are created using ssh-keygen(1).
+
+     /etc/ssh/ssh_known_hosts
+             Systemwide list of known host keys.  This file should be prepared
+             by the system administrator to contain the public host keys of
+             all machines in the organization.  The format of this file is
+             described above.  This file should be writable only by root/the
+             owner and should be world-readable.
+
+     /etc/ssh/sshd_config
+             Contains configuration data for sshd.  The file format and
+             configuration options are described in sshd_config(5).
+
+     /etc/ssh/sshrc
+             Similar to ~/.ssh/rc, it can be used to specify machine-specific
+             login-time initializations globally.  This file should be
+             writable only by root, and should be world-readable.
+
+     /var/empty
+             chroot(2) directory used by sshd during privilege separation in
+             the pre-authentication phase.  The directory should not contain
+             any files and must be owned by root and not group or world-
+             writable.
+
+     /var/run/sshd.pid
+             Contains the process ID of the sshd listening for connections (if
+             there are several daemons running concurrently for different
+             ports, this contains the process ID of the one started last).
+             The content of this file is not sensitive; it can be world-
+             readable.

+SSHD_CONFIG(5)                File Formats Manual               SSHD_CONFIG(5)
+
+NAME
+     sshd_config M-bM-^@M-^S OpenSSH SSH daemon configuration file
+
+DESCRIPTION
+     sshd(8) reads configuration data from /etc/ssh/sshd_config (or the file
+     specified with -f on the command line).  The file contains keyword-
+     argument pairs, one per line.  For each keyword, the first obtained value
+     will be used.  Lines starting with M-bM-^@M-^X#M-bM-^@M-^Y and empty lines are interpreted as
+     comments.  Arguments may optionally be enclosed in double quotes (") in
+     order to represent arguments containing spaces.
+
+     The possible keywords and their meanings are as follows (note that
+     keywords are case-insensitive and arguments are case-sensitive):
+
+     AcceptEnv
+             Specifies what environment variables sent by the client will be
+             copied into the session's environ(7).  See SendEnv and SetEnv in
+             ssh_config(5) for how to configure the client.  The TERM
+             environment variable is always accepted whenever the client
+             requests a pseudo-terminal as it is required by the protocol.
+             Variables are specified by name, which may contain the wildcard
+             characters M-bM-^@M-^X*M-bM-^@M-^Y and M-bM-^@M-^X?M-bM-^@M-^Y.  Multiple environment variables may be
+             separated by whitespace or spread across multiple AcceptEnv
+             directives.  Be warned that some environment variables could be
+             used to bypass restricted user environments.  For this reason,
+             care should be taken in the use of this directive.  The default
+             is not to accept any environment variables.
+
+     AddressFamily
+             Specifies which address family should be used by sshd(8).  Valid
+             arguments are any (the default), inet (use IPv4 only), or inet6
+             (use IPv6 only).
+
+     AllowAgentForwarding
+             Specifies whether ssh-agent(1) forwarding is permitted.  The
+             default is yes.  Note that disabling agent forwarding does not
+             improve security unless users are also denied shell access, as
+             they can always install their own forwarders.
+
+     AllowGroups
+             This keyword can be followed by a list of group name patterns,
+             separated by spaces.  If specified, login is allowed only for
+             users whose primary group or supplementary group list matches one
+             of the patterns.  Only group names are valid; a numerical group
+             ID is not recognized.  By default, login is allowed for all
+             groups.  The allow/deny directives are processed in the following
+             order: DenyUsers, AllowUsers, DenyGroups, and finally
+             AllowGroups.
+
+             See PATTERNS in ssh_config(5) for more information on patterns.
+
+     AllowStreamLocalForwarding
+             Specifies whether StreamLocal (Unix-domain socket) forwarding is
+             permitted.  The available options are yes (the default) or all to
+             allow StreamLocal forwarding, no to prevent all StreamLocal
+             forwarding, local to allow local (from the perspective of ssh(1))
+             forwarding only or remote to allow remote forwarding only.  Note
+             that disabling StreamLocal forwarding does not improve security
+             unless users are also denied shell access, as they can always
+             install their own forwarders.
+
+     AllowTcpForwarding
+             Specifies whether TCP forwarding is permitted.  The available
+             options are yes (the default) or all to allow TCP forwarding, no
+             to prevent all TCP forwarding, local to allow local (from the
+             perspective of ssh(1)) forwarding only or remote to allow remote
+             forwarding only.  Note that disabling TCP forwarding does not
+             improve security unless users are also denied shell access, as
+             they can always install their own forwarders.
+
+     AllowUsers
+             This keyword can be followed by a list of user name patterns,
+             separated by spaces.  If specified, login is allowed only for
+             user names that match one of the patterns.  Only user names are
+             valid; a numerical user ID is not recognized.  By default, login
+             is allowed for all users.  If the pattern takes the form
+             USER@HOST then USER and HOST are separately checked, restricting
+             logins to particular users from particular hosts.  HOST criteria
+             may additionally contain addresses to match in CIDR
+             address/masklen format.  The allow/deny directives are processed
+             in the following order: DenyUsers, AllowUsers, DenyGroups, and
+             finally AllowGroups.
+
+             See PATTERNS in ssh_config(5) for more information on patterns.
+
+     AuthenticationMethods
+             Specifies the authentication methods that must be successfully
+             completed for a user to be granted access.  This option must be
+             followed by one or more lists of comma-separated authentication
+             method names, or by the single string any to indicate the default
+             behaviour of accepting any single authentication method.  If the
+             default is overridden, then successful authentication requires
+             completion of every method in at least one of these lists.
+
+             For example, "publickey,password publickey,keyboard-interactive"
+             would require the user to complete public key authentication,
+             followed by either password or keyboard interactive
+             authentication.  Only methods that are next in one or more lists
+             are offered at each stage, so for this example it would not be
+             possible to attempt password or keyboard-interactive
+             authentication before public key.
