Netinfo is a Rust library and command line application that groups network usage by process. It works in a nethogs-like way, so you don't need a special kernel module.
In comparison to nethogs, it also supports UDP connections.
Because it heavily uses the /proc-filesystem, only Linux is supported at the moment.
Add this to your Cargo.toml:
toml
[dependencies]
netinfo=0.1
To avoid Permission denied errors, you will either have to run the progam as root or allow the program to capture the network traffic:
bash
sudo setcap cap_net_raw,cap_net_admin=eip /path/to/your/bin
