+version 8.0.8 (Dec 2, 2003):
+	- added client ^Ec| sequence for running a command on the client

+	- now unallocate client lists when forking new child conserver
+	  processes
+	- changed strdup() to local StrDup() so dmalloc can gracefully
+	  track changes

+version 8.0.1 (Sep 29, 2003):
+	- fixed bug in access list parsing where multiple addresses per

+	  <trevor@seven.com>
+	- added client -d option for disconnecting users specified by
+	  username and/or console - suggested by Trevor Fiatal
+	  <trevor@seven.com>

+	  reported to work just fine
+	- break strings with '\d' are interpreted as a delay, which can
+	  be specified in the config file (default 250ms)
+	- removed 'reset -x' portion of default break sequence #3
+	- remote conserver hostnames now properly match - had to be a
+	  character string match previously
+	- hostname aliases now checked against access lists and the
+	  matched name is used for logging
+	- added --with-trustrevdns to enable the use of reverse DNS
+	  information for access list checks [not recommended] - see the

+	  socket connection now has a proper timeout (and can happen
+	  simultaniously)
+	- partial write()s are properly buffered and retried
+	- made all sockets (including SSL) non-buffered
+	- client now supports piping data to it and properly printing

+version 8.0.0-beta1 (Jul 4, 2003):
+	- ***NOTICE*** the format of conserver.cf and conserver.passwd
+	  has completely changed.  see the INSTALL file for
+	  upgrade instructions (it should be "fairly painless").
+	  some documentation has been updated to reflect the new world,
+	  some hasn't - my goal for beta2 is to have all the docs updated
+	- many command-line options now also conserver.cf options options
+	- POSIX termios interface now required for compilation - some

+	  <andreas@planix.com>
+	- added password support for HP-UX trusted systems - immense
+	  help by Greg Brown <gregb_ka6max@hotmail.com>
+	- potential SIGUSR1 bug where cached terminal server availability
+	  wasn't being cleared correctly - reported by Dave Stuit
+	  <djs@tellme.com>
+	- server is now more forgiving about errors instead of just
+	  giving up and shutting everything down
+	- consoles that have trouble coming up (and are forced down)

+	  in configuration file - patch by Igor Sviridov <sia@nest.org>
+	- memory leak using openssl library plugged
+	- automatic reinitialization of failed consoles now retries
+	  every minute like the manpage says it does - reported by Chris
+	  Fowler <cfowler@outpostsentinel.com>
+	- when -R option is used, substring matches on console names
+	  from clients only match local console names (and if that
+	  fails just remote console names) but ambiguous name list

+
+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

+	- 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>

+	  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

+	- 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

- 1) Where can I find the software?
+ 1) What is conserver?
+
+    From an email I quickly wrote to a potential user (I'll try and
+    clean it up and make it a little clearer sometime soon):
+
+    Conserver is an application that allows multiple users to watch a
+    serial console at the same time.  It can log the data, allows users
+    to take write-access of a console (one at a time), and has a
+    variety of bells and whistles to accentuate that basic
+    functionality.  The idea is that conserver will log all your serial
+    traffic so you can go back and review why something crashed, look
+    at changes (if done on the console), or tie the console logs into a
+    monitoring system (just watch the logfiles it creates).  With
+    multi-user capabilities you can work on equipment with others,
+    mentor, train, etc.  It also does all that client-server stuff so
+    that, assuming you have a network connection, you can interact with
+    any of the equipment from home or wherever.

+ 7) How do I set up a local serial port for no parity?
 
-    The conserver.cf man page will have this in the 6.17 release,
-    but the answer is to use a 'p' after the baud rate.  So, '9600p'
-    is 9600 baud, no parity.
+    The manpage has the answer to this question.  For those that don't
+    want to read it, here are some guidelines.  For pre-7.2.2, you'd
+    want to use a 'p' after the baud rate ("9600p", for example).  For
+    7.2.2 thru 7.2.7, you can use an 'n'.  For 8.0.0 and beyond, you use
+    'parity none;'.
+
+ 8) Is "Conserver" a trademark or registered trademark?
+
+    The best answer I can give is "not as far as I know".  A couple of
+    quick searches through the source code doesn't find any claim of a
+    trademark.  I've never done a registered trademark search, but if
+    it had been registered (by a previous author), I'm sure it would be
+    mentioned.  But I'm no lawyer and don't deal with these types of
+    things, so I'm not exactly sure what I'm taking about and my answer
+    becomes a very vague "not as far as I know".
+
+ 9) When I connect to a console, it says it is down.  Why?
+
+    There are multiple reasons why this might happen.  First, see if it's
+    just a remnant of some other temporary problem.  Try and bring the
+    console up by doing a '^Eco' from the client.  If that doesn't work,
+    there's a more serious problem which, hopefully, the conserver logfile
+    will explain.  Check the log for any permission problems, connection
+    refused messages, etc.  You might get more useful information in
+    the log by using the -v option or even by enabling debugging with
+    -D (ideally that shouldn't be necessary).  Depending on the type of
+    console, your system might be out of pseudo-terminals, another process
+    might have a terminal server port occupied (another console server or
+    telnet session), or there was an unseen typo in a path or hostname.
+    The logfile should show hints of things like this and other issues.
+
+10) Is there a technical reason why --with-maxmemb's default is 16?
+    I've changed mine to 96.
+
+    The following is an array of things you need to think about when
+    adjusting --with-maxmemb.  It's a bit long, but it's an important
+    question.
+
+    The big reason (and the main reason for conserver spawning multiple
+    processes) is the maximum number of open files a process can have.
+    Each console can have a few file descriptors associated with it
+    (device, logfile, connected users, and listening socket).  So, each
+    process will have about ( 2 * consoles + users + 1 ) open files
+    (--with-maxmemb sets the maximum number of consoles per process
+    in the equation).  Although most current operating systems allow a
+    large number of open files per process, the general assumption is
+    it's still pretty low.
+
+    You also have the speed of your conserver host vs the rates at which
+    data could be streaming to it.  Go back a decade and this was probably
+    more of an issue than today, but it's still something to think about.
+
+    And then you have the problem of delays.  If any of the 96 console
+    connections "lock up", it'll delay all activity on the 96 consoles.
+    With 16, there's less of an impact.  This can be an issue once the
+    server is up or during startup.  Also, with 16 consoles per process,
+    you get a bit more parallelization during startup.
+
+    So, is there any reason not to up the number to 96?  No.  Assuming you
+    know the risks and weigh things appropriately.  If I remember right,
+    I've upped the number to 48 at some sites.  But that was mainly to
+    reduce the memory footprint in older versions of the code which had
+    statically allocated buffers.  No need to worry about that with the
+    current code.  Personally, I wouldn't change from 16 unless there
+    was a really good reason (like wanting to only have one child process
+    for firewall rules or some such reason).
+
+99) OK, things just don't seem to work.  Help?!?
+
+    Yes, this is a pretty vague question, but here are a few tips that
+    might help.
+
+    - Is your low-level serial connection correct?  Incorrect cables,
+      adapters, wiring, etc. could be the issue.  Using a signal tracer
+      or attaching other equipment that's known to work (like a laptop)
+      might be enlightening.  Check out
+      http://www.conserver.com/consoles/msock.html for basic serial
+      information (or http://www.conserver.com/consoles/ for even more
+      info).
+
+    - Can you talk to the serial port with different software?  Try
+      using tip or minicom or another application to make sure you can
+      interact with the port.  If you're not seeing the right info
+      here, there may be a baud rate issue, a lack of a getty (or
+      equivalent) running on the host or...*shrug*.  But, if you've
+      determined that you already have a valid low-level signal
+      connection, you shouldn't have to worry about that level of
+      problem.
+
+    - So, you're getting the proper interaction from other
+      applications, but not conserver?  Are the port name and baud rate
+      correct in the conserver.cf file?  When you start conserver
+      (adding -v doesn't hurt), are there any warnings/errors?  Is the
+      port in the "up" state when you use "console -u"?  If not, what
+      happens when you connect and then do a "^eco" escape sequence to
+      bring it up?  What does the conserver process say when you do
+      this?  These are the types of things I look at first.  If that
+      doesn't help you determine the problem, others will want to see
+      this info (and possibly the same steps with both the client and
+      server using the -D option) to be able to help.  Posting your
+      questions to the users mailing list is probably your next step.
+
+    - Have you tried a search on the conserver site (it searches
+      mailing list traffic as well) to see if someone else has gone
+      through the same problem?

