4.3.2 Debugging

The debug global statement sets the debugging level – an integer value that controls the verbosity of rush:

global: debug num

Set debugging level to num.

The greater num is, the more verbose is the logging. The debugging information is reported via syslog at facility ‘authpriv’, priority ‘debug’. As of version 2.2, the following debugging levels are supported:

1

A minimum debugging level, and the only one whose messages are logged using the priority ‘notice’. At this level, rush only logs requests and rules selected to handle them. For example:

rush[16821]: Serving request "/usr/libexec/sftp-server"
for sergiusz by rule sftp-savane

2

List all actions executed when serving requests.

3

When parsing a legacy configuration file, verbosely describe parsing process.

More debugging levels may be implemented in future.
