Is LINUX the answer?

gewitty

I have a small home network, consisting of two desktops and a laptop (all running WIN XP Pro). The network runs both Ethernet and wireless. One of the desktops is dedicated to running just ZoneAlarm, AVG, SpyBot and a mailserver (MailTraq).

Better than Backtrack

Darksat

I have played with a lot of security tools on Linux and I am just wondering, is there any other distro out there as powerfull as Backtrack? The only other ones I like are PHLAX and Pentoo, but neither feel as smooth, or have the same tools.

Firewall of Choice?

Jimxugle

I'm thinking of running my own Linux (of course) based server and I'm looking for a firewall app that will let me block all but select ports (80, 21, 22, 25, etc. ) from all IP addresses. Also, It would be great if that same app could block IP addresses that I specify.

Virus protection for Linux

I've been fooling around with. Even though there is a slim chance we could get infected with something, you likely don't want to pass viruses along to our Windows friends. It might come in handy. The interface is console and very easy to use.
