+openssh (1:7.6p1-1) unstable; urgency=medium
+
+  OpenSSH 7.6 includes a number of changes that may affect existing
+  configurations:
+
+   * ssh(1): Delete SSH protocol version 1 support, associated configuration
+     options and documentation.
+   * ssh(1)/sshd(8): Remove support for the hmac-ripemd160 MAC.
+   * ssh(1)/sshd(8): Remove support for the arcfour, blowfish and CAST
+     ciphers.
+   * Refuse RSA keys <1024 bits in length and improve reporting for keys
+     that do not meet this requirement.
+   * ssh(1): Do not offer CBC ciphers by default.

+openssh (1:7.5p1-1) experimental; urgency=medium
+
+  OpenSSH 7.5 includes a number of changes that may affect existing
+  configurations:
+
+   * This release deprecates the sshd_config UsePrivilegeSeparation option,
+     thereby making privilege separation mandatory.
+
+   * The format of several log messages emitted by the packet code has
+     changed to include additional information about the user and their
+     authentication state. Software that monitors ssh/sshd logs may need to
+     account for these changes. For example:
+
+       Connection closed by user x 1.1.1.1 port 1234 [preauth]
+       Connection closed by authenticating user x 10.1.1.1 port 1234 [preauth]
+       Connection closed by invalid user x 1.1.1.1 port 1234 [preauth]
+
+     Affected messages include connection closure, timeout, remote
+     disconnection, negotiation failure and some other fatal messages
+     generated by the packet code.

+
+  This version restores the default for AuthorizedKeysFile to search both
+  ~/.ssh/authorized_keys and ~/.ssh/authorized_keys2, as was the case in
+  Debian configurations before 1:7.4p1-1.  Upstream intends to phase out
+  searching ~/.ssh/authorized_keys2 by default, so you should ensure that
+  you are only using ~/.ssh/authorized_keys, at least for critical
+  administrative access; do not assume that the current default will remain
+  in place forever.

+
+openssh (1:7.4p1-1) unstable; urgency=medium
+
+  OpenSSH 7.4 includes a number of changes that may affect existing
+  configurations:
+
+   * ssh(1): Remove 3des-cbc from the client's default proposal.  64-bit
+     block ciphers are not safe in 2016 and we don't want to wait until
+     attacks like SWEET32 are extended to SSH.  As 3des-cbc was the only
+     mandatory cipher in the SSH RFCs, this may cause problems connecting to
+     older devices using the default configuration, but it's highly likely
+     that such devices already need explicit configuration for key exchange
+     and hostkey algorithms already anyway.
+   * sshd(8): Remove support for pre-authentication compression.  Doing
+     compression early in the protocol probably seemed reasonable in the
+     1990s, but today it's clearly a bad idea in terms of both cryptography
+     (cf. multiple compression oracle attacks in TLS) and attack surface.
+     Pre-auth compression support has been disabled by default for >10
+     years.  Support remains in the client.
+   * ssh-agent will refuse to load PKCS#11 modules outside a whitelist of
+     trusted paths by default.  The path whitelist may be specified at
+     run-time.
+   * sshd(8): When a forced-command appears in both a certificate and an
+     authorized keys/principals command= restriction, sshd will now refuse
+     to accept the certificate unless they are identical.  The previous
+     (documented) behaviour of having the certificate forced-command
+     override the other could be a bit confusing and error-prone.
+   * sshd(8): Remove the UseLogin configuration directive and support for
+     having /bin/login manage login sessions.
+
+  The unprivileged sshd process that deals with pre-authentication network
+  traffic is now subject to additional sandboxing restrictions by default:
+  that is, the default sshd_config now sets UsePrivilegeSeparation to
+  "sandbox" rather than "yes".  This has been the case upstream for a while,
+  but until now the Debian configuration diverged unnecessarily.

+openssh (1:7.2p1-1) unstable; urgency=medium
+
+  OpenSSH 7.2 disables a number of legacy cryptographic algorithms by
+  default in ssh:
+
+   * Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and the
+     rijndael-cbc aliases for AES.
+   * MD5-based and truncated HMAC algorithms.
+
+  These algorithms are already disabled by default in sshd.

+
+openssh (1:7.1p1-2) unstable; urgency=medium
+
+  OpenSSH 7.0 disables several pieces of weak, legacy, and/or unsafe
+  cryptography.
+
+   * Support for the legacy SSH version 1 protocol is disabled by default at
+     compile time.  Note that this also means that the Cipher keyword in
+     ssh_config(5) is effectively no longer usable; use Ciphers instead for
+     protocol 2.  The openssh-client-ssh1 package includes "ssh1", "scp1",
+     and "ssh-keygen1" binaries which you can use if you have no alternative
+     way to connect to an outdated SSH1-only server; please contact the
+     server administrator or system vendor in such cases and ask them to
+     upgrade.
+   * Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is
+     disabled by default at run-time.  It may be re-enabled using the
+     instructions at http://www.openssh.com/legacy.html
+   * Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by
+     default at run-time.  These may be re-enabled using the instructions at
+     http://www.openssh.com/legacy.html
+   * Support for the legacy v00 cert format has been removed.
+
+  Future releases will retire more legacy cryptography, including:
+
+   * Refusing all RSA keys smaller than 1024 bits (the current minimum is
+     768 bits).
+   * Several ciphers will be disabled by default: blowfish-cbc, cast128-cbc,
+     all arcfour variants, and the rijndael-cbc aliases for AES.
+   * MD5-based HMAC algorithms will be disabled by default.

+openssh (1:6.7p1-5) unstable; urgency=medium
+
+  openssh-server 1:6.7p1-4 changed the default setting of AcceptEnv to list
+  a number of specific LC_FOO variables rather than the wildcard LC_*.  I
+  have since been persuaded that this was a bad idea and have reverted it,
+  but it is difficult to automatically undo the change to
+  /etc/ssh/sshd_config without compounding the problem (that of modifying
+  configuration that some users did not want to be modified) further.  Most
+  users who upgraded via version 1:6.7p1-4 should restore the previous value
+  of "AcceptEnv LANG LC_*" in /etc/ssh/sshd_config.

+  previously using an unofficial build of Debian's OpenSSH package with
+  OpenSC-based smartcard support added, then note that commands like

+  /usr/lib/opensc-pkcs11.so' instead.

+
+  The ssh package has been split into openssh-client and openssh-server. If
+  you had previously requested that the sshd server should not be run, then
+  that request will still be honoured. However, the recommended approach is
+  now to remove the openssh-server package if you do not want to run sshd.
+  You can remove the old /etc/ssh/sshd_not_to_be_run marker file after doing
+  that.

+openssh (1:3.5p1-1) unstable; urgency=low
+
+  This version of OpenSSH disables the environment option for public keys by
+  default, in order to avoid certain attacks (for example, LD_PRELOAD). If
+  you are using this option in an authorized_keys file, beware that the keys
+  in question will no longer work until the option is removed.
+
+  To re-enable this option, set "PermitUserEnvironment yes" in
+  /etc/ssh/sshd_config after the upgrade is complete, taking note of the
+  warning in the sshd_config(5) manual page.

+OpenSSH for Debian
+------------------
+
+UPGRADE ISSUES
+==============
+
+PermitRootLogin
+---------------
+
+As of 1:6.6p1-1, new installations will be set to "PermitRootLogin
+without-password" (or the synonymous "PermitRootLogin prohibit-password" as
+of 1:7.1p1-1).  This disables password authentication for root, foiling
+password dictionary attacks on the root user.  Some sites may wish to use
+the stronger "PermitRootLogin forced-commands-only" or "PermitRootLogin no",
+but note that "PermitRootLogin no" will break setups that SSH to root with a
+forced command to take full-system backups.  You can use PermitRootLogin in
+a Match block if you want finer-grained control here.
+
+For many years Debian's OpenSSH packaging used "PermitRootLogin yes", in
+line with upstream.  To avoid breaking local setups, this is still true for
+installations upgraded from before 1:6.6p1-1.  If you wish to change this,
+you should edit /etc/ssh/sshd_config, change it manually, and run "service
+ssh restart" as root.
+
+Disabling PermitRootLogin means that an attacker possessing credentials for
+the root account (any credentials in the case of "yes", or private key
+material in the case of "prohibit-password") must compromise a normal user
+account rather than being able to SSH directly to root.  Be careful to avoid
+a false illusion of security if you change this setting; any account you
+escalate to root from should be considered equivalent to root for the
+purposes of security against external attack.  You might for example disable
+it if you know you will only ever log in as root from the physical console.
+
+Since the root account does not generally have non-password credentials
+unless you explicitly install an SSH public key in its
+~/.ssh/authorized_keys, which you presumably only do if you want to SSH to
+it, "prohibit-password" should be a reasonable default for most sites.
+
+As of OpenSSH 7.0, this is the upstream default.
+
+For further discussion, see:
+
+  https://bugs.debian.org/298138
+  https://bugzilla.mindrot.org/show_bug.cgi?id=2164
+
+X11 Forwarding
+--------------
+
+ssh's default for ForwardX11 has been changed to ``no'' because it has
+been pointed out that logging into remote systems administered by
+untrusted people is likely to open you up to X11 attacks, so you
+should have to actively decide that you trust the remote machine's
+root, before enabling X11.  I strongly recommend that you do this on a
+machine-by-machine basis, rather than just enabling it in the default
+host settings.
+
+In order for X11 forwarding to work, you need to install xauth on the
+server. In Debian this is in the xbase-clients package.
+
+As of OpenSSH 3.1, the remote $DISPLAY uses localhost by default to reduce
+the security risks of X11 forwarding. Look up X11UseLocalhost in
+sshd_config(8) if this is a problem.
+
+OpenSSH 3.8 invented ForwardX11Trusted, which when set to no causes the
+ssh client to create an untrusted X cookie so that attacks on the
+forwarded X11 connection can't become attacks on X clients on the remote
+machine. However, this has some problems in implementation - notably a
+very short timeout of the untrusted cookie - breaks large numbers of
+existing setups, and generally seems immature. The Debian package
+therefore sets the default for this option to "yes" (in ssh itself,
+rather than in ssh_config).
+
+Fallback to RSH
+---------------
+
+The default for this setting has been changed from Yes to No, for
+security reasons, and to stop the delay attempting to rsh to machines
+that don't offer the service.  Simply switch it back on in either
+/etc/ssh/ssh_config or ~/.ssh/config for those machines that you need
+it for.
+
+Setgid ssh-agent and environment variables
+------------------------------------------
+
+As of version 1:3.5p1-1, ssh-agent is installed setgid to prevent ptrace()
+attacks retrieving private key material. This has the side-effect of causing
+glibc to remove certain environment variables which might have security
+implications for set-id programs, including LD_PRELOAD, LD_LIBRARY_PATH, and
+TMPDIR.
+
+If you need to set any of these environment variables, you will need to do
+so in the program exec()ed by ssh-agent. This may involve creating a small
+wrapper script.
+
+Symlink Hostname invocation
+---------------------------
+
+This version of ssh no longer includes support for invoking ssh with the
+hostname as the name of the file run.  People wanting this support should
+use the ssh-argv0 script.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+OTHER ISSUES
+============
+
+Authorization Forwarding
+------------------------
+
+Similarly, root on a remote server could make use of your ssh-agent
+(while you're logged into their machine) to obtain access to machines
+which trust your keys.  This feature is therefore disabled by default.
+You should only re-enable it for those hosts (in your ~/.ssh/config or
+/etc/ssh/ssh_config) where you are confident that the remote machine
+is not a threat.
+
+Problems logging in with RSA authentication
+-------------------------------------------
+
+If you have trouble logging in with RSA authentication then the
+problem is probably caused by the fact that you have your home
+directory writable by group, as well as user (this is the default on
+Debian systems).
+
+Depending upon other settings on your system (i.e. other users being
+in your group) this could open a security hole, so you will need to
+make your home directory writable only by yourself.  Run this command,
+as yourself:
+
+  chmod g-w ~/
+
+to remove group write permissions.  If you use ssh-copy-id to install your
+keys, it does this for you.
+
+-L option of ssh nonfree
+------------------------
+
+non-free ssh supported the usage of the option -L to use a non privileged
+port for scp. This option will not be supported by scp from openssh.
+
+Please use instead scp -o "UsePrivilegedPort=no" as documented in the
+manpage to scp itself.
+
+Problem logging in because of TCP-Wrappers
+------------------------------------------
+
+ssh is compiled with support for tcp-wrappers. So if you can no longer
+log into your system, please check that /etc/hosts.allow and /etc/hosts.deny
+are configured so that ssh is not blocked.
+
+Kerberos support
+----------------
+
+ssh is now compiled with Kerberos support. Unfortunately, privilege
+separation is incompatible with parts of Kerberos support for protocol 2;
+you may need to run kinit after logging in.
+
+Interoperability between scp and the ssh.com SSH server
+-------------------------------------------------------
+
+In version 2 and greater of the commercial SSH server produced by SSH
+Communications Security, scp was changed to use SFTP (SSH2's file transfer
+protocol) instead of the traditional rcp-over-ssh, thereby breaking
+compatibility. The OpenSSH developers regard this as a bug in the ssh.com
+server, and do not currently intend to change OpenSSH's scp to match.
+
+Workarounds for this problem are to install scp1 on the server (scp2 will
+fall back to it), to use sftp, or to use some other transfer mechanism such
+as rsync-over-ssh or tar-over-ssh.
+
+Running sshd from inittab
+-------------------------
+
+Some people find it useful to run the sshd server from inittab, to make sure
+that it always stays running. To do this, stop sshd ('service ssh stop'),
+add the following line to /etc/inittab, and run 'telinit q':
+
+  ss:2345:respawn:/usr/sbin/sshd -D
+
+If you do this, note that you will need to stop sshd being started in the
+normal way ('update-rc.d ssh disable') and that you will need to restart
+this sshd manually on upgrades.
+
+Per-connection sshd instances with systemd
+------------------------------------------
+
+If you want to reconfigure systemd to listen on port 22 itself and launch an
+instance of sshd for each connection (inetd-style socket activation), then
+you can run:
+
+  systemctl stop ssh.service
+  systemctl start ssh.socket
+
+To make this permanent:
+
+  systemctl disable ssh.service
+  systemctl enable ssh.socket
+
+This may be appropriate in environments where minimal footprint is critical
+(e.g. cloud guests).  Be aware that this bypasses MaxStartups, and systemd's
+MaxConnections cannot quite replace this as it cannot distinguish between
+authenticated and unauthenticated connections; see
+https://bugzilla.redhat.com/show_bug.cgi?id=963268 for more discussion.
+
+The provided ssh.socket unit file sets ListenStream=22.  If you need to have
+it listen on a different address or port, then you will need to do this as
+follows (modifying ListenStream to match your requirements):
+
+  mkdir -p /etc/systemd/system/ssh.socket.d
+  cat >/etc/systemd/system/ssh.socket.d/listen.conf <<EOF
+  [Socket]
+  ListenStream=2222
+  EOF
+  systemctl daemon-reload
+
+See systemd.socket(5) for details.
+
+Terminating SSH sessions cleanly on shutdown/reboot with systemd
+----------------------------------------------------------------
+
+If you have libpam-systemd >= 230 installed (following openssh-server's
+Recommends) and "UsePAM yes" in sshd_config (the default configuration
+shipped by this package), then SSH sessions will be terminated cleanly when
+the server is shut down or rebooted.
+
+If either of these conditions does not hold, then you may find that SSH
+sessions hang silently when the server is shut down or rebooted.  If you do
+not want to use PAM or configure it properly for whatever reason, then you
+can instead copy
+/usr/share/doc/openssh-server/examples/ssh-session-cleanup.service to
+/etc/systemd/system/ and run "systemctl enable ssh-session-cleanup.service".
+
+Non-systemd users may find /usr/lib/openssh/ssh-session-cleanup helpful if
+they have a similar problem, although at present there is no system
+integration for this for anything other than systemd.
+
+SSH protocol 1 server support removed
+-------------------------------------
+
+sshd(8) no longer supports the old SSH protocol 1, so all the configuration
+options related to it are now deprecated and should be removed from
+/etc/ssh/sshd_config.  These are:
+
+  KeyRegenerationInterval
+  RSAAuthentication
+  RhostsRSAAuthentication
+  ServerKeyBits
+
+The Protocol option is also no longer needed, although it is silently
+ignored rather than deprecated.

