Post subject:  Security

Twice I've come into my computer room to discover that the activity light is blinking and the hard drive is clicking away furiously......The screen saver was gone the first time but intact the second time....

I have all the server programs installed but firewalled !!!

The only trusted chechkmark is beside eth0...

What am I missing ????

It could be that a cron program is running. Like each night the `locate` database is rebuilt, man pages are fiddled with, logs are moved (weekly), etc.

You can run:

Code:
ps ax


to see what is running. It's quite unlikely (but not impossible) that you have a security problem causing it. Also, look through your logs in /var/log/*

If you're really paranoid, you can run:

Code:
cd  /usr/lib/chkrootkit-0.43
chkrootkit


This will hunt around and check for root kits.

Again, I doubt this is security related. :)
