Port Scanning

[chy at genuity.com (Chuck Young)]

I'm not sure about sending mail to RegrettableError at netscape.net

Bill is that your email address?

Anyway, the answer(s) depend on the scan type and firewall you are running.
What will your firewall do if I send a TCP SYN or UDP packet or ICMP message
to an unserved port?

Thanks for reading this. Sorry if it's a dup: Netscape just crashed when I
tried to send it before.

I'm curious about port-scanning, and have a question. Suppose someone is
trying to find a hole in my firewall, and scans a port that I'm not
running. Won't their scan come up "negative" for that port?

TIA.
