nmap is a great TCP SYN port scanner though! And since very little actually goes through UDP, its must better just to do an -sS scan and leave it at that...
If that doesn't return many open ports, then you can be "fairly certain" the system is "secure"
(Note the 2 sets of inverted commas in the above).

I agree with Rewandythal, and I wasn't trying to impune the honor of nmap. I use nmap on a regular basis at work, and as Rewandythal said , it works great for TCP, I just haven't been real impressed with the UDP scanning. I find it kind of unusual that nmap does so poorly with UDP scans, since all it takes to get better results is to insert a single character in the UDP packet when you send it. I guess fyodor has better things to do with his time (like making the TCP scans even stealthier).

I love nmaps stealth scanning... I could sit for hours scanning my own network!

yeah..that is strange..and that is one messed up network! try port scanner plus or YAPS(yet another port scanner)
