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       This program is obsolete.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 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.