+openssh (1:7.6p1-3) UNRELEASED; urgency=medium
+
+  [ Colin Watson ]
+  * Remove the decade-old ssh-krb5 transitional package; upgrades of
+    openssh-server will preserve existing configuration, and new
+    installations should just enable GSSAPIAuthentication and
+    GSSAPIKeyExchange in sshd_config (closes: #878626).
+  * Support the "noudeb" build profile.
+  * Fix putty-transfer regression test.
+
+  [ Anders Kaseorg ]
+  * debian/systemd/ssh-agent.service: Add missing dbus dependency.
+
+  [ Jason Duerstock ]
+  * Add a "pkg.openssh.nognome" build profile, which disables building the
+    ssh-askpass-gnome binary package and avoids the build-dependency on
+    libgtk-3-dev (closes: #883819).

+
+  * Apply upstream patch to fix PermitOpen argument handling.

+
+openssh (1:7.6p1-1) unstable; urgency=medium
+
+  * New upstream release (https://www.openssh.com/txt/release-7.6):
+    - SECURITY: sftp-server(8): In read-only mode, sftp-server was
+      incorrectly permitting creation of zero-length files. Reported by
+      Michal Zalewski.
+    - ssh(1): Delete SSH protocol version 1 support, associated
+      configuration options and documentation (LP: #1584321).
+    - ssh(1)/sshd(8): Remove support for the hmac-ripemd160 MAC.
+    - ssh(1)/sshd(8): Remove support for the arcfour, blowfish and CAST
+      ciphers.
+    - Refuse RSA keys <1024 bits in length and improve reporting for keys
+      that do not meet this requirement.
+    - ssh(1): Do not offer CBC ciphers by default.
+    - ssh(1): Add RemoteCommand option to specify a command in the ssh
+      config file instead of giving it on the client's command line.  This
+      allows the configuration file to specify the command that will be
+      executed on the remote host.
+    - sshd(8): Add ExposeAuthInfo option that enables writing details of the
+      authentication methods used (including public keys where applicable)
+      to a file that is exposed via a $SSH_USER_AUTH environment variable in
+      the subsequent session.
+    - ssh(1): Add support for reverse dynamic forwarding.  In this mode, ssh
+      will act as a SOCKS4/5 proxy and forward connections to destinations
+      requested by the remote SOCKS client.  This mode is requested using
+      extended syntax for the -R and RemoteForward options and, because it
+      is implemented solely at the client, does not require the server be
+      updated to be supported.
+    - sshd(8): Allow LogLevel directive in sshd_config Match blocks.
+    - ssh-keygen(1): Allow inclusion of arbitrary string or flag certificate
+      extensions and critical options.
+    - ssh-keygen(1): Allow ssh-keygen to use a key held in ssh-agent as a CA
+      when signing certificates.
+    - ssh(1)/sshd(8): Allow IPQoS=none in ssh/sshd to not set an explicit
+      ToS/DSCP value and just use the operating system default.
+    - ssh-add(1): Add -q option to make ssh-add quiet on success.
+    - ssh(1): Expand the StrictHostKeyChecking option with two new settings.
+      The first "accept-new" will automatically accept hitherto-unseen keys
+      but will refuse connections for changed or invalid hostkeys.  This is
+      a safer subset of the current behaviour of StrictHostKeyChecking=no.
+      The second setting "off", is a synonym for the current behaviour of
+      StrictHostKeyChecking=no: accept new host keys, and continue
+      connection for hosts with incorrect hostkeys.  A future release will
+      change the meaning of StrictHostKeyChecking=no to the behaviour of
+      "accept-new".
+    - ssh(1): Add SyslogFacility option to ssh(1) matching the equivalent
+      option in sshd(8).
+    - ssh(1): Use HostKeyAlias if specified instead of hostname for matching
+      host certificate principal names.
+    - sftp(1): Implement sorting for globbed ls.
+    - ssh(1): Add a user@host prefix to client's "Permission denied"
+      messages, useful in particular when using "stacked" connections (e.g.
+      ssh -J) where it's not clear which host is denying.
+    - ssh(1): Accept unknown EXT_INFO extension values that contain \0
+      characters.  These are legal, but would previously cause fatal
+      connection errors if received.
+    - sftp(1): Print '?' instead of incorrect link count (that the protocol
+      doesn't provide) for remote listings.
+    - ssh(1): Return failure rather than fatal() for more cases during
+      session multiplexing negotiations.  Causes the session to fall back to
+      a non-mux connection if they occur.
+    - ssh(1): Mention that the server may send debug messages to explain
+      public key authentication problems under some circumstances.
+    - Translate OpenSSL error codes to better report incorrect passphrase
+      errors when loading private keys.
+    - sshd(8): Adjust compatibility patterns for WinSCP to correctly
+      identify versions that implement only the legacy DH group exchange
+      scheme (closes: #877800).
+    - ssh(1): Print the "Killed by signal 1" message only at LogLevel
+      verbose so that it is not shown at the default level; prevents it from
+      appearing during ssh -J and equivalent ProxyCommand configs.
+    - ssh-keygen(1): When generating all hostkeys (ssh-keygen -A), clobber
+      existing keys if they exist but are zero length.  Zero-length keys
+      could previously be made if ssh-keygen failed or was interrupted part
+      way through generating them.
+    - ssh-keyscan(1): Avoid double-close() on file descriptors.
+    - sshd(8): Avoid reliance on shared use of pointers shared between
+      monitor and child sshd processes.
+    - sshd_config(8): Document available AuthenticationMethods.
+    - ssh(1): Avoid truncation in some login prompts.
+    - ssh(1): Make "--" before the hostname terminate argument processing
+      after the hostname too (closes: #873201).
+    - ssh-keygen(1): Switch from aes256-cbc to aes256-ctr for encrypting
+      new-style private keys.
+    - ssh(1): Warn and do not attempt to use keys when the public and
+      private halves do not match.
+    - sftp(1): Don't print verbose error message when ssh disconnects from
+      under sftp.
+    - sshd(8): Fix keepalive scheduling problem: prevent activity on a
+      forwarded port from preventing the keepalive from being sent.
+    - sshd(8): When started without root privileges, don't require the
+      privilege separation user or path to exist.
+    - ssh(1)/sshd(8): Correctness fix for channels implementation: accept
+      channel IDs greater than 0x7FFFFFFF.
+    - sshd(8): Expose list of completed authentication methods to PAM via
+      the SSH_AUTH_INFO_0 PAM environment variable.
+    - ssh(1)/sshd(8): Fix several problems in the tun/tap forwarding code,
+      mostly to do with host/network byte order confusion.
+    - sshd(8): Avoid Linux seccomp violations on ppc64le over the socketcall
+      syscall.
+  * Build-depend on debhelper (>= 9.20160709~) rather than dh-systemd.
+  * Change priorities of ssh and ssh-krb5 binary packages to optional, since
+    "Priority: extra" is now deprecated.
+  * Use HTTPS form of copyright-format URL.
+  * Adjust "Running sshd from inittab" instructions in README.Debian to
+    recommend using service(8) rather than calling the init script directly.
+  * Policy version 4.1.0.
+  * Adjust "Per-connection sshd instances with systemd" instructions in
+    README.Debian to recommend using a drop-in file rather than copying and
+    modifying the ssh.socket unit file.

+
+openssh (1:7.5p1-1) experimental; urgency=medium
+
+  * New upstream release (https://www.openssh.com/txt/release-7.5):
+    - SECURITY: ssh(1), sshd(8): Fix weakness in CBC padding oracle
+      countermeasures that allowed a variant of the attack fixed in OpenSSH
+      7.3 to proceed.  Note that the OpenSSH client disables CBC ciphers by
+      default, sshd offers them as lowest-preference options and will remove
+      them by default entirely in the next release.
+    - This release deprecates the sshd_config UsePrivilegeSeparation option,
+      thereby making privilege separation mandatory (closes: #407754).
+    - The format of several log messages emitted by the packet code has
+      changed to include additional information about the user and their
+      authentication state.  Software that monitors ssh/sshd logs may need
+      to account for these changes.
+    - ssh(1), sshd(8): Support "=-" syntax to easily remove methods from
+      algorithm lists, e.g. Ciphers=-*cbc.
+    - sshd(1): Fix NULL dereference crash when key exchange start messages
+      are sent out of sequence.
+    - ssh(1), sshd(8): Allow form-feed characters to appear in configuration
+      files.
+    - sshd(8): Fix regression in OpenSSH 7.4 support for the server-sig-algs
+      extension, where SHA2 RSA signature methods were not being correctly
+      advertised.
+    - ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in
+      known_hosts processing.
+    - ssh(1): Allow ssh to use certificates accompanied by a private key
+      file but no corresponding plain *.pub public key.
+    - ssh(1): When updating hostkeys using the UpdateHostKeys option, accept
+      RSA keys if HostkeyAlgorithms contains any RSA keytype.  Previously,
+      ssh could ignore RSA keys when only the ssh-rsa-sha2-* methods were
+      enabled in HostkeyAlgorithms and not the old ssh-rsa method.
+    - ssh(1): Detect and report excessively long configuration file lines.
+    - Merge a number of fixes found by Coverity and reported via Redhat and
+      FreeBSD.  Includes fixes for some memory and file descriptor leaks in
+      error paths.
+    - ssh(1), sshd(8): When logging long messages to stderr, don't truncate
+      "\r\n" if the length of the message exceeds the buffer.
+    - ssh(1): Fully quote [host]:port in generated ProxyJump/-J command-
+      line; avoid confusion over IPv6 addresses and shells that treat square
+      bracket characters specially.
+    - Fix various fallout and sharp edges caused by removing SSH protocol 1
+      support from the server, including the server banner string being
+      incorrectly terminated with only \n (instead of \r\n), confusing error
+      messages from ssh-keyscan, and a segfault in sshd if protocol v.1 was
+      enabled for the client and sshd_config contained references to legacy
+      keys.
+    - ssh(1), sshd(8): Free fd_set on connection timeout.
+    - sftp(1): Fix division by zero crash in "df" output when server returns
+      zero total filesystem blocks/inodes.
+    - ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors
+      encountered during key loading to more meaningful error codes.
+    - ssh-keygen(1): Sanitise escape sequences in key comments sent to
+      printf but preserve valid UTF-8 when the locale supports it.
+    - ssh(1), sshd(8): Return reason for port forwarding failures where
+      feasible rather than always "administratively prohibited".
+    - sshd(8): Fix deadlock when AuthorizedKeysCommand or
+      AuthorizedPrincipalsCommand produces a lot of output and a key is
+      matched early.
+    - ssh(1): Fix typo in ~C error message for bad port forward
+      cancellation.
+    - ssh(1): Show a useful error message when included config files can't
+      be opened.
+    - sshd_config(5): Repair accidentally-deleted mention of %k token in
+      AuthorizedKeysCommand.
+    - sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM.
+    - ssh-agent(1): Relax PKCS#11 whitelist to include libexec and common
+      32-bit compatibility library directories.
+    - sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME
+      response handling.
+    - ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted keys.
+      It was not possible to delete them except by specifying their full
+      physical path.
+    - sshd(8): Avoid sandbox errors for Linux S390 systems using an ICA
+      crypto coprocessor.
+    - sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox arg
+      inspection.
+    - ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for various that
+      contain non-printable characters where the codeset in use is ASCII.

