Hi,
You only have time constraints if you test UDP ports looking for ICMP
replies. However if you actually look for UDP services with UDP protocols
your tests can fly! I suggest you look into Unicornscan and other tools
which will test UDP ports with known UDP protocols on the standard ports
where you may find them. This doesn't help in finding "unknown" services or
those on strange ports but neither will scanning only known service ports
looking for ICMP replies. On the other hand, if the servers are configured
correctly and don't respond with ICMP then at least you can still find
active services.
Sincerely,
-pete.
