I was using Wireshark in order to check the activity of an unknown client in my home network, and to my surprise, I found some strange connections established by my own computer. I disconnected all clients from the network but myself, rebooted my computer, logged in as root, didn't start any programs and ran wireshark again. To my surprise, the connections were still being made:
uTorrent transport protocol...? I don't have any torrent clients opened.
ps -e output:
And according to Debian's built-in
whois those IPs belong to SKY and AT&T. Other IPs that appeared later also belong to AT&T, and others belong to random companies in China and Taiwan.
How should I diagnose this and what could/should I do about it?