+openssh (1:7.4p1-1) unstable; urgency=medium
+
+  * New upstream release (http://www.openssh.com/txt/release-7.4):
+    - ssh(1): Remove 3des-cbc from the client's default proposal.  64-bit
+      block ciphers are not safe in 2016 and we don't want to wait until
+      attacks like SWEET32 are extended to SSH.  As 3des-cbc was the only
+      mandatory cipher in the SSH RFCs, this may cause problems connecting
+      to older devices using the default configuration, but it's highly
+      likely that such devices already need explicit configuration for key
+      exchange and hostkey algorithms already anyway.
+    - sshd(8): When a forced-command appears in both a certificate and an
+      authorized keys/principals command= restriction, sshd will now refuse
+      to accept the certificate unless they are identical.  The previous
+      (documented) behaviour of having the certificate forced-command
+      override the other could be a bit confusing and error-prone.
+    - sshd(8): Remove the UseLogin configuration directive and support for
+      having /bin/login manage login sessions.
+    - CVE-2016-10009: ssh-agent(1): Will now refuse to load PKCS#11 modules
+      from paths outside a trusted whitelist (run-time configurable).
+      Requests to load modules could be passed via agent forwarding and an
+      attacker could attempt to load a hostile PKCS#11 module across the
+      forwarded agent channel: PKCS#11 modules are shared libraries, so this
+      would result in code execution on the system running the ssh-agent if
+      the attacker has control of the forwarded agent-socket (on the host
+      running the sshd server) and the ability to write to the filesystem of
+      the host running ssh-agent (usually the host running the ssh client)
+      (closes: #848714).
+    - CVE-2016-10010: sshd(8): When privilege separation is disabled,
+      forwarded Unix-domain sockets would be created by sshd(8) with the
+      privileges of 'root' instead of the authenticated user.  This release
+      refuses Unix-domain socket forwarding when privilege separation is
+      disabled (Privilege separation has been enabled by default for 14
+      years) (closes: #848715).
+    - CVE-2016-10011: sshd(8): Avoid theoretical leak of host private key
+      material to privilege-separated child processes via realloc() when
+      reading keys.  No such leak was observed in practice for normal-sized
+      keys, nor does a leak to the child processes directly expose key
+      material to unprivileged users (closes: #848716).
+    - CVE-2016-10012: sshd(8): The shared memory manager used by
+      pre-authentication compression support had a bounds checks that could
+      be elided by some optimising compilers.  Additionally, this memory
+      manager was incorrectly accessible when pre-authentication compression
+      was disabled.  This could potentially allow attacks against the
+      privileged monitor process from the sandboxed privilege-separation
+      process (a compromise of the latter would be required first).  This
+      release removes support for pre-authentication compression from
+      sshd(8) (closes: #848717).
+    - SECURITY: sshd(8): Validate address ranges for AllowUser and DenyUsers
+      directives at configuration load time and refuse to accept invalid
+      ones.  It was previously possible to specify invalid CIDR address
+      ranges (e.g. user@127.1.2.3/55) and these would always match, possibly
+      resulting in granting access where it was not intended.
+    - ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the
+      version in PuTTY by Simon Tatham.  This allows a multiplexing client
+      to communicate with the master process using a subset of the SSH
+      packet and channels protocol over a Unix-domain socket, with the main
+      process acting as a proxy that translates channel IDs, etc.  This
+      allows multiplexing mode to run on systems that lack file-descriptor
+      passing (used by current multiplexing code) and potentially, in
+      conjunction with Unix-domain socket forwarding, with the client and
+      multiplexing master process on different machines.  Multiplexing proxy
+      mode may be invoked using "ssh -O proxy ...".
+    - sshd(8): Add a sshd_config DisableForwarding option that disables X11,
+      agent, TCP, tunnel and Unix domain socket forwarding, as well as
+      anything else we might implement in the future.  Like the 'restrict'
+      authorized_keys flag, this is intended to be a simple and future-proof
+      way of restricting an account.
+    - sshd(8), ssh(1): Support the "curve25519-sha256" key exchange method.
+      This is identical to the currently-supported method named
+      "curve25519-sha256@libssh.org".
+    - sshd(8): Improve handling of SIGHUP by checking to see if sshd is
+      already daemonised at startup and skipping the call to daemon(3) if it
+      is.  This ensures that a SIGHUP restart of sshd(8) will retain the
+      same process-ID as the initial execution.  sshd(8) will also now
+      unlink the PidFile prior to SIGHUP restart and re-create it after a
+      successful restart, rather than leaving a stale file in the case of a
+      configuration error.
+    - sshd(8): Allow ClientAliveInterval and ClientAliveCountMax directives
+      to appear in sshd_config Match blocks.
+    - sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match those
+      supported by AuthorizedKeysCommand (key, key type, fingerprint, etc.)
+      and a few more to provide access to the contents of the certificate
+      being offered.
+    - ssh(1): Allow IdentityFile to successfully load and use certificates
+      that have no corresponding bare public key.
+    - ssh(1): Fix public key authentication when multiple authentication is
+      in use and publickey is not just the first method attempted.
+    - ssh(1): Improve reporting when attempting to load keys from PKCS#11
+      tokens with fewer useless log messages and more detail in debug
+      messages.
+    - ssh(1): When tearing down ControlMaster connections, don't pollute
+      stderr when LogLevel=quiet.
+    - sftp(1): On ^Z wait for underlying ssh(1) to suspend before suspending
+      sftp(1) to ensure that ssh(1) restores the terminal mode correctly if
+      suspended during a password prompt.
+    - ssh(1): Avoid busy-wait when ssh(1) is suspended during a password
+      prompt (LP: #1646813).
+    - ssh(1), sshd(8): Correctly report errors during sending of ext-info
+      messages.
+    - sshd(8): Fix NULL-deref crash if sshd(8) received an out-of-sequence
+      NEWKEYS message.
+    - sshd(8): Correct list of supported signature algorithms sent in the
+      server-sig-algs extension.
+    - sshd(8): Fix sending ext_info message if privsep is disabled.
+    - sshd(8): More strictly enforce the expected ordering of privilege
+      separation monitor calls used for authentication and allow them only
+      when their respective authentication methods are enabled in the
+      configuration.
+    - sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet for
+      configuration examples.
+    - On environments configured with Turkish locales, fall back to the
+      C/POSIX locale to avoid errors in configuration parsing caused by that
+      locale's unique handling of the letters 'i' and 'I' (LP: #1638338).
+    - contrib: Add a gnome-ssh-askpass3 with GTK+3 support.
+    - sshd(8): Improve PRNG reseeding across privilege separation and force
+      libcrypto to obtain a high-quality seed before chroot or sandboxing.
+  * Apply "wrap-and-sort -at -f debian/control -f debian/tests/control".
+  * Remove entries related to protocol 1 from the default sshd_config
+    generated on new installations.
+  * Remove some advice related to protocol 1 from README.Debian.
+  * Start handling /etc/ssh/sshd_config using ucf.  The immediate motivation
+    for this is to deal with deprecations of options related to protocol 1,
+    but something like this has been needed for a long time (closes:
+    #419574, #848089):
+    - sshd_config is now a slightly-patched version of upstream's, and only
+      contains non-default settings (closes: #147201).
+    - I've included as many historical md5sums of default versions of
+      sshd_config as I could reconstruct from version control, but I'm sure
+      I've missed some.
+    - Explicitly synchronise the debconf database with the current
+      configuration file state in openssh-server.config, to ensure that the
+      PermitRootLogin setting is properly preserved.
+    - UsePrivilegeSeparation now defaults to the stronger "sandbox" rather
+      than "yes", per upstream.
+  * Remove redundant "GSSAPIDelegateCredentials no" from ssh_config (already
+    the upstream default), and document that setting ServerAliveInterval to
+    300 by default if BatchMode is set is Debian-specific (closes: #765630).
+  * Build gnome-ssh-askpass with GTK+ 3 (LP: #801187).
+  * When running regression tests under autopkgtest, use a non-root user
+    with passwordless sudo.

+openssh (1:7.3p1-1) unstable; urgency=medium
+
+  * New upstream release (http://www.openssh.com/txt/release-7.3):
+    - SECURITY: sshd(8): Mitigate a potential denial-of-service attack
+      against the system's crypt(3) function via sshd(8).  An attacker could
+      send very long passwords that would cause excessive CPU use in
+      crypt(3).  sshd(8) now refuses to accept password authentication
+      requests of length greater than 1024 characters.
+    - SECURITY: ssh(1), sshd(8): Fix observable timing weakness in the CBC
+      padding oracle countermeasures.  Note that CBC ciphers are disabled by
+      default and only included for legacy compatibility.
+    - SECURITY: ssh(1), sshd(8): Improve operation ordering of MAC
+      verification for Encrypt-then-MAC (EtM) mode transport MAC algorithms
+      to verify the MAC before decrypting any ciphertext.  This removes the
+      possibility of timing differences leaking facts about the plaintext,
+      though no such leakage has been observed.
+    - ssh(1): Add a ProxyJump option and corresponding -J command-line flag
+      to allow simplified indirection through a one or more SSH bastions or
+      "jump hosts".
+    - ssh(1): Add an IdentityAgent option to allow specifying specific agent
+      sockets instead of accepting one from the environment.
+    - ssh(1): Allow ExitOnForwardFailure and ClearAllForwardings to be
+      optionally overridden when using ssh -W.
+    - ssh(1), sshd(8): Implement support for the IUTF8 terminal mode as per
+      draft-sgtatham-secsh-iutf8-00 (closes: #337041, LP: #394570).
+    - ssh(1), sshd(8): Add support for additional fixed Diffie-Hellman 2K,
+      4K and 8K groups from draft-ietf-curdle-ssh-kex-sha2-03.
+    - ssh-keygen(1), ssh(1), sshd(8): Support SHA256 and SHA512 RSA
+      signatures in certificates.
+    - ssh(1): Add an Include directive for ssh_config(5) files (closes:
+      #536031).
+    - ssh(1): Permit UTF-8 characters in pre-authentication banners sent
+      from the server.
+    - ssh(1), sshd(8): Reduce the syslog level of some relatively common
+      protocol events from LOG_CRIT.
+    - sshd(8): Refuse AuthenticationMethods="" in configurations and accept
+      AuthenticationMethods=any for the default behaviour of not requiring
+      multiple authentication.
+    - sshd(8): Remove obsolete and misleading "POSSIBLE BREAK-IN ATTEMPT!"
+      message when forward and reverse DNS don't match.
+    - ssh(1): Deduplicate LocalForward and RemoteForward entries to fix
+      failures when both ExitOnForwardFailure and hostname canonicalisation
+      are enabled.
+    - sshd(8): Remove fallback from moduli to obsolete "primes" file that
+      was deprecated in 2001 (LP: #1528251).
+    - sshd_config(5): Correct description of UseDNS: it affects ssh hostname
+      processing for authorized_keys, not known_hosts.
+    - sshd(8): Send ClientAliveInterval pings when a time-based RekeyLimit
+      is set; previously keepalive packets were not being sent.
+    - sshd(8): Whitelist more architectures to enable the seccomp-bpf
+      sandbox.
+    - scp(1): Respect the local user's LC_CTYPE locale (closes: #396295).
+    - Take character display widths into account for the progressmeter

+
+  * New upstream release (http://www.openssh.com/txt/release-7.2):
+    - This release disables a number of legacy cryptographic algorithms by
+      default in ssh:
+      + Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and
+        the rijndael-cbc aliases for AES.
+      + MD5-based and truncated HMAC algorithms.
+      These algorithms are already disabled by default in sshd.
+    - ssh(1), sshd(8): Remove unfinished and unused roaming code (was
+      already forcibly disabled in OpenSSH 7.1p2).
+    - ssh(1): Eliminate fallback from untrusted X11 forwarding to trusted
+      forwarding when the X server disables the SECURITY extension.
+    - ssh(1), sshd(8): Increase the minimum modulus size supported for
+      diffie-hellman-group-exchange to 2048 bits.
+    - sshd(8): Pre-auth sandboxing is now enabled by default (previous
+      releases enabled it for new installations via sshd_config).
+    - all: Add support for RSA signatures using SHA-256/512 hash algorithms
+      based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt.
+    - ssh(1): Add an AddKeysToAgent client option which can be set to 'yes',
+      'no', 'ask', or 'confirm', and defaults to 'no'.  When enabled, a
+      private key that is used during authentication will be added to
+      ssh-agent if it is running (with confirmation enabled if set to
+      'confirm').
+    - sshd(8): Add a new authorized_keys option "restrict" that includes all
+      current and future key restrictions (no-*-forwarding, etc.).  Also add
+      permissive versions of the existing restrictions, e.g.  "no-pty" ->
+      "pty".  This simplifies the task of setting up restricted keys and
+      ensures they are maximally-restricted, regardless of any permissions
+      we might implement in the future.
+    - ssh(1): Add ssh_config CertificateFile option to explicitly list
+      certificates.
+    - ssh-keygen(1): Allow ssh-keygen to change the key comment for all
+      supported formats (closes: #811125).
+    - ssh-keygen(1): Allow fingerprinting from standard input, e.g.

+    - ssh-keygen(1): Allow fingerprinting multiple public keys in a file,
+      e.g. "ssh-keygen -lf ~/.ssh/authorized_keys".
+    - sshd(8): Support "none" as an argument for sshd_config Foreground and
+      ChrootDirectory.  Useful inside Match blocks to override a global
+      default.
+    - ssh-keygen(1): Support multiple certificates (one per line) and
+      reading from standard input (using "-f -") for "ssh-keygen -L"
+    - ssh-keyscan(1): Add "ssh-keyscan -c ..." flag to allow fetching
+      certificates instead of plain keys.
+    - ssh(1): Better handle anchored FQDNs (e.g. 'cvs.openbsd.org.') in
+      hostname canonicalisation - treat them as already canonical and remove
+      the trailing '.' before matching ssh_config.
+    - sftp(1): Existing destination directories should not terminate
+      recursive uploads (regression in OpenSSH 6.8; LP: #1553378).
+  * Use HTTPS for Vcs-* URLs, and link to cgit rather than gitweb.

+
+openssh (1:7.1p1-1) unstable; urgency=medium
+
+  * New upstream release (http://www.openssh.com/txt/release-7.0, closes:
+    #785190):
+    - Support for the legacy SSH version 1 protocol is disabled by default
+      at compile time.
+    - Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is
+      disabled by default at run-time.  It may be re-enabled using the
+      instructions at http://www.openssh.com/legacy.html
+    - Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by
+      default at run-time.  These may be re-enabled using the instructions
+      at http://www.openssh.com/legacy.html
+    - Support for the legacy v00 cert format has been removed.
+    - The default for the sshd_config(5) PermitRootLogin option has changed
+      from "yes" to "prohibit-password".
+    - PermitRootLogin=without-password/prohibit-password now bans all
+      interactive authentication methods, allowing only public-key,
+      hostbased and GSSAPI authentication (previously it permitted
+      keyboard-interactive and password-less authentication if those were
+      enabled).
+    - ssh_config(5): Add PubkeyAcceptedKeyTypes option to control which
+      public key types are available for user authentication.
+    - sshd_config(5): Add HostKeyAlgorithms option to control which public
+      key types are offered for host authentications.
+    - ssh(1), sshd(8): Extend Ciphers, MACs, KexAlgorithms,
+      HostKeyAlgorithms, PubkeyAcceptedKeyTypes and HostbasedKeyTypes
+      options to allow appending to the default set of algorithms instead of
+      replacing it.  Options may now be prefixed with a '+' to append to the
+      default, e.g. "HostKeyAlgorithms=+ssh-dss".
+    - sshd_config(5): PermitRootLogin now accepts an argument of
+      'prohibit-password' as a less-ambiguous synonym of 'without-
+      password'.
+    - ssh(1), sshd(8): Add compatability workarounds for Cisco and more
+      PuTTY versions.
+    - Fix some omissions and errors in the PROTOCOL and PROTOCOL.mux
+      documentation relating to Unix domain socket forwarding.
+    - ssh(1): Improve the ssh(1) manual page to include a better description
+      of Unix domain socket forwarding (closes: #779068).
+    - ssh(1), ssh-agent(1): Skip uninitialised PKCS#11 slots, fixing
+      failures to load keys when they are present.
+    - ssh(1), ssh-agent(1): Do not ignore PKCS#11 hosted keys that wth empty
+      CKA_ID.
+    - sshd(8): Clarify documentation for UseDNS option.
+    - Check realpath(3) behaviour matches what sftp-server requires and use
+      a replacement if necessary.
+  * New upstream release (http://www.openssh.com/txt/release-7.1):
+    - sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin=
+      prohibit-password/without-password that could, depending on
+      compile-time configuration, permit password authentication to root
+      while preventing other forms of authentication.  This problem was
+      reported by Mantas Mikulenas.
+    - ssh(1), sshd(8): Add compatibility workarounds for FuTTY.
+    - ssh(1), sshd(8): Refine compatibility workarounds for WinSCP.
+    - Fix a number of memory faults (double-free, free of uninitialised
+      memory, etc) in ssh(1) and ssh-keygen(1).  Reported by Mateusz
+      Kocielski.
+  * Change "PermitRootLogin without-password" to the new preferred spelling
+    of "PermitRootLogin prohibit-password" in sshd_config, and update
+    documentation to reflect the new upstream default.
+  * Enable conch interoperability tests under autopkgtest.

