NAME
       conman - ConMan client


SYNOPSIS
       conman [OPTION]... [CONSOLE]...


DESCRIPTION
       conman  is  a  program  for connecting to remote consoles being managed by conmand.
       Console names can be separated by  spaces  and/or  commas.   Globbing  is  used  by
       default  to  match  console names against the configuration, but regular expression
       matching can be enabled with the '-r' option.

       conman supports three modes of console  access:  monitor  (read-only),  interactive
       (read-write),  and  broadcast (write-only).  If neither the '-m' (monitor) nor '-b'
       (broadcast) options are specified, the console session  is  opened  in  interactive
       mode.


OPTIONS
       -b     Broadcast  to  multiple consoles (write-only).  Data sent by the client will
              be copied to all specified consoles in parallel, but console output will not
              be  sent  back  to  the client.  This option can be used in conjunction with
              '-f' or '-j'.

       -d destination
              Specify  the  location  of  the  conmand  daemon,  overriding  the   default
              [127.0.0.1:7890].   This  location may contain a hostname or IP address, and
              be optionally followed by a colon and port number.

       -e character
              Specify the client escape character, overriding the default [&].

       -f     Specify that write-access to the console should be "forced", thereby  steal-
              ing  the  console  away  from existing clients having write privileges.  The
              original clients are informed by conmand of who  perpetrated  the  theft  as
              their connections are terminated.

       -F file
              Read  console names/patterns from file.  Only one console name may be speci-
              fied per line.  Leading and trailing whitespace, blank lines,  and  comments
              (ie, lines beginning with a '#') are ignored.

       -h     Display a summary of the command-line options.

       -j     Specify that write-access to the console should be "joined", thereby sharing
              the console with existing clients having  write  privileges.   The  original
              clients  are  informed  by  conmand that a new client has been granted write
              privileges.

       -l file
              Log console session output to file.

       -L     Display license information.

       -m     Monitor a console (read-only).

       -q     Query conmand for consoles matching the  specified  names/patterns.   Output
              from this query can be saved to file for use with the '-F' option.

       -Q     Enable  quiet-mode,  suppressing  informational  messages.  This mode can be
              toggled within a console session via the '&Q' escape.

       -r     Match console names via regular expressions instead of globbing.

       -v     Enable verbose mode.

       -V     Display version information.


ESCAPE CHARACTERS
       The following escapes are supported and assume the default escape character [&]:

       &?     Display a list of currently available escapes.

       &.     Terminate the connection.

       &&     Send a single escape character.

       &B     Send a "serial-break" to the remote console.

       &F     Switch from read-only to read-write via a "force".

       &I     Display information about the connection.

       &J     Switch from read-only to read-write via a "join".

       &L     Replay up the the last 4KB of console output.  This escape requires the con-
              sole device to have logging enabled in the conmand configuration.

       &M     Switch from read-write to read-only.

       &Q     Toggle quiet-mode to display/suppress informational messages.

       &R     Reset  the  node  associated  with  this  console.   This  escape requires a
              "resetcmd" to be specified in the conmand configuration.

       &Z     Suspend the client.


ENVIRONMENT
       The following environment variables override the default settings.

       CONMAN_HOST
              Specifies the hostname or IP address at which to contact conmand, but may be
              overridden  by  the  '-d' command-line option.  A port number separated by a
              colon may follow the hostname  (ie,  host:port),  although  the  CONMAN_PORT
              environment  variable  takes  precedence.   If  not  set,  the  default host
              [127.0.0.1] will be used.

       CONMAN_PORT
              Specifies the port on which to contact conmand, but may be overridden by the
              '-d' command-line option.  If not set, the default port [7890] will be used.

       CONMAN_ESCAPE
              The first character of this variable specifies the escape character, but may
              be  overridden  by  the  '-e'  command-line option.  If not set, the default
              escape character [&] will be used.


SECURITY
       The client/server communications are not yet encrypted.
