Both default to "yes"; to disable + keepalives, set the value to "no" in both the server and the + client configuration files. Updated manual pages. + + * sshd.c: Fixed Solaris utmp problem: wrong pid stored in utmp + (patch from Petri Virkkula <argon@bat.cs.hut.fi>). + + * login.c (record_logout): Fixed removing user from utmp on BSD + (with HAVE_LIBUTIL_LOGIN). + + * Added cleanup functions to be called from fatal(). Arranged for + utmp to be cleaned if sshd terminates by calling fatal (e.g., + after dropping connection). Eliminated separate client-side + fatal() functions and moved fatal() to log-client.c. Made all + cleanups, including channel_stop_listening() and packet_close() + be called using this mechanism. + +Thu Nov 9 09:58:05 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * sshd.c: Permit immediate login with empty password only if + password authentication is allowed. + +Wed Nov 8 00:43:55 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * Eliminated unix-domain X11 forwarding. Inet-domain forwarding is + now the only supported form. Renamed server option + X11InetForwarding to X11Forwarding, and eliminated + X11UnixForwarding. Updated documentation. Updated RFC (marked + the SSH_CMSG_X11_REQUEST_FORWARDING message (code 26) as + obsolete, and removed all references to it). Increased protocol + version number to 1.3. + + * scp.c (main): Added -B (BatchMode). Updated manual page. + + * Cleaned up and updated all manual pages. + + * clientloop.c: Added new escape sequences ~# (lists forwarded + connections), ~& (background ssh when waiting for forwarded + connections to terminate), ~? (list available escapes). + Polished the output of the connection listing. Updated + documentation. + + * uidswap.c: If _POSIX_SAVED_IDS is defined, don't change the real + uid. Assume that _POSIX_SAVED_IDS also applies to seteuid. + This may solve problems with tcp_wrappers (libwrap) showing + connections as coming from root. + +Tue Nov 7 20:28:57 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * Added RandomSeed server configuration option. The argument + specifies the location of the random seed file. Updated + documentation. + + * Locate perl5 in configure. Generate make-ssh-known-hosts (with + the correct path for perl5) in Makefile.in, and install it with + the other programs. Updated manual page. + + * sshd.c (main): Added a call to umask to set the umask to a + reasonable value. + + * compress.c (buffer_compress): Fixed to follow the zlib + documentation (which is slightly confusing). + + * INSTALL: Added information about Linux libc.so.4 problem. + +Mon Nov 6 15:42:36 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * (Actually autoconf fix) Installed patch to AC_ARG_PROGRAM. + + * sshd.c, sshd.8.in: Renamed $HOME/.environment -> + $HOME/.ssh/environment. + + * configure.in: Disable shadow password checking on convex. + Convex has /etc/shadow, but sets pw_passwd automatically if + running as root. + + * Eliminated HAVE_ETC_MASTER_PASSWD (NetBSD, FreeBSD); the + pw_passwd field is automatically filled if running as root. + Put explicit code in configure.in to prevent shadow password + checking on FreeBSD and NetBSD. + + * serverloop.c (signchld_handler): Don't print error if wait + returns -1. + + * Makefile.in (install): Fixed modes of data files. + + * Makefile.in (install): Make links for slogin.1. + + * make-ssh-known-hosts: Merged a patch from melo@ci.uminho.pt to + fix the ping command. + +Fri Nov 3 16:25:28 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * ssh.1.in: Added more information about X11 forwarding. + +Thu Nov 2 18:42:13 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * Changes to use O_NONBLOCK_BROKEN consistently. + + * pty.c (pty_make_controlling_tty): Use setpgid instead of + setsid() on Ultrix. + + * includes.h: Removed redundant #undefs for Ultrix and Sony News; + these are already handled in configure.in. + +Tue Oct 31 13:31:28 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * configure.in: Define SSH_WTMP to /var/adm/wtmp is wtmp not found. + + * configure.in: Disable vhangup on Ultrix. I am told this fixes + the server problems. + +Sat Oct 28 14:22:05 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * sshconnect.c: Fixed a bug in connecting to a multi-homed host. + Restructured the connecting code to never try to use the same + socket a second time after a failed connection. + + * Makefile.in: Added explicit -m option to install, and umask 022 + when creating directories and the host key. + +Fri Oct 27 01:05:10 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * Makefile.in: Added cleaning of $(ZLIBDIR) to clean and distclean. + + * login.c (get_last_login_time): Fixed a typo (define -> defined). + +Thu Oct 26 01:28:07 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * configure.in: Moved testing for ANSI C compiler after the host + specific code (problems on