Running BOOTP
There are two ways to run BOOTP:
■
If the bootpd daemon is started within the /etc/rc.local Þle or a
similar startup Þle, it is always running and waiting for BOOTP
requests. This method uses system resources at all times.

If the bootpd daemon is started within the /etc/inetd.conf Þle, it
starts bootpd only when a BOOTP request arrives, conserving
system resources.

1.
If the bootpd command line does not exist in your /etc/rc.local Þle,
you need to add it. To verify that the bootpd startup command is
in the Þle, type:

in the Þle, type:
grep bootpd /etc/rc.local
If the bootpd startup command is in the Þle, the following line is
displayed. The -s option speciÞes continuous execution.

/etc/bootpd -s ; echo -n Õ bootpdÕ
2.
Verify that bootpd resides where it is speciÞed in /etc/rc.local. For
the preceding examples, bootpd would be located in /etc. If there
is a mismatch between the actual location and the speciÞed
location, either move the bootpd binary or change the /etc/rc.local
Þle.

3.
The port numbers for BOOTP listening and replying must be set in
the /etc/services Þle. If they are not set, edit the Þle and add them.
To verify that the ports are set in the Þle, type:
the /etc/services Þle. If they are not set, edit the Þle and add them.
To verify that the ports are set in the Þle, type:
grep bootp /etc/services
If the ports are set in the Þle, the following line is displayed:
bootps 67/udp
bootpc 68/udp