+
+             For keyboard interactive authentication it is also possible to
+             restrict authentication to a specific device by appending a colon
+             followed by the device identifier bsdauth or pam.  depending on
+             the server configuration.  For example,
+             "keyboard-interactive:bsdauth" would restrict keyboard
+             interactive authentication to the bsdauth device.
+
+             If the publickey method is listed more than once, sshd(8)
+             verifies that keys that have been used successfully are not
+             reused for subsequent authentications.  For example,
+             "publickey,publickey" requires successful authentication using
+             two different public keys.
+
+             Note that each authentication method listed should also be
+             explicitly enabled in the configuration.
+
+             The available authentication methods are: "gssapi-with-mic",
+             "hostbased", "keyboard-interactive", "none" (used for access to
+             password-less accounts when PermitEmptyPasswords is enabled),
+             "password" and "publickey".
+
+     AuthorizedKeysCommand
+             Specifies a program to be used to look up the user's public keys.
+             The program must be owned by root, not writable by group or
+             others and specified by an absolute path.  Arguments to
+             AuthorizedKeysCommand accept the tokens described in the TOKENS
+             section.  If no arguments are specified then the username of the
+             target user is used.
+
+             The program should produce on standard output zero or more lines
+             of authorized_keys output (see AUTHORIZED_KEYS in sshd(8)).  If a
+             key supplied by AuthorizedKeysCommand does not successfully
+             authenticate and authorize the user then public key
+             authentication continues using the usual AuthorizedKeysFile
+             files.  By default, no AuthorizedKeysCommand is run.
+
+     AuthorizedKeysCommandUser
+             Specifies the user under whose account the AuthorizedKeysCommand
+             is run.  It is recommended to use a dedicated user that has no
+             other role on the host than running authorized keys commands.  If
+             AuthorizedKeysCommand is specified but AuthorizedKeysCommandUser
+             is not, then sshd(8) will refuse to start.
+
+     AuthorizedKeysFile
+             Specifies the file that contains the public keys used for user
+             authentication.  The format is described in the AUTHORIZED_KEYS
+             FILE FORMAT section of sshd(8).  Arguments to AuthorizedKeysFile
+             accept the tokens described in the TOKENS section.  After
+             expansion, AuthorizedKeysFile is taken to be an absolute path or
+             one relative to the user's home directory.  Multiple files may be
+             listed, separated by whitespace.  Alternately this option may be
+             set to none to skip checking for user keys in files.  The default
+             is ".ssh/authorized_keys .ssh/authorized_keys2".
+
+     AuthorizedPrincipalsCommand
+             Specifies a program to be used to generate the list of allowed
+             certificate principals as per AuthorizedPrincipalsFile.  The
+             program must be owned by root, not writable by group or others
+             and specified by an absolute path.  Arguments to
+             AuthorizedPrincipalsCommand accept the tokens described in the
+             TOKENS section.  If no arguments are specified then the username
+             of the target user is used.
+
+             The program should produce on standard output zero or more lines
+             of AuthorizedPrincipalsFile output.  If either
+             AuthorizedPrincipalsCommand or AuthorizedPrincipalsFile is
+             specified, then certificates offered by the client for
+             authentication must contain a principal that is listed.  By
+             default, no AuthorizedPrincipalsCommand is run.
+
+     AuthorizedPrincipalsCommandUser
+             Specifies the user under whose account the
+             AuthorizedPrincipalsCommand is run.  It is recommended to use a
+             dedicated user that has no other role on the host than running
+             authorized principals commands.  If AuthorizedPrincipalsCommand
+             is specified but AuthorizedPrincipalsCommandUser is not, then
+             sshd(8) will refuse to start.
+
+     AuthorizedPrincipalsFile
+             Specifies a file that lists principal names that are accepted for
+             certificate authentication.  When using certificates signed by a
+             key listed in TrustedUserCAKeys, this file lists names, one of
+             which must appear in the certificate for it to be accepted for
+             authentication.  Names are listed one per line preceded by key
+             options (as described in AUTHORIZED_KEYS FILE FORMAT in sshd(8)).
+             Empty lines and comments starting with M-bM-^@M-^X#M-bM-^@M-^Y are ignored.
+
+             Arguments to AuthorizedPrincipalsFile accept the tokens described
+             in the TOKENS section.  After expansion, AuthorizedPrincipalsFile
+             is taken to be an absolute path or one relative to the user's
+             home directory.  The default is none, i.e. not to use a
+             principals file M-bM-^@M-^S in this case, the username of the user must
+             appear in a certificate's principals list for it to be accepted.
+
+             Note that AuthorizedPrincipalsFile is only used when
+             authentication proceeds using a CA listed in TrustedUserCAKeys
+             and is not consulted for certification authorities trusted via
+             ~/.ssh/authorized_keys, though the principals= key option offers
+             a similar facility (see sshd(8) for details).
+
+     Banner  The contents of the specified file are sent to the remote user
+             before authentication is allowed.  If the argument is none then
+             no banner is displayed.  By default, no banner is displayed.
+
+     CASignatureAlgorithms
+             Specifies which algorithms are allowed for signing of
+             certificates by certificate authorities (CAs).  The default is:
+
+                   ecdsa-sha2-nistp256.ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
+                   ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa
+
+             Certificates signed using other algorithms will not be accepted
+             for public key or host-based authentication.
+
+     ChallengeResponseAuthentication
+             Specifies whether challenge-response authentication is allowed
+             (e.g. via PAM or through authentication styles supported in
+             login.conf(5)) The default is yes.
+
+     ChrootDirectory
+             Specifies the pathname of a directory to chroot(2) to after
+             authentication.  At session startup sshd(8) checks that all
+             components of the pathname are root-owned directories which are
+             not writable by any other user or group.  After the chroot,
+             sshd(8) changes the working directory to the user's home
+             directory.  Arguments to ChrootDirectory accept the tokens
+             described in the TOKENS section.
