3 OpenSSH 7.2 disables a number of legacy cryptographic algorithms by
4 default in ssh:
5
6 * Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and the
7 rijndael-cbc aliases for AES.
8 * MD5-based and truncated HMAC algorithms.
9
10 These algorithms are already disabled by default in sshd.

14openssh (1:7.1p1-2) unstable; urgency=medium
15
16 OpenSSH 7.0 disables several pieces of weak, legacy, and/or unsafe
17 cryptography.
18
19 * Support for the legacy SSH version 1 protocol is disabled by default at
20 compile time. Note that this also means that the Cipher keyword in
21 ssh_config(5) is effectively no longer usable; use Ciphers instead for
22 protocol 2. The openssh-client-ssh1 package includes "ssh1", "scp1",
23 and "ssh-keygen1" binaries which you can use if you have no alternative
24 way to connect to an outdated SSH1-only server; please contact the
25 server administrator or system vendor in such cases and ask them to
26 upgrade.
27 * Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is
28 disabled by default at run-time. It may be re-enabled using the
29 instructions at http://www.openssh.com/legacy.html
30 * Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by
31 default at run-time. These may be re-enabled using the instructions at
32 http://www.openssh.com/legacy.html
33 * Support for the legacy v00 cert format has been removed.
34
35 Future releases will retire more legacy cryptography, including:
36
37 * Refusing all RSA keys smaller than 1024 bits (the current minimum is
38 768 bits).
39 * Several ciphers will be disabled by default: blowfish-cbc, cast128-cbc,
40 all arcfour variants, and the rijndael-cbc aliases for AES.
41 * MD5-based HMAC algorithms will be disabled by default.

45openssh (1:6.7p1-5) unstable; urgency=medium
46
47 openssh-server 1:6.7p1-4 changed the default setting of AcceptEnv to list
48 a number of specific LC_FOO variables rather than the wildcard LC_*. I
49 have since been persuaded that this was a bad idea and have reverted it,
50 but it is difficult to automatically undo the change to
51 /etc/ssh/sshd_config without compounding the problem (that of modifying
52 configuration that some users did not want to be modified) further. Most
53 users who upgraded via version 1:6.7p1-4 should restore the previous value
54 of "AcceptEnv LANG LC_*" in /etc/ssh/sshd_config.

60 Smartcard support is now available using PKCS#11 tokens. If you were
61 previously using an unofficial build of Debian's OpenSSH package with
62 OpenSC-based smartcard support added, then note that commands like
63 'ssh-add -s 0' will no longer work; you need to use 'ssh-add -s
64 /usr/lib/opensc-pkcs11.so' instead.

69
70 The ssh package has been split into openssh-client and openssh-server. If
71 you had previously requested that the sshd server should not be run, then
72 that request will still be honoured. However, the recommended approach is
73 now to remove the openssh-server package if you do not want to run sshd.
74 You can remove the old /etc/ssh/sshd_not_to_be_run marker file after doing
75 that.

79openssh (1:3.5p1-1) unstable; urgency=low
80
81 This version of OpenSSH disables the environment option for public keys by
82 default, in order to avoid certain attacks (for example, LD_PRELOAD). If
83 you are using this option in an authorized_keys file, beware that the keys
84 in question will no longer work until the option is removed.
85
86 To re-enable this option, set "PermitUserEnvironment yes" in
87 /etc/ssh/sshd_config after the upgrade is complete, taking note of the
88 warning in the sshd_config(5) manual page.

93
94 As of version 3, OpenSSH no longer uses separate files for ssh1 and ssh2
95 keys. This means the authorized_keys2 and known_hosts2 files are no longer
96 needed. They will still be read in order to maintain backward
97 compatibility.

1OpenSSH for Debian
2------------------
3
4UPGRADE ISSUES
5==============
6
7Privilege Separation
8--------------------
9
10As of 3.3, openssh has employed privilege separation to reduce the
11quantity of code that runs as root, thereby reducing the impact of
12some security holes in sshd. This now also works properly with PAM.
13
14Privilege separation is turned on by default, so, if you decide you
15want it turned off, you need to add "UsePrivilegeSeparation no" to
16/etc/ssh/sshd_config.
17
18PermitRootLogin
19---------------
20
21As of 1:6.6p1-1, new installations will be set to "PermitRootLogin
22without-password" (or the synonymous "PermitRootLogin prohibit-password" as
23of 1:7.1p1-1). This disables password authentication for root, foiling
24password dictionary attacks on the root user. Some sites may wish to use
25the stronger "PermitRootLogin forced-commands-only" or "PermitRootLogin no",
26but note that "PermitRootLogin no" will break setups that SSH to root with a
27forced command to take full-system backups. You can use PermitRootLogin in
28a Match block if you want finer-grained control here.
29
30For many years Debian's OpenSSH packaging used "PermitRootLogin yes", in
31line with upstream. To avoid breaking local setups, this is still true for
32installations upgraded from before 1:6.6p1-1. If you wish to change this,
33you should edit /etc/ssh/sshd_config, change it manually, and run "service
34ssh restart" as root.
35
36Disabling PermitRootLogin means that an attacker possessing credentials for
37the root account (any credentials in the case of "yes", or private key
38material in the case of "prohibit-password") must compromise a normal user
39account rather than being able to SSH directly to root. Be careful to avoid
40a false illusion of security if you change this setting; any account you
41escalate to root from should be considered equivalent to root for the
42purposes of security against external attack. You might for example disable
43it if you know you will only ever log in as root from the physical console.
44
45Since the root account does not generally have non-password credentials
46unless you explicitly install an SSH public key in its
47~/.ssh/authorized_keys, which you presumably only do if you want to SSH to
48it, "prohibit-password" should be a reasonable default for most sites.
49
50As of OpenSSH 7.0, this is the upstream default.
51

56
57X11 Forwarding
58--------------
59
60ssh's default for ForwardX11 has been changed to ``no'' because it has
61been pointed out that logging into remote systems administered by
62untrusted people is likely to open you up to X11 attacks, so you
63should have to actively decide that you trust the remote machine's
64root, before enabling X11. I strongly recommend that you do this on a
65machine-by-machine basis, rather than just enabling it in the default
66host settings.
67
68In order for X11 forwarding to work, you need to install xauth on the
69server. In Debian this is in the xbase-clients package.
70
71As of OpenSSH 3.1, the remote $DISPLAY uses localhost by default to reduce
72the security risks of X11 forwarding. Look up X11UseLocalhost in
73sshd_config(8) if this is a problem.
74
75OpenSSH 3.8 invented ForwardX11Trusted, which when set to no causes the
76ssh client to create an untrusted X cookie so that attacks on the
77forwarded X11 connection can't become attacks on X clients on the remote
78machine. However, this has some problems in implementation - notably a
79very short timeout of the untrusted cookie - breaks large numbers of
80existing setups, and generally seems immature. The Debian package
81therefore sets the default for this option to "yes" (in ssh itself,
82rather than in ssh_config).
83
84Fallback to RSH
85---------------
86
87The default for this setting has been changed from Yes to No, for
88security reasons, and to stop the delay attempting to rsh to machines
89that don't offer the service. Simply switch it back on in either
90/etc/ssh/ssh_config or ~/.ssh/config for those machines that you need
91it for.
92
93Setgid ssh-agent and environment variables
94------------------------------------------
95
96As of version 1:3.5p1-1, ssh-agent is installed setgid to prevent ptrace()
97attacks retrieving private key material. This has the side-effect of causing
98glibc to remove certain environment variables which might have security
99implications for set-id programs, including LD_PRELOAD, LD_LIBRARY_PATH, and
100TMPDIR.
101
102If you need to set any of these environment variables, you will need to do
103so in the program exec()ed by ssh-agent. This may involve creating a small
104wrapper script.
105
106Symlink Hostname invocation
107---------------------------
108
109This version of ssh no longer includes support for invoking ssh with the
110hostname as the name of the file run. People wanting this support should
111use the ssh-argv0 script.
112
113=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
114
115OTHER ISSUES
116============
117
118/usr/bin/ssh not SUID
119---------------------
120
121Due to Debian bug #164325, RhostsRSAAuthentication can only be used if ssh
122is SUID. Until this is fixed, if that is a problem, use:
123
124 dpkg-statoverride
125
126or if that's also missing, use this:
127
128 chown root.root /usr/bin/ssh
129 chmod 04755 /usr/bin/ssh
130
131Authorization Forwarding
132------------------------
133
134Similarly, root on a remote server could make use of your ssh-agent
135(while you're logged into their machine) to obtain access to machines
136which trust your keys. This feature is therefore disabled by default.
137You should only re-enable it for those hosts (in your ~/.ssh/config or
138/etc/ssh/ssh_config) where you are confident that the remote machine
139is not a threat.
140
141Problems logging in with RSA authentication
142-------------------------------------------
143
144If you have trouble logging in with RSA authentication then the
145problem is probably caused by the fact that you have your home
146directory writable by group, as well as user (this is the default on
147Debian systems).
148
149Depending upon other settings on your system (i.e. other users being
150in your group) this could open a security hole, so you will need to
151make your home directory writable only by yourself. Run this command,
152as yourself:
153
154 chmod g-w ~/
155
156to remove group write permissions. If you use ssh-copy-id to install your
157keys, it does this for you.
158
159-L option of ssh nonfree
160------------------------
161
162non-free ssh supported the usage of the option -L to use a non privileged
163port for scp. This option will not be supported by scp from openssh.
164
165Please use instead scp -o "UsePrivilegedPort=no" as documented in the
166manpage to scp itself.
167
168Problem logging in because of TCP-Wrappers
169------------------------------------------
170
171ssh is compiled with support for tcp-wrappers. So if you can no longer
172log into your system, please check that /etc/hosts.allow and /etc/hosts.deny
173are configured so that ssh is not blocked.
174
175Kerberos support
176----------------
177
178ssh is now compiled with Kerberos support. Unfortunately, privilege
179separation is incompatible with Kerberos support for SSH protocol 1 and
180parts of the support for protocol 2; you may need to run kinit after logging
181in.
182
183Interoperability between scp and the ssh.com SSH server
184-------------------------------------------------------
185
186In version 2 and greater of the commercial SSH server produced by SSH
187Communications Security, scp was changed to use SFTP (SSH2's file transfer
188protocol) instead of the traditional rcp-over-ssh, thereby breaking
189compatibility. The OpenSSH developers regard this as a bug in the ssh.com
190server, and do not currently intend to change OpenSSH's scp to match.
191
192Workarounds for this problem are to install scp1 on the server (scp2 will
193fall back to it), to use sftp, or to use some other transfer mechanism such
194as rsync-over-ssh or tar-over-ssh.
195
196Running sshd from inittab
197-------------------------
198
199Some people find it useful to run the sshd server from inittab, to make sure
200that it always stays running. To do this, stop sshd ('/etc/init.d/ssh
201stop'), add the following line to /etc/inittab, and run 'telinit q':
202
203 ss:2345:respawn:/usr/sbin/sshd -D
204
205If you do this, note that you will need to stop sshd being started in the
206normal way ('update-rc.d ssh disable') and that you will need to restart
207this sshd manually on upgrades.

209Per-connection sshd instances with systemd
210------------------------------------------
211
212If you want to reconfigure systemd to listen on port 22 itself and launch an
213instance of sshd for each connection (inetd-style socket activation), then
214you can run:
215
216 systemctl stop ssh.service
217 systemctl start ssh.socket
218
219To make this permanent:
220
221 systemctl disable ssh.service
222 systemctl enable ssh.socket
223
224This may be appropriate in environments where minimal footprint is critical
225(e.g. cloud guests). Be aware that this bypasses MaxStartups, and systemd's
226MaxConnections cannot quite replace this as it cannot distinguish between
227authenticated and unauthenticated connections; see
228https://bugzilla.redhat.com/show_bug.cgi?id=963268 for more discussion.
229
230The provided ssh.socket unit file sets ListenStream=22. If you need to have
231it listen on a different address or port, then you will need to do this by
232copying /lib/systemd/system/ssh.socket to /etc/systemd/system/ssh.socket and
233modifying the ListenStream option. See systemd.socket(5) for details.

4 - SECURITY: sshd(8): Sanitise X11 authentication credentials to avoid
5 xauth command injection when X11Forwarding is enabled
6 (http://www.openssh.com/txt/x11fwd.adv).

