BOOTP Troubleshooting
If the BOOTP request is failing and you have configured your host to respond to the request, check these
areas:
Area to Check Explanation
Physical connection To test a non-PostScript printer use the Test Port 1
Count 100 command. This command will send 100
lines of test data to the printer.
Service characteristics Use the Show Service Local Characteristics
command from a network login to see if the desired
service is available and to verify that the appropriate
protocols are enabled on the service.
The IP address The IP address must be unique on the network. Many
problems will occur when there are duplicate IP
addresses on the network.
Queue Status and Port counters Use the Monitor Queue command to ensure queue
entries appear in the job list. If an entry does not
appear, refer to the appropriate host section in this
Appendix.
Use the
Monitor Port n Counters command to
verify that the counter is incrementing with each job.
If it is not, verify the connection between the network
interface and the printer.
Area to Check Explanation
BOOTP is in your system’s
/etc/services file
BOOTP must be an uncommented line in the /etc/
services file.
The network interface’s name is
in the loadhost’s
/etc/hosts file
The network interface’s name 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, a add a
default pathname to the download filename.
The network interface 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 operating
system or put the network interface in the same IP
network as the host.
