Top 12 best opensource games available on OpenBSD.

This article features the 12 best games (in my opinion) in term of quality and fun available in OpenBSD packages. The list only contains open source games that you can install out of the box. This means that game engines requiring proprietary (or paid) game assets are not part of this list.

What security does a default OpenBSD installation offer?

In this text I will explain what makes OpenBSD secure by default when you install it. Do not take this for a security analysis, but more like a guide to help you understand what is done by OpenBSD to have a secure environment. The purpose of this text is not to compare OpenBSD to others OS but to say what you can honestly expects from OpenBSD.

Missing Cron Email When Restarting smtpd

I have a cron job that renews an SSL certificate from Let's Encrypt, and then restarts the smtpd daemon so that the new certificate is picked up. This all works fine--as proven by both the presence of a new, valid cert on disk, and smtpd successfully restarting--but cron never sends an email with the output of the job. What gives?

Enable multi-factor authentication on OpenBSD

In this article I will explain how to add a bit more security to your OpenBSD system by adding a requirement for user logging into the system, locally or by ssh. I will explain how to setup 2 factor authentication (2FA) using TOTP on OpenBSD.

AAA gaming on OpenBSD with Google Stadia

robert@ updated OpenBSD's chromium port to enable Stadia. This significantly expands what is possible in terms of gaming on OpenBSD. In this video, I provide some game footage from OpenBSD with discussion of performance, pros, cons, and the implications for users with different interests in gaming and OpenBSD.