10openssh (1:7.2p1-1) unstable; urgency=medium
11
12 * New upstream release (http://www.openssh.com/txt/release-7.2):
13 - This release disables a number of legacy cryptographic algorithms by
14 default in ssh:
15 + Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and
16 the rijndael-cbc aliases for AES.
17 + MD5-based and truncated HMAC algorithms.
18 These algorithms are already disabled by default in sshd.
19 - ssh(1), sshd(8): Remove unfinished and unused roaming code (was
20 already forcibly disabled in OpenSSH 7.1p2).
21 - ssh(1): Eliminate fallback from untrusted X11 forwarding to trusted
22 forwarding when the X server disables the SECURITY extension.
23 - ssh(1), sshd(8): Increase the minimum modulus size supported for
24 diffie-hellman-group-exchange to 2048 bits.
25 - sshd(8): Pre-auth sandboxing is now enabled by default (previous
26 releases enabled it for new installations via sshd_config).
27 - all: Add support for RSA signatures using SHA-256/512 hash algorithms
28 based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt.
29 - ssh(1): Add an AddKeysToAgent client option which can be set to 'yes',
30 'no', 'ask', or 'confirm', and defaults to 'no'. When enabled, a
31 private key that is used during authentication will be added to
32 ssh-agent if it is running (with confirmation enabled if set to
33 'confirm').
34 - sshd(8): Add a new authorized_keys option "restrict" that includes all
35 current and future key restrictions (no-*-forwarding, etc.). Also add
36 permissive versions of the existing restrictions, e.g. "no-pty" ->
37 "pty". This simplifies the task of setting up restricted keys and
38 ensures they are maximally-restricted, regardless of any permissions
39 we might implement in the future.
40 - ssh(1): Add ssh_config CertificateFile option to explicitly list
41 certificates.
42 - ssh-keygen(1): Allow ssh-keygen to change the key comment for all
43 supported formats (closes: #811125).
44 - ssh-keygen(1): Allow fingerprinting from standard input, e.g.
45 "ssh-keygen -lf -" (closes: #509058).
46 - ssh-keygen(1): Allow fingerprinting multiple public keys in a file,
47 e.g. "ssh-keygen -lf ~/.ssh/authorized_keys".
48 - sshd(8): Support "none" as an argument for sshd_config Foreground and
49 ChrootDirectory. Useful inside Match blocks to override a global
50 default.
51 - ssh-keygen(1): Support multiple certificates (one per line) and
52 reading from standard input (using "-f -") for "ssh-keygen -L"
53 - ssh-keyscan(1): Add "ssh-keyscan -c ..." flag to allow fetching
54 certificates instead of plain keys.
55 - ssh(1): Better handle anchored FQDNs (e.g. 'cvs.openbsd.org.') in
56 hostname canonicalisation - treat them as already canonical and remove
57 the trailing '.' before matching ssh_config.
58 - sftp(1): Existing destination directories should not terminate
59 recursive uploads (regression in OpenSSH 6.8; LP: #1553378).
60 * Use HTTPS for Vcs-* URLs, and link to cgit rather than gitweb.
61 * Restore slogin symlinks for compatibility, although they were removed
62 upstream.

77 for roaming, which could be tricked by a malicious server into leaking
78 client memory to the server, including private client user keys; this
79 information leak is restricted to connections to malicious or
80 compromised servers (closes: #810984).
81 - SECURITY: Fix an out of-bound read access in the packet handling code.
82 Reported by Ben Hawkes.
83 - Further use of explicit_bzero has been added in various buffer
84 handling code paths to guard against compilers aggressively doing
85 dead-store removal.

143
144 * New upstream release (http://www.openssh.com/txt/release-7.0, closes:
145 #785190):
146 - Support for the legacy SSH version 1 protocol is disabled by default
147 at compile time.
148 - Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is
149 disabled by default at run-time. It may be re-enabled using the
150 instructions at http://www.openssh.com/legacy.html
151 - Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by
152 default at run-time. These may be re-enabled using the instructions
153 at http://www.openssh.com/legacy.html
154 - Support for the legacy v00 cert format has been removed.
155 - The default for the sshd_config(5) PermitRootLogin option has changed
156 from "yes" to "prohibit-password".
157 - PermitRootLogin=without-password/prohibit-password now bans all
158 interactive authentication methods, allowing only public-key,
159 hostbased and GSSAPI authentication (previously it permitted
160 keyboard-interactive and password-less authentication if those were
161 enabled).
162 - ssh_config(5): Add PubkeyAcceptedKeyTypes option to control which
163 public key types are available for user authentication.
164 - sshd_config(5): Add HostKeyAlgorithms option to control which public
165 key types are offered for host authentications.
166 - ssh(1), sshd(8): Extend Ciphers, MACs, KexAlgorithms,
167 HostKeyAlgorithms, PubkeyAcceptedKeyTypes and HostbasedKeyTypes
168 options to allow appending to the default set of algorithms instead of
169 replacing it. Options may now be prefixed with a '+' to append to the
170 default, e.g. "HostKeyAlgorithms=+ssh-dss".
171 - sshd_config(5): PermitRootLogin now accepts an argument of
172 'prohibit-password' as a less-ambiguous synonym of 'without-
173 password'.
174 - ssh(1), sshd(8): Add compatability workarounds for Cisco and more
175 PuTTY versions.
176 - Fix some omissions and errors in the PROTOCOL and PROTOCOL.mux
177 documentation relating to Unix domain socket forwarding.
178 - ssh(1): Improve the ssh(1) manual page to include a better description
179 of Unix domain socket forwarding (closes: #779068).
180 - ssh(1), ssh-agent(1): Skip uninitialised PKCS#11 slots, fixing
181 failures to load keys when they are present.
182 - ssh(1), ssh-agent(1): Do not ignore PKCS#11 hosted keys that wth empty
183 CKA_ID.
184 - sshd(8): Clarify documentation for UseDNS option.
185 - Check realpath(3) behaviour matches what sftp-server requires and use
186 a replacement if necessary.
187 * New upstream release (http://www.openssh.com/txt/release-7.1):
188 - sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin=
189 prohibit-password/without-password that could, depending on
190 compile-time configuration, permit password authentication to root
191 while preventing other forms of authentication. This problem was
192 reported by Mantas Mikulenas.
193 - ssh(1), sshd(8): Add compatibility workarounds for FuTTY.
194 - ssh(1), sshd(8): Refine compatibility workarounds for WinSCP.
195 - Fix a number of memory faults (double-free, free of uninitialised
196 memory, etc) in ssh(1) and ssh-keygen(1). Reported by Mateusz
197 Kocielski.
198 * Change "PermitRootLogin without-password" to the new preferred spelling
199 of "PermitRootLogin prohibit-password" in sshd_config, and update
200 documentation to reflect the new upstream default.
201 * Enable conch interoperability tests under autopkgtest.

230
231 * New upstream release (http://www.openssh.com/txt/release-6.8):
232 - sshd(8): UseDNS now defaults to 'no'. Configurations that match
233 against the client host name (via sshd_config or authorized_keys) may
234 need to re-enable it or convert to matching against addresses.
235 - Add FingerprintHash option to ssh(1) and sshd(8), and equivalent
236 command-line flags to the other tools to control algorithm used for
237 key fingerprints. The default changes from MD5 to SHA256 and format
238 from hex to base64.
239 Fingerprints now have the hash algorithm prepended. An example of the
240 new format: SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE
241 Please note that visual host keys will also be different.
242 - ssh(1), sshd(8): Experimental host key rotation support. Add a
243 protocol extension for a server to inform a client of all its
244 available host keys after authentication has completed. The client
245 may record the keys in known_hosts, allowing it to upgrade to better
246 host key algorithms and a server to gracefully rotate its keys.
247 The client side of this is controlled by a UpdateHostkeys config
248 option (default off).
249 - ssh(1): Add a ssh_config HostbasedKeyType option to control which host
250 public key types are tried during host-based authentication.
251 - ssh(1), sshd(8): Fix connection-killing host key mismatch errors when
252 sshd offers multiple ECDSA keys of different lengths.
253 - ssh(1): When host name canonicalisation is enabled, try to parse host
254 names as addresses before looking them up for canonicalisation. Fixes
255 bz#2074 and avoids needless DNS lookups in some cases.
256 - ssh(1), ssh-keysign(8): Make ed25519 keys work for host based
257 authentication.
258 - sshd(8): SSH protocol v.1 workaround for the Meyer, et al,
259 Bleichenbacher Side Channel Attack. Fake up a bignum key before RSA
260 decryption.
261 - sshd(8): Remember which public keys have been used for authentication
262 and refuse to accept previously-used keys. This allows
263 AuthenticationMethods=publickey,publickey to require that users
264 authenticate using two _different_ public keys.
265 - sshd(8): add sshd_config HostbasedAcceptedKeyTypes and
266 PubkeyAcceptedKeyTypes options to allow sshd to control what public
267 key types will be accepted (closes: #481133). Currently defaults to
268 all.
269 - sshd(8): Don't count partial authentication success as a failure
270 against MaxAuthTries.
271 - ssh(1): Add RevokedHostKeys option for the client to allow text-file
272 or KRL-based revocation of host keys.
273 - ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates by serial
274 number or key ID without scoping to a particular CA.
275 - ssh(1): Add a "Match canonical" criteria that allows ssh_config Match
276 blocks to trigger only in the second config pass.
277 - ssh(1): Add a -G option to ssh that causes it to parse its
278 configuration and dump the result to stdout, similar to "sshd -T".
279 - ssh(1): Allow Match criteria to be negated. E.g. "Match !host".
280 - ssh-keyscan(1): ssh-keyscan has been made much more robust against
281 servers that hang or violate the SSH protocol (closes: #241119).
282 - ssh(1), ssh-keygen(1): Fix regression bz#2306: Key path names were
283 being lost as comment fields (closes: #787776).
284 - ssh(1): Allow ssh_config Port options set in the second config parse
285 phase to be applied (they were being ignored; closes: #774369).
286 - ssh(1): Tweak config re-parsing with host canonicalisation - make the
287 second pass through the config files always run when host name
288 canonicalisation is enabled (and not whenever the host name changes)
289 - ssh(1): Fix passing of wildcard forward bind addresses when connection
290 multiplexing is in use.
291 - ssh-keygen(1): Fix broken private key conversion from non-OpenSSH
292 formats.
293 - ssh-keygen(1): Fix KRL generation bug when multiple CAs are in use.
294 * New upstream release (http://www.openssh.com/txt/release-6.9):
295 - CVE-2015-5352: ssh(1): When forwarding X11 connections with
296 ForwardX11Trusted=no, connections made after ForwardX11Timeout expired
297 could be permitted and no longer subject to XSECURITY restrictions
298 because of an ineffective timeout check in ssh(1) coupled with "fail
299 open" behaviour in the X11 server when clients attempted connections
300 with expired credentials (closes: #790798). This problem was reported
301 by Jann Horn.
302 - SECURITY: ssh-agent(1): Fix weakness of agent locking (ssh-add -x) to
303 password guessing by implementing an increasing failure delay, storing
304 a salted hash of the password rather than the password itself and
305 using a timing-safe comparison function for verifying unlock attempts.
306 This problem was reported by Ryan Castellucci.
307 - sshd(8): Support admin-specified arguments to AuthorizedKeysCommand
308 (closes: #740494).
309 - sshd(8): Add AuthorizedPrincipalsCommand that allows retrieving
310 authorized principals information from a subprocess rather than a
311 file.
312 - ssh(1), ssh-add(1): Support PKCS#11 devices with external PIN entry
313 devices.
314 - ssh-keygen(1): Support "ssh-keygen -lF hostname" to search known_hosts
315 and print key hashes rather than full keys.
316 - ssh-agent(1): Add -D flag to leave ssh-agent in foreground without
317 enabling debug mode.
318 - ssh(1), sshd(8): Deprecate legacy SSH2_MSG_KEX_DH_GEX_REQUEST_OLD
319 message and do not try to use it against some 3rd-party SSH
320 implementations that use it (older PuTTY, WinSCP).
321 - ssh(1), sshd(8): Cap DH-GEX group size at 4Kbits for Cisco
322 implementations as some would fail when attempting to use group sizes
323 >4K (closes: #740307, LP: #1287222).
324 - ssh(1): Fix out-of-bound read in EscapeChar configuration option
325 parsing.
326 - sshd(8): Fix application of PermitTunnel, LoginGraceTime,
327 AuthenticationMethods and StreamLocalBindMask options in Match blocks.

336 - ssh(1): Allow ListenAddress, Port and AddressFamily configuration
337 options to appear in any order.
338 - sshd(8): Check for and reject missing arguments for VersionAddendum
339 and ForceCommand.
340 - ssh(1), sshd(8): Don't treat unknown certificate extensions as fatal.
341 - ssh-keygen(1): Make stdout and stderr output consistent.
342 - ssh(1): Mention missing DISPLAY environment in debug log when X11

361 * There are some things I want to fix before upgrading to 7.0p1, though I
362 intend to do that soon. In the meantime, backport some patches, mainly
363 to fix security issues:
364 - SECURITY: sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be
365 world-writable. Local attackers may be able to write arbitrary
366 messages to logged-in users, including terminal escape sequences.
367 Reported by Nikolay Edigaryev.
368 - SECURITY: sshd(8): Fixed a privilege separation weakness related to
369 PAM support. Attackers who could successfully compromise the
370 pre-authentication process for remote code execution and who had valid
371 credentials on the host could impersonate other users. Reported by
372 Moritz Jodeit.
373 - SECURITY: sshd(8): Fixed a use-after-free bug related to PAM support
374 that was reachable by attackers who could compromise the
375 pre-authentication process for remote code execution (closes:
376 #795711). Also reported by Moritz Jodeit.
377 - CVE-2015-5600: sshd(8): Fix circumvention of MaxAuthTries using
378 keyboard-interactive authentication (closes: #793616). By specifying
379 a long, repeating keyboard-interactive "devices" string, an attacker
380 could request the same authentication method be tried thousands of
381 times in a single pass. The LoginGraceTime timeout in sshd(8) and any
382 authentication failure delays implemented by the authentication
383 mechanism itself were still applied. Found by Kingcope.
384 - Let principals-command.sh work for noexec /var/run.
385 * Thanks to Jakub Jelen of Red Hat for Fedora's rebased version of the
386 GSSAPI key exchange patch.
387 * Document the Debian-specific change to the default value of
388 ForwardX11Trusted in ssh(1) (closes: #781469).

