HP-UX Desktop Troubleshooting Guide

# ps –ef | grep X
If X is running, try the following xclock test to verify that the local X does not have
any problem. To invoke the xclock test, complete the following steps:
1. Establish a telnet connection to the HP Server.
2. Run the init 2 (or) /sbin/init.d/dtlogin.rc stop command.
3. grep for X and dtlogin process and kill them, if any.
4. Start X by running the /usr/bin/X11/X :0 & command.
5. Run the export DISPLAY=<HP Server IP>:0.0 command.
6. Run the xclock & command. A window with a real time clock image on the HP
Server graphics console appears.
If the xclock test case passes, it indicates that the local X does not have any problem.
If the above xclock test fails, repeat the same steps for xclock. Replace step Step 4
as
# /usr/bin/X11/X :0 -ac &. Check the existence of X.
If X starts, the problem may be related to authorization and further analysis is required.
5.1.5 Check problems related to DNS
Check the permissions of the /etc/hosts and /etc/nsswitch.conf files (the file
must have minimum read permissions for the owner, others, and the group). Also
check the /etc/nsswitch.conf file for the following entries, depending on the
version of the Operating System.
• If the Operating System version is 11.11, check for the hosts entry in the
nsswitch.conf file.
This may be:
— hosts: dns [NOTFOUND=continue] files : This indicates that DNS will first
try to resolve the hosts entry. If it is not able to do so, the /etc/hosts file will
be checked.
— hosts: files [NOTFOUND=return] dns : This indicates that the /etc/hosts
file will be checked first to resolve the hosts entry. In this case, DNS will not
be checked if the /etc/hosts file is unable to resolve the entry.
• If the Operating System version is 11.23 or higher, check for the following entries
in the nsswitch.conf file:
hosts entry may be:
— hosts: dns [NOTFOUND=continue] files
— hosts: files [NOTFOUND=return] dns
