Nornir - Tutorial

https://nornir.readthedocs.io/en/stable/index.html

1 - Initialise a Nornir Object.

  r = InitNornir(config_file='config.yaml')
  nr = InitNornir(config_file='config.yaml', core={'num_workers': 1})		# Useful for testing as it works in serial, doesn't paralellise connections.

2 - Filtering Objects - Can be cumulative.

My notes on how I setup OpenVPN server on Edgerouter Lite. Based mostly on this guide from openVPN wiki. This guide assumes easyrsa3 is being used, otherwise substitute whatever the easyrsa2 versions are for the commands below.

This guide will use 3 different machines.

A Public Key Infrastructure (PKI) will be created on each machine:

• 1. Server - openVPN server (Edgerouter in this case).
• 2. Client(s) - the device(s) you will be connecting from.
• 3. CA Server - used to generate and sign certificates for server and clients to use.
