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       This program is obsolete.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
              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.
