Table B-3: BOOTP Troubleshooting
Area to Check
Explanation
BOOTP is in your system’s
/etc/services file
BOOTP must be an uncommented line in /etc/ser-
vices.
The ETS is in the loadhost’s
/etc/hosts file
The ETS must be in this file for the host to answer a
BOOTP or TFTP request.
The download file is in the
correct directory and is
world-readable
The download file must be in the correct directory
and world-readable. Specify the complete pathname
for the download file in the BOOTP configuration
file, or add a default pathname to the download file-
name.
The ETS and host are in the
same IP network
Some hosts will not allow BOOTP replies across IP
networks. Either use a host running a different operat-
ing system or put the ETS in the same IP network as
the host.

mand to see if there is a RARPD process run-
ning.
