Firewall Availability QuestionI'm new to Linux. So, I don't know much about it. I am, however, trying to sort out the various versions in effort to find the best one, for me. I am trying to transform my P4 300Mhz dsl xp machine into a Linux server. So, does the Debian Linux come with a firewall pre-installed? I read a few posts, at this forum, but none were clear as to whether any version of Linux had its own firewall. Also, the server will likely only host my website, where visitors will read plus make postings, etc. So, I was wondering if the firewall, if any, would have to be altered/enhanced somehow? Any thoughts on these issues? - jazzy Bookmark/Search this post with:

Re: Firewall Availability Question
All 2.6 Linux kernels have an integrated firewall called iptables. It's very good, but can be a little intimidating for new users. Luckily, there are a few tools that can assist you in creating the firewall. Shorewall runs from the command line and is good for headless servers or servers you don't want to tie up with x-sessions. Firestarter is a fairly basic graphical front end that's very easy to use. Guarddog is another graphical front end that offers more versatility then firestarter but is a bit more complex. Google should give you some good How-tos on adding rules directly through iptables if you want to go that route.
