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

+openssh (1:3.8.1p1-9) experimental; urgency=low
+
+  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 (1:3.0.1p1-1) unstable; urgency=high
+
+  As of version 3, OpenSSH no longer uses separate files for ssh1 and ssh2
+  keys. This means the authorized_keys2 and known_hosts2 files are no longer
+  needed. They will still be read in order to maintain backward
+  compatibility.

+OpenSSH for Debian
+------------------
+
+UPGRADE ISSUES
+==============
+
+Privilege Separation
+--------------------
+
+As of 3.3, openssh has employed privilege separation to reduce the
+quantity of code that runs as root, thereby reducing the impact of
+some security holes in sshd. This now also works properly with PAM.
+
+Privilege separation is turned on by default, so, if you decide you
+want it turned off, you need to add "UsePrivilegeSeparation no" to
+/etc/ssh/sshd_config.
+
+PermitRootLogin set to yes
+--------------------------
+
+This is now the default setting (in line with upstream), and people
+who asked for an automatically-generated configuration file when
+upgrading from potato (or on a new install) will have this setting in
+their /etc/ssh/sshd_config file.
+
+Should you wish to change this setting, edit /etc/ssh/sshd_config, and
+change:
+PermitRootLogin yes
+to:
+PermitRootLogin no
+
+Having PermitRootLogin set to yes means that an attacker that knows
+the root password can ssh in directly (without having to go via a user
+account). If you set it to no, then they must compromise a normal user
+account. In the vast majority of cases, this does not give added
+security; remember that any account you su to root from is equivalent
+to root - compromising this account gives an attacker access to root
+easily. If you only ever log in as root from the physical console,
+then you probably want to set this value to no.
+
+As an aside, PermitRootLogin can also be set to "without-password" or
+"forced-commands-only" - see sshd(8) for more details.
+
+DO NOT FILE BUG REPORTS SAYING YOU THINK THIS DEFAULT IS INCORRECT!
+
+The argument above is somewhat condensed; I have had this discussion
+at great length with many people. If you think the default is
+incorrect, and feel strongly enough to want to argue about it, then
+send email to debian-ssh@lists.debian.org. I will close bug reports
+claiming the default is incorrect.
+
+SSH now uses protocol 2 by default
+----------------------------------
+
+This means all your keyfiles you used for protocol version 1 need to
+be re-generated. The server keys are done automatically, but for RSA
+authentication, please read the ssh-keygen manpage.
+
+If you have an automatically generated configuration file, and decide
+at a later stage that you do want to support protocol version 1 (not
+recommended, but note that the ssh client shipped with Debian potato
+only supported protocol version 1), then you need to do the following:
+
+Change /etc/ssh/sshd_config such that:
+Protocol 2
+becomes:
+Protocol 2,1
+Also add the line:
+HostKey /etc/ssh/ssh_host_key
+
+If you do not already have an RSA1 host key in /etc/ssh/ssh_host_key,
+you will need to generate one. To do so, run this command as root:
+
+  ssh-keygen -f /etc/ssh/ssh_host_key -N '' -t rsa1
+
+As of openssh-server 1:4.1p1-2, the option to support protocol version 1
+is no longer available via debconf. You must edit the configuration file
+instead.
+
+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
+============
+
+/usr/bin/ssh not SUID
+---------------------
+
+Due to Debian bug #164325, RhostsRSAAuthentication can only be used if ssh
+is SUID.  Until this is fixed, if that is a problem, use:
+
+   dpkg-statoverride
+
+or if that's also missing, use this:
+
+   chown root.root /usr/bin/ssh
+   chmod 04755 /usr/bin/ssh
+
+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 Kerberos support for SSH protocol 1 and
+parts of the 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 ('/etc/init.d/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 ('rm -f /etc/rc[2345].d/S16ssh') and that you will need to
+restart this sshd manually on upgrades.