HPUX). + + * Minor fixes to /etc/default/login stuff from Bryan O'Sullivan. + + * Fixed .SH NAME sections in manual pages. + + * compress.c: Trying to fix a mysterious bug in the compression + glue. + + * ssh-1.2.11. + + * scp.c: disable agent forwarding when running ssh from scp. + + * Added compression of plaintext packets using the gzip library + (zlib). Client configuration options Compression and + CompressionLevel (1-9 as in gzip). New ssh and scp option -C + (to enable compression). Updated RFC. + +Wed Oct 25 05:11:55 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * Implemented ProxyCommand stuff based on patches from Bryan + O'Sullivan <bos@serpentine.com>. + + * Merged BSD login/logout/lastlog patches from Mark Treacy + <mark@labtam.oz.au>. + + * sshd.c: Added chdir("/"). + +Tue Oct 24 00:29:01 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * Merged RSA environment= patches from Felix Leitner + <leitner@prz.tu-berlin.de> with some changes. + + * sshd.c: Made the packet code use two separate descriptors for + the connection (one for input, the other for output). This will + make future extensions easier (e.g., non-socket transports, etc.). + sshd -i now uses both stdin and stdout separately. + +Mon Oct 23 21:29:28 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * sshd.c: Merged execle -> execve patches from Mark Martinec + <Mark.Martinec@nsc.ijs.si>. This may help with execle bugs on + Convex (environment not getting passed properly). This might + also solve similar problems on Sonys; please test! + + * Removed all compatibility code for protocol version 1.0. + THIS MEANS THAT WE ARE NO LONGER COMPATIBLE WITH SSH VERSIONS + PRIOR TO 1.1.0. + + * randoms.c (random_acquire_light_environmental_noise): If + /dev/random is available, read up to 32 bytes (256 bits) from + there in non-blocking mode, and mix the new random bytes into + the pool. + + * Added client configuration option StrictHostKeyChecking + (disabled by default). If this is enabled, the client will not + automatically add new host keys to $HOME/.ssh/known_hosts; + instead the connection will be refused if the host key is not + known. Similarly, if the host key has changed, the connection + will be refused instead if just issuing a warning. This + provides additional security against man-in-the-middle/trojan + horse attacks (especially in scripts where there is no-one to + see the warnings), but may be quite inconvenient in everyday + interactive use unless /etc/ssh_known_hosts is very complete, + because new host keys must now be added manually. + + * sshconnect.c (ssh_connect): Use the user's uid when creating the + socket and connecting it. I am hoping that this might help with + tcp_wrappers showing the remote user as root. + + * ssh.c: Try inet-domain X11 forwarding regardless of whether we + can get local authorization information. If we don't, we just + come up with fake information; the forwarding code will anyway + generate its own fake information and validate that the client + knows that information. It will then substitute our fake + information for that, but that info should get ignored by the + server if it doesn't support it. + + * Added option BatchMode to disable password/passphrase querying + in scripts. + + * auth-rh-rsa.c: Changed to use uid-swapping when reading + .ssh/known_hosts. + + * sshd.8.in (command): Improved documentation of file permissions + on the manual pages. + +Thu Oct 19 21:05:51 1995 Tatu Ylonen <ylo@soikko.cs.hut.fi> + + * ssh-add.c (add_file): Fixed a bug causing ssh to sometimes refer + to freed memory (comment -> saved_comment). + + * log-server.c: Added a prefix to debug/warning/error/fatal + messages describing message types. Syslog does not include that + information automatically. + +Sun Oct 8 01:56:01 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Merged /etc/default/login and MAIL environment variable changes + from Bryan O'Sullivan <bos@serpentine.com>. + - mail spool file location + - process /etc/default/login + - add HAVE_ETC_DEFAULT_LOGIN + - new function child_get_env and read_etc_default_login (sshd.c) + + * ssh-add.c (add_file): Fixed asking for passphrase. + + * Makefile.in: Fixed installing configure-generated man pages when + compiling in a separate object directory. + + * sshd.c (main): Moved RSA key generation until after allocating + the port number. (Actually, the code got duplicated because we + never listen when run from inetd.) + + * ssh.c: Fixed a problem that caused scp to hang when called with + stdin closed. + +Sat Oct 7 03:08:06 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Added server config option StrictModes. It specifies whether to + check ownership and modes of home directory and .rhosts files. + + * ssh.c: If ssh is renamed/linked to a host name, connect to that + host. + + * serverloop.c, clientloop.c: Ignore EAGAIN reported on read from + connection. Solaris has a kernel