+Upgrading?
+
+    Whenever you upgrade I suggest you upgrade both the client and
+    server.  Most times, however, you can get away without upgrading
+    the client (it's usually a fairly static piece of code).  I'll
+    document any dependencies here, but check the CHANGES file for any
+    new features added to the client if you're considering *not*
+    upgrading.
+
+    Version 8.0.2
+
+	- I've added a '^Ec;' sequence to allow the client to signal the
+	  server as to when it's ready to see console data.  Without
+	  this, verbose consoles will prevent clients from attaching
+	  (the client sees unexpected data).  An 8.0.2 client should be
+	  compatible with an 8.0.1 server, but an 8.0.1 client is not
+	  compatible with an 8.0.2 server.
+
+    Version 8.0.1
+
+	- There's a slight client/server protocol change to implement
+	  the new 'initcmd' console option.  If you use this
+	  functionality with an 8.0.0 client, you'll run into a
+	  compatibility problem while the 'initcmd' command is running.
+
+    Version 8.0.0
+
+	- The client/server protocol has been rearchitected.  You *MUST*
+	  use an 8.0.0 client with an 8.0.0 server.  No combination of
+	  client/server will work with pre-8.0.0 code.
+
+	- Upgrading from pre-8.0.0 code to 8.0.0 and beyond requires
+	  you to change your conserver.cf and conserver.passwd files
+	  because both of the file formats have changed.
+
+	  The conserver.cf file changes are so major that there is a
+	  convert program available in the conserver subdirectory.  Just
+	  run './conserver/convert <old-cf-file>' and it will attempt a
+	  conversion to the new format, sending it to stdout.  Any errors
+	  will be printed to stderr.  There are a couple of things
+	  you might need to adjust.  First are the user access lists.
+	  If you are restricting users to certain consoles in your old
+	  conserver.passwd file, you'll need to move those restrictions
+	  into the new conserver.cf file.  Restrictions are set with the
+	  'ro' and 'rw' tags in the configuration file.  Second are the
+	  'access' blocks.  What get produced by the convert program
+	  will be functionally equivalent to the old behavior, but you
+	  may be able to tune things to better suit your environment.
+
+	  The conserver.passwd file's console restrictions have moved,
+	  as described above.  So to convert the conserver.passwd file,
+	  all you really need to do is something like:
+
+		awk -F: '{print $1 ":" $2}' <old-passwd-file>
+
+	  If you have comments or continuation lines in your file,
+	  you'll have to do a bit more cleanup to strip out the third
+	  field (which is what the awk command is intending to do).
+
+	- Conserver no longer trusts reverse DNS information by default.
+	  If you use the --with-trustrevdns configure flag, you can
+	  re-enable the use of gethostbyaddr() [I don't recommended it,
+	  however].  If you are using domain names in access lists,
+	  you'll either need to change those to use hostnames and/or ip
+	  addresses/ranges or use the --with-trustrevdns flag.  For
+	  example, if you have (in the
+	  8.0.0 format):
+
+		allowed conserver.com;  # allow *.conserver.com
+
+	  then you'll need to worry about this change.  If you only use
+	  full hostnames, you shouldn't have to do anything.
+
+    Version 7.2.4
+
+        - If SSL support is compiled into the code, older versions of
+          the client and server are, by default, incompatible because
+          encrypted connections are a requirement.  Use of the -E flag in
+          the client and/or server can work around this (but I discourage
+          this - please upgrade the clients and servers instead).
+
+    Version 7.2.0
+
+        - The code related to broadcast messages in the client (-b) has
+          changed.  If you want the username to come across properly in
+          the broadcast message, you'll need to make sure you upgrade
+          to the 7.2.0 client.
+
+    Version 7.1.1
+
+        - Both conserver.passwd and conserver.cf file parsing behaves
+          the same now.  Both use leading whitespace as a continuation
+          line indicator - if you have leading whitespace on a line
+          (aside from comments) you probably should remove it.
+
+    Version 7.1.0
+
+        - The client/server protocol has changed.  You *MUST* use a
+          7.1.0 client with a 7.1.0 and above server.  A 7.1.0 client
+          is *not* backward compatible with a pre-7.1.0 server.
+
+        - Some of the flags in the client (-d, -D, and -r) and server
+          (-n) have been given new identities to make the client and
+          server flags more uniform.
+
+        - The conserver.passwd file now uses the first username match
+          to determine access rights - if you have multiple instances
+          of a username in an existing password file, they must be
+          combined into one to continue to work.

+
+Other Information And Gotchas
+
+    - Debian Linux Distribution
+
+        The Debian folks have conserver distributed with the package
+        names of conserver-client and conserver-server.  They are in
+        the distribution "sid" and the "non-free" part (because the
+        Ohio State license doesn't explicitly allow for modification to
+        the code, even though it's totally implied and the intention of
+        the author - I've even got proof in email!  Oh well, can't
+        blame the Debian folks for being cautious - they've been burned
+        before, apparently).
+
+    - Potential GCC bug
+
+        Adam Morris <AMorris@providence.org> reported a problem with
+        the following line in console/console.c:
+
+            if ((in_addr_t) (-1) == pPort->sin_addr.s_addr) {
+
+        This tickles a GCC bug under HP-UX 11.11 using GCC 3.0.2 in
+        64-bit mode with optimization enabled (-O).  The bug could
+        possibly be provoked in other combinations as well.  His fix is
+        to change the line to:
+
+            if ((in_addr_t) (-1) == inet_addr(pcToHost)) {
+
+        It's also reported that newer versions of the compiler fix the
+        issue, so if you happen to have problems with the client
+        connecting to servers, you might be tickling this bug and you
+        can upgrade the compiler, turn off the optimization, or apply
+        this code change.

 Maintainer/Enhancer
 
-    Bryan Stansell (bryan@conserver.com) of Certainty Solutions, Inc. -
-    formerly Global Networking and Computing (GNAC).
+    Bryan Stansell (bryan@conserver.com)
 
 
-Big new version released!
+Documentation
 
-    7.0.0 is out! What's so great about 7.0.0? GNU's autoconf has been
-    integrated by Mark Roth (roth@feep.net)! I met Mark at the [1]LISA
-    conference last December and he (quite quickly) provided the patches.
-    I've been dragging my heels getting it out to others, but it's now
-    available.
-
-    Now that I have autoconf capabilities, I've taken out the need to edit
-    the conserver/cons.h file - everything is now a --with or --enable
-    configure argument (makes sense, doesn't it!?!). As with any X.0.0
-    release, I may have introduced something bad into the code for systems
-    I don't have access to, so be careful.
-
-    I've successfully built 7.0.0 on Solaris and Linux. I've been told the
-    client has built successfully under cygwin on NT (progress on the NT
-    front!). Last report shows FreeBSD as a failure (any coders out there
-    with FreeBSD have time to send me patches?). If anyone successfully
-    builds and installs the software under other operating systems, I'd
-    love to hear about it.
-
-
-Finally, a FAQ!
-
-    Here's the start of a conserver [2]FAQ. Got any additions? Let me
-    know.
-
-
-Mailing Lists
-
-    There are currently two mailing lists available.
-    [3]announce@conserver.com is an announcement-only mailing list for
-    informing of new versions, major developments, etc.
-    [4]users@conserver.com is for general Q&A, discussions, ideas, etc
-    for conserver users. You can sign up my sending a message to
-    list-request@conserver.com with a subject of "subscribe" or head
-    over to the online [5]web pages.
-
-
-Origin
-
-    The console server software found here is a heavily modified
-    version originally written by Tom Fine (fine@head-cfa.harvard.edu)
-    and then Kevin S Braunsdorf (ksb+conserver@sa.fedex.com). Patches
-    from Robert Olson (olson@mcs.anl.gov) were then applied to get
-    network console support.
-
-    Arnold de Leon (arnold@corp.webtv.net) then fixed various bugs and
-    added enhancements while at Synopsys. I then took the result and
-    continued fixing things and adding features we found useful.
-    Certainty Solutions has been supporting my coding efforts (in too
-    many ways to list) since 1996.
-
-
-The conserver.com Distribution
-
-    The result is a combination of many people's work. This version is
-    being released in hopes that it will help others. There is no
-    warranty or support implied by the distribution of the software.
-
-    As of version 6.1.7, the packaging and numbering scheme has
-    changed.  I used to package conserver as conserver-GNAC-v.vv. Since
-    GNAC (now [6]Certainty Solutions) has changed it's name I've
-    decided to drop the GNAC portion and use a 3 digit version number
-    (conserver-v.v.v). Why change the version numbering? I need to
-    differentiate this thread of the code from the original authors and
-    I couldn't come up with a good replacement for the GNAC name - sad,
-    but true.
+    See the INSTALL file for installation, the conserver.html file for
+    an overview, and the man pages for specifics.

