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

Dapper Dan
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.

Linux / Firewall / PPPoE xDSL

ITR000
I am new to the Linux world and had a few questions regarding configuring a Linux box to act as a firewall as well as connect and maintain connection to my xDSL service. As mentioned I would like the Linux box to connect via PPPoE to my ISP (xDSL) and provide firewalling to the rest on my internal segment.

Stopping file access from the Internet

dsnd_medic
I kept an article some years ago when I first tried redhat 6. Now some years later I have decided to go back to linux and found this article. It states that if you added in the line ALL: ALL in the file /etc/hosts.
