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.
-V Display the version of RARP in use.
-v Tell the user what is going on by being verbose.
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.
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.
