Fix for Proxmox container failing to start after dist-upgrade
  • Upgraded from Ubuntu 16.04 LTS to 18.04 (pre-release) using dist-upgade
  • Upon restart CT would not start
  • Error displayed in Web GUI: command 'systemctl start pve-container@101' failed: exit code 1
  • SSHd in and manually ran CT with pct start 101:
>root@server:~# pct start 101
Job for pve-container@101.service failed because the control process exited with error code.
See "systemctl status pve-container@101.service" and "journalctl -xe" for details.
command 'systemctl start pve-container@101' failed: exit code 1

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.

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 how I setup HTPC for future reference

1. Preparation / OS Install

  • Create liveusb using Ubuntu mini.iso dd bs=4M if=/home/user/Downloads/mini.iso of=/dev/sdf status=progress; and sync in fish shell

  • During install will be prompted for what to install: choose xubuntu minimal and openssh server

  • This time left just one disk (8TB) in the case, and used LVM when partitioning: root given 15gb, data partition given the rest (set recovery-blocks to 1% and inode to largest size since this is just a media partition)

2. Creating a user with limited privileges for Kodi
