NAME
  gated - gateway routing daemon

SYNOPSIS
  /usr/sbin/gated [-c] [-C] [-n] [-N] [-t trace_options] [-f config_file]
  [trace_file]

OPTIONS
  -c  Specifies that gated parse the configuration file for syntax, then
      exit. If there are no errors, gated leaves a dump file in
      /usr/tmp/gated_dump.

      You do not need root privileges to use the -c option.  However, if you
      do not have root privileges, gated might not be able to read the kernel
      forwarding table and interface configuration. The -c option implies -
      tgeneral.	 All trace_option clauses in the configuration file are
      ignored.

  -C  Specifies that gated parse the configuration file for syntax errors.
      If no errors occur, gated exits with a status 0.	Otherwise, it exits
      with a status 1.

      You do not need root privileges to use the -C option.  However, if you
      do not have root privileges, gated might not be able to read the kernel
      forwarding table and interface configuration.

  -n  Specifies that gated not modify the kernel forwarding table.  This is
      used for testing gated configurations with actual routing data.

  -N  Specifies that gated run as a user process.  Normally, if tracing to
      stderr is not specified and if the parent process is not init, gated
      runs as a daemon process.	 This allows the use of an /etc/inittab-like
      method of invoking gated.

  -t  trace_options
      Specifies a comma-separated list of trace options to be enabled on
      startup.	If no options are specified, general is assumed.  No space is
      allowed between this option and its arguments.

      Use this to trace events that take place before the configuration file
      is parsed, such as determining the interface configuration and reading
      routes from the kernel.

      See gated.conf(4) for valid trace options and a more detailed
      explanation of tracing.

  -f  config_file
      Specifies an alternate configuration file. By default, gated uses
      /etc/gated.conf.

      If a trace file is specified on the command line, or no trace options
      are specified on the command line, gated detaches from the terminal and
      runs in the background.  If trace options are specified without
      specifying a trace file, gated assumes that tracing is desired to
      stderr and remains in the foreground.

DESCRIPTION
  The gated routing daemon is based on Release 4.0.6 from NextHop
  Technologies, Inc.  The gated daemon replaces routed and egpup, and
  currently handles the RIP, BGP, EGP, HELLO, and OSPF routing protocols.
  The gated process can be configured to perform all routing protocols or any
  subset of them.

  SIGNAL PROCESSING

  You can use the following signals to control gated:

  SIGHUP
      Causes gated to reread the configuration file.  The gated daemon first
      performs a clean-up of all allocated policy structures. All BGP and EGP
      peers are flagged for deletion and the configuration file is reparsed.

      If the reparse is successful, any BGP and EGP peers that are no longer
      in the configuration are shut down, and new peers are started.  Gated
      attempts to determine if changes to existing peers require a shutdown
      and restart. OSPF is not capable of reconfiguring, it is shutdown and
      restarted during a reconfiguration. This may have an adverse impact on
      the routing system.

      It should also be possible to enable/disable any protocol without
      restarting gated.

  SIGINT
      Causes gated to write the current state of all tasks, timers,
      protocols, and tables to the /usr/tmp/gated_dump file.

      On systems supporting fork(), this is done by forking a subprocess to
      dump the table information.  This does not affect gated's routing
      functions.  On systems where memory management does not support copy-
      on-write, fork() causes the gated address space to be duplicated; this
      might cause a noticeable impact on the system.  On systems not
      supporting fork(), the main process immediately processes the dump,
      which might impact gated's routing functions.

  SIGTERM
      Causes gated to shut down.  All tasks and protocols are asked to
      shutdown. Most terminate immediately, except EGP peers, which waits for
      confirmation.  You might have to send SIGTERM once or twice if it this
      process takes too long to shut down.

      All protocol routes are removed from the kernel forwarding table on
      receipt of a SIGTERM. Interface routes, routes with RTF_STATIC set
      (from the route command where supported) and static routes specifying
      retain will remain. To terminate gated with the exterior routes intact,
      use SIGKILL.

  SIGUSR1
      Causes gated to close the trace file.  A subsequent SIGUSR1 reopens the
      trace file.  This allows the file to be moved regularly.

      You cannot use SIGUSR1 if a trace file has not been specified or if
      tracing is being performed to stderr.

  SIGUSR2
      Causes gated to rescan the kernel interface list for changes.

FILES
  /usr/tmp/gated_dump
      Contains gated status information.

  /etc/gated.conf
      Contains the gated configuration information.

  /var/run/gated.pid
      Contains the gated process id (PID).
