rarpd daemon finds the host name, OKIPRINTER,
listed as the name associated with the network
hardware address.
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 Net-
work Print Server with the IP address
192.168.42.55. The Network Print Server will then
use this IP address for all subsequent transmis-
sions.
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 Network Print Server, make sure the following two
criteria are met for RARP to work properly.
1. Both the RARP server and the Network Print
Server are physically attached to the same subnet.
