I want to use this anniversary post to look back at everything I've written over the last decade: what has stayed the same, what has evolved, and what I've replaced along the way.

Unfortunately, that's exactly what I need — I want to reach my home server from anywhere. Thanks to WireGuard as set up on OpenBSD, there's a very simple solution to this. This post explains how to do it.

We assume your mail is hosted on a remote IMAP service and you want to filter it locally before your best email client (K-9 Mail in my case) ever rings. This is an intermediary setup where I keep my provider as MX records, but I'm allowed to perform my own spam filtering. Then by using imap server, I can publish cleaned inbox.

Thanks to a continuous check on different log files, I'm able to automatically add bad IPs in the pf firewall (OpenBSD). This blog will explain how I've setup log2table and how I treat those bad IPs Sat, 31 Jan 2026 21:14:00 +0100 http://www.vincentdelft.be/post/post_20260131 http://www.vincentdelft.be/post/post_20260131  Last year I've took notes about the way to connect to FOSDEM's wifi from my laptop doing dual boot OpenBSD and FreeBSD. But this year those commands, were not working. So, here the new method.

Introduced over two decades ago, they provide lightweight, secure isolation for processes and filesystems without the overhead of full virtual machines or the complexity of Linux container setups. What makes them especially appealing today is how straightforward it is to create and destroy them — no bridges, no epair interfaces, no VNET, no NAT rules, no sysctl tweaking, and no permanent rc.conf hacks. In this post, I’ll walk you through the exact process I use to spin up a clean FreeBSD 14.3 jail and then completely remove it, demonstrating just how simple and lightweight the whole thing is.

This guide describes a clean, automated setup for streaming high-quality music from a FreeBSD-based NAS to an OpenBSD machine connected to a hi-fi DAC over optical fiber (S/PDIF). The solution uses **Music Player Daemon (MPD)** on the FreeBSD NAS as the music server and **sndio** for low-latency, high-fidelity remote audio output to the OpenBSD client. The setup ensures that turning on the amplifier and DAC automatically prepares the OpenBSD audio system and starts playback on the NAS — all without manual intervention.

I've been there—furious, fumbling for my phone's hotspot like it's 2015. But no more. I just wired up a sneaky 4G sidekick: the TP-Link MR600. It's like a ninja router—silent, speedy, and ready to swoop in when your ISP flakes out. One ping fails? Boom. Traffic flips to cellular backup in seconds. No drama, no downtime. All powered by some clever OpenBSD magic that makes it feel effortless.

Thus, I've decided to build mine and to share it with you. Feel free to copy / re-use part of it.
