Sat Jan  3 07:11:58 1998  Tero Kivinen  <kivinen@ssh.fi>

        * Fixed bug in {Allow,Deny}ForwardingTo host name handling. The
        host name was not nul terminated properly. 
        
        * Added {Allow,Deny}groups patch from Jason Ackley
        <jason@viaccess.net>.

Fri Jan  2 04:51:21 1998  Tero Kivinen  <kivinen@ssh.fi>

        * (F-SECURE): Added support for {Allow,Deny}Forwarding{To,Port}
        options in authorized_keys file.
        
        * Fixed ssh-agent dying when it received SIGPIPE when user
        pressed Ctrl-C in middle of login process. 
        
        * Changed authorized_keys file options to be case insensitive. 
        
        * Confirmed that ssh is Y2K compliant. The HAVE_USERSEC_H code in
        login_permitted function in sshd.c file is the only code that has
        some Y2K problems. The expiration format returned by getuserattr
        is only yymmddhhmm, and when login_permitted converts it to
        normalized format that assumes that if yy < 70 then it must be
        20yy, otherwise assume it to be 19yy. This means that you cannot
        now have users whose account expires after year 2070.

        * Confirmed that on enviroments where time_t is 32 bit unsigned
        long or 64 bit value ssh should also be Y2038 complient.
        
        * GMP configure patch for FreeBSD/ELF system from Ollivier Robert
        <reberto@keltia.freenix.fr>.
        
        * Added CheckMail patch from Aaron Gowatch <aarong@wired.com>. 
        
        * Added patch from Nick Nibma <nick.hibma@jrc.it> that will change
        password from from "foo's password" to foo@bar's password.
        
        * Implemented -k option for ssh-agent (kill agent) suggested by
        Charles M. Hannum <mycroft@mit.edu>

        * Fixed agent socket opening code for suid versions.
        
        * Renamed SSH_AUTHENCATION_SOCKET to SSH_AUTH_SOCK, because some
        environments have limit for environment variable lengths. 
        
        * Added XAuthLocation and kerberos 5 patch from Harry G. McGavran
        Jr. <hgm@lanl.gov>.
        
        * Added OSF C2 user account locked and expired checks and user
        default resource limits patch from Joao Castro
        <jcastro@ist.utl.pt>.
        
        * Adde BSDI /etc/login.conf and password expiration warning
        patches from Jason Ackley <jason@ackley.net>.
        
Mon Apr 28 00:53:04 1997  Tero Kivinen  <kivinen@ssh.fi>

        * (F-SECURE): Added {Allow,Deny}Forwarding{To,Port} feature. 
        
        * Added {Allow,Deny}Users feature from Steve Kann
        <stevek@SteveK.COM>.

Wed Apr 23 02:56:20 1997  Tero Kivinen  <kivinen@ssh.fi>

        * scp: Added -oClearAllForwardings yes to ssh command line, so if
        you have forwardings in config file you can still use scp without
        errors because ssh cannot bind those same sockets. 
        
        * Added ClearAllForwardings and NumberOfPasswordPrompts options.
        
        * Fixed SIGINFO check.

        * Added check that getpseudotty function exists before using, we
        cannot assume it exists if /dev/getpty exists, because some dynix
        systems have /dev/getpty but no getpseudotty function.
        
        * Added check that spwd struct have sp_expire and sp_inact fields.
                
        * Added WRAPLIBS to Makefile.in and configure.in so libwrap is
        linked to only ssh and sshd.

Mon Apr 21 05:47:46 1997  Tero Kivinen  <kivinen@ssh.fi>

        * Added -S option to scp (specifies path to ssh program).
        
        * Added waitpid loop to main_sigchld_handler if we have it.
        
        * Changed server_loop to call pty_cleanup_proc instead of
        pty_release, added check to pty_cleanup_proc so it will not
        cleanup pty twice.
        
        * Fixed allow_tcp_forwarding option so it defaults to yes now. 
        
        * Added AC_MSG_CHECKING/AC_MSG_RESULT to AC_EGREP_HEADER stuff.
        
        * Added --enable-deprecated-linux-pw-encrypt option to configure. 
        
