       rarp - manipulate the system RARP table

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

       This program is obsolete.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

       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.

       -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


       --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

       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.
