Hmmm, I seem to have both setroubleshoot and setroubleshoot-server
packages installed, but much of that package talks about turning on the
setroubleshoot service; the file for that should be in
/etc/rc.d/init.d/setroubleshoot, but I have no such file. Both packages
verify as correct (rpm -V) and rpm -qil does not show any such file in
the inventory. There is a file /usr/sbin/setroubleshootd which is what I
would expect for the daemon, but no file in /etc/rc.d/init.d references
it. Odd. And if I try to manually launch it, it runs briefly, leaves a
zero-length log file in /var/log/setroubleshoot/setroubleshootd.log.

Note that I am *not* on a X11 desktop on this host. It is a server, and
while it has X installed, it is in run level 3.

Actually, you don't need to have any of the setroubleshoot packages installed to get AVC messages logged. What you need is auditd running and it will log AVC messages to /var/log/audit/audit.log

With setroubleshoot-server installed you can watch the logged messages using:

# sealert -a /var/log/audit/audit.log

The output will be long and in the style of setroubleshoot browser, so take your measures.

Another tool - from the audit package - that can prove very useful is ausearch. It will search the audit logs for messages matching the given criteria.
