HP-UX Desktop Troubleshooting Guide

3 Basic System Checks

This document provides troubleshooting tips to resolve problems commonly

encountered by CDE users. However, we strongly recommend that the below-mentioned

basic system checks must be performed before proceeding to detailed troubleshooting

techniques.

1. Ping the HP Server from the remote machine. Ping the remote machine from the

HP Server by running the following commands:

• From HP Server: # ping <PC IP>

• From PC : # ping <HP-Server’s IP>

If you are not able to ping, check for:

• The LAN configuration by typing the command: # /usr/sbin/lanscan

(The Hdw State of the LAN cards connected should be UP.)

• The physical connection of network cables.

2. Try to establish the telnet connection with HP Server:

# telnet <HP-Server IP>

If you are not able to connect, check if the telnet service is running or not.

3. Enter # nslookup <server_ip> and # nslookup

<server_domain_name> command to verify the information related to name,

address, and aliases for HP servers. If you find any errors in the output of

nslookup, refer “Troubleshooting Problems related to Network” (page 16).

4. Check the run level of OS by issuing the following command on the telnet session:

# who –r

The run level for CDE to come up must be 3. If the run level of the operating system

is not 3, change the run level by running following command: # init 3
