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.
files

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This program is obsolete.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
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.