+
+             The ChrootDirectory must contain the necessary files and
+             directories to support the user's session.  For an interactive
+             session this requires at least a shell, typically sh(1), and
+             basic /dev nodes such as null(4), zero(4), stdin(4), stdout(4),
+             stderr(4), and tty(4) devices.  For file transfer sessions using
+             SFTP no additional configuration of the environment is necessary
+             if the in-process sftp-server is used, though sessions which use
+             logging may require /dev/log inside the chroot directory on some
+             operating systems (see sftp-server(8) for details).
+
+             For safety, it is very important that the directory hierarchy be
+             prevented from modification by other processes on the system
+             (especially those outside the jail).  Misconfiguration can lead
+             to unsafe environments which sshd(8) cannot detect.
+
+             The default is none, indicating not to chroot(2).
+
+     Ciphers
+             Specifies the ciphers allowed.  Multiple ciphers must be comma-
+             separated.  If the specified value begins with a M-bM-^@M-^X+M-bM-^@M-^Y character,
+             then the specified ciphers will be appended to the default set
+             instead of replacing them.  If the specified value begins with a
+             M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified ciphers (including wildcards)
+             will be removed from the default set instead of replacing them.
+
+             The supported ciphers are:
+
+                   3des-cbc
+                   aes128-cbc
+                   aes192-cbc
+                   aes256-cbc
+                   aes128-ctr
+                   aes192-ctr
+                   aes256-ctr
+                   aes128-gcm@openssh.com
+                   aes256-gcm@openssh.com
+                   chacha20-poly1305@openssh.com
+
+             The default is:
+
+                   chacha20-poly1305@openssh.com,
+                   aes128-ctr,aes192-ctr,aes256-ctr,
+                   aes128-gcm@openssh.com,aes256-gcm@openssh.com
+
+             The list of available ciphers may also be obtained using "ssh -Q
+             cipher".
+
+     ClientAliveCountMax
+             Sets the number of client alive messages which may be sent
+             without sshd(8) receiving any messages back from the client.  If
+             this threshold is reached while client alive messages are being
+             sent, sshd will disconnect the client, terminating the session.
+             It is important to note that the use of client alive messages is
+             very different from TCPKeepAlive.  The client alive messages are
+             sent through the encrypted channel and therefore will not be
+             spoofable.  The TCP keepalive option enabled by TCPKeepAlive is
+             spoofable.  The client alive mechanism is valuable when the
+             client or server depend on knowing when a connection has become
+             inactive.
+
+             The default value is 3.  If ClientAliveInterval is set to 15, and
+             ClientAliveCountMax is left at the default, unresponsive SSH
+             clients will be disconnected after approximately 45 seconds.
+
+     ClientAliveInterval
+             Sets a timeout interval in seconds after which if no data has
+             been received from the client, sshd(8) will send a message
+             through the encrypted channel to request a response from the
+             client.  The default is 0, indicating that these messages will
+             not be sent to the client.
+
+     Compression
+             Specifies whether compression is enabled after the user has
+             authenticated successfully.  The argument must be yes, delayed (a
+             legacy synonym for yes) or no.  The default is yes.
+
+     DenyGroups
+             This keyword can be followed by a list of group name patterns,
+             separated by spaces.  Login is disallowed for users whose primary
+             group or supplementary group list matches one of the patterns.
+             Only group names are valid; a numerical group ID is not
+             recognized.  By default, login is allowed for all groups.  The
+             allow/deny directives are processed in the following order:
+             DenyUsers, AllowUsers, DenyGroups, and finally AllowGroups.
+
+             See PATTERNS in ssh_config(5) for more information on patterns.
+
+     DenyUsers
+             This keyword can be followed by a list of user name patterns,
+             separated by spaces.  Login is disallowed for user names that
+             match one of the patterns.  Only user names are valid; a
+             numerical user ID is not recognized.  By default, login is
+             allowed for all users.  If the pattern takes the form USER@HOST
+             then USER and HOST are separately checked, restricting logins to
+             particular users from particular hosts.  HOST criteria may
+             additionally contain addresses to match in CIDR address/masklen
+             format.  The allow/deny directives are processed in the following
+             order: DenyUsers, AllowUsers, DenyGroups, and finally
+             AllowGroups.
+
+             See PATTERNS in ssh_config(5) for more information on patterns.
+
+     DisableForwarding
+             Disables all forwarding features, including X11, ssh-agent(1),
+             TCP and StreamLocal.  This option overrides all other forwarding-
+             related options and may simplify restricted configurations.
+
+     ExposeAuthInfo
+             Writes a temporary file containing a list of authentication
+             methods and public credentials (e.g. keys) used to authenticate
+             the user.  The location of the file is exposed to the user
+             session through the SSH_USER_AUTH environment variable.  The
+             default is no.
+
+     FingerprintHash
+             Specifies the hash algorithm used when logging key fingerprints.
+             Valid options are: md5 and sha256.  The default is sha256.
+
+     ForceCommand
+             Forces the execution of the command specified by ForceCommand,
+             ignoring any command supplied by the client and ~/.ssh/rc if
+             present.  The command is invoked by using the user's login shell
+             with the -c option.  This applies to shell, command, or subsystem
+             execution.  It is most useful inside a Match block.  The command
+             originally supplied by the client is available in the
+             SSH_ORIGINAL_COMMAND environment variable.  Specifying a command
+             of internal-sftp will force the use of an in-process SFTP server
+             that requires no support files when used with ChrootDirectory.
+             The default is none.
+
+     GatewayPorts
+             Specifies whether remote hosts are allowed to connect to ports
+             forwarded for the client.  By default, sshd(8) binds remote port
+             forwardings to the loopback address.  This prevents other remote
+             hosts from connecting to forwarded ports.  GatewayPorts can be
+             used to specify that sshd should allow remote port forwardings to
+             bind to non-loopback addresses, thus allowing other hosts to
+             connect.  The argument may be no to force remote port forwardings
+             to be available to the local host only, yes to force remote port
+             forwardings to bind to the wildcard address, or clientspecified
+             to allow the client to select the address to which the forwarding
+             is bound.  The default is no.
