+				Conserver FAQ
+				=============
+
+This is the Conserver FAQ.  Any suggestions/corrections/etc should be
+directed to faq@conserver.com.  The FAQ answers the following questions:
+
+    1) What is conserver?
+    2) Where can I find the software?
+    3) How do I deal with these serial ports?
+    4) How can I tell what compile-time defaults were used?
+    5) What does "conserver: getservbyname: conserver: No such file or
+       directory" mean (or something close to that)?
+    6) What does "console: gethostbyname: console: host lookup error"
+       mean (or something close to that)?
+    7) How do I set up a serial port for no parity?
+    8) Is "Conserver" a Trademark or Registered Trademark?
+    9) When I connect to a console, it says it is down.  Why?
+   10) Is there a technical reason why --with-maxmemb's default is 16?
+       I've changed mine to 96.
+   99) OK, things just don't seem to work.  Help?!?
+
+
+ 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.
+
+ 2) Where can I find the software?
+
+    The latest version can be found at http://www.conserver.com/
+
+ 3) How do I wire/hook up serial ports?
+
+    David "Zonker" Harris has a wonderful set of pages that talk about
+    hooking up many types of terminal servers, equipment, etc.  It also
+    provides links to other serial port references.  You can find his
+    pages at http://www.conserver.com/consoles/.
+
+    Celeste Stokely also has a wealth of references at
+    http://www.stokely.com/.  Just look around and be amazed at what
+    you'll find!
+
+ 4) How can I tell what compile-time defaults were used?
+
+    The compile-time defaults can be found by running conserver and
+    console with the -V flag.  Simple as that.
+
+ 5) What does "conserver: getservbyname: conserver: No such file or
+    directory" mean (or something close to that)?
+
+    When conserver was compiled, it was told to use the /etc/services
+    entry of "conserver" (what came after getservbyname:).  You'll need
+    to either recompile conserver and hard-code a port number (using
+    --with-port=<num>) or enter "conserver" in /etc/services.
+
+ 6) What does "console: gethostbyname: console: host lookup error"
+    mean (or something close to that)?
+
+    When the console command was compiled, it was told to use the
+    hostname "console" (what came after gethostbyname:) as the master
+    conserver host.  You'll need to either reconfigure with the
+    appropriate name of your conserver host (--with-master=<name>) or
+    add an alias of "console".  In most cases, adding an alias is my
+    suggestion.
+
+ 7) How do I set up a local serial port for 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 8.1.3
+	- The '^Ec;' sequence won't work correctly with 8.1.2 (where it
+	  was introduced).
+
+    Version 8.1.2
+	- The 'devicesubst' and 'execsubst' formats have changed from
+	  8.1.1.  It's fairly simple to update your config file to the
+	  new format...just check the conserver.cf manpage.  Sorry for
+	  having to change things, but it's for a good reason (I should
+	  have though ahead when designing the original format).
+
+    Version 8.1.0
+
+	- The client/server protocol has changed to better protect 8-bit
+	  data and to allow programs invoked with '^Ec|' not have to
+	  worry about accidentally sending the escape sequence to the
+	  server.  Though it will look like things are mostly
+	  backward-compatible, don't count on it and just upgrade.
+
+    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.

-    - Now run 'make'.  If you're platform is supported you'll get a nice
-      message about "Configuring for ..." and the programs should compile.
-      If not, you'll have to adjust the settings, or slightly worse,
-      port the software.  For adjusting the settings (like using a
-      different compiler or something), check out the .settings file.
-      'make config', which is done for you, symlinks it to port/<ostype>.
-      If you have to port the software, follow the instructions you
-      received.
+      Not surprisingly, some match the old conserver/cons.h items...here
+      they are for reference:
 
-    - Once things build, you can run 'make install install.man'.
-      This will put things into the /usr/local tree.  If you'd like
-      things deposited elsewhere, you can use 'make PREFIX=/your/path
-      install install.man'.  We like to use something like 'make
-      PREFIX=/tools/conserver install install.man'.
+        PORT or SERVICE         - Socket used to communicate
+        HOST                    - Hostname of console server
+        CONFIG                  - Config file path
+        PASSWD_FILE             - Password file path
+        MAXMEMB                 - Number of consoles per child process
+
+      A couple of notes.  First, --with-libwrap will add tcp_wrappers
+      lookups to all socket connections in the server.  --with-openssl
+      will add encryption between the client and server when you connect
+      to a console.  --with-uds will cause the client and server to use
+      unix domain sockets for their communication, eliminating the
+      tcp communication they normally do (which means --with-master and
+      --with-port are not used).  --with-dmalloc should only be used to
+      do memory allocation debugging and not used in production.
+
+    - Run './configure'.  This will detect system specific
+      information.  The --prefix option will redirect where things are
+      installed.  Other options are available as well...try
+      './configure --help'.
+
+    - Now run 'make'.  Hopefully things will compile.
+
+    - To test your binaries, run 'make test'.  If there are problems, it
+      should mean something is wrong, but check the output differences
+      to make sure it wasn't a temporary failure.  I tried to make the
+      tests generic, but I may have missed something.

