Quite a number of people have been asking me about ipsrvtrace. It's a tool I wrote a few months ago, to investigate a service-specific black hole. (Packets to one net to port 80 didn't get through; packets to other ports or other nets did, and the network manager insisted that there were no firewalls or transparent proxies in the way.) Anyway -- the code is not (yet) released. It runs on NetBSD, FreeBSD, and OpenBSD; a variant runs on Linux, but I haven't folded the Linux changes back into the base version yet. If you need that sort of functionality today, use tcptraceroute, which you can find at http://michael.toren.net/tcptraceroute --Steve Bellovin, http://www.research.att.com/~smb Full text of "Firewalls" book now at http://www.wilyhacker.com
