cargo install sniffnet --locked

from Homebrew

You can install Sniffnet Homebrew package with:

brew install sniffnet

from Nixpkgs

You can install Sniffnet Nix package adding the following Nix code to your NixOS Configuration, usually located in /etc/nixos/configuration.nix:

Troubleshooting

See details

Missing dependencies

Most of the errors that may arise are likely due to your system missing dependencies required to correctly analyze a network adapter.
Check the required dependencies page for instructions on how to proceed depending on your operating system.

Rendering problems

In some circumstances, especially if you are running on an old architecture or your graphical drivers are not updated, the wgpu default renderer used by iced may manifest bugs (the interface glitches, color gradients are unsupported, or some icons are completely black).
In these cases you can set an environment variable to switch to the tiny-skia renderer, a CPU-only software renderer that should work properly on every environment:

ICED_BACKEND=tiny-skia

In any case, don't hesitate to open an issue, and I will do my best to help you!