+    - Once things build, you can run 'make install'.
+
+    - If you'd like to build the autologin application, you'll need to
+      run 'make autologin'.  If you'd like it installed, use 'make
+      autologin.install'.
 
     - Now that the binaries are in place, we need to set up the
       configuration files and such.
 
-      If you used a blank cons.h file or defined a service name (SERVICE
-      token above), you'll need to enter a definition in your services
-      file (directly, via NIS, or whatever).  Here's what we use:
+      + Does your conserver master hostname exist?  This is the
+        hostname specified with the --with-master option.  By default
+        the hostname is "console", so make sure it's in DNS, hosts
+        files, or whatever.
 
-	    console      782/tcp      conserver    # console server
+      + If you used a symbolic name for the --with-port option (by
+        default it uses "conserver", so the answer would be yes),
+        you'll need to enter a definition in your services file
+        (directly, via NIS, or whatever).  Here's what we use:
 
-      If you defined PORT, you shouldn't have to worry about this step.
+            console      782/tcp    conserver    # console server
 
-      Next, make sure conserver runs during boot.  The init script
-      we use under Solaris is installed in <PREFIX>/etc/conserver.rc.
-      Use that or some form of it for your own /etc/init.d script or an
-      entry in startup files (/etc/rc, /etc/rc.local, or whatever).
+        If you used a number, you shouldn't have to worry about this
+        step.
 
-      Now for the fun stuff.  You need to create a conserver.cf and
-      conserver.passwd file.  Those are defined with the CONFIG and
-      PASSWD_FILE settings.  If you ever need to know what values
-      were compiled into conserver, run 'conserver -V'.  See the
-      conserver.cf/INSTALL file for instructions on setup of these files.
+      + Next, make sure conserver runs during boot.  The init script we
+	use under Solaris is installed in
+	<DATADIR>/examples/conserver/conserver.rc.  Use that or some

     - That's it!  Just start up the console server and enjoy!

+Other Information And Gotchas
+
+    - 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.

+License Clarification
+=====================
+
+The licenses attached to this software ([LICENSES](LICENSES)) are supposed
+to paint a simple concept: that this software was built for the open source
+community and they result in a license compatible with [LICENSE](LICENSE).
+
+Unfortunately, the real world steps in and troubles can arise.  This note
+has been moved over from the [INSTALL](INSTALL) file:
+
+    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).
+
+Here's a copy of the message I exchanged with Thomas A. Fine (original
+author at OSU) in 2001 that is referenced above:
+
+    Date: Wed, 27 Jun 2001 19:47:18 -0400 (EDT)
+    To: bryan@conserver.com
+    From: "Thomas A. Fine" <fine@head-cfa.harvard.edu>
+    Subject: Re: A conserver license question...

+    
+    Well, if I knew then what I know now, I would have copyrighted it
+    under my own name, and not under OSU, and then I could change it.
+    Since I don't work there anymore, strictly speaking, I can't change
+    it.
+    
+    However, IMHO, this license allows modifications, without explicitly
+    stating it.  I can state without a doubt that this was my intention
+    at the time (and hence, OSU's intention, since I put in the copyright
+    while working for OSU).
+    
+    But also, since it allows use of the source, and since the statement
+    required for inclusion says "includes software ..." it seems pretty
+    clear that modification was both allowed and expected.  You can't
+    really use sources if you aren't changing them, and you certainly
+    can't include this software in some other product without making
+    modifications.
+    
+    As I recall, I more or less used the copyright that Berkeley was using
+    back then for there BSD-related software, so I'm surprised there's a
+    problem with it.
+    
+    I have to point out that version 1.2, available at
+    http://hea-www.harvard.edu/~fine/Tech/cs1.2/
+    is distributed entirely without copyright notices.  Interesting, no?
+    So I guess I could add a copyright notice to that.  But would I then
+    be violating the OSU copyright that I wrote for 1.1?  Since it is
+    a different version, I could probably write a new copyright notice 
+    and license and be free and clear.
+    
+    There's also Purdue's versions of the software.  It's mentioned on my
+    console server web page at
+    http://hea-www.harvard.edu/~fine/Tech/console-server.html
+    
+    So, pass this on to the people you're working with and let me know how
+    you want to proceed.
+

