how vulnerable is your computer?

[datasuspect]

my results:

"Your system has achieved a perfect "TruStealth" rating. Not a single packet — solicited or otherwise — was received from your system as a result of our security probing tests. Your system ignored and refused to reply to repeated Pings (ICMP Echo Requests). From the standpoint of the passing probes of any hacker, this machine does not exist on the Internet. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system wisely remained silent in every way. Very nice."

1. I don't meet all of its requirements

Well, first they assume I'm running a Windows box. I don't have a Windows machine anywhere in my house.

My main computer is a Linux box. I also have my Linux server, which acts as my DNS and Gateway, through which my main computer (and my wife's Mac's) connects to the internet. I fail because my server has some ports open; these are ports I've set to be open, as it's a web/ssh/ftp server. My main computer has no ports open, because it doesn't act like a server in any way.
