RARP and BOOTP
Enabling RARP
RARP can be used to establish communications. The printer broadcasts its
Ethernet address across the network, and receives its internet address from
the Þrst host to respond.
1.
If the rarpd daemon is started within the /etc/rc.local Þle or a
similar startup Þle, it is always running and waiting for RARP
broadcasts. If the rarpd command line does not exist in your
/etc/rc.local Þle, you need to add it. To verify that the rarpd startup
command is in the Þle, type:
grep rarpd /etc/rc.local
If the rarpd startup command is in the Þle, this line is displayed:
/usr/etc/rarpd -a ;echo -n Õ rarpdÕ
2.
Verify that rarpd resides where it is speciÞed in /etc/rc.local. For the
preceding examples, rarpd would be located in /usr/etc. If there is a
mismatch between the actual location and the speciÞed location,
either move the rarpd binary or change the /etc/rc.local Þle.
3.
Edit the /etc/hosts Þle to add the printer internet addresses and
names. This example adds two Phaser 480 printers to the /etc/hosts
Þle:
128.07.60.30 P480-mktg
128.07.60.31 P480-sales
