Troubleshooting Network Boot Problems

A-11

If you enter this command after a Technician Interface prompt, save the change to

the conﬁguration ﬁle in the ASN’s ﬁle system by entering the command

save conﬁg 1:

<conﬁg >

(

conﬁg

is the name of the conﬁguration ﬁle.) Otherwise, the change is lost when

you boot the ASN.

Debugging the BOOTP Server

Debug the BOOTP server as follows:

1. Enter the following command at the UNIX command line:

bootpd -s -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 Chapter 2 (Figure 2-1) and correct the error.

4. If you cannot ﬁnd an inconsistency, boot the ASN and view the bootpd

debugger messages to determine the cause of the error.

Note: If you have not set up the network to Netboot the conﬁguration ﬁle, an

ASN’s attempt to get the ﬁle over the network will continue for approximately 4

minutes; then the ASN will local boot the ﬁle. However, if your primary

interest is Local Boot for routine startups, you can avoid this long wait by

specifying

bconﬁg conﬁg local after the Technician Interface screen

activates.