-    Zonker Harris has fabulous documents regarding the hookup of
-    consoles to terminal servers and other such devices. His
-    [13]Greater Scroll of Console Knowledge is a great place to start.
+    Here's a list of systems that I've been told can successfully
+    compile conserver.  If anyone has more to add to this list (or

+---------------------------------------------------------------------------
+
+- Telnet protocol should be improved
+    - Not even RFC 854 compliant
+    - Option negotiation ignored - should we negotiate anything?
+    - Others?
+
+- better shadow file support
+    - what does this mean?  i've forgotten.
+
+- syslog?
+    Daniel E. Singer <des@cs.duke.edu> would like to see it - especially
+    in regards to --use-libwrap code
+
+- alternate (md5) password encryption support in conserver.passwd
+    - actually happens if the crypt() call supports it, like under linux
+    - hpux has bigcrypt() also, which we support, so maybe we're covered
+
+- config file examples for various configurations
+
+- per-line timestamps
+    - only when not connected?
+
+- pipe input/output (console <-> program) via 'console'
+    - some apps (net-ups thing, gdb) might need to talk to user
+    - ^Ec| does this, but the interact with user bits might not work
+
+- autologout?  setting per console?  gack, would have to interpret data.
+
+- "listen" capability (watch all/multiple consoles)
+
+- send data to multiple consoles (carbon copy) -
+    Steve Lammert <slammert@panasas.com>
+
+- authentication to terminal servers (ssh, passphrase, whatever)
+    - ssh should probably just be handled by invoking the ssh command.
+      so, that's really already covered, no?
+    - passphrase...hmmm..could really use some sort of send/expect
+      thing here.  you could write a wrapper script of sorts, but it
+      really would be nice to have a raw socket and do the right thing.
+
+- cyclades ts1000/2000 port : "Moses, Joel" <jmoses@deloitte.com>
+
+- config file for client (list of masters, for example)
+
+- strftime() idea for logfile names : Lars Kellogg-Stedman <lars@larsshack.org>
+
+- 9600baud log replay?
+
+- server -M flag should accept multiple addresses (comma separated)
+    - should client as well?
+
+- automatic log rotation in general : Egan Ford <egan@us.ibm.com>
+
+- website docs on serial port configs
+    - PCs (solaris x86, linux, *bsd, etc)
+    - lilo
+    - bios support
+
+- suggestions by Trevor Fiatal <trevor@seven.com>
+    - include server hostname on 'console -x' output
+
+- ability to configure strings to be sent to a console periodically :
+  Greg A. Woods <woods@planix.com>
+
+- show attach/detach events to/of spy console clients : Greg A. Woods
+  <woods@planix.com>
+
+- redefine client escape sequence in conserver.cf : Toby Gerhart
+  <toby.gerhart@eds.com>
+
+- send a string when connected to a console, so you can set the
+  xterm title, for example : Richard Threadgill <richardt@tellme.com>
+
+- allow for very long replays (hundres of lines) : John Stoffel
+  <stoffel@lucent.com>

+.SH NAME
+conserver.passwd \- user access information for
+.BR conserver (8)
+.SH SYNOPSIS
+.IB username : password
+.SH DESCRIPTION
+The
+.B conserver.passwd
+file is the user authentication and authorization file for
+.BR conserver (8).
+Upon each incoming client connection,
+.B conserver
+opens and reads the
+.B conserver.passwd
+file, so edits to the file take effect immediately.
+It reads only until the first
+.I username
+match.
+.PP
+Blank lines and comment lines (those beginning with a ``#'' and
+optional leading whitespace) are ignored.
+Non-ignored lines beginning with whitespace are considered
+continuations of the previous line.
+This allows you to span one logical line over
+many physical lines and insert comments wherever appropriate.
+.PP
+Each logical line consists of two colon-separated fields.
+Leading and trailing white space in each field is ignored.
+.TP
+.I username
+the login name of the authorized user,
+or the string
+.RB `` *any* ''
+to match any user.
+This is compared against the name sent by the
+.B console
+client, based either on the user's identity or on the
+.B \-l option.
+Since
+.B conserver
+only uses the first
+.I username
+match, a
+.RB `` *any* ''
+entry will apply to any user
+without an entry earlier in the file.
+.TP
+.I password
+the encrypted password,
+or the string
+.RB `` *passwd* ''
+to indicate that
+.B conserver
+should look up the user's password
+in the system
+.BR passwd " (or " shadow ") database."
+If PAM support has been enabled
+.RB ( --with-pam ),
+PAM lookups will be done instead of
+.BR passwd " (or " shadow ") lookups."
+If this field is empty, password checking is bypassed for this user.
+.SH EXAMPLE
+.TP 24
+.B mary:r71mXjfALB5Ak
+Mary uses the password specified above;
+it does not matter whether she has a login on the conserver host.
+.TP
+.B fred:*passwd*
+Fred may connect only with his regular login password on the conserver host.
+.TP
+.B bozo:*
+Bozo is only allowed to access a console if his password isn't used (since
+it's invalid) which means he needs to come from a
+.B trusted
+host.
+.TP
+.B *any*:*passwd*
+Anyone not listed above uses their regular login and password.
+.SH "SEE ALSO"
+.BR console (1),
+.BR conserver.cf (5),
+.BR conserver (8)
+.SH BUGS
+.PP
+There is currently no way provided by the conserver package
+to generate the encrypted password strings
+besides copying them from the system
+.B passwd
+database or running
+.BR crypt (3)
+via C or perl or some other language that supports it.

+
+          <P>Conserver is an application that allows multiple users
+          to watch a serial console at the same time. It can log
+          the data, allows users to take write-access of a console
+          (one at a time), and has a variety of bells and whistles
+          to accentuate that basic functionality. The idea is that
+          conserver will log all your serial traffic so you can go
+          back and review why something crashed, look at changes
+          (if done on the console), or tie the console logs into a
+          monitoring system (just watch the logfiles it creates).
+          With multi-user capabilities you can work on equipment
+          with others, mentor, train, etc. It also does all that
+          client-server stuff so that, assuming you have a network
+          connection, you can interact with any of the equipment
+          from home or wherever.</P>

+          additions? Let me know.

+
+          <H3>Origin</H3>
+
+          <P>The console server software found here is a heavily
+          modified version originally written by <A href=
+          "http://hea-www.harvard.edu/~fine/">Tom Fine</A> (<A
+          href=
+          "mailto:fine@head-cfa.harvard.edu">fine@head-cfa.harvard.edu</A>)
+          at <A href="http://www.ohio-state.edu/">Ohio State</A>
+          and then Kevin S Braunsdorf (<A href=
+          "mailto:ksb+conserver@sa.fedex.com">ksb+conserver@sa.fedex.com</A>)
+          at <A href="http://www.purdue.edu/">Purdue
+          University</A>. Patches from Robert Olson (<A href=
+          "mailto:olson@mcs.anl.gov">olson@mcs.anl.gov</A>) at <A
+          href="http://www.anl.gov/">Argonne National
+          Laboratory</A> were then applied to get network console
+          support.</P>
+
+          <P>Arnold de Leon (<A href=
+          "mailto:arnold@corp.webtv.net">arnold@corp.webtv.net</A>)
+          then fixed various bugs and added enhancements while at
+          <A href="http://www.synopsys.com/">Synopsys</A>. I then
+          took the result, continued fixing things, and added
+          features we found useful.</P>
+
+          <P><A href="http://www.gnac.com/">GNAC</A> (Global
+          Networking and Computing - currently <A href=
+          "http://www.certaintysolutions.com/">Certainty
+          Solutions</A>) has been supporting my coding efforts (in
+          too many ways to list) since 1996.</P>
+
+          <H3>The conserver.com Distribution</H3>
+
+          <P>The result is a combination of many people's work.
+          This version is being released in hopes that it will help
+          others. There is no warranty or support implied by the
+          distribution of the software.</P>
+
+          <P>So, what the heck is up with all the different
+          conserver versions? Well, the original authors are
+          continuing to distribute their own threads of the
+          software so you have three main threads (as far as I
+          know). First, there's Tom Fine's thread at <A href=
+          "http://hea-www.harvard.edu/~fine/Tech/console-server.html">
+          http://hea-www.harvard.edu/~fine/Tech/console-server.html</A>.
+          He isn't actively developing it, however, according to
+          the website. Next, there's Kevin Braunsdorf's version at
+          <A href=
+          "ftp://ftp.physics.purdue.edu/pub/pundits/">ftp://ftp.physics.purdue.edu/pub/pundits/</A>.
+          Kevin is semi-actively working on his thread. Doesn't
+          look like any new versions have been out since August
+          2000 (version 8.5), but maybe this info will be out of
+          date by the time you read this. Lastly, the conserver.com
+          version is based on Kevin's "5.21-Beta" distribution, but
+          since <B>HEAVILY</B> modified and enhanced (more details
+          in the "Origin" section above).</P>
+
+          <P>If I were looking for a conserver package I would
+          either use Kevin's latest distribution or the
+          conserver.com distribution. Which one? Well, obviously
+          I'm biased and believe the conserver.com distribution
+          should be your choice, but Kevin's does have UPS (serial
+          port line toggling bits) that the conserver.com version
+          doesn't have. What does the conserver.com distribution
+          have? Well, in reality, too many things to list. You'll
+          have to look at the <A href="CHANGES">CHANGES</A> file
+          and see the enhancements, bug fixes, and general
+          development since the original. Don't let the version
+          numbers fool you - you'll have to compare and contrast
+          for yourself.</P>
+
+          <H3>Downloading</H3>
+
+          <P>The current version, released on Dec 2, 2003, is <A
+          href="8.0.8.tar.gz">8.0.8.tar.gz</A>. You can get it via
+          <A href=
+          "ftp://ftp.conserver.com/conserver/8.0.8.tar.gz">FTP</A>
+          or <A href="8.0.8.tar.gz">HTTP</A>. See the <A href=
+          "CHANGES">CHANGES</A> file for information on the latest
+          updates.</P>
+
+          <P>As of version 6.1.7, the packaging and numbering
+          scheme has changed. I used to package conserver as
+          conserver-GNAC-v.vv. Since <A href=
+          "http://www.gnac.com/">GNAC</A> (now <A href=
+          "http://www.certaintysolutions.com/">Certainty
+          Solutions</A>) has changed its name I've decided to drop
+          the GNAC portion and use a three-digit version number
+          (conserver-v.v.v). Why change the version numbering? I
+          need to differentiate this thread of the code from the
+          original authors' and I couldn't come up with a good
+          replacement for the GNAC name - sad, but true.</P>
+
+          <H3>Installation</H3>
+
+          <P>Check the <A href="INSTALL">INSTALL</A> file for

