B.3
BOOTP Troubleshooting
If the BOOTP request is failing and you have configured your host to respond to the request, check these
areas:
Table B-2:
DHCP Troubleshooting
Area to Check
Explanation
DHCP is enabled on the
Server.
Use the
Set Server DHCP Enabled
command.
If you manually enter an IP address, DHCP is automat-
ically disabled.
Make sure the DHCP server
is operational.
Check to see that the DHCP server is on and is func-
tioning correctly.
The Server gets its IP
address from the DHCP
server
Refer to the
DHCP Manager
on your DHCP server
for information about addresses in use. If the DHCP
server doesn’t list your Server IP address, there may be
a problem.
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 Server is in the load-
host’s
/etc/hosts
file
The Server 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 Server 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 Server in the same IP network
as the host.
