OKI OkiLAN 6120e User’s Guide
4. The rarpd then consults the “/etc/hosts” file and
looks up the name OKIPRINTER. It finds an IP
address (in this case 192.168.42.55) associated with
the name OKIPRINTER.
5. The rarpd daemon transmits a response to the
OkiLAN 6120e with the IP address 192.168.42.55.
The OkiLAN 6120e will then use this IP address for
all subsequent transmissions.
For all these steps to work properly, at least one RARP
daemon (rarpd) must be running on the RARP server.
On most UNIX systems, this can be tested by using the
ps command with the show all processes option.
Unfortunately, the ps options differ from one UNIX
workstation to another. Perform a man ps at the UNIX
prompt to consult a manual page on the ps command
for a particular workstation. If rarpd is not running on a
workstation, type man rarpd at the UNIX prompt to
consult a manual page on the RARP daemon and how
to start it.
Limitations
Often TCP/IP networks are divided into subnets. RARP
does not work across subnets. When installing an
OkiLAN 6120e, make sure the following two criteria
are met for RARP to work properly.
1. Both the RARP server and the OkiLAN 6120e are
physically attached to the same subnet.
2. The IP address assigned to the OkiLAN 6120e and
the IP address of the RARP server belong to the
same subnet.