        * Added compat code for Dynix. It have incompatible SIGINFO
        defination in sys/siginfo.h.

Thu Apr 17 02:06:16 1997  Tero Kivinen  <kivinen@ssh.fi>

        * scp now understands -o options, and passes them to ssh.
        
        * Some kerberos DCE fixes from Doug Engert <DEEngert@anl.gov>. 
        
        * Added read_confirmation function to readpass.c that will ask
        confirmation from user using either stdin or /dev/tty. This is
        used when using StrictHostKeyChecking is set to ask. 
        
        * Changed StrictHostKeyChecking to have three states: yes/no/ask.
        Idea from Markus Linnala <maage@ee.tut.fi>.

        * Fixed make-ssh-known-hosts.pl to use 3des instead of rc4.
        
        * Added -p option to ssh-add (read passphrase from pipe). Idea
        from Charles Karney <karney@pppl.gov>. 
                
        * Added signal(SIGCHLD, SIG_DFL) on child before using libwrap
        stuff in sshd.c.
        
        * Fixed mv sshd sshd.old to use correct directory (sbindir).
        (reported by several people).
        
        * Fixed putenvs in the xstrdup (reported by several people).

Sun Apr  6 00:41:55 1997  Tero Kivinen  <kivinen@ssh.fi>

        * gmp: Added -Wa,+DA1.1 to SFLAGS on hppa1.1 machines.
        Fixed the (cd mpn; ...) > foo stuff so that it works even if
        some brain damaged cd prints something (it does in hpsux). 
        
        * Removed restriction that ssh only used priviledged port if
        server port was < 1024.
        
        * Added setting of allow_severity and deny_severity in ssh.c too,
        because newchannels.c uses libwrap also. 
        
        * Fixed ssh-agent option parsing.

        * Added -- option support in ssh-agent, patch from
        Charles M. Hannum <mycroft@gnu.ai.mit.edu>.
        
        * Added closing of agent socket in parent process, patch from
        Charles M. Hannum <mycroft@gnu.ai.mit.edu>.
        
        * Added check for existance of O_NOCTTY (patch from
        KOJIMA Hajime <kjm@rins.ryukoku.ac.jp>).
        
        * Added setting of SSH_AGENT_PID when running command too. 

        * Fixed ssh-add SECURE_RPC support, so it will work even if no
        passphrase is found. 
        
        * Fixed closing of pty, and changed it to use shutdown first and
        close the pty only after pty have been released, patch from
        Charles M. Hannum <mycroft@gnu.ai.mit.edu>. 
        
        * Fixed typo on allow_tcp_forwarding code.
        
        * Fixed the quoting of ' character in readpass.

        * Changed order of environment variables set to child, because
        digital unixes telnet dumps core if USER is the first
        environment variable set.
        
        * Added code that will set all ip-address to xauth so it should

Fri Jul 12 09:16:36 1996  Tomi Salo  <ttsalo@piippu.ssh.fi>

        * configure.in, Makefile.in: Detached ssh-askpass from
        NORMAL_PROGRAMS to X_PROGRAMS, which is defined if X is
        found.

        * configure.in, login.c: Two small fixes for Cray (-lrsc,
        length of utmp id) and configuring in zlib-1.0.3.

        * newchannels.c: Fixed X11 connection socket paths for
        HP-UX.

Tue Jul  2 10:20:17 1996  Tomi Salo  <ttsalo@piippu.ssh.fi>

        * configure.in: Added -lipc for bdsi 2.1

Thu Jun 27 13:47:14 1996  Tomi Salo  <ttsalo@piippu.ssh.fi>

        * login.c (record_login): FreeBSD doesn't tolerate > 16
        char hostnames, use ipaddr instead

        * channels.c (channel_after_select): Merged fixes for
        tcp-wrappers from Rafal Maszkowski <rzm@torun.pdi.net>

Wed Jun 26 10:37:19 1996  Tomi Salo  <ttsalo@piippu.ssh.fi>

        * configure.in, pty.c (pty_allocate): Again a new way of
        allocating pseudo ttys, getpseudotty() in DYNIX/ptx 2.1. Also
        changes in configure.in for DYNIX.

