NAME
rarp - manipulate the system RARP table
SYNOPSIS
rarp [-v] [-t type] -a [hostname]
rarp [-v] -d hostname ...
rarp [-v] [-t type] -s hostname hw_addr
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
arp program also allows a complete dump of the RARP table.
OPTIONS
-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 AX.25 (ax25)
-a [hostname]
Shows the entries of the specified hosts. If the
hostname parameter is not used, all entries will be
displayed.
-d hostname
Remove the entrie(s) of the specified host. This
can be used if the indicated host is brought down,
for example.
-s hostname hw_addr
Create an RARP address mapping entry for host host-
name with hardware address set to hw_addr 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 Sun's) 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.