bug which causes select() to + sometimes wake up even though there is no data available. + + * Display all open connections when printing the "Waiting for + forwarded connections to terminate" message. + + * sshd.c, readconf.c: Added X11InetForwarding and + X11UnixForwarding server config options. + +Thu Oct 5 17:41:16 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Some more SCO fixes. + +Tue Oct 3 01:04:34 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Fixes and cleanups in README, INSTALL, COPYING. + +Mon Oct 2 03:36:08 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * ssh-add.c (add_file): Fixed a bug in ssh-add (xfree: NULL ...). + + * Removed .BR from ".SH NAME" in man pages. + +Sun Oct 1 04:16:07 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * ssh-1.2.10. + + * configure.in: When checking that the compiler works, check that + it understands ANSI C prototypes. + + * Made uidswap error message a debug() to avoid confusing errors + on AIX (AIX geteuid is brain-damaged and fails even for root). + + * Fixed an error in sshd.8 (FacistLogging -> FascistLogging). + + * Fixed distribution in Makefile.in (missing manual page .in files). + +Sat Sep 30 17:38:46 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * auth-rhosts.c: Fixed serious security problem in + /etc/hosts.equiv authentication. + +Fri Sep 29 00:41:02 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Include machine/endian.h on Paragon. + + * ssh-add.c (add_file): Made ssh-add keep asking for the + passphrase until the user just types return or cancels. + Make the dialog display the comment of the key. + + * Read use shosts.equiv in addition to /etc/hosts.equiv. + + * sshd.8 is now sshd.8.in and is processed by configure to + substitute the proper paths for various files. Ditto for ssh.1. + Ditto for make-ssh-known-hosts.1. + + * configure.in: Moved /etc/sshd_pid to PIDDIR/sshd.pid. PIDDIR + will be /var/run if it exists, and ETCDIR otherwise. + +Thu Sep 28 21:52:42 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * On Ultrix, check if sys/syslog.h needs to be included in + addition to syslog.h. + + * make-ssh-known-hosts.pl: Merged Kivinen's fixes for HPUX. + + * configure.in: Put -lwrap, -lsocks, etc. at the head of LIBS. + + * Fixed case-insensitivity in auth-rhosts.c. + + * Added missing socketpair.c to EXTRA_SRCS (needed on SCO), plus + other SCO fixes. + + * Makefile.in: Fixed missing install_prefixes. + +Wed Sep 27 03:57:00 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * ssh-1.2.9. + + * Added SOCKS support. + + * Fixed default setting of IgnoreRhosts option. + + * Pass the magic cookie to xauth in stdin instead of command line; + the command line is visible in ps. + + * Added processing $HOME/.ssh/rc and /etc/sshrc. + + * Added a section to sshd.8 on what happens at login time. + +Tue Sep 26 01:27:40 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Don't define speed_t on SunOS 4.1.1; it conflicts with system + headers. + + * Added support for .hushlogin. + + * Added --with-etcdir. + + * Read $HOME/.environment after /etc/environment. + +Mon Sep 25 03:26:06 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Merged patches for SCO Unix (from Michael Henits). + +Sun Sep 24 22:28:02 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Added ssh option ConnectionAttempts. + +Sat Sep 23 12:30:15 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * sshd.c: Don't print last login time and /etc/motd if a command + has been specified (with ssh -t host command). + + * Added support for passing the screen number in X11 forwarding. + It is implemented as a compatible protocol extension, signalled + by SSH_PROTOFLAG_SCREEN_NUMBER by the child. + + * clientloop.c: Fixed bugs in the order in which things were + processed. This may solve problems with some data not getting + sent to the server as soon as possible (probably solves the TCP + forwarding delayed close problem). Also, it looked like window + changes might not get transmitted as early as possible in some + cases. + + * clientloop.c: Changed to detect window size change that + happened while ssh was suspended. + + * ssh.c: Moved the do_session function (client main loop) to + clientloop.c. Divided it into smaller functions. General cleanup. + + * ssh-1.2.8 + +Fri Sep 22 22:07:46 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * sshconnect.c (ssh_login): Made ssh_login take the options + structure as argument, instead of the individual arguments. + + * auth-rhosts.c (check_rhosts_file): Added support for netgroups. + + * auth-rhosts.c (check_rhosts_file): Added support for negated + entries. + +Thu Sep 21 00:07:56 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * auth-rhosts.c: Restructured rhosts authentication code. + Hosts.equiv now has same format as .rhosts: user names are allowed. + + * Added support for the Intel Paragon. + + * sshd.c: Don't use X11 forwarding