+The following instructions relate to CVE-2008-0166. They were prepared by
+Matt Zimmerman, assisted by Colin Watson.
+
+== What Happened ==
+
+A weakness has been discovered in the random number generator used by OpenSSL
+on Debian and Ubuntu systems.  As a result of this weakness, certain encryption
+keys are much more common than they should be, such that an attacker could
+guess the key through a brute-force attack given minimal knowledge of the
+system.  This particularly affects the use of encryption keys in OpenSSH,
+OpenVPN and SSL certificates.
+
+This vulnerability only affects operating systems which (like Ubuntu) are based
+on Debian.  However, other systems can be indirectly affected if weak keys are
+imported into them.
+
+We consider this an extremely serious vulnerability, and urge all users to act
+immediately to secure their systems.
+
+== Who is affected ==
+
+Systems which are running any of the following releases:
+
+ * Debian 4.0 (etch)
+ * Ubuntu 7.04 (Feisty)
+ * Ubuntu 7.10 (Gutsy)
+ * Ubuntu 8.04 LTS (Hardy)
+ * Ubuntu "Intrepid Ibex" (development): libssl <= 0.9.8g-8
+
+and have openssh-server installed or have been used to create an OpenSSH key or
+X.509 (SSL) certificate.
+
+All OpenSSH and X.509 keys generated on such systems must be considered
+untrustworthy, regardless of the system on which they are used, even after the
+update has been applied.
+
+This includes the automatically generated host keys used by OpenSSH, which are
+the basis for its server spoofing and man-in-the-middle protection.
+
+The specific package versions affected are:
+
+ * Debian 4.0: libssl <= 0.9.8c-4etch3
+ * Ubuntu 7.04: libssl <= 0.9.8c-4ubuntu0.2
+ * Ubuntu 7.10: libssl <= 0.9.8e-5ubuntu3.1
+ * Ubuntu 8.04: libssl <= 0.9.8g-4ubuntu3
+
+== What to do if you are affected ==
+
+OpenSSH:
+
+1. Install the security updates
+
+   Once the update is applied, weak user keys will be automatically rejected
+   where possible (though they cannot be detected in all cases).  If you are
+   using such keys for user authentication, they will immediately stop working
+   and will need to be replaced (see step 3).
+   
+   OpenSSH host keys can be automatically regenerated when the OpenSSH security
+   update is applied.  The update will prompt for confirmation before taking
+   this step.
+   
+2. Update OpenSSH known_hosts files
+
+   The regeneration of host keys will cause a warning to be displayed when
+   connecting to the system using SSH until the host key is updated in the
+   known_hosts file.  The warning will look like this:
+
+   @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
+   @    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
+   @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
+   IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
+   Someone could be eavesdropping on you right now (man-in-the-middle attack)!
+   It is also possible that the RSA host key has just been changed.
+
+   In this case, the host key has simply been changed, and you should update
+   the relevant known_hosts file as indicated in the error message.
+
+3. Check all OpenSSH user keys
+
+   The safest course of action is to regenerate all OpenSSH user keys,
+   except where it can be established to a high degree of certainty that the
+   key was generated on an unaffected system.
+
+   Check whether your key is affected by running the ssh-vulnkey tool, included
+   in the security update.  By default, ssh-vulnkey will check the standard
+   location for user keys (~/.ssh/id_rsa, ~/.ssh/id_dsa and ~/.ssh/identity),
+   your authorized_keys file (~/.ssh/authorized_keys and
+   ~/.ssh/authorized_keys2), and the system's host keys
+   (/etc/ssh/ssh_host_dsa_key and /etc/ssh/ssh_host_rsa_key).
+
+   To check all your own keys, assuming they are in the standard
+   locations (~/.ssh/id_rsa, ~/.ssh/id_dsa, or ~/.ssh/identity):
+
+     ssh-vulnkey
+
+   To check all keys on your system:
+
+     sudo ssh-vulnkey -a
+
+   To check a key in a non-standard location:
+
+     ssh-vulnkey /path/to/key
+
+   If ssh-vulnkey says "Unknown (no blacklist information)", then it has no
+   information about whether that key is affected.  If in doubt, destroy the
+   key and generate a new one.
+
+4. Regenerate any affected user keys
+
+   OpenSSH keys used for user authentication must be manually regenerated,
+   including those which may have since been transferred to a different system
+   after being generated.
+
+   New keys can be generated using ssh-keygen, e.g.:
+
+   $ ssh-keygen 
+   Generating public/private rsa key pair.
+   Enter file in which to save the key (/home/user/.ssh/id_rsa): 
+   Enter passphrase (empty for no passphrase): 
+   Enter same passphrase again: 
+   Your identification has been saved in /home/user/.ssh/id_rsa.
+   Your public key has been saved in /home/user/.ssh/id_rsa.pub.
+   The key fingerprint is:
+   00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 user@host
+
+5. Update authorized_keys files (if necessary)
+
+   Once the user keys have been regenerated, the relevant public keys must
+   be propagated to any authorized_keys files on remote systems.  Be sure to
+   delete the affected key.
+
+OpenSSL:
+
+1. Install the security update
+
+2. Create new certificates to replace any server or client certificates in use
+   on the system
+
+3. If certificates have been generated for use on other systems, they must be
+   found and replaced as well.
+
+== Removing openssh-blacklist ==
+
+For the moment, the openssh-server package depends on openssh-blacklist, in
+order that the blacklist is deployed to the maximum possible number of
+systems to reduce the potential spread of worms exploiting this
+vulnerability. We acknowledge that this may be inconvenient for some small
+systems, but nevertheless feel that this was the best course of action.
+
+If you absolutely need to remove the blacklist from your system, then you
+can run the following commands to substitute a fake package for
+openssh-blacklist:
+
+  sudo apt-get install equivs
+  equivs-control openssh-blacklist.ctl
+  sed -i 's/^Package:.*/Package: openssh-blacklist/' openssh-blacklist.ctl
+  sed -i 's/^# Version:.*/Version: 9:1.0/' openssh-blacklist.ctl
+  equivs-build openssh-blacklist.ctl
+  sudo dpkg -i openssh-blacklist_1.0_all.deb
+
+Be warned: this circumvents a security measure for the sake of disk space.
+You should only do this if you have no other option, and if you are certain
+that no compromised keys will ever be generated on or copied onto this
+system.
+
+Once a sufficient amount of time and number of releases have passed, the
+openssh-blacklist package will be phased out.