+
+openssh (1:6.9p1-1) unstable; urgency=medium
+
+  * New upstream release (http://www.openssh.com/txt/release-6.8):
+    - sshd(8): UseDNS now defaults to 'no'.  Configurations that match
+      against the client host name (via sshd_config or authorized_keys) may
+      need to re-enable it or convert to matching against addresses.
+    - Add FingerprintHash option to ssh(1) and sshd(8), and equivalent
+      command-line flags to the other tools to control algorithm used for
+      key fingerprints.  The default changes from MD5 to SHA256 and format
+      from hex to base64.
+      Fingerprints now have the hash algorithm prepended.  An example of the
+      new format: SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE
+      Please note that visual host keys will also be different.
+    - ssh(1), sshd(8): Experimental host key rotation support.  Add a
+      protocol extension for a server to inform a client of all its
+      available host keys after authentication has completed.  The client
+      may record the keys in known_hosts, allowing it to upgrade to better
+      host key algorithms and a server to gracefully rotate its keys.
+      The client side of this is controlled by a UpdateHostkeys config
+      option (default off).
+    - ssh(1): Add a ssh_config HostbasedKeyType option to control which host
+      public key types are tried during host-based authentication.
+    - ssh(1), sshd(8): Fix connection-killing host key mismatch errors when
+      sshd offers multiple ECDSA keys of different lengths.
+    - ssh(1): When host name canonicalisation is enabled, try to parse host
+      names as addresses before looking them up for canonicalisation.  Fixes
+      bz#2074 and avoids needless DNS lookups in some cases.
+    - ssh(1), ssh-keysign(8): Make ed25519 keys work for host based
+      authentication.
+    - sshd(8): SSH protocol v.1 workaround for the Meyer, et al,
+      Bleichenbacher Side Channel Attack.  Fake up a bignum key before RSA
+      decryption.
+    - sshd(8): Remember which public keys have been used for authentication
+      and refuse to accept previously-used keys.  This allows
+      AuthenticationMethods=publickey,publickey to require that users
+      authenticate using two _different_ public keys.
+    - sshd(8): add sshd_config HostbasedAcceptedKeyTypes and
+      PubkeyAcceptedKeyTypes options to allow sshd to control what public
+      key types will be accepted (closes: #481133).  Currently defaults to
+      all.
+    - sshd(8): Don't count partial authentication success as a failure
+      against MaxAuthTries.
+    - ssh(1): Add RevokedHostKeys option for the client to allow text-file
+      or KRL-based revocation of host keys.
+    - ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates by serial
+      number or key ID without scoping to a particular CA.
+    - ssh(1): Add a "Match canonical" criteria that allows ssh_config Match
+      blocks to trigger only in the second config pass.
+    - ssh(1): Add a -G option to ssh that causes it to parse its
+      configuration and dump the result to stdout, similar to "sshd -T".
+    - ssh(1): Allow Match criteria to be negated. E.g. "Match !host".
+    - ssh-keyscan(1): ssh-keyscan has been made much more robust against
+      servers that hang or violate the SSH protocol (closes: #241119).
+    - ssh(1), ssh-keygen(1): Fix regression bz#2306: Key path names were
+      being lost as comment fields (closes: #787776).
+    - ssh(1): Allow ssh_config Port options set in the second config parse
+      phase to be applied (they were being ignored; closes: #774369).
+    - ssh(1): Tweak config re-parsing with host canonicalisation - make the
+      second pass through the config files always run when host name
+      canonicalisation is enabled (and not whenever the host name changes)
+    - ssh(1): Fix passing of wildcard forward bind addresses when connection
+      multiplexing is in use.
+    - ssh-keygen(1): Fix broken private key conversion from non-OpenSSH
+      formats.
+    - ssh-keygen(1): Fix KRL generation bug when multiple CAs are in use.
+  * New upstream release (http://www.openssh.com/txt/release-6.9):
+    - CVE-2015-5352: ssh(1): When forwarding X11 connections with
+      ForwardX11Trusted=no, connections made after ForwardX11Timeout expired
+      could be permitted and no longer subject to XSECURITY restrictions
+      because of an ineffective timeout check in ssh(1) coupled with "fail
+      open" behaviour in the X11 server when clients attempted connections
+      with expired credentials (closes: #790798).  This problem was reported
+      by Jann Horn.
+    - SECURITY: ssh-agent(1): Fix weakness of agent locking (ssh-add -x) to
+      password guessing by implementing an increasing failure delay, storing
+      a salted hash of the password rather than the password itself and
+      using a timing-safe comparison function for verifying unlock attempts.
+      This problem was reported by Ryan Castellucci.
+    - sshd(8): Support admin-specified arguments to AuthorizedKeysCommand
+      (closes: #740494).
+    - sshd(8): Add AuthorizedPrincipalsCommand that allows retrieving
+      authorized principals information from a subprocess rather than a
+      file.
+    - ssh(1), ssh-add(1): Support PKCS#11 devices with external PIN entry
+      devices.
+    - ssh-keygen(1): Support "ssh-keygen -lF hostname" to search known_hosts
+      and print key hashes rather than full keys.
+    - ssh-agent(1): Add -D flag to leave ssh-agent in foreground without
+      enabling debug mode.
+    - ssh(1), sshd(8): Deprecate legacy SSH2_MSG_KEX_DH_GEX_REQUEST_OLD
+      message and do not try to use it against some 3rd-party SSH
+      implementations that use it (older PuTTY, WinSCP).
+    - ssh(1), sshd(8): Cap DH-GEX group size at 4Kbits for Cisco

+    - sshd(8): Fix post-auth crash with permitopen=none (closes: #778807).
+    - ssh(1), ssh-add(1), ssh-keygen(1): Allow new-format private keys to be
+      encrypted with AEAD ciphers.
+    - ssh(1): Allow ListenAddress, Port and AddressFamily configuration
+      options to appear in any order.
+    - sshd(8): Check for and reject missing arguments for VersionAddendum
+      and ForceCommand.
+    - ssh(1), sshd(8): Don't treat unknown certificate extensions as fatal.

+      forwarding requested.
+    - sshd(8): Correctly record login when UseLogin is set.
+    - sshd(8): Add some missing options to sshd -T output and fix output of
+      VersionAddendum and HostCertificate.
+    - Document and improve consistency of options that accept a "none"
+      argument: TrustedUserCAKeys, RevokedKeys, AuthorizedPrincipalsFile.
+    - ssh(1): Include remote username in debug output.
+    - sshd(8): Avoid compatibility problem with some versions of Tera Term,
+      which would crash when they received the hostkeys notification message
+      (hostkeys-00@openssh.com).
+    - sshd(8): Mention ssh-keygen -E as useful when comparing legacy MD5
+      host key fingerprints.
+    - ssh(1): Clarify pseudo-terminal request behaviour and make manual
+      language consistent.
+    - ssh(1): Document that the TERM environment variable is not subject to
+      SendEnv and AcceptEnv; bz#2386
+    - sshd(8): Format UsePAM setting when using sshd -T (closes: #767648).
+    - moduli(5): Update DH-GEX moduli (closes: #787037).
+  * There are some things I want to fix before upgrading to 7.0p1, though I
+    intend to do that soon.  In the meantime, backport some patches, mainly
+    to fix security issues:
+    - SECURITY: sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be
+      world-writable.  Local attackers may be able to write arbitrary
+      messages to logged-in users, including terminal escape sequences.
+      Reported by Nikolay Edigaryev.
+    - SECURITY: sshd(8): Fixed a privilege separation weakness related to
+      PAM support.  Attackers who could successfully compromise the
+      pre-authentication process for remote code execution and who had valid
+      credentials on the host could impersonate other users.  Reported by
+      Moritz Jodeit.
+    - SECURITY: sshd(8): Fixed a use-after-free bug related to PAM support
+      that was reachable by attackers who could compromise the
+      pre-authentication process for remote code execution (closes:
+      #795711).  Also reported by Moritz Jodeit.
+    - CVE-2015-5600: sshd(8): Fix circumvention of MaxAuthTries using
+      keyboard-interactive authentication (closes: #793616).  By specifying
+      a long, repeating keyboard-interactive "devices" string, an attacker
+      could request the same authentication method be tried thousands of
+      times in a single pass.  The LoginGraceTime timeout in sshd(8) and any
+      authentication failure delays implemented by the authentication
+      mechanism itself were still applied.  Found by Kingcope.
+    - Let principals-command.sh work for noexec /var/run.
+  * Thanks to Jakub Jelen of Red Hat for Fedora's rebased version of the

+
+  * New upstream release (http://www.openssh.com/txt/release-6.7):
+    - sshd(8): The default set of ciphers and MACs has been altered to
+      remove unsafe algorithms.  In particular, CBC ciphers and arcfour* are
+      disabled by default.  The full set of algorithms remains available if
+      configured explicitly via the Ciphers and MACs sshd_config options.
+    - ssh(1), sshd(8): Add support for Unix domain socket forwarding.  A
+      remote TCP port may be forwarded to a local Unix domain socket and
+      vice versa or both ends may be a Unix domain socket (closes: #236718).
+    - ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for ED25519
+      key types.
+    - sftp(1): Allow resumption of interrupted uploads.
+    - ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it is
+      the same as the one sent during initial key exchange.
+    - sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind addresses
+      when GatewayPorts=no; allows client to choose address family.
+    - sshd(8): Add a sshd_config PermitUserRC option to control whether
+      ~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys
+      option.
+    - ssh(1): Add a %C escape sequence for LocalCommand and ControlPath that
+      expands to a unique identifier based on a hash of the tuple of (local
+      host, remote user, hostname, port).  Helps avoid exceeding miserly
+      pathname limits for Unix domain sockets in multiplexing control paths.
+    - sshd(8): Make the "Too many authentication failures" message include
+      the user, source address, port and protocol in a format similar to the
+      authentication success / failure messages.
+    - Use CLOCK_BOOTTIME in preference to CLOCK_MONOTONIC when it is
+      available. It considers time spent suspended, thereby ensuring
+      timeouts (e.g. for expiring agent keys) fire correctly (closes:
+      #734553).
+    - Use prctl() to prevent sftp-server from accessing
+      /proc/self/{mem,maps}.
+  * Restore TCP wrappers support, removed upstream in 6.7.  It is true that
+    dropping this reduces preauth attack surface in sshd.  On the other
+    hand, this support seems to be quite widely used, and abruptly dropping
+    it (from the perspective of users who don't read openssh-unix-dev) could
+    easily cause more serious problems in practice.  It's not entirely clear
+    what the right long-term answer for Debian is, but it at least probably
+    doesn't involve dropping this feature shortly before a freeze.
+  * Replace patch to disable OpenSSL version check with an updated version
+    of Kurt Roeckx's patch from #732940 to just avoid checking the status

+  * Build-depend on a new enough dpkg-dev for dpkg-buildflags, rather than

+  * Change start condition of Upstart job to be just the standard "runlevel

+    it unreasonably difficult to ensure that urandom starts before ssh, and
+    is not really necessary since one of static-network-up and failsafe-boot
+    is guaranteed to happen and will trigger entry to the default runlevel,
+    and we don't care about ssh starting before the network (LP: #1098299).
+  * Drop conffile handling for direct upgrades from pre-split ssh package;
+    this was originally added in 1:4.3p2-7 / 1:4.3p2-8, and contained a

+  * Switch to new unified layout for Upstart jobs as documented in
+    https://wiki.ubuntu.com/UpstartCompatibleInitScripts: the init script
+    checks for a running Upstart, and we now let dh_installinit handle most
+    of the heavy lifting in maintainer scripts.  Ubuntu users should be
+    essentially unaffected except that sshd may no longer start
+    automatically in chroots if the running Upstart predates 0.9.0; but the
+    main goal is simply not to break when openssh-server is installed in a
+    chroot.
+  * Remove the check for vulnerable host keys; this was first added five
+    years ago, and everyone should have upgraded through a version that
+    applied these checks by now.  The ssh-vulnkey tool and the blacklisting
+    support in sshd are still here, at least for the moment.

+
+  * New upstream release (http://www.openssh.com/txt/release-5.9).
+    - Introduce sandboxing of the pre-auth privsep child using an optional
+      sshd_config(5) "UsePrivilegeSeparation=sandbox" mode that enables
+      mandatory restrictions on the syscalls the privsep child can perform.
+    - Add new SHA256-based HMAC transport integrity modes from
+      http://www.ietf.org/id/draft-dbider-sha2-mac-for-ssh-02.txt.
+    - The pre-authentication sshd(8) privilege separation slave process now
+      logs via a socket shared with the master process, avoiding the need to
+      maintain /dev/log inside the chroot (closes: #75043, #429243,
+      #599240).
+    - ssh(1) now warns when a server refuses X11 forwarding (closes:
+      #504757).
+    - sshd_config(5)'s AuthorizedKeysFile now accepts multiple paths,
+      separated by whitespace (closes: #76312).  The authorized_keys2
+      fallback is deprecated but documented (closes: #560156).
+    - ssh(1) and sshd(8): set IPv6 traffic class from IPQoS, as well as IPv4
+      ToS/DSCP (closes: #498297).
+    - ssh-add(1) now accepts keys piped from standard input.  E.g. "ssh-add
+      - < /path/to/key" (closes: #229124).
+    - Clean up lost-passphrase text in ssh-keygen(1) (closes: #444691).
+    - Say "required" rather than "recommended" in unprotected-private-key
+      warning (LP: #663455).

