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

TL;DR

Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024

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:

These instructions work for the Raspberry Pi running Raspbian (hard float) and create a hardware optimized version of NodeJS for the Raspberry PI, (and include a working install and NPM!!!):

1. Install Raspbian - http://www.raspberrypi.org/downloads

2. Install the necessary dependecies:

sudo apt-get install git-core build-essential

(If you just installed git then you need to administer your git identity first, else adding the patches below will fail!!!)
