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.

C Wrapper

Add this to your Cargo.toml:

[dependencies]
netinfo = 0.5.1

Install Rust and Cargo, then call:

# This will create the binary `~/.cargo/bin/netinfo`
$ cargo install netinfo

To avoid Permission denied errors, you will either have to run the progam as root or allow the program to capture the network traffic:

sudo setcap cap_net_raw,cap_net_admin=eip /path/to/your/bin