+
+  * New upstream release (http://www.openssh.com/txt/release-5.7):
+    - Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
+      and host/user keys (ECDSA) as specified by RFC5656.  ECDH and ECDSA
+      offer better performance than plain DH and DSA at the same equivalent
+      symmetric key length, as well as much shorter keys.
+    - sftp(1)/sftp-server(8): add a protocol extension to support a hard
+      link operation.  It is available through the "ln" command in the
+      client.  The old "ln" behaviour of creating a symlink is available
+      using its "-s" option or through the preexisting "symlink" command.
+    - scp(1): Add a new -3 option to scp: Copies between two remote hosts
+      are transferred through the local host (closes: #508613).
+    - ssh(1): "atomically" create the listening mux socket by binding it on
+      a temporary name and then linking it into position after listen() has
+      succeeded.  This allows the mux clients to determine that the server
+      socket is either ready or stale without races (closes: #454784).
+      Stale server sockets are now automatically removed (closes: #523250).
+    - ssh(1): install a SIGCHLD handler to reap expired child process
+      (closes: #594687).
+    - ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
+      temporary directories (closes: #357469, although only if you arrange
+      for ssh-agent to actually see $TMPDIR since the setgid bit will cause
+      it to be stripped off).
+  * Update to current GSSAPI patch from
+    http://www.sxw.org.uk/computing/patches/openssh-5.7p1-gsskex-all-20110125.patch:
+    - Add GSSAPIServerIdentity option.
+  * Generate ECDSA host keys on fresh installations.  Upgraders who wish to
+    add such host keys should manually add 'HostKey
+    /etc/ssh/ssh_host_ecdsa_key' to /etc/ssh/sshd_config and run 'ssh-keygen
+    -q -f /etc/ssh/ssh_host_ecdsa_key -N "" -t ecdsa'.
+  * Build-depend on libssl-dev (>= 0.9.8g) to ensure sufficient ECC support.
+  * Backport SELinux build fix from CVS.
+  * Rearrange selinux-role.patch so that it links properly given this
+    SELinux build fix.

+
+  * New upstream release (LP: #535029).
+    - After a transition period of about 10 years, this release disables SSH
+      protocol 1 by default.  Clients and servers that need to use the
+      legacy protocol must explicitly enable it in ssh_config / sshd_config
+      or on the command-line.
+    - Remove the libsectok/OpenSC-based smartcard code and add support for
+      PKCS#11 tokens.  This support is enabled by default in the Debian
+      packaging, since it now doesn't involve additional library
+      dependencies (closes: #231472, LP: #16918).
+    - Add support for certificate authentication of users and hosts using a
+      new, minimal OpenSSH certificate format (closes: #482806).
+    - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...".
+    - Add the ability to revoke keys in sshd(8) and ssh(1).  (For the Debian
+      package, this overlaps with the key blacklisting facility added in
+      openssh 1:4.7p1-9, but with different file formats and slightly
+      different scopes; for the moment, I've roughly merged the two.)
+    - Various multiplexing improvements, including support for requesting
+      port-forwardings via the multiplex protocol (closes: #360151).
+    - Allow setting an explicit umask on the sftp-server(8) commandline to
+      override whatever default the user has (closes: #496843).
+    - Many sftp client improvements, including tab-completion, more options,
+      and recursive transfer support for get/put (LP: #33378).  The old
+      mget/mput commands never worked properly and have been removed
+      (closes: #270399, #428082).
+    - Do not prompt for a passphrase if we fail to open a keyfile, and log
+      the reason why the open failed to debug (closes: #431538).
+    - Prevent sftp from crashing when given a "-" without a command.  Also,
+      allow whitespace to follow a "-" (closes: #531561).
+
+  * Fix 'debian/rules quilt-setup' to avoid writing .orig files if some
+    patches apply with offsets.
+  * Include debian/ssh-askpass-gnome.png in the Debian tarball now that
+    we're using a source format that permits this, rather than messing
+    around with uudecode.
+  * Drop compatibility with the old gssapi mechanism used in ssh-krb5 <<
+    3.8.1p1-1.  Simon Wilkinson refused this patch since the old gssapi
+    mechanism was removed due to a serious security hole, and since these
+    versions of ssh-krb5 are no longer security-supported by Debian I don't
+    think there's any point keeping client compatibility for them.
+  * Fix substitution of ETC_PAM_D_SSH, following the rename in 1:4.7p1-4.
+  * Hardcode the location of xauth to /usr/bin/xauth rather than
+    /usr/bin/X11/xauth (thanks, Aron Griffis; closes: #575725, LP: #8440).
+    xauth no longer depends on x11-common, so we're no longer guaranteed to
+    have the /usr/bin/X11 symlink available.  I was taking advantage of the
+    /usr/bin/X11 symlink to smooth X's move to /usr/bin, but this is far
+    enough in the past now that it's probably safe to just use /usr/bin.
+  * Remove SSHD_OOM_ADJUST configuration.  sshd now unconditionally makes
+    itself non-OOM-killable, and doesn't require configuration to avoid log
+    spam in virtualisation containers (closes: #555625).
+  * Drop Debian-specific removal of OpenSSL version check.  Upstream ignores
+    the two patchlevel nybbles now, which is sufficient to address the
+    original reason this change was introduced, and it appears that any
+    change in the major/minor/fix nybbles would involve a new libssl package
+    name.  (We'd still lose if the status nybble were ever changed, but that
+    would mean somebody had packaged a development/beta version rather than
+    a proper release, which doesn't appear to be normal practice.)
+  * Drop most of our "LogLevel SILENT" (-qq) patch.  This was originally
+    introduced to match the behaviour of non-free SSH, in which -q does not
+    suppress fatal errors, but matching the behaviour of OpenSSH upstream is
+    much more important nowadays.  We no longer document that -q does not
+    suppress fatal errors (closes: #280609).  Migrate "LogLevel SILENT" to
+    "LogLevel QUIET" in sshd_config on upgrade.
+  * Policy version 3.8.4:
+    - Add a Homepage field.

+    - Change the default cipher order to prefer the AES CTR modes and the

+
+  * New upstream release (closes: #474301). Important changes not previously
+    backported to 4.7p1:
+    - 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9):
+      + Added chroot(2) support for sshd(8), controlled by a new option
+        "ChrootDirectory" (closes: #139047, LP: #24777).
+      + Linked sftp-server(8) into sshd(8). The internal sftp server is used
+        when the command "internal-sftp" is specified in a Subsystem or
+        ForceCommand declaration. When used with ChrootDirectory, the
+        internal sftp server requires no special configuration of files
+        inside the chroot environment.
+      + Added a protocol extension method "posix-rename@openssh.com" for
+        sftp-server(8) to perform POSIX atomic rename() operations; sftp(1)
+        prefers this if available (closes: #308561).
+      + Removed the fixed limit of 100 file handles in sftp-server(8).
+      + ssh(8) will now skip generation of SSH protocol 1 ephemeral server
+        keys when in inetd mode and protocol 2 connections are negotiated.
+        This speeds up protocol 2 connections to inetd-mode servers that
+        also allow Protocol 1.
+      + Accept the PermitRootLogin directive in a sshd_config(5) Match
+        block. Allows for, e.g. permitting root only from the local network.
+      + Reworked sftp(1) argument splitting and escaping to be more
+        internally consistent (i.e. between sftp commands) and more
+        consistent with sh(1). Please note that this will change the
+        interpretation of some quoted strings, especially those with
+        embedded backslash escape sequences.
+      + Support "Banner=none" in sshd_config(5) to disable sending of a
+        pre-login banner (e.g. in a Match block).
+      + ssh(1) ProxyCommands are now executed with $SHELL rather than
+        /bin/sh.
+      + ssh(1)'s ConnectTimeout option is now applied to both the TCP
+        connection and the SSH banner exchange (previously it just covered
+        the TCP connection). This allows callers of ssh(1) to better detect
+        and deal with stuck servers that accept a TCP connection but don't
+        progress the protocol, and also makes ConnectTimeout useful for
+        connections via a ProxyCommand.
+      + scp(1) incorrectly reported "stalled" on slow copies (closes:
+        #140828).
+      + scp(1) date underflow for timestamps before epoch.
+      + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS,
+        instead of the current standard RRSIG.
+      + Correctly drain ACKs when a sftp(1) upload write fails midway,
+        avoids a fatal() exit from what should be a recoverable condition.
+      + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF
+        hostname") to not include any IP address in the data to be hashed.
+      + Make ssh(1) skip listening on the IPv6 wildcard address when a
+        binding address of 0.0.0.0 is used against an old SSH server that
+        does not support the RFC4254 syntax for wildcard bind addresses.
+      + Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is
+        already done for X11/TCP forwarding sockets (closes: #439661).
+      + Fix FD leak that could hang a ssh(1) connection multiplexing master.
+      + Make ssh(1) -q option documentation consistent with reality.
+      + Fixed sshd(8) PAM support not calling pam_session_close(), or
+        failing to call it with root privileges (closes: #372680).
+      + Fix activation of OpenSSL engine support when requested in configure
+        (LP: #119295).
+      + Cache SELinux status earlier so we know if it's enabled after a
+        chroot (LP: #237557).
+    - 5.1/5.1p1 (http://www.openssh.com/txt/release-5.1):
+      + Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1)
+        and ssh-keygen(1). Visual fingerprint display is controlled by a new
+        ssh_config(5) option "VisualHostKey". The intent is to render SSH
+        host keys in a visual form that is amenable to easy recall and
+        rejection of changed host keys.
+      + sshd_config(5) now supports CIDR address/masklen matching in "Match
+        address" blocks, with a fallback to classic wildcard matching.
+      + sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys
+        from="..." restrictions, also with a fallback to classic wildcard
+        matching.
+      + Added an extended test mode (-T) to sshd(8) to request that it write
+        its effective configuration to stdout and exit. Extended test mode
+        also supports the specification of connection parameters (username,
+        source address and hostname) to test the application of
+        sshd_config(5) Match rules. 
+      + ssh(1) now prints the number of bytes transferred and the overall
+        connection throughput for SSH protocol 2 sessions when in verbose
+        mode (previously these statistics were displayed for protocol 1
+        connections only).
+      + sftp-server(8) now supports extension methods statvfs@openssh.com
+        and fstatvfs@openssh.com that implement statvfs(2)-like operations.
+      + sftp(1) now has a "df" command to the sftp client that uses the
+        statvfs@openssh.com to produce a df(1)-like display of filesystem
+        space and inode utilisation (requires statvfs@openssh.com support on
+        the server).
+      + Added a MaxSessions option to sshd_config(5) to allow control of the
+        number of multiplexed sessions supported over a single TCP
+        connection. This allows increasing the number of allowed sessions
+        above the previous default of 10, disabling connection multiplexing
+        (MaxSessions=1) or disallowing login/shell/subsystem sessions
+        entirely (MaxSessions=0).
+      + Added a no-more-sessions@openssh.com global request extension that
+        is sent from ssh(1) to sshd(8) when the client knows that it will
+        never request another session (i.e. when session multiplexing is
+        disabled). This allows a server to disallow further session requests
+        and terminate the session in cases where the client has been
+        hijacked.
+      + ssh-keygen(1) now supports the use of the -l option in combination
+        with -F to search for a host in ~/.ssh/known_hosts and display its
+        fingerprint.
+      + ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of
+        "rsa1" (LP: #129794).
+      + Added an AllowAgentForwarding option to sshd_config(8) to control
+        whether authentication agent forwarding is permitted. Note that this
+        is a loose control, as a client may install their own unofficial
+        forwarder.
+      + ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when
+        receiving network data, resulting in a ~10% speedup.
+      + ssh(1) and sshd(8) will now try additional addresses when connecting
+        to a port forward destination whose DNS name resolves to more than
+        one address. The previous behaviour was to try the only first
+        address and give up if that failed.
+      + ssh(1) and sshd(8) now support signalling that channels are
+        half-closed for writing, through a channel protocol extension
+        notification "eow@openssh.com". This allows propagation of closed
+        file descriptors, so that commands such as "ssh -2 localhost od
+        /bin/ls | true" do not send unnecessary data over the wire.
+      + sshd(8): increased the default size of ssh protocol 1 ephemeral keys
+        from 768 to 1024 bits.
+      + When ssh(1) has been requested to fork after authentication ("ssh
+        -f") with ExitOnForwardFailure enabled, delay the fork until after
+        replies for any -R forwards have been seen. Allows for robust
+        detection of -R forward failure when using -f.
+      + "Match group" blocks in sshd_config(5) now support negation of
+        groups. E.g. "Match group staff,!guests".
+      + sftp(1) and sftp-server(8) now allow chmod-like operations to set
+        set[ug]id/sticky bits.
+      + The MaxAuthTries option is now permitted in sshd_config(5) match
+        blocks.
+      + Multiplexed ssh(1) sessions now support a subset of the ~ escapes
+        that are available to a primary connection.
+      + ssh(1) connection multiplexing will now fall back to creating a new
+        connection in most error cases (closes: #352830).
+      + Make ssh(1) deal more gracefully with channel requests that fail.
+        Previously it would optimistically assume that requests would always
+        succeed, which could cause hangs if they did not (e.g. when the
+        server runs out of file descriptors).
+      + ssh(1) now reports multiplexing errors via the multiplex slave's
+        stderr where possible (subject to LogLevel in the mux master).
+      + Fixed an UMAC alignment problem that manifested on Itanium
+        platforms.
+  * Remove our local version of moduli(5) now that there's one upstream.
+  * Say "GTK+" rather than "GTK" in ssh-askpass-gnome's description.
+  * Add lintian overrides for empty /usr/share/doc/openssh-client
+    directories in openssh-server and ssh (necessary due to being symlink
+    targets).

