rarp(8)


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   This program is obsolete.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.