        * sshd.c: use setpgrp() instead of setsid() on ultrix (as in
        versions < 1.5).

        * config.h, configure.in, includes.h, login.c, signals.c: Merged
        SCO fixes from Brian Murrell <Brian_Murrell@bctel.net>.

Tue Jun 25 16:31:40 1996  Tomi Salo  <ttsalo@piippu.ssh.fi>

        * pty.c (pty_allocate): Merged SCO fixes from Gert Doering
        <gert@greenie.muc.de>.

Fri Apr 26 03:12:19 1996  Tatu Ylonen  <ylo@pilari.ssh.fi>

        * sshd.c: Fixed ip address in "Closing connection" message when
          run from inetd.

        * sshd.c: Improved error messages related to not being able to 
          read host key when not root.

        * ssh-agent.c: Fixed bugs when receiving multiple simultaneous
          connections.

        * ssh-agent.c: Fixed major memory leaks.

        * signals.c: Check for SIGURG == ISGIO (Linux).

        * pty.c: Fixed process group setting on NeXT.

        * mpaux.c: Fixed some 32-bit dependencies to make the code run on
          16-bit machines.

        * No longer check for perl5.001 (just perl5 and perl now).

        * Also grep "installed" when checking for OSF/1 C2 security.

        * Fixed SOCKS support.  Fixed bugs in reconnecting with SOCKS.

        * Added support for HPUX 7.x.

        * Makefile.in: don't include make-ssh-known-hosts.1 in
          DISTFILES.

        * No longer remove some long ago obsoleted files in install.

Sun Feb 18 18:20:26 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * sshd.c: Use setluid to set login uid on OSF/1.

Thu Feb 15 11:17:26 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * sshconnect.c: When connecting with proxy, close userfile pipes
          after fork.

Wed Feb 14 00:28:50 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * configure.in: don't use setsid on mips-dec-mach3.

        * cipher.h: comments about len in encrypt and decrypt.

Sun Feb 11 16:35:37 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * Released 1.2.13.

        * sshd.8.in: Fixed a minor typo.

        * configure.in: Give error on linux if the system has the libg.sa bug.

        * servconf.c: Fixed pid file default setting.

Sat Feb 10 14:33:29 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * Changed licensing conditions in COPYING.

        * ssh.c: Recognize -8 as an option (but it is ignored, as ssh is
          always 8-bit clean).

        * sshd.8.in: Documented SIGHUP.

        * Merged PidFile patches from Danek Duvall
          <duvall@dhduvall.student.princeton.edu>.

        * sshd.c (and other files): added new packet type
          SSH_CMSG_MAX_PACKET_SIZE.  This can be used to limit packet size
          sent by the server, which is helpful when implementing the Windows
          client, as it is troublesome to manipulate buffers larger than 64k
          on Windows.

        * channels.c (channel_output_poll): Don't emit any more data to
          the output buffer from channels if it is already quite full.
          This may reduce problems with X or TCP/IP traffic jamming the
          interactive shell and/or prevent the size of sshd growing.

        * sshd.c (do_child): clear the random number generator before
          changing uid.

        * sshd.c (do_child): Run $HOME/.ssh/rc and /etc/sshrc with the
          user's shell.  These used to be run with /bin/sh even if the
          user's shell was /bin/sync.

Fri Feb  9 00:35:21 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * userfile.c (do_popen): Preserve XAUTHORITY.

        * sshconnect.c: When initializing the random number generator,
          read also some noise from the systemwide seed file.  This
          prevents the user from guessing his own session key (which,
          together with sophisticated IP spoofing attacks on the local
          network, might be exploited to masquerade as another user).

        * ssh.c: Moved the fork caused by the -f option until after all
          forwardings have been started.  This makes it more useful in
          scripts.

        * Eliminated rc4.  Added arcfour, which is a cipher based on a
          usenet posting in Spring-1995.  It is widely believed and has
          been tested to be equivalent with RC4 (RC4 is a trademark of RSA
          Data Security).

        * configure.in: Added check to determine if found rsh is actually
          ssh.  This helps to avoid errors where ssh enters a loop
          executing itself when trying to fall back to rsh.

