+\`configure' configures OpenSSH Portable to adapt to many kinds of systems.
+Usage: $0 [OPTION]... [VAR=VALUE]...
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+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

+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'.

+MODULI(5)                     File Formats Manual                    MODULI(5)
+NAME
+     moduli - 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

+SCP(1)                      General Commands Manual                     SCP(1)
+NAME
+     scp - secure copy (remote file copy program)
+SYNOPSIS
+     scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
+         [-l limit] [-o ssh_option] [-P port] [-S program]
+         [[user@]host1:]file1 ... [[user@]host2:]file2
+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.
+     File names may contain a user and host specification to indicate that the
+     file is to be copied to/from that host.  Local file names can be made
+     explicit using absolute or relative pathnames to avoid scp treating file
+     names containing `:' as host specifiers.  Copies between two remote hosts
+     are also permitted.
+     The options are as follows:
+     -1      Forces scp to use protocol 1.
+     -2      Forces scp to use protocol 2.
+     -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).

+             Name of program to use for the encrypted connection.  The program
+             must understand ssh(1) options.
+     -v      Verbose mode.  Causes scp and ssh(1) to print debugging messages
+             about their progress.  This is helpful in debugging connection,
+             authentication, and configuration problems.
+EXIT STATUS
+     The scp utility exits 0 on success, and >0 if an error occurs.

+SFTP-SERVER(8)              System Manager's Manual             SFTP-SERVER(8)
+NAME
+     sftp-server - 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 '%', %h 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 ``requests'', 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 - secure file transfer program
+SYNOPSIS
+     sftp [-1246aCfpqrv] [-B buffer_size] [-b batchfile] [-c cipher]
+          [-D sftp_server_path] [-F ssh_config] [-i identity_file] [-l limit]

+     sftp [user@]host[:file ...]
+     sftp [user@]host[:dir[/]]
+     sftp -b batchfile [user@]host
+DESCRIPTION
+     sftp is an interactive 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.  sftp connects and logs into the specified host, then enters
+     an interactive command mode.
+     The second usage format will retrieve files automatically if a non-
+     interactive authentication method is used; otherwise it will do so after
+     successful interactive authentication.
+     The third usage format allows sftp to start in a remote directory.
+     The final usage format allows for automated sessions using the -b option.
+     In such cases, it is necessary to configure non-interactive
+     authentication to obviate the need to enter a password at connection time
+     (see sshd(8) and ssh-keygen(1) for details).
+     Since some usage formats use colon characters to delimit host names from
+     path names, IPv6 addresses must be enclosed in square brackets to avoid
+     ambiguity.
+     The options are as follows:
+     -1      Specify the use of protocol version 1.
+     -2      Specify the use of protocol version 2.
+     -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.  A
+             batchfile of `-' 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 `-' 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

+     -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 for using sftp over protocol
+             version 1, or 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 (`\').
+     bye     Quit sftp.
+     cd path
+             Change remote directory to path.
+     chgrp grp path
+             Change group of file path to grp.  path may contain glob(3)
+             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(3) characters and may match multiple files.
+     chown own path
+             Change owner of file path to own.  path may contain glob(3)
+             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 ``statvfs@openssh.com'' 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(3)
+             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.
+     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(3) 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(3)
+             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 (`.').
+             -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(3)
+             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

+SSH-ADD(1)                  General Commands Manual                 SSH-ADD(1)
+NAME
+     ssh-add - adds private key identities to the authentication agent
+SYNOPSIS
+     ssh-add [-cDdkLlXx] [-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, ~/.ssh/id_ed25519 and
+     ~/.ssh/identity.  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 the SSH_ASKPASS program mentioned below.  Successful
+             confirmation is signaled by a zero exit status from the
+             SSH_ASKPASS program, 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 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.
+     -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 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.
+FILES
+     ~/.ssh/identity
+             Contains the protocol version 1 RSA authentication identity of
+             the user.
+     ~/.ssh/id_dsa
+             Contains the protocol version 2 DSA authentication identity of
+             the user.
+     ~/.ssh/id_ecdsa
+             Contains the protocol version 2 ECDSA authentication identity of
+             the user.
+     ~/.ssh/id_ed25519
+             Contains the protocol version 2 ED25519 authentication identity
+             of the user.
+     ~/.ssh/id_rsa
+             Contains the protocol version 2 RSA authentication identity of
+             the user.
+     Identity files should not be readable by anyone but the user.  Note that
+     ssh-add ignores identity files if they are accessible by others.
+EXIT STATUS
+     Exit status is 0 on success, 1 if the specified command fails, and 2 if
+     ssh-add is unable to contact the authentication agent.

+SSH-AGENT(1)                General Commands Manual               SSH-AGENT(1)
+NAME
+     ssh-agent - authentication agent
+SYNOPSIS
+     ssh-agent [-c | -s] [-d] [-a bind_address] [-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-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      Debug mode.  When this option is specified ssh-agent will not
+             fork.
+     -k      Kill the current agent (given by the SSH_AGENT_PID environment
+             variable).
+     -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 commandline 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 RSA keys for use by SSH protocol version 1
+     and DSA, ECDSA, ED25519 or RSA 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 for
+     use in SSH protocol 2 connections.
+     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/identity,
+     ~/.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 ``.pub'' 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 RSA1 keys, 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 ``user@host'' 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 (rsa1, 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.  This is used by /etc/rc to
+             generate new host keys.
+     -a rounds
+             When saving a new-format private key (i.e. an ed25519 key or any
+             SSH protocol 2 key when the -o flag is set), 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 768 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.  This operation is only supported for RSA1 keys.  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      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 ``RFC4716''.  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 ``RFC4716''.
+     -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 a certificate.
+     -l      Show fingerprint of specified public key file.  Private RSA1 keys
+             are also supported.  For RSA and DSA keys ssh-keygen tries to
+             find the matching public key file and prints its fingerprint.  If
+             combined with -v, an 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: ``RFC4716''
+             (RFC 4716/SSH2 public or private key), ``PKCS8'' (PEM PKCS8
+             public key) or ``PEM'' (PEM public key).  The default conversion
+             format is ``RFC4716''.
+     -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.  Please see the CERTIFICATES section
+             for details.  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.
+             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.
+             At present, no options are valid for host keys.
+     -o      Causes ssh-keygen to save SSH protocol 2 private keys using the
+             new OpenSSH format rather than the more compatible PEM format.
+             The new format has increased resistance to brute-force password
+             cracking but is not supported by versions of OpenSSH prior to
+             6.5.  Ed25519 keys always use the new private key 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 | rsa1
+             Specifies the type of key to create.  The possible values are
+             ``rsa1'' for protocol version 1 and ``dsa'', ``ecdsa'',
+             ``ed25519'', or ``rsa'' for protocol version 2.
+     -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 a
+             date in YYYYMMDD format, a time in YYYYMMDDHHMMSS format or a
+             relative time (to the current time) consisting of a minus sign
+             followed by a relative time in the format described in the TIME
+             FORMATS section of sshd_config(5).  The end time may be specified
+             as a YYYYMMDD date, a YYYYMMDDHHMMSS time or a relative time
+             starting with a plus character.
+             For example: ``+52w1d'' (valid from now to 52 weeks and one day
+             from now), ``-4w:+4w'' (valid from four weeks ago to four weeks
+             from now), ``20100101123000:20110101123000'' (valid from 12:30
+             PM, January 1st, 2010 to 12:30 PM, January 1st, 2011),
+             ``-1d:20110101'' (valid from yesterday to midnight, January 1st,
+             2011).
+     -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 host_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 user_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 its SHA1 hash.
+     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 commandline.  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.

