Best scanning software?

[Neurotica]

Hey, to all the other system admins, besides checking manually, whats the best scanning software you've used?

The gimp xsane plugin.


Oh, you mean port scanning?

I think there was a list posted to www.mandrakeforum.com (http://www.mandrakeforum.com) not too long ago.

I mean system scanning software, checking for insecurities, root kits, back doors, port scanning, etc..