+
+  * Change start condition of Upstart job to be just the standard "runlevel
+    [2345]", rather than "filesystem or runlevel [2345]"; the latter makes
+    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
+    truly ghastly hack around a misbehaviour in sarge's dpkg.  Since this is
+    now four Debian releases ago, we can afford to drop this and simplify
+    the packaging.
+  * Remove ssh/use_old_init_script, which was a workaround for a very old
+    bug in /etc/init.d/ssh.  If anyone has ignored this for >10 years then
+    they aren't going to be convinced now (closes: #214182).
+  * Remove support for upgrading directly from ssh-nonfree.
+  * Remove lots of maintainer script support for direct upgrades from

+    openssh-server.postinst.
+  * Replace old manual conffile handling code with dpkg-maintscript-helper,
+    via dh_installdeb.
+  * 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.

+      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).

+      temporary directories (closes: #357469, although only if you arrange

+
+  * 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.

+  * Backport from upstream:

+      re-execs itself.  Prevents two HUPs in quick succession from resulting
+      in sshd dying (LP: #497781).
+    - Output a debug if we can't open an existing keyfile (LP: #505301).
+  * Use host compiler for ssh-askpass-gnome when cross-compiling.
+  * Don't run tests when cross-compiling.
+  * Drop change from 1:3.6.1p2-5 to disable cmsg_type check for file
+    descriptor passing when running on Linux 2.0.  The previous stable

+    - Change the default cipher order to prefer the AES CTR modes and the
+      revised "arcfour256" mode to CBC mode ciphers that are susceptible to
+      CPNI-957037 "Plaintext Recovery Attack Against SSH".
+    - Add countermeasures to mitigate CPNI-957037-style attacks against the
+      SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid
+      packet length or Message Authentication Code, ssh/sshd will continue
+      reading up to the maximum supported packet length rather than
+      immediately terminating the connection. This eliminates most of the
+      known differences in behaviour that leaked information about the

+      (closes: #506115, LP: #379329).