+    > So, it's more the lack of explicitly stating the code can be
+    > modified.
+    
+    Since then I talked to one of RedHat's lawyers and they mentioned that
+    they have dealt with this problem too and also concluded that these
+    licenses were intended to cover modification. The current wording of
+    the initial part of the BSD license reflects an attempt to correct an
+    earlier mistake (i.e. someone pointed out the error and Berkeley added
+    "with or without modification"). Also the anti-endorsement clause
+    implies a right to modify.
+
+Hopefully corporations (or, I suppose, their lawyers) will be happy with the
+explanation above and become comfortable with the stated license.

PROTOCOL

@@ -0,0 +1,302 @@
+			   Conserver Protocol
+			   ==================
+
+
+What Is This?
+-------------
+
+The following is an attempt to describe the client/server protocol used
+between the server (conserver) and the client (console).  This document
+bases its information on conserver version 8.1.4, as it's the release
+currently available.  If there are changes to the client/server
+protocol, the INSTALL file should reference them and, ideally, this
+document will be updated.
+
+The information is looked at from the point of the server, since it's
+the server that controls all information and triggers actions on the
+client (like a suspend).  The client's perspective should be obvious
+from this information.
+
+
+SSL
+---
+
+The client and server can negotiate an SSL connection.  As far as the
+code is concerned, the SSL "layer" is transparent.  Data is sent and
+received just as if it was unencrypted.  Therefore, aside bringing up
+the SSL connection, the SSL bits are unimportant from a protocol
+standpoint.  The client and server still send and receive the same
+information - it just happens to be encrypted to everyone else.
+
+
+"On-The-Wire" Data
+------------------
+
+The low-level, "on-the-wire" data is encapsulated similar to the telnet
+protocol.  All data is sent "as-is" with the exception of 0xFF.  0xFF is
+used as a "command character" and both the client and server expect to
+see a predefined option after it.  The possible options are: 0xFF, 'E',
+'G', 'Z', and '.'.
+
+The 0xFF option says to use the literal character 0xFF.  So, if there is
+a 0xFF character in the data stream to be sent, the code will send two
+0xFF characters (it's similar to using '\\' in C strings to embed a
+'\').
+
+The other options are used in various contexts, which will be described
+in detail below.
+
+
+Life As A Server
+----------------
+
+There are three different interfaces presented to clients by the server.
+I'm going to name the three modes "master", "group", and "console".  The
+first two are line-based, and the third is character-based.
+
+To understand the differences, I must outline how conserver manages
+consoles.  When conserver starts, it reads the configuration file,
+listens on the master socket, and, for each group of consoles it must
+manage (where the group size is set by -m), it forks off a copy of
+itself.  Those child processes are what actually connect to the consoles
+and they each listen on a new socket for client connections.  So, you
+end up with a parent process (that knows about all consoles) that
+manages the child processes (that know only about consoles it manages),
+and everyone is listening on an individual socket for connections from
+clients.
+
+The parent process interacts with clients in "master" mode.  That mode
+expects line-based commands and responds similarly.  Because it's the
+master, it understands a certain set of commands that are different than
+in "group" mode.
+
+The child processes interact with clients in "group" mode first, and
+negotiate a change to "console" mode when a client requests a connection
+to a specific console.
+
+
+"master" Mode
+-------------
+
+When parent process gets a connection from a client, it either sends an
+"ok" string to signal it's ready or an error message (like "access from
+your host is refused") and the connection is dropped.  At this point,
+there are a small number of commands recognized by the server, since
+most are restricted to "logged in" clients.  Here's the list of
+available commands:
+
+    exit   disconnect
+    help   this help message
+    login  log in
+    ssl    start ssl session
+
+An "exit" is sent a "goodbye" response and the connection is dropped.  A
+"help" is sent the list above.  A "ssl" is sent an "ok" response and
+then the server expects the client to negotiate an ssl connection.  A
+"login" requires one argument (the username) and is either sent an "ok",
+meaning the client is logged in, or a "passwd?" followed by the local
+hostname, asking for the user's password, which it expects next.  If the
+client sends a valid password, an "ok" is sent, otherwise an error
+message and the connection is dropped.
+
+Upon successful login, the commands available are:
+
+    call      provide port for given console
+    exit      disconnect
+    groups    provide ports for group leaders
+    help      this help message
+    master    provide a list of master servers
+    newlogs*  close and open all logfiles (SIGUSR2)
+    pid       provide pid of master process
+    quit*     terminate conserver (SIGTERM)
+    restart*  restart conserver (SIGHUP) - deprecated
+    reconfig* reread config file (SIGHUP)
+    version   provide version info for server
+    up*       bring up all downed consoles (SIGUSR1)
+    * = requires admin privileges
+
+"exit" and "help" are the same as before the client logged login.
+
+The "call" command expects one argument, the console name to connect to.
+The server will respond with either a port number (if it's a locally
+managed console), an "@hostname" where hostname is the name of the
+remote conserver host managing the console (if it's a remotely managed
+console), or an error message (possibly multi-line).  The client is not
+disconnected, whatever the response.
+
+The "groups" command responds with a colon-separated list of port
+numbers, which correspond to each of the child processes running on the
+local host.  The client is not disconnected.
+
+The "master" command responds with a colon-separated list of "@hostname"
+names.  The list includes any hosts (including the possibility of the
+local host) which have locally managed consoles.  The client is not
+disconnected.
+
+The "newlogs" command reopens all logfiles used by conserver, assuming
+the user has administrative access.  It responds with a message starting
+with "ok" if successful and an error message otherwise (like
+"unauthorized command").  The client is disconnected if it's successful.
+
+The "pid" command responds with the pid of the master process (in this
+case, the one the client is talking to).  The client is not
+disconnected.
+
+The "quit" command will shut down conserver, assuming the user has
