In this episode, I’m playing with Single Root I/O Virtualization (SR-IOV) in Proxmox Virtual Environment (PVE). I’ve heard ruomors that it will be anything from a minor to major improvement in IO performance for my VMs, so I wanted to do some testing on my own system to be sure. Please don’t take my results as final, I’m not comfortable saying that I’ve removed all of the background tasks and load from the measurements.

In this video, I’m setting up Authelia. It’s a very lightweight authentication service, which can be used to provide authentication to services which don’t natively support any form of authentication. I think this is a great choice for small scale homelab environments, as it’s simple to run and administer. Contents Video Authelia Configuration User File TLS Certificate Protected Service Example with Caddy Video Authelia I installed Authelia on an LXC container (Debian 12), and set it up with a dns name / AAAA record in public dns, and all the jazz required for normal HTTPS access.

This video started as the answer to a simple question - how can I self-host a service for my friends and family, behind cgnat, without requiring them to install any apps (like tunnels)? This video turned into a bunch of different ways to proxy IPv4 to IPv6, so you can receive IPv6 traffic natively and bring in legacy traffic from a VPS which does have public IPv4. While I’m giving you a lot of different examples and methods here, you can mix and match a lot of them to fit your needs.

Today I’m trying to reduce the power consumption of my Proxmox Backup Server. The HP Microserver is great for what I need, but it’s kinda loud and I’m working on optimizing my power bill. The homelab is the largest single consumer of electricity aside from the air conditioning in the summer, so it’s something I’m looking at heavily. Anyway, I thought I could do this purely with systemd sleep / suspend initially.

You’ve probably heard all about creating multiple VLANs, for things like your IoT network, guest wifi, and more. But do you know what a VLAN actually is, and what the difference is between a VLAN and a Subnet? Today I’m going to cover the numbering of subnets in your network, and how to set up new subnet and VLAN interfaces in OPNsense. Come along on this adventure!

In this project, I explore an all-in-one home server using low cost hardware, bringing together as many common home applications as possible in a single box. Terramaster NAS as low-cost Proxmox node? Teardown and SW Install! In the first video, I introduce the hardware for this project - a cheap Terramaster NAS! It combines two HDD bays and two NVMe slots in a very tiny and low power brick, with dual 2.

I’ve been using Mikrotik RouterOS for awhile now, both using their hardware and their virtual image (Cloud Hosted Router). It’s a great product for routing and firewalling, while it’s not a NGFW it’s an absolutely amazing router and their L2/L3 switches are also a great value for the price. So anyway, I often setup images of the latest CHR in Proxmox VE for testing things. I create vmbr bridges in Proxmox to point-to-point link multiple CHRs, and can lab out complex network setups.

When you’re troubleshooting network issues, it’s often extremely helpful to view and analyze packet captures. The de-facto tool for this is the open-source Wireshark, which has an extensive protocol decoding capability. So, as a Proxmox user, it would be nice to be able to analyze VM networking issues using Wireshark. Unfortunately for us, Wireshark is a graphical application and Proxmox’s web UI doesn’t support it. However, we can use the command-line tool tcpdump to create a pcap file, and then analyze that file in Wireshark.

So Linux has adopted Persistent Device Naming, which is a really great thing for most systems. Unlike the old days where we just had eth0 and eth1 and eth2 etc (which at least has no spaces unlike Local Area Connection 6 that another OS uses), whose order depended on driver initialization in the kernel. Most people just had eth0 and were happy, and most people will still just have one Ethernet interface and will still be happy.

Today I’m taking my 10 servers and hopefully working that list down to just 7! JUST SEVEN! So, driven by my desire to consolidate my critical services into one box so I can lab away with the rest of the boxes, I am taking the time to shut down some of the most critical servers in the house and re-home them, then disassemble the parts for the next project. Come along with me on this adventure!
