Thanks for your reply!
lsof is in my system as you can see. When I'm doing the "lsof -i : 49208" nothing is happening as you see in the image.
Here is the sniffer program, I have closed my webbrowser and the Router has timed out (17:33:59).
The Router then connects to Versiontracker (time.17:34:09) "versiontracker.com" was the last site I visited.
This is what makes me cray, must be something in the system that keeps the request from versiontracker to connect
This is how the "Network preferens panel" looks.
I have non of the programs you mention installed.