+
+     GSSAPIAuthentication
+             Specifies whether user authentication based on GSSAPI is allowed.
+             The default is no.
+
+     GSSAPICleanupCredentials
+             Specifies whether to automatically destroy the user's credentials
+             cache on logout.  The default is yes.
+
+     GSSAPIStrictAcceptorCheck
+             Determines whether to be strict about the identity of the GSSAPI
+             acceptor a client authenticates against.  If set to yes then the
+             client must authenticate against the host service on the current
+             hostname.  If set to no then the client may authenticate against
+             any service key stored in the machine's default store.  This
+             facility is provided to assist with operation on multi homed
+             machines.  The default is yes.
+
+     HostbasedAcceptedKeyTypes
+             Specifies the key types that will be accepted for hostbased
+             authentication as a list of comma-separated patterns.
+             Alternately if the specified value begins with a M-bM-^@M-^X+M-bM-^@M-^Y character,
+             then the specified key types will be appended to the default set
+             instead of replacing them.  If the specified value begins with a
+             M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified key types (including wildcards)
+             will be removed from the default set instead of replacing them.
+             The default for this option is:
+
+                ecdsa-sha2-nistp256-cert-v01@openssh.com,
+                ecdsa-sha2-nistp384-cert-v01@openssh.com,
+                ecdsa-sha2-nistp521-cert-v01@openssh.com,
+                ssh-ed25519-cert-v01@openssh.com,
+                rsa-sha2-512-cert-v01@openssh.com,rsa-sha2-256-cert-v01@openssh.com,
+                ssh-rsa-cert-v01@openssh.com,
+                ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
+                ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa
+
+             The list of available key types may also be obtained using "ssh
+             -Q key".
+
+     HostbasedAuthentication
+             Specifies whether rhosts or /etc/hosts.equiv authentication
+             together with successful public key client host authentication is
+             allowed (host-based authentication).  The default is no.
+
+     HostbasedUsesNameFromPacketOnly
+             Specifies whether or not the server will attempt to perform a
+             reverse name lookup when matching the name in the ~/.shosts,
+             ~/.rhosts, and /etc/hosts.equiv files during
+             HostbasedAuthentication.  A setting of yes means that sshd(8)
+             uses the name supplied by the client rather than attempting to
+             resolve the name from the TCP connection itself.  The default is
+             no.
+
+     HostCertificate
+             Specifies a file containing a public host certificate.  The
+             certificate's public key must match a private host key already
+             specified by HostKey.  The default behaviour of sshd(8) is not to
+             load any certificates.
+
+     HostKey
+             Specifies a file containing a private host key used by SSH.  The
+             defaults are /etc/ssh/ssh_host_ecdsa_key,
+             /etc/ssh/ssh_host_ed25519_key and /etc/ssh/ssh_host_rsa_key.
+
+             Note that sshd(8) will refuse to use a file if it is group/world-
+             accessible and that the HostKeyAlgorithms option restricts which
+             of the keys are actually used by sshd(8).
+
+             It is possible to have multiple host key files.  It is also
+             possible to specify public host key files instead.  In this case
+             operations on the private key will be delegated to an
+             ssh-agent(1).
+
+     HostKeyAgent
+             Identifies the UNIX-domain socket used to communicate with an
+             agent that has access to the private host keys.  If the string
+             "SSH_AUTH_SOCK" is specified, the location of the socket will be
+             read from the SSH_AUTH_SOCK environment variable.
+
+     HostKeyAlgorithms
+             Specifies the host key algorithms that the server offers.  The
+             default for this option is:
+
+                ecdsa-sha2-nistp256-cert-v01@openssh.com,
+                ecdsa-sha2-nistp384-cert-v01@openssh.com,
+                ecdsa-sha2-nistp521-cert-v01@openssh.com,
+                ssh-ed25519-cert-v01@openssh.com,
+                rsa-sha2-512-cert-v01@openssh.com,rsa-sha2-256-cert-v01@openssh.com,
+                ssh-rsa-cert-v01@openssh.com,
+                ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
+                ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa
+
+             The list of available key types may also be obtained using "ssh
+             -Q key".
+
+     IgnoreRhosts
+             Specifies that .rhosts and .shosts files will not be used in
+             HostbasedAuthentication.
+
+             /etc/hosts.equiv and /etc/shosts.equiv are still used.  The
+             default is yes.
+
+     IgnoreUserKnownHosts
+             Specifies whether sshd(8) should ignore the user's
+             ~/.ssh/known_hosts during HostbasedAuthentication and use only
+             the system-wide known hosts file /etc/ssh/known_hosts.  The
+             default is no.
+
+     IPQoS   Specifies the IPv4 type-of-service or DSCP class for the
+             connection.  Accepted values are af11, af12, af13, af21, af22,
+             af23, af31, af32, af33, af41, af42, af43, cs0, cs1, cs2, cs3,
+             cs4, cs5, cs6, cs7, ef, lowdelay, throughput, reliability, a
+             numeric value, or none to use the operating system default.  This
+             option may take one or two arguments, separated by whitespace.
+             If one argument is specified, it is used as the packet class
+             unconditionally.  If two values are specified, the first is
+             automatically selected for interactive sessions and the second
+             for non-interactive sessions.  The default is af21 (Low-Latency
+             Data) for interactive sessions and cs1 (Lower Effort) for non-
+             interactive sessions.
+
+     KbdInteractiveAuthentication
+             Specifies whether to allow keyboard-interactive authentication.
+             The argument to this keyword must be yes or no.  The default is
+             to use whatever value ChallengeResponseAuthentication is set to
+             (by default yes).
+
+     KerberosAuthentication
+             Specifies whether the password provided by the user for
+             PasswordAuthentication will be validated through the Kerberos
+             KDC.  To use this option, the server needs a Kerberos servtab
+             which allows the verification of the KDC's identity.  The default
+             is no.
+
+     KerberosGetAFSToken
+             If AFS is active and the user has a Kerberos 5 TGT, attempt to
+             acquire an AFS token before accessing the user's home directory.
