Sniff, sniff, what is that? 🤔
|
|
|
|
Is that a suspicious network connection I see on my system? 🚨❌
|
|
|
|
You might be wondering how I could see the network activity on my system. Well, of course, some of the [system monitoring tools][2] should help. But, what if I want more details?
|
|
|
|
Well, I came across a nice tool **Sniffnet**. It is a neat **open-source app for monitoring network activity** in real-time, which also acts as a good alternative to the proprietary [GlassWire][3] like [Portmaster][4].
|
|
|
|
So, let's dig in!
|
|
|
|
### Sniffnet: Overview ⭐
|
|
|
|

|
|
|
|
Sniffnet is a **Rust-based** network monitoring tool that lets you track all the internet traffic through your system. It offers some pretty **useful features that a power user will most definitely like**.
|
|
|
|
When you first launch Sniffnet, you are shown a menu to select the **network adapter, filters, and application protocol**.
|
|
|
|
After you are done selecting, click on the rocket button to get started.
|
|
|
|

|
|
|
|
This is how the overview page looks; it shows all the current network connections, as well as a handy traffic rate graph for you to analyze the flow of traffic.
|
|
|
|
> 📋 You can choose to display data as bytes or as individual packets.
|
|
|
|

|
|
|
|
For a more in-depth look at your network connections, you can head to the '**Inspect**' tab.
|
|
|
|
Here you will be shown a list with all the important info, such as the IP address, number of packets, amount of data, the originating country, and more.
|
|
|
|
You can click on the individual connections to get a more detailed outlook.
|
|
|
|

|
|
|
|
**What if you want to filter the results for a more specific purpose?**
|
|
|
|
Well, then you can use the filter options under the 'Inspect' tab to filter the results according to your needs.
|
|
|
|
You can filter the list by; application protocol, country, domain name, and more.
|
|
|
|
Here's what it looks like:
|
|

|
|
|
|
Sniffnet can also show you a detailed report of a connection that can be exported in text format.
|
|
|
|
Simply click on the logo with a page/right arrow at the bottom-right to get started.
|
|
|
|

|
|
|
|
**What about the customizability?**
|
|
|
|
Well, Sniffnet has a decent set of settings for you to tweak.
|
|
|
|
The first one is the 'Notifications' tab, which allows you to set the behavior of notifications according to the various thresholds that can be set.
|
|
|
|

|
|
|
|
Then there are the themes that can be accessed via the 'Style' tab; Four options are on offer, with the Yeti Night being my favorite.
|
|
|
|

|
|
|
|
And finally, the 'Language' tab allows you to set an interface language of your choice.
|
|

|
|
|
|
So, wrapping up.
|
|
|
|
Sniffnet is a handy tool that gives a very detailed outlook of the network activity on a system.
|
|
|
|
You can use this to monitor your network.
|
|
|
|
Furthermore, compared to [Nutty][14], another network monitoring tool, Sniffnet is far more intuitive to use and set up in my opinion.
|
|
|
|
### 📥 Get Sniffnet
|
|
|
|
Sniffnet is available across multiple platforms including **Linux**, **Windows**, and **macOS**. You can head over to the [official website][15] to grab the package of your choice.
