NOTE: If you choose to re-enable a DHCP configuration, the print server will acquire its
configuration information from a DHCP server. This means that when you choose DHCP and
complete your configuration session (using Telnet, for example), the TCP/IP protocol for the print
server is re-initialized and all current configuration information is deleted. The print server then
attempts to acquire new configuration information by sending DHCP requests on the network to
a DHCP server.
For DHCP configuration through Telnet, refer to “Using Telnet (IPv4) on page 41” in this chapter.
Using RARP (IPv4)
This section describes how to configure the print server using the Reverse Address Resolution Protocol
(RARP) on UNIX and Linux systems.
This setup procedure enables the RARP daemon running on your system to respond to a RARP request
from the HP Jetdirect print server and to supply the IP address to the print server.
1. Turn the printer off.
2. Log onto your UNIX or Linux system as a superuser.
3. Make sure the RARP daemon is running on your system by typing the following command at the
system prompt:
ps -ef | grep rarpd (Unix)
ps ax | grep rarpd (BSD or Linux)
4. The system response should be similar to the following:
861 0.00.2 24 72 5 14:03 0:00 rarpd -a
860 0.00.5 36 140 5 14:03 0:00 rarpd -a
5. If the system does not display a process number for the RARP daemon, see the rarpd man page
for instructions on starting the RARP daemon.
6. Edit the /etc/hosts file to add your designated IP address and node name for the HP Jetdirect
print server. For example:
192.168.45.39 laserjet1
7. Edit the /etc/ethers file (/etc/rarpd.conf file in HP-UX 10.20) to add the LAN hardware
address/station address (from the configuration page) and the node name for the HP Jetdirect print
server. For example:
00:01:E6:a8:b0:00 laserjet1
NOTE: If your system uses Network Information Service (NIS), you need to incorporate
changes to the NIS host and ethers databases.
8. Turn the printer on.
9. To verify that the card is configured with the correct IP address, use the ping utility. At the prompt,
type:
ping <IP address>