+  * New upstream release (closes: #453367).
+    - CVE-2007-4752: Prevent ssh(1) from using a trusted X11 cookie if
+      creation of an untrusted cookie fails; found and fixed by Jan Pechanec
+      (closes: #444738).
+    - sshd(8) in new installations defaults to SSH Protocol 2 only. Existing
+      installations are unchanged.
+    - The SSH channel window size has been increased, and both ssh(1)
+      sshd(8) now send window updates more aggressively. These improves
+      performance on high-BDP (Bandwidth Delay Product) networks.
+    - ssh(1) and sshd(8) now preserve MAC contexts between packets, which
+      saves 2 hash calls per packet and results in 12-16% speedup for
+      arcfour256/hmac-md5.
+    - A new MAC algorithm has been added, UMAC-64 (RFC4418) as
+      "umac-64@openssh.com". UMAC-64 has been measured to be approximately
+      20% faster than HMAC-MD5.
+    - Failure to establish a ssh(1) TunnelForward is now treated as a fatal
+      error when the ExitOnForwardFailure option is set.
+    - ssh(1) returns a sensible exit status if the control master goes away
+      without passing the full exit status.
+    - When using a ProxyCommand in ssh(1), set the outgoing hostname with
+      gethostname(2), allowing hostbased authentication to work.
+    - Make scp(1) skip FIFOs rather than hanging (closes: #246774).
+    - Encode non-printing characters in scp(1) filenames. These could cause
+      copies to be aborted with a "protocol error".
+    - Handle SIGINT in sshd(8) privilege separation child process to ensure
+      that wtmp and lastlog records are correctly updated.
+    - Report GSSAPI mechanism in errors, for libraries that support multiple
+      mechanisms.
+    - Improve documentation for ssh-add(1)'s -d option.
+    - Rearrange and tidy GSSAPI code, removing server-only code being linked
+      into the client.
+    - Delay execution of ssh(1)'s LocalCommand until after all forwardings
+      have been established.
+    - In scp(1), do not truncate non-regular files.
+    - Improve exit message from ControlMaster clients.
+    - Prevent sftp-server(8) from reading until it runs out of buffer space,
+      whereupon it would exit with a fatal error (closes: #365541).
+    - pam_end() was not being called if authentication failed

+
+  * New upstream release (closes: #395507, #397961, #420035). Important
+    changes not previously backported to 4.3p2:
+    - 4.4/4.4p1 (http://www.openssh.com/txt/release-4.4):
+      + On portable OpenSSH, fix a GSSAPI authentication abort that could be
+        used to determine the validity of usernames on some platforms.
+      + Implemented conditional configuration in sshd_config(5) using the
+        "Match" directive. This allows some configuration options to be
+        selectively overridden if specific criteria (based on user, group,
+        hostname and/or address) are met. So far a useful subset of
+        post-authentication options are supported and more are expected to
+        be added in future releases.
+      + Add support for Diffie-Hellman group exchange key agreement with a
+        final hash of SHA256.
+      + Added a "ForceCommand" directive to sshd_config(5). Similar to the
+        command="..." option accepted in ~/.ssh/authorized_keys, this forces
+        the execution of the specified command regardless of what the user
+        requested. This is very useful in conjunction with the new "Match"
+        option.
+      + Add a "PermitOpen" directive to sshd_config(5). This mirrors the
+        permitopen="..." authorized_keys option, allowing fine-grained
+        control over the port-forwardings that a user is allowed to
+        establish.
+      + Add optional logging of transactions to sftp-server(8).
+      + ssh(1) will now record port numbers for hosts stored in
+        ~/.ssh/known_hosts when a non-standard port has been requested
+        (closes: #50612).
+      + Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a
+        non-zero exit code) when requested port forwardings could not be
+        established.
+      + Extend sshd_config(5) "SubSystem" declarations to allow the
+        specification of command-line arguments.
+      + Replacement of all integer overflow susceptible invocations of
+        malloc(3) and realloc(3) with overflow-checking equivalents.
+      + Many manpage fixes and improvements.
+      + Add optional support for OpenSSL hardware accelerators (engines),
+        enabled using the --with-ssl-engine configure option.
+      + Tokens in configuration files may be double-quoted in order to
+        contain spaces (closes: #319639).
+      + Move a debug() call out of a SIGCHLD handler, fixing a hang when the
+        session exits very quickly (closes: #307890).
+      + Fix some incorrect buffer allocation calculations (closes: #410599).
+      + ssh-add doesn't ask for a passphrase if key file permissions are too
+        liberal (closes: #103677).
+      + Likewise, ssh doesn't ask either (closes: #99675).
+    - 4.6/4.6p1 (http://www.openssh.com/txt/release-4.6):
+      + sshd now allows the enabling and disabling of authentication methods
+        on a per user, group, host and network basis via the Match directive
+        in sshd_config.
+      + Fixed an inconsistent check for a terminal when displaying scp
+        progress meter (closes: #257524).
+      + Fix "hang on exit" when background processes are running at the time
+        of exit on a ttyful/login session (closes: #88337).
+  * Update to current GSSAPI patch from
+    http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch;
+    install ChangeLog.gssapi.
+  * Build the .deb --with-ssl-engine (closes: #408027, LP: #119295).
+  * Use LSB functions in init scripts, and add an LSB-style header (partly
+    from Ubuntu and partly thanks to Christian Perrier; closes: #389038).
+  * Move init script start links to S16, move rc1 stop link to K84, and
+    remove rc0 and rc6 stop links altogether (the last part from Ubuntu;
+    closes: #122188).
+  * Emit a slightly more informative message from the init script if
+    /dev/null has somehow become not a character device (closes: #369964).
+  * Belatedly build-depend on zlib1g-dev (>= 1:1.2.3-1) (closes: #333447).
+  * Merge from Ubuntu:
+    - Build position-independent executables (only for debs, not for udebs)
+      to take advantage of address space layout randomisation.
+    - If building on Ubuntu, add /sbin, /usr/sbin, and /usr/local/sbin to

+  * New upstream release (closes: #361032).
+    - CVE-2006-0225: scp (as does rcp, on which it is based) invoked a
+      subshell to perform local to local, and remote to remote copy
+      operations. This subshell exposed filenames to shell expansion twice;
+      allowing a local attacker to create filenames containing shell
+      metacharacters that, if matched by a wildcard, could lead to execution
+      of attacker-specified commands with the privilege of the user running
+      scp (closes: #349645).
+    - Add support for tunneling arbitrary network packets over a connection
+      between an OpenSSH client and server via tun(4) virtual network
+      interfaces. This allows the use of OpenSSH (4.3+) to create a true VPN
+      between the client and server providing real network connectivity at
+      layer 2 or 3. This feature is experimental.
+    - Reduce default key length for new DSA keys generated by ssh-keygen
+      back to 1024 bits. DSA is not specified for longer lengths and does
+      not fully benefit from simply making keys longer. As per FIPS 186-2
+      Change Notice 1, ssh-keygen will refuse to generate a new DSA key
+      smaller or larger than 1024 bits.
+    - Fixed X forwarding failing to start when the X11 client is executed in
+      background at the time of session exit.
+    - Change ssh-keygen to generate a protocol 2 RSA key when invoked
+      without arguments (closes: #114894).

+      Kerberos authentication.
+    - Ensure that ssh always returns code 255 on internal error
+      (closes: #259865).
+    - Cleanup wtmp files on SIGTERM when not using privsep.
+    - Set SO_REUSEADDR on X11 listeners to avoid problems caused by

+      sometimes not connect to 127.0.0.1:60xx) (closes:

+    - Ensure that fds 0, 1 and 2 are always attached in all programs, by
+      duping /dev/null to them if necessary.
+    - Xauth list invocation had bogus "." argument.
+    - Remove internal assumptions on key exchange hash algorithm and output
+      length, preparing OpenSSH for KEX methods with alternate hashes.
+    - Ignore junk sent by a server before it sends the "SSH-" banner.
+    - Many manual page improvements.
+    - Lots of cleanups, including fixes to memory leaks on error paths and

+    - Add a new compression method ("Compression delayed") that delays zlib
+      compression until after authentication, eliminating the risk of zlib
+      vulnerabilities being exploited by unauthenticated users. Note that
+      users of OpenSSH versions earlier than 3.5 will need to disable
+      compression on the client or set "Compression yes" (losing this

+  * Add 'UsePAM yes' to /etc/ssh/sshd_config on upgrade from versions older
+    than this, to maintain the standard Debian sshd configuration.
+  * Comment out PAMAuthenticationViaKbdInt and RhostsAuthentication in
+    sshd_config on upgrade. Neither option is supported any more.
+  * Privilege separation and PAM are now properly supported together, so
+    remove both debconf questions related to them and simply set it
+    unconditionally in newly generated sshd_config files (closes: #228838).
+  * ServerAliveInterval implemented upstream, so ProtocolKeepAlives is now a
+    compatibility alias. The semantics differ slightly, though; see
+    ssh_config(5) for details.
+  * Implement SSH1 support for ServerAliveInterval using SSH_MSG_IGNORE. As
+    documented in ssh_config(5), it's not as good as the SSH2 version.

+  * On purge, remove only the files we know about in /etc/ssh rather than
+    the whole thing, and remove the directory if that leaves it empty
+    (closes: #176679).
+  * ssh has depended on debconf for some time now with no complaints, so:
+    - Simplify the postinst by relying on debconf being present. (The absent
+      case was buggy anyway.)
+    - Get rid of "if you have not installed debconf" text in README.Debian,
+      and generally update the "/usr/bin/ssh not SUID" entry.
+  * More README.Debian work:
+    - Reorganize into "UPGRADE ISSUES" and "OTHER ISSUES", in an effort to
+      make it easier for people to find the former. The upgrade issues
+      should probably be sorted by version somehow.
+    - Document X11UseLocalhost under "X11 Forwarding" (closes: #150913).
+  * Fix setting of IP flags for interactive sessions (upstream bug #541).

+    - As such, it should now be safe to remove --with-ipv4-default, so

+  * Point rlogin and rcp alternatives at slogin and scp respectively rather
+    than ssh (closes: #121103, #151666). Fix alternative removal to match;
+    previously it was completely wrong anyway.
+  * Find out whether /etc/ssh/sshd_not_to_be_run exists and set the debconf
+    question's default using that information, rather than using debconf as
+    a registry. Other solutions may be better in the long run, but this is
+    at least correct (thanks, Matthew Woodcraft; closes: #84725).
+  * Stop using pam_lastlog, as it doesn't currently work well as a session
+    module when privilege separation is enabled; it can usually read
+    /var/log/lastlog but can't write to it. Instead, just use sshd's
+    built-in support, already enabled by default (closes: #151297, #169938).
+  * Use 'ssh-keygen -q' rather than redirecting output to /dev/null.
+  * Add a "this may take some time" warning when creating host keys on
+    installation (part of #110094).
+  * When restarting via the init script, check for sshd_not_to_be_run after
+    stopping sshd (idea from Tomas Pospisek; closes: #149850).
+  * Append /usr/sbin:/sbin to the init script's $PATH, just in case of

+  * Warn about PermitUserEnvironment on upgrade (closes: #167895).
+  * Use 'make install-nokeys', and disable unused debhelper commands,

+  * Move the man page for gnome-ssh-askpass from the ssh package to

+      sshd_config.
+    - ssh-agent is installed setgid to prevent ptrace() attacks. The group
+      actually doesn't matter, as it drops privileges immediately, but to
+      avoid confusion the postinst creates a new 'ssh' group for it.
+  * Obsolete patches:

+      1:3.3p1-0.0woody1).
+    - Hostbased auth ssh-keysign backport (see 1:3.4p1-4).
+
+  * Remove duplicated phrase in ssh_config(5) (closes: #152404).
+  * Source the debconf confmodule at the top of the postrm rather than at

+
+OpenSSH provides end-to-end encrypted replacement of applications such as
+telnet, rlogin, and ftp.
+Unlike these legacy applications, OpenSSH never passes anything
+(including username and password) over the wire in unencrypted form, and
+provides host authentication, to verify that you really are talking to
+the system that you think you are and that no one else can take over
+that session.
+
+<p>
+The OpenSSH suite includes the 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a> 
+program which replaces rlogin and telnet, and 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a> 
+which replaces 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rcp&amp;sektion=1">rcp(1)</a> and 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ftp&amp;sektion=1">ftp(1)</a>. 
+OpenSSH has also added 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> and 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a> 
+which implement an easier solution for file-transfer. This is based upon the 
+<a href="http://www.openssh.com/txt/draft-ietf-secsh-filexfer-02.txt">secsh-filexfer</a> IETF draft.
+
+
+<p><strong>OpenSSH consists of a number of programs.</strong>
+
+<ul>
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a> - Server program run on the server machine. This listens for connections from client machines, and whenever it receives a connection, it performs authentication and starts serving the client.
+Its behaviour is controlled by the config file <i><a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
+sshd_config(5)</a></i>.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a> - This is the client program used to log into another machine or to execute commands on the other machine. <i>slogin</i> is another name for this program.
+Its behaviour is controlled by the global config file <i><a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
+ssh_config(5)</a></i> and individual users' <i>$HOME/.ssh/config</i> files.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a> - Securely copies files from one machine to another.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a> - Used to create Pubkey Authentication (RSA or DSA) keys (host keys and user authentication keys).
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-agent&amp;sektion=1">ssh-agent(1)</a> - Authentication agent.  This can be used to hold RSA keys for authentication.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-add&amp;sektion=1">ssh-add(1)</a> - Used to register new keys with the agent.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a> - SFTP server subsystem.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> - Secure file transfer program.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keyscan&amp;sektion=1">ssh-keyscan(1)</a> - gather ssh public keys.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign&amp;sektion=8">ssh-keysign(8)</a> - ssh helper program for hostbased authentication.
+</ul>
+
+<h3>Downloading</h3>
+
+<p>
+The most recent version of OpenSSH is included with the current
+distribution of <a href="http://www.openbsd.org/">OpenBSD</a>, and
+installed as part of a basic install.
+
+<p>
+Today, most other operating systems include some version of OpenSSH
+(often re-badged or privately labeled), so most users can immediately
+use it.
+However, sometimes the included versions are quite old, and missing
+features of the current release of OpenSSH, and you may wish to install
+the current version, or install it on one of the few OSs that lacked it,
+and where the OS publisher does not make a modern version available.
+You may also wish to use OpenSSH on your embedded application.
+
+<p>
+Non-OpenBSD users will want to download, compile and install the
+multi-platform <a href="http://www.openssh.com/portable.html">Portable</a> distribution from a
+<a href="http://www.openssh.com/portable.html#mirrors">mirror</a> near you.
+
+
+<h2><a name= "1.2">1.2 - Why should it be used?</a></h2>
+
+<p>
+OpenSSH is a suite of tools to help secure your network 
+connections. Here is a list of features:
+
+
+<ul>
+        <li>Strong authentication.  Closes several security holes (e.g., IP, routing, and DNS spoofing).
+        <li>Improved privacy.  All communications are automatically and transparently encrypted.
+        <li>Secure X11 sessions.  The program automatically sets DISPLAY on the server machine, and forwards any X11 connections over the secure channel.
+        <li>Arbitrary TCP/IP ports can be redirected through the encrypted channel in both directions (e.g., for e-cash transactions).
+        <li>No retraining needed for normal users.
+        <li>Never trusts the network. Minimal trust on the remote side of the connection. Minimal trust on domain name servers. Pure RSA authentication never trusts anything but the private key.
+        <li>Client RSA-authenticates the server machine in the beginning of every connection to prevent trojan horses (by routing or DNS spoofing) and man-in-the-middle attacks, and the server RSA-authenticates the client machine before accepting <i>.rhosts</i> or <i>/etc/hosts.equiv</i> authentication (to prevent DNS, routing, or IP-spoofing).
+        <li>Host authentication key distribution can be centrally by the administration, automatically when the first connection is made to a machine.
+        <li>Any user can create any number of user authentication RSA keys for his/her own use.
+        <li>The server program has its own server RSA key which is automatically regenerated every hour.
+        <li>An authentication agent, running in the user's laptop or local workstation, can be used to hold the user's RSA authentication keys.
+        <li>The software can be installed and used (with restricted functionality) even without root privileges.
+        <li>The client is customizable in system-wide and per-user configuration files.
+        <li>Optional compression of all data with gzip (including forwarded X11 and TCP/IP port data), which may result in significant speedups on slow connections.
+        <li>Complete replacement for rlogin, rsh, and rcp.
+</ul>
+
+<p>
+Currently, almost all communications in computer networks are done
+without encryption.  As a consequence, anyone who has access to any
+machine connected to the network can listen in on any communication.
+This is being done by hackers, curious administrators, employers,
+criminals, industrial spies, and governments.  Some networks leak off
+enough electromagnetic radiation that data may be captured even from a
+distance.
+
+
+<p>
+When you log in, your password goes in the network in plain
+text.  Thus, any listener can then use your account to do any evil he

