Application to comfortably monitor your network traffic
Multithreaded, cross-platform, reliable
Sniffnet is a simple yet insightful application to let you have a glance into your network traffic in a straightforward and appealing way
If you have Rust installed on your machine, the application binary can be installed with:
cargo install sniffnet
Otherwise, you can install Sniffnet through the installers available in the latest release.
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
- 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

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 Install and Run 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.
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!
