TCP/IP Configuration

5.2.2 Using rarp
The Reverse Address Resolution Protocol (rarp) allows network devices to query a server
for their IP addresses on startup. To store the IP address, use the following procedure:
1. Turn off the DEClaser 5100 printer.
2. Log in as superuser on the rarpd server. However, if the server resides on another
subnet, complete this procedure to store the IP address in the NIC, reconnect the NIC
anywhere on the network, and then use the nsconfig utility to change the IP address.
See Section 5.5 for instructions on using nsconfig.
3. Find the Ethernet address of the network interface card. The address is printed on the
configuration status report when you power on the printer.
4. Edit the hosts file (usually /etc/hosts) or use NIS or DIS to add the IP Address and
network interface card's node name. See the network administrator for the IP address.
For example, a NIC 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:
00:40:c8:00:00:ff printfast
6. If the rarp daemon is running, stop it and restart it. Verify that the daemon is running.
7. Check the printer to see that the NIC is connected to the network. Turn on the printer.
8. Wait until the printer powers up and finishes initializing to allow enough time for the
IP address to become known and to be saved in non-volatile memory. After the
printer has powered up fully, turn the printer off.
9. Turn the printer back on again and send a ping command to verify that the NIC
obtained its IP address. For example:
ping 192.9.200.200
10. If the NIC has the address, the result is a confirmation message:
192.9.200.200 is alive
11. Remove, or comment out, your changes to the /etc/ethers file.
12. Stop the rarp daemon and, if you want it to run, restart it.
