Is there any way to send to a specific log file?

Netfilter logs come as normal kernel messages, so you can't select by
facility.priority. I'd recommend using something like syslog-ng which
allows you to filter per regexp, or to use some post-processing
facility.

What do the users of this list use to read the log files? I have tried Spacewalk (which is nice) but is a lot of software to install to read logs. I have looked at Prewikka but do not have it totally configured yet to give it a OK or not.

My experiences (I assume you specifically mean the audit logs):

Prewikka would be for IDS events only with the prelude plugin.
I use the audit-viewer with pre-constructed list tabs to match events
necessary for verification testing.
For faster results when looking for specific events or investigation, I
use the command line tools aureport and ausearch.

What would be great IMHO is to have a prewikka-like web interface for
the audit events.

I also used the au tools (aureport, aufind, etc) but just wanting a average user to view the bad events brings the need of a point a click interface. The people that now read the audit events for the windows servers are spoiled by the cornerbowl tool. I tossed together a little script that dumps the audit events into a array, then sorts them and dumps them out but the users want a red background for bad and so on. Before I went crazy trying to put something together I wanted to see what was out in the wild. I guess something that dumps the files into a MySQL tables would be the easiest to work with.

The audit log files are intended to be read with ausearch. You can also use vi or less 
or emacs as long as you don't change anything. :)  But ausearch has more knowledge 
about the logs and can make it easier to understand. 

The aureport tool can give columnar and summary information about the logs. It can 
also take the raw output of ausearch as input if you want to do anything fancy. (See 
the http://magazine.hackinthebox.org/issues/HITB-Ezine-Issue-005.pdf article about the 
audit system for examples of combining ausearch and aureport.)

Aulast can tell you about login sessions and give you command line queries to extract 
information about a particular login session. (This is newer and not available in 
older audit package releases.)

As for syslog and application log files, I'm sure there are a lot of tools.

There is a audisp plugin for prelude:

$ repoquery -qf /sbin/audisp-prelude
audispd-plugins-0:2.1.2-1.fc16.x86_64

The plan would be to rotate the log at midnight Saturday, use the
aureport to read the file and give it some kind of format, dump the data
into a mysql database, then parse it with php on a apache server with a
firefox front end. Or something like that.

OK; that was my thinking as well.
Only I roll mine up each day already and move them out of the way.

I think you would likely use a custom program which used the parse libs
to extract the searchable elements from each event.

What I was wondering is if on the front end (cgi+browser-side) you had
something in mind which existed already - or if you would code it up
from scratch with the php-mysql piece?

Thx,

All I know is the PHP/MySQL stuff so that would be the plan. I only asked on the list to see if someone already started it or if something is out in the wild. The module for Spacewalk (and probably satellite) is nice and would probably use Joshua Roys's auc program to clean up the data. I have Prewikka installed on a spare RHEL5 server to test with but it seems that it needs to have something written to handle reading the audit log data. I only started to look at it and was mostly interested in Spacewalk because it is a RedHat program and would fit nicely in our RedHat shop. Using the LAMP stack would also make it easy to connect from anywhere with anything.
