Troubleshooting Network Boot Problems308614-14.20 Rev 00 B-15Note that /$HOME/.builder_dir/rel/an is the default location of thekernel file and all application and string files for the AN/ANH. The defaultlocation of the kernel file and all application and string files for the ARN is/$HOME/.builder_dir/rel/arn.5. Ensure that the bootptab file contains a definition for the router that isfailing to netboot.6. Ensure that the configuration file name and path are correct in thebootptab file.For example, the following bootptab entry indicates that the configuration filenamed AN_Bost.cfg is in the /rte3/cfg directory:T129="/rte3/cfg/AN_Bost.cfg"7. Read the bootptab file carefully for misspellings or other errors.Compare it with the sample file shown in Chapter 2 (see Figure 2-1 onpage 2-8).Displaying the BootP Server IP RoutesTo display the IP address of the next-hop router, enter the following command atthe UNIX command line of the BootP server:netstat -rn | grep -i -nIP_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 addressof the next hop to the network address 192.32.155.If the BootP server is receiving RIP advertisements of the netbooting router’snetwork, a message such as the following appears:121:192.32.155.0 192.32.13.53 UG 0 0 le0The 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 StaticRoutes to Next-Hop Routers” in Chapter 2.
