RARP(8) Linux System Administrator'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This program is obsolete.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.de-
mentia.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 de-
fault value of this parameter is ether (i.e. hardware code 0x01
for IEEE 802.3 10Mbps Ethernet . Other values might include net-
work technologies 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 hard-
ware address set to hw_addr. The format of the hardware address
is dependent on the hardware 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.
