CONMAND(8)                ConMan: The Console Manager               CONMAND(8)



NAME
       conmand - ConMan daemon


SYNOPSIS
       conmand [OPTION]...


DESCRIPTION
       conmand  is the daemon responsible for managing consoles defined by its configuration file as well as listening
       for connections from clients.


OPTIONS
       -c file
              Specify a configuration file, overriding the default location [/etc/conman.conf].

       -F     Run the daemon in the foreground.

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

       -k     Send a SIGTERM to the conmand process associated with the specified configuration, thereby  killing  the
              daemon.  Returns 0 if the daemon was successfully signaled; otherwise, returns 1.

       -L     Display license information.

       -p port
              Specify  the  port on which conmand will listen for clients, overriding both the default port [7890] and
              the port specified in the configuration file.

       -q     Displays the PID of the conmand process associated  with  the  specified  configuration  if  it  appears
              active.  Returns 0 if the configuration appears active; otherwise, returns 1.

       -r     Send  a  SIGHUP  to  the conmand process associated with the specified configuration, thereby re-opening
              both that daemon's log file and individual console log files.  Returns 0 if the daemon was  successfully
              signaled; otherwise, returns 1.

       -v     Enable verbose mode.

       -V     Display version information.

       -z     Truncate both the daemon's log file and individual console log files at start-up.


SIGNALS
       SIGHUP      Close  and  re-open  both  the  daemon's log file and the individual console log files.  Conversion
                   specifiers within filenames will be re-evaluated.  This is useful for logrotate configurations.

       SIGTERM     Terminate the daemon.


SECURITY
       Connections to the server are  not  authenticated,  and  communications  between  client  and  server  are  not
       encrypted.  When time allows, this will be addressed in a future release.  Until then, the recommendation is to
       bind the server's listen socket to the loopback address (by specifying "server loopback=on" in conman.conf) and
       restrict access to the server host.


NOTES
       Log  messages are sent to standard-error until after the configuration file has been read, at which time future
       messages are discarded unless either the logfile or syslog keyword has been specified (cf., conman.conf(5)).

       If the configuration file is modified while the daemon is running and a pidfile was not  originally  specified,
       the  '-k'  and  '-r' options may be unable to identify the daemon process; consequently, the appropriate signal
       may need to be sent to the daemon manually.

       The number of consoles that can be simultaneously managed is limited by the maximum number of file  descriptors
       a  process  can  have  open.   The  daemon  sets its "nofile" soft limit to the maximum/hard limit.  If you are
       encountering "too many open files" errors, you may need to increase the "nofile" hard limit.
