NixOS: Getting Started, Installing Packages, and Configuring the System
0 (0)

5 August 2026

We got a new instance, a hardware server that will run our self-hosted LLMs. The server will run NixOS – not my choice, but the system looks interesting. I’ve been hearing about it for a long time, and now I have a great opportunity to get familiar with it. For now, my part is only… Read More: NixOS: Getting Started, Installing Packages, and Configuring the System0 (0) »

Arch Linux: a DNS Mystery – VPN, systemd-resolved, and Unbound
0 (0)

21 May 2026

I’d been wrestling with the problem of accessing AWS EKS from the office for a long time – finally lost my patience and figured it out 🙂 Here’s the problem: there’s an AWS EKS cluster with both Public and Private endpoints for the API. Working from my office laptop, sometimes requests to it go through… Read More: Arch Linux: a DNS Mystery – VPN, systemd-resolved, and Unbound0… »

8 May 2026

In the post MikroTik: setting up WireGuard and connecting Linux peers I described how to set up MikroTik as a VPN Hub and connect a peer running on Debian Linux. Setup on Arch Linux is mostly the same as on Debian – but every time I end up digging through this blog and my other… Read More: Arch Linux: WireGuard Peer for Connecting to MikroTik0 (0) »

FreeBSD: Jails Networking and Container Management with Bastille
0 (0)

4 May 2026

Sometimes on FreeBSD you need to run services that aren’t officially supported by FreeBSD, and this post actually came about because I was installing Open WebUI on my NAS – and Open WebUI was easier to set up on Linux. So I spun it up in a FreeBSD Linux jail, and to create the container… Read More: FreeBSD: Jails Networking and Container Management with Bastille0 (0) »

Hermes Agent: Running an AI Agent in a FreeBSD Jail with Bastille
0 (0)

3 May 2026

I’ll write about Hermes Agent itself and what it can do separately – today it’s about how to run it on FreeBSD. Yesterday I played around with it on my Arch Linux – now I want a more production setup. I’ll be running it on my NAS with FreeBSD, and obviously only inside a FreeBSD… Read More: Hermes Agent: Running an AI Agent in a FreeBSD Jail… »

30 March 2026

Another installment in the FreeBSD Home NAS series, though this one isn’t really about the NAS – it’s purely about running web services. The full FreeBSD/NAS series starts here – FreeBSD: Home NAS, part 1 – ZFS mirror setup, which now has 15 parts, but FEMP gets its own post. My FreeBSD host already runs… Read More: FreeBSD: Configuring FEMP – NGINX, PHP-FPM, MariaDB0 (0) »

VictoriaMetrics: Basic Monitoring for AWS, Linux, NGINX, and PHP
5 (1)

28 March 2026

The RTFM migration from DigitalOcean to AWS went smoothly, and I’m gradually settling in. New infrastructure, everything new – so for the first while I want to keep a close eye on the server and blog state, which means setting up basic monitoring for WordPress: NGINX, PHP-FPM, the database, and the infrastructure running it all.… Read More: VictoriaMetrics: Basic Monitoring for AWS, Linux, NGINX, and PHP5 (1) »

1 (1)

16 March 2026

Continuing the setup of the new RTFM server. The next step is configuring the ability to send mail from EC2, since both important messages for the root user and RTFM itself need to send emails. I was thinking of using AWS Simple Email Service – purely to refresh my memory on how to work with… Read More: AWS: Amazon Linux – Sending Email with Postfix via Gmail1… »

AWS: Increasing the EBS volume size on an EC2 instance running Linux
0 (0)

16 March 2026

Every time I need to do this, I have to look it up, even though I’ve written about it somewhere before – but it was a long time ago: manually increasing the disk size on an AWS EC2. You get used to Kubernetes, where it’s enough to just change a value in a PersistentVolumeClaim, and… Read More: AWS: Increasing the EBS volume size on an EC2 instance… »
