Hi,

I am running the Sygate firewall on my system, which is running Windows 2000 Professional. I have blocked nearly all the applications or put an 'Ask' option before any applicatoin starts, except for the generic ones.

I am on a LAN connection. However, recently, over an IP scan (don't know which scanner was used), all the IPs of my dorm were detected (most of us use Sygate et al). The person who did the scan was also able to tell us about whether we were using Linux or Windows. I thought that a firewall does not disclose the OS information to an outside scanner.

Also none of us, who are running Windows, got any attack logs in our firewall log files. Can you tell me how this is possible, what kind of scanner was the person using and what are the steps needed to block such information disclosure in future.

Thanks and Regards,
Bluzky.