+administrative access.  It responds with a message starting with "ok" if
+successful and an error message otherwise (like "unauthorized command").
+The client is disconnected if it's successful.
+
+The "restart" command has been deprecated.  You should use "reconfig".
+
+The "reconfig" command will cause conserver to reread the configuration
+file and apply any changes, assuming the user has administrative access.
+It responds with a message starting with "ok" if successful and an error
+message otherwise (like "unauthorized command").  The client is not
+disconnected.
+
+The "version" command responds with the version string.  The client is
+not disconnected.
+
+The "up" command tries to "bring up" all disconnected consoles, assuming
+the user has administrative access.  It responds with a message starting
+with "ok" if successful and an error message otherwise (like
+"unauthorized command").  The client is disconnected if it's successful.
+
+
+"group" Mode
+------------
+
+When a child process gets a connection from a client, it either sends an
+"ok" string to signal it's ready or an error message (like "access from
+your host is refused") and the connection is dropped.  At this point,
+"group" mode acts just like "master" mode.  Once the client successfully
+logs in, however, "group" mode has the recognizes the following
+commands:
+
+    broadcast    send broadcast message
+    call         connect to given console
+    disconnect*  disconnect the given user(s)
+    examine      examine port and baud rates
+    exit         disconnect
+    group        show users in this group
+    help         this help message
+    hosts        show host status and user
+    info         show console information
+    textmsg      send a text message
+    * = requires admin privileges
+
+The "exit" and "help" commands are like the others documented above.
+
+The "broadcast" command expects a text string of the message to be sent
+to all users connected to this process.  An "ok" is sent as a response.
+
+The "call" command expects one argument, the console name to connect to,
+just like in "master" mode.  The difference here is that this requests
+the server to attach the client to the console and go into "console"
+mode.  If the attachment is successful, the response will begin with a
+'[' character.  If not, an error message is returned.  The success
+responses are:
+
+    [console is read-only]	 - console is read only
+    [read-only -- initializing]	 - console is initializing, and
+				   read-only for the time being
+    [line to console is down]	 - console is down
+    [attached]			 - attached read-write
+    [spy]			 - attached read-only
+
+
+The "disconnect" command expects an argument of the form "user@console"
+where either the "user" or "@console" part may be omitted.  Upon
+success, a response of the form "ok -- disconnected X users" is sent,
+where X is the number of users disconnected.  If a user is unauthorized
+or some other problem occurs, an error message (like "unauthorized
+command") is sent.
+
+The "examine" command returns a list of console information of the form
+that 'console -x' shows.
+
+The "group" command returns a list of console information of the form
+that 'console -w' shows.
+
+The "hosts" command returns a list of console information of the form
+that 'console -u' shows.
+
+The "info" command returns a list of console information of the form
+that 'console -i' shows.
+
+The "textmsg" command expects two arguments, the first being the
+recipient of the message in the form "user@console" (again, where the
+"user" or "@console" portion may be omitted) and the second being the
+string, like the "broadcast" command.  The server returns "ok".
+
+
+"console" Mode
+--------------
+
+As mentioned above, "console" mode is obtained by using the "call"
+command when connected to a child processes operating in "group" mode.
+
+"console" mode should look very familiar to a user of conserver, as it's
+what the user interacts with when connected to a console.  There's
+really nothings special here.  Each character received from the client
+is compared to the escape sequence, and if it matches, an action occurs
+on the server side.  If it doesn't match the escape sequence, the data
+is sent on to the console.  All data received from the console is sent
+to the client(s).  Of course, there are certain exceptions to these
+rules, based on the state of the console and the state of the client.
+And, certain escape sequences cause special behaviors to occur.
+
+Most escape sequences cause the server to send information back to the
+user.  Stuff like "^Ecw", "^Eci", and "^Ecu" are examples.  The escape
+sequence is absorbed by the server, the server sends the client a
+variety of information, and things continue as before.
+
+The more "interesting" escape sequences are the following.
+
+"^Ec;"  The server sends a 0xFF,'G' command sequence to the client, to
+	signal a wish to move to a new console.  The client then gets
+	put into the same state as the "^Ecz" sequence (paused), which
+	gives the client a chance to either resume the connection or
+	disconnect.
+
+"^Ec|"  The server sends a 0xFF,'E' command sequence to the client, to
+	signal a wish to have the client program interact with a
+	program, as opposed to the user.  The server discards all data
+	until it receives one of the following command sequences from
+	the client:
+
+	    0xFF,'E'	Signals successful redirection of interaction to
+			a program.  The server then responds with "[rw]"
+			or "[ro]" to tell the client whether or not they
+			have read-write access.  If not, the client
+			should abort the program and send the abort
+			command sequence below, as other data received by
+			the server will just get dropped.
+
+	    0xFF,'.'	Abort the operation.  The server assumes the
+			redirection didn't happen and returns the client
+			to it's normal mode.
+
+	The server keeps the client in the "redirected" state until it
+	receives a 0xFF,'.' command sequence from the client (which
+	usually occurs when the client command terminates).
+
+	If the client is "bumped" from read-write to read-only by
+	another user, the server will send the client a 0xFF,'.' command
+	sequence to tell it to abort the redirection and return control
+	back to the user.
+
+"^Ecz"  The server sends a 0xFF,'Z' command sequence to the client, to
+	signal a wish to suspend to client process.  The client is then
+	put into a "paused" state where it receives no more data from
+	the server.  When the client is ready to resume receiving data,
+	it sends a character of data to the server, at which point the
+	server discards the character and sends back a status message of
+	the form " -- MSG]".  The current set of possible messages are:
+
+	    " -- line down]"
+	    " -- read-only]"
+	    " -- attached (nologging)]"
+	    " -- attached]"
+	    " -- spy mode]"

