Troubleshooting Network Boot Problems

A-13

For example, Version 2.12 of the Site Manager’s Image Builder tool stores the

Version 8.12 ﬁles in the /$HOME/.builder_dir/rel812/an directory.

2. Make sure that the AN/ANH extracts the kernel image and all of the

application and string ﬁles from the same software image.

If these ﬁles are from different software versions, the AN/ANH may fail to

boot or operate properly.

3. Make sure that the bootptab file is in the /etc directory.

4. Make sure that the bootptab file contains the following entries:

general:\

:hd=/$HOME/.builder_dir/rel812/an:\

:bf=krnl_an.exe:\

:bs=auto:\

:vm=rfc1048:

Note that /$HOME/.builder_dir/rel812/an is the default location of

the kernel and all application and string ﬁles.

5. Make sure that the bootptab file contains a definition for the particular

AN/ANH that is failing to Netboot.

6. Make sure that the conﬁguration ﬁlename and path are correct in the

bootptab file.

For example, the following bootptab line indicates that the configuration file

named AN_Bost.cfg is in the /rte3/cfg directory path:

T129="/rte3/cfg/AN_Bost.cfg"

7. Read the bootptab file carefully for misspellings or other errors.

Compare it to the sample ﬁle shown in Cha

pter 3 (refer to Figure 3-1).

Displaying the BOOTP Server’s IP Routes

Enter the following command at the UNIX command line of the BOOTP server to

display the IP address of the next hop to a netbooting router:

netstat -rn | grep -i -n

<IP_address>

is the IP address of the netbooting router’s network.

| is the vertical bar key (the UNIX pipe command).

For example, enter

netstat -rn | grep -i -n 192.32.155 to display the IP address

of the next hop to the network address 192.32.155.