445
446 * New upstream release (http://www.openssh.com/txt/release-6.7):
447 - sshd(8): The default set of ciphers and MACs has been altered to
448 remove unsafe algorithms. In particular, CBC ciphers and arcfour* are
449 disabled by default. The full set of algorithms remains available if
450 configured explicitly via the Ciphers and MACs sshd_config options.
451 - ssh(1), sshd(8): Add support for Unix domain socket forwarding. A
452 remote TCP port may be forwarded to a local Unix domain socket and
453 vice versa or both ends may be a Unix domain socket (closes: #236718).
454 - ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for ED25519
455 key types.
456 - sftp(1): Allow resumption of interrupted uploads.
457 - ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it is
458 the same as the one sent during initial key exchange.
459 - sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind addresses
460 when GatewayPorts=no; allows client to choose address family.
461 - sshd(8): Add a sshd_config PermitUserRC option to control whether
462 ~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys
463 option.
464 - ssh(1): Add a %C escape sequence for LocalCommand and ControlPath that
465 expands to a unique identifier based on a hash of the tuple of (local
466 host, remote user, hostname, port). Helps avoid exceeding miserly
467 pathname limits for Unix domain sockets in multiplexing control paths.
468 - sshd(8): Make the "Too many authentication failures" message include
469 the user, source address, port and protocol in a format similar to the
470 authentication success / failure messages.
471 - Use CLOCK_BOOTTIME in preference to CLOCK_MONOTONIC when it is
472 available. It considers time spent suspended, thereby ensuring
473 timeouts (e.g. for expiring agent keys) fire correctly (closes:
474 #734553).
475 - Use prctl() to prevent sftp-server from accessing
476 /proc/self/{mem,maps}.
477 * Restore TCP wrappers support, removed upstream in 6.7. It is true that
478 dropping this reduces preauth attack surface in sshd. On the other
479 hand, this support seems to be quite widely used, and abruptly dropping
480 it (from the perspective of users who don't read openssh-unix-dev) could
481 easily cause more serious problems in practice. It's not entirely clear
482 what the right long-term answer for Debian is, but it at least probably
483 doesn't involve dropping this feature shortly before a freeze.
484 * Replace patch to disable OpenSSL version check with an updated version
485 of Kurt Roeckx's patch from #732940 to just avoid checking the status
486 field.
487 * Build-depend on a new enough dpkg-dev for dpkg-buildflags, rather than
488 simply a new enough dpkg.
489 * Simplify debian/rules using /usr/share/dpkg/buildflags.mk.
490 * Use Package-Type rather than XC-Package-Type, now that it is an official
491 field.
492 * Run a subset of the upstream regression test suite at package build
493 time, and the rest of it under autopkgtest.

777 * If the running init daemon is Upstart, then, on the first upgrade to
778 this version, check whether sysvinit is still managing sshd; if so,
779 manually stop it so that it can be restarted under upstart. We do this
780 near the end of the postinst, so it shouldn't result in any appreciable
781 extra window where sshd is not running during upgrade.

785openssh (1:6.2p2-2) unstable; urgency=low
786
787 * Change start condition of Upstart job to be just the standard "runlevel
788 [2345]", rather than "filesystem or runlevel [2345]"; the latter makes
789 it unreasonably difficult to ensure that urandom starts before ssh, and
790 is not really necessary since one of static-network-up and failsafe-boot
791 is guaranteed to happen and will trigger entry to the default runlevel,
792 and we don't care about ssh starting before the network (LP: #1098299).
793 * Drop conffile handling for direct upgrades from pre-split ssh package;
794 this was originally added in 1:4.3p2-7 / 1:4.3p2-8, and contained a
795 truly ghastly hack around a misbehaviour in sarge's dpkg. Since this is
796 now four Debian releases ago, we can afford to drop this and simplify
797 the packaging.
798 * Remove ssh/use_old_init_script, which was a workaround for a very old
799 bug in /etc/init.d/ssh. If anyone has ignored this for >10 years then
800 they aren't going to be convinced now (closes: #214182).
801 * Remove support for upgrading directly from ssh-nonfree.
802 * Remove lots of maintainer script support for direct upgrades from
803 pre-etch (three releases before current stable).
804 * Add #DEBHELPER# tokens to openssh-client.postinst and
805 openssh-server.postinst.
806 * Replace old manual conffile handling code with dpkg-maintscript-helper,
807 via dh_installdeb.
808 * Switch to new unified layout for Upstart jobs as documented in
809 https://wiki.ubuntu.com/UpstartCompatibleInitScripts: the init script
810 checks for a running Upstart, and we now let dh_installinit handle most
811 of the heavy lifting in maintainer scripts. Ubuntu users should be
812 essentially unaffected except that sshd may no longer start
813 automatically in chroots if the running Upstart predates 0.9.0; but the
814 main goal is simply not to break when openssh-server is installed in a
815 chroot.
816 * Remove the check for vulnerable host keys; this was first added five
817 years ago, and everyone should have upgraded through a version that
818 applied these checks by now. The ssh-vulnkey tool and the blacklisting
819 support in sshd are still here, at least for the moment.
820 * This removes the last of our uses of debconf (closes: #221531).
821 * Use the pam_loginuid session module (thanks, Laurent Bigonville; closes:
822 #677440, LP: #1067779).
823 * Bracket our session stack with calls to pam_selinux close/open (thanks,
824 Laurent Bigonville; closes: #679458).
825 * Fix dh_builddeb invocation so that we really use xz compression for
826 binary packages, as intended since 1:6.1p1-2.

1094 - Implement Elliptic Curve Cryptography modes for key exchange (ECDH)

1096 offer better performance than plain DH and DSA at the same equivalent
1097 symmetric key length, as well as much shorter keys.
1098 - sftp(1)/sftp-server(8): add a protocol extension to support a hard
1099 link operation. It is available through the "ln" command in the
1100 client. The old "ln" behaviour of creating a symlink is available
1101 using its "-s" option or through the preexisting "symlink" command.
1102 - scp(1): Add a new -3 option to scp: Copies between two remote hosts
1103 are transferred through the local host (closes: #508613).
1104 - ssh(1): "atomically" create the listening mux socket by binding it on
1105 a temporary name and then linking it into position after listen() has
1106 succeeded. This allows the mux clients to determine that the server
1107 socket is either ready or stale without races (closes: #454784).
1108 Stale server sockets are now automatically removed (closes: #523250).
1109 - ssh(1): install a SIGCHLD handler to reap expired child process
1110 (closes: #594687).

1112 temporary directories (closes: #357469, although only if you arrange
1113 for ssh-agent to actually see $TMPDIR since the setgid bit will cause
1114 it to be stripped off).

1119 add such host keys should manually add 'HostKey
1120 /etc/ssh/ssh_host_ecdsa_key' to /etc/ssh/sshd_config and run 'ssh-keygen

1188 (closes: #581919).
1189 * Check primary group memberships as well as supplementary group
1190 memberships, and only allow group-writability by groups with exactly one
1191 member, as zero-member groups are typically used by setgid binaries
1192 rather than being user-private groups (closes: #581697).

1242
1243 * New upstream release (LP: #535029).
1244 - After a transition period of about 10 years, this release disables SSH
1245 protocol 1 by default. Clients and servers that need to use the
1246 legacy protocol must explicitly enable it in ssh_config / sshd_config
1247 or on the command-line.
1248 - Remove the libsectok/OpenSC-based smartcard code and add support for
1249 PKCS#11 tokens. This support is enabled by default in the Debian
1250 packaging, since it now doesn't involve additional library
1251 dependencies (closes: #231472, LP: #16918).
1252 - Add support for certificate authentication of users and hosts using a
1253 new, minimal OpenSSH certificate format (closes: #482806).
1254 - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...".
1255 - Add the ability to revoke keys in sshd(8) and ssh(1). (For the Debian
1256 package, this overlaps with the key blacklisting facility added in
1257 openssh 1:4.7p1-9, but with different file formats and slightly
1258 different scopes; for the moment, I've roughly merged the two.)
1259 - Various multiplexing improvements, including support for requesting
1260 port-forwardings via the multiplex protocol (closes: #360151).
1261 - Allow setting an explicit umask on the sftp-server(8) commandline to
1262 override whatever default the user has (closes: #496843).
1263 - Many sftp client improvements, including tab-completion, more options,
1264 and recursive transfer support for get/put (LP: #33378). The old
1265 mget/mput commands never worked properly and have been removed
1266 (closes: #270399, #428082).
1267 - Do not prompt for a passphrase if we fail to open a keyfile, and log
1268 the reason why the open failed to debug (closes: #431538).
1269 - Prevent sftp from crashing when given a "-" without a command. Also,
1270 allow whitespace to follow a "-" (closes: #531561).
1271
1272 * Fix 'debian/rules quilt-setup' to avoid writing .orig files if some
1273 patches apply with offsets.
1274 * Include debian/ssh-askpass-gnome.png in the Debian tarball now that
1275 we're using a source format that permits this, rather than messing
1276 around with uudecode.
1277 * Drop compatibility with the old gssapi mechanism used in ssh-krb5 <<
1278 3.8.1p1-1. Simon Wilkinson refused this patch since the old gssapi
1279 mechanism was removed due to a serious security hole, and since these
1280 versions of ssh-krb5 are no longer security-supported by Debian I don't
1281 think there's any point keeping client compatibility for them.
1282 * Fix substitution of ETC_PAM_D_SSH, following the rename in 1:4.7p1-4.
1283 * Hardcode the location of xauth to /usr/bin/xauth rather than
1284 /usr/bin/X11/xauth (thanks, Aron Griffis; closes: #575725, LP: #8440).
1285 xauth no longer depends on x11-common, so we're no longer guaranteed to
1286 have the /usr/bin/X11 symlink available. I was taking advantage of the
1287 /usr/bin/X11 symlink to smooth X's move to /usr/bin, but this is far
1288 enough in the past now that it's probably safe to just use /usr/bin.
1289 * Remove SSHD_OOM_ADJUST configuration. sshd now unconditionally makes
1290 itself non-OOM-killable, and doesn't require configuration to avoid log
1291 spam in virtualisation containers (closes: #555625).
1292 * Drop Debian-specific removal of OpenSSL version check. Upstream ignores
1293 the two patchlevel nybbles now, which is sufficient to address the
1294 original reason this change was introduced, and it appears that any
1295 change in the major/minor/fix nybbles would involve a new libssl package
1296 name. (We'd still lose if the status nybble were ever changed, but that
1297 would mean somebody had packaged a development/beta version rather than
1298 a proper release, which doesn't appear to be normal practice.)
1299 * Drop most of our "LogLevel SILENT" (-qq) patch. This was originally
1300 introduced to match the behaviour of non-free SSH, in which -q does not
1301 suppress fatal errors, but matching the behaviour of OpenSSH upstream is
1302 much more important nowadays. We no longer document that -q does not
1303 suppress fatal errors (closes: #280609). Migrate "LogLevel SILENT" to
1304 "LogLevel QUIET" in sshd_config on upgrade.
1305 * Policy version 3.8.4:
1306 - Add a Homepage field.

1340 * Backport from upstream:
1341 - Do not fall back to adding keys without constraints (ssh-add -c / -t
1342 ...) when the agent refuses the constrained add request. This was a
1343 useful migration measure back in 2002 when constraints were new, but
1344 just adds risk now (LP: #209447).
1345 * Drop change from 1:3.8p1-3 to avoid setresuid() and setresgid() system
1346 calls. This only applied to Linux 2.2, which it's no longer feasible to
1347 run anyway (see 1:5.2p1-2 changelog).

