Re: Most important UDP ports?

[Pete Herzog <lists () isecom org>]

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.
