Ok here goes. I just purchased a new PC running XP. I am a fan of Linux, I own Mandrake 7.2. I plan to partition the drive and install 7.2 again. I feel as though it is a good starter for me considering that I am still very new to Linux. What my major concern is right now is making the Linux OS secure. I have heard a lot about IP chains, is this a linux firewall? If so, could anyone point me in the direction of how to go about setting it up? I also have some other Linux software that came bundled on the disc that came with Maximum Linux security. My goal is to solely run Linux eventually on this computer. Any help or tuts, would be greatly accepted. Also could anyone show me a list of the command line lists for Linux? Peace.
