Greetings! I've written a whitepaper that explores some methods for host discovery, paying the most attention to discovering hosts behind a firewall with an explicit policy. It probably won't be terribly valueable to the seasoned pen tester, but I think it lays out the basics and should give you some ideas. I also wrote a perl script that implements the ideas presented. You can find the whitepaper at http://moonpie.org/writings/discovery.pdf and the perl script at http://moonpie.org/tools/discover.tgz I'm interested in hearing your comments :) Best Regards, - Mark http://moonpie.org ---------------------------------------------------------------------------- This list is provided by the SecurityFocus Security Intelligence Alert (SIA) Service.