+SSH-KEYSCAN(1)              General Commands Manual             SSH-KEYSCAN(1)
+NAME
+     ssh-keyscan - gather ssh public keys
+SYNOPSIS
+     ssh-keyscan [-46Hv] [-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.  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 ssh.  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      Forces ssh-keyscan to use IPv4 addresses only.
+     -6      Forces ssh-keyscan to use IPv6 addresses only.
+     -f file
+             Read hosts or ``addrlist namelist'' pairs from file, one per
+             line.  If - is supplied instead of a filename, ssh-keyscan will
+             read hosts or ``addrlist namelist'' pairs from the standard
+             input.
+     -H      Hash all hostnames and addresses in the output.  Hashed names may
+             be used normally by ssh and sshd, but they do not reveal
+             identifying information should the file's contents be disclosed.
+     -p port
+             Port to connect to 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, then the connection
+             is closed and the host in question considered unavailable.
+             Default is 5 seconds.
+     -t type
+             Specifies the type of the key to fetch from the scanned hosts.
+             The possible values are ``rsa1'' for protocol version 1 and
+             ``dsa'', ``ecdsa'', ``ed25519'', or ``rsa'' for protocol version
+             2.  Multiple values may be specified by separating them with
+             commas.  The default is to fetch ``rsa'', ``ecdsa'', and
+             ``ed25519'' keys.
+     -v      Verbose mode.  Causes ssh-keyscan to print debugging messages
+             about its progress.
+SECURITY
+     If an ssh_known_hosts file is constructed using ssh-keyscan without
+     verifying the keys, users will be vulnerable to man in the middle
+     attacks.  On the other hand, if the security model allows such a risk,
+     ssh-keyscan can help in the detection of tampered keyfiles or man in the
+     middle attacks which have begun after the ssh_known_hosts file was
+     created.
+FILES
+     Input 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

+     $ ssh-keyscan -t rsa,dsa,ecdsa,ed25519 -f ssh_hosts | \
+             sort -u - ssh_known_hosts | diff ssh_known_hosts -

+BUGS
+     It generates "Connection closed by remote host" messages on the consoles
+     of all the machines it scans if the server is older than version 2.9.
+     This is because it opens a connection to the ssh port, reads the public
+     key, and drops the connection as soon as it gets the key.

+SSH-KEYSIGN(8)              System Manager's Manual             SSH-KEYSIGN(8)
+NAME
+     ssh-keysign - 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 with SSH
+     protocol version 2.
+     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 ``yes''.
+     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.

