Application to comfortably monitor your network traffic
Multithreaded, cross-platform, reliable
Sniffnet is a simple yet insightful application to analyse your network traffic in a straightforward and appealing way
Installation
You can install Sniffnet in one of the following ways:
from Crates.io 
Follow this method only if you have Rust installed on your machine.
In this case, the application binary can be installed with:
cargo install sniffnet
from GitHub releases 
You can install Sniffnet through the installers available in the latest release.
Choose between a Windows installer, a DEB package, or a macOS disk image (depending on your operating system).
from Homebrew 
You can install Sniffnet's brew package with:
brew install sniffnet
Required dependencies
Depending on your operating system, you may need to install some dependencies to run Sniffnet:
Windows dependencies 
In order to correctly run Sniffnet on Windows systems you need to:
Linux dependencies 
In order to correctly run Sniffnet on Linux systems, install the libraries and header files for the libpcap library:
sudo apt-get install libpcap-dev
Note that if you are not running as root, you need to set capabilities to inspect a network adapter:
sudo setcap cap_net_raw,cap_net_admin=eip <your/Sniffnet/executable/path>
Depending on your Linux environment you may also need libfontconfig:
sudo apt-get install libfontconfig libfontconfig1-dev
MacOS dependencies 
MacOS natively has all the dependencies you need to build and run Sniffnet!
Features
- choose a network adapter to inspect
- select filters to apply to the observed traffic
- view real-time charts about traffic intensity (bytes and packets per second, incoming and outgoing)
- view overall statistics about the filtered traffic
- view most relevant connections (most recent, most packets, most bytes)
- save complete textual report with detailed information for each connection:
- source and destination IP addresses
- source and destination ports
- carried protocols
- amount of exchanged packets and bytes
- initial and final timestamp of information exchange

Troubleshooting
See details
Missing dependencies
Most of the errors that can occur are likely due to your system missing required pcap dependencies,
necessary to correctly analyze a network adapter.
Check the required dependencies section for instructions on how to proceed.
For a Windows reference, you can check issue #1.
Some Linux systems also need libfontconfig, see issue #18 for a reference.
Installers incompatibilities
If you have problems after having installed Sniffnet through the provided installers,
it could be due to your OS not being compatible with the pre-built binaries I generated for you.
Reach me out, and I'll try to generate an installer for your specific operating system.
In any case don't hesitate to open an issue, and I will do my best to help you!
