BOOTP Troubleshooting

If the BOOTP request is failing and you have configured your host to respond to the request, check these areas:

	Table 6-3. BOOTP Troubleshooting
Area to Check	Explanation
BOOTP is in your system's	BOOTP must be an uncommented line in /etc/services.
/etc/services file.

The MSS is in the loadhost's /etc/hosts file.

The download file is in the correct directory and is world- readable.

The MSS and host are in the same IP network.

The MSS must be in this file for the host to answer a BOOTP or TFTP request.

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 filename.

Some hosts will not allow BOOTP replies across IP networks. Either use a host running a different operating system or put the MSS in the same IP network as the host.