+    - Add AllowAgentForwarding to available Match keywords list (closes:
+      #540623).
+    - Make ssh(1) send the correct channel number for
+      SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to
+      avoid triggering 'Non-public channel' error messages on sshd(8) in
+      openssh-5.1.
+    - Avoid printing 'Non-public channel' warnings in sshd(8), since the

+      behaviour introduced in openssh-5.1; closes: #496017).

+
+  * 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.

+      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.

+      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.org/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.org/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
+      the default path.
+  * Use ${binary:Version} rather than ${Source-Version} in openssh-server ->
+    openssh-client dependency.

+  * It turns out that the people who told me that removing a conffile in the

+
+  * 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).
+    - Fix timing variance for valid vs. invalid accounts when attempting
+      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

+
+  * New upstream release.
+    - SECURITY (CAN-2005-2797): Fix a bug introduced in OpenSSH 4.0 that
+      caused GatewayPorts to be incorrectly activated for dynamic ("-D")
+      port forwardings when no listen address was explicitly specified
+      (closes: #326065).
+    - SECURITY (CAN-2005-2798): Fix improper delegation of GSSAPI
+      credentials. This code is only built in openssh-krb5, not openssh, but
+      I mention the CVE reference here anyway for completeness.
+    - 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
+      security benefit) on the server.
+    - Increase the default size of new RSA/DSA keys generated by ssh-keygen
+      from 1024 to 2048 bits (closes: #181162).
+    - Many bugfixes and improvements to connection multiplexing.
+    - Don't pretend to accept $HOME (closes: #208648).
+  * debian/rules: Resynchronise CFLAGS with that generated by configure.
+  * openssh-client and openssh-server conflict with pre-split ssh to avoid
+    problems when ssh is left un-upgraded (closes: #324695).
+  * Set X11Forwarding to yes in the default sshd_config (new installs only).
+    At least when X11UseLocalhost is turned on, which is the default, the
+    security risks of using X11 forwarding are risks to the client, not to
+    the server (closes: #320104).

+
+  * openssh-client and openssh-server conflict with ssh-krb5, as ssh-krb5
+    only conflicts with ssh (closes: #312475).
+  * SELinux support (thanks, Manoj Srivastava; closes: #308555):
+    - Added SELinux capability, and turned it on be default. Added
+      restorecon calls in preinst and postinst (should not matter if the
+      machine is not SELinux aware). By and large, the changes made should
+      have no effect unless the rules file calls --with-selinux; and even
+      then there should be no performance hit for machines not actively
+      running SELinux.
+    - Modified the preinst and postinst to call restorecon to set the
+      security context for the generated public key files.
+    - Added a comment to /etc/pam.d/ssh to indicate that an SELinux system
+      may want to also include pam_selinux.so.
+  * Re-enable ssh-askpass-gnome on the Hurd, now that its build-dependencies
+    are available.

+    and has not been the default since openssh 1:3.0.1p1-1. Users who need
+    this should edit sshd_config instead (closes: #147212).
+  * Since ssh-keysign isn't used by default (you need to set
+    EnableSSHKeysign to "yes" in /etc/ssh/ssh_config), having a debconf
+    question to ask whether it should be setuid is overkill, and the

+    ssh-keysign setuid in openssh-client.deb, and set a statoverride if the

+    Use PAM password authentication to avoid #278394. In future I may
+    provide two sets of binaries built with and without this option, since
+    it seems I can't win.
+  * Disable ChallengeResponseAuthentication in new installations, returning
+    to PasswordAuthentication by default, since it now supports PAM and
+    apparently works better with a non-threaded sshd (closes: #247521).
+  * openssh-server Suggests: rssh (closes: #233012).
+  * Change libexecdir to /usr/lib/openssh, and fix up various alternatives