-
-    The console server software found here is a heavily modified version
-    originally written by Tom Fine (fine@cis.ohio-state.edu) and then
-    Kevin S Braunsdorf (ksb@cc.purdue.edu).  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.
-
-
-The GNAC Version
-
-    The result is a combination of many people's work.  We (GNAC)

+Conserver
+=========
+
+[![Build Status](https://api.cirrus-ci.com/github/bstansell/conserver.svg)](https://cirrus-ci.com/github/bstansell/conserver)
+
+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.

+
+Bryan Stansell
+
+---------------------------------------------------------------------------
+
+- Telnet protocol should be improved
+    - Not even RFC 854 compliant...or maybe it is (as of 8.1.0)
+    - Option negotiation semi-ignored - should we negotiate anything more?
+    - Others?
+
+- 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
+    - sample conserver.cf has some...but it's not explained well
+
+- 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
+    - actually, ^Ec| does work right with 8.1.0...one change that might
+      be nice is the ability to NOT watch the i/o pass to the local
+      command - try sending a big file to the local host with xmodem.
+
+- autologout?  setting per console?  gack, would have to interpret data.
+    - this will never happen...i don't want 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.
+    - this does work, using the 'initcmd' option, so, all done?
+
+- cyclades ts1000/2000 port : "Moses, Joel" <jmoses@deloitte.com>
+
+- 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?
+    - this may never happen...does anyone really need it?
+
+- 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
+	- i think the -i output covers it, but maybe not
+
+- 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>
+    - not even sure if this is possible w/o confusing the client,
+      but maybe with the new 8.1.0 client-server protocol, we can!
+
+- log rotation by date : Tom Pachla <tom.pachla@nlc-bnc.ca>
+
+- strict file permission checks on conserver.passwd/conserver.cf : Erik
+  Sjolund <erik.sjolund@sbc.su.se>
+
+- netgroup support?  : Nikolaos Papavassiliou
+  <Nikolaos.Papavassiliou@reuters.com> and Phil Dibowitz <phil@usc.edu>
+
+- send sequences to console on client connect? (to repaint screen,
+  for example) : John Cagle <jcagle@gmail.com>
+
+- uucp locks : Sebastian Zagrodzki <sebek@heron.net.icm.edu.pl>
+
+- support more than 9 break sequences : Danish Mirza <Danish@lehman.com>
+  thought it was easy, but adding more than could break things with
+  current encoding.  doable, will have to think harder about it.
+
+- reintroduce console grouping : Martin Turba
+  <martin.turba@igd.fraunhofer.de>
+
+- quick-recheck of down consoles (for uds) and possibly only log state
+  changes (instead of each try) : DJ Gregor <dj@gregor.com>

