Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

	#!/bin/bash

	# Usage ./privconnect.sh 300 1.1.1.1
	# checks twice, 300 seconds in between, if the node the script is being run on
	# is connected to 1.1.1.1:9732. If it isn't trust then connect.
	# Run it from cron, make sure the cron interval is greater than the sleep period
	# between connection checks in this script. 2x or 3x the sleep period is good.
