Quick tip, if you want to start fresh on your self hosted Unifi Controller instance, there is a simple command to just purge and reset the database and settings to factory defaults. Just ssh into your Unifi Controller instance on Ubuntu or Debian and enter as superuser: No need to apt uninstall anything or do […]
Ubiquiti just released its new network controller version 7.3.76 and alongside with the major change of jumping from Java 8 to Java 11, the update had a lot of features and changes under the hood added. Unfortunately Ubiquiti did not release the new controller version via the official apt repositories. In the official patch notes […]
I was looking for a secure and reliable way to expose some of my homelab webinterfaces and APIs to the public. I decided to go for a Cloudflare Tunnel, so I don't need to open any port like 443 on my firewall and use Authelia and OpenID as an identity provider to securely authenticate and […]
If you are running multiple devices in a cluster layout, like docker swarm or kubernetes, you may have multiple IPs that could lead to the same service. And to make things easier you probably have set a local DNS record within your piHole to give the service an easier local domain name instead of remembering […]
Update hint: This guide installs via the official apt debian/ubuntu repositories, which does NOT have yet the actual controller version 7.3.76 including Java 11. If you want this new version, please follow after this install my update guide to the latest version here. With the latest release of Ubiquitis' Unifi consoles, the UXG-Pro, I am […]
In this quick guide we are going to setup the scalable GlusterFS filesystem for a four node Docker Swarm cluster on Ubuntu 20.04 LTS. More precise: we replace an existing persistent NFS storage on the cluster with the new GlusterFS and make it available under the same old mount point as the old NFS. Therefore […]
Most owners of a Unifi Dream Machine (Pro) know about the automatic backup feature Ubiquti offers in their UDM(P) interface. The feature creates automatic backups of all your config settings and stores it locally on the device. So you can manually download it from there before you change something. But what if you forgot about […]
WireGuard is quite a hyped new VPN server that has some pros why you would like to use it. Its part of the Linux kernel now and therefore you can setup a WireGuard VPN server on almost every piece of hardware. But some people might want to run it on their router, and if you […]
Every SmartHome enthusiast loves Home Assistant. And so do I! But, with Home Assistant as your central brain and heart of your SmartHome, downtimes are nothing you want to have or run into. So I thought a lot about what would be the best, yet affordable, hardware setup to make Home Assistant as reliable as […]

This guide will show you how to easily virtualize the new Windows 11 on Proxmox 7 including TPM 2.0. 1. Download the ISOs: We need two ISO files: Windows 11: Go to Microsoft and download the official Windows 11 Installer ISO. virtIO drivers: Go to virtIO GitHub and download the latest ISO version there Once […]
I decided to run all of my supporting homelab services in a more flexible setup, making it easy to deploy and test new features, while also ensuring that already running and needed tasks are stable and constant available. Therefore I decided to create a four node Docker Swarm cluster with four Raspberry Pis 4 8GB […]
In this guide we will cover how to create a High Availability pihole setup with Gravity Sync, so next time one of your pihole is not reachable, your DNS requests are still resolving over the fallback pihole instance. Lets get started! Getting started: setup a second machine First, either create a second virtual machine if […]
This is a quick tutorial about a case I recently encountered. After a upgrade of a clients Proxmox cluster to the latest version, two very important VMs were not able to power on again. As it turned out fixing the root of the issue would take much longer than the downtime would allow for, as […]
Its very important to keep the order of this guide and not add and setup things prior or later, as this will create errors. Also I tried to keep it as detailed as possible, therefore it is going to be a fairly long article. Use this index to quickly jump to the area you need: […]
In this tutorial we are creating a Proxmox cluster with two physical servers, node1 and node2, and we will add a RaspberryPi as a third Quorum device to make the Proxmox cluster working as intended in High Availability mode with having an odd number of cluster votes. This gives smaller business or a homelab user […]
Problem to solve: If you have a Proxmox Server and you like tinkering around with it like I do, then you probably know that feeling that all of a sudden nothing seems to be working as it used to be and you want to re-roll to a certain point and just start all over again. […]
This project was already build in 2015, but due to a recent reinstall of the MagicMirror software on my mirror, I decided to share the whole build including the up to date software setup process from scratch. Also I can tell that it ran flawless for the past 5 years now, so pretty stable 🙂 […]
Today we install the famous DNS advertisment blocker pihole in a LXC container on a Proxmox server, and set this as our network wide primary DNS server on the Unifi controller. The cool thing is that even as pihole was born as a Raspberry Pi project, it can easily run on most other Debian-based operating […]
From time to time you may want to quickly copy a raspberry pi image from one system to another....but only have a smaller SD card. Or you started your project as a tryout on a crazy 64GB sd card, and realize later that 8GB would be way enough. So what you want to do, is […]
We all know this situation: you are on a fresh setup of Linux remote server or a headleas Raspberry Pi, and somehow the speed is not feeling right. Besides a iperf LAN speedtest for your device you can quickly check your connection speed to the outside with this handy python script command: If you don’t […]
This quick guide shows my standard routine for setting up secure SSH on new fresh installs of Raspbian or Ubuntu VMs. First if you are still using any system default user like "pi" or "root" or "admin", change this and create your own, custom user. Lets start in this example with our new user name […]
I exchanged my Synology server for a 10Gbit capable model, and after deploying it, I wanted to confirm the actual available speed over my network. For this matter I use the tool iperf3. It is a great command line interface (CLI) based tool, that supports all varieties of operating systems: from Windows over MacOS and […]

This is how to turn a Raspberry Pi into a powerful VPN box, that automatically connects to a VPN on boot and keeps itself connected by trying to reconnect when disconnected. If it gets disconnected from the VPN at one point we are ensuring that all traffic gets drop until we are back connected with […]
