Hi,
Is it possible to start and stop the user written audit plug-in while auditd
and audispd running? As I understand, audispd is started by auditd. Audispd
starts the user plug-in program using their configuration files present in
/etc/audisp/plugins.d directory. Auditd and user plug-in are started and
stopped as part of auditd startup and stop. Is it possible to start the
user plug-in after the auditd is started and stop the user plug-in before
the auditd is stopped?
There is nothing that prevents you from sending a SIGTERM to the plugin if you
are root. The plugin will be restarted when the next event arrives to audispd.

You are the only person who has asked for it. I suppose it can be done in a
couple lines of code. But you still have the permissions of the directories
that hold the rules to correct. Easy to fix, but I think you might be
fighting the distribution's package manager which would set things back to
root every update.

If you have an old copy old the audit system (2.5.1 or earlier) then use
log_format = NOLOG. If you have a current copy, then use write_logs = no.