-.B Conserver.cf
-is the configuration file for
-.IR conserver (8L).
-All lines starting with the pound sign `#' are considered comment lines.
-Blank lines are ignored.
-.PP
-The first section of the file has lines that are separated into
-six colon-separated fields:
-.PP
-\fIserver\fP name - this doesn't have to be the name of the server;
-it is used to refer to the server when using the console program.
-.PP
-\fIdevice\fP file name - the full path name of the device for this server.
-The \fIbaud\fP rate is the speed and parity for this console.
-Speed may be given as an integer,
-parity only requires the first letter of any of: even, odd, mark, space.
-the conserver will send connections for this server to \fIconserver\fP.
-.PP
-!\fIhost\fP - the hostname of the server to connect to.
-A socket connection will be made to port \fIport\fP (an integer).
-.PP
-|\fIcommand\fP - the command to invoke on the console server.

-the conserver will send connections for this server to \fIconserver\fP.
-.PP
-\fIlogfile\fP - the full path name of file where all output from
-this server is logged.  Any occurance of `&' will be replaced with
-the \fIserver\fP name.  Any path that doesn't begin with a `/' will
-have \fIlogdirectory\fP (value of LOGDIR) prepended to it.
-.PP
-\fImark-interval\fP[\fIm|h|d\fP] - specifies the time between
-timestamps applied to the console log file.  The timestamps look like
-`[-- MARK -- Mon Jan 25 14:46:56 PST 1999]'.
-.PP
-This section is terminated with a `%%' token on a line by itself.
-.PP
-The next section of the file contains a list of hosts and addresses
-which are allowed to connect to the console server.  Three levels
-of access all allowed, ``trust'', ``allow'',
-and ``refuse''.
-The access modifier is followed by a colon and a list of addresses or
-host names.
-Any complete suffix of a host name my be used to allow access for all hosts
-in that subdomain.
-For example `cc.purdue.edu' will allow `mentor.cc.purdue.edu'
-and `mace.cc.purdue.edu', but not `pucc.purdue.edu' or `hack.purdue.edu'.
-For IP addresses, optional netmasks may be specified.  For example `192.168.1.0'
-will allow the class C space of 192.168.1.0.  `192.168.1.0/25' will only allow
-only the lower half of that same address space (192.168.1.0 thru 192.168.1.127).

+.TH CONSERVER.PASSWD 5 "@CONSERVER_DATE@" "conserver-@CONSERVER_VERSION@" "conserver"
+.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"
+(you may need to edit /etc/pam.conf or create /etc/pam.d/conserver).
+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.

+I put together the sample configuration files in this directory in hopes

+configuration file format.  Each of the files are syntatically correct,

-# $Id: INSTALL,v 4.4 94/07/19 14:48:29 ksb Exp $
-#
-# 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]

+.IR logfile ]
+.SH DESCRIPTION
+.B Conserver
+is the daemon that manages
+remote access to system consoles by multiple users via the
+.BR console (1)
+client program and (optionally) log the console output.
+It can connect to consoles via local serial ports, Unix domain sockets, TCP
+sockets (for terminal servers and the like), or any external program.
+.PP
+When started,
+.B conserver
+reads the
+.BR conserver.cf (5)
+file for details of each console.
+The console type, logging options, serial or network parameters, and user access
+levels are just a few of the things that can be specified.
+Command-line options are then applied, possibly overriding
+.BR conserver.cf (5)
+settings.
+.B Conserver
+categorizes consoles into two types: those it should actively manage, and
+those it should just know about, so it can refer clients to other
+.B conserver
+instances.
+If the
+.B master
+value of a console matches the hostname or ip address of the local machine,
+.B conserver
+will actively manage the console.
+Otherwise, it's considered a ``remote'' console and managed by a different
+server.
+.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 the
+.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
+When Unix domain sockets are used between the client and
+server (enabled using
+.BR --with-uds ),
+authentication checks are done on the hardcoded address ``127.0.0.1''.
+Automatic client redirection is also disabled (as if the
+.B \-R
+option was used) since the client cannot communicate with remote servers.
+The directory used to hold the sockets is checked to make sure it's empty
+when the server starts.
+The server will
+.B not
+remove any files in the directory itself, just in case the directory is
+accidentally specified as ``/etc'' or some other critical location.
+The server will do its best to remove all the sockets when it shuts down,
+but it could stop ungracefully (crash, ``kill -9'', etc)
+and leave files behind.
+It would then be up to the admin (or a creative startup script) to clean
+up the directory before the server will start again.
+.PP
+.B Conserver
+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.
+.PP
+The
+.B conserver
+parent process will automatically respawn any child process that dies.
+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
+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 (including any debug 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).
+.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

