That’s the goal of this article :)
One feature of Douane will be to show, in real time, the network activities.
To show this activities, I’ve been inspired by Little Snitch, and I did 2 gauges to show in and out going traffic.
(I miss Little Snitch on Ubuntu, so that’s why I’m so inspired by it. But I will not do a clone only. I want more features.) As I’m a Ubuntu fan, I made it in order to be well integrated to Unity, but also to GNOME-Shell.
