Hi Folks;

I am kinda glad I hung around this list for a while...
I am running a FreeBSD 4.2-STABLE (recently upgraded machines) for web =
(Apache-1.39)mail (Qmail-1.03 sendmail-8.11.1).=20
I have recently seen some activities on the web server that make me very =
nervous (I know I am being very general) but my concern is:

1.  How do I setup a dedicated machine to collect data and connection =
attempts to my machines
2. How to implement a notification systems to alert when critical files =
on the server have been tampered with.
3. How to find out if my machines are REALY CLEAN (some sort of software =
auditing to determine if what is already in the machines is a good =
benchmark for future security audits)


Thank you!
