--It is still useful to have a firewall (software or hardware) especially if you have other machines connected to your network that can access the Internet. If you are still using a regular old hub, STOP - and buy a switch. 5-ports can be had for ~$25 US, and 8-ports ~$30-35. Switches also increase network thruput by enabling full-duplex.

--If by some strange chance you are using XP to connect to the Internet and have ICS (inet conn sharing) enabled, your Knoppix box should obtain its IP addr from XP and you can go from there.

--Software firewall for Windoze: http://www.zonealarm.com - it's a free download.
