Udp traffic is not as critical as tcp traffic.

Interesting thesis.

That's what I gathered from various sites while googleing. But you seem to disagree. As a relative greenhorn I would welcome more details.

Nevertheless, I seem
not to be able to block some outgoing udp port 137 traffic
(netbios-ns) from my system. My PSF shows a listening state,
however no remote address (the executable is indicated as
"system").

listening is related to talking? e.g.: Why should there be any traffic
if there is just a process listening?

Because there are udp bytes sent. I wonder then where to?
