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.

       rarp - manipulate the system RARP table

       This  program  is  obsolete.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

-V     Display the version of RARP in use.

       -v     Tell the user what is going on by being verbose.

       -ttype
              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
              IEEE802.310MbpsEthernet.  Other values might include network technologies such as AX.25(ax25)
              and NET/ROM(netrom).-a--list Lists the entries in the RARP table.

       -dhostname--deletehostname
              Remove all RARP entries for the specified host.

       -shostnamehw_addr--sethostnamehw_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.

       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.
