Troubleshooting Network Boot Problems
A-11
The possible settings for Ethernet connectors are as follows:
•
None (the default setting)
• The IP address with subnet mask
See Cha
pter 5 for instructions on using the ifconfig and bconfig commands to
change the parameter settings.
Debugging the BOOTP Server
Debug the BOOTP server as follows:
1. Enter the following command at the UNIX command line:
bootpd -d -d&
The bootpd debugger tool reads the /etc/bootptab file and generates the
/etc/bootpd.dmp file. The /etc/bootpd.dmp file contains the portion of the
/etc/bootptab file that the bootpd debugger could read successfully. The
debugger displays messages such as the following:
[1] 12914
hostname:/etc> reading "/etc/bootptab"
read 19 entries from "/etc/bootptab"
dumped 19 entries to "/etc/bootpd.dump".
2. Compare the bootptab file to the bootpd.dmp file.
If the bootpd.dmp file is truncated or is otherwise different from the bootptab
file, BOOTPD may have encountered a syntax error. Find the inconsistency in
the two files.
3. Compare the inconsistency in the bootptab file to the sample bootptab file
in Cha
pter 3 (refer to Figure 3-1) and correct the error.
4. If you cannot find an inconsistency, boot the AN/ANH and view the
bootpd debugger messages to determine the cause of the error.
The sample messages in T
able A-1 show the sequence of messages when a
BOOTP exchange is successful.
