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] [--mlock] [--strict]

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.

       --strict
               Strict configuration check (don't start with config errors)

       -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.

       --mlock
               (Unix only) Lock GnuGk into memory to prevent it being swaped out.

   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.
