re-enable WOL for atheros (alx) driver

Use the script from here.

automatic dkms module installer for patched alx

This is a quick and dirty setup that will automatically setup the dkms module for your specific kernel version.
This will only work on debian/ubuntu and other derivates and requires dkms and patch to be setup already.

The setup uses sudo and thus you are asked for your password once.
It will then attempt to download your kernels source, copy and patch the alx related files and place a "alx-" in your /usr/src directory, enable and compile the module and finally rebuild your initrd.
Currently the the very first compilation somehow fails, thats why it's run twice.

Notes on setting up OpenVPN on Edgerouter Lite

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).
    1. Client(s) - the device(s) you will be connecting from.
    1. CA Server - used to generate and sign certificates for server and clients to use.

Notes on how to setup full disk encryption on an already setup Raspbian system

Setup full disk encryption using LVM on LUKS (single drive) with remote SSH for an already setup/running Raspbian stretch system. Using this guide there is no need to connect a screen or keyboard to the rpi at any stage since we will setup remote SSH at the same time (at present no other guides available tell you that this is possible).

1. Backup SD card

To be safe, backup SD card (using another computer is easiest in my case): sudo dd bs=4M if=/dev/<rpi_sdcard> | gzip > rpibackup.img.gz or use my fish shell function.

2. Install LUKS dependencies and reboot

                Using acme.sh script to renew LetsEncrypt certs using non-standard SSL port
              
          

        

      

        

  

      

    
1. Install acme.sh shell script


git clone https://github.com/Neilpang/acme.sh.git
cd acme.sh
./acme.sh --install


Optionally, set the home dir and/or account info (if already have one).

If was previously using LetsEncrypt's certbot, can probably get account info from
/etc/letsencrypt/accounts/acme-v01.api.letsencrypt.org/directory/*/regr.json.

Using pyenv seems to be the easiest way apart from a random PPA or finding/downloading/compilign the source myself.


Build dependencies:


sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev



Install Pyenv (as the user who will use it, not root):