1354 * Backport from upstream:
1355 - After sshd receives a SIGHUP, ignore subsequent HUPs while sshd
1356 re-execs itself. Prevents two HUPs in quick succession from resulting
1357 in sshd dying (LP: #497781).
1358 - Output a debug if we can't open an existing keyfile (LP: #505301).
1359 * Use host compiler for ssh-askpass-gnome when cross-compiling.
1360 * Don't run tests when cross-compiling.
1361 * Drop change from 1:3.6.1p2-5 to disable cmsg_type check for file
1362 descriptor passing when running on Linux 2.0. The previous stable
1363 release of Debian dropped support for Linux 2.4, let alone 2.0, so this

1377 - Change the default cipher order to prefer the AES CTR modes and the
1378 revised "arcfour256" mode to CBC mode ciphers that are susceptible to
1379 CPNI-957037 "Plaintext Recovery Attack Against SSH".
1380 - Add countermeasures to mitigate CPNI-957037-style attacks against the
1381 SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid
1382 packet length or Message Authentication Code, ssh/sshd will continue
1383 reading up to the maximum supported packet length rather than
1384 immediately terminating the connection. This eliminates most of the
1385 known differences in behaviour that leaked information about the
1386 plaintext of injected data which formed the basis of this attack
1387 (closes: #506115, LP: #379329).
1388 - ForceCommand directive now accepts commandline arguments for the
1389 internal-sftp server (closes: #524423, LP: #362511).
1390 - Add AllowAgentForwarding to available Match keywords list (closes:
1391 #540623).
1392 - Make ssh(1) send the correct channel number for
1393 SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to
1394 avoid triggering 'Non-public channel' error messages on sshd(8) in
1395 openssh-5.1.
1396 - Avoid printing 'Non-public channel' warnings in sshd(8), since the
1397 ssh(1) has sent incorrect channel numbers since ~2004 (this reverts a
1398 behaviour introduced in openssh-5.1; closes: #496017).

1400 connections (closes: #507541).

1533 * New upstream release (closes: #474301). Important changes not previously
1534 backported to 4.7p1:
1535 - 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9):
1536 + Added chroot(2) support for sshd(8), controlled by a new option
1537 "ChrootDirectory" (closes: #139047, LP: #24777).
1538 + Linked sftp-server(8) into sshd(8). The internal sftp server is used
1539 when the command "internal-sftp" is specified in a Subsystem or
1540 ForceCommand declaration. When used with ChrootDirectory, the
1541 internal sftp server requires no special configuration of files
1542 inside the chroot environment.
1543 + Added a protocol extension method "posix-rename@openssh.com" for
1544 sftp-server(8) to perform POSIX atomic rename() operations; sftp(1)
1545 prefers this if available (closes: #308561).
1546 + Removed the fixed limit of 100 file handles in sftp-server(8).
1547 + ssh(8) will now skip generation of SSH protocol 1 ephemeral server
1548 keys when in inetd mode and protocol 2 connections are negotiated.
1549 This speeds up protocol 2 connections to inetd-mode servers that
1550 also allow Protocol 1.
1551 + Accept the PermitRootLogin directive in a sshd_config(5) Match
1552 block. Allows for, e.g. permitting root only from the local network.
1553 + Reworked sftp(1) argument splitting and escaping to be more
1554 internally consistent (i.e. between sftp commands) and more
1555 consistent with sh(1). Please note that this will change the
1556 interpretation of some quoted strings, especially those with
1557 embedded backslash escape sequences.
1558 + Support "Banner=none" in sshd_config(5) to disable sending of a
1559 pre-login banner (e.g. in a Match block).
1560 + ssh(1) ProxyCommands are now executed with $SHELL rather than
1561 /bin/sh.
1562 + ssh(1)'s ConnectTimeout option is now applied to both the TCP
1563 connection and the SSH banner exchange (previously it just covered
1564 the TCP connection). This allows callers of ssh(1) to better detect
1565 and deal with stuck servers that accept a TCP connection but don't
1566 progress the protocol, and also makes ConnectTimeout useful for
1567 connections via a ProxyCommand.
1568 + scp(1) incorrectly reported "stalled" on slow copies (closes:
1569 #140828).
1570 + scp(1) date underflow for timestamps before epoch.
1571 + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS,
1572 instead of the current standard RRSIG.
1573 + Correctly drain ACKs when a sftp(1) upload write fails midway,
1574 avoids a fatal() exit from what should be a recoverable condition.
1575 + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF
1576 hostname") to not include any IP address in the data to be hashed.
1577 + Make ssh(1) skip listening on the IPv6 wildcard address when a
1578 binding address of 0.0.0.0 is used against an old SSH server that
1579 does not support the RFC4254 syntax for wildcard bind addresses.
1580 + Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is
1581 already done for X11/TCP forwarding sockets (closes: #439661).
1582 + Fix FD leak that could hang a ssh(1) connection multiplexing master.
1583 + Make ssh(1) -q option documentation consistent with reality.
1584 + Fixed sshd(8) PAM support not calling pam_session_close(), or
1585 failing to call it with root privileges (closes: #372680).
1586 + Fix activation of OpenSSL engine support when requested in configure
1587 (LP: #119295).
1588 + Cache SELinux status earlier so we know if it's enabled after a
1589 chroot (LP: #237557).
1590 - 5.1/5.1p1 (http://www.openssh.com/txt/release-5.1):
1591 + Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1)
1592 and ssh-keygen(1). Visual fingerprint display is controlled by a new
1593 ssh_config(5) option "VisualHostKey". The intent is to render SSH
1594 host keys in a visual form that is amenable to easy recall and
1595 rejection of changed host keys.
1596 + sshd_config(5) now supports CIDR address/masklen matching in "Match
1597 address" blocks, with a fallback to classic wildcard matching.
1598 + sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys
1599 from="..." restrictions, also with a fallback to classic wildcard
1600 matching.
1601 + Added an extended test mode (-T) to sshd(8) to request that it write
1602 its effective configuration to stdout and exit. Extended test mode
1603 also supports the specification of connection parameters (username,
1604 source address and hostname) to test the application of
1605 sshd_config(5) Match rules.
1606 + ssh(1) now prints the number of bytes transferred and the overall
1607 connection throughput for SSH protocol 2 sessions when in verbose
1608 mode (previously these statistics were displayed for protocol 1
1609 connections only).
1610 + sftp-server(8) now supports extension methods statvfs@openssh.com
1611 and fstatvfs@openssh.com that implement statvfs(2)-like operations.
1612 + sftp(1) now has a "df" command to the sftp client that uses the
1613 statvfs@openssh.com to produce a df(1)-like display of filesystem
1614 space and inode utilisation (requires statvfs@openssh.com support on
1615 the server).
1616 + Added a MaxSessions option to sshd_config(5) to allow control of the
1617 number of multiplexed sessions supported over a single TCP
1618 connection. This allows increasing the number of allowed sessions
1619 above the previous default of 10, disabling connection multiplexing
1620 (MaxSessions=1) or disallowing login/shell/subsystem sessions
1621 entirely (MaxSessions=0).
1622 + Added a no-more-sessions@openssh.com global request extension that
1623 is sent from ssh(1) to sshd(8) when the client knows that it will
1624 never request another session (i.e. when session multiplexing is
1625 disabled). This allows a server to disallow further session requests
1626 and terminate the session in cases where the client has been
1627 hijacked.
1628 + ssh-keygen(1) now supports the use of the -l option in combination
1629 with -F to search for a host in ~/.ssh/known_hosts and display its
1630 fingerprint.
1631 + ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of
1632 "rsa1" (LP: #129794).
1633 + Added an AllowAgentForwarding option to sshd_config(8) to control
1634 whether authentication agent forwarding is permitted. Note that this
1635 is a loose control, as a client may install their own unofficial
1636 forwarder.
1637 + ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when
1638 receiving network data, resulting in a ~10% speedup.
1639 + ssh(1) and sshd(8) will now try additional addresses when connecting
1640 to a port forward destination whose DNS name resolves to more than
1641 one address. The previous behaviour was to try the only first
1642 address and give up if that failed.
1643 + ssh(1) and sshd(8) now support signalling that channels are
1644 half-closed for writing, through a channel protocol extension
1645 notification "eow@openssh.com". This allows propagation of closed
1646 file descriptors, so that commands such as "ssh -2 localhost od
1647 /bin/ls | true" do not send unnecessary data over the wire.
1648 + sshd(8): increased the default size of ssh protocol 1 ephemeral keys
1649 from 768 to 1024 bits.
1650 + When ssh(1) has been requested to fork after authentication ("ssh
1651 -f") with ExitOnForwardFailure enabled, delay the fork until after
1652 replies for any -R forwards have been seen. Allows for robust
1653 detection of -R forward failure when using -f.
1654 + "Match group" blocks in sshd_config(5) now support negation of
1655 groups. E.g. "Match group staff,!guests".
1656 + sftp(1) and sftp-server(8) now allow chmod-like operations to set
1657 set[ug]id/sticky bits.
1658 + The MaxAuthTries option is now permitted in sshd_config(5) match
1659 blocks.
1660 + Multiplexed ssh(1) sessions now support a subset of the ~ escapes
1661 that are available to a primary connection.
1662 + ssh(1) connection multiplexing will now fall back to creating a new
1663 connection in most error cases (closes: #352830).
1664 + Make ssh(1) deal more gracefully with channel requests that fail.
1665 Previously it would optimistically assume that requests would always
1666 succeed, which could cause hangs if they did not (e.g. when the
1667 server runs out of file descriptors).
1668 + ssh(1) now reports multiplexing errors via the multiplex slave's
1669 stderr where possible (subject to LogLevel in the mux master).
1670 + Fixed an UMAC alignment problem that manifested on Itanium
1671 platforms.
1672 * Remove our local version of moduli(5) now that there's one upstream.
1673 * Say "GTK+" rather than "GTK" in ssh-askpass-gnome's description.
1674 * Add lintian overrides for empty /usr/share/doc/openssh-client
1675 directories in openssh-server and ssh (necessary due to being symlink
1676 targets).

1915 creation of an untrusted cookie fails; found and fixed by Jan Pechanec
1916 (closes: #444738).
1917 - sshd(8) in new installations defaults to SSH Protocol 2 only. Existing
1918 installations are unchanged.
1919 - The SSH channel window size has been increased, and both ssh(1)
1920 sshd(8) now send window updates more aggressively. These improves
1921 performance on high-BDP (Bandwidth Delay Product) networks.
1922 - ssh(1) and sshd(8) now preserve MAC contexts between packets, which
1923 saves 2 hash calls per packet and results in 12-16% speedup for
1924 arcfour256/hmac-md5.
1925 - A new MAC algorithm has been added, UMAC-64 (RFC4418) as
1926 "umac-64@openssh.com". UMAC-64 has been measured to be approximately
1927 20% faster than HMAC-MD5.
1928 - Failure to establish a ssh(1) TunnelForward is now treated as a fatal
1929 error when the ExitOnForwardFailure option is set.
1930 - ssh(1) returns a sensible exit status if the control master goes away
1931 without passing the full exit status.
1932 - When using a ProxyCommand in ssh(1), set the outgoing hostname with
1933 gethostname(2), allowing hostbased authentication to work.
1934 - Make scp(1) skip FIFOs rather than hanging (closes: #246774).
1935 - Encode non-printing characters in scp(1) filenames. These could cause
1936 copies to be aborted with a "protocol error".
1937 - Handle SIGINT in sshd(8) privilege separation child process to ensure
1938 that wtmp and lastlog records are correctly updated.
1939 - Report GSSAPI mechanism in errors, for libraries that support multiple
1940 mechanisms.
1941 - Improve documentation for ssh-add(1)'s -d option.
1942 - Rearrange and tidy GSSAPI code, removing server-only code being linked
1943 into the client.
1944 - Delay execution of ssh(1)'s LocalCommand until after all forwardings

2063
2064 * New upstream release (closes: #395507, #397961, #420035). Important
2065 changes not previously backported to 4.3p2:
2066 - 4.4/4.4p1 (http://www.openssh.org/txt/release-4.4):
2067 + On portable OpenSSH, fix a GSSAPI authentication abort that could be
2068 used to determine the validity of usernames on some platforms.
2069 + Implemented conditional configuration in sshd_config(5) using the
2070 "Match" directive. This allows some configuration options to be
2071 selectively overridden if specific criteria (based on user, group,
2072 hostname and/or address) are met. So far a useful subset of
2073 post-authentication options are supported and more are expected to
2074 be added in future releases.
2075 + Add support for Diffie-Hellman group exchange key agreement with a
2076 final hash of SHA256.
2077 + Added a "ForceCommand" directive to sshd_config(5). Similar to the
2078 command="..." option accepted in ~/.ssh/authorized_keys, this forces
2079 the execution of the specified command regardless of what the user
2080 requested. This is very useful in conjunction with the new "Match"
2081 option.
2082 + Add a "PermitOpen" directive to sshd_config(5). This mirrors the
2083 permitopen="..." authorized_keys option, allowing fine-grained
2084 control over the port-forwardings that a user is allowed to
2085 establish.
2086 + Add optional logging of transactions to sftp-server(8).
2087 + ssh(1) will now record port numbers for hosts stored in
2088 ~/.ssh/known_hosts when a non-standard port has been requested
2089 (closes: #50612).
2090 + Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a
2091 non-zero exit code) when requested port forwardings could not be
2092 established.
2093 + Extend sshd_config(5) "SubSystem" declarations to allow the
2094 specification of command-line arguments.
2095 + Replacement of all integer overflow susceptible invocations of
2096 malloc(3) and realloc(3) with overflow-checking equivalents.
2097 + Many manpage fixes and improvements.
2098 + Add optional support for OpenSSL hardware accelerators (engines),
2099 enabled using the --with-ssl-engine configure option.
2100 + Tokens in configuration files may be double-quoted in order to
2101 contain spaces (closes: #319639).
2102 + Move a debug() call out of a SIGCHLD handler, fixing a hang when the
2103 session exits very quickly (closes: #307890).
2104 + Fix some incorrect buffer allocation calculations (closes: #410599).
2105 + ssh-add doesn't ask for a passphrase if key file permissions are too
2106 liberal (closes: #103677).
2107 + Likewise, ssh doesn't ask either (closes: #99675).
2108 - 4.6/4.6p1 (http://www.openssh.org/txt/release-4.6):
2109 + sshd now allows the enabling and disabling of authentication methods
2110 on a per user, group, host and network basis via the Match directive
2111 in sshd_config.
2112 + Fixed an inconsistent check for a terminal when displaying scp
2113 progress meter (closes: #257524).
2114 + Fix "hang on exit" when background processes are running at the time
2115 of exit on a ttyful/login session (closes: #88337).
2116 * Update to current GSSAPI patch from
2117 http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch;
2118 install ChangeLog.gssapi.
2119 * Build the .deb --with-ssl-engine (closes: #408027, LP: #119295).
2120 * Use LSB functions in init scripts, and add an LSB-style header (partly
2121 from Ubuntu and partly thanks to Christian Perrier; closes: #389038).
2122 * Move init script start links to S16, move rc1 stop link to K84, and
2123 remove rc0 and rc6 stop links altogether (the last part from Ubuntu;
2124 closes: #122188).
2125 * Emit a slightly more informative message from the init script if
2126 /dev/null has somehow become not a character device (closes: #369964).
2127 * Belatedly build-depend on zlib1g-dev (>= 1:1.2.3-1) (closes: #333447).
2128 * Merge from Ubuntu:
2129 - Build position-independent executables (only for debs, not for udebs)
2130 to take advantage of address space layout randomisation.
2131 - If building on Ubuntu, add /sbin, /usr/sbin, and /usr/local/sbin to
2132 the default path.
2133 * Use ${binary:Version} rather than ${Source-Version} in openssh-server ->
2134 openssh-client dependency.