+

+
+          <P>Here's a list of systems that I've been told can
+          successfully compile conserver. If anyone has more to add
+          to this list (or something on the list doesn't work any
+          more), please let me know.</P>

-#
-# lpr this file, you need to read it with other stuff on the screen.
-#
-
-Basic installation:
-
- First off, this stuff isn't guaranteed to work, or compile or anything.
- Second, the Makefile doesn't even really do that much, because most people
- with large networks don't have very normal configurations (that's a lot like
- an excuse :-).  Third, I assume you have the hardware set up done, and don't
- need any help there (just use normal serial lines, or see Sun-serial).
-
- With that out of the way, let's get started.
-
-
-Prep:
-
- If you are a serious kinda guy you will want to add the console service to
- /etc/services, here is the line we use:
-	console		782/tcp		conserver	# console server
-
- Otherwise you'll have to hard code a PORT in cons.h (there are a comments
- at the apropos points.
-
- If you do not have the PUCC ptyd daemon (and I'll bet you don't) you have
- to edit the Makefile, look at the block that sets HAVE_PTYD.
-
- Later, on the console server you will have to add a line to /etc/rc.local,
- or an atboot/cronboot job to start the console server
-	nice --4 /usr/local/etc/conserver >/dev/console 2>&1 </dev/null &
-
- [we run it from roots .profile on an auto-login port.]
-
-
-Compiling:
-
- Save a copy of cons.h and edit the one in this directory to your desires.
- It should be self-explanatory.
-
- Edit Makefile, setting BIN and PROG.
-
- Type "make".  This compiles the server.  If you fail on `XTABS' in
- group.c either change XTABS to TAB3 or #if 0 the block.  I've not
- had time to track this down.
-
- cd ../conserver.cf and follow the INSTALL there.  (Then come back here.)
-
- cd ../console and follow INSTALL there.  (Then come back here.)
-
- If you changed from using /usr/local/{bin,etc} you may want to change the
- "FILES" section in the man page "conserver.8L".
-
- If everything went well, type "make install" in each directory.  You will
- probably need to run this as root, depending on where you're putting stuff.
-
- This only installs things on the local machine (unless you have a kinky
- system configuration).  You will have to distribute at least the client
- program to your other machines.  {Compile on unlike CPU types, of course.}
-
-
-How did we do?
-
- Now run:
-	conserver -V
-
- You should get something like:
-	conserver: $Id: INSTALL,v 4.4 94/07/19 14:48:29 ksb Exp $
-	conserver: default access type `r'
-	conserver: default escape sequence `\005\143'
-	conserver: configuration in `/usr/local/lib/conserver.cf'
-	conserver: limited to 20 groups with 10 members
-	conserver: service name `conserver'
-
-Testing the console server:
-
- To test it (us the dummy config you build in ../conserver.cf) run
-	# conserver -C ../conserve.cf/dummy.cf -v &
-
- You should get an output that looks like:
-	conserver: 1: dumb is on /dev/ttya (9600e) logged to /tmp/dummy.log
-	conserver: group 1 on port 1270
-	conserver: access type 't' for "127.0.0.1"
-	conserver: access type 'a' for "cc.purdue.edu"
-	
- In another login window (or this one, I guess)
-	$ console -vA dumb
- You should get an output like this:
-	console: attach to dumb (on localhost)
-	conserver: dumb: login root@nostromo.cc.purdue.edu
-	Enter `^Ec?' for help.
-	[ok, attached]
-	[replay]
-
- You can type to your device now, and it should answer you.  Use
- ^Ec? for help and ^Ec. to hangup on it.
-
-
-If that worked...
-
- You can check over the real conserver.cf and start a real console server.
- You are set.
-
-
-Details/limits/bugs:
-
- The log files grow without bound.  Move the log files to OLD (with PUCC
- install) and HUP the conserver process to get him to re-open the log files.
- Here is the install cmd we use:
-	install -cq /dev/null /usr/adm/his.console
-
- You might wanna start stamper with the console server, but it doesn't
- re-open log files -- some later version of the console server will assume
- stampers job.

-
-The general idea...
-
- The idea is you have a big network.  You have several machines whose consoles
- you want to access remotely.  You connect the console lines of these machines
- to serial ports on another machine, which runs the server half of this
- software.  Then you can use the client program to get at the consoles from
- anywhere in the network.  It also provides log file of the consoles and
- an operator stream.
-
-
-Who will help me?
-
- Send questions, comments, and bug reports to:
-	ksb@cc.purdue.edu  (Kevin S Braunsdorf)
-	fine@cis.ohio-state.edu (Tom Fine)
-
-Permissions needed to run this?
-
- The console server does not need to be run as root.  As long as it
- has permission to write to all the log files, any id will be fine.
- Keep in mind, though, that log files occasionally end up with
- sensitive data in them (like root passwords when people don't watch
- for the pasword prompt).
-
-
-Console server process management.
-
- The conserver (usually) ends up running several process: one master and
- several children.  Each of the children is responsible for some of the
- consoles.  Occasionally, we've had problems with one of the children becoming
- "stuck" in one sense or another.  To make dealing with this easier here
- is the plan:
-
- 1.  If you need to restart everything, run
-	console -q
-     which will terminate the console server on all master hosts.
-
- 2.  If you need to restart on one host, killing the master process (on
-     that host) with a SIGTERM (the default for kill) will tell the master
-     process to kill everything (including itself).
-
- 3.  If any child dies, the master process will start another one to replace
-     it.  So if you have a process which is "stuck" it is easy to restart.
-     {Send it a TERM and let conserver respawn it.}
-
- 4.  If a console is spewing trash use the down (`d') command to make the
-     server ignore it.  Use the reopen (`o') command to restore it to
-     working order.
-
- 5.  If all else fails get a real tty on a cart and push it to the poor
-     machine :-).  [Keep one handy -- we don't claim this software is
-     any better than any other *FREE* product.]
-
-
-Log file time stamping
-
- We use a simple script like stamper.sh, which we start from rc.local, to
- time-stamp the files from all the machines that don't do this already.
- Using this script has the advantage over crontab entries that it doesn't
- interrupt what is happening on the console, if someone is using it.
-
- Use
-	stamper /usr/adm/target.console /usr/adm/other.console
- to add time stamps to the log file for the `target' and `other' machines.
-
- [ This stamper script will go away someday soon. -- ksb]

