Sniffnet


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


Install and Run

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.

Windows dependencies 

In order to correctly run Sniffnet on Windows systems you need to:

  • Install Npcap.

  • Download the Npcap SDK.

  • Add the SDK's /Lib or /Lib/x64 folder to your LIB environment variable.

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>
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 Install and Run section for instructions on how to proceed.

For a Windows reference, you can check issue #1.

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!
