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       This  program  is  obsolete.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.