 .SH DESCRIPTION
 .B Conserver
-is the daemon for the
-.IR console (1L)
-program.
-It provides remote access to the server consoles,
-and logs all console data.
-Slave hosts which have no current connection might produce important
-error messages; these unloved errors are labeled with a machine name
-and output on stdout.
+is the daemon that manages
+remote access to system consoles by multiple users via the
+.BR console (1)
+client program and logs all console output.
+It can connect to consoles via local serial ports, terminal
+servers that allow network access, or to any external program.
 .PP
-When started, it forks a child for each group in /etc/conserver.cf and
-assigns each process a port number to listen on.  The \fIconsole\fP
-client program communicates with the master console server to find
-the host and port the child is listening on.
+When started,
+.B conserver
+reads its
+.BR conserver.cf (5)
+file for details of each console it should manage,
+including serial port or network parameters and logging options.
+(Also, in environments where multiple servers share a cf file,
+any server is able to refer clients to the particular server
+managing a requested console, so that the client need not have
+knowledge of the distribution of consoles among servers.)
+.B Conserver
+forks a child for each group of consoles it must manage
+and assigns each process a port number to listen on.
+The maximum number of consoles managed by each child process is set using
+.B \-m
+option.
+The
+.BR console (1)
+client program communicates with the master console server process to find
+the port (and host, in a multi-server configuration)
+on which the appropriate child is listening.
+.B Conserver
+restricts connections from clients based on the host access section of its
+.BR conserver.cf (5)
+file, restricts users based on the console access lists of the
+.BR conserver.cf (5)
+file, and authenticates
+users against its
+.BR conserver.passwd (5)
+file.
+.B Conserver
+can also restrict clients using the tcp-wrappers package (enabled
+using
+.BR --with-libwrap ).
+This authentication is done before consulting
+the
+.BR conserver.cf (5)
+access list.
 .PP
 .B Conserver
-completely controls any connection to a controlled host.
-All handling of escape sequenes is done by the server,
-except the suspend sequence which is
-sent as an out-of-band command to the client.
+completely controls any connection to a console.
+All escape sequences given by the user to
+.B console
+are passed to the server without interpretation.
+The server recognizes and processes all escape sequences,
+The suspend sequence is recognized by the server and sent back to the
+client as a TCP out-of-band command, which the client processes.
 .PP
 The
 .B conserver
 parent process will automatically respawn any child process that dies.
-If the parent process receives a SIGTERM, it will propogate the signal
-to its children.
+The following signals are propagated by the parent process to its children.
+.TP 10
+SIGTERM
+Close all connections and exit.
+.TP
+SIGHUP
+Reread the configuration file.
+New consoles are managed by forking off new children, deleted
+consoles (and their clients) are dropped,
+and changes to consoles are done "in place", resetting the console
+port (bringing it down and up) only when necessary.
+The console name is used to determine when consoles
+have been added/removed/changed.
+All actions performed by SIGUSR2 are also performed.
+.TP
+SIGUSR1
+Try to connect to any consoles marked as down.
+This can come in handy if you had a terminal server (or more)
+that wasn't accepting connections at startup and you want
+.B conserver
+to try to reconnect to all those downed ports.
+.TP
+SIGUSR2
+Close and reopen all console logfiles
+and, if in daemon mode
+.RB ( \-d
+option), the error logfile (see the
+.BR \-L
+option).
+All actions performed by SIGUSR1 are also performed.
+.PP
+Consoles which have no current client
+connection might produce important error messages.
+With the
+.B \-u
+option, these ``unloved'' errors are labeled with a machine name
+and output on stdout (or, in daemon mode, to the logfile).
+This allows a live operator or an automated log scanner
+to find otherwise unseen errors by watching in a single location.
+.PP
+.B Conserver
+must be run as root if it is to bind to a port under 1024 or if it
+must read protected password files (like shadow passwords)
+for authentication (see
+.BR conserver.passwd (5)).
+Otherwise, it may be run by any user, with
+.B \-p
+used to specify a port above 1024.
+.PP
+If encryption has been built into the code
+.RB ( --with-openssl ),
+encrypted client connections (without certificate exchanges) happen
+by default.
+To add certificate exchanges, use the
+.B \-c
+option with the client and server.
+For authentication of the certificates to work,
+the signing certificate must be properly trusted, which usually means
+the public portion is in
+.IB OPENSSL_ROOT /ssl/certs
+(on both the client and server sides).
+See the sample self-signing certificate making script
+.B contrib/maketestcerts
+for further clues.
+To allow
+non-encrypted client connections (in addition to encrypted client
+connections), use the
+.B \-E
+option.
 .SH OPTIONS
+.PP
+Options may be given as separate arguments (e.g.,
+.B \-n
+.BR \-d )
+or clustered (e.g.,
+.BR \-nd ).
+Options and their arguments may be separated by optional white space.
+Option arguments containing spaces or other characters special to the shell
+must be quoted.
+.TP 12
+.B \-7
+Strip the high bit off of all data received,
+whether from the
+.B console
+client or from the console device, before any processing occurs.
+.TP
+.BI \-a type
+Set the default access type for incoming connections from
+.B console
+clients:
+.RB ` r '
+for refused (the default),
+.RB ` a '
+for allowed, or
+.RB ` t '
+for trusted.
+This applies to hosts for which no matching entry is found in
+the access section of
+.BR conserver.cf (5).
+.TP
+.BI \-b port
+Set the base port for children to listen on.
+Each child starts looking for free ports at
+.I port
+and working upward, trying a maximum number of ports
+equal to twice the maximum number of groups.
+If no free ports are available in that range,
+.B conserver
+exits.
+By default,
+.B conserver
+lets the operating system choose a free port.
+.TP
+.BI \-c cred
+Load an SSL certificate and key from the PEM encoded file
+.IR cred .
 .TP
 .BI \-C config
-With this option the invoker may specify an alternate confguration.
-The default \fIconfig\fP is /usr/local/lib/conserver.cf.
+Read configuration information from the file
+.IR config .
+The default
+.I config
+may be changed at compile time using the
+.B --with-cffile
+option.
 .TP
 .B \-d
 Become a daemon.
+Disconnects from the controlling terminal and sends
+all output to the logfile (see
+.BR \-L ).
+.TP
+.B \-D
+Enable debugging output, sent to stderr.
+Multiple
+.B \-D
+options increases debug output.
+.TP
+.B \-E
+If encryption has been built into the code
+.RB ( --with-openssl ),
+encrypted client connections are a requirement.
+This option allows non-encrypted clients (as well as encrypted clients) to
+connect to consoles.
+.TP
+.B \-F
+Do not automatically reinitialize failed (unexpectedly closed) consoles.
+If the console is a program (`|' syntax) and it closes with a zero
+exit status, the console is reinitialized regardless of this option.
+Without this option, a console is immediately reopened,
+and if that fails, retried every minute until successful.
+This option has no effect on the
+.B \-o
+and
+.B \-O
+options.
 .TP
 .B \-h
 Output a brief help message.
 .TP
 .B \-i
-Initiate console connections on demand (and close them when not used)
+Initiate console connections on demand (and close them when not used).
+.TP
+.BI \-L logfile
+Log errors and informational messages to
+.I logfile
+after startup in daemon mode
+.RB ( \-d ).
+This option does not apply when not running in daemon mode.
+The default
+.I logfile
+may be changed at compile time using the
+.B --with-logfile
+option.
+.TP
+.BI \-m max
+Set the maximum consoles managed per process.
+The default
+.I max
+may be changed at compile time using the
+.B --with-maxmemb
+option.
+.TP
+.BI \-M addr
+Set the address to listen on.
+This allows conserver to bind to a
+particular IP address (like `127.0.0.1') instead of all interfaces.
+The default is to bind to all addresses.
 .TP
 .B \-n
-The \fIconserver\fP will \fBnot\fP output unloved console output to
-stdout.
+Obsolete (now a no-op); see
+.BR \-u .
+.TP
+.B \-o
+Normally, a client connecting to a ``downed'' console does just that.
+Using this option, the server will automatically attempt to open
+(``bring up'') the console when the client connects.
+.TP
+.BI \-O min
+Enable periodic attempts (every
+.I min
+minutes) to open (``bring up'') all downed
+consoles (similar to sending a SIGUSR1).
+.TP
+.BI \-p port
+Set the TCP port for the master process to listen on.
+This may be either a port number or a service name.
+The default
+.IR port ,
+``conserver'' (typically 782),
+may be changed at compile time using the
+.B --with-port
+option.
+.TP
+.BI \-P passwd
+Read the table of authorized user data from the file
+.IR passwd .
+The default
+.I passwd
+may be changed at compile time using the
+.B --with-pwdfile
+option.
+.TP
+.B \-R
+Disable automatic client redirection to other conserver hosts.
+This
+means informational commands like
+.B \-w
+and
+.B \-i
+will only show the status of the local conserver host and attempts to
+connect to remote consoles will result in an informative message to the user.
+.TP
+.B \-S
+Do not run the server, just perform a syntax check of configuration file and
+exit with a non-zero value if there is an error.
+.TP
+.B \-u
+Send unloved console output to
+.BR conserver 's
+stdout (which, in daemon mode, is redirected to the logfile).
+This applies to all consoles to which no user is attached,
+independent of whether logging of individual consoles is enabled via
+.B conserver.cf
+entries.
+.TP
+.BI \-U logfile
+Copy all console data to the ``unified''
+.IR logfile .
+The output is the same as the
+.B \-u
+output, but all consoles, not
+just those without a user, are logged.
+Each line of output is prefixed with the console name.
+If a user is attached read/write, a `*' is appended to the console name,
+to allow log watching utilites to ignore potential user-introduced alarms.
 .TP
 .B \-v
 Echo the configuration as it is being read (be verbose).
 .TP
 .B \-V
-Output the version of the console server (only) and exit.
+Output the version number and settings of the
+.B conserver
+program and then exit.
+.SH PROTOCOL
+.PP
+The protocol used to interact with the
+.B conserver
+daemon has two basic styles.
+The first style is the initial line-based mode, which occurs before
+connecting to a console.
+The second style is the character-based, escape-sequence mode, while
+connected to a console.
+.PP
+The initial line-based mode begins the same for both the master process
+and it's children.
+Upon a successful (non-rejected) client connection, an ``ok'' is sent.
+The client then issues a command and the server responds to it with a
+result string (``ok'' being the sign of success for most commands).
+The commands available are ``help'', ``ssl'' (if
+SSL was built into the code), ``login'', and ``exit''.
+Using the ``login'' command, the client authenticates and gains access to
+the extended command set.
+This is where the master process and it's children differ.
+The master process gives the client access to global commands, and the
+child provides commands for interacting with the consoles it manages.
+The ``help'' command, in both cases, will provide a complete
+list of commands and a short description of what they do.
+.PP
+The second, character-based, style of interaction occurs when the client
+issues the ``call'' command with a child process.
+This command connects the client to a console and, at that point, relays
+all traffic between the client and the console.
+There is no more command-based interaction between the client and the server,
+any interaction with the server is done with the default escape sequence.
+.PP
+This is, by no means, a complete description of the entire client/server
+interaction.
+It is, however, a brief explanation in order to give a idea of
+what the program does.

