Troubleshooting configuration problems

This chapter provides information about simple troubleshooting procedures that are

designed to help you solve common DTC conﬁguration problems. It does not cover

procedures for resolving DTC hardware problems. Refer to your DTC hardware

manual for information about how to use the DTCs diagnostics port to troubleshoot

hardware problems.

Troubleshooting overview

Before you begin troubleshooting, answer the following questions to help locate the

possible source of the problem:

• Does the problem seem isolated to a particular user or to a particular program?

• Can the problem be reproduced?

• Does the problem affect all users on a specific DTC, a specific board on a DTC,

or a specific port on a DTC?

The dtcdiag command can help you isolate the problem to a speciﬁc board or port

on a DTC.

Troubleshooting procedures make use of the dtcdiag, dtcping and dtccheckip

commands which are explained in chapter 13. If error messages are displayed when

you try to run dtcconﬁg, dtcdiag or dtcping refer to “Solving dtcconﬁg, dtcping

and dtcdiag problems” in this chapter.

Problems with DTC communication are likely to be a result of trouble with one of

several distinct subsystems.

• Faulty DTC hardware.

If you suspect a DTC hardware problem, consult the DTC hardware manual.

• Improper or invalid DTC configuration.

• Improper functioning of Internet services on the destination host.

• Improperly installed DTC Manager/UX software.