2204 [ Colin Watson ]
2205 * Drop versioning on ssh/ssh-krb5 Replaces, as otherwise it isn't
2206 sufficient to replace conffiles (closes: #402804).
2207 * Make GSSAPICleanupCreds a compatibility alias for
2208 GSSAPICleanupCredentials. Mark GSSUseSessionCCache and
2209 GSSAPIUseSessionCredCache as known-but-unsupported options, and migrate
2210 away from them on upgrade.
2211 * It turns out that the people who told me that removing a conffile in the
2212 preinst was sufficient to have dpkg replace it without prompting when
2213 moving a conffile between packages were very much mistaken. As far as I
2214 can tell, the only way to do this reliably is to write out the desired
2215 new text of the conffile in the preinst. This is gross, and requires
2216 shipping the text of all conffiles in the preinst too, but there's
2217 nothing for it. Fortunately this nonsense is only required for smooth
2218 upgrades from sarge.

2333
2334 * New upstream release (closes: #361032).
2335 - CVE-2006-0225: scp (as does rcp, on which it is based) invoked a
2336 subshell to perform local to local, and remote to remote copy
2337 operations. This subshell exposed filenames to shell expansion twice;
2338 allowing a local attacker to create filenames containing shell
2339 metacharacters that, if matched by a wildcard, could lead to execution
2340 of attacker-specified commands with the privilege of the user running
2341 scp (closes: #349645).
2342 - Add support for tunneling arbitrary network packets over a connection
2343 between an OpenSSH client and server via tun(4) virtual network
2344 interfaces. This allows the use of OpenSSH (4.3+) to create a true VPN
2345 between the client and server providing real network connectivity at
2346 layer 2 or 3. This feature is experimental.
2347 - Reduce default key length for new DSA keys generated by ssh-keygen
2348 back to 1024 bits. DSA is not specified for longer lengths and does
2349 not fully benefit from simply making keys longer. As per FIPS 186-2
2350 Change Notice 1, ssh-keygen will refuse to generate a new DSA key
2351 smaller or larger than 1024 bits.
2352 - Fixed X forwarding failing to start when the X11 client is executed in
2353 background at the time of session exit.
2354 - Change ssh-keygen to generate a protocol 2 RSA key when invoked
2355 without arguments (closes: #114894).
2356 - Fix timing variance for valid vs. invalid accounts when attempting
2357 Kerberos authentication.
2358 - Ensure that ssh always returns code 255 on internal error
2359 (closes: #259865).
2360 - Cleanup wtmp files on SIGTERM when not using privsep.
2361 - Set SO_REUSEADDR on X11 listeners to avoid problems caused by
2362 lingering sockets from previous session (X11 applications can
2363 sometimes not connect to 127.0.0.1:60xx) (closes:
2364 https://launchpad.net/bugs/25528).
2365 - Ensure that fds 0, 1 and 2 are always attached in all programs, by
2366 duping /dev/null to them if necessary.
2367 - Xauth list invocation had bogus "." argument.
2368 - Remove internal assumptions on key exchange hash algorithm and output
2369 length, preparing OpenSSH for KEX methods with alternate hashes.
2370 - Ignore junk sent by a server before it sends the "SSH-" banner.
2371 - Many manual page improvements.
2372 - Lots of cleanups, including fixes to memory leaks on error paths and
2373 possible crashes.
2374 * Update to current GSSAPI patch from
2375 http://www.sxw.org.uk/computing/patches/openssh-4.3p2-gsskex-20060223.patch
2376 (closes: #352042).
2377 * debian/rules: Resynchronise CFLAGS with that generated by configure.
2378 * Restore pam_nologin to /etc/pam.d/ssh; sshd no longer checks this itself
2379 when PAM is enabled, but relies on PAM to do it.
2380 * Rename KeepAlive to TCPKeepAlive in default sshd_config
2381 (closes: #349896).
2382 * Rephrase ssh/new_config and ssh/encrypted_host_key_but_no_keygen debconf
2383 templates to make boolean short descriptions end with a question mark
2384 and to avoid use of the first person.
2385 * Ship README.tun.

2480 - SECURITY (CAN-2005-2797): Fix a bug introduced in OpenSSH 4.0 that

2482 port forwardings when no listen address was explicitly specified
2483 (closes: #326065).

2485 credentials. This code is only built in openssh-krb5, not openssh, but
2486 I mention the CVE reference here anyway for completeness.
2487 - Add a new compression method ("Compression delayed") that delays zlib
2488 compression until after authentication, eliminating the risk of zlib
2489 vulnerabilities being exploited by unauthenticated users. Note that
2490 users of OpenSSH versions earlier than 3.5 will need to disable
2491 compression on the client or set "Compression yes" (losing this
2492 security benefit) on the server.
2493 - Increase the default size of new RSA/DSA keys generated by ssh-keygen
2494 from 1024 to 2048 bits (closes: #181162).

2501 At least when X11UseLocalhost is turned on, which is the default, the
2502 security risks of using X11 forwarding are risks to the client, not to

2554 then there should be no performance hit for machines not actively
2555 running SELinux.
2556 - Modified the preinst and postinst to call restorecon to set the

2559 may want to also include pam_selinux.so.

2581 * Since ssh-keysign isn't used by default (you need to set

2625 managing known_hosts files, which understand hashing.
2626 - sftp supports command history and editing support using libedit
2627 (closes: #287013).
2628 - Have scp and sftp wait for the spawned ssh to exit before they exit
2629 themselves, allowing ssh to restore terminal modes (closes: #257130).
2630 - Improved the handling of bad data in authorized_keys files,
2631 eliminating fatal errors on corrupt or very large keys; e.g. linefeeds
2632 in keys only produce errors in auth.log now (closes: #220726).

2757 * Split the ssh binary package into openssh-client and openssh-server
2758 (closes: #39741). openssh-server depends on openssh-client for some
2759 common functionality; it didn't seem worth creating yet another package
2760 for this. openssh-client is priority standard, openssh-server optional.
2761 * New transitional ssh package, priority optional, depending on
2762 openssh-client and openssh-server. May be removed once nothing depends
2763 on it.
2764 * When upgrading from ssh to openssh-{client,server}, it's very difficult
2765 for the maintainer scripts to find out what version we're upgrading from
2766 without dodgy dpkg hackery. I've therefore taken the opportunity to move
2767 a couple of debconf notes into NEWS files, namely ssh/ssh2_keys_merged
2768 and ssh/user_environment_tell.
2769 * Add a heuristic to try to make sure the sshd_config upgrade to >= 3.7
2770 happens even though we don't know what version we're upgrading from.
2771 * Remove /etc/ssh/sshd_not_to_be_run on purge of openssh-server. For now
2772 (until sarge+2) it's still honoured to avoid breaking existing
2773 configurations, but the right approach is now to remove the
2774 openssh-server package if you don't want to run the server. Add a NEWS
2775 item to that effect.

2944 - New PAM implementation based on that in FreeBSD. This runs PAM session
2945 modules before dropping privileges (closes: #132681, #150968).
2946 - Since PAM session modules are run as root, we can turn pam_limits back
2947 on by default, and it no longer spits out "Operation not permitted" to
2948 syslog (closes: #171673).
2949 - Password expiry works again (closes: #153235).
2950 - 'ssh -q' suppresses login banner (closes: #134589).
2951 - sshd doesn't lie to PAM about invalid usernames (closes: #157078).
2952 - ssh-add prints key comment on each prompt (closes: #181869).
2953 - Punctuation formatting fixed in man pages (closes: #191131).
2954 - EnableSSHKeysign documented in ssh_config(5) (closes: #224457).
2955 * Add 'UsePAM yes' to /etc/ssh/sshd_config on upgrade from versions older
2956 than this, to maintain the standard Debian sshd configuration.
2957 * Comment out PAMAuthenticationViaKbdInt and RhostsAuthentication in
2958 sshd_config on upgrade. Neither option is supported any more.
2959 * Privilege separation and PAM are now properly supported together, so
2960 remove both debconf questions related to them and simply set it
2961 unconditionally in newly generated sshd_config files (closes: #228838).
2962 * ServerAliveInterval implemented upstream, so ProtocolKeepAlives is now a
2963 compatibility alias. The semantics differ slightly, though; see
2964 ssh_config(5) for details.
2965 * Implement SSH1 support for ServerAliveInterval using SSH_MSG_IGNORE. As
2966 documented in ssh_config(5), it's not as good as the SSH2 version.
2967 * Remove -fno-builtin-log, -DHAVE_MMAP_ANON_SHARED, and
2968 -D__FILE_OFFSET_BITS=64 compiler options, which are no longer necessary.
2969 * Update config.guess and config.sub from autotools-dev 20040105.1.

3099 * Update French debconf template translation (thanks, Christian Perrier;
3100 closes: #194323).
3101 * Version the adduser dependency for --no-create-home (closes: #195756).
3102 * Add a version of moduli(5), namely revision 1.7 of
3103 http://www.openbsd.org/cgi-bin/cvsweb/src/share/man/man5/moduli.5 with
3104 '/etc/moduli' changed to '/etc/ssh/moduli' throughout (closes: #196061).

3110 * Force /etc/default/ssh to be non-executable, since dpkg apparently

3112 * Use debconf 0.5's seen flag rather than the deprecated isdefault.
3113 * Add GPL location to copyright file.
3114 * Remove debian/postinst.old.
3115 * Switch to po-debconf, with some careful manual use of po2debconf to
3116 ensure that the source package continues to build smoothly on woody
3117 (closes: #183986).
3118 * Update debconf template translations:
3119 - Brazilian Portugese (thanks, Andre Luis Lopes; see #183986).
3120 - Japanese (thanks, Tomohiro KUBOTA; closes: #192429).
3121 * Compile with -fno-builtin-log for now, otherwise gcc-3.3 complains
3122 "log.h:59: warning: conflicting types for built-in function `log'". The
3123 OpenSSH log() function has been renamed in upstream CVS.

3131 * Fix ChallengeResponseAuthentication default in generated sshd_config
3132 (closes: #106037).
3133 * Put newlines after full stops in man page documentation for
3134 ProtocolKeepAlives and SetupTimeOut.
3135 * Policy version 3.5.9: support DEB_BUILD_OPTIONS=noopt, build
3136 gnome-ssh-askpass with -g and -Wall flags.
3137 * Really ask ssh/new_config debconf question before trying to fetch its
3138 value (closes: #188721).
3139 * On purge, remove only the files we know about in /etc/ssh rather than
3140 the whole thing, and remove the directory if that leaves it empty
3141 (closes: #176679).
3142 * ssh has depended on debconf for some time now with no complaints, so:
3143 - Simplify the postinst by relying on debconf being present. (The absent
3144 case was buggy anyway.)
3145 - Get rid of "if you have not installed debconf" text in README.Debian,
3146 and generally update the "/usr/bin/ssh not SUID" entry.
3147 * More README.Debian work:
3148 - Reorganize into "UPGRADE ISSUES" and "OTHER ISSUES", in an effort to
3149 make it easier for people to find the former. The upgrade issues
3150 should probably be sorted by version somehow.
3151 - Document X11UseLocalhost under "X11 Forwarding" (closes: #150913).
3152 * Fix setting of IP flags for interactive sessions (upstream bug #541).

