CHANGES
=======
version 7.2.5 (Jan 27, 2003):
- fixed many documentation bugs - reported by Dave Stuit
<djs@tellme.com>
- added -I option to client which operates like -i, but on the
primary conserver only - suggested by Dave Stuit
<djs@tellme.com>
- added SIGUSR2, which does not reread the configuration file,
but does everything else SIGHUP does - suggested at LISA 2002
- fixed bug where LOGDIR setting gets used even if no logfile
is wanted
- added -R option to server to prevent client redirection to
other conserver hosts - suggested by Todd Stansell
<todd@stansell.org>
version 7.2.4 (Oct 14, 2002):
- added --with-openssl for some client/server encryption
- added -E option to client and server to allow for non-encrypted
connections (encryption is the default if compiled in)
- added -c option so credentials (certificate and key) can be
exchanged between client and server
- expanded -V output to show what optional bits actually got
compiled into the code (libwrap, regex, etc)
- compilation errors on non-shadow file systems without using
--with-pam - reported by Jesper Frank Nemholt <jfn@dassic.com>
- client now prefers $LOGNAME, then $USER, then the current uid
for its -l default - suggested by Dave Stuit <djs@tellme.com>
- putting back socklen_t usage - it's the right thing to do,
so tell me where it breaks things
- configure options --with-cffile and --with-pwdfile now
recognize fully-qualified pathnames - suggested by Kjell
Andresen <kjell.andresen@usit.uio.no>
version 7.2.3 (Sep 23, 2002):
- checking for duplicate console names got lost in the major
7.2.0 rewrite of that code. it's back now, with a couple of
other edge-case fixes i noticed while scanning the code -
reported by Dave Stuit <djs@tellme.com>
- added --with-pam and PAM authentication support - suggested
by Stu May <jsmay@wasteofbits.com>
- added -F server option to prevent automatic reinitialization
of failed consoles ('|' syntax consoles which exit with a
zero status are still reinitialized) - requested by William P
LePera <lepera@us.ibm.com> and Malcolm Gibbs
<Malcolm.Gibbs005@msd.govt.nz>
- successful automatic reinitialization of consoles now attaches
a client that wants read-write mode
- added read-only client wish to become read-write in -i output
- moved to autoconf-2.54 and fixed some small configure.in bugs
Many thanks to John R. Jackson <jrj@purdue.edu> for the following
fixes, cleanups, and enhancements...
- "lost timestamps" bug (SIGALRM/sleep()/usleep()/tcp_wrapper
interaction)
- compiler warnings, bad fileOpenFD tests, and ability to use
a colon after an equal in the config file (LOGDIR=C:\Logs)

Stuit <djs@gnac.com>
- AIX 5.1 pseudo-terminal support broken - patch by William P
LePera <lepera@us.ibm.com>

- check for valid baud rates (invalid resulted in '0') -
reported by Andrew Gallatin <gallatin@cs.duke.edu>
- a broadcast messages to others on your console can now be