+Many companies are not aware that information can so easily be

+
+<p>
+OpenSSH does not support any patented transport algorithms. In SSH1 mode,

+<h2><u><a name= "2.0">2.0 - General Questions</a></u></h2>
+
+<h2><a name= "2.1">2.1 - Why does ssh/scp make connections from low-numbered ports.</a></h2>
+<p>
+The OpenSSH client uses low numbered ports for rhosts and rhosts-rsa 
+authentication because the server needs to trust the username provided by 
+the client. To get around this, you can add the below example to your 
+<i>ssh_config</i> or <i>~/.ssh/config</i> file.
+
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+<b>UsePrivilegedPort no</b>
+                </td>
+        </tr>
+</table>
+</blockquote>
+
+<p>
+Or you can specify this option on the command line, using the <b>-o</b> 
+option to 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a> command.
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+$ <b>ssh -o "UsePrivilegedPort no" host.com</b>
+                </td>
+        </tr>
+</table>
+</blockquote>
+
+<h2><a name= "2.2">2.2 - Why is the ssh client setuid root?</a></h2>
+
+<p>
+In conjunction with the previous question, (<a href="#2.1">2.1</a>)
+OpenSSH needs root authority to be able to bind to low-numbered ports to 
+facilitate <i>rhosts authentication</i>.
+A privileged port is also required for rhosts-rsa authentication to older
+SSH releases.
+
+<p>
+Additionally, for both <i>rhosts-rsa authentication</i> (in protocol 
+version 1) and <i>hostbased authentication</i> (in protocol version 2) 
+the ssh client needs to access the <i>private host key</i> in order to 
+authenticate the client machine to the server.
+OpenSSH versions prior to 3.3 required the <code>ssh</code> binary to be
+setuid root to enable this, and you may safely remove it if you don't
+want to use these authentication methods.
+
+<p>
+Starting in OpenSSH 3.3, <code>ssh</code> is not setuid by default.  <a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign">ssh-keysign</a>,
+is used for access to the private hosts keys, and ssh does not use privileged
+source ports by default.  If you wish to use a privileged source port, you must
+manually set the setuid bit on <code>ssh</code>.
+
+<h2><a name= "2.3">2.3 - Why does SSH 2.3 have problems interoperating with OpenSSH 2.1.1?</a></h2>
+
+<p>
+SSH 2.3 and earlier versions contain a flaw in their HMAC implementation. 
+Their code was not supplying the full data block output from the digest, 
+and instead always provided 128 bits. For longer digests, this caused 
+SSH 2.3 to not interoperate with OpenSSH.
+
+<p>
+OpenSSH 2.2.0 detects that SSH 2.3 has this flaw. Recent versions of SSH 
+will have this bug fixed. Or you can add the following to 
+SSH 2.3 <i>sshd2_config</i>.
+
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">

+</table>
+</blockquote>
+
+<h2><a name= "2.4">2.4 - Why does OpenSSH print: Dispatch protocol error: type 20</a></h2>
+
+<p>
+Problems in interoperation have been seen because older versions of 
+OpenSSH did not support session rekeying. However the commercial SSH 2.3 
+tries to negotiate this feature, and you might experience connection 
+freezes or see the error message &quot;<b>Dispatch protocol error: 
+type 20 </b>&quot;. 
+To solve this problem, either upgrade to a recent OpenSSH release or 
+disable rekeying by adding the following to your commercial SSH 2.3's
+<i>ssh2_config</i> or <i>sshd2_config</i>.
+
+
+<blockquote>
+<table border=0 width="800">
+        <tr>

+<h2><a name= "2.5">2.5 - Old versions of commercial SSH encrypt host keys with IDEA.</a></h2>
+
+<p>
+The old versions of SSH used a patented algorithm to encrypt their

+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a> 
+not being able to read its host key. To solve this, use the command below

+<b>NOTE:</b> Use the 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a>

+Commercial SSH's 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a> 
+program contained a bug which caused it to occasionally generate Pubkey 
+Authentication (RSA or DSA) keys which had their Most Significant Bit 
+(MSB) unset. Such keys were advertised as being full-length, but are 
+actually, half the time, smaller than advertised.
+
+<p>
+OpenSSH will print warning messages when it encounters such keys. To rid 
+yourself of these message, edit your <i>known_hosts</i> files and replace the 
+incorrect key length (usually "1024") with the correct key length 
+(usually "1023").
+
+<h2><a name= "2.7">2.7 - X11 and/or agent forwarding does not work.</a></h2>
+
+<p>
+Check your <i>ssh_config</i> and <i>sshd_config</i>. The default 
+configuration files disable authentication agent and X11 forwarding. To 
+enable it, put the line below in <i>sshd_config</i>:
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+<b>X11Forwarding yes</b>

+<p>
+X11 forwarding requires a working <a

+>xauth(1)</a> binary.  On OpenBSD this is in the <i>xbase</i> file

+Portable, xauth must be either found at configure time or specified
+via <b>XAuthLocation</b> in sshd_config(5) and ssh_config(5).
+
+<p>
+Note on agent interoperability: There are two different and
+incompatible agent forwarding mechanisms within the SSH2 protocol.
+OpenSSH has always used an extension of the original SSH1 agent
+requests, however some commercial products use a different, non-free
+agent forwarding protocol.  This means that agent forwarding cannot
+be used between OpenSSH and those products.
+
+<p>
+<b>NOTE:</b> For users of Linux Mandrake 7.2, Mandrake modifies the

+<h2><a name= "2.9">2.9 - sftp/scp fails at connection, but ssh is OK.</a></h2>
+
+<p>
+sftp and/or scp may fail at connection time if you have shell

+for non-interactive sessions. This output confuses the sftp/scp client.  
+You can verify if your shell is doing this by executing:
+

+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">

+        </tr>
+</table>
+</blockquote>
+
+<p>
+If the above command produces any output, then you need to modify your 
+shell initialization.
+
+<h2><a name= "2.10">2.10 - Will you add [foo] to scp?</a></h2>
+
+<p>
+Short Answer: no.
+
+<p>
+Long Answer: scp is not standardized. The closest thing it has to a
+specification is "what rcp does".  Since the same command is used on both ends
+of the connection, adding features or options risks breaking interoperability with other
+implementations.
+
+<p>
+New features are more likely in sftp, since the protocol is standardized
+(well, a <a href="http://www.ietf.org/html.charters/OLD/secsh-charter.html">
+draft standard</a>), extensible, and the client and server are decoupled.
+
+<h2><a name= "2.11">2.11 - How do I use port forwarding?</a></h2>
+
+<p>
+If the remote server is running sshd(8), it may be possible to
+``tunnel'' certain services via ssh.  This may be desirable, for
+example, to encrypt POP or SMTP connections, even though the software
+does not directly support encrypted communications.  Tunnelling uses
+port forwarding to create a connection between the client and server.
+The client software must be able to specify a non-standard port to
+connect to for this to work.
+
+<p>
+The idea is that the user connects to the remote host using ssh,
+and specifies which port on the client's machine should be used to
+forward connections to the remote server.  After that it is possible
+to start the service which is to be encrypted (e.g. fetchmail, irc)
+on the client machine, specifying the same local port passed to
+ssh, and the connection will be tunnelled through ssh.  By default,
+the system running the forward will only accept connections from
+itself.
+
+<p>
+The options most relevant to tunnelling are the -L and -R options,
+which allow the user to forward connections, the -D option, which
+permits dynamic port forwarding, the -g option, which permits other
+hosts to use port forwards, and the -f option, which instructs ssh
+to put itself in the background after authentication.  See the <a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1"
+>ssh(1)</a> man page for further details.
+
+<p>
+This is an example of tunnelling an IRC session from client machine
+``127.0.0.1'' (localhost) to remote server ``server.example.com'':
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+<b>ssh -f -L 1234:server.example.com:6667 server.example.com sleep 10<br>
+irc -c '#users' -p 1234 pinky 127.0.0.1</b>
+        </td>
+        </tr>
+</table>
+</blockquote>
+
+<p>
+This tunnels a connection to IRC server server.example.com, joining
+channel ``#users'', using the nickname ``pinky''.  The local port used
+in this example is 1234.  It does not 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.
+
+<p>
+The remote command ``sleep 10'' was 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.  If more time is required, the sleep(1) value can be
+increased appropriately or, alternatively, the example above could
+be added as a function to the user's shell.  See ksh(1) and csh(1)
+for more details about user-defined functions.
+
+<p>
+ssh also has an -N option, convenient for use with port forwarding:
+if -N is specified, it is not necessary to specify a remote command
+(``sleep 10'' in the example above).  However, use of this option
+causes ssh to wait around for ever (as opposed to exiting after a
+remote command has completed), and the user must take care to manually
+kill(1) the process afterwards.
+
+<h2><a name= "2.12">2.12 - My ssh connection freezes or drops out after N minutes of inactivity.</a></h2>
+
+<p>
+This is usually the result of a packet filter or NAT device

+<b>ClientAliveInterval</b> in the server's <i><a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">

+ssh_config</a></i> (the latter is available in OpenSSH 3.8 and newer).

+<p>
+Enabling either option and setting the interval for less than the time

+<h2><a name= "2.14">2.14 - Why does OpenSSH report its version to clients?</a></h2>
+
+<p>
+OpenSSH, like most SSH implementations, reports its name and version to clients
+when they connect, e.g.
+</p>
+
+<blockquote>
+SSH-2.0-OpenSSH_3.9
+</blockquote>
+
+<p>
+This information is used by clients and servers to enable protocol 
+compatibility tweaks to work around changed, buggy or missing features in 
+the implementation they are talking to. This protocol feature checking is 
+still required at present because versions with incompatibilities are still
+in wide use.

+<h2><u><a name= "3.0">3.0 - Portable OpenSSH Questions</a></u></h2>
+
+<h2><a name= "3.1">3.1 - Spurious PAM authentication messages in logfiles.</a></h2>
+
+<p>
+The portable version of OpenSSH will generate spurious authentication 
+failures at every login, similar to:
+
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">

+                </td>
+        </tr>
+</table>
+</blockquote>
+
+<p>
+These are generated because OpenSSH first tries to determine whether a 
+user needs authentication to login (e.g. empty password). Unfortunately 
+PAM likes to log all authentication events, this one included.
+
+<p>
+If it annoys you too much, set &quot;<b>PermitEmptyPasswords no</b>&quot; 
+in <i>sshd_config</i>. This will quiet the error message at the expense 
+of disabling logins to accounts with no password set. 
+This is the default if you use the supplied <i>sshd_config</i> file.
+
+<h2><a name= "3.2">3.2 - Empty passwords not allowed with PAM authentication.</a></h2>
+
+<p>
+To enable empty passwords with a version of OpenSSH built with PAM you 
+must add the flag nullok to the end of the password checking module 
+in the <i>/etc/pam.d/sshd</i> file. For example:
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+auth required/lib/security/pam_unix.so shadow nodelay nullok
+                </td>
+        </tr>
+</table>
+</blockquote>
+
+<p>
+This must be done in addition to setting &quot;<b>PermitEmptyPasswords 
+yes</b>&quot; in the <i>sshd_config</i> file. 
+
+<p>
+There is one caveat when using empty passwords with PAM authentication: 
+PAM will allow any password when authenticating an account with an empty 
+password. This breaks the check that 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a> 
+uses to determine whether an account has no password set and grant 
+users access to the account regardless of the policy specified by 
+<b>PermitEmptyPasswords</b>. For this reason, it is recommended that you 
+do not add the <b>nullok</b> directive to your PAM configuration file 
+unless you specifically wish to allow empty passwords.

