How to: Allow Node to bind to port 80 without sudo

TL;DR

sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node

Important: your node location may vary. Use which node to find it, or use it directly in the command:

Coturn installation steps

Third-party libraries

If you are installing the coturn package in Debian, Ubuntu or Mint, or if you installing the "turnserver" port in FreeBSD, or if you are installing one of the supplied binaries in the "downloads" section of the project, then the OS and the third party packages are installed automatically. The instrudctions below are for those who are setting the TURN server from scratch.

Before installing and configuring the TURN server, the latest stable libevent library should be downloaded, built and installed:

$ wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz

As root, build and install the library with the usual:

$ tar xvfz libevent-2.0.21-stable.tar.gz