+
+  * New upstream release.
+    - Port-forwarding specifications now take optional bind addresses, and
+      the server allows client-specified bind addresses for remote port
+      forwardings when configured with "GatewayPorts clientspecified"
+      (closes: #87253, #192206).
+    - ssh and ssh-keyscan now support hashing of known_hosts files for
+      improved privacy (CAN-2005-2666). ssh-keygen has new options for
+      managing known_hosts files, which understand hashing.
+    - sftp supports command history and editing support using libedit
+      (closes: #287013).
+    - Have scp and sftp wait for the spawned ssh to exit before they exit
+      themselves, allowing ssh to restore terminal modes (closes: #257130).
+    - Improved the handling of bad data in authorized_keys files,
+      eliminating fatal errors on corrupt or very large keys; e.g. linefeeds
+      in keys only produce errors in auth.log now (closes: #220726).
+    - Add "command mode" to ssh connection multiplexing (closes: #303452).
+    - Mention $HOME/.hushlogin in sshd(8) FILES section (closes: #163933).
+  * Make gnome-ssh-askpass stay above other windows (thanks, Liyang HU;
+    closes: #296487).
+  * Remove obsolete and unnecessary ssh/forward_warning debconf note.
+  * Hurd build fixes (although sshd still doesn't work):
+    - Restore X forwarding fix from #102991, lost somewhere along the way.
+    - Link with -lcrypt.
+    - Link with -lpthread rather than -pthread.
+    - Don't build ssh-askpass-gnome on the Hurd, until GNOME is available to
+      satisfy build-dependencies.
+  * Drop workaround for #242462 on amd64; it's been fixed properly upstream.
+  * Enable HashKnownHosts by default. This only affects new entries; use
+    'ssh-keygen -H' to convert an entire known_hosts file to hashed format.
+  * Note in ssh_config(5) that the SetupTimeOut option is Debian-specific
+    (closes: #307069).

+  * New upstream release (closes: #232281):
+    - New PAM implementation based on that in FreeBSD. This runs PAM session
+      modules before dropping privileges (closes: #132681, #150968).
+    - Since PAM session modules are run as root, we can turn pam_limits back
+      on by default, and it no longer spits out "Operation not permitted" to
+      syslog (closes: #171673).
+    - Password expiry works again (closes: #153235).
+    - 'ssh -q' suppresses login banner (closes: #134589).
+    - sshd doesn't lie to PAM about invalid usernames (closes: #157078).
+    - ssh-add prints key comment on each prompt (closes: #181869).
+    - Punctuation formatting fixed in man pages (closes: #191131).
+    - EnableSSHKeysign documented in ssh_config(5) (closes: #224457).
+  * 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.
+  * Remove -fno-builtin-log, -DHAVE_MMAP_ANON_SHARED, and

+  * Update config.guess and config.sub from autotools-dev 20040105.1.

+
+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.org/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.org/portable.html">Portable</a> distribution from a
+<a href="http://www.openssh.org/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.

+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
+likes.  Many incidents have been encountered worldwide where crackers
+have started programs on workstations without the owner's knowledge
+just to listen to the network and collect passwords.  Programs for
+doing this are available on the Internet, or can be built by a
+competent programmer in a few hours.
+
+
+<p>
+Businesses have trade secrets, patent applications in preparation,
+pricing information, subcontractor information, client data, personnel
+data, financial information, etc.  Currently, anyone with access to
+the network (any machine on the network) can listen to anything that
+goes in the network, without any regard to normal access restrictions.
+
+
+<p>
+Many companies are not aware that information can so easily be
+recovered from the network.  They trust that their data is safe
+since nobody is supposed to know that there is sensitive information
+in the network, or because so much other data is transferred in the
+network.  This is not a safe policy.

+
+<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.

+<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:
+

+        <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.