-Prep:
-
- Did you do the prep work in ../conserver yet?  If not please start there.
-
-
-Compiling:
-
- Try a
-	make
- in this directory.  If cons.h is correct this should just compile.
-
-
-First test:
-
- Run a version command:
-	./console -V
- and see something like:
-	console: $Id: INSTALL,v 4.1 91/06/19 15:27:49 ksb Exp $
-	console: initial master server `staff.cc.purdue.edu'
-	console: default escape sequence `^Ec'
-	console: loopback address for mentor.cc.purdue.edu is 127.0.0.1
-
-
- Finish the INSTALL in conserver now.
-
-
-Connect to the conserver on your dumb port,
-
- Try all the commands.  Especially ^Ecz and ^Ecd/^Eco.
-
- Try two connections to the same console, note the cool way you can force
- the other guy off (^Ecf).

-BUGS:
-	This program depends on a header file in ../conserver/cons.h,
-	which is dones't know how to make.
-
-What does it do?
-
- The console switch (conserver) uses some tty ports on a `switch machine' to
- read the output of many host machines.  Admins can use a client program
- (console) to connect to any console under control of the `switch'.  Thus from
- my terminal here on the second floor I can control the console for each of
- the machines in the machine room 3 floors below me!
-
- The `switch' host is monitored by an operator who sees all the error output
- from all the consoles (in a xterm here at PUCC).  This operator can call up a
- console on any machine in a flash and respond to problems.  He is aware of
- problems without having to poll many CRTs stacked out in the machine room --
- he and the tape drives can be in a quiet place.
-
-
-What platforms?
-
- It runs under 4.2/4.3bsd, IBM's AIX6000, SunOS 4.X, and HPUX.
- Only the client runs under HPUX at this release.  It depends on
- select(2) and sockets.
-
-
-What do I need to evaluate it?
-
- I believe a modem could be used in a pinch as a `host', anything that you can
- trick into producing tty I/O.  Even a dumb tty, but then you must do the
- echo.  Another port on the same machine was used for testing at one point...
- and an EPROM programmer might even work.
-
-
-Who would be interested in this kind of thing?
-
- Anyone with more than one machine with a glass tty would love it, it also
- gets rid of the need for paper consoles.
-
-
-Is this software restricted in distribution?
-
- Tom has an Ohio State copyright on the stuff, I'm sure that there will be no
- problem with distribution.  {He ripped the Purdue ECN copyright off the code
- he got, I didn't change his.}  Tom has not replied to any of my email in ~3
- months....
-
-
-Why this version rather than any other?
-
- The PUCC version supports many more features (multiple `switch' machines for
- when you run out of ports; job control; down'd consoles, etc) than either the
- Ohio State or Purdue ECN versions.
-
-
-How much trouble is it to port?
-
- The code is ~2000 lines for the server and ~1150 for the client.  Not too
- hard to read in ~3 hours.  It should work with a little push on any BSD type
- UNIX.

 .SH DESCRIPTION
 .B Console
-is used to manipulate console terminals remotely or poll running
-\fIconserver\fP(8L) daemons for status information.
+is used to manipulate console terminals remotely or to poll running
+.BR conserver (8)
+daemons for status information.
+.PP
+In the first form above,
+.B console
+asks the user's password before
+granting interactive access to a console (on a non-trusted system),
+since such a session may provide single-user access.
+Only as much of the console name as is required to
+identify it uniquely to the server is required.
+.PP
+For non-interactive options,
+.B console
+outputs only the requested information and exits.
 .PP
 .B Console
-queries the user for the their passwd before
-granting interactive access to a console (on a non-trusted system)
-since such a session may provide single-user access.
-.PP
-In the non-interactive mode
+knows only of a primary
+.B conserver
+host (see the
+.B \-M
+option below), to which it initially connects.
+In a multi-server environment, the primary server may refer
+the client to a different server handling the requested console,
+or it will provide a list of all servers if required (as when
 .B console
-outputs only the requested information.
+is invoked with the
+.B \-r
+option).
+.B Console
+then opens connections to the appropriate server(s).
+It is not necessary for the user of
+.B console
+to know which server manages which consoles, as long as
+.B console
+knows a valid primary server
+and all available consoles are listed in the primary server's
+configuration file.
 .SH OPTIONS
+.PP
+Options may be given as separate arguments (e.g.,
+.B \-v
+.BR \-w )
+or clustered (e.g.,
+.BR \-vw ).
+Options and their arguments may be separated by optional white space.
+Option arguments containing spaces or other characters special to the shell
+must be quoted.
+.TP 11
+.B \-7

+.IR user @ console .
+You may specify the target as
+.I user
+(disconnect the
+.IR user,
+regardless of what console they are attached to),

 .BI \-e esc
-Set the initial two character escape sequence to
-those represented by \fIesc\fP.
-Any of the forms output by \fIcat\fP(1)'s \-\fBv\fP option
-are accepted.  The default value is ``^Ec''.
+Set the initial two-character escape sequence to those represented by
+.IR esc .
+Any of the forms output by