+.TP
+.BI \-M master
+Normally, 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.
+However, if
+.B --with-uds
+was used to enable Unix domain sockets for client/server communication,
+this points conserver to the directory where it should store the sockets.
+The default
+.I master
+directory
+.RB (`` /tmp/conserver '')
+may be changed at compile time using the
+.B --with-uds
+option.
+.TP
+.B \-n
+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).
+Without this option, or if
+.I min
+is zero, no periodic attempts occur.
+.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.
+If the
+.B --with-uds
+option was used, this option is ignored.
+.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.
+Using more than one
+.B \-S
+will cause conserver to output various information about each console in 5
+colon-separated fields, enclosed in curly-braces.
+The philosophy behind the output is to provide information to allow external
+detection of multiple consoles access the same physical port.
+Since this is
+.I highly
+environment-specific, conserver cannot do the check internally.
+.RS
+.TP 9
+.I name
+The name of the console.
+.TP
+.I master
+The hostname of the master conserver host for the console.
+.TP
+.I aliases
+The console aliases in a comma-separated list.
+.TP
+.I type
+The type of console.
+Values will be a `/' for a local device, `|' for
+a command, `!' for a remote port, `%' for a Unix domain socket,
+and `#' for a noop console.
+.TP
+.I details
+Multiple values are comma-separated and depend on the type of the console.
+Local devices will have the values of the device file and baud rate/parity.
+Commands will have string to invoke.
+Remote ports will have the values of the remote hostname and port number.
+Unix domain sockets will have the path to the socket.
+Noop consoles will have nothing.
+.RE
+.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 utilities 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 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 its 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 its 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.  See the
+.B \s-1PROTOCOL\s0
+file in the distribution for further details.
+.SH FILES

+The following default file locations may be overridden
+at compile time or by the command-line options described above.

+.B conserver \-V

-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.