+             The default is no.
+
+     KerberosOrLocalPasswd
+             If password authentication through Kerberos fails then the
+             password will be validated via any additional local mechanism
+             such as /etc/passwd.  The default is yes.
+
+     KerberosTicketCleanup
+             Specifies whether to automatically destroy the user's ticket
+             cache file on logout.  The default is yes.
+
+     KexAlgorithms
+             Specifies the available KEX (Key Exchange) algorithms.  Multiple
+             algorithms must be comma-separated.  Alternately if the specified
+             value begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified methods
+             will be appended to the default set instead of replacing them.
+             If the specified value begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the
+             specified methods (including wildcards) will be removed from the
+             default set instead of replacing them.  The supported algorithms
+             are:
+
+                   curve25519-sha256
+                   curve25519-sha256@libssh.org
+                   diffie-hellman-group1-sha1
+                   diffie-hellman-group14-sha1
+                   diffie-hellman-group14-sha256
+                   diffie-hellman-group16-sha512
+                   diffie-hellman-group18-sha512

+                   ecdh-sha2-nistp384
+                   ecdh-sha2-nistp521
+
+             The default is:
+
+                   curve25519-sha256,curve25519-sha256@libssh.org,
+                   ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,

+                   diffie-hellman-group14-sha256,diffie-hellman-group14-sha1
+
+             The list of available key exchange algorithms may also be
+             obtained using "ssh -Q kex".
+
+     ListenAddress
+             Specifies the local addresses sshd(8) should listen on.  The
+             following forms may be used:
+
+                   ListenAddress hostname|address [rdomain domain]
+                   ListenAddress hostname:port [rdomain domain]
+                   ListenAddress IPv4_address:port [rdomain domain]
+                   ListenAddress [hostname|address]:port [rdomain domain]
+
+             The optional rdomain qualifier requests sshd(8) listen in an
+             explicit routing domain.  If port is not specified, sshd will
+             listen on the address and all Port options specified.  The
+             default is to listen on all local addresses on the current
+             default routing domain.  Multiple ListenAddress options are
+             permitted.  For more information on routing domains, see
+             rdomain(4).
+
+     LoginGraceTime
+             The server disconnects after this time if the user has not
+             successfully logged in.  If the value is 0, there is no time
+             limit.  The default is 120 seconds.
+
+     LogLevel
+             Gives the verbosity level that is used when logging messages from
+             sshd(8).  The possible values are: QUIET, FATAL, ERROR, INFO,
+             VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3.  The default is INFO.
+             DEBUG and DEBUG1 are equivalent.  DEBUG2 and DEBUG3 each specify
+             higher levels of debugging output.  Logging with a DEBUG level
+             violates the privacy of users and is not recommended.
+
+     MACs    Specifies the available MAC (message authentication code)
+             algorithms.  The MAC algorithm is used for data integrity
+             protection.  Multiple algorithms must be comma-separated.  If the
+             specified value begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified
+             algorithms will be appended to the default set instead of
+             replacing them.  If the specified value begins with a M-bM-^@M-^X-M-bM-^@M-^Y
+             character, then the specified algorithms (including wildcards)
+             will be removed from the default set instead of replacing them.
+
+             The algorithms that contain "-etm" calculate the MAC after
+             encryption (encrypt-then-mac).  These are considered safer and
+             their use recommended.  The supported MACs are:
+
+                   hmac-md5
+                   hmac-md5-96
+                   hmac-sha1
+                   hmac-sha1-96
+                   hmac-sha2-256
+                   hmac-sha2-512
+                   umac-64@openssh.com
+                   umac-128@openssh.com
+                   hmac-md5-etm@openssh.com
+                   hmac-md5-96-etm@openssh.com
+                   hmac-sha1-etm@openssh.com
+                   hmac-sha1-96-etm@openssh.com
+                   hmac-sha2-256-etm@openssh.com
+                   hmac-sha2-512-etm@openssh.com
+                   umac-64-etm@openssh.com
+                   umac-128-etm@openssh.com
+
+             The default is:
+
+                   umac-64-etm@openssh.com,umac-128-etm@openssh.com,
+                   hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com,
+                   hmac-sha1-etm@openssh.com,
+                   umac-64@openssh.com,umac-128@openssh.com,
+                   hmac-sha2-256,hmac-sha2-512,hmac-sha1
+
+             The list of available MAC algorithms may also be obtained using
+             "ssh -Q mac".
+
+     Match   Introduces a conditional block.  If all of the criteria on the
+             Match line are satisfied, the keywords on the following lines
+             override those set in the global section of the config file,
+             until either another Match line or the end of the file.  If a
+             keyword appears in multiple Match blocks that are satisfied, only
+             the first instance of the keyword is applied.
+
+             The arguments to Match are one or more criteria-pattern pairs or
+             the single token All which matches all criteria.  The available
+             criteria are User, Group, Host, LocalAddress, LocalPort, RDomain,
+             and Address (with RDomain representing the rdomain(4) on which
+             the connection was received.)
+
+             The match patterns may consist of single entries or comma-
+             separated lists and may use the wildcard and negation operators
+             described in the PATTERNS section of ssh_config(5).
+
+             The patterns in an Address criteria may additionally contain
+             addresses to match in CIDR address/masklen format, such as
+             192.0.2.0/24 or 2001:db8::/32.  Note that the mask length
+             provided must be consistent with the address - it is an error to
+             specify a mask length that is too long for the address or one
+             with bits set in this host portion of the address.  For example,
+             192.0.2.0/33 and 192.0.2.0/8, respectively.
