Using Configuration Utilities
3-20 Part No. 6B4389 June 1999
Using rarp to Configure the IP Address
You can configure the NIC IP address using the reverse ARP
(rarp) utility on the host computer. To use rarp, edit the /etc/ethers
file with an entry similar to the following. If the file does not exist,
you can create it.
00:40:17:00:01:07 KOD_000107
The first entry is the Ethernet address of the NIC print server, and
the second entry is the name of the NIC.
NOTE: The name must be the same as the one you entered in the
/etc/hosts file.
If the rarp daemon is not already running, start it by using one of
the following commands:
• rarpd
• rarpd -a in.rarpd -a
NOTE: Refer to the system’s documentation for more information
about starting the rarp daemon.
To verify that the rarp daemon is running on a Berkeley Unix
system, type the following command:
ps -ax I grep -v grep I grep rarpd
For At&T UNIX systems, type the following command:
ps -ef I grep -v grep I grep rarpd
The NIC will get the IP address from the rarp daemon when it is
powered on.
Using BOOTP to Configure the IP Address
BOOTP is an alternative to rarp that allows configuration of the
subnet mask and gateway. To use BOOTP to configure the IP
address into the NIC, make sure that BOOTP is installed and
running on your host computer. It should appear in the /etc/
services file on your host as a real service.
BOOTP is usually started from the /etc/inetd.conf file. To enable it,
remove the # in front of the bootp entry in that file. For example, a
typical bootp entry in the /etc/inetd. Conf file would be:
#bootp dgram udp wait /usr/etc/bootpd bootpd -1
