UNIX Configuration 7-5
7.2.2 Using rarp
The Reverse Address Resolution Protocol (rarp) allows network devices to query a
server for their IP addresses on start-up. For this procedure, there needs to be a
workstation with a rarp server. To store the IP address, use the following procedure:
1. Turn off the printer.
2. Log in as superuser on the rarp server. However, if the server resides on another
subnet, complete this procedure to store the IP address in the print server. Recon-
nect the print server anywhere on the network, and then use the Telnet or the
HTML pages accessed by MAP or a Web Browser to adjust the IP parameters for
the subnet on which the EcoLAN 3000E is to operate.
3. Find the Ethernet address of the EcoLAN 3000E. The address is listed as Hard-
ware Address on the EcoLAN 3000E Network Status Page.
4. Edit the hosts file (usually /etc/hosts) or use NIS or DIS to add the IP Address and
EcoLAN 3000E’s node name. See the network administrator for the IP address.
For example, a print server with the name of printfast has the following entry:
192.9.200.200 printfast
5. Edit the /etc/ethers file or use NIS or DIS to add the Ethernet address. To continue
the example, for the printfast card with an Ethernet address of 00:40:c8:00:00:ff,
make the following entry:
0:40:c8:0:0:ff printfast
6. If the rarp daemon is running, stop it and restart it. Verify that the daemon is run-
ning.
7. Check the printer to see that the print server is connected to the network. Turn on
the printer.
8. Wait 1 or 2 minutes to allow enough time for the IP address to become known and
to be saved in non-volatile memory. Press the Status key and verify the new IP
address information on the EcoLAN 3000E Network Status page or send a ping
command to verify that the 3000E obtained its IP address. For example:
ping 192.9.200.200
If the 3000E has the address, the result is a confirmation message:
192.9.200.200 is alive
9. Remove, or comment out, your changes to the /etc/ethers file.
10. Stop the rarp daemon and, if you want it to run, restart it.