+
+             Only a subset of keywords may be used on the lines following a
+             Match keyword.  Available keywords are AcceptEnv,
+             AllowAgentForwarding, AllowGroups, AllowStreamLocalForwarding,
+             AllowTcpForwarding, AllowUsers, AuthenticationMethods,
+             AuthorizedKeysCommand, AuthorizedKeysCommandUser,
+             AuthorizedKeysFile, AuthorizedPrincipalsCommand,
+             AuthorizedPrincipalsCommandUser, AuthorizedPrincipalsFile,
+             Banner, ChrootDirectory, ClientAliveCountMax,
+             ClientAliveInterval, DenyGroups, DenyUsers, ForceCommand,
+             GatewayPorts, GSSAPIAuthentication, HostbasedAcceptedKeyTypes,
+             HostbasedAuthentication, HostbasedUsesNameFromPacketOnly, IPQoS,
+             KbdInteractiveAuthentication, KerberosAuthentication, LogLevel,
+             MaxAuthTries, MaxSessions, PasswordAuthentication,
+             PermitEmptyPasswords, PermitListen, PermitOpen, PermitRootLogin,
+             PermitTTY, PermitTunnel, PermitUserRC, PubkeyAcceptedKeyTypes,
+             PubkeyAuthentication, RekeyLimit, RevokedKeys, RDomain, SetEnv,
+             StreamLocalBindMask, StreamLocalBindUnlink, TrustedUserCAKeys,
+             X11DisplayOffset, X11Forwarding and X11UseLocalHost.
+
+     MaxAuthTries
+             Specifies the maximum number of authentication attempts permitted
+             per connection.  Once the number of failures reaches half this
+             value, additional failures are logged.  The default is 6.
+
+     MaxSessions
+             Specifies the maximum number of open shell, login or subsystem
+             (e.g. sftp) sessions permitted per network connection.  Multiple
+             sessions may be established by clients that support connection
+             multiplexing.  Setting MaxSessions to 1 will effectively disable
+             session multiplexing, whereas setting it to 0 will prevent all
+             shell, login and subsystem sessions while still permitting
+             forwarding.  The default is 10.
+
+     MaxStartups
+             Specifies the maximum number of concurrent unauthenticated
+             connections to the SSH daemon.  Additional connections will be
+             dropped until authentication succeeds or the LoginGraceTime
+             expires for a connection.  The default is 10:30:100.
+
+             Alternatively, random early drop can be enabled by specifying the
+             three colon separated values start:rate:full (e.g. "10:30:60").
+             sshd(8) will refuse connection attempts with a probability of
+             rate/100 (30%) if there are currently start (10) unauthenticated
+             connections.  The probability increases linearly and all
+             connection attempts are refused if the number of unauthenticated
+             connections reaches full (60).
+
+     PasswordAuthentication
+             Specifies whether password authentication is allowed.  The
+             default is yes.
+
+     PermitEmptyPasswords
+             When password authentication is allowed, it specifies whether the
+             server allows login to accounts with empty password strings.  The
+             default is no.
+
+     PermitListen
+             Specifies the addresses/ports on which a remote TCP port
+             forwarding may listen.  The listen specification must be one of
+             the following forms:
+
+                   PermitListen port
+                   PermitListen host:port
+
+             Multiple permissions may be specified by separating them with
+             whitespace.  An argument of any can be used to remove all
+             restrictions and permit any listen requests.  An argument of none
+             can be used to prohibit all listen requests.  The host name may
+             contain wildcards as described in the PATTERNS section in
+             ssh_config(5).  The wildcard M-bM-^@M-^X*M-bM-^@M-^Y can also be used in place of a
+             port number to allow all ports.  By default all port forwarding
+             listen requests are permitted.  Note that the GatewayPorts option
+             may further restrict which addresses may be listened on.  Note
+             also that ssh(1) will request a listen host of M-bM-^@M-^\localhostM-bM-^@M-^] if no
+             listen host was specifically requested, and this this name is
+             treated differently to explicit localhost addresses of
+             M-bM-^@M-^\127.0.0.1M-bM-^@M-^] and M-bM-^@M-^\::1M-bM-^@M-^].
+
+     PermitOpen
+             Specifies the destinations to which TCP port forwarding is
+             permitted.  The forwarding specification must be one of the
+             following forms:
+
+                   PermitOpen host:port
+                   PermitOpen IPv4_addr:port
+                   PermitOpen [IPv6_addr]:port
+
+             Multiple forwards may be specified by separating them with
+             whitespace.  An argument of any can be used to remove all
+             restrictions and permit any forwarding requests.  An argument of
+             none can be used to prohibit all forwarding requests.  The
+             wildcard M-bM-^@M-^X*M-bM-^@M-^Y can be used for host or port to allow all hosts or
+             ports, respectively.  By default all port forwarding requests are
+             permitted.
+
+     PermitRootLogin
+             Specifies whether root can log in using ssh(1).  The argument
+             must be yes, prohibit-password, forced-commands-only, or no.  The
+             default is prohibit-password.
+
+             If this option is set to prohibit-password (or its deprecated
+             alias, without-password), password and keyboard-interactive
+             authentication are disabled for root.
+
+             If this option is set to forced-commands-only, root login with
+             public key authentication will be allowed, but only if the
+             command option has been specified (which may be useful for taking
+             remote backups even if root login is normally not allowed).  All
+             other authentication methods are disabled for root.
+
+             If this option is set to no, root is not allowed to log in.
+
+     PermitTTY
+             Specifies whether pty(4) allocation is permitted.  The default is
+             yes.
+
+     PermitTunnel
+             Specifies whether tun(4) device forwarding is allowed.  The
+             argument must be yes, point-to-point (layer 3), ethernet (layer
+             2), or no.  Specifying yes permits both point-to-point and
+             ethernet.  The default is no.
+
+             Independent of this setting, the permissions of the selected
+             tun(4) device must allow access to the user.
+
+     PermitUserEnvironment
+             Specifies whether ~/.ssh/environment and environment= options in
+             ~/.ssh/authorized_keys are processed by sshd(8).  Valid options
+             are yes, no or a pattern-list specifying which environment
+             variable names to accept (for example "LANG,LC_*").  The default
+             is no.  Enabling environment processing may enable users to
+             bypass access restrictions in some configurations using
+             mechanisms such as LD_PRELOAD.