        * New functions log_severity() and fatal_severity().  These
          are like log() and fatal(), but allow specifying the severity
          of the logged message.  The primary purpose of these functions
          is to avoid innocuous messages (e.g. connection closed) being
          logged with high severity.

        * servconf.c, readconf.c: accept "true" and "false" as values for
          yes/no options.

Thu Feb  8 13:51:59 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * sshd.c: moved userfile_uninit() to before forking the child.

        * Merged make-ssh-known-hosts changed from kivinen@niksula.hut.fi.

            * added builtin ping (much faster, because you can set the
              timeout to very short value (1-2 seconds, default is 3
              seconds), and because it 'pings' the ssh port it will find
              only those hosts with sshd running.

            * recursive scanning (scans all subdomains of domain
              automatically, use --norecursive to turn it off).

            * automatically use all nameserver entries for domain until
              it will get something if the origin or other nameservers
              refuse to answer queries.

            * trust the key returned from daemon by default (use
              --notrustdaemon to get old behavior).

            * --keyscan option that will make list of hosts for keyscan
              (not compatible with current version ssh-keyscan, because it
              will output all ipaddress separated with commas in the
              ipaddress field, and ssh-keyscan expects only one ipaddress,
              hopefully ssh-keyscan will accept this format too later, for
              now you can use sed 's/^\([0-9.]*\),[,0-9.]*/\1/g' to make it
              ssh-keyscan compatible).

            * added some diagnostic prints to generated ssh_known_hosts:
              # Domain = hut.fi, server = Santra.Hut.Fi
              # Found 4391 hosts, 361 CNAMEs (total 11570 lines)
              # SOA = santra.hut.fi jtv.hut.fi. (10001423 3600 300 3600000 
                3600)
        
Mon Feb  5 20:41:29 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * ssh-askpass.wish: Merged changes from Antti Huima
          <ahuima@niksula.hut.fi>.

        * Removed garbage line from RFC.

Mon Jan 29 23:45:58 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * canohost.c (get_remote_ipaddr): If using two different
          descriptors, check if they are internet-domain sockets with
          the same peername; if so, return that address.  This should make
          ssh be able to return the correct peername when started from
          inetd.

Fri Jan 26 23:10:20 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * pty.c: Merged Cray pty fixes from Wayne Schroeder
          <schroede@SDSC.EDU>.

Thu Jan 25 08:05:18 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>
        
        * sshd.c (do_child): moved clearing of resources before switching
          to user privileges.
        
        * sshd.c: Fixed a bug where fclose was used for a file opened with
          popen.

        * randoms.c (random_acquire_light_environmental_noise): Take 128
          bits of noise from /dev/random about every five minutes.  It
          used to be more often, but people were complaining that ssh
          completely exhausts /dev/random.

        * Eliminated uid swapping code.

Wed Jan 24 13:06:24 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * Makefile.in: $$ (referring to current pid) -> $$$$ because
          "make" eats the other $.

Mon Jan 22 01:21:41 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * serverloop.c: fixed problems with data not always being sent to
          the client.

Sun Jan 21 13:31:55 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * Makefile.in (install): Install scripts with INSTALL_DATA (patch
          from Andrey Chernov <ache@astral.msk.su>).

Wed Jan 17 11:45:05 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * configure.in: Added checking for libshadow.a if have /etc/shadow.

Mon Jan 15 10:13:52 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * buffer.c (buffer_append_space): Decreased buffer size increase
          from 32768 bytes to 4096 bytes.  This should reduce the ssh
          process size in interactive use.

Sun Jan 14 10:29:19 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * canohost.c (get_remote_hostname): Socket options (such as source
          routing) were checked for descriptor 0, which is wrong.  Fixed.

Thu Jan 11 18:48:09 1996  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * sshd.c: Add BINDIR to DEFAULT_PATH.  The primary purpose of this
          is to make it more likely that scp will be found on the remote
          machine in case the shell does not read the user's rc-files.
          Corresponding changes in Makefile.in.

