Troubleshooting Network Boot Problems

B-15

Note that /$HOME/.builder_dir/rel<rel>/an is the default location of the

kernel file and all application and string files for the AN/ANH. The default

location of the kernel file and all application and string files for the ARN is

/$HOME/.builder_dir/rel<rel>/arn.

Ensure that the

bootptab

file contains a definition for the router that is

failing to netboot.

Ensure that the configuration file name and path are correct in the

bootptab

file.

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

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

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

Read the

bootptab

file carefully for misspellings or other errors.

Compare it with the sample file shown in Chapter 2 (see Figure 2-1 on

page 2-8).

Displaying the BootP Server IP Routes

To display the IP address of the next-hop router, enter the following command at

the UNIX command line of the BootP server:

netstat -rn | grep -i -n

<IP_address>

IP_address

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

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.

If the BootP server is receiving RIP advertisements of the netbooting router’s

network, a message such as the following appears:

121:192.32.155.0 192.32.13.53 UG 0 0 le0

The numbers in this message indicate the following:

•

121 is the number of the entry in the workstation’s static routing table.

•

192.32.155.0 is the IP address of the destination network.

•

192.32.13.53 is the address of the next-hop router.

If the next-hop router is unavailable or incorrect, see “Setting Up Static

Routes to Next-Hop Routers” in Chapter 2.
