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This program is obsolete.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.