+
+     PermitUserRC
+             Specifies whether any ~/.ssh/rc file is executed.  The default is
+             yes.
+
+     PidFile
+             Specifies the file that contains the process ID of the SSH
+             daemon, or none to not write one.  The default is
+             /var/run/sshd.pid.
+
+     Port    Specifies the port number that sshd(8) listens on.  The default
+             is 22.  Multiple options of this type are permitted.  See also
+             ListenAddress.
+
+     PrintLastLog
+             Specifies whether sshd(8) should print the date and time of the
+             last user login when a user logs in interactively.  The default
+             is yes.
+
+     PrintMotd
+             Specifies whether sshd(8) should print /etc/motd when a user logs
+             in interactively.  (On some systems it is also printed by the
+             shell, /etc/profile, or equivalent.)  The default is yes.
+
+     PubkeyAcceptedKeyTypes
+             Specifies the key types that will be accepted for public key
+             authentication as a list of comma-separated patterns.
+             Alternately if the specified value begins with a M-bM-^@M-^X+M-bM-^@M-^Y character,
+             then the specified key types will be appended to the default set
+             instead of replacing them.  If the specified value begins with a
+             M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified key types (including wildcards)
+             will be removed from the default set instead of replacing them.
+             The default for this option is:
+
+                ecdsa-sha2-nistp256-cert-v01@openssh.com,
+                ecdsa-sha2-nistp384-cert-v01@openssh.com,
+                ecdsa-sha2-nistp521-cert-v01@openssh.com,

+                ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa
+
+             The list of available key types may also be obtained using "ssh
+             -Q key".
+
+     PubkeyAuthentication
+             Specifies whether public key authentication is allowed.  The
+             default is yes.
+
+     RekeyLimit
+             Specifies the maximum amount of data that may be transmitted
+             before the session key is renegotiated, optionally followed a
+             maximum amount of time that may pass before the session key is
+             renegotiated.  The first argument is specified in bytes and may
+             have a suffix of M-bM-^@M-^XKM-bM-^@M-^Y, M-bM-^@M-^XMM-bM-^@M-^Y, or M-bM-^@M-^XGM-bM-^@M-^Y to indicate Kilobytes,
+             Megabytes, or Gigabytes, respectively.  The default is between
+             M-bM-^@M-^X1GM-bM-^@M-^Y and M-bM-^@M-^X4GM-bM-^@M-^Y, depending on the cipher.  The optional second
+             value is specified in seconds and may use any of the units
+             documented in the TIME FORMATS section.  The default value for
+             RekeyLimit is default none, which means that rekeying is
+             performed after the cipher's default amount of data has been sent
+             or received and no time based rekeying is done.
+
+     RevokedKeys
+             Specifies revoked public keys file, or none to not use one.  Keys
+             listed in this file will be refused for public key
+             authentication.  Note that if this file is not readable, then
+             public key authentication will be refused for all users.  Keys
+             may be specified as a text file, listing one public key per line,
+             or as an OpenSSH Key Revocation List (KRL) as generated by
+             ssh-keygen(1).  For more information on KRLs, see the KEY
+             REVOCATION LISTS section in ssh-keygen(1).
+
+     RDomain
+             Specifies an explicit routing domain that is applied after
+             authentication has completed.  The user session, as well and any
+             forwarded or listening IP sockets, will be bound to this
+             rdomain(4).  If the routing domain is set to %D, then the domain
+             in which the incoming connection was received will be applied.
+
+     SetEnv  Specifies one or more environment variables to set in child
+             sessions started by sshd(8) as M-bM-^@M-^\NAME=VALUEM-bM-^@M-^].  The environment
+             value may be quoted (e.g. if it contains whitespace characters).
+             Environment variables set by SetEnv override the default
+             environment and any variables specified by the user via AcceptEnv
+             or PermitUserEnvironment.
+
+     StreamLocalBindMask
+             Sets the octal file creation mode mask (umask) used when creating
+             a Unix-domain socket file for local or remote port forwarding.
+             This option is only used for port forwarding to a Unix-domain
+             socket file.
+
+             The default value is 0177, which creates a Unix-domain socket
+             file that is readable and writable only by the owner.  Note that
+             not all operating systems honor the file mode on Unix-domain
+             socket files.
+
+     StreamLocalBindUnlink
+             Specifies whether to remove an existing Unix-domain socket file
+             for local or remote port forwarding before creating a new one.
+             If the socket file already exists and StreamLocalBindUnlink is
+             not enabled, sshd will be unable to forward the port to the Unix-
+             domain socket file.  This option is only used for port forwarding
+             to a Unix-domain socket file.
+
+             The argument must be yes or no.  The default is no.
+
+     StrictModes
+             Specifies whether sshd(8) should check file modes and ownership
+             of the user's files and home directory before accepting login.
+             This is normally desirable because novices sometimes accidentally
+             leave their directory or files world-writable.  The default is
+             yes.  Note that this does not apply to ChrootDirectory, whose
+             permissions and ownership are checked unconditionally.
+
+     Subsystem
+             Configures an external subsystem (e.g. file transfer daemon).
+             Arguments should be a subsystem name and a command (with optional
+             arguments) to execute upon subsystem request.
+
+             The command sftp-server implements the SFTP file transfer
+             subsystem.
+
+             Alternately the name internal-sftp implements an in-process SFTP
+             server.  This may simplify configurations using ChrootDirectory
+             to force a different filesystem root on clients.
+
+             By default no subsystems are defined.
+
+     SyslogFacility
+             Gives the facility code that is used when logging messages from
+             sshd(8).  The possible values are: DAEMON, USER, AUTH, LOCAL0,
+             LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.  The
+             default is AUTH.
+
+     TCPKeepAlive
+             Specifies whether the system should send TCP keepalive messages
+             to the other side.  If they are sent, death of the connection or
+             crash of one of the machines will be properly noticed.  However,
+             this means that connections will die if the route is down
+             temporarily, and some people find it annoying.  On the other
+             hand, if TCP keepalives are not sent, sessions may hang
+             indefinitely on the server, leaving "ghost" users and consuming
+             server resources.