+             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

+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 replace rlogin
+     and rsh, and 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 hostname (with optional user
+     name).  The user must prove his/her identity to the remote machine using
+     one of several methods depending on the protocol version used (see
+     below).
+     If command is specified, it is executed on the remote host instead of a
+     login shell.
+     The options are as follows:
+     -1      Forces ssh to try protocol version 1 only.
+     -2      Forces ssh to try protocol version 2 only.
+     -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_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), and the ``level'' can be controlled by the
+             CompressionLevel option for protocol version 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.
+             Protocol version 1 allows specification of a single cipher.  The
+             supported values are ``3des'', ``blowfish'', and ``des''.  For
+             protocol version 2, 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 ``dynamic'' 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 ``localhost'' indicates that the listening port
+             be bound for local use only, while an empty address or `*'
+             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: `~').
+             The escape character is only recognized at the beginning of a
+             line.  The escape character followed by a dot (`.') closes the
+             connection; followed by control-Z suspends the connection; and
+             followed by itself sends the escape character once.  Setting the
+             character to ``none'' 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
+             ``yes'', then a client started with -f will wait for all remote
+             port forwards to be successfully established before placing
+             itself in the background.
+     -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/identity for
+             protocol version 1, and ~/.ssh/id_dsa, ~/.ssh/id_ecdsa,
+             ~/.ssh/id_ed25519 and ~/.ssh/id_rsa for protocol version 2.
+             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).  ssh
+             will also try to load certificate information from the filename
+             obtained by appending -cert.pub to identity filenames.
+     -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
+             Specifies that the given port on the local (client) host is to be
+             forwarded to the given host and port on the remote side.  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 a connection is made to host port
+             hostport from the remote machine.  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
+             ``localhost'' indicates that the listening port be bound for
+             local use only, while an empty address or `*' 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 ``master'' mode for connection
+             sharing.  Multiple -M options places ssh into ``master'' mode
+             with confirmation required before slave connections are accepted.
+             Refer to the description of ControlMaster in ssh_config(5) for
+             details.
+     -m mac_spec
+             Additionally, for protocol version 2 a comma-separated list of
+             MAC (message authentication code) algorithms can be 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 (protocol version 2 only).
+     -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: ``check''
+             (check that the master process is running), ``forward'' (request
+             forwardings without command execution), ``cancel'' (cancel
+             forwardings), ``exit'' (request the master to exit), and ``stop''
+             (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 cipher | cipher-auth | mac | kex | key
+             Queries ssh for the algorithms supported for the specified
+             version 2.  The available features are: cipher (supported
+             symmetric ciphers), cipher-auth (supported symmetric ciphers that
+             support authenticated encryption), mac (supported message
+             integrity codes), kex (key exchange algorithms), key (key types).
+     -q      Quiet mode.  Causes most warning and diagnostic messages to be
+             suppressed.
+     -R [bind_address:]port:host:hostport
+             Specifies that the given port on the remote (server) host is to
+             be forwarded to the given host and port on the local side.  This
+             works by allocating a socket to listen to port on the remote
+             side, and whenever a connection is made to this port, the
+             connection is forwarded over the secure channel, and a connection
+             is made to host port hostport from the local machine.
+             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, the listening socket 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
+             `*', 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 `0', 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 ``none'' 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 are a feature of the SSH2 protocol which
+             facilitate the use of SSH as a secure transport for other
+             applications (eg. sftp(1)).  The subsystem is specified as the
+             remote command.
+     -T      Disable pseudo-tty allocation.
+     -t      Force pseudo-tty 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.  Works with
+             Protocol version 2 only.
+     -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
+             ``any'', which uses the next available tunnel device.  If
+             remote_tun is not specified, it defaults to ``any''.  See also
+             the Tunnel and TunnelDevice directives in ssh_config(5).  If the
+             Tunnel directive is unset, it is set to the default tunnel mode,
+             which is ``point-to-point''.
+     -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 protocols 1 and 2.  The default is to
+     use protocol 2 only, though this can be changed via the Protocol option
+     in ssh_config(5) or the -1 and -2 options (see above).  Both protocols
+     support similar authentication methods, but protocol 2 is the default
+     since it provides additional mechanisms for confidentiality (the traffic
+     is encrypted using AES, 3DES, Blowfish, CAST128, or Arcfour) and
+     integrity (hmac-md5, hmac-sha1, hmac-sha2-256, hmac-sha2-512, umac-64,
+     umac-128, hmac-ripemd160).  Protocol 1 lacks a strong mechanism for
+     ensuring the integrity of the connection.
+     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
+     protocol 2 has a configuration option to change the default order:
+     PreferredAuthentications.
+     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.  Protocol 1 is
+     restricted to using only RSA keys, but protocol 2 may use any.  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 user creates his/her key pair by running ssh-keygen(1).  This stores
+     the private key in ~/.ssh/identity (protocol 1), ~/.ssh/id_dsa (protocol
+     2 DSA), ~/.ssh/id_ecdsa (protocol 2 ECDSA), ~/.ssh/id_ed25519 (protocol 2
+     ED25519), or ~/.ssh/id_rsa (protocol 2 RSA) and stores the public key in
+     ~/.ssh/identity.pub (protocol 1), ~/.ssh/id_dsa.pub (protocol 2 DSA),
+     ~/.ssh/id_ecdsa.pub (protocol 2 ECDSA), ~/.ssh/id_ed25519.pub (protocol 2
+     ED25519), or ~/.ssh/id_rsa.pub (protocol 2 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) for more
+     information.
+     Challenge-response authentication works as follows: The server sends an
+     arbitrary "challenge" text, and prompts for a response.  Protocol 2
+     allows multiple challenges and responses; protocol 1 is restricted to
+     just one challenge/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, or logs into the machine and gives the
+     user a normal shell on the remote machine.  All communication with the
+     remote command or shell will be automatically encrypted.
+     If a pseudo-terminal has been allocated (normal login session), the user
+     may use the escape characters noted below.
+     If no pseudo-tty has been allocated, the session is transparent and can
+     be used to reliably transfer binary data.  On most systems, setting the
+     escape character to ``none'' 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 `~') 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 for SSH protocol
+             version 2 and 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 for SSH protocol
+             version 2 and 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
+     ``127.0.0.1'' (localhost) to remote server ``server.example.com'':
+         $ 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 ``server.example.com'', joining
+     channel ``#users'', nickname ``pinky'', 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 ``sleep 10'' 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 ``yes'' (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 ``proxy'' 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 ``yes'' (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.  Because of the difficulty of comparing host keys
+     just by looking at hex strings, there is also support to compare host
+     keys visually, using random art.  By setting the VisualHostKey option to
+     ``yes'', 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,
+     ``host.example.com''.  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 ``jane'' and
+     on tun device 2 from user ``john'', if PermitRootLogin is set to
+     ``forced-commands-only'':
+       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 ``hostname:n'', where
+                           ``hostname'' indicates the host where the shell
+                           runs, and `n' is an integer >= 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.
+     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
+     ``VARNAME=value'' 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/identity
