Central Audit Server with Prelude and Prewikka - RHEL5

[Dan Gruhn]

Steve,

Thanks for the advice.  I was wondering about duplicating those 
information streams and needed the encouragement to go ahead.

One thing that did come up, I changed a lot of "localhost" references in 
the "Audit + Prelude HOWTO" and in the /etc/prelude/default/client.conf 
files to my actual server name (master) and I also changed a line in 
/etc/prelude-manager/prelude-manager.conf from

listen = 127.0.0.1

to

listen = master

All of these changes required me to revoke my old prelude-manager 
registrations under "localhost" and re-register all of the sensors to 
"master".  Perhaps I didn't need all of this but it is all working now 
(except for my 5.2 SELinux problem).

I'm running prelude-lml on the master and I'll be figuring out if I 
should run it on each node or it will pick up everything from the 
master's /var/log/messages file.  I'm thinking it would be better to 
keep things separate but I'll be testing.

If anyone can tell me if some of those "localhost" changes were not 
necessary it would be helpful to know for future reference.  I could 
update the "Audit + Prelude HOWTO" with what I've found and send it to 
back to Steve if that would be useful.
