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       This program is obsolete.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.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 de-
              fault value of this parameter is ether (i.e. hardware code  0x01
              for  IEEE  802.3  10Mbps  Ethernet .  Other values might include
              network 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 Ether-
              net 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.
