I just set up a network for my desktop and my laptop (Netgear fast ethernet card in the Desktop and a Netgear WG311 wireless card in the laptop and linksys WRT54G broadband router). At first, I couldn't get the computers to see each other until I enabled "netbios over TCP/IP" and turned off the firewalls on both computers.
I went to the
web site and used the "ShieldsUp" tests to make sure the linksys firewall was adequately protecting my computers. When I ran the tests from my desktop, I passed all the tests. When I ran the same tests from the browser on my laptop (sharing the internet connection of course through the router) it was reported that my security system had tried to counter-probe the test site and thus was exposing itself (unsolicited packets received).
Since I posted my original message, however, I've run the test again and passed. I.e, it's no longer trying to counter-probe. I'm mystified.
I've learned also that I can set up my firewalls to allow certain exclusions so that my networked computers and router can do what they need to, but I'm in the early stages of leaning how to do this.
For now, I have to trust that my router is protecting my computers.
After all my rambling, do you perceive enough to give me any advice. I've already learned alot from reading your other replys to posts in this group.
I suspect he is talking about leaktest at grc. Leaktest is an 'extrusion' detector. It tries to simulate malware running on the user's computer. You download and run the app and it leaks thru' intrusion detectors.
