 NAME
      rarpc - Reverse Address Resolution Protocol client

 SYNOPSIS
      rarpc [-d] [-e|-s] [-n count] interface_name

 DESCRIPTION
      rarpc, the Reverse Address Resolution Protocol client, implements the
      client portion of the Reverse Address Resolution Protocol (see SEE
      ALSO).  It sends RARP requests for the specified interface's hardware
      address and waits for the response from the RARP server.	rarpc can be
      used during boot-time initialization to find the IP address of an
      interface.  To do so, set the IP_ADDRESS[i] variable of interface i
      with IP_ADDRESS[i]=RARP in /etc/rc.config.d/netconf.

      Options are:

	   -d		    Print debugging information.

	   -e		    Use ethernet encapsulation only.

	   -s		    Use SNAP encapsulation only.

	   -n count	    Transmits count requests and waits for each one
			    to time out before giving up.

	   interface_name   Identifies the interface to request information
			    about.

      If a response is received, it prints the IP address to its standard
      output.  This information can be used to configure the interface as
      seen in /sbin/init.d/net.

      If a response is not received, the client will retransmit after 2
      seconds, and then after 4 seconds.  After that, retransmissions occur
      every 8 seconds.

 RETURN VALUE
      Exit status is 1 if the command fails or no RARP response is received.
      Exit status is 0 and the IP address is printed to standard output if a
      response is received.

 LIMITATIONS
      1. The rarpc client cannot be run at the same time a rarpd daemon is
	 running on the same interface.

      2. The rarpc client supports only ethernet, 100VG and FDDI network
	 interfaces.