The following suggested by Trevor Fiatal <trevor@seven.com>
- Widened username field of 'console -w' output
- Added server hostname to password entry prompt
- AC_CHECK_LIB replaced with AC_SEARCH_LIBS in configure.in so
that irrelevant (and sometimes incompatible) libraries aren't
linked in
version 7.1.1 (Aug 4, 2001):
- Now using getlogin() for real username info - suggested by
Dave Stuit <djs@gnac.com>
- gethostbyname() failure for a console now doesn't cause a
shutdown - reported by Todd Stansell <todd@stansell.org>
- Shutdown via client -q/-Q fixed (broken in 7.1.0 because of
master process fork() code)
- Password file parsing fixed to allow for empty passwords -
allowing users to access conserver without a password prompt
- Both the password and configuration files no longer have
line length limitations, they now support comments (`#' lines),
and lines with leading whitespace are continuations of
previous lines
- Client hostname/ip sometimes not printed - reported by Todd
Stansell <todd@stansell.org>
version 7.1.0 (Jul 26, 2001):
- Hostname in access list that began with a digit was treated as
an IP address - only strings using [0-9./] are considered CIDR
notation and they must be of the form a.b.c.d[/n]
- Fixed SIGHUP always opening logfile(-L) - shouldn't without -d
- Fixed 'make install' problem under MacOS X and cygwin
- Client -l option totally broken in 7.0.3 - patch by Daniel E.
Singer <des@cs.duke.edu>
- Client now accepts IP addresses from server and server now sends
the IP of the socket instead of its hostname to the client,
fixing part of the multi-interface problem
- Client no longer passes hostname to server along with username
- Client now turns off IEXTEN so stuff like ^V passes through
- Server now pauses one second when reopening a TCP-based console
to give the terminal server a chance to clean up
- Master server process now fork()s when accepting clients
- timestamp-spec can be numeric only ('m' default)
- Ambiguous console name error now shows ambiguous list
- Console list in conserver.passwd can now have whitespace
- Access lists in conserver.cf can now use ',' as a separator
- Added special '*any*' username in conserver.passwd
- Username match (real or '*any*') now stops conserver.passwd file
processing - allowing you to lock out users
- Added -u flag to server to enable "unloved" output - this is the
opposite of the old -n flag, which now does nothing
- Added -7 flag to client and server for stripping the high bit
of data on either side (--disable-8bit removed)
- Added -b to server to specify the base port number for the
secondary communication channel - based on code from Enrik
Berkhan <Enrik.Berkhan@planb.de>
- Changed -d and -D flags to -r and -R in client - now -D enables
debugging mode in the client (and -d is unused)
- Changed -r to -G in client so -r could be used for the above
- Client now uses getpassphrase() (if available) for > 8 char
passwords - pointed out by Gregory Bond <gnb@itga.com.au>
- Improved signal handling
- Improved process handling (POSIX waitpid() now necessary)
- Significant rework of STREAMS-based pseudo-tty code
- TCP connections ('!' config syntax) now have some Telnet protocol
knowledge, removing the "noise" seen when connecting to a terminal
server - reported by Todd Stansell <todd@stansell.org>
- Various code and message "pretty-printing" done
- Client and server both run in Windows (tested with Windows
2000) under the cygwin environment thanks to a debug-fest with
Emmett Hogan <hogan@gnac.com>
- Using autoconf version 2.50
- Man pages reworked and conserver.passwd page created by Dave
Stuit <djs@gnac.com> - the pain he suffered documenting
the program (and pointing out many of the bugs fixed above)
should help endless others
version 7.0.3 (Jul 5, 2001):
- "Off by 1" bug in 7.0.2 line-oriented timestamp code fixed (extra
chars in logfile) reported by Matthew Cheek <cheek@mars-systems.com>
- TODO file added to distribution
- 'attached', 'detached', and 'bumped' actions now written to
console logs that have 'a' in timestamp-spec field
- Default timestamp specification with TIMESTAMP= in .cf file
- Config file much more forgiving about whitespace in fields
- gethostbyaddr() failures are no longer fatal
- Added -M to server to specify the address to listen on
based on code from Enrik Berkhan <Enrik.Berkhan@planb.de>
- Added -p option to client and server to specify the port to
connect to and listen on (--with-port still sets the default)
- Added logfile output when going into daemon mode
- Added --with-logfile to configure
- Added -L to override compile-time logfile location
- SIGHUP reopens this logfile as well as previous behavior
- Run as root only restriction removed - warning now (if necessary)

- Using inet_ntoa() now instead of peeking at bytes
- Fixed up -V (and -Vv) output for client and server
- Increased conserver.passwd read buffer (CheckPasswd())

- Fixed pseudo-terminal ('|' syntax in .cf file) bug with Solaris
and other STREAMS-based systems (actually works now in 7.X)
- Line-oriented timestamps in logfiles (see 'l' mark
specification) based on patch from Benn Oshrin
<benno@columbia.edu>
- Generalized debugging output, info messages and error messages
- Moved library search up in configure.in so function calls are
detected properly
- Permissions of install-sh were wrong
- Trimmed the README file and now distribute conserver.html
- Redhat RPM bundle (contrib/redhat-rpm) contributed by Paul
Heinlein <heinlein@measurecast.com>
- Cleaned up gcc warnings (for Solaris 7, at least)

<fenner@research.att.com>
- PID file patch by Martin Andrews <mandrews@netgenics.com>
version 7.0.0 (Feb 18, 2001):

version 6.15 (Mar 6, 2000):
- Added debug flag (-D) and the beginning of debug output
- A timeout can now be set for TCP connect() calls. The
default is 30 seconds. Hosts not responding are only
