 rarpd(1M)                                                         rarpd(1M)

 NAME    [Toc]    [Back]
      rarpd - Reverse Address Resolution Protocol daemon

 SYNOPSIS    [Toc]    [Back]
      rarpd [-d] [-f config_file] [interface_name]

 DESCRIPTION    [Toc]    [Back]
      rarpd, the Reverse Address Resolution Protocol daemon, implements the
      server portion of the Reverse Address Resolution Protocol [1].  It
      responds to RARP requests providing the requested client IP address.
      Rarpd can be started during boot-time initialization.  To do so, set
      the RARPD variable with RARPD=1 in /etc/rc.config.d/netconf.

      Options are:

           -d             Print debugging information.

           -f config_file Use the specified config_file database instead of

           interface_name Respond to requests over just this interface.

      The configuration file database contains hardware address to IP
      address mappings.  Other than comment lines (which begin with a '#')
      and blank lines, all lines are considered client entries.  A client
      entry is of the form:

           hardware_address WHITE_SPACE ip_address

      where hardware_address consists of (:) colon-separated hexadecimal
      bytes, and ip_address consists of (.) dot-seperated decimal bytes.
      For example:

           # hardware addr   IP addr
           #   ethernet clients
           #   100VG clients
           #   FDDI clients

      There must be exactly 6 hardware address bytes.  There must be exactly
      4 protocol address bytes.

      The following signals have the specified effect when sent to the rarpd
      process using the kill(1) command:

           SIGHUP    Causes server to read the config file and reload

           SIGINT    Dumps current data base and cache to /var/tmp/rarpd.db.

 RETURN VALUE    [Toc]    [Back]
      Exit status is 1 if the command fails, and error messages are written
      to stderr and/or syslog.  Typically, the daemon will continue
      answering requests until externally interrupted.

 LIMITATIONS    [Toc]    [Back]
      1. The rarpd daemon supports only ethernet, 100VG and FDDI network

      2. The rarpd daemon supports only 4 byte Internet Protocol addresses.

      3. The rarpd and rarpc programs cannot be run on the same interface at
         the same time.

 AUTHOR    [Toc]    [Back]
      rarpd was developed by HP.
