I'm aware of nmap, thanks. The problem is that my code above shows _no_difference_ between a closed and an open UDP port. I understand that I might have to try timing out, and that I might have to lump all "connection failed" responses together, and I'm completely fine with that.

Edit: Holy cow. I just realised that gman and I joined PM about 2 weeks apart. Almost 10 years ago!
