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       This  program  is  obsolete.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 sup‐
       port.  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 pro‐
       gram 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  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 hardware 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 Eth‐
              ernet 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 pro‐
       vide  other  remote  boot  services. Therefore never gratuitously add rarp entries unless you
       wish to meet the wrath of the network administrator.
