Troubleshooting gated

If gated is not operating properly, use this section to identify and correct

the problem.

Troubleshooting Tools and Techniques

This section describes the available tools for general troubleshooting of

gated.

Checking for Syntax Errors in the Conﬁguration File

After creating or modifying a gated conﬁguration ﬁle, you should start

gated from the command line with the -C option. This option causes the

conﬁguration ﬁle to be parsed for syntax errors.

gated Tracing

gated prints information about its activity in the form of tracing output.

This information includes routes that gated reads, adds, and deletes

from the kernel routing table, as well as packets sent and received.

You can specify tracing either with the gated -t command line option

or with the traceoptions statement in the /etc/gated.conf ﬁle.

Using any of the following combinations, you can determine where the

tracing output is printed and whether tracing is performed:

• If you specify trace options and a trace ﬁle, tracing output is printed

to the log ﬁle.

• If you specify trace options but do not specify a trace ﬁle, tracing

output is printed on the display where gated was started.

• If you specify a trace ﬁle but do not specify any trace options, no

tracing takes place.

NOTE With version 3.5 of gated, the two statements previously in the Trace

class (tracefile and traceoptions) have been combined into one

traceoptions statement. So, the tracefile statement has been

eliminated. For details about the new syntax, type man 4 gated.conf

at the HP-UX prompt.
