Setup a PowerWalker VI 1000 SCL UPS with nut in Debian 10 or Proxmox 7

We won’t call our infrastructure “safe” without running some 🔋’s! This is how I set a PowerWalker VI 1000 SCL UPS from BlueWalker for my homeserver running proxmox. Also I modified the default shutdown procedure and added gotify notifications. Enjoy this post 😊

Tunneling your LAN into your private OpenVPN network

In this post I want to show you my OpenVPN LAN tunneling solution 📶. I wanted to access my homeserver and NAS from outside my LAN. There are many options for this problem. You could setup a dynamic DNS service or write a script to report a changing public ip from your router. But you had to rely on for e.g. your DynDNS provider and.. yeah a public ip reporting script is shitty. Cool stuff you could do? Accessing your NAS, using your piHole to block ads or just remote control local computers and printers.

DIY Proxmox Homeserver

There is a time in life of an sysadmins where he needs to bring all his services, data and projects back home. I was considering to buy a 4-Bay-NAS from Synology or Asustor. But I think I’ve build something better and more flexible for less money. A Synology DS920+ 4-Bay 12TB Bundle with 4X 3TB HDDs costs about 920€. So I set my budget limit to be less than 1000€ for more storage and more compute power. So this is my homeserver-build.

Gotify as notification service

You want to sleep calmly through the night? 😴 For security reasons I wan’t to get notified if something happens on my servers. My way to go is to use gotify instead of using for example the default email/sendmail way. Gotify is a simple, open source, MIT-licensed, docker deployable, push-messaging implementation in golang. It is lightweight, fast, and intuitive. Another great thing is the android app. Also it is free and open source. So you can receive instant gotify messages on android devices as well as on every notebook or desktop computer with a browser like firefox installed on.
