Moin, du da draußen. Heute zerlegen wir #PowerDNS auf #Ubuntu 24.04. Kein Marketing-Gerede, nur der Weg, wie ich ihn selbst in meinem #Homelab gegangen bin. Bei mir managt dat Reverse-DNS für alle VMs im #Proxmox Cluster – sauber, schnell und ohne dass ein externer Dienst mitliest.

Hey Fedi, Roast My #homelab

A rather busy looking homelab with various server, RF equipment, phone, a network switch and more

A rather busy looking homelab with various server, RF equipment, phone, a network switch and more. A calendar is seen above.

Alt...

A bundle of wires, (bad cable management) along with a server plugged into a network card, usb, and serial ports.

Entering a new era of #homelab , so sharing my build before I get my server rack built:
Intel Nuc for #Proxmox (#adguard, #alpine VM, game servers)
#dell optiplex-something for my home's #jellyfin using docker
#netgear (dumb) switch because my router doesn't have a lot of Ethernet ports (and for future expansion)
The goal was as budget as possible, this whole setup was less than $100!

Running Podman in production for years now, and I don't miss the Docker daemon one bit.

I just published a deep dive on managing OCI containers the Unix way: daemonless, rootless, and natively integrated with systemd via Quadlets.

I cover:
- Real secrets management
- Auto-updates via systemd timers
- The Docker compatibility layer

This is the guide I wish I had when making the switch.

Small fix, big impact 🔧

Initial situation: The network card in my parents’ mini server (NUC5PHY, RealTek 8168/8111) wasn’t properly entering Wake-on-LAN mode during shutdown. The server powers down automatically after inactivity and is woken up on demand via cron (every 1 min) from their laptops. Without WoL, it just stays off → manual power-on required.

Solution: A patch for the NetBSD PCI network driver to hook it into the power management framework. On shutdown, the NIC is now correctly configured for WoL.

First tests: works as expected ✅

Okay, I just ran into a similar issue which re-prioritized it higher for me to implement... But hey, here it is! You can now also use ACME with any other ACME compatible CAs rather than just Let's Encrypt. In this example, you can see it with my own Certificate Authority (CA) "gyptazy open-source solutions", which is operated by StepCA.

I'm really happy to see how PegaProx becomes better and better every day... Over Easter, several new cool features took place!

What are your favourite but maybe not so well known #HomeLab apps or gadgets?

@monotux Caddy sounds handy thanks. Netbox is also new to me. Do you have a complex setup? I only have one box just now but will add more over time, planning to use #Proxmox to manage VMs. I'll probably start with the backup server and run #HomeAssistant, then build from there.

I'm guessing #Netbox will be overkill for a small #HomeLab even as it grows. What do you think?

#GlitchySocial #Mastodon instance has 5 users now, including me. Only one of them never logged in after registration. It took a blink of an eye to transfer from “hey, I should try to #selfhost a Mastodon instance” to “hey, I’m a service provider now”. Can’t say I’ve got much power but responsibility for sure.

Mein #diday in diesem Monat ist ein wenig nerdi. Ich in meinem Netzwerk einen eigenen #DNS Resolver einzusetzen. #PiHole läuft bereits seit Jahren zuverlässig auf meinem #Proxmox und soll nun mit #Unbound ergänzt werden. Meine derzeitige Frage ist strategisch. Den PiHole #Container erweitern oder Unbound in einem eigenen Container aufsetzen? Wie schauen die Entscheidungen im #Fediverse zu diese Frage aus? #homelab #server #linux

Made a video about recent OSS supply chain attacks. Found a security gap in my own setup while making it. Nobody's immune to this stuff.

I'm happy to share, that I finally had the rime, to install the Nvidia Tesla P4, I got back in October into my homelab and my Jellyfin instance has hardware acceleration 🥳!

For real, many people asked me for their smaller and mid-sized environments, how to handle remote syslog of their nodes. I had some ideas (some of you may have already found my Rust interpretation of this) but I think having this included in #PegaProx as a centralized management interface makes more sense.

So, PegaProx comes with an own syslog server (ipv4/ipv6, udp/tcp, encrypted/unencrypted support) and is wired to the interface within the resources tab. Providing a quick overview of all your logs and filter options. The next thing is wiring it to the notification system of PegaProx, allowing automated alerting. Might be nice to quickly identify when the quorum got lost - all built-in into PegaProx!

How I enhanced my homelab to get connected on the go, without using any other software than wireguard and acme.sh.

This guide walks you through obtaining a wildcard SSL certificate from Let's Encrypt using acme.sh and Cloudflare as the DNS provider.

Replication tasks on my #Proxmox cluster are failing randomly due to timeouts. Hourly tasks can fail once a day. I’m too much in a #friday to investigate. Backups still work and there is no visible fire coming from the #homelab, so let it be.

It’s about ensuring that a failure in one part of the lab doesn’t break the internet for the whole house.

Nerderei der letzten Woche: #immich

Ich war auf der Suche nach einem Foto, was ich mal in den letzten 10 Jahren mit dem Handy geschossen hatte. Bisher habe ich alle Fotos ordentlich quartalsweise auf dem Gerät und dem NAS, sowie in der Cloud abgelegt und alles immer im Zugriff, aber ohne Chance dieses eine Foto schnell unter tausenden zu finden. Ich hatte zuviel Zeit und die #linux VM mit #docker war schnell aufgesetzt.
Fazit: Ich bin total begeistert was das Tool alles kann. Nichts überlebenswichtiges, aber an den Geo Informationen und der Timeline habe ich ja echt Spaß. Das hat mir noch mal einen ganz neuen Blick in die Fotosammlung beschert. Darf nun weiter laufen und das #homelab hat eine #vm mehr, die gepflegt werden möchte...

Ok, well, so much for shrinking my #homelab. Turns out the fans in my #NAS used about 10W... which is insane for that little thing. Getting some new quiet Noctua fans soon.
Besides, the mini-PC is not the best match as I have found.
Oh well, 10W saved currently and the i7 system is back on track.
Can I call that a win? 😂

#homelab stories

I’m #SelfHosting my Photos (#Immich) and Video collection (#Jellyfin).

Now I’m thinking about self-hosting a notes app to replace Apple Notes/Google Keep.

Any recommendations?

#HomeLab

I was tempted to make some changes in my #homelab while I’m away, but the smart part of me made it clear I shouldn’t touch shit until I’m back home. Everything is working fine, I’m just inviting chaos

Was gonna go buy some ethernet cables tomorrow to set up my vm lab, fortunately i looked in my back room and found a pile of Cat5 cables just laying there.

These hypervisors are old SFF boxes with no WiFi support so cables are a must. They are actually pretty decent for a #homelab, i threw in 512 GB SSDs and upped them to 16 GB ram, so now they can both run a couple of VMs without problems using #proxmox.

I think I'm gonna downsize the #homelab a little. Currently sporting a I7 8700 cpu which seems overkill for the three virtual machines I need.

I've got a Ryzen Mini-PC here which would handle that load with no issues.

Back to the drawing board I guess...

A homelab truly is never finished 😀

Ok. What's a cheap linux sbc that has ethernet and a USB port? I don't even really care about performance, it's not going to be doing much. It just needs to have ethernet and a USB port.

Also cheap. Because I'm going to be buying three of them.