with spoofing if no xauth + program. Changed configure.in to not define XAUTH_PATH if + there is no xauth program. + + * ssh-1.2.7 + + * sshd.c: Rewrote the code to build the environment. Now also reads + /etc/environment. + + * sshd.c: Fixed problems in libwrap code. --with-libwrap now + takes optional library name/path. + + * ssh-1.2.6 + + * Define USE_PIPES by default. + + * Added support for Univel Unixware and MachTen. + + * Added IgnoreRhosts server option. + + * Added USE_STRLEN_FOR_AF_UNIX; it is needed at least on MachTen. + +Wed Sep 20 02:41:02 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * sshd.c (do_child): don't call packet_close when /etc/nologin, + because packet_close does shutdown, and the message does not get + sent. + + * pty.c (pty_allocate): Push ttcompat streams module. + + * randoms.c (random_acquire_light_environmental_noise): Don't use + the second argument to gettimeofday as it is not supported on + all systems. + + * login.c (record_login): Added NULL second argument to gettimeofday. + +Tue Sep 19 13:25:48 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * fixed pclose wait() in sshd key regeneration (now only collects + easily available noise). + + * configure.in: test for bsdi before bsd*. + + * ssh.c: Don't print "Connection closed" if -q. + +Wed Sep 13 04:19:52 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Released ssh-1.2.5. + + * Hopefully fixed "Waiting for forwarded connections to terminate" + message. + + * randoms.c, md5.c: Large modifications to make these work on Cray + (which has no 32 bit integer type). + + * Fixed a problem with forwarded connection closes not being + reported immediately. + + * ssh.c: fixed rhosts authentication (broken by uid-swapping). + + * scp.c: Don't use -l if server user not specified (it made + setting User in the configuration file not work). + + * configure.in: don't use -pipe on BSDI. + + * randoms.c: Major modifications to make it work without 32 bit + integers (e.g. Cray). + + * md5.c: Major modifications to make it work without 32 bit + integers (e.g. Cray). + + * Eliminated HPSUX_BROKEN_PTYS. The code is now enabled by + default on all systems. + +Mon Sep 11 00:53:12 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * sshd.c: don't include sshd pathname in log messages. + + * Added libwrap stuff (includes support for identd). + + * Added OSF/1 C2 extended security stuff. + + * Fixed interactions between getuid() and uid-swap stuff. + +Sun Sep 10 00:29:27 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * serverloop.c: Don't send stdout data to client until after a few + milliseconds if there is very little data. This is because some + systems give data from pty one character at a time, which would + multiply data size by about 16. + + * serverloop.c: Moved server do_session to a separate file and + renamed it server_loop. Split it into several functions and + partially rewrote it. Fixed "cat /etc/termcap | ssh foo cat" hangup. + + * Screwed up something while checking stuff in under cvs. No harm, + but bogus log entries... + +Sat Sep 9 02:24:51 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * minfd.c (_get_permanent_fd): Use SHELL environment variable. + + * channels.c (x11_create_display_inet): Created + HPSUX_NONSTANDARD_X11_KLUDGE; it causes DISPLAY to contain the + IP address of the host instead of the name, because HPSUX uses + some magic shared memory communication for local connections. + + * Changed SIGHUP processing in server; it should now work multiple + times. + + * Added length limits in many debug/log/error/fatal calls just in + case. + + * login.c (get_last_login_time): Fixed location of lastlog. + + * Rewrote all uid-swapping code. New files uidswap.h, uidswap.c. + + * Fixed several security problems involving chmod and chgrp (race + conditions). Added warnings about dubious modes for /tmp/.X11-unix. + +Fri Sep 8 20:03:36 1995 Tatu Ylonen <ylo@shadows.cs.hut.fi> + + * Changed readconf.c to never display anything from the config + file. This should now be prevented otherwise, but let's play safe. + + * log-server.c: Use %.500s in syslog() just to be sure (they + should already be shorter than 1024 though). + + * sshd.c: Moved setuid in child a little earlier (just to be + conservative, there was no security problem that I could detect). + + * README, INSTALL: Added info about mailing list and WWW page. + + * sshd.c: Added code to use SIGCHLD and wait zombies immediately. + + * Merged patch to set ut_addr in utmp. + + * Created ChangeLog and added it to Makefile.in. + + * Use read_passphrase instead of getpass(). + + * Added SSH_FALLBACK_CIPHER. Fixed a bug in default cipher + selection (IDEA used to be selected even if not supported by the + server). + + * Use no encryption for key files if empty passphrase. + + * Added section about --without-idea in INSTALL. + + * Version 1.2.0 was released a couple of days ago. + |