+     ~/.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
+             3DES.
+     ~/.ssh/identity.pub
+     ~/.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.  If protocol version 1 is
+             used, ssh must be setuid root, since the host key is readable
+             only by root.  For protocol version 2, ssh uses ssh-keysign(8) to
+             access the host keys, eliminating the requirement that ssh be
+             setuid root when host-based authentication is used.  By default
+             ssh is not setuid root.
+     /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 - OpenSSH SSH client configuration files
+SYNOPSIS
+     ~/.ssh/config
+     /etc/ssh/ssh_config
+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 the
+     one given on the command line.
+     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 configuration file has the following format:
+     Empty lines and lines starting with `#' are comments.  Otherwise a line
+     is of the format ``keyword arguments''.  Configuration options may be
+     separated by whitespace or optional whitespace and exactly one `='; the
+     latter format is useful to avoid the need to quote whitespace when
+     specifying configuration options using the ssh, scp, and sftp -o option.
+     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):
+     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 `*'
+             as a pattern can be used to provide global defaults for all
+             hosts.  The host is the hostname argument given on the command
+             line (i.e. the name is not converted to a canonicalized host name
+             before matching).
+             A pattern entry may be negated by prefixing it with an
+             exclamation mark (`!').  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 keyword/criteria pairs or the single token all
+             which matches all criteria.  The available keywords are: exec,
+             host, originalhost, user, and localuser.
+             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.  The following character sequences in
+             the command will be expanded prior to execution: `%L' will be
+             substituted by the first component of the local host name, `%l'
+             will be substituted by the local host name (including any domain
+             name), `%h' will be substituted by the target host name, `%n'
+             will be substituted by the original target host name specified on
+             the command-line, `%p' the destination port, `%r' by the remote
+             login username, and `%u' by the username of the user running
+             ssh(1).
+             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 option.  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).
+     AddressFamily
+             Specifies which address family to use when connecting.  Valid
+             arguments are ``any'', ``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 is ``no''.
+     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.  Note that this option does not work if
+             UsePrivilegedPort is set to ``yes''.
+     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,
+             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 and canonicalisation results in the
+             target hostname changing, then the configuration files are
+             processed again using the new target name to pick up any new
+             configuration in matching Host 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.
+     ChallengeResponseAuthentication
+             Specifies whether to use challenge-response authentication.  The
+             argument to this keyword must be ``yes'' or ``no''.  The default
+             is ``yes''.
+     CheckHostIP
+             If this flag is set to ``yes'', ssh(1) will additionally check
+             the host IP address in the known_hosts file.  This allows ssh to
+             detect if a host key changed due to DNS spoofing.  If the option
+             is set to ``no'', the check will not be executed.  The default is
+             ``yes''.
+     Cipher  Specifies the cipher to use for encrypting the session in
+             protocol version 1.  Currently, ``blowfish'', ``3des'', and
+             ``des'' are supported.  des is only supported in the ssh(1)
+             client for interoperability with legacy protocol 1
+             implementations that do not support the 3des cipher.  Its use is
+             strongly discouraged due to cryptographic weaknesses.  The
+             default is ``3des''.
+     Ciphers
+             Specifies the ciphers allowed for protocol version 2 in order of
+             preference.  Multiple ciphers must be comma-separated.  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
+                   arcfour
+                   arcfour128
+                   arcfour256
+                   blowfish-cbc
+                   cast128-cbc
+                   chacha20-poly1305@openssh.com
+             The default is:
+                   aes128-ctr,aes192-ctr,aes256-ctr,
+                   aes128-gcm@openssh.com,aes256-gcm@openssh.com,
+                   chacha20-poly1305@openssh.com,
+                   arcfour256,arcfour128,
+                   aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,
+                   aes192-cbc,aes256-cbc,arcfour
+             The list of available ciphers may also be obtained using the -Q
+             option of ssh(1).
+     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 is
+             ``no''.
+     Compression
+             Specifies whether to use compression.  The argument must be
+             ``yes'' or ``no''.  The default is ``no''.
+     CompressionLevel
+             Specifies the compression level to use if compression is enabled.
+             The argument must be an integer from 1 (fast) to 9 (slow, best).
+             The default level is 6, which is good for most applications.  The
+             meaning of the values is the same as in gzip(1).  Note that this
+             option applies to protocol version 1 only.
+     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 to listen for control
+             connections, but require confirmation using the SSH_ASKPASS
+             program before they are accepted (see ssh-add(1) for details).
+             If the ControlPath cannot be opened, ssh 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.  In the path, `%L'
+             will be substituted by the first component of the local host
+             name, `%l' will be substituted by the local host name (including
+             any domain name), `%h' will be substituted by the target host
+             name, `%n' will be substituted by the original target host name
+             specified on the command line, `%p' the destination port, `%r' by
+             the remote login username, `%u' by the username of the user
+             running ssh(1), and `%C' by a hash of the concatenation:
+             %l%h%p%r.  It is recommended that any ControlPath used for
+             opportunistic connection sharing include at least %h, %p, and %r
+             (or alternatively %C).  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'', then the master connection will remain in the background
+             indefinitely (until killed or closed via a mechanism such as the
+             ssh(1) ``-O exit'' option).  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 `*' 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 is ``no''.  This option should
+             be placed in the non-hostspecific section.  See ssh-keysign(8)
+             for more information.
+     EscapeChar
+             Sets the escape character (default: `~').  The escape character
+             can also be set on the command line.  The argument should be a
+             single character, `^' 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.  The argument must be ``yes'' or ``no''.  The
+             default is ``no''.
+     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 is ``no''.
+             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 is ``no''.
+             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.
+             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'', 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.
+             The default is ``no''.
+             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 is ``no''.
+     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''.  Note that this option applies to protocol
+             version 2 only.
+     GSSAPIDelegateCredentials
+             Forward (delegate) credentials to the server.  The default is
+             ``no''.  Note that this option applies to protocol version 2
+             only.
+     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 is ``no''.  This option applies to protocol version 2
+             only and is similar to RhostsRSAAuthentication.
+     HostKeyAlgorithms
+             Specifies the protocol version 2 host key algorithms that the
+             client wants to use in order of preference.  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,
+                ssh-rsa-cert-v01@openssh.com,ssh-dss-cert-v01@openssh.com,
+                ssh-rsa-cert-v00@openssh.com,ssh-dss-cert-v00@openssh.com,
+                ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
+                ssh-ed25519,ssh-rsa,ssh-dss
+             If hostkeys are known for the destination host then this default
+             is modified to prefer their algorithms.
+     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.  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.  If the hostname
+             contains the character sequence `%h', then this will be replaced
+             with the host name specified on the command line (this is useful
+             for manipulating unqualified names).  The character sequence `%%'
+             will be replaced by a single `%' character, which may be used
+             when specifying IPv6 link-local addresses.
