Meaning it crashes? Seems strange, you'd think Checkpoint would have tried a UDP packet before they shipped... Can anyone else confirm the results?
Indeed, I'd love if someone could do more testing. I've blown away my RH7 install, and am working on 6.2 right now -- bad kernel (Default). So far no remote udp crashes. Haven't done much configuration yet, though.
If I run nslookup on nmap_source, set my server tofw_under_test, andattempt to resolve something (even though fw_under_test isnot running anameserver), the fw_under_test does not crash. It merelyreplies with udpport unreachable and stays up.Must be something in particular with the conetns of the packet NMAP sends.
According to nmap man pages, it sends 0 byte udp datagrams. -Yanek.