3167 - Workaround applied upstream for a bug in the interaction of glibc's
3168 getaddrinfo() with the Linux 2.2 kernel (closes: #155814).
3169 - As such, it should now be safe to remove --with-ipv4-default, so
3170 starting sshd with -6 is no longer necessary (closes: #79861 and lots
3171 of other merged bugs).
3172 - ssh-copy-id prints usage when run without arguments (closes: #71376).
3173 - scp exits 1 if ssh fails (closes: #138400).
3174 - sshd writes to utmp's ut_addr_v6 field in IPv6 mode (closes: #167867).
3175 - 'ssh-add -c' causes ssh-agent to ask the user each time a key is used
3176 (closes: #109795).

3185 * Change the default superuser path to include /sbin, /usr/sbin, and
3186 /usr/local/sbin (closes: #128235, #151267). Using login.defs would be
3187 nice, but that belongs to another package. Without a defined API to
3188 retrieve its settings, parsing it is off-limits.
3189 * Build ssh-askpass-gnome with GNOME 2. The source package should still
3190 support building on stable with GNOME 1, using the alternate
3191 libgnome-dev build-dependency (thanks, Colin Walters; closes: #167582).

3198 than ssh (closes: #121103, #151666). Fix alternative removal to match;
3199 previously it was completely wrong anyway.
3200 * Find out whether /etc/ssh/sshd_not_to_be_run exists and set the debconf
3201 question's default using that information, rather than using debconf as
3202 a registry. Other solutions may be better in the long run, but this is
3203 at least correct (thanks, Matthew Woodcraft; closes: #84725).
3204 * Stop using pam_lastlog, as it doesn't currently work well as a session
3205 module when privilege separation is enabled; it can usually read
3206 /var/log/lastlog but can't write to it. Instead, just use sshd's
3207 built-in support, already enabled by default (closes: #151297, #169938).
3208 * Use 'ssh-keygen -q' rather than redirecting output to /dev/null.
3209 * Add a "this may take some time" warning when creating host keys on
3210 installation (part of #110094).
3211 * When restarting via the init script, check for sshd_not_to_be_run after
3212 stopping sshd (idea from Tomas Pospisek; closes: #149850).
3213 * Append /usr/sbin:/sbin to the init script's $PATH, just in case of
3214 strangeness (closes: #115138).
3215 * Fix a dpkg-statoverride call to redirect stdout to /dev/null, not
3216 stderr.
3217 * Correct copyright file typo: "orignal" -> "original" (closes: #176490).
3218 * Rebuild with libssl0.9.7 (closes: #176983).
3219 * We're up to policy version 3.5.6. DEB_BUILD_OPTIONS stuff still needs to

3228 (closes: #150974).
3229 * Remove some duplication from the postinst's ssh-keysign setuid code.
3230 * Replace db_text with db_input throughout debian/config. (db_text has
3231 been a compatibility wrapper since debconf 0.1.5.)
3232 * Warn about PermitUserEnvironment on upgrade (closes: #167895).
3233 * Use 'make install-nokeys', and disable unused debhelper commands,
3234 thereby forward-porting the last pieces of Zack Weinberg's patch
3235 (closes: #68341).
3236 * Move the man page for gnome-ssh-askpass from the ssh package to
3237 ssh-askpass-gnome (closes: #174449).
3238 * Build with -DLOGIN_NO_ENDOPT, since Debian's /bin/login doesn't accept
3239 '--' to terminate the list of options (closes: #171554).

3261 - Fixes typo in ssh-add usage (closes: #152239).
3262 - Fixes 'PermitRootLogin forced-commands-only' (closes: #166184).
3263 - ~/.ssh/environment and environment= options in ~/.ssh/authorized_keys
3264 are deprecated for security reasons and will eventually go away. For
3265 now they can be re-enabled by setting 'PermitUserEnvironment yes' in
3266 sshd_config.
3267 - ssh-agent is installed setgid to prevent ptrace() attacks. The group
3268 actually doesn't matter, as it drops privileges immediately, but to
3269 avoid confusion the postinst creates a new 'ssh' group for it.
3270 * Obsolete patches:
3271 - Solar Designer's privsep+compression patch for Linux 2.2 (see
3272 1:3.3p1-0.0woody1).
3273 - Hostbased auth ssh-keysign backport (see 1:3.4p1-4).
3274
3275 * Remove duplicated phrase in ssh_config(5) (closes: #152404).
3276 * Source the debconf confmodule at the top of the postrm rather than at
3277 the bottom, to avoid making future non-idempotency problems worse (see
3278 #151035).
3279 * Debconf templates:

4061 gets EOF (closes: #58904)

4063 * Added else-clauses to config to make this upgradepath possible:
4064 oldssh -> openssh preinst fails due to upgrade_to_openssh=false
4065 -> ssh-nonfree -> openssh. Without these, debconf remembered
4066 the old answer, config didn't force asking it, and preinst always
4067 aborted (closes: #56596, #57782)
4068 * Moved setting upgrade_to_openssh isdefault flag to the place
4069 where preinst would abort. This means no double question to most
4070 users, people who currently suffer from "can't upgrade" may need
4071 to run apt-get install ssh twice. Did not do the same for
4072 use_old_init_script, as the situation is a bit different, and
4073 less common (closes: #54010, #56224)
4074 * Check for existance of ssh-keygen before attempting to use it in
4075 preinst, added warning for non-existant ssh-keygen in config. This
4076 happens when the old ssh is removed (say, due to ssh-nonfree getting
4077 installed).

22 This is the portable version of OpenSSH, a free implementation of
23 the Secure Shell protocol as specified by the IETF secsh working
24 group.
25 .
26 Ssh (Secure Shell) is a program for logging into a remote machine
27 and for executing commands on a remote machine.
28 It provides secure encrypted communications between two untrusted
29 hosts over an insecure network. X11 connections and arbitrary TCP/IP
30 ports can also be forwarded over the secure channel.
31 It can be used to provide applications with a secure communication
32 channel.
33 .
34 This package provides the ssh, scp and sftp clients, the ssh-agent
35 and ssh-add programs to make public key authentication more convenient,
36 and the ssh-keygen, ssh-keyscan, ssh-copy-id and ssh-argv0 utilities.
37 .
38 In some countries it may be illegal to use any encryption at all
39 without a special permit.

13The Debian patch is distributed under the terms of the GPL, which you
14can find in /usr/share/common-licenses/GPL-2.
15
16In addition, as a special exception, Matthew Vernon gives permission
17to link the code of the Debian patch with any version of the OpenSSH
18code which is distributed under a license identical to that listed in
19the included Copyright file, and distribute linked combinations
20including the two. You must obey the GNU General Public License in
21all respects for all of the code used other than OpenSSH. If you

23file, but you are not obligated to do so. If you do not wish to do
24so, delete this exception statement from your version.

26The upstream source for this package is a combination of the ssh
27branch that is being maintained by the OpenBSD team (starting from
28the last version of SSH that was distributed under a free license),
29and porting work by Damien Miller <damien@ibs.com.au> to get it
30working on Linux. Other people also contributed to this, and are

1This package was debianized by Philip Hands <phil@hands.com> on 31 Oct 1999
2(with help from Dan Brosemer <odin@linuxfreak.com>)

10The Debian-specific parts of the package were initially derived from the
11original ssh package, which has since been renamed as ssh-nonfree.
12
13The Debian patch is distributed under the terms of the GPL, which you
14can find in /usr/share/common-licenses/GPL-2.
15
16In addition, as a special exception, Matthew Vernon gives permission
17to link the code of the Debian patch with any version of the OpenSSH
18code which is distributed under a license identical to that listed in
19the included Copyright file, and distribute linked combinations
20including the two. You must obey the GNU General Public License in
21all respects for all of the code used other than OpenSSH. If you
22modify this file, you may extend this exception to your version of the
23file, but you are not obligated to do so. If you do not wish to do
24so, delete this exception statement from your version.

26The upstream source for this package is a combination of the ssh
27branch that is being maintained by the OpenBSD team (starting from
28the last version of SSH that was distributed under a free license),
29and porting work by Damien Miller <damien@ibs.com.au> to get it
30working on Linux. Other people also contributed to this, and are
31credited in /usr/share/doc/ssh/README.

79OpenSSH provides end-to-end encrypted replacement of applications such as
80telnet, rlogin, and ftp.
81Unlike these legacy applications, OpenSSH never passes anything
82(including username and password) over the wire in unencrypted form, and
83provides host authentication, to verify that you really are talking to
84the system that you think you are and that no one else can take over
85that session.
86
87<p>
88The OpenSSH suite includes the
89<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a>
90program which replaces rlogin and telnet, and
91<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a>
92which replaces
93<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rcp&amp;sektion=1">rcp(1)</a> and
94<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ftp&amp;sektion=1">ftp(1)</a>.
95OpenSSH has also added
96<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> and
97<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a>
98which implement an easier solution for file-transfer. This is based upon the
99<a href="http://www.openssh.org/txt/draft-ietf-secsh-filexfer-02.txt">secsh-filexfer</a> IETF draft.
100
101
102<p><strong>OpenSSH consists of a number of programs.</strong>
103
104<ul>
105<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.
106Its behaviour is controlled by the config file <i><a
107href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
108sshd_config(5)</a></i>.
109<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.
110Its behaviour is controlled by the global config file <i><a
111href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
112ssh_config(5)</a></i> and individual users' <i>$HOME/.ssh/config</i> files.
113<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.
114<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).
115<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.
116<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.
117<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a> - SFTP server subsystem.
118<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> - Secure file transfer program.
119<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.
120<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.
121</ul>
122
123<h3>Downloading</h3>
124
125<p>
126The most recent version of OpenSSH is included with the current
127distribution of <a href="http://www.openbsd.org/">OpenBSD</a>, and
128installed as part of a basic install.
129
130<p>
131Today, most other operating systems include some version of OpenSSH
132(often re-badged or privately labeled), so most users can immediately
133use it.
134However, sometimes the included versions are quite old, and missing
135features of the current release of OpenSSH, and you may wish to install
136the current version, or install it on one of the few OSs that lacked it,
137and where the OS publisher does not make a modern version available.
138You may also wish to use OpenSSH on your embedded application.
139
140<p>
141Non-OpenBSD users will want to download, compile and install the
142multi-platform <a href="http://www.openssh.org/portable.html">Portable</a> distribution from a
143<a href="http://www.openssh.org/portable.html#mirrors">mirror</a> near you.
144
145
146<h2><a name= "1.2">1.2 - Why should it be used?</a></h2>
147
148<p>
149OpenSSH is a suite of tools to help secure your network
150connections. Here is a list of features:
151
152
153<ul>
154 <li>Strong authentication. Closes several security holes (e.g., IP, routing, and DNS spoofing).
155 <li>Improved privacy. All communications are automatically and transparently encrypted.
156 <li>Secure X11 sessions. The program automatically sets DISPLAY on the server machine, and forwards any X11 connections over the secure channel.
157 <li>Arbitrary TCP/IP ports can be redirected through the encrypted channel in both directions (e.g., for e-cash transactions).
158 <li>No retraining needed for normal users.
159 <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.
160 <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).
161 <li>Host authentication key distribution can be centrally by the administration, automatically when the first connection is made to a machine.
162 <li>Any user can create any number of user authentication RSA keys for his/her own use.
163 <li>The server program has its own server RSA key which is automatically regenerated every hour.
164 <li>An authentication agent, running in the user's laptop or local workstation, can be used to hold the user's RSA authentication keys.
165 <li>The software can be installed and used (with restricted functionality) even without root privileges.
166 <li>The client is customizable in system-wide and per-user configuration files.
167 <li>Optional compression of all data with gzip (including forwarded X11 and TCP/IP port data), which may result in significant speedups on slow connections.
168 <li>Complete replacement for rlogin, rsh, and rcp.
169</ul>
170
171<p>
172Currently, almost all communications in computer networks are done
173without encryption. As a consequence, anyone who has access to any
174machine connected to the network can listen in on any communication.
175This is being done by hackers, curious administrators, employers,
176criminals, industrial spies, and governments. Some networks leak off
177enough electromagnetic radiation that data may be captured even from a
178distance.
179
180
181<p>
182When you log in, your password goes in the network in plain
183text. Thus, any listener can then use your account to do any evil he
184likes. Many incidents have been encountered worldwide where crackers
185have started programs on workstations without the owner's knowledge
186just to listen to the network and collect passwords. Programs for
187doing this are available on the Internet, or can be built by a
188competent programmer in a few hours.
189
190
191<p>
192Businesses have trade secrets, patent applications in preparation,
193pricing information, subcontractor information, client data, personnel
194data, financial information, etc. Currently, anyone with access to
195the network (any machine on the network) can listen to anything that
196goes in the network, without any regard to normal access restrictions.
197
198
199<p>
200Many companies are not aware that information can so easily be
201recovered from the network. They trust that their data is safe
202since nobody is supposed to know that there is sensitive information
203in the network, or because so much other data is transferred in the
204network. This is not a safe policy.
205
206
207<h2><a name= "1.3">1.3 - What operating systems are supported?</a></h2>
208
209<p>
210Even though OpenSSH is developed on
211<a href="http://www.openbsd.org/">OpenBSD</a> a wide variety of
212ports to other operating systems exist. The portable version of OpenSSH
213is headed by <a href="mailto:djm@openbsd.org">Damien Miller</a>.
214For a quick overview of the portable version of OpenSSH see
215<a href="http://www.openssh.org/portable.html">OpenSSH Portable Release</a>.
216Currently, the supported operating systems are:
217
218
219<ul>
220 <li>OpenBSD
221 <li>NetBSD
222 <li>FreeBSD
223 <li>AIX
224 <li>HP-UX
225 <li>IRIX
226 <li>Linux
227 <li>NeXT
228 <li>SCO
229 <li>SNI/Reliant Unix
230 <li>Solaris
231 <li>Digital Unix/Tru64/OSF
232 <li>Mac OS X
233 <li>Cygwin
234</ul>
235
236<p>
237A list of vendors that include OpenSSH in their distributions
238is located in the <a href="http://www.openssh.org/users.html">OpenSSH Users page</a>.
239
240<h2><a name= "1.4">1.4 - What about copyrights, usage and patents?</a></h2>
241<p>
242The OpenSSH developers have tried very hard to keep OpenSSH free of any
243patent or copyright problems. To do this, some options had to be
244stripped from OpenSSH. Namely support for patented algorithms.
245
246<p>
247OpenSSH does not support any patented transport algorithms. In SSH1 mode,
248only 3DES and Blowfish are available options. In SSH2 mode, only 3DES,
249Blowfish, CAST128, Arcfour and AES can be selected.
250The patented IDEA algorithm is not supported.
251
252<p>
253OpenSSH provides support for both SSH1 and SSH2 protocols.
254
255<p>
256Since the RSA patent has expired, there are no restrictions on the use
257of RSA algorithm using software, including OpenBSD.
258
259<h2><a name= "1.5">1.5 - Where should I ask for help?</a></h2>

