RARP(8)

NAME
       rarp - manipulate the system RARP table

SYNOPSIS
       rarp [-v] [-t type] -a [hostname]
       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
       arp program also allows a complete dump of the RARP table.

OPTIONS
       -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 [hostname]
              Shows  the  entries of the specified hosts.  If the
              hostname parameter is not used, all entries will be
              displayed.

       -d hostname
              Remove  the  entrie(s) of the specified host.  This
              can be used if the indicated host is brought  down,
              for example.

       -s hostname hw_addr
              Create an 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 Sun's) 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.
