HP-UX Diagnosing and Debugging
Simple Network Debugging
If network boot is used on a local subnet and the Ignite-UX server is not found, check these items:
• Verify the client is on the same subnet as the Ignite-UX server or boot helper.
• Investigate instl_bootd errors in /var/adm/syslog/syslog.log.
• In the /var/adm/inetd.sec file, ensure the service instl_boots exists, and that the IP
address 0.0.0.0 is allowed. (Normally, all addresses are allowed via 0.0.0.0.) The entry
should look like:
instl_boots allow 0.0.0.0
• If /etc/services comes from NIS, make sure the NIS server has instl_boot* entries.
Logging to syslog.log
The bootpd and tftpd daemons have the ability to log requests and responses. The /etc/
inetd.conf file may be modified to enable logging. The bootpd -d option and tftpd -l
option control logging. For example:
# tftp dgram udp wait root /usr/lbin/tftpd tftpd \
-l /opt/ignite /var/opt/ignite
# bootps dgram udp wait root /usr/lbin/bootpd bootpd -d 9
The daemons log to the HP-UX syslog file located at /var/adm/syslog/syslog.log.
NOTE: Logging should normally be disabled since it can consume a significant amount of disk
space.
If the boot configuration includes multiple boot servers (for bootp relay, for example) it is often
useful to enable logging on all servers.
Using bootpquery
To save time when configuring an HP-UX system boot, the bootpquery command may be used
to simulate a network boot request by requesting bootpd to indicate how it would respond to
boot requests for a specific MAC address. This is normally much faster and simpler than attempting
to boot using a real client system.
To use bootpquery, add the ba option to the appropriate entries in the /etc/bootptab file.
Without this option, bootpd will send responses only to the client system making the boot request.
The ba option requests the response be broadcast on the subnet, so any system is able to see the
response, including the system where you are using bootpquery. For more information, see
bootpquery(1M).
NOTE: The ba option should be removed once testing is completed.
The bootpquery output includes valuable debug information:
# bootpquery 0011855F549E
