I'm using SuSE 8.2, which I've just reinstalled after repartitioning my hard drive, and while I'm busily re-downloading updates and re-installing programs, I've realized that I don't really know if the firewall checkbox I chose when I was setting up my dialup connection is doing anything. Does 8.2 automatically set the firewall up right, or do I have to tweak it? If the latter, can anyone hold my hand through the process? Also, anybody know a good page for testing the firewall? I've used Symantec's security tester on the Windows side of things, but they don't support Linux. Are there any other steps I should take to make sure my box doesn't get hacked? I realize that just by using Linux I've taken the biggest step, but it'd be embarrassing to fall victim to something I could have stopped with a click or a few command lines...
