I sent Jamie a request, and he sent me the code (thanks!) and I read it and indeed it's not real different from a lot of other synflooders out there (but it sure is the cleanest implementation I've seen). Someone from ISC ran it against F.ROOT-SERVERS.NET for a while, and while the gross CPU usage went up, the rate of DNS response generation did not change. Thus we concluded that a 4-CPU Alpha ES40 running Tru64 5.0 is "safe". -- Paul Vixie <[email protected]> SVP for Internet Services, MFNX M.I.B.H.