+.TH CHAT 8 "22 May 1999" "Chat Version 1.22"
+.SH "NAME"
+chat \- Automated conversational script with a modem
+.SH "SYNOPSIS"
+.B chat
+[
+.I options
+]
+.I script
+.SH "DESCRIPTION"
+.LP
+The \fIchat\fR program defines a conversational exchange between the
+computer and the modem. Its primary purpose is to establish the
+connection between the Point-to-Point Protocol Daemon (\fIpppd\fR) and
+the remote's \fIpppd\fR process.
+.SH "OPTIONS"
+.TP
+.B -f \fI<chat file>
+Read the chat script from the chat \fIfile\fR. The use of this option
+is mutually exclusive with the chat script parameters. The user must
+have read access to the file. Multiple lines are permitted in the
+file. Space or horizontal tab characters should be used to separate
+the strings.
+.TP
+.B -t \fI<timeout>
+Set the timeout for the expected string to be received. If the string
+is not received within the time limit then the reply string is not
+sent. An alternate reply may be sent or the script will fail if there
+is no alternate reply string. A failed script will cause the
+\fIchat\fR program to terminate with a non-zero error code.
+.TP
+.B -r \fI<report file>
+Set the file for output of the report strings. If you use the keyword
+\fIREPORT\fR, the resulting strings are written to this file. If this
+option is not used and you still use \fIREPORT\fR keywords, the
+\fIstderr\fR file is used for the report strings.
+.TP
+.B -e
+Start with the echo option turned on. Echoing may also be turned on
+or off at specific points in the chat script by using the \fIECHO\fR
+keyword. When echoing is enabled, all output from the modem is echoed
+to \fIstderr\fR.
+.TP
+.B -E
+Enables environment variable substituion within chat scripts using the
+standard \fI$xxx\fR syntax.
+.TP
+.B -v
+Request that the \fIchat\fR script be executed in a verbose mode. The
+\fIchat\fR program will then log the execution state of the chat
+script as well as all text received from the modem and the output
+strings sent to the modem.  The default is to log through the SYSLOG;
+the logging method may be altered with the -S and -s flags. SYSLOGs
+are logged to facility LOG_LOCAL2.
+.TP
+.B -V
+Request that the \fIchat\fR script be executed in a stderr verbose
+mode. The \fIchat\fR program will then log all text received from the
+modem and the output strings sent to the modem to the stderr device. This
+device is usually the local console at the station running the chat or
+pppd program.
+.TP
+.B -s
+Use stderr.  All log messages from '-v' and all error messages will be
+sent to stderr.
+.TP
+.B -S
+Do not use the SYSLOG.  By default, error messages are sent to the
+SYSLOG.  The use of -S will prevent both log messages from '-v' and
+error messages from being sent to the SYSLOG (to facility LOG_LOCAL2).
+.TP
+.B -T \fI<phone number>
+Pass in an arbitary string, usually a phone number, that will be
+substituted for the \eT substitution metacharacter in a send string.
+.TP
+.B -U \fI<phone number 2>
+Pass in a second string, usually a phone number, that will be
+substituted for the \eU substitution metacharacter in a send string.
+This is useful when dialing an ISDN terminal adapter that requires two
+numbers.
+.TP
+.B script
+If the script is not specified in a file with the \fI-f\fR option then
+the script is included as parameters to the \fIchat\fR program.
+.SH "CHAT SCRIPT"
+.LP
+The \fIchat\fR script defines the communications.
+.LP
+A script consists of one or more "expect-send" pairs of strings,
+separated by spaces, with an optional "subexpect-subsend" string pair,
+separated by a dash as in the following example:
+.IP
+ogin:-BREAK-ogin: ppp ssword: hello2u2
+.LP
+This line indicates that the \fIchat\fR program should expect the string
+"ogin:". If it fails to receive a login prompt within the time interval
+allotted, it is to send a break sequence to the remote and then expect the
+string "ogin:". If the first "ogin:" is received then the break sequence is
+not generated.
+.LP
+Once it received the login prompt the \fIchat\fR program will send the
+string ppp and then expect the prompt "ssword:". When it receives the
+prompt for the password, it will send the password hello2u2.
+.LP
+A carriage return is normally sent following the reply string. It is not
+expected in the "expect" string unless it is specifically requested by using
+the \er character sequence.
+.LP
+The expect sequence should contain only what is needed to identify the
+string. Since it is normally stored on a disk file, it should not contain
+variable information. It is generally not acceptable to look for time
+strings, network identification strings, or other variable pieces of data as
+an expect string.
+.LP
+To help correct for characters which may be corrupted during the initial
+sequence, look for the string "ogin:" rather than "login:". It is possible
+that the leading "l" character may be received in error and you may never
+find the string even though it was sent by the system. For this reason,
+scripts look for "ogin:" rather than "login:" and "ssword:" rather than
+"password:".
+.LP
+A very simple script might look like this:
+.IP
+ogin: ppp ssword: hello2u2
+.LP
+In other words, expect ....ogin:, send ppp, expect ...ssword:, send hello2u2.
+.LP
+In actual practice, simple scripts are rare. At the vary least, you
+should include sub-expect sequences should the original string not be
+received. For example, consider the following script:
+.IP
+ogin:--ogin: ppp ssword: hello2u2
+.LP
+This would be a better script than the simple one used earlier. This would look
+for the same login: prompt, however, if one was not received, a single
+return sequence is sent and then it will look for login: again. Should line
+noise obscure the first login prompt then sending the empty line will
+usually generate a login prompt again.
+.SH "COMMENTS"
+Comments can be embedded in the chat script. A comment is a line which
+starts with the \fB#\fR (hash) character in column 1. Such comment
+lines are just ignored by the chat program. If a '#' character is to
+be expected as the first character of the expect sequence, you should
+quote the expect string, or give its octal value, `\e043'.
+In a script file if you want to wait for a prompt that starts with a '#'
+character, you would have to write something like this:
+.IP
+# Now wait for the prompt and send logout string
+.br
+\'# ' logout
+.SH "SENDING DATA FROM A FILE"
+If the string to send starts with an at sign (@), the rest of the
+string is taken to be the name of a file to read to get the string to
+send.  If the last character of the data read is a newline, it is
+removed.  The file can be a named pipe (or fifo) instead of a regular
+file.  This provides a way for \fBchat\fR to communicate with another
+program, for example, a program to prompt the user and receive a
+password typed in.
+.SH "ABORT STRINGS"
+Many modems will report the status of the call as a string. These
+strings may be \fBCONNECTED\fR or \fBNO CARRIER\fR or \fBBUSY\fR. It
+is often desirable to terminate the script should the modem fail to
+connect to the remote. The difficulty is that a script would not know
+exactly which modem string it may receive. On one attempt, it may
+receive \fBBUSY\fR while the next time it may receive \fBNO CARRIER\fR.
+.LP
+These "abort" strings may be specified in the script using the \fIABORT\fR
+sequence. It is written in the script as in the following example:
+.IP
+ABORT BUSY ABORT 'NO CARRIER' '' ATZ OK ATDT5551212 CONNECT
+.LP
+This sequence will expect nothing; and then send the string ATZ. The
+expected response to this is the string \fIOK\fR. When it receives \fIOK\fR,
+the string ATDT5551212 to dial the telephone. The expected string is
+\fICONNECT\fR. If the string \fICONNECT\fR is received the remainder of the
+script is executed. However, should the modem find a busy telephone, it will
+send the string \fIBUSY\fR. This will cause the string to match the abort
+character sequence. The script will then fail because it found a match to
+the abort string. If it received the string \fINO CARRIER\fR, it will abort
+for the same reason. Either string may be received. Either string will
+terminate the \fIchat\fR script.
+.SH "CLR_ABORT STRINGS"
+This sequence allows for clearing previously set \fBABORT\fR strings.
+\fBABORT\fR strings are kept in an array of a pre-determined size (at
+compilation time); \fBCLR_ABORT\fR will reclaim the space for cleared
+entries so that new strings can use that space.
+.SH "SAY STRINGS"
+The \fBSAY\fR directive allows the script to send strings to the user
+at the terminal via standard error.  If \fBchat\fR is being run by
+pppd, and pppd is running as a daemon (detached from its controlling
+terminal), standard error will normally be redirected to the file
+/etc/ppp/connect-errors.
+.LP
+\fBSAY\fR strings must be enclosed in single or double quotes. If
+carriage return and line feed are needed in the string to be output,
+you must explicitly add them to your string.
+.LP
+The SAY strings could be used to give progress messages in sections of
+the script where you want to have 'ECHO OFF' but still let the user
+know what is happening.  An example is:
+.IP
+ABORT BUSY
+.br
+ECHO OFF
+.br
+SAY "Dialling your ISP...\en"
+.br
+\'' ATDT5551212
+.br
+TIMEOUT 120
+.br
+SAY "Waiting up to 2 minutes for connection ... "
+.br
+CONNECT ''
+.br
+SAY "Connected, now logging in ...\n"
+.br
+ogin: account
+.br
+ssword: pass
+.br
+$ \c
+SAY "Logged in OK ...\n"
+\fIetc ...\fR
+.LP
+This sequence will only present the SAY strings to the user and all
+the details of the script will remain hidden. For example, if the
+above script works, the user will see:
+.IP