282
283<h2><a name= "2.1">2.1 - Why does ssh/scp make connections from low-numbered ports.</a></h2>
284<p>
285The OpenSSH client uses low numbered ports for rhosts and rhosts-rsa
286authentication because the server needs to trust the username provided by
287the client. To get around this, you can add the below example to your
288<i>ssh_config</i> or <i>~/.ssh/config</i> file.
289
290
291<blockquote>
292<table border=0 width="800">

315
316<h2><a name= "2.2">2.2 - Why is the ssh client setuid root?</a></h2>
317
318<p>
319In conjunction with the previous question, (<a href="#2.1">2.1</a>)
320OpenSSH needs root authority to be able to bind to low-numbered ports to
321facilitate <i>rhosts authentication</i>.
322A privileged port is also required for rhosts-rsa authentication to older
323SSH releases.
324
325<p>
326Additionally, for both <i>rhosts-rsa authentication</i> (in protocol
327version 1) and <i>hostbased authentication</i> (in protocol version 2)
328the ssh client needs to access the <i>private host key</i> in order to
329authenticate the client machine to the server.
330OpenSSH versions prior to 3.3 required the <code>ssh</code> binary to be
331setuid root to enable this, and you may safely remove it if you don't
332want to use these authentication methods.
333
334<p>
335Starting in OpenSSH 3.3, <code>ssh</code> is not setuid by default. <a
336href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign">ssh-keysign</a>,
337is used for access to the private hosts keys, and ssh does not use privileged
338source ports by default. If you wish to use a privileged source port, you must
339manually set the setuid bit on <code>ssh</code>.
340
341<h2><a name= "2.3">2.3 - Why does SSH 2.3 have problems interoperating with OpenSSH 2.1.1?</a></h2>
342
343<p>
344SSH 2.3 and earlier versions contain a flaw in their HMAC implementation.
345Their code was not supplying the full data block output from the digest,
346and instead always provided 128 bits. For longer digests, this caused
347SSH 2.3 to not interoperate with OpenSSH.
348
349<p>
350OpenSSH 2.2.0 detects that SSH 2.3 has this flaw. Recent versions of SSH
351will have this bug fixed. Or you can add the following to
352SSH 2.3 <i>sshd2_config</i>.

365<h2><a name= "2.4">2.4 - Why does OpenSSH print: Dispatch protocol error: type 20</a></h2>
366
367<p>
368Problems in interoperation have been seen because older versions of
369OpenSSH did not support session rekeying. However the commercial SSH 2.3
370tries to negotiate this feature, and you might experience connection
371freezes or see the error message &quot;<b>Dispatch protocol error:
372type 20 </b>&quot;.
373To solve this problem, either upgrade to a recent OpenSSH release or
374disable rekeying by adding the following to your commercial SSH 2.3's
375<i>ssh2_config</i> or <i>sshd2_config</i>.
376

416<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a>
417program contained a bug which caused it to occasionally generate Pubkey
418Authentication (RSA or DSA) keys which had their Most Significant Bit
419(MSB) unset. Such keys were advertised as being full-length, but are
420actually, half the time, smaller than advertised.
421
422<p>
423OpenSSH will print warning messages when it encounters such keys. To rid
424yourself of these message, edit your <i>known_hosts</i> files and replace the
425incorrect key length (usually "1024") with the correct key length
426(usually "1023").

428<h2><a name= "2.7">2.7 - X11 and/or agent forwarding does not work.</a></h2>
429

433enable it, put the line below in <i>sshd_config</i>:

458

462>xauth(1)</a> binary. On OpenBSD this is in the <i>xbase</i> file
463set but will probably be different on other platforms. For OpenSSH
464Portable, xauth must be either found at configure time or specified
465via <b>XAuthLocation</b> in sshd_config(5) and ssh_config(5).
466
467<p>
468Note on agent interoperability: There are two different and
469incompatible agent forwarding mechanisms within the SSH2 protocol.
470OpenSSH has always used an extension of the original SSH1 agent
471requests, however some commercial products use a different, non-free
472agent forwarding protocol. This means that agent forwarding cannot
473be used between OpenSSH and those products.

514
515<p>
516sftp and/or scp may fail at connection time if you have shell
517initialization (.profile, .bashrc, .cshrc, etc) which produces output
518for non-interactive sessions. This output confuses the sftp/scp client.
519You can verify if your shell is doing this by executing:
520
521<blockquote>
522<table border=0 width="800">
523 <tr>
524 <td nowrap bgcolor="#EEEEEE">
525<b>ssh yourhost /usr/bin/true</b>

529</blockquote>
530
531<p>
532If the above command produces any output, then you need to modify your
533shell initialization.
534
535<h2><a name= "2.10">2.10 - Will you add [foo] to scp?</a></h2>
536
537<p>
538Short Answer: no.
539
540<p>
541Long Answer: scp is not standardized. The closest thing it has to a
542specification is "what rcp does". Since the same command is used on both ends
543of the connection, adding features or options risks breaking interoperability with other
544implementations.
545
546<p>
547New features are more likely in sftp, since the protocol is standardized
548(well, a <a href="http://www.ietf.org/html.charters/OLD/secsh-charter.html">
549draft standard</a>), extensible, and the client and server are decoupled.
550
551<h2><a name= "2.11">2.11 - How do I use port forwarding?</a></h2>
552
553<p>
554If the remote server is running sshd(8), it may be possible to
555``tunnel'' certain services via ssh. This may be desirable, for
556example, to encrypt POP or SMTP connections, even though the software
557does not directly support encrypted communications. Tunnelling uses
558port forwarding to create a connection between the client and server.
559The client software must be able to specify a non-standard port to
560connect to for this to work.
561
562<p>
563The idea is that the user connects to the remote host using ssh,
564and specifies which port on the client's machine should be used to
565forward connections to the remote server. After that it is possible
566to start the service which is to be encrypted (e.g. fetchmail, irc)
567on the client machine, specifying the same local port passed to
568ssh, and the connection will be tunnelled through ssh. By default,
569the system running the forward will only accept connections from
570itself.
571
572<p>
573The options most relevant to tunnelling are the -L and -R options,
574which allow the user to forward connections, the -D option, which
575permits dynamic port forwarding, the -g option, which permits other
576hosts to use port forwards, and the -f option, which instructs ssh
577to put itself in the background after authentication. See the <a
578href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1"
579>ssh(1)</a> man page for further details.
580
581<p>
582This is an example of tunnelling an IRC session from client machine
583``127.0.0.1'' (localhost) to remote server ``server.example.com'':
584
585<blockquote>
586<table border=0 width="800">
587 <tr>
588 <td nowrap bgcolor="#EEEEEE">
589<b>ssh -f -L 1234:server.example.com:6667 server.example.com sleep 10<br>
590irc -c '#users' -p 1234 pinky 127.0.0.1</b>
591 </td>
592 </tr>
593</table>
594</blockquote>
595
596<p>
597This tunnels a connection to IRC server server.example.com, joining
598channel ``#users'', using the nickname ``pinky''. The local port used
599in this example is 1234. It does not matter which port is used, as
600long as it's greater than 1023 (remember, only root can open sockets on
601privileged ports) and doesn't conflict with any ports already in use.
602The connection is forwarded to port 6667 on the remote server, since
603that's the standard port for IRC services.
604
605<p>
606The remote command ``sleep 10'' was specified to allow an amount
607of time (10 seconds, in the example) to start the service which is to
608be tunnelled. If no connections are made within the time specified,
609ssh will exit. If more time is required, the sleep(1) value can be
610increased appropriately or, alternatively, the example above could
611be added as a function to the user's shell. See ksh(1) and csh(1)
612for more details about user-defined functions.
613
614<p>
615ssh also has an -N option, convenient for use with port forwarding:
616if -N is specified, it is not necessary to specify a remote command
617(``sleep 10'' in the example above). However, use of this option
618causes ssh to wait around for ever (as opposed to exiting after a
619remote command has completed), and the user must take care to manually
620kill(1) the process afterwards.
621
622<h2><a name= "2.12">2.12 - My ssh connection freezes or drops out after N minutes of inactivity.</a></h2>
623
624<p>
625This is usually the result of a packet filter or NAT device
626timing out your TCP connection due to inactivity. You can enable
627<b>ClientAliveInterval</b> in the server's <i><a
628href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
629sshd_config</a></i>, or enable <b>ServerAliveInterval</b> in the
630client's <i><a
631href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
632ssh_config</a></i> (the latter is available in OpenSSH 3.8 and newer).
633
634<p>
635Enabling either option and setting the interval for less than the time
636it takes to time out your session will ensure that the connection is
637kept "fresh" in the device's connection table.

669This information is used by clients and servers to enable protocol

681The portable version of OpenSSH will generate spurious authentication

692</table>
693</blockquote>
694
695<p>
696These are generated because OpenSSH first tries to determine whether a
697user needs authentication to login (e.g. empty password). Unfortunately
698PAM likes to log all authentication events, this one included.
699
700<p>
701If it annoys you too much, set &quot;<b>PermitEmptyPasswords no</b>&quot;
702in <i>sshd_config</i>. This will quiet the error message at the expense
703of disabling logins to accounts with no password set.
704This is the default if you use the supplied <i>sshd_config</i> file.
705
706<h2><a name= "3.2">3.2 - Empty passwords not allowed with PAM authentication.</a></h2>
707
708<p>
709To enable empty passwords with a version of OpenSSH built with PAM you
710must add the flag nullok to the end of the password checking module
711in the <i>/etc/pam.d/sshd</i> file. For example:
712
713<blockquote>
714<table border=0 width="800">
715 <tr>
716 <td nowrap bgcolor="#EEEEEE">
717auth required/lib/security/pam_unix.so shadow nodelay nullok
718 </td>
719 </tr>
720</table>
721</blockquote>
722
723<p>
724This must be done in addition to setting &quot;<b>PermitEmptyPasswords
725yes</b>&quot; in the <i>sshd_config</i> file.
726
727<p>
728There is one caveat when using empty passwords with PAM authentication:
729PAM will allow any password when authenticating an account with an empty
730password. This breaks the check that
731<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a>
732uses to determine whether an account has no password set and grant
733users access to the account regardless of the policy specified by
734<b>PermitEmptyPasswords</b>. For this reason, it is recommended that you
735do not add the <b>nullok</b> directive to your PAM configuration file
736unless you specifically wish to allow empty passwords.

750
751<li>There may be a DNS lookup problem, either at the client or server.
752You can use the <code>nslookup</code> command to check this on both client
753and server by looking up the other end's name and IP address. In
754addition, on the server look up the name returned by the client's

764<li>OpenSSH releases prior to 3.8 had an <i>moduli</i> file with

770manually).</li>
771
772<li>OpenSSH releases prior to 3.8 had a flaw in <code>ssh</code> that
773would cause it to request moduli larger than intended (which when

801<h3>How slow is "slow"?</h3>
802Under normal conditions, the speed of SSH logins is dependant on
803CPU speed of client and server. For comparison the following are
804typical connect times for <code>time ssh localhost true</code>
805with a 1024-bit RSA key on otherwise unloaded hosts. OpenSSH and
806OpenSSL were compiled with gcc 3.3.x.

