Hi biggwormer, Can you expand on that a little more? What exactly makes you think that there is a problem on your system? Generally, you can't describe a person trying to get into your computer by "who's port" or "who's udp"... If you could describe the situation a little more, I'm sure we could advise you.
I;m not sure if this is what you are looking for but; On finding a UDP connection in the activity window (bottom window) you can note the Remote IP address indicated there and type "Ctrl+W" to open the Whois window. Type in the IP address and leave the search type at automatic. This will show you the registered "owner" of the Network range containing the IP. (Keep in mind that in many cases the smallest registered owner for some networks will consist of thousands of IPs so it is not going to get you the user of that PC To identify what services use the specific UDP port you see in the log, you can go to any of the many Port Databases such as http://www.neohapsis.com/neolabs/neo-ports/ For doing a port query on something in the upper window just right-click on that entry and you can automatically query the PortExplorer PortDB HTH
Hi Biggwormer, if you see a connection in your PE upper GUI, you can rightclick such a connection and the menu opens for you with a Resolve that IP and the Whois as well what is local port or remote port and the service/process on your system it's connected to. This menu is connected to the Utilities menu on top. The port reference is rather actual for default trojan/services names on those ports. In that LookUp utility you can now also relate the IP to country! I love the fastness of those tools, no need to lose time on digging for and opening other tools on my system.