+             The default is the name given on the command line.  Numeric IP
+             addresses are also permitted (both on the command line and in
+             HostName specifications).
+     IdentitiesOnly
+             Specifies that ssh(1) should only use the authentication identity
+             files configured in the ssh_config files, even if ssh-agent(1) or
+             a PKCS11Provider offers more identities.  The argument to this
+             keyword must be ``yes'' or ``no''.  This option is intended for
+             situations where ssh-agent offers many different identities.  The
+             default is ``no''.
+     IdentityFile
+             Specifies a file from which the user's DSA, ECDSA, ED25519 or RSA
+             authentication identity is read.  The default is ~/.ssh/identity
+             for protocol version 1, and ~/.ssh/id_dsa, ~/.ssh/id_ecdsa,
+             ~/.ssh/id_ed25519 and ~/.ssh/id_rsa for protocol version 2.
+             Additionally, any identities represented by the authentication
+             agent will be used for authentication unless IdentitiesOnly is
+             set.  ssh(1) will try to load certificate information from the
+             filename obtained by appending -cert.pub to the path of a
+             specified IdentityFile.
+             The file name may use the tilde syntax to refer to a user's home
+             directory or one of the following escape characters: `%d' (local
+             user's home directory), `%u' (local user name), `%l' (local host
+             name), `%h' (remote host name) or `%r' (remote user name).
+             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.
+     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.
+     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'', or a numeric value.  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 ``lowdelay'' for interactive sessions and
+             ``throughput'' for non-interactive sessions.
+     KbdInteractiveAuthentication
+             Specifies whether to use keyboard-interactive authentication.
+             The argument to this keyword must be ``yes'' or ``no''.  The
+             default is ``yes''.
+     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'', ``pam'',
+             and ``skey''.
+     KexAlgorithms
+             Specifies the available KEX (Key Exchange) algorithms.  Multiple
+             algorithms must be comma-separated.  The default is:
+                   curve25519-sha256@libssh.org,
+                   ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,
+                   diffie-hellman-group-exchange-sha256,
+                   diffie-hellman-group14-sha1,
+                   diffie-hellman-group-exchange-sha1,
+                   diffie-hellman-group1-sha1
+     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.  The following escape character substitutions will be
+             performed: `%d' (local user's home directory), `%h' (remote host
+             name), `%l' (local host name), `%n' (host name as provided on the
+             command line), `%p' (remote port), `%r' (remote user name) or
+             `%u' (local user name) or `%C' by a hash of the concatenation:
+             %l%h%p%r.
+             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 `*' 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 in protocol
+             version 2 for data integrity protection.  Multiple algorithms
+             must be comma-separated.  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,
+                   umac-64@openssh.com,umac-128@openssh.com,
+                   hmac-sha2-256,hmac-sha2-512,
+                   hmac-md5-etm@openssh.com,hmac-sha1-etm@openssh.com,
+                   hmac-ripemd160-etm@openssh.com,
+                   hmac-sha1-96-etm@openssh.com,hmac-md5-96-etm@openssh.com,
+                   hmac-md5,hmac-sha1,hmac-ripemd160,
+                   hmac-sha1-96,hmac-md5-96
+     NoHostAuthenticationForLocalhost
+             This option can be used if the home directory is shared across
+             machines.  In this case localhost will refer to a different
+             machine on each of the machines and the user will get many
+             warnings about changed host keys.  However, this option disables
+             host authentication for localhost.  The argument to this keyword
+             must be ``yes'' or ``no''.  The default is to check the host key
+             for localhost.
+     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'' or ``no''.  The default is
+             ``yes''.
+     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 is ``no''.
+     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 protocol 2
+             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
+     Protocol
+             Specifies the protocol versions ssh(1) should support in order of
+             preference.  The possible values are `1' and `2'.  Multiple
+             versions must be comma-separated.  When this option is set to
+             ``2,1'' ssh will try version 2 and fall back to version 1 if
+             version 2 is not available.  The default is `2'.
+     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 `exec' directive to avoid a lingering
+             shell process.
+             In the command string, any occurrence of `%h' will be substituted
+             by the host name to connect, `%p' by the port, and `%r' by the
+             remote user name.  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
+     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''.
+     PubkeyAuthentication
+             Specifies whether to try public key authentication.  The argument
+             to this keyword must be ``yes'' or ``no''.  The default is
+             ``yes''.  This option applies to protocol version 2 only.
+     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 `K', `M', or `G' to indicate Kilobytes,
+             Megabytes, or Gigabytes, respectively.  The default is between
+             `1G' and `4G', 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.  This option applies to protocol version 2 only.
+     RemoteForward
+             Specifies that a TCP port on the remote machine be forwarded over
+             the secure channel to the specified host and port from the local
+             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.  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 `*' 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).
+     RhostsRSAAuthentication
+             Specifies whether to try rhosts based authentication with RSA
+             host authentication.  The argument must be ``yes'' or ``no''.
+             The default is ``no''.  This option applies to protocol version 1
+             only and requires ssh(1) to be setuid root.
+     RSAAuthentication
+             Specifies whether to try RSA authentication.  The argument to
+             this keyword must be ``yes'' or ``no''.  RSA authentication will
+             only be attempted if the identity file exists, or an
+             authentication agent is running.  The default is ``yes''.  Note
+             that this option applies to protocol version 1 only.
+     SendEnv
+             Specifies what variables from the local environ(7) should be sent
+             to the server.  Note that environment passing is only supported
+             for protocol 2.  The server must also support it, and the server
+             must be configured to accept these environment variables.  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.  The
+             default is not to send any environment variables.
+             See PATTERNS for more information on patterns.
+     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.  This option applies to protocol
+             version 2 only.
+     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.  This option applies to protocol version 2 only.
+     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 is ``no''.
+     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 trojan horse 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 ``no'', ssh will automatically add new host
+             keys to the user known hosts files.  If this flag is set to
+             ``ask'', 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.  The argument must be ``yes'',
+             ``no'', or ``ask''.  The default is ``ask''.
+     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''.
+     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''.  Specifying ``yes''
+             requests the default tunnel mode, which is ``point-to-point''.
+             The default is ``no''.
+     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''.
+     UsePrivilegedPort
+             Specifies whether to use a privileged port for outgoing
+             connections.  The argument must be ``yes'' or ``no''.  The
+             default is ``no''.  If set to ``yes'', ssh(1) must be setuid
+             root.  Note that this option must be set to ``yes'' for
+             RhostsRSAAuthentication with older servers.
+     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 argument must be ``yes'', ``no'', or ``ask''.  The
+             default is ``no''.  Note that this option applies to protocol
+             version 2 only.
+             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 hex
+             fingerprint string at login and for unknown host keys.  If this
+             flag is set to ``no'', no fingerprint strings are printed at
+             login and only the hex fingerprint string will be printed for
+             unknown host keys.  The default is ``no''.
+     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, `*' (a
+     wildcard that matches zero or more characters), or `?' (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
+     (`!').  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"
+FILES
+     ~/.ssh/config
+             This is the per-user configuration file.  The format of this file
+             is described above.  This file is used by the SSH client.
+             Because of the potential for abuse, this file must have strict

