Install OpenBSD 7.3 on Proxmox (BIOS/UEFI and Cloud-init).

I thought it was an opportunity to take stock of the different methods of installing OpenBSD on our favorite hypervisor. We will consider different scenarios depending on the types of BIOS available under Proxmox (OVMF, SEABIOS); different OpenBSD installation images; and, finally, we'll talk about the thorny subject of OpenBSD's compatibility with Cloud-init...

Creating an OpenBSD Wireguard VPN Gateway.

A couple of years ago I published a blog post about creating an OpenBSD VPN gateway using OpenVPN. I've recently switched from an OpenVPN-based VPN provider to one that uses Wireguard. As a result I've had to redo my VPN gateway...

Use OpenBSD in web browser.

I have created a service that allows you to use OpenBSD (and other operating systems) in a web browser. The URL to the service is instantworkstation.com. Hope it may be useful to you...

Some OpenBSD features that aren't widely known.

In this blog post, you will learn about some OpenBSD