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       This  program  is  obsolete.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.
