RARP(8) 						     Linux Programmer's Manual							   RARP(8)

NAME

       rarp - manipulate the system RARP table

SYNOPSIS

       rarp [-V] [--version] [-h] [--help]
       rarp -a
       rarp [-v] -d hostname ...
       rarp [-v] [-t type] -s hostname hw_addr

NOTE

       This  program  is  obsolete.   From  version  2.3,  the	Linux  kernel no longer contains RARP support.	For a replacement RARP daemon, see
       ftp://ftp.dementia.org/pub/net-tools

DESCRIPTION

       Rarp manipulates the kernel's RARP table in various ways.  The primary options are clearing an address mapping entry and  manually  setting
       up one.	For debugging purposes, the rarp program also allows a complete dump of the RARP table.

OPTIONS

       -V     Display the version of RARP in use.

       -v     Tell the user what is going on by being verbose.

       -t type
	      When  setting or reading the RARP table, this optional parameter tells rarp which class of entries it should check for.  The default
	      value of this parameter is ether (i.e. hardware code 0x01 for IEEE 802.3 10Mbps Ethernet .  Other values might include network tech-
	      nologies such as AX.25 (ax25) and NET/ROM (netrom).

       -a

       --list Lists the entries in the RARP table.

       -d hostname

       --delete hostname
	      Remove all RARP entries for the specified host.

       -s hostname hw_addr

       --set hostname hw_addr
	      Create  a  RARP  address	mapping  entry	for host hostname with hardware address set to hw_addr class, but for most classes one can
	      assume that the usual presentation can be used.  For the Ethernet class, this is 6 bytes in hexadecimal, separated by colons.

WARNING

       Some systems (notably older Suns) assume that the host replying to a RARP query can also provide  other	remote	boot  services.  Therefore
       never gratuitously add rarp entries unless you wish to meet the wrath of the network administrator.
