5 Debugging

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

Configuration: debug num

Set the 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 1.9, the following debugging levels are supported:


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

List all actions executed when serving requests.


Verbosely describe parsing of the configuration file.

More debugging levels may be implemented in future.
