Running Minecraft server on OpenBSD.

For one reason or another, I had to set up a Minecraft server and, given that there is no OpenBSD port, I had to set it up from scratch... BTW, creating an OpenBSD port is out of this post's scope.

How to host your server with OpenBSD?

You are about to dive into the world of self-hosting. This document is written to help you host at home or on a dedicated (rented) server some services unfortunately too often entrusted to third parties. The main goal is to keep things as simple as possible while learning gradually. Of course, compromises have been made. If you feel you want to learn more after reading this, that's great! 😊

Building a Large-Scale Threat Intelligence System with OpenBSD.

In this talk I describe a threat intelligence system that leverages thousands of OpenBSD firewalls deployed at businesses across a wide range of industries. The data is collected, processed, and analyzed to create tactical threat intelligence feeds that are then automatically disseminated back to all the firewalls to defend against Internet threats. The talk discusses why OpenBSD was selected as the platform of choice and how its features are used to achieve the objectives of this system, as well as challenges and lessons learned.

OpenBSD on a Lenovo Thinkpad X220.

This is going to be yet another post about installing / running OpenBSD on an old Thinkpad X220. It’s not going to be different than all of the other guides that are already out there, but my motivation and what came of it afterwards might be interesting for some folks.

OpenBSD: Manage DNS, DNSSEC (to automate TLSA records).

My DNS service run since 4 years, under OpenBSD native tool named nsd. I manage DNSSEC with ldns tools, a package into ports.
