4. Click on the SUBMIT button when done. Using RARP RARP allows you to dynamically assign an IP address to the Ethernet Interface upon bootup. To configure the Ethernet Interface with its TCP/IP settings using RARP: 1. On your RARP server, make an entry in the /etc/ethers file for the Ethernet Interface. Syntax: ethernetaddress EthernetInterfaceIPaddress Example: 00:80:72:07:00:60 192.75.11.9 2. Start the RARP daemon on the RARP server if not already running. If it is running, send an HUP signal to it with the "kill" command: Syntax: kill -HUP pid where pid is the process ID of the RARP daemon. 3. Power on the Ethernet Interface so that it immediately sends out an RARP request. Wait one minute to allow the address assignment process to complete. You should see the STAT LED on the front of the Ethernet Interface slow down indicating it knows about an IP address to use. 4. Try to "ping" the Ethernet Interface IP address from a local Unix station to see if it can be seen on your network. NOTE: You will only be able to communicate with the Ethernet Interface from a network station on the same subnet as the print server. The Ethernet Interface needs to be told about a default router/gateway so any packets that come in from a different subnet can be returned via this gateway. Please see "Communicating Across Routers" on page 5-8 to set this up. 5-6 Unix Confuiguration

Using RARP
RARP allows you to dynamically assign an IP address to the Ethernet Interface
upon bootup. To configure the Ethernet Interface with its TCP/IP settings using
RARP:
1.
On your RARP server, make an entry in the /etc/ethers file for the Ethernet
Interface.
Syntax:
ethernetaddress
EthernetInterfaceIPaddress
Example:
00:80:72:07:00:60 192.75.11.9
2.
Start the RARP daemon on the RARP server if not already running. If it is
running, send an HUP signal to it with the “
kill
” command:
Syntax:
kill
–HUP
pid
where
pid
is the process ID of the RARP daemon.
3.
Power on the Ethernet Interface so that it immediately sends out an RARP
request. Wait one minute to allow the address assignment process to
complete. You should see the STAT LED on the front of the Ethernet
Interface slow down indicating it knows about an IP address to use.
4.
Try to “
ping
” the Ethernet Interface IP address from a local Unix station to
see if it can be seen on your network.
NOTE:
You will only be able to communicate with the Ethernet Interface
from a network station on the same subnet as the print server. The
Ethernet Interface needs to be told about a default router/gateway
so any packets that come in from a different subnet can be
returned via this gateway. Please see “Communicating Across
Routers” on page 5–8 to set this up.