+moduli that were just smaller than what sshd would look for, and
+as a result, sshd would end up using moduli significantly larger
+than requested, which resulted in a speed penalty.  Replacing the
+<i>moduli</i> file will resolve this (note that in most cases this
+file will not be replaced during an upgrade and must be replaced
+manually).</li>
+
+<li>OpenSSH releases prior to 3.8 had a flaw in <code>ssh</code> that
+would cause it to request moduli larger than intended (which when
+combined with the above resulted in significant slowdowns).
+Upgrading the client to 3.8 or higher will resolve this issue.</li>
+
+<li>If either the client or server lack a kernel-based random number
+device (eg Solaris &lt; 9, AIX &lt; 5.2, HP-UX &lt; 11.11) and no
+substitute is available (eg <a href=
+"ftp://ftp.ayamura.org/pub/prngd/">prngd</a>) it's possible that
+one of the programs called by <code>ssh-rand-helper</code> to
+generate entropy is hanging.  This can be investigated by running
+it in debug mode:
+
+<blockquote>
+<table border=0 width="800">

+                </td>
+        </tr>

+
+Any significant delays should be investigated and rectified, or the
+corresponding commands should be removed from <i>ssh_prng_cmds</i>.

+
+</ul>
+
+<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
+typical connect times for <code>time ssh localhost true</code>

+OpenSSL were compiled with gcc 3.3.x.

+<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>.
+
+

+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

+
+<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.org/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>
+

+                </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

+
+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.org/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 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>

+        </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>.
+

+.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.

+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

+
+In batch mode, default ServerAliveInterval to five minutes.

+
+This makes it easier to audit networks for versions patched against security
+vulnerabilities.  It has little detrimental effect, as attackers will
+generally just try attacks rather than bothering to scan for
+vulnerable-looking version strings.  (However, see debian-banner.patch.)

+Subject: Reduce severity of "Killed by signal %d"
+
+This produces irritating messages when using ProxyCommand or other programs
+that use ssh under the covers (e.g. Subversion).  These messages are more
+normally printed by the calling program, such as the shell.
+
+According to the upstream bug, the right way to avoid this is to use the -q
+option, so we may drop this patch after further investigation into whether
+any software in Debian is still relying on it.

+
+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

+Subject: Reject vulnerable keys to mitigate Debian OpenSSL flaw
+
+In 2008, Debian (and derived distributions such as Ubuntu) shipped an
+OpenSSL package with a flawed random number generator, causing OpenSSH to
+generate only a very limited set of keys which were subject to private half
+precomputation.  To mitigate this, this patch checks key authentications
+against a blacklist of known-vulnerable keys, and adds a new ssh-vulnkey
+program which can be used to explicitly check keys against that blacklist.
+See CVE-2008-0166.

++.Sh DESCRIPTION
++.Nm
++checks a key against a blacklist of compromised keys.
++.Pp
++A substantial number of keys are known to have been generated using a broken
++version of OpenSSL distributed by Debian which failed to seed its random
++number generator correctly.
++Keys generated using these OpenSSL versions should be assumed to be
++compromised.
++This tool may be useful in checking for such keys.
++.Pp
++Keys that are compromised cannot be repaired; replacements must be generated
++using
++.Xr ssh-keygen 1 .

++The argument list will be interpreted as a list of paths to public key files
++or
++.Pa authorized_keys
++files.
++If no suitable file is found at a given path,

++and retry, in case it was given a private key file.
++If no files are given as arguments,

