HP-UX Internet Services Administrator's Guide (May 2010)

Error Messages
The error messages generated by a service as seen on the client can be generated by
the client or by the server. Error messages from the client occur before a connection is
completely established. Error messages from the server occur after a connection is
completely established.
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 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” (page 75) 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.
