Creating a dynamic site-to-site VPN with OpenSwan on Ubuntu 10.04 on EC2

There are many tutorials floating around the web that almost get you a dynamic VPN in EC2. The goal of this tutorial is to be a one-stop-shop for this specific setup.

remove all but last 5. Run this from the releases directory.

Running redis using upstart on Ubuntu

I've been trying to understand how to setup systems from the ground up on Ubuntu. I just installed redis onto the box and here's how I did it and some things to look out for.

To install:

	#!/usr/bin/env python

	import sys
	import csv
	import argparse
	from pathlib import Path
	import chardet
	from urllib3 import encode_multipart_formdata

	csv.field_size_limit(sys.maxsize)

	## The Problem

	Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.)

	## The temptingly easy but ultimately wrong solution:

	Alter the port the script talks to from 8000 to 80:

	}).listen(80);
