NAME
     rarpd -- reverse ARP daemon

SYNOPSIS
     rarpd [-adflt] if0	[... ifN]

DESCRIPTION
     rarpd services Reverse ARP	requests on the	Ethernet connected to the
     specified interfaces.  Upon receiving a request, rarpd maps the target
     hardware address to an IP address via its name, which must	be present in
     both the ethers(5)	and hosts(5) databases.	 If a host does	not exist in
     both databases, the translation cannot proceed and	a reply	will not be
     sent.

     In	normal operation, rarpd	forks a	copy of	itself and runs	in the back-
     ground.  Anomalies	and errors are reported	via syslog(3).

     The options are as	follows:

     -a	     Listen on all the Ethernets attached to the system.  If -a	is
	     omitted, a	list of	interfaces must	be specified.

     -d	     Run in debug mode,	with all the output to stderr.	This option
	     implies the -f option.

     -f	     Run in the	foreground.

     -l	     Log all requests to syslog(3).

     -t	     Only honour a request if the server (the host that	rarpd is run-
	     ning on) can "boot" the target; that is, if a file	or directory
	     called /tftpboot/ipaddr exists, where ipaddr is the target	IP ad-
	     dress expressed in	uppercase hexadecimal (only the	first 8	char-
	     acters of filenames are checked).

FILES
     /etc/ethers  Ethernet host	name database.
     /etc/hosts	  Host name database.
