Chapter 4 Unix PrintNet Configuration
62
Using RARP
RARP allows you to dynamically assign an IP address to the PrintNet
upon bootup. To configure the PrintNet with its TCP/IP settings using
RARP:
1. On your RARP server, make an entry in the /etc/ethers file for the
PrintNet.
Syntax:
ethernetaddress PrintNetIPaddress
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 PrintNet 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 PrintNet interface
slow down indicating it knows about an IP address to use.
4. Try to “
ping” the PrintNet 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 PrintNet from a
network station on the same subnet as the print server. The
PrintNet 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 64 to set this up.
