README

This project is thought as a simple example to show how to work with network namespaces using the rtnetlink Rust crate.

It will simply try to create a new network namespace and turn up the lo interface.

Usage

1. Build with cargo: cargo build
2. Run with sudo: sudo ./target/debug/run_in_ns test

If you do not want to run it as super user on your main system please consider creating an unprivileged user namespace, like for example:

unshare -f --user --map-root-user --net  --mount /bin/bash
mkdir /tmp/netns
mount --bind /tmp/netns /var/run/netns
./target/debug/run_in_ns test

Issue

Currently the program seems to deadlock during th retrieval of the lo interface index:
