Where does the OpenBSD source code start?

To clarify the original post below, I mean when I hit the power button on my OpenBSD machine, what exactly happens? What line of code in what file does (I suppose the UEFI app) say to the CPU "okay I want you to start running this thousands-of-files-of-code software package that is OpenBSD here"?

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.

I got the GNU Modula-2 compiler working on OpenBSD.

When it rains it pours. After making a splash with D,1 I remembered that some time ago I began an attempt to bring the GNU Modula-2 compiler to OpenBSD. Because why not? Modula-2 is a language that exists and has compiler implementations. I guess my goal is to bring all the languages and compilers to OpenBSD. And as always, there are lessons to be learned. So let's learn some.

An OpenBSD-focused Ansible playbook embedded in type-annotated Python.

openbsd-run is an Ansible playbook embedded in type-annotated Python which allows for running the Ansible playbooks directly or via command line. The goal is to trivialize deploying and maintaining OpenBSD-based services.

OpenBSD 6.9 Router Benchmarks.

I've been using OpenBSD for my home router/gateway for years, and have run it on a number of different types of hardware. I recently got Verizon's gigabit service which is advertised at up to 940 Mb/s download and 880 Mb/s upload speeds, so I decided to benchmark some of the routers I have laying around. The contestants are:

- Ubiquiti EdgeRouter Lite: dual core 500 Mhz Cavium Octeon, Cavium ethernet using cnmac driver
- PC Engines APU4: quad core 1 GHz AMD GX-412TC Jaguar, Intel i211AT ethernet with em driver
- Ubiquiti EdgeRouter 4: quad core 1 GHz Cavium Octeon, Cavium ethernet with cnmac driver
- Supermicro E300-8D: quad core 2.2 GHz Intel Xeon D-1518 (SMT disabled), Intel I210 ethernet with em driver

Opening a Garage Door Using OpenBSD on a Raspberry Pi.

OpenBSD lets one control the GPIO pins on a Raspberry Pi. Controlling a garage door is simple: connect the GPIO output pin to one side of a relay's coil, connect the 5 volt output of the Pi to the other side of the relay's coil, and connect wires from your garage's wall console to the relay's common and "normally closed" ports. Running the program below opens or closes the door. Since the Pi will be connected to the garage wall console, you'll want to enable sshd. I've named my Pi "garage" and my program "og," so I can open the door remotely with ssh garage /home/sven/bin/og

Rolling Back OpenBSD PF Changes.

If you have ever done something dumb in a firewall config and locked yourself out of a machine, you will appreciate the ability to automatically roll a configuration back to a previous version after a timeout period. This is something that commercial routers and firewall devices from Cisco, Juniper, and others have implemented, though their solutions cover more than just the firewall itself.

OpenBSD Mail Server (3 Part Series).

- Rspamd installation and OpenSMTPD configuration on it on OpenBSD
- Rspamd monitoring with OpenBSD relayd
- DKIM Migration: Rpamd instead of DKIMproxy out on OpenBSD / OpenSMTPD

Filtering spam using Rspamd and OpenSMTPD on OpenBSD.

I recently used Spamassassin to get ride of the spam I started to receive but it proved to be quite useless against some kind of spam so I decided to give rspamd a try and write about it. rspamd can filter spam but also sign outgoing messages with DKIM, I will only care about the anti spam aspect.

My Fanless OpenBSD Desktop.

After the disappointment of my X1 Nano and learning that all future Intel “Evo”-branded laptops would lack S3 suspend, I started thinking about returning to my M1 MacBook full-time or building an OpenBSD desktop. I chose the latter, building my first desktop machine in many years...