++/home/user/.ssh/authorized_keys:3: Unknown (blacklist file not installed): RSA 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx user@host
++.Ed
++.Pp
++Each line is of the following format (any lines beginning with
++.Dq #
++should be ignored by scripts):
++.Pp
++.Dl Ar filename : Ns Ar line : Ar status : Ar type Ar size Ar fingerprint Ar comment
++.Pp
++It is important to distinguish between the possible values of
++.Ar status :
++.Pp
++.Bl -tag -width Ds
++.It COMPROMISED
++These keys are listed in a blacklist file, normally because their
++corresponding private keys are well-known.
++Replacements must be generated using
++.Xr ssh-keygen 1 .
++.It Not blacklisted
++A blacklist file exists for this key type and size, but this key is not
++listed in it.
++Unless there is some particular reason to believe otherwise, this key
++may be used safely.
++(Note that DSA keys used with the broken version of OpenSSL distributed
++by Debian may be compromised in the event that anyone captured a network
++trace, even if they were generated with a secure version of OpenSSL.)
++.It Unknown (blacklist file not installed)
++No blacklist file exists for this key type and size.
++You should find a suitable published blacklist and install it before
++deciding whether this key is safe to use.
++.El
++.Pp
++The options are as follows:
++.Bl -tag -width Ds
++.It Fl a
++Check keys of all users on the system.
++You will typically need to run
++.Nm
++as root to use this option.
++For each user,
++.Nm
++will check
++.Pa ~/.ssh/id_rsa ,
++.Pa ~/.ssh/id_dsa ,
++.Pa ~/.ssh/identity ,
++.Pa ~/.ssh/authorized_keys
++and
++.Pa ~/.ssh/authorized_keys2 .
++It will also check the system's host keys.
++.It Fl q
++Quiet mode.
++Normally,
++.Nm
++outputs the fingerprint of each key scanned, with a description of its
++status.
++This option suppresses that output.
++.It Fl v
++Verbose mode.
++Normally,
++.Nm
++does not output anything for keys that are not listed in their corresponding
++blacklist file (although it still produces output for keys for which there
++is no blacklist file, since their status is unknown).
++This option causes
++.Nm
++to produce output for all keys.
++.El
++.Sh EXIT STATUS
++.Nm
++will exit zero if any of the given keys were in the compromised list,
++otherwise non-zero.
++.Sh BLACKLIST FILE FORMAT
++The blacklist file may start with comments, on lines starting with
++.Dq # .
++After these initial comments, it must follow a strict format:
++.Pp
++.Bl -bullet -offset indent -compact
++.It
++All the lines must be exactly the same length (20 characters followed by a
++newline) and must be in sorted order.
++.It
++Each line must consist of the lower-case hexadecimal MD5 key fingerprint,
++without colons, and with the first 12 characters removed (that is, the least
++significant 80 bits of the fingerprint).
++.El
++.Pp
++The key fingerprint may be generated using
++.Xr ssh-keygen 1 :
++.Pp
++.Dl $ ssh-keygen -l -f /path/to/key
++.Pp
++This strict format is necessary to allow the blacklist file to be checked
++quickly, using a binary-search algorithm.
++.Sh FILES
++.Bl -tag -width Ds
++.It Pa ~/.ssh/id_rsa
++If present, contains the protocol version 2 RSA authentication identity of
++the user.
++.It Pa ~/.ssh/id_dsa
++If present, contains the protocol version 2 DSA authentication identity of
++the user.
++.It Pa ~/.ssh/identity
++If present, contains the protocol version 1 RSA authentication identity of

++If present, lists the public keys (RSA/DSA) that can be used for logging in
++as this user.
++.It Pa ~/.ssh/authorized_keys2
++Obsolete name for
++.Pa ~/.ssh/authorized_keys .
++This file may still be present on some old systems, but should not be
++created if it is missing.
++.It Pa /etc/ssh/ssh_host_rsa_key
++If present, contains the protocol version 2 RSA identity of the system.

++If present, lists the blacklisted keys of type
++.Ar TYPE

++The format of this file is described above.
++RSA1 keys are converted to RSA before being checked in the blacklist.
++Note that the fingerprints of RSA1 keys are computed differently, so you
++will not be able to find them in the blacklist by hand.

+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.

+Subject: Allow harmless group-writability
+
+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.

+It is split out from the main package to isolate the dependency on the
+Gnome and X11 libraries.

+ssh-krb5 (1:4.3p2-7) unstable; urgency=low
+
+  The normal openssh-server and openssh-client packages in Debian now
+  include full GSSAPI support, including key exchange.  This package is
+  now only a transitional package that depends on openssh-server and
+  openssh-client and configures openssh-server for GSSAPI authentication
+  if it wasn't already.
+
+  You can now simply install openssh-server and openssh-client directly
+  and remove this package.  Just make sure that /etc/ssh/sshd_config
+  contains:
+
+    GSSAPIAuthentication yes
+    GSSAPIKeyExchange yes
+
+  if you want to support GSSAPI authentication to your ssh server.
