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

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 host-
              name with hardware address set  to  hw_addr  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.