-.TH CONSOLE 8 "Local"
-.SH NAME
-console \- console server client program
-.SH SYNOPSIS
-\fBconsole\fP [\-\fBaAfFsS\fP] [\-\fBrv\fP] [\-\fBe\fP \fIesc\fP] [\-\fBM\fP \fIserver\fP] \fIhost\fP
-.br
-\fBconsole\fP [\-\fBv\fP] [\-\fBhdDuVwx\fP] [\-\fBb\fP \fImessage\fP]
-.br
-\fBconsole\fP [\-\fBqQ\fP] [\-\fBM\fP \fIserver\fP]
-.SH DESCRIPTION
-.B Console
-is used to manipulate console terminals remotely or poll running
-\fIconserver\fP(8L) daemons for status information.
-.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
-.B console
-outputs only the requested information.
-.SH OPTIONS
-.TP
-.B \-a
-Access a console with a two-way connection (this is the default).
-.TP
-.BI \-b message
-Broadcast a \fImessage\fP to all users connected to the console server.
-.TP
-.B \-d
-Display daemon versions.  The \fIconsole\fP client connects to each
-server to request its version information.  The uppercase varient of
-this option only requests the primary server's version.
-.TP
-.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''.
-.TP
-.B \-f
-Same as
-.I \-a
-except it will force any existing connection into spy mode.
-.TP
-.B \-h
-Display a brief help message.
-.TP
-.BI \-M server
-The \fIconsole\fP client program polls \fIserver\fP as the primary server,
-rather than the hard coded default (``console'').
-.TP
-.B \-q
-The \fIconsole\fP client requests the server daemon quit (shutdown).
-A password is sent in the protocol stream, if none is required for
-the local host to shutdown the server just press return.
-.TP
-.B \-Q
-Like -q, but just acts on the primary server.
-.TP
-.B \-r
-Request a raw connection to the group control virtual console,
-this is only useful for learning the protocol used by the
-interactive sequence.
-.TP
-.B \-s
-Requests a read-only (spy mode) connection.
-If this mode all the escape sequences (below) work, or report errors,
-but all other keyboard input is discarded.
-.TP
-.B \-u
-Show a list of all consoles with status and attached users.
-.TP
-.B \-V
-Output the version of the console client program.
-.TP
-.B \-v
-Be more verbose during when building the connection(s).
-Use this option in combination with any of `show' options (below)
-for added benefit.
-.TP
-.B \-w
-Show a list of all connections to consoles.
-.TP
-.B \-x
-Show a list of consoles and devices.
-.PP
-The \-\fBA\fP, \-\fBF\fP, or \-\fBS\fP options have the same effect as
-their lower case variants.
-In addition they each request the last 20 lines of the console output after
-making the connection.
-.PP
-Any default (\-\fBa\fP) connection is dropped to spy mode if
-someone else is attached read-write.
-.SH "ESCAPE SEQUENCES"
-The connection can be controlled by a two character escape sequence, followed
-by a command.  The default escape sequence is ``control-E c''
-(octal 005 143).  Commands are:
-.sp
-.TS
-c l.
-a	switch to attach mode
-c	toggle flow control (don't do this)
-d	down the current console
-e	change the escape sequence to the next two characters
-f	force a switch to attach mode
-g	group info
-L	toggle logging on/off
-l1	send a 3-second serial line break (might halt a Sun)
-	("ell" then "one", not the L1 key)
-o	reopen the line to clear errors (silo overflows)
-p	replay the last 60 lines of output
-r	replay the last 20 lines of output
-s	switch to spy mode
-u	show other users on this port
-v	show the version of the group server
-w	who is using this console
-x	examine this group's devices and modes.
-z	suspend this connection
-?	display list of commands
-^I	toggle tab expansion
-^J	continue, ignore the escape sequence
-^R	replay the last line only
-\.	disconnect
-.TE
-.sp
-.PP
-If any other character is hit after the escape sequence, all three characters
-will be discarded.
-Note that a line break or a down command
-can only be sent from a full two-way attachment.
-To send the escape sequence through the connection one must redefine
-the outer escape sequence.
-.PP
-In the \-u output, the login \fB<none>\fP indicates no one is
-viewing that console, the login \fB<spies>\fP indicates that
-no one has a full two-way attachment.  When no one is attached to
-a console its output is cloned to the stdout of the server process.
-.SH EXAMPLES
-.TP
-console \-u
-Outputs something like:
-.sp
-.RS
-.TS
-l18 l l.
-dumb	up	<none>
-expert	up	ksb@mentor
-tyro	up	<spies>
-mentor	up	<none>
-sage	up	fine@cis
-.TE
-.RE
-.sp
-The \fB<none>\fP indicates no one is viewing \fIdumb\fP or \fImentor\fP,
-the \fB<spies>\fP indicates only read-only connections exist for \fItyro\fP,
-other \fIlogin\fP@\fIhost\fP entries are the currently attached
-\fIsage\fP and \fIexpert\fP.
-.TP
-console \-w
-Outputs something like:
-.sp
-.RS
-.TS
-l18 l l.
-ksb@extra	attach 2days	expert
-file@cis	attach 21:46	sage
-dmr@alice	spy     0:04	tyro
-.TE
-.RE
-.sp
-The third column is the idle time of the user.  Either hours:minutes or number
-of days is displayed.
-.TP
-console \-e \*(lq^[1\*(rq lv426
-Requests a connection to the host ``lv426'' with the escape characters
-set to ``escape one''.
-.SH BUGS
-Connections suspended under Dynix sometimes break the kernel when
-resumed.  Suspended connections are a poor idea in general, just
-disconnect instead.
-.PP
-It is possible to create a loop of console connections, with ugly results.
-Never run \fIconsole\fP from within a console connection.
-.PP
-The \-\fBr\fP option doesn't help to explain how connections get built.

+    This version of "chat" is derived from the NetBSD variant found in
+    /usr/src/usr.sbin/pppd/chat.

+.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.

+    Subject: Red Hat conserver init script for Linux
+
+    Below my sig I've pasted an init script that will start and stop
+    conserver on Red Hat Linux. It's set up to work with the chkconfig
+    runlevel manager that ships with Red Hat.

+
+    If this spec file goes in the root directory of the distribution as
+    conserver.spec, then Red Hat users will be able to build rpms by doing no
+    more than
+
+    % rpm -ta conserver-7.x.x.tar.gz
+
+    I'll be happy to do any tweaking necessary to get this to work.
