Let's Encrypt on Ubuntu 14.04, nginx with webroot auth

This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt.

As it is not possible to change the ports used for the standalone authenticator and I already have a nginx running on port 80/443, I opted to use the webroot method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com and example.com).

Configuration

For this, I placed config files into etc/letsencrypt/configs, named after <domain>.conf. The files are simple:

default.conf

server {
    listen 443;
    server_name homelab.example.com;

    access_log /var/log/nginx/homelab.example.com.access.log;
    error_log /var/log/nginx/homelab.example.com.error.log;

root /var/www/html;

How To Run OpenVPN in a Docker Container

Introduction

This tutorial will explain how to setup and run an OpenVPN container with the help of Docker.

OpenVPN provides a way to create virtual private networks (VPNs) using TLS (evolution of SSL) encryption. OpenVPN protects the network traffic from eavesdropping and man-in-the-middle (MITM) attacks. The private network can be used to securely connect a device, such as a laptop or mobile phone running on an insecure WiFi network, to a remote server that then relays the traffic to the Internet. Private networks can also be used to securely connect devices to each other over the Internet.

Docker provides a way to encapsulate the OpenVPN server process and configuration data so that it is more easily managed. The Docker OpenVPN image is prebuilt and includes all of the necessary dependencies to run the server in a sane and stable environment. Scripts are included to significantly autom

	# This is a helper script that keeps snapraid parity info in sync with
	# your data and optionally verifies the parity info. Here's how it works:
	# 1) It first calls diff to figure out if the parity info is out of sync.
	# 2) If parity info is out of sync, AND the number of deleted files exceed
	# X (configurable), it triggers an alert email and stops. (In case of
	# accidental deletions, you have the opportunity to recover them from
	# the existing parity info)
	# 3) If partiy info is out of sync, AND the number of deleted files exceed X

	== ESXi on Gigabyte GA-Z97N-WIFI ==
	Default driverset of ESXi5.5 doesn't support the Gigabyte GA-Z97N-WIFI onboard Network Controller and SATA Controller. During install you will be stopped on the error "No support network interfaces available".

	== Intel NIC drivers ==
	To be able to install ESXi you need to add "unofficial" drivers to the install ISO. Gigabyte doesn't really mention which specific Intel Network Controller it is used, but it is the Intel I217-V. To add the drivers. To add the drivers to the install ISO use ESXi-customizer to merge the VIB file (drivers) with the official ESXi ISO.
