View 1 Instructions for compiling node0.8.8 with hardfloat.md

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!!!)

systemd Service Unit for Traefik

Adapted from the forked gist and this blog. Adjusted to our own implementation.

The provided file should work with systemd version 219 or later. It might work with earlier versions. The easiest way to check your systemd version is to run systemctl --version.

Why only IPv6 will also listen for IPv4 on most Linux systems...
View explaination.md

The best approach is to create an IPv6 server socket that can also accept IPv4 connections. To do so, create a regular IPv6 socket, turn off the socket option IPV6_V6ONLY, bind it to the "any" address, and start receiving. IPv4 addresses will be presented as IPv6 addresses, in the IPv4-mapped format.

The major difference across systems is whether IPV6_V6ONLY is a) available, and b) turned on or off by default. It is turned off by default on Linux (i.e. allowing dual-stack sockets without setsockopt), and is turned on on most other systems.

In addition, the IPv6 stack on Windows XP doesn't support that option. In these cases, you will need to create two separate server sockets, and place them into select or into multiple threads.