+     /etc/ssh/ssh_config
+             Systemwide configuration file.  This file provides defaults for

+NAME
+     sshd - OpenSSH SSH daemon
+SYNOPSIS
+     sshd [-46DdeiqTt] [-b bits] [-C connection_spec]
+          [-c host_certificate_file] [-E log_file] [-f config_file]
+          [-g login_grace_time] [-h host_key_file] [-k key_gen_time]
+          [-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.
+     -b bits
+             Specifies the number of bits in the ephemeral protocol version 1
+             server key (default 1024).
+     -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 to the specified user, host, and address
+             will be set before the configuration is written to standard
+             output.  The connection parameters are supplied as keyword=value
+             pairs.  The keywords are ``user'', ``host'', ``laddr'',
+             ``lport'', and ``addr''.  All are required and may be supplied in
+             any order, either with multiple -C options or as a comma-
+             separated list.
+     -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_key for protocol version 1, and
+             /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_ecdsa_key.
+             /etc/ssh/ssh_host_ed25519_key and /etc/ssh/ssh_host_rsa_key for
+             protocol version 2.  It is possible to have multiple host key
+             files for the different protocol versions and host key
+             algorithms.
+     -i      Specifies that sshd is being run from inetd(8).  sshd is normally
+             not run from inetd because it needs to generate the server key
+             before it can respond to the client, and this may take tens of
+             seconds.  Clients would have to wait too long if the key was
+             regenerated every time.  However, with small key sizes (e.g. 512)
+             using sshd from inetd may be feasible.
+     -k key_gen_time
+             Specifies how often the ephemeral protocol version 1 server key
+             is regenerated (default 3600 seconds, or one hour).  The
+             motivation for regenerating the key fairly often is that the key
+             is not stored anywhere, and after about an hour it becomes
+             impossible to recover the key for decrypting intercepted
+             communications even if the machine is cracked into or physically
+             seized.  A value of zero indicates that the key will never be
+             regenerated.
+     -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 RhostsRSAAuthentication,
+             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 protocols 1 and 2.  The default is to
+     use protocol 2 only, though this can be changed via the Protocol option
+     in sshd_config(5).  Protocol 2 supports DSA, ECDSA, ED25519 and RSA keys;
+     protocol 1 only supports RSA keys.  For both protocols, each host has a
+     host-specific key, normally 2048 bits, used to identify the host.
+     Forward security for protocol 1 is provided through an additional server
+     key, normally 768 bits, generated when the server starts.  This key is
+     normally regenerated every hour if it has been used, and is never stored
+     on disk.  Whenever a client connects, the daemon responds with its public
+     host and server keys.  The client compares the RSA host key against its
+     own database to verify that it has not changed.  The client then
+     generates a 256-bit random number.  It encrypts this random number using
+     both the host key and the server key, and sends the encrypted number to
+     the server.  Both sides then use this random number as a session key
+     which is used to encrypt all further communications in the session.  The
+     rest of the session is encrypted using a conventional cipher, currently
+     Blowfish or 3DES, with 3DES being used by default.  The client selects
+     the encryption algorithm to use from those offered by the server.
+     For protocol 2, 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-ripemd160, 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 dependant. Some platforms have
+     their own account database (eg AIX) and some modify the passwd field (
+     `*LK*' on Solaris and UnixWare, `*' on HP-UX, containing `Nologin' on
+     Tru64, a leading `*LOCKED*' on FreeBSD and a leading `!' 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 `NP' or `*NP*' ).
+     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 ``rc'' files are given the X11
+                authentication protocol and cookie in standard input.  See
+                SSHRC, below.
+           9.   Runs user's shell or command.
+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 none is 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 `#' are
+     ignored as comments).  Protocol 1 public keys consist of the following
+     space-separated fields: options, bits, exponent, modulus, comment.
+     Protocol 2 public key consist of: options, keytype, base64-encoded key,
+     comment.  The options field is optional; its presence is determined by
+     whether the line starts with a number or not (the options field never
+     starts with a number).  The bits, exponent, modulus, and comment fields
+     give the RSA key for protocol version 1; the comment field is not used
+     for anything (but may be convenient for the user to identify the key).
+     For protocol version 2 the keytype is ``ecdsa-sha2-nistp256'',
+     ``ecdsa-sha2-nistp384'', ``ecdsa-sha2-nistp521'', ``ssh-ed25519'',
+     ``ssh-dss'' or ``ssh-rsa''.
+     Note that lines in this file are usually 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
+     identity.pub, 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 for protocol 1 and protocol
+     2 keys of 768 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):
+     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.  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 either a sshd_config(5) ForceCommand directive
+             or a command embedded in a certificate.
+     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.
+             This option is automatically disabled if UseLogin is enabled.
+     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.
+     permitopen="host:port"
+             Limit local ``ssh -L'' port forwarding 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.
+     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.
+     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.
+     An example authorized_keys file:
+        # Comments allowed at start of line
+        ssh-rsa AAAAB3Nza...LiPk== user@example.net

+        jane@example.net
+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 from an unknown host, its key
+     is added to the per-user file.
+     Each line in these files contains the following fields: markers
+     (optional), hostnames, bits, exponent, modulus, comment.  The fields are
+     separated by spaces.
+     The marker is optional, but if it is present then it must be one of
+     ``@cert-authority'', to indicate that the line contains a certification
+     authority (CA) key, or ``@revoked'', 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 (`*' and `?' act as
+     wildcards); each pattern in turn is matched against the canonical host
+     name (when authenticating a client) or against the user-supplied name
+     (when authenticating a server).  A pattern may also be preceded by `!' 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 `[' and `]'
+     brackets then followed by `:' 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 `|' character.  Only one hashed hostname may
+     appear on a single line and none of the above negation or wildcard
+     operators may be applied.
+     Bits, exponent, and modulus are taken directly from the RSA host key;
+     they can be obtained, for example, from /etc/ssh/ssh_host_key.pub.  The
+     optional comment field continues to the end of the line, and is not used.
+     Lines starting with `#' 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 ``@cert-authority''
+     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 ``@revoked'' 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
+     /etc/ssh/ssh_host_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