833
834<p>
835The Linux kernel is looking (via modprobe) for protocol family 10 (IPv6).
836Either load the appropriate kernel module, enter the correct alias in
837<i>/etc/modules.conf</i> or disable IPv6 in <i>/etc/modules.conf</i>.
838

845<h2><a name= "3.5">3.5 - Password authentication doesn't work (eg on Slackware 7.0 or Red Hat 6.x)</a></h2>
846
847<p>
848If the password is correct password the login is still denied, the
849usual cause is that the system is configured to use MD5-type passwords
850but the
851<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=crypt&amp;sektion=3"
852>crypt(3)</a> function used by sshd doesn't understand them.
853
854<p>
855Affected accounts will have password strings in <i>/etc/passwd</i>
856or <i>/etc/shadow</i> that start with <b>$1$</b>.
857If password authentication fails for new accounts or accounts with
858recently changed passwords, but works for old accounts, this is the
859likely culprit.
860
861<p>
862The underlying cause is that some versions of OpenSSL have a crypt(3)
863function that does not understand MD5 passwords, and the link order of
864sshd means that OpenSSL's crypt(3) is used instead of the system's.
865OpensSSH's configure attempts to correct for this but is not always
866successful.
867
868<p>
869There are several possible solutions:
870
871<ul>
872<li>
873<p>
874Enable sshd's built-in support for MD5 passwords at build time.
875
876<blockquote>

879 <td nowrap bgcolor="#EEEEEE">
880./configure --with-md5-passwords [options]
881 </td>
882 </tr>
883</table>
884</blockquote>
885
886This is safe even if you have both types of encryption as sshd will
887select the correct algorithm for each account automatically.
888
889<li>
890<p>
891If your system has a separate libcrypt library (eg Slackware 7) then you
892can manually add -lcrypt to the LIBS list so it's used instead of
893OpenSSL's:
894
895<blockquote>
896<table border=0 width="800">
897 <tr>
898 <td nowrap bgcolor="#EEEEEE">

900 </td>
901 </tr>
902</table>
903</blockquote>
904
905<li>
906<p>
907If your platforms supports PAM, you may configure sshd to use it
908(see <a href= "#3.15" >section 3.15</a>). This will mean that sshd will
909not verify passwords itself but will defer to the configured PAM modules.
910</ul>
911
912<h2><a name= "3.6">3.6 - Configure or sshd(8) complain about lack of RSA or DSA support</a></h2>

923must be in the default PATH on both the client and the server. You may
924need to use the <b>--with-default-path</b> option to specify a custom
925path to search on the server. This option replaces the default path,
926so you need to specify all the current directories on your path as well
927as where you have installed scp. For example:
928
929<blockquote>
930<table border=0 width="800">
931 <tr>

934 </td>
935 </tr>
936</table>
937</blockquote>
938
939<p>
940Note that configuration by the server's admin will take precedence over the
941setting of <b>--with-default-path</b>. This includes resetting PATH in
942<i>/etc/profile</i>, PATH in <i>/etc/environment</i> on AIX, or (for 3.7p1 and
943above) setting PATH or SUPATH in <i>/etc/default/login</i> on Solaris or
944Reliant Unix.
945
946<h2><a name= "3.8">3.8 - Unable to read passphrase</a></h2>
947
948<p>
949Some operating systems set <i>/dev/tty</i> with incorrect modes, causing
950the reading of passwords to fail with the following error:
951
952<blockquote>
953<table border=0 width="800">

957 </td>
958 </tr>
959</table>
960</blockquote>
961
962<p>
963The solution to this is to reset the permissions on <i>/dev/tty</i>
964to mode 0666 and report the error as a bug to your OS vendor.

972downloaded the OpenBSD distribution of OpenSSH and are attempting to
973compile it on another platform. Please refer to the information on the

978
979<p>
980OpenSSH may hang when exiting. This can occur when there is an active
981background process. This is known to occur on Linux and HP-UX.
982The problem can be verified by doing the following:
983
984<blockquote>
985<table border=0 width="800">
986 <tr>
987 <td nowrap bgcolor="#EEEEEE">

1001 </tr>
1002</table>
1003</blockquote>
1004
1005<p>
1006A work around for bash users is to place <b>"shopt -s huponexit"</b>
1007in either /etc/bashrc or ~/.bashrc. Otherwise, consult your shell's
1008man page for an option to enable it to send a HUP signal to active
1009jobs when exiting. See <a

1046with this configuration.<p>
1047
1048In general, X11 clients using X11 R6 should work with the default
1049setting. Some vendors, including HP, ship X11 clients with R6
1050and R5 libs, so some clients will work, and others will not work.
1051This is true for HP-UX 11.X.<p>
1052
1053<h2><a name= "3.13">3.13 - I upgraded to OpenSSH 3.8 and some

1071
1072<p>
1073Typically this is caused by the file permissions on $HOME, $HOME/.ssh or
1074$HOME/.ssh/authorized_keys being more permissive than sshd allows by default.
1075
1076<p>
1077In this case, it can be solved by executing the following on the server.

1091If this is not possible for some reason, an alternative is to set

1110
1111To use PAM at all, this option must be provided at build time.
1112The run-time behaviour when PAM is built in varies with the version of
1113Portable OpenSSH, and on later versions it must also be enabled by setting
1114<b>UsePAM</b> to <b>yes</b> in <i>sshd_config</i>.
1115
1116<p>
1117The behaviour of the relevant authentications options when PAM support is built
1118in is summarised by the following table.

1156OpenSSH Portable's PAM interface still has problems with a few modules,

1174
1175Between AIX 4.3.3 and AIX 5.x, the format of the wtmp struct changed. This
1176means that sshd binaries built on AIX 4.x will not correctly write wtmp
1177entries when run on AIX 5.x. This can be fixed by simply recompiling
1178sshd on an AIX 5.x system and using that.

1.TH GNOME-SSH-ASKPASS 1
2.SH NAME
3gnome\-ssh\-askpass \- prompts a user for a passphrase using GNOME
4.SH SYNOPSIS
5.B gnome\-ssh\-askpass
6.SH DESCRIPTION
7.B gnome\-ssh\-askpass
8is a GNOME-based passphrase dialog for use with OpenSSH.
9It is intended to be called by the
10.BR ssh\-add (1)
11program and not invoked directly.
12It allows
13.BR ssh\-add (1)
14to obtain a passphrase from a user, even if not connected to a terminal
15(assuming that an X display is available).
16This happens automatically in the case where
17.B ssh\-add
18is invoked from one's
19.B ~/.xsession
20or as one of the GNOME startup programs, for example.
21.PP
22In order to be called automatically by
23.BR ssh\-add ,
24.B gnome\-ssh\-askpass
25should be installed as
26.IR /usr/bin/ssh\-askpass .
27.SH "ENVIRONMENT VARIABLES"
28The following environment variables are recognized:
29.TP
30.I GNOME_SSH_ASKPASS_GRAB_SERVER
31Causes
32.B gnome\-ssh\-askpass
33to grab the X server before asking for a passphrase.
34.TP
35.I GNOME_SSH_ASKPASS_GRAB_POINTER
36Causes
37.B gnome\-ssh\-askpass
38to grab the mouse pointer using
39.IR gdk_pointer_grab ()
40before asking for a passphrase.
41.PP
42Regardless of whether either of these environment variables is set,
43.B gnome\-ssh\-askpass
44will grab the keyboard using
45.IR gdk_keyboard_grab ().
46.SH AUTHOR
47This manual page was written by Colin Watson <cjwatson@debian.org>
48for the Debian system (but may be used by others).
49It was based on that for
50.B x11\-ssh\-askpass

1Template: openssh-server/permit-root-login
2Type: boolean
3Default: false
4_Description: Disable SSH password authentication for root?
5 Previous versions of openssh-server permitted logging in as root over SSH
6 using password authentication. The default for new installations is now
7 "PermitRootLogin prohibit-password", which disables password authentication
8 for root without breaking systems that have explicitly configured SSH
9 public key authentication for root.
10 .
11 This change makes systems more secure against brute-force password
12 dictionary attacks on the root user (a very common target for such
13 attacks). However, it may break systems that are set up with the
14 expectation of being able to SSH as root using password authentication. You
15 should only make this change if you do not need to do that.

4Subject: GSSAPI key exchange support
5
6This patch has been rejected upstream: "None of the OpenSSH developers are
7in favour of adding this, and this situation has not changed for several
8years. This is not a slight on Simon's patch, which is of fine quality, but
9just that a) we don't trust GSSAPI implementations that much and b) we don't
10like adding new KEX since they are pre-auth attack surface. This one is
11particularly scary, since it requires hooks out to typically root-owned
12system resources."
13
14However, quite a lot of people rely on this in Debian, and it's better to
15have it merged into the main openssh package rather than having separate
16-krb5 packages (as we used to have). It seems to have a generally good
17security history.

4Subject: Various keepalive extensions
5
6Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported
7in previous versions of Debian's OpenSSH package but since superseded by
8ServerAliveInterval. (We're probably stuck with this bit for
9compatibility.)
10
11In batch mode, default ServerAliveInterval to five minutes.
12
13Adjust documentation to match and to give some more advice on use of
14keepalives.

4Subject: Don't check the status field of the OpenSSL version
5
6There is no reason to check the version of OpenSSL (in Debian). If it's
7not compatible the soname will change. OpenSSH seems to want to do a
8check for the soname based on the version number, but wants to keep the
9status of the release the same. Remove that check on the status since
10it doesn't tell you anything about how compatible that version is.

4Subject: Reduce severity of "Killed by signal %d"
5
6This produces irritating messages when using ProxyCommand or other programs
7that use ssh under the covers (e.g. Subversion). These messages are more
8normally printed by the calling program, such as the shell.
9
10According to the upstream bug, the right way to avoid this is to use the -q
11option, so we may drop this patch after further investigation into whether
12any software in Debian is still relying on it.

4Subject: Restore TCP wrappers support
5
6Support for TCP wrappers was dropped in OpenSSH 6.7. See this message
7and thread:
8
9 https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-April/032497.html
10
11It is true that this reduces preauth attack surface in sshd. On the
12other hand, this support seems to be quite widely used, and abruptly
13dropping it (from the perspective of users who don't read
14openssh-unix-dev) could easily cause more serious problems in practice.
15
16It's not entirely clear what the right long-term answer for Debian is,
17but it at least probably doesn't involve dropping this feature shortly
18before a freeze.

4Subject: Adjust scp quoting in verbose mode
5
6Tweak scp's reporting of filenames in verbose mode to be a bit less
7confusing with spaces.

9This should be revised to mimic real shell quoting.

4Subject: Handle SELinux authorisation roles

6Old versions of OpenSSH (up to 2.5 or thereabouts) allowed creating symlinks
7to ssh with the name of the host you want to connect to. Debian ships an
8ssh-argv0 script restoring this feature; this patch refers to its manual

6These options were used as part of Debian's response to CVE-2008-0166.
7Nearly six years later, we no longer need to continue carrying the bulk
8of that patch, but we do need to avoid failing when the associated

4Subject: "LogLevel SILENT" compatibility
5
6"LogLevel SILENT" (-qq) was introduced in Debian openssh 1:3.0.1p1-1 to
7match the behaviour of non-free SSH, in which -q does not suppress fatal
8errors. However, this was unintentionally broken in 1:4.6p1-2 and nobody
9complained, so we've dropped most of it. The parts that remain are basic
10configuration file compatibility, and an adjustment to "Pseudo-terminal will
11not be allocated ..." which should be split out into a separate patch.

4Subject: Allow harmless group-writability
5
6Allow secure files (~/.ssh/config, ~/.ssh/authorized_keys, etc.) to be
7group-writable, provided that the group in question contains only the file's
8owner. Rejected upstream for IMO incorrect reasons (e.g. a misunderstanding
9about the contents of gr->gr_mem). Given that per-user groups and umask 002
10are the default setup in Debian (for good reasons - this makes operating in
11setgid directories with other groups much easier), we need to permit this by
12default.

42.Nm
43replaces the old ssh command-name as hostname handling.
44If you link to this script with a hostname then executing the link is
45equivalent to having executed ssh with that hostname as an argument.
46All other arguments are passed to ssh and will be processed normally.

1This package contains a Gnome based implementation of ssh-askpass
2written by Damien Miller.
3
4It is split out from the main package to isolate the dependency on the
5Gnome and X11 libraries.
6
7It was packaged for Debian by Philip Hands <phil@hands.com>.

1ssh-krb5 (1:4.3p2-7) unstable; urgency=low
2
3 The normal openssh-server and openssh-client packages in Debian now
4 include full GSSAPI support, including key exchange. This package is
5 now only a transitional package that depends on openssh-server and
6 openssh-client and configures openssh-server for GSSAPI authentication
7 if it wasn't already.
8
9 You can now simply install openssh-server and openssh-client directly
10 and remove this package. Just make sure that /etc/ssh/sshd_config
11 contains:
12
13 GSSAPIAuthentication yes
14 GSSAPIKeyExchange yes
15
16 if you want to support GSSAPI authentication to your ssh server.