        * configure.in: Added code to recognize $HOME/.MailBox as a possible
          incoming mailbox name (to be set in MAIL environment variable).
          sshd.c: code to handle MAIL_SPOOL_FILE
          acconfig.h: HAVE_TILDE_NEWMAIL -> MAIL_SPOOL_FILE

        * configure.in: Add -linet on Dynix/ptx (from geek+@cmu.edu).

        * login.c: Added SysVr4 (Solaris) utmp patches from Ian Donaldson
          <iand@aone.com.au>.
          configure.in: Added check for makeutx.

        * Makefile.in: Added target hostinstall.  This can be used in a
          networked environment to generate host key and install config
          files on other machines after installing the binaries to a shared
          directory on one machine.

        * sshd.c (login_permitted): Added code to check for expired
          accounts on AIX.  Also checks whether remote logins to the
          account are permitted.

        * configure.in: Added check for -lauth (function
          authenticate_user) in Ultrix-specific code.

        * random.c (initstate): Changed to use unsigned int instead of
          u_int (u_int is not defined on all systems).

        * pty.c (pty_allocate): Use revoke() if it exists.  Added check
          for it in configure (patches from Christos Zoulas
          <christos@deshaw.com>).

        * When falling back to rlogin, run rlogin if called as rlogin or
          rsh.  Otherwise, rsh may exec wrong rlogin, resulting in a loop.

        * sshd.c (main): Print host type with -d.
          ssh.c: Print host type with -v.

        * ssh.c (rsh_connect): Made rlogin run rlogin, rsh run rsh, etc.

        * configure.in: Changed to use autoconf-2.7.
          Makefile.in: made bindir, sbindir, mandir separately configurable.
          config.guess: updated to config.guess from autoconf-2.7.
        
        * channels.c (x11_input_open): Use /tmp/.X11-unix/`hostname`0
          instead of /tmp/.X11-unix/X0 on HPSUX.

        * configure.in: No vhangup on MachTen.
          includes.h: need machine/endian.h on MachTen.

Sat Dec 16 14:03:21 1995  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * Removed LIBS from gen_minfd link line.

Tue Dec  5 12:22:20 1995  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * Minor fixes to ssh.1.in.

        * auth-passwd.c: fixed C2 security password authentication on alpha.

        * sshd.c: increased SO_LINGER times to 15 seconds.

Fri Dec  1 14:12:31 1995  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * sshd.c, pty.c: Call setsid() also for non-pty logins.  This is
          needed on BSD 4.4, where setlogin() works on a process group
          basis (What a Stupid Idea!), and setlogin() is being changed in
          FreeBSD to only work for process group leaders (Continued Brain
          Damage!).

        * auth-passwd.c: Added support for Ultrix enhanced security.

        * Renamed field "howmany" in authfd.h due to conflicts with system
          headers on Solaris 2.4.

        * scp.c (sink): Don't use O_TRUNC if ftruncate exists.  Avoids
          corrupting files when copying on top of itself.

Wed Nov 29 15:57:03 1995  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * Improved debugging messages sent to client when Rhosts/RhostsRSA
          authentication fails.

        * configure.in, uidswap.c: Fixed uid-swapping on ultrix and aix.

        * tildexpand.c: for ~/file, if HOME is set, use it; use getpwnam
          in this case only if HOME is not set.

Tue Nov 21 03:01:23 1995  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * serverloop.c: Trying to prevent spurious "Waiting for
          connections to terminate" messages at client exit.

        * ssh.1.in: Fixed small typo (.ne3).

        * sshd.c: Fixed other setsid on Ultrix.

Fri Nov 17 16:19:20 1995  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * Released 1.2.12.

        * channels.c: Commented out debugging messages about output draining.

        * Added file OVERVIEW to give some idea about the structure of the
          ssh software.

Thu Nov 16 16:40:17 1995  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * canohost.c (get_remote_hostname): Don't ever return NULL (causes
          segmentation violation).

        * sshconnect.c: Host ip address printed incorrectly with -v.
        
        * Implemented SSH_TTY environment variable.

Wed Nov 15 01:47:40 1995  Tatu Ylonen  <ylo@trance.olari.clinet.fi>

        * Implemented server and client option KeepAlive to specify
          whether to set SO_KEEPALIVE.  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.
