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 speci- fied 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, over- riding both the default port  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 speci- fied configuration, thereby re-opening both that daemons 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 daemons log file and individual console log files at start-up.
SIGNALS SIGHUP Close and re-open both the daemons log file and the indi- vidual console log files. Conversion specifiers within filenames will be re-evaluated. This is useful for logro- tate 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 spec- ifying "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., con- man.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.
