Troubleshooting Tips
Chapter 5106
Whenever you receive an error message, follow the corrective action
supplied in the manpage for that service. The error message is preceded
by the name of the service. Table 5-2 shows the appropriate manpage to
consult for a description of the error messages.
If the server or the client is not an HP Integrity system, see the
appropriate user’s manual or system administration manual for that
system. There is not a standard naming convention for servers or
processes that activate the servers; however, you should be able to find
the information in the system’s documentation.
Services Checklist
Following is a services checklist to help you diagnose the problem:
• Answer the questions in the section “Characterizing a Problem” on
page 99 at the beginning of this chapter.
• Run the service to your own node. To do this, your node name and
Internet address must be in the /etc/hosts file. If the server is
successful, then the client and the server halves of the service
operate correctly. This provides a starting point to determine where
problems are occurring.
• Use the flowcharts that follow to help you identify what is causing
the problem.