+Dialling your ISP...
+.br
+Waiting up to 2 minutes for connection ... Connected, now logging in ...
+.br
+Logged in OK ...
+.LP
+.SH "REPORT STRINGS"
+A \fBreport\fR string is similar to the ABORT string. The difference
+is that the strings, and all characters to the next control character
+such as a carriage return, are written to the report file.
+.LP
+The report strings may be used to isolate the transmission rate of the
+modem's connect string and return the value to the chat user. The
+analysis of the report string logic occurs in conjunction with the
+other string processing such as looking for the expect string. The use
+of the same string for a report and abort sequence is probably not
+very useful, however, it is possible.
+.LP
+The report strings to no change the completion code of the program.
+.LP
+These "report" strings may be specified in the script using the \fIREPORT\fR
+sequence. It is written in the script as in the following example:
+.IP
+REPORT CONNECT ABORT BUSY '' ATDT5551212 CONNECT '' ogin: account
+.LP
+This sequence will expect nothing; and then send the string
+ATDT5551212 to dial the telephone. The expected string is
+\fICONNECT\fR. If the string \fICONNECT\fR is received the remainder
+of the script is executed. In addition the program will write to the
+expect-file the string "CONNECT" plus any characters which follow it
+such as the connection rate.
+.SH "CLR_REPORT STRINGS"
+This sequence allows for clearing previously set \fBREPORT\fR strings.
+\fBREPORT\fR strings are kept in an array of a pre-determined size (at
+compilation time); \fBCLR_REPORT\fR will reclaim the space for cleared
+entries so that new strings can use that space.
+.SH "ECHO"
+The echo options controls whether the output from the modem is echoed
+to \fIstderr\fR. This option may be set with the \fI-e\fR option, but
+it can also be controlled by the \fIECHO\fR keyword. The "expect-send"
+pair \fIECHO\fR \fION\fR enables echoing, and \fIECHO\fR \fIOFF\fR
+disables it. With this keyword you can select which parts of the
+conversation should be visible. For instance, with the following
+script:
+.IP
+ABORT   'BUSY'
+.br
+ABORT   'NO CARRIER'
+.br
+''      ATZ
+.br
+OK\er\en  ATD1234567
+.br
+\er\en    \ec
+.br
+ECHO    ON
+.br
+CONNECT \ec
+.br
+ogin:   account
+.LP
+all output resulting from modem configuration and dialing is not visible,
+but starting with the \fICONNECT\fR (or \fIBUSY\fR) message, everything
+will be echoed.
+.SH "HANGUP"
+The HANGUP options control whether a modem hangup should be considered
+as an error or not.  This option is useful in scripts for dialling
+systems which will hang up and call your system back.  The HANGUP
+options can be \fBON\fR or \fBOFF\fR.
+.br
+When HANGUP is set OFF and the modem hangs up (e.g., after the first
+stage of logging in to a callback system), \fBchat\fR will continue
+running the script (e.g., waiting for the incoming call and second
+stage login prompt). As soon as the incoming call is connected, you
+should use the \fBHANGUP ON\fR directive to reinstall normal hang up
+signal behavior.  Here is an (simple) example script:
+.IP
+ABORT   'BUSY'
+.br
+''      ATZ
+.br
+OK\er\en  ATD1234567
+.br
+\er\en    \ec
+.br
+CONNECT \ec
+.br
+\'Callback login:' call_back_ID
+.br
+HANGUP OFF
+.br
+ABORT "Bad Login"
+.br
+\'Callback Password:' Call_back_password
+.br
+TIMEOUT 120
+.br
+CONNECT \ec
+.br
+HANGUP ON
+.br
+ABORT "NO CARRIER"
+.br
+ogin:--BREAK--ogin: real_account
+.br
+\fIetc ...\fR
+.LP
+.SH "TIMEOUT"
+The initial timeout value is 45 seconds. This may be changed using the \fB-t\fR
+parameter.
+.LP
+To change the timeout value for the next expect string, the following
+example may be used:
+.IP
+ATZ OK ATDT5551212 CONNECT TIMEOUT 10 ogin:--ogin: TIMEOUT 5 assword: hello2u2
+.LP
+This will change the timeout to 10 seconds when it expects the login:
+prompt. The timeout is then changed to 5 seconds when it looks for the
+password prompt.
+.LP
+The timeout, once changed, remains in effect until it is changed again.
+.SH "SENDING EOT"
+The special reply string of \fIEOT\fR indicates that the chat program
+should send an EOT character to the remote. This is normally the
+End-of-file character sequence. A return character is not sent
+following the EOT.
+.PR
+The EOT sequence may be embedded into the send string using the
+sequence \fI^D\fR.
+.SH "GENERATING BREAK"
+The special reply string of \fIBREAK\fR will cause a break condition
+to be sent. The break is a special signal on the transmitter. The
+normal processing on the receiver is to change the transmission rate.
+It may be used to cycle through the available transmission rates on
+the remote until you are able to receive a valid login prompt.
+.PR
+The break sequence may be embedded into the send string using the
+\fI\eK\fR sequence.
+.SH "ESCAPE SEQUENCES"
+The expect and reply strings may contain escape sequences. All of the
+sequences are legal in the reply string. Many are legal in the expect.
+Those which are not valid in the expect sequence are so indicated.
+.TP
+.B ''
+Expects or sends a null string. If you send a null string then it will still
+send the return character. This sequence may either be a pair of apostrophe
+or quote characters.
+.TP
+.B \eb
+represents a backspace character.
+.TP
+.B \ec
+Suppresses the newline at the end of the reply string. This is the only
+method to send a string without a trailing return character. It must
+be at the end of the send string. For example,
+the sequence hello\ec will simply send the characters h, e, l, l, o.
+.I (not valid in expect.)
+.TP
+.B \ed
+Delay for one second. The program uses sleep(1) which will delay to a
+maximum of one second.
+.I (not valid in expect.)
+.TP
+.B \eK
+Insert a BREAK
+.I (not valid in expect.)
+.TP
+.B \en
+Send a newline or linefeed character.
+.TP
+.B \eN
+Send a null character. The same sequence may be represented by \e0.
+.I (not valid in expect.)
+.TP
+.B \ep
+Pause for a fraction of a second. The delay is 1/10th of a second.
+.I (not valid in expect.)
+.TP
+.B \eq
+Suppress writing the string to the SYSLOG. The string ?????? is
+written to the log in its place.
+.I (not valid in expect.)
+.TP
+.B \er
+Send or expect a carriage return.
+.TP
+.B \es
+Represents a space character in the string. This may be used when it
+is not desirable to quote the strings which contains spaces. The
+sequence 'HI\ TIM' and HI\esTIM are the same.
+.TP
+.B \et
+Send or expect a tab character.
+.TP
+.B \eT
+Send the phone number string as specified with the \fI-T\fR option
+.I (not valid in expect.)
+.TP
+.B \eU
+Send the phone number 2 string as specified with the \fI-U\fR option
+.I (not valid in expect.)
+.TP
+.B \e\e
+Send or expect a backslash character.
+.TP
+.B \eddd
+Collapse the octal digits (ddd) into a single ASCII character and send that
+character.
+.I (some characters are not valid in expect.)
+.TP
+.B \^^C
+Substitute the sequence with the control character represented by C.
+For example, the character DC1 (17) is shown as \^^Q.
+.I (some characters are not valid in expect.)
+.SH "ENVIRONMENT VARIABLES"
+Environment variables are available within chat scripts, if  the \fI-E\fR
+option was specified in the command line. The metacharacter \fI$\fR is used
+to introduce the name of the environment variable to substitute. If the
+substition fails, because the requested environment variable is not set,
+\fInothing\fR is replaced for the variable.
+.SH "TERMINATION CODES"
+The \fIchat\fR program will terminate with the following completion
+codes.
+.TP
+.B 0
+The normal termination of the program. This indicates that the script
+was executed without error to the normal conclusion.
+.TP
+.B 1
+One or more of the parameters are invalid or an expect string was too
+large for the internal buffers. This indicates that the program as not
+properly executed.
+.TP
+.B 2
+An error occurred during the execution of the program. This may be due
+to a read or write operation failing for some reason or chat receiving
+a signal such as SIGINT.
+.TP
+.B 3
+A timeout event occurred when there was an \fIexpect\fR string without
+having a "-subsend" string. This may mean that you did not program the
+script correctly for the condition or that some unexpected event has
+occurred and the expected string could not be found.
+.TP
+.B 4
+The first string marked as an \fIABORT\fR condition occurred.
+.TP
+.B 5
+The second string marked as an \fIABORT\fR condition occurred.
+.TP
+.B 6
+The third string marked as an \fIABORT\fR condition occurred.
+.TP
+.B 7
+The fourth string marked as an \fIABORT\fR condition occurred.
+.TP
+.B ...
+The other termination codes are also strings marked as an \fIABORT\fR
+condition.
+.LP
+Using the termination code, it is possible to determine which event
+terminated the script. It is possible to decide if the string "BUSY"
+was received from the modem as opposed to "NO DIAL TONE". While the
+first event may be retried, the second will probably have little
+chance of succeeding during a retry.
+.SH "SEE ALSO"
+Additional information about \fIchat\fR scripts may be found with UUCP
+documentation. The \fIchat\fR script was taken from the ideas proposed
+by the scripts used by the \fIuucico\fR program.
+.LP
+uucp(1), uucico(8)
+.SH "COPYRIGHT"
+The \fIchat\fR program is in public domain. This is not the GNU public
+license. If it breaks then you get to keep both pieces.

+%description
+Conserver is an application that allows multiple users to watch a
+serial console at the same time.  It can log the data, allows users to
+take write-access of a console (one at a time), and has a variety of
+bells and whistles to accentuate that basic functionality.
