Use The Arp And Ping Commands (Ipv4) - HP Jetdirect 640n Administrator's Manual

The procedure enables the RARP daemon running on your system to respond to an RARP request
from the HP Jetdirect print server and to supply the IP address to the print server. Configure RARP
using the following steps:
1. Turn the printer off.
2. Log onto your UNIX or Linux system as the super user.
3. Use the process status command to verify the RARP daemon is running on your system, as in
the following example from 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 RARP daemon is not running on the system (the process is not in the process list), see the
rarpd man page for instructions about starting the daemon.
6. Edit the /etc/hosts file to add your designated IP address and node name for the
HP Jetdirect print server, as in the following 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, as in the following example:
00:01:E6:a8:b0:00 laserjet1
NOTE:
changes to the NIS host and ethers databases.
8. Turn the printer on.
9. Verify that the card is configured with the correct IP address, by using the ping utility as in the
following example:
ping <IP address>
In the example, <IP address> is the assigned address from RARP.
10. If ping does not respond, see

Use the arp and ping commands (IPv4)

You can configure an HP Jetdirect print server with an IP address using the arp command from a
supported system. The workstation from which the configuration is made must be located on the
same network segment as the HP Jetdirect print server.
NOTE: If you are configuring an HP Jetdirect wireless print server, this section assumes that a
wireless network connection is established.