+<h3>How slow is "slow"?</h3>
+Under normal conditions, the speed of SSH logins is dependant on
+CPU speed of client and server.  For comparison the following are

+<h2><a name= "3.4">3.4 - "Can't locate module net-pf-10" messages in log under Linux.</a></h2>
+
+<p>
+The Linux kernel is looking (via modprobe) for protocol family 10 (IPv6). 
+Either load the appropriate kernel module, enter the correct alias in 
+<i>/etc/modules.conf</i> or disable IPv6 in <i>/etc/modules.conf</i>.
+
+
+<p>
+For some silly reason <i>/etc/modules.conf</i> may also be named 
+<i>/etc/conf.modules</i>.
+
+
+<h2><a name= "3.5">3.5 - Password authentication doesn't work (eg on Slackware 7.0 or Red Hat 6.x)</a></h2>
+
+<p>
+If the password is correct password the login is still denied, the
+usual cause is that the system is configured to use MD5-type passwords
+but the
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=crypt&amp;sektion=3"
+>crypt(3)</a> function used by sshd doesn't understand them.
+
+<p>
+Affected accounts will have password strings in <i>/etc/passwd</i>
+or <i>/etc/shadow</i> that start with <b>$1$</b>.
+If password authentication fails for new accounts or accounts with
+recently changed passwords, but works for old accounts, this is the
+likely culprit.
+
+<p>
+The underlying cause is that some versions of OpenSSL have a crypt(3)
+function that does not understand MD5 passwords, and the link order of
+sshd means that OpenSSL's crypt(3) is used instead of the system's.
+OpensSSH's configure attempts to correct for this but is not always
+successful.
+
+<p>
+There are several possible solutions:
+
+<ul>
+<li>
+<p>
+Enable sshd's built-in support for MD5 passwords at build time.
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+./configure --with-md5-passwords [options]
+                </td>
+        </tr>
+</table>
+</blockquote>
+
+This is safe even if you have both types of encryption as sshd will
+select the correct algorithm for each account automatically.
+
+<li>
+<p>
+If your system has a separate libcrypt library (eg Slackware 7) then you
+can manually add -lcrypt to the LIBS list so it's used instead of
+OpenSSL's:
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+LIBS=-lcrypt ./configure [options]
+                </td>
+        </tr>
+</table>
+</blockquote>
+
+<li>
+<p>
+If your platforms supports PAM, you may configure sshd to use it
+(see <a href= "#3.15" >section 3.15</a>).  This will mean that sshd will
+not verify passwords itself but will defer to the configured PAM modules.
+</ul>
+
+<h2><a name= "3.6">3.6 - Configure or sshd(8) complain about lack of RSA or DSA support</a></h2>
+
+<p>
+Ensure that your OpenSSL libraries have been built to include RSA or DSA 
+support either internally or through RSAref.
+
+
+<h2><a name= "3.7">3.7 - "scp: command not found" errors</a></h2>
+
+<p>
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a> 
+must be in the default PATH on both the client and the server. You may 
+need to use the <b>--with-default-path</b> option to specify a custom 
+path to search on the server. This option replaces the default path, 
+so you need to specify all the current directories on your path as well 
+as where you have installed scp. For example:
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+$ <b>./configure --with-default-path=/bin:/usr/bin:/usr/local/bin:/path/to/scp</b>
+                </td>
+        </tr>
+</table>
+</blockquote>
+
+<p>
+Note that configuration by the server's admin will take precedence over the
+setting of <b>--with-default-path</b>.  This includes resetting PATH in
+<i>/etc/profile</i>, PATH in <i>/etc/environment</i> on AIX, or (for 3.7p1 and
+above) setting PATH or SUPATH in <i>/etc/default/login</i> on Solaris or
+Reliant Unix.
+
+<h2><a name= "3.8">3.8 - Unable to read passphrase</a></h2>
+
+<p>
+Some operating systems set <i>/dev/tty</i> with incorrect modes, causing 
+the reading of passwords to fail with the following error:
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+You have no controlling tty.  Cannot read passphrase.
+                </td>
+        </tr>
+</table>
+</blockquote>
+
+<p>
+The solution to this is to reset the permissions on <i>/dev/tty</i> 
+to mode 0666 and report the error as a bug to your OS vendor. 
+
+
+<h2><a name= "3.9">3.9 - 'configure' missing or make fails</a></h2>
+
+<p>
+If there is no 'configure' file in the tar.gz file that you downloaded 
+or make fails with "missing separator" errors, you have probably 
+downloaded the OpenBSD distribution of OpenSSH and are attempting to 
+compile it on another platform. Please refer to the information on the 
+<a href="http://www.openssh.com/portable.html">portable version</a>.
+
+
+<h2><a name= "3.10">3.10 - Hangs when exiting ssh</a></h2>
+
+<p>
+OpenSSH may hang when exiting.  This can occur when there is an active 
+background process.  This is known to occur on Linux and HP-UX.  
+The problem can be verified by doing the following:
+
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+$ <b>sleep 20 &amp; exit</b>
+                </td>
+        </tr>
+</table>
+</blockquote>
+
+Try to use this instead:
+<blockquote>
+<table border=0 width="800">
+        <tr>
+                <td nowrap bgcolor="#EEEEEE">
+$ <b>sleep 20 &lt; /dev/null &gt; /dev/null 2&gt;&amp;1 &amp;</b>
+                </td>
+        </tr>
+</table>
+</blockquote>
+
+<p>
+A work around for bash users is to place <b>"shopt -s huponexit"</b> 
+in either /etc/bashrc  or ~/.bashrc.  Otherwise, consult your shell's 
+man page for an option to enable it to send a HUP signal to active 
+jobs when exiting.  See <a
+href="http://bugzilla.mindrot.org/show_bug.cgi?id=52">bug #52</a>
+for other workarounds.
+
+<h2><a name= "3.11">3.11 - Why does ssh hang on exit?</a></h2>
+
+<p>
+When executing
+<blockquote>
+<table border=0 width="800">

+                <td nowrap bgcolor="#EEEEEE">
+$ <b>ssh host command</b>
+                </td>
+        </tr>
+</table>
+</blockquote>
+ssh <b>needs</b> to hang, because it needs to wait:
+<ul>
+<li>
+until it can be sure that <code>command</code> does not need
+more input.
+<li>
+until it can be sure that <code>command</code> does not produce
+more output. 
+<li>
+until <code>command</code> exits because sshd needs to tell
+the exit status from <code>command</code> to ssh.
+</ul>
+<p>
+
+<h2><a name= "3.12">3.12 - I upgraded to OpenSSH 3.1 and X11
+forwarding stopped working.</a></h2>
+
+Starting with OpenSSH 3.1, the sshd x11 forwarding server listens on
+localhost by default; see the sshd <b>X11UseLocalhost</b> option to
+revert to prior behaviour if your older X11 clients do not function
+with this configuration.<p>
+
+In general, X11 clients using X11 R6 should work with the default
+setting.  Some vendors, including HP, ship X11 clients with R6
+and R5 libs, so some clients will work, and others will not work.
+This is true for HP-UX 11.X.<p>
+
+<h2><a name= "3.13">3.13 - I upgraded to OpenSSH 3.8 and some
+X11 programs stopped working.</a></h2>
+
+<p>
+As documented in the <a href="http://www.openssh.com/txt/release-3.8">3.8 release notes</a>,
+<code>ssh</code> will now use untrusted X11 cookies by 
+default.  The previous behaviour can be restored by setting
+<b>ForwardX11Trusted yes</b> in <i>ssh_config</i>.
+
+<p>
+Possible symptoms include:<br>
+<code>BadWindow (invalid Window parameter)<br>
+BadAccess (attempt to access private resource denied)<br>
+X Error of failed request:  BadAtom (invalid Atom parameter)<br>
+Major opcode of failed request:  20 (X_GetProperty)<br></code>
+
+<h2><a name= "3.14">3.14 - I copied my public key to authorized_keys
+but public-key authentication still doesn't work.</a></h2>
+
+<p>
+Typically this is caused by the file permissions on $HOME, $HOME/.ssh or
+$HOME/.ssh/authorized_keys being more permissive than sshd allows by default.
+
+<p>
+In this case, it can be solved by executing the following on the server.
+<blockquote>
+<table border=0 width="800">
+<tr>
+  <td nowrap bgcolor="#EEEEEE">
+$ <b>chmod go-w $HOME $HOME/.ssh</b><br>
+$ <b>chmod 600 $HOME/.ssh/authorized_keys</b><br>
+$ <b>chown `whoami` $HOME/.ssh/authorized_keys</b><br>
+  </td>
+</tr>
+</table>
+</blockquote>
+
+<p>
+If this is not possible for some reason, an alternative is to set
+<b>StrictModes no</b> in <i>sshd_config</i>, however this is not
+recommended.
+
+<h2><a name= "3.15">3.15 - OpenSSH versions and PAM behaviour.</a></h2>
+
+Portable OpenSSH has a configure-time option to enable sshd's use of the
+<a href="http://www.opengroup.org/onlinepubs/008329799/">PAM</a>
+(Pluggable Authentication Modules) interface.
+
+<blockquote>
+<table border=0 width="800">

+                </td>
+        </tr>
+</table>
+</blockquote>
+
+To use PAM at all, this option must be provided at build time.
+The run-time behaviour when PAM is built in varies with the version of
+Portable OpenSSH, and on later versions it must also be enabled by setting
+<b>UsePAM</b> to <b>yes</b> in <i>sshd_config</i>.
+
+<p>
+The behaviour of the relevant authentications options when PAM support is built
+in is summarised by the following table.

+<h2><a name= "3.16">3.16 - Why doesn't "w" or "who" on AIX 5.x show users

+
+Between AIX 4.3.3 and AIX 5.x, the format of the wtmp struct changed.  This
+means that sshd binaries built on AIX 4.x will not correctly write wtmp

+sshd on an AIX 5.x system and using that.

+.TH GNOME-SSH-ASKPASS 1
+.SH NAME
+gnome\-ssh\-askpass \- prompts a user for a passphrase using GNOME
+.SH SYNOPSIS
+.B gnome\-ssh\-askpass
+.SH DESCRIPTION
+.B gnome\-ssh\-askpass
+is a GNOME-based passphrase dialog for use with OpenSSH.
+It is intended to be called by the
+.BR ssh\-add (1)
+program and not invoked directly.
+It allows
+.BR ssh\-add (1)
+to obtain a passphrase from a user, even if not connected to a terminal
+(assuming that an X display is available).
+This happens automatically in the case where
+.B ssh\-add
+is invoked from one's
+.B ~/.xsession
+or as one of the GNOME startup programs, for example.
+.PP
+In order to be called automatically by
+.BR ssh\-add ,
+.B gnome\-ssh\-askpass
+should be installed as
+.IR /usr/bin/ssh\-askpass .
+.SH "ENVIRONMENT VARIABLES"
+The following environment variables are recognized:
+.TP
+.I GNOME_SSH_ASKPASS_GRAB_SERVER
+Causes
+.B gnome\-ssh\-askpass
+to grab the X server before asking for a passphrase.
+.TP
+.I GNOME_SSH_ASKPASS_GRAB_POINTER
+Causes
+.B gnome\-ssh\-askpass
+to grab the mouse pointer using
+.IR gdk_pointer_grab ()
+before asking for a passphrase.
+.PP
+Regardless of whether either of these environment variables is set,
+.B gnome\-ssh\-askpass
+will grab the keyboard using
+.IR gdk_keyboard_grab ().
+.SH AUTHOR
+This manual page was written by Colin Watson <cjwatson@debian.org>
+for the Debian system (but may be used by others).
+It was based on that for
+.B x11\-ssh\-askpass
+by Philip Hands.

+Template: openssh-server/permit-root-login
+Type: boolean
+Default: true
+_Description: Disable SSH password authentication for root?
+ Previous versions of openssh-server permitted logging in as root over SSH
+ using password authentication. The default for new installations is now
+ "PermitRootLogin prohibit-password", which disables password authentication
+ for root without breaking systems that have explicitly configured SSH
+ public key authentication for root.
+ .
+ This change makes systems more secure against brute-force password
+ dictionary attacks on the root user (a very common target for such
+ attacks). However, it may break systems that are set up with the
+ expectation of being able to SSH as root using password authentication. You
+ should only make this change if you do not need to do that.

+Subject: GSSAPI key exchange support
+
+This patch has been rejected upstream: "None of the OpenSSH developers are
+in favour of adding this, and this situation has not changed for several
+years.  This is not a slight on Simon's patch, which is of fine quality, but
+just that a) we don't trust GSSAPI implementations that much and b) we don't
+like adding new KEX since they are pre-auth attack surface.  This one is
+particularly scary, since it requires hooks out to typically root-owned
+system resources."
+
+However, quite a lot of people rely on this in Debian, and it's better to
+have it merged into the main openssh package rather than having separate
+-krb5 packages (as we used to have).  It seems to have a generally good
+security history.

+Subject: Various keepalive extensions
+
+Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported
+in previous versions of Debian's OpenSSH package but since superseded by
+ServerAliveInterval.  (We're probably stuck with this bit for
+compatibility.)
+
+In batch mode, default ServerAliveInterval to five minutes.
+
+Adjust documentation to match and to give some more advice on use of
+keepalives.

+Subject: Don't check the status field of the OpenSSL version
+
+There is no reason to check the version of OpenSSL (in Debian).  If it's
+not compatible the soname will change.  OpenSSH seems to want to do a
+check for the soname based on the version number, but wants to keep the
+status of the release the same.  Remove that check on the status since
+it doesn't tell you anything about how compatible that version is.

+Subject: Restore TCP wrappers support
+
+Support for TCP wrappers was dropped in OpenSSH 6.7.  See this message
+and thread:
+
+  https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-April/032497.html
+
+It is true that this reduces preauth attack surface in sshd.  On the
+other hand, this support seems to be quite widely used, and abruptly
+dropping it (from the perspective of users who don't read
+openssh-unix-dev) could easily cause more serious problems in practice.
+
+It's not entirely clear what the right long-term answer for Debian is,
+but it at least probably doesn't involve dropping this feature shortly
+before a freeze.

+Subject: Allow flock and ipc syscall for s390 architecture
+
+In order to use the OpenSSL-ibmpkcs11 engine it is needed to allow flock
+and ipc calls, because this engine calls OpenCryptoki (a PKCS#11
+implementation) which calls the libraries that will communicate with the
+crypto cards. OpenCryptoki makes use of flock and ipc and, as of now,
+this is only need on s390 architecture.

+
+Old versions of OpenSSH (up to 2.5 or thereabouts) allowed creating symlinks
+to ssh with the name of the host you want to connect to.  Debian ships an
+ssh-argv0 script restoring this feature; this patch refers to its manual

+These options were used as part of Debian's response to CVE-2008-0166.
+Nearly six years later, we no longer need to continue carrying the bulk
+of that patch, but we do need to avoid failing when the associated

+Subject: "LogLevel SILENT" compatibility
+
+"LogLevel SILENT" (-qq) was introduced in Debian openssh 1:3.0.1p1-1 to
+match the behaviour of non-free SSH, in which -q does not suppress fatal
+errors.  However, this was unintentionally broken in 1:4.6p1-2 and nobody
+complained, so we've dropped most of it.  The parts that remain are basic
+configuration file compatibility, and an adjustment to "Pseudo-terminal will
+not be allocated ..." which should be split out into a separate patch.

+
+Allow secure files (~/.ssh/config, ~/.ssh/authorized_keys, etc.) to be
+group-writable, provided that the group in question contains only the file's
+owner.  Rejected upstream for IMO incorrect reasons (e.g. a misunderstanding
+about the contents of gr->gr_mem).  Given that per-user groups and umask 002
+are the default setup in Debian (for good reasons - this makes operating in
+setgid directories with other groups much easier), we need to permit this by
+default.

+.Nm
+replaces the old ssh command-name as hostname handling.
+If you link to this script with a hostname then executing the link is
+equivalent to having executed ssh with that hostname as an argument.
+All other arguments are passed to ssh and will be processed normally.

+.Sh FILES
+See
+.Xr ssh 1 .
+.Sh AUTHORS
+OpenSSH is a derivative of the original and free
+ssh 1.2.12 release by Tatu Ylonen.
+Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos,
+Theo de Raadt and Dug Song
+removed many bugs, re-added newer features and
+created OpenSSH.
+Markus Friedl contributed the support for SSH
+protocol versions 1.5 and 2.0.
+Jonathan Amery wrote this ssh-argv0 script and the associated documentation.
