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This program is obsolete.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.
