Garret Howard: It's simpler then you think mate: in Little Snitch you check whether or not your Mac will ping back.
Open System Preferences/Little Snitch, Application: ping, tell Little Snitch to deny ICMP from any server at any port, and lock and close Little Snitch.
Now when you go back to Gibson en probe your ports you'll see you'll be - what's in a name? apples, mate :-) all ports will be stealth now.

How to make a Mac invisible?
My logs show that since I'm a happy Mac owner, the percentage of visitors using a Mac has risen. The average of Mac users in unique sessions is approximately 50 a day now. Must have something to do with search engines. Anyway; this might be the right place to ask the question: how do I make my Mac invisible?
On my previous old XP and Win 2K platforms, my machines passed the Shields Up test at Gibson Research with flying colors: totally stealth, totally invisible. The Norton Suite did the job wel, Firewall and anti-virus.
While I'm using Little Snitch and Virex I feel pretty safe, and all logs so far haven't showed anything that should worry me.
Having said that; I want to be invisible again. A quick search on the internet showed that I should check: Sharing/Firewall/Advanced/Stealth Mode.
Having done so, inviting Gibson again to touch me, see me, feel me, (and heal me!) the results were the same:
File sharing and common ports no problem, all closed. So far so good, but now in probing all service ports the machine fails:
Solicited TCP Packets: RECEIVED (FAILED) — As detailed in the port report below, one or more of your system's ports actively responded to our deliberate attempts to establish a connection.
Ping Reply: RECEIVED (FAILED) — Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet.
Now I know there's an awful lot of information on the Gibson site, but some of the stuff is right above my head, and apart form that, I havent't got the time to seek it all out.
I kow too that my problems will probably be fixed by installing Norton Internet Security for the Mac, but there must be a quick fix.
Probably a simple terminal command wich results in denying a ping request, and another one doing the same for that port response.
Anybody?

Going back to Gibson after Garrett's post:

1056 Ports Tested
ALL PORTS tested were found to be: STEALTH.
TruStealth: PASSED - ALL tested ports were STEALTH,
- NO unsolicited packets were received,
- NO Ping reply (ICMP Echo) was received.

Thanks, Garret, and Little Snitch
