NAME

     gnugk — The GNU Gatekeeper

SYNOPSIS

     gnugk [-hdrt] [-c filename] [-s section] [-l n] [-b n] [-u name] [-d name] [-rr]
           [-o filename] [--pid filename] [--core n]

DESCRIPTION

     The GNU Gatekeeper is an open-source project that implements a H.323 gatekeeper.  A H.323
     gatekeeper controls all H.323 clients in its zone.  It allows you, among other things, to
     register devices, make calls, perform AAA (Authentication, Authorization and Auditing),
     manage configurations at runtime and traverse NAT.

OPTIONS

     The behavior of the gatekeeper is determined through command line options and the
     configuration file.  Some command line options may override settings found in the
     configuration file.  For example, the option -l overrides the setting “TimeToLive” in the
     configuration file.  Almost every option has a short and a long format, e.g., -c is the same
     as --config.

     -h --help
             Show all available options and quit the program.

     -c --config filename
             Specify the configuration file to use.

     -s --section section
             Specify which main section to use in the configuration file.  The default is
             [Gatekeeper::Main].

     -l --timetolive n
             Specify the time-to-live timer (in seconds) for endpoint registration.  This
             overrides the setting “TimeToLive” in the configuration file.  A detailed
             explanation can be found in the manual.

     -b --bandwidth n
             Specify the total bandwidth available for the gatekeeper.  Without specifying this
             option, bandwidth management is disabled by default.

     --pid filename
             Specify the pid file.  Only valid for Unix version.

     -u --user name
             Run the gatekeeper process as this user.  Only valid for Unix versions.

     --core n
             (Unix only) Enable writing core dump files when the application crashes.  A core
             dump file will not exceed n bytes in size.  A special constant “unlimited” may also
             be specified.

   Gatekeeper Mode
     The options in this subsection override the settings in the [RoutedMode] section of the
     configuration file.

     -d --direct
             Use direct endpoint call signaling.

     -r --routed
             Use gatekeeper routed call signaling.

     -rr --h245routed
             Use gatekeeper routed call signaling and H.245 control channel.

   Debug Information
     -o --output filename
             Write trace log to the specified file.

     -t --trace
             Set trace verbosity.  The more -t you add, the more verbose to output.  For example,
             use -ttttt to set the trace level to 5.
