kazaa version 1 always use port tcp/1214 for downloading files ( its a http connection with some specific headers, but you can just browse the 'victim' shared files and download, even you are not connected to k. network - personally tested on k. 1.2.5 i guess ) kazza version 2 seems to auto-negotiate an arbitrary port ( maybe, like you said, somewhere near or above 3000 ) Alex
