Introduction If you’ve ever used a Raspberry Pi, you’ve probably used the raspi-config configuration tool. This text-based user interface (TUI) is great for changing 99% of basic settings on the Raspberry Pi, such as the hostname, WiFi country, locale, memory split, etc… However, if you’re managing a fleet of Raspberry Pi devices, or just really like configuration management tools, you’re probably looking for a way to automate setting these items from the command line....

Introduction My hypervisor since 2017 has been an Intel NUC7i3BNH. It has a 2c/4t 15W laptop CPU (Core i3-7100U), with 2x 16GB Crucial DDR4, and a 512GB Samsung 860 Pro. While it served me well over these years, I’ve outgrown the CPU and cooling solution. The search for a new hypervisor Size, noise, and power As outlined in my homelab mini-rack post, my homelab devices (router, switch, AP, NAS, and hypervisor) all sit on the bottom shelf of the entertainment center in my living room....

Update: 2021-01-10 I made the following changes and updated the post below (not the pictures) to reflect those changes: Replaced side vent panels with metal bars Added labels to patch panel One of the RJ45 couplers was stuck in 100Mbps mode and would not transfer full 1Gbps. I switched it around to a device that only has a 100Mbps NIC (IP camera) Introduction I don’t have space in my house for a full-size 19" server rack (but a man can dream)....

Introduction I have a small homelab in my home that runs pfSense, Proxmox, Docker, a Synology NAS, UniFi wireless, etc… I already monitor my pfSense firewall logs using Graylog, but I was looking for a solution to monitor hardware (e.g., CPU usage, RAM usage, etc…) as well as software processes (e.g., containers using network, current download/upload speed, etc…). I stumbled upon two separate software stacks for this. First is the TICK stack, which is composed of open-source products from InfluxData:...

Introduction With the winter weather, we’ve been having brownouts and power losses more frequently. I wanted to purchase a UPS to protect my equipment from this, but I also wanted to receive alerts when the power goes out, and possibly shutdown equipment. For this, I need an Uninterruptible Power Supply (UPS) and a computer to monitor it with. Hardware As you guessed by now, I’m going to be using my Raspberry Pi to monitor the UPS....
