Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

Sniffnet v1.4.2

Free and open source application to comfortably monitor your Internet traffic.
Multi-threaded, cross-platform, reliable.

Sniffnet is a network monitoring tool to help you easily keep track of your Internet traffic. Whether you want to gather statistics, or you need to inspect more in depth what's going on in your network, this app will get you covered.




What makes Sniffnet unique?
Sniffnet is a technical tool, but at the same time it strongly focuses on the overall user experience: most of the network analyzers out there are cumbersome to use, while one of Sniffnet's cornerstones is to be usable with ease by everyone.

Furthermore, Sniffnet is completely free and open-source, dual-licensed under MIT or Apache-2.0.

Last but not least, this application is totally developed in Rust: a modern programming language to build efficient and reliable software, emphasizing performance and safety.

Features:
💻 choose a network adapter of your PC to inspect
🏷️ select a set of filters to apply to the observed traffic
📖 view overall statistics about your Internet traffic
📈 view real-time charts about traffic intensity
📌 keep an eye on your network even when the application is minimized
📁 export comprehensive capture reports as PCAP files
🔎 identify 6000+ upper layer services, protocols, trojans, and worms
🌐 find out domain name and ASN of the hosts you are exchanging traffic with
🏠 identify connections in your local network
🌍 get information about the country of remote hosts (IP geolocation)
⭐ save your favorite network hosts
🕵️‍♂️ search and inspect each of your network connections in real time
🔉 set custom notifications to inform you when defined network events occur
🎨 choose the style that fits you the most, including custom themes support
...and more!

Dependencies:

Windows dependencies
• Install Npcap, making sure to check the box Install Npcap in WinPcap API-compatible Mode during the installation.
• Download the Npcap SDK.
• Add the SDK's /Lib/x64 (or /Lib) folder to your LIB environment variable.

Linux dependencies
On Debian-based distributions:
libpcap-dev
libasound2-dev
libfontconfig1-dev
libgtk-3-dev
On RPM-based distributions:
libpcap-devel
alsa-lib-devel
fontconfig-devel
gtk3-devel

If you just need to run the app, the -dev / -devel part of the dependencies is not needed (it's required only for the build).

Note that if you are not running as root, you need to set capabilities to inspect a network adapter:

Alternatively, you can run the app with sudo privileges:
sudo sniffnet

macOS dependencies
MacOS natively has all the dependencies you need to build and run Sniffnet!
However, remember to run the app with administrator privileges: this is needed to analyze the activity of your network device.
