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       This  program  is  obsolete.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 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.  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.
