After installing Conky and listing all my inbound and outbound connections I start to wonder what's actually happening and what and why things are happening.
I'm getting a bit suspicious. How can I know which process is accessing which of these addresses?
If you only want to see those connections that arouse your suspicion you can really use lsof.
sudo lsof -i | egrep -i "cloudfront|poneytelecom|dark"
lsof -i restricts the output to internet connections.
Use egrep (instead of grep) to be able to supply alternatives in the search string (separated by |), -i tells egrep to ignore case (DARK vs. dark).
If you have IP-addresses instead of hostnames use
sudo lsof -ni | egrep -i "10\.0\.8|193\.170"
My favorite tool dealing with processes and network usage is nethogs (install it with sudo apt-get install nethogs).
This tool displays every process and the bandwidth it consumes, it doesn't show the IP-addresses where the processes are connecting though. You may have to start it with the interface name, e.g. sudo nethogs wlan0.
