For staters haveyou used Nmap also the host that is being scanned do you have a
firewall on it, and if so is it setup to drop any icmp packets?
If you use nmap with a no ping scann and then look for tcp fiirst then udp you
should get some results.
Nmap -P0 -sT
-sU for udp.

Subject: Port Scanning Issues
A Chairde,
Havin, some issues with scanning stacks on my system.
1. Using Superscan4 , I scan stack UDP-TCP 1-65534 , Sometimes I
get no ports open , another time I get 49159 UDP Ports open, only get port
report, no attempt made to open any ports ... , when get open ports , I always
get 49159 UDP Ports ...... , use the scanner at 250msecs , takes around 16
hours to finish.
2. Using Languard, Nessus and Retina , get different scans from each tool, any
ideas why, how do I find out real ports open.. differences can be 10,000 ports
