RARP(8)            Linux System Administrator's Manual           RARP(8)

NAME         top

       rarp - manipulate the system RARP table

SYNOPSIS         top

       rarp [-V] [--version] [-h] [--help]
       rarp -a
       rarp [-v] -d hostname ...
       rarp [-v] [-t type] -s hostname hw_addr

NOTE         top

       This program is obsolete.  From version 2.3, the Linux kernel no
       longer contains RARP support.  For a replacement RARP daemon, see

DESCRIPTION         top

       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         top

       -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).


       --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         top

       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.
