A listing of the different reasons of UDP connection attempt to uT ?

My firewall Kerio PF 4.2.3 shows a great number of UDP connection attempts to uT, out from local port 5000 to 9999 and in to my ingoing TCP port

I don't understand why ! UDP connections are generally considered as "at risk of hacking"

I don't have DHT enabled on uT nor RSS

... Clients can attempt to contact you over UDP. I am aware BitComet does this as may Azureus when NAT Transversal is enabled.

I'm confused. If uTorrent is launching them it's not TO uT, it's FROM uT. You can't connect OUT to IN. >< Get TCPView from http://sysinternals.com set the refresh rate to 1 second and see which process is attempting to use UDP.

Yes I corrected my mistake before reading your post

Kerio and Seem give me already the list of the connection by process

Kerio gives a list of more than 100 connections I don't know if it's worth to install TCP View : ?

I accepted outgoing connections one hour ago and I notice an UDP connection established to a port 6771 as allready reported by a forumer on here and with no IP address (strange)

TCP View shows me that it's an UDP uT connection between my PC:6771 to no "address" and with no "state" mentionned

I'd hardly call anything from sysinternals "install". Though I will admit process explorer is pretty hefty at 3 MiB unpacked. TCPView is a graphical representation of the netstat and nbtstat utilities.

Btw, it's rude and silly to expand your theory of your problem outside your thread. Posting in other threads ... especially without reading them, doesn't help you.

But it is another problem allready exposed in this other thread http://forum.utorrent.com/viewtopic.php?pid=370623#p370623 by "Press start", member, with no answer

My principal question is about "Why UDP connections with uT ?"

and the second is why port 6771 sometimes ? in this other thread

two different subjects ! ! :) on one hand a question of general features of uT and on the other hand a particular problem with a suspicious connection on a particular port
