Using RARP
113
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 Ethernet Interface slow down, to indicate that 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 115 to set
this up.
