Finding out which and how many connections are made by our computer can be very useful even if the programs that allow you to analyze the connections are often complex to use. However, we have discovered a very interesting free alternative called Sniffnet.
We say interesting alternative because it is an application that is actually very easy to use and even reading the various results can be within the reach of almost everyone. And in this regard one of the most interesting things about Sniffnet is the fact that it is multi-platform: it is in fact possible to install it on Linux but also up Windows come on macOS.
Sniffnet, discover the connections made by your computer
The program, as mentioned, is really very simple. First of all you need to select the active network card and the one you want follow at that moment, especially if you have more than one. You can run it (by pressing the rocket button!) as it is by default while the more experienced can make some changes such as applying some filters on the type of protocol they are interested in following and whether to search for IPv4 or IPv6.
By default you will immediately see traffic appear on your screen with traffic going out (in blue) and traffic in (in red). Just below you can see the various protocols used and the host you are connecting to.
By selecting the single host you can then go to the Inspect table to see the individual connections that are made to that host where the nationality of the server is also reported.
Download the program
It is therefore in our opinion a very useful application for trying to understand the connections that are made by our computer, with a little practice and patience we are sure that it could be useful to many of you!