+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
+             ``no''.
+     ~/.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
+             `#'), 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".  The file format is described in moduli(5).
+     /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_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.  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_key.pub
+     /etc/ssh/ssh_host_dsa_key.pub
+     /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 - OpenSSH SSH daemon configuration file
+SYNOPSIS
+     /etc/ssh/sshd_config
+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.  Lines starting with `#' 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 in
+             ssh_config(5) for how to configure the client.  Note that
+             environment passing is only supported for protocol 2.  Variables
+             are specified by name, which may contain the wildcard characters
+             `*' and `?'.  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'', ``inet'' (use IPv4 only), or ``inet6''
+             (use IPv6 only).  The default is ``any''.
+     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.
+     AllowTcpForwarding
+             Specifies whether TCP forwarding is permitted.  The available
+             options are ``yes'' 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.  The default is ``yes''.  Note that
+             disabling TCP forwarding does not improve security unless users
+             are also denied shell access, as they can always install their
+             own forwarders.
+     AllowStreamLocalForwarding
+             Specifies whether StreamLocal (Unix-domain socket) forwarding is
+             permitted.  The available options are ``yes'' 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.  The default is ``yes''.  Note that disabling StreamLocal
+             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.  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 comma-separated lists of authentication
+             method names.  Successful authentication requires completion of
+             every method in at least one of these lists.
+             For example, an argument of ``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'', ``pam'', or
+             ``skey'', depending on the server configuration.  For example,
+             ``keyboard-interactive:bsdauth'' would restrict keyboard
+             interactive authentication to the ``bsdauth'' device.
+             This option is only available for SSH protocol 2 and will yield a
+             fatal error if enabled if protocol 1 is also enabled.  Note that
+             each authentication method listed should also be explicitly
+             enabled in the configuration.  The default is not to require
+             multiple authentication; successful completion of a single
+             authentication method is sufficient.
+     AuthorizedKeysCommand
+             Specifies a program to be used to look up the user's public keys.
+             The program must be owned by root and not writable by group or
+             others.  It will be invoked with a single argument of the
+             username being authenticated, and 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.
+     AuthorizedKeysFile
+             Specifies the file that contains the public keys that can be used
+             for user authentication.  The format is described in the
+             AUTHORIZED_KEYS FILE FORMAT section of sshd(8).
+             AuthorizedKeysFile may contain tokens of the form %T which are
+             substituted during connection setup.  The following tokens are
+             defined: %% is replaced by a literal '%', %h is replaced by the
+             home directory of the user being authenticated, and %u is
+             replaced by the username of that user.  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.  The default is
+             ``.ssh/authorized_keys .ssh/authorized_keys2''.
+     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 `#' are ignored.
+             AuthorizedPrincipalsFile may contain tokens of the form %T which
+             are substituted during connection setup.  The following tokens
+             are defined: %% is replaced by a literal '%', %h is replaced by
+             the home directory of the user being authenticated, and %u is
+             replaced by the username of that user.  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 - 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.  This option is only available for
+             protocol version 2.  By default, no banner is displayed.
+     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.  All components of the pathname must be root-
+             owned directories that are not writable by any other user or
+             group.  After the chroot, sshd(8) changes the working directory
+             to the user's home directory.
+             The pathname may contain the following tokens that are expanded
+             at runtime once the connecting user has been authenticated: %% is
+             replaced by a literal '%', %h is replaced by the home directory
+             of the user being authenticated, and %u is replaced by the
+             username of that user.
+             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), arandom(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).
+             The default is not to chroot(2).
+     Ciphers
+             Specifies the ciphers allowed for protocol version 2.  Multiple
+             ciphers must be comma-separated.  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
+                   arcfour
+                   arcfour128
+                   arcfour256
+                   blowfish-cbc
+                   cast128-cbc
+                   chacha20-poly1305@openssh.com
+             The default is:
+                   aes128-ctr,aes192-ctr,aes256-ctr,
+                   aes128-gcm@openssh.com,aes256-gcm@openssh.com,
+                   chacha20-poly1305@openssh.com
+             The list of available ciphers may also be obtained using the -Q
+             option of ssh(1).
+     ClientAliveCountMax
+             Sets the number of client alive messages (see below) 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 (below).  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 (see below) is
+             set to 15, and ClientAliveCountMax is left at the default,
+             unresponsive SSH clients will be disconnected after approximately
+             45 seconds.  This option applies to protocol version 2 only.
+     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.  This option applies to protocol
+             version 2 only.
+     Compression
+             Specifies whether compression is allowed, or delayed until the
+             user has authenticated successfully.  The argument must be
+             ``yes'', ``delayed'', or ``no''.  The default is ``delayed''.
+     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.  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.
+     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.
+     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''.  Note that this option applies to protocol
+             version 2 only.
+     GSSAPICleanupCredentials
+             Specifies whether to automatically destroy the user's credentials
+             cache on logout.  The default is ``yes''.  Note that this option
+             applies to protocol version 2 only.
+     HostbasedAuthentication
+             Specifies whether rhosts or /etc/hosts.equiv authentication
+             together with successful public key client host authentication is
+             allowed (host-based authentication).  This option is similar to
+             RhostsRSAAuthentication and applies to protocol version 2 only.
+             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
+             default is /etc/ssh/ssh_host_key for protocol version 1, and
+             /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_ecdsa_key,
+             /etc/ssh/ssh_host_ed25519_key and /etc/ssh/ssh_host_rsa_key for
+             protocol version 2.  Note that sshd(8) will refuse to use a file
+             if it is group/world-accessible.  It is possible to have multiple
+             host key files.  ``rsa1'' keys are used for version 1 and
+             ``dsa'', ``ecdsa'', ``ed25519'' or ``rsa'' are used for version 2
+             of the SSH protocol.  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
+             ``SSH_AUTH_SOCK'' is specified, the location of the socket will
+             be read from the SSH_AUTH_SOCK environment variable.
+     IgnoreRhosts
+             Specifies that .rhosts and .shosts files will not be used in
