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.

The subject of this blog is to explain how I've configured my OpenBSD 7.6 and FreeBSD 14.1 to connect to their wifi which only "speak" IPv6 This is not a setup I encountered frequently, and I just want to remember how I did it ;) Fri, 03 Jan 2025 13:36:00 +0100 http://www.vincentdelft.be/post/post_20250103 http://www.vincentdelft.be/post/post_20250103 This is a very spimple idea which avoid that cron job sends too much emails. This script store the hash of the email and, based on that, decide that this is relevant or not.

I'm heavily using this feature in my daily scripts: /etc/daily.local or /etc/weekly.local. This allows me to only see what has changed since previous days. This is really useful for [last](https://man.openbsd.org/last) command, for [dmesg](https://man.openbsd.org/dmesg) or for `/var/logmessages`.

One effective approach for automating this process is to use `entr`, a simple and powerful utility for executing arbitrary commands when files change.
