Using Rarp (Ipv4) - HP Jetdirect J7974E Administrator's Manual

If you do not want your HP Jetdirect print server configured through DHCP, you must re-configure the
print server to use a different configuration method.
1. (For IPv4 configuration) If you use the printer control panel to set Manual or BOOTP configuration,
then DHCP will not be used.
2. You can use Telnet to set Manual (status indicates "User Specified") or BOOTP configuration, then
DHCP will not be used.
3. You can manually modify the TCP/IP parameters through a supported Web browser using the
Jetdirect embedded Web server or HP Web Jetadmin.
If you change to BOOTP configuration, the DHCP-configured parameters are released and the TCP/IP
protocol is initialized.
If you change to Manual configuration, the DHCP-configured IP address is released and the user-
specified IP parameters are used. Therefore, if you manually provide the IPv4 address, you should
also manually set all of the configuration parameters, such as subnet mask, default gateway,
and idle timeout.
NOTE
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 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.