+             RhostsRSAAuthentication or 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 RhostsRSAAuthentication or
+             HostbasedAuthentication.  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'', or a numeric value.  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 ``lowdelay'' for
+             interactive sessions and ``throughput'' 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.  The supported algorithms
+             are:
+                   curve25519-sha256@libssh.org
+                   diffie-hellman-group1-sha1
+                   diffie-hellman-group14-sha1
+                   diffie-hellman-group-exchange-sha1
+                   diffie-hellman-group-exchange-sha256
+                   ecdh-sha2-nistp256
+                   ecdh-sha2-nistp384
+                   ecdh-sha2-nistp521
+             The default is:
+                   curve25519-sha256@libssh.org,
+                   ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,
+                   diffie-hellman-group-exchange-sha256,
+                   diffie-hellman-group14-sha1
+     KeyRegenerationInterval
+             In protocol version 1, the ephemeral server key is automatically
+             regenerated after this many seconds (if it has been used).  The
+             purpose of regeneration is to prevent decrypting captured
+             sessions by later breaking into the machine and stealing the
+             keys.  The key is never stored anywhere.  If the value is 0, the
+             key is never regenerated.  The default is 3600 (seconds).
+     ListenAddress
+             Specifies the local addresses sshd(8) should listen on.  The
+             following forms may be used:
+                   ListenAddress host|IPv4_addr|IPv6_addr
+                   ListenAddress host|IPv4_addr:port
+                   ListenAddress [host|IPv6_addr]:port
+             If port is not specified, sshd will listen on the address and all
+             prior Port options specified.  The default is to listen on all
+             local addresses.  Multiple ListenAddress options are permitted.
+             Additionally, any Port options must precede this option for non-
+             port qualified addresses.
+     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 in protocol version 2 for
+             data integrity protection.  Multiple algorithms must be comma-
+             separated.  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-ripemd160
+                   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-ripemd160-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,
+                   umac-64@openssh.com,umac-128@openssh.com,
+                   hmac-sha2-256,hmac-sha2-512
+     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 satisified,
+             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, and
+             Address.  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, e.g.
+             ``192.0.2.0/24'' or ``3ffe:ffff::/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, AllowTcpForwarding,
+             AllowUsers, AuthenticationMethods, AuthorizedKeysCommand,
+             AuthorizedKeysCommandUser, AuthorizedKeysFile,
+             AuthorizedPrincipalsFile, Banner, ChrootDirectory, DenyGroups,
+             DenyUsers, ForceCommand, GatewayPorts, GSSAPIAuthentication,
+             HostbasedAuthentication, HostbasedUsesNameFromPacketOnly,
+             KbdInteractiveAuthentication, KerberosAuthentication,
+             MaxAuthTries, MaxSessions, PasswordAuthentication,
+             PermitEmptyPasswords, PermitOpen, PermitRootLogin, PermitTTY,
+             PermitTunnel, PermitUserRC, PubkeyAuthentication, RekeyLimit,
+             RhostsRSAAuthentication, RSAAuthentication, 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 sessions permitted per
+             network connection.  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''.
+     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.  By
+             default all port forwarding requests are permitted.
+     PermitRootLogin
+             Specifies whether root can log in using ssh(1).  The argument
+             must be ``yes'', ``without-password'', ``forced-commands-only'',
+             or ``no''.  The default is ``yes''.
+             If this option is set to ``without-password'', password
+             authentication is 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.
+     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''.
+     PermitTTY
+             Specifies whether pty(4) allocation is permitted.  The default is
+             ``yes''.
+     PermitUserEnvironment
+             Specifies whether ~/.ssh/environment and environment= options in
+             ~/.ssh/authorized_keys are processed by sshd(8).  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.  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''.
+     Protocol
+             Specifies the protocol versions sshd(8) supports.  The possible
+             values are `1' and `2'.  Multiple versions must be comma-
+             separated.  The default is `2'.  Note that the order of the
+             protocol list does not indicate preference, because the client
+             selects among multiple protocol versions offered by the server.
+             Specifying ``2,1'' is identical to ``1,2''.
+     PubkeyAuthentication
+             Specifies whether public key authentication is allowed.  The
+             default is ``yes''.  Note that this option applies to protocol
+             version 2 only.
+     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 `K', `M', or `G' to indicate Kilobytes,
+             Megabytes, or Gigabytes, respectively.  The default is between
+             `1G' and `4G', 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.  This option
+             applies to protocol version 2 only.
+     RevokedKeys
+             Specifies revoked public keys.  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).
+     RhostsRSAAuthentication
+             Specifies whether rhosts or /etc/hosts.equiv authentication
+             together with successful RSA host authentication is allowed.  The
+             default is ``no''.  This option applies to protocol version 1
+             only.
+     RSAAuthentication
+             Specifies whether pure RSA authentication is allowed.  The
+             default is ``yes''.  This option applies to protocol version 1
+             only.
+     ServerKeyBits
+             Defines the number of bits in the ephemeral protocol version 1
+             server key.  The minimum value is 512, and the default is 1024.
+     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(8) 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.  Note that this option
+             applies to protocol version 2 only.
+     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.  Keys are listed one per line; empty lines and
+             comments starting with `#' 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
+             check that the resolved host name for the remote IP address maps
+             back to the very same IP address.  The default is ``yes''.
+     UseLogin
+             Specifies whether login(1) is used for interactive login
+             sessions.  The default is ``no''.  Note that login(1) is never
+             used for remote command execution.  Note also, that if this is
+             enabled, X11Forwarding will be disabled because login(1) does not
+             know how to handle xauth(1) cookies.  If UsePrivilegeSeparation
+             is specified, it will be disabled after authentication.
+     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''.
+     UsePrivilegeSeparation
+             Specifies whether sshd(8) separates privileges by creating an
+             unprivileged child process to deal with incoming network traffic.
+             After successful authentication, another process will be created
+             that has the privilege of the authenticated user.  The goal of
+             privilege separation is to prevent privilege escalation by
+             containing any corruption within the unprivileged processes.  The
+             default is ``yes''.  If UsePrivilegeSeparation is set to
+             ``sandbox'' then the pre-authentication unprivileged process is
+             subject to additional restrictions.
+     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 below), 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.  X11 forwarding is automatically disabled if UseLogin
+             is enabled.
+     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.  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:
+           <none>  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)
+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.
