Raspberry Pi VPN Router

This is a quick-and-dirty guide to setting up a Raspberry Pi as a "router on a stick" to PrivateInternetAccess VPN.

I've been playing with jq, and I've been having a hard time finding examples of how it works with output from a service like AWS (which I use a lot).

Here is one I use a lot with vagrant-ec2.

When we're launching and killing a lot of instances, the AWS API is the only way to track down which instances are live, ready, dead, etc.

To find instances that are tagged with e.g. {"Key" = "Name", "Value" = "Web-00'} in the middle of a vagrant dev cycle, or a prod launch/replace cycle, you can do something like this:

	# Automatically instal the latest nginx
	wget -O - http://nginx.org/keys/nginx_signing.key \| sudo apt-key add -

	#Make a backup copy of your current sources.list file
	sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

	#Now copy the following repositories to the end of ` /etc/apt/sources.list`
	echo "deb http://nginx.org/packages/mainline/debian/ jessie nginx" \| tee -a /etc/apt/sources.list
	echo "deb-src http://nginx.org/packages/mainline/debian/ jessie nginx" \| tee -a /etc/apt/sources.list