+
+             The default is yes (to send TCP keepalive messages), and the
+             server will notice if the network goes down or the client host
+             crashes.  This avoids infinitely hanging sessions.
+
+             To disable TCP keepalive messages, the value should be set to no.
+
+     TrustedUserCAKeys
+             Specifies a file containing public keys of certificate
+             authorities that are trusted to sign user certificates for
+             authentication, or none to not use one.  Keys are listed one per
+             line; empty lines and comments starting with M-bM-^@M-^X#M-bM-^@M-^Y are allowed.  If
+             a certificate is presented for authentication and has its signing
+             CA key listed in this file, then it may be used for
+             authentication for any user listed in the certificate's
+             principals list.  Note that certificates that lack a list of
+             principals will not be permitted for authentication using
+             TrustedUserCAKeys.  For more details on certificates, see the
+             CERTIFICATES section in ssh-keygen(1).
+
+     UseDNS  Specifies whether sshd(8) should look up the remote host name,
+             and to check that the resolved host name for the remote IP
+             address maps back to the very same IP address.
+
+             If this option is set to no (the default) then only addresses and
+             not host names may be used in ~/.ssh/authorized_keys from and
+             sshd_config Match Host directives.
+
+     UsePAM  Enables the Pluggable Authentication Module interface.  If set to
+             yes this will enable PAM authentication using
+             ChallengeResponseAuthentication and PasswordAuthentication in
+             addition to PAM account and session module processing for all
+             authentication types.
+
+             Because PAM challenge-response authentication usually serves an
+             equivalent role to password authentication, you should disable
+             either PasswordAuthentication or ChallengeResponseAuthentication.
+
+             If UsePAM is enabled, you will not be able to run sshd(8) as a
+             non-root user.  The default is no.
+
+     VersionAddendum
+             Optionally specifies additional text to append to the SSH
+             protocol banner sent by the server upon connection.  The default
+             is none.
+
+     X11DisplayOffset
+             Specifies the first display number available for sshd(8)'s X11
+             forwarding.  This prevents sshd from interfering with real X11
+             servers.  The default is 10.
+
+     X11Forwarding
+             Specifies whether X11 forwarding is permitted.  The argument must
+             be yes or no.  The default is no.
+
+             When X11 forwarding is enabled, there may be additional exposure
+             to the server and to client displays if the sshd(8) proxy display
+             is configured to listen on the wildcard address (see
+             X11UseLocalhost), though this is not the default.  Additionally,
+             the authentication spoofing and authentication data verification
+             and substitution occur on the client side.  The security risk of
+             using X11 forwarding is that the client's X11 display server may
+             be exposed to attack when the SSH client requests forwarding (see
+             the warnings for ForwardX11 in ssh_config(5)).  A system
+             administrator may have a stance in which they want to protect
+             clients that may expose themselves to attack by unwittingly
+             requesting X11 forwarding, which can warrant a no setting.
+
+             Note that disabling X11 forwarding does not prevent users from
+             forwarding X11 traffic, as users can always install their own
+             forwarders.
+
+     X11UseLocalhost
+             Specifies whether sshd(8) should bind the X11 forwarding server
+             to the loopback address or to the wildcard address.  By default,
+             sshd binds the forwarding server to the loopback address and sets
+             the hostname part of the DISPLAY environment variable to
+             localhost.  This prevents remote hosts from connecting to the
+             proxy display.  However, some older X11 clients may not function
+             with this configuration.  X11UseLocalhost may be set to no to
+             specify that the forwarding server should be bound to the
+             wildcard address.  The argument must be yes or no.  The default
+             is yes.
+
+     XAuthLocation
+             Specifies the full pathname of the xauth(1) program, or none to
+             not use one.  The default is /usr/X11R6/bin/xauth.
+
+TIME FORMATS
+     sshd(8) command-line arguments and configuration file options that
+     specify time may be expressed using a sequence of the form:
+     time[qualifier], where time is a positive integer value and qualifier is
+     one of the following:
+
+           M-bM-^_M-(noneM-bM-^_M-)  seconds
+           s | S   seconds
+           m | M   minutes
+           h | H   hours
+           d | D   days
+           w | W   weeks
+
+     Each member of the sequence is added together to calculate the total time
+     value.
+
+     Time format examples:
+
+           600     600 seconds (10 minutes)
+           10m     10 minutes
+           1h30m   1 hour 30 minutes (90 minutes)
+
+TOKENS
+     Arguments to some keywords can make use of tokens, which are expanded at
+     runtime:
+
+           %%    A literal M-bM-^@M-^X%M-bM-^@M-^Y.
+           %D    The routing domain in which the incoming connection was
+                 received.
+           %F    The fingerprint of the CA key.
+           %f    The fingerprint of the key or certificate.
+           %h    The home directory of the user.
+           %i    The key ID in the certificate.
+           %K    The base64-encoded CA key.
+           %k    The base64-encoded key or certificate for authentication.
+           %s    The serial number of the certificate.
+           %T    The type of the CA key.
+           %t    The key or certificate type.
+           %U    The numeric user ID of the target user.
+           %u    The username.
+
+     AuthorizedKeysCommand accepts the tokens %%, %f, %h, %k, %t, %U, and %u.
+
+     AuthorizedKeysFile accepts the tokens %%, %h, %U, and %u.
+
+     AuthorizedPrincipalsCommand accepts the tokens %%, %F, %f, %h, %i, %K,
+     %k, %s, %T, %t, %U, and %u.
+
+     AuthorizedPrincipalsFile accepts the tokens %%, %h, %U, and %u.
+
+     ChrootDirectory accepts the tokens %%, %h, %U, and %u.
+
+     RoutingDomain accepts the token %D.
+
+FILES
+     /etc/ssh/sshd_config
+             Contains configuration data for sshd(8).  This file should be
+             writable by root only, but it is recommended (though not
+             necessary) that it be world-readable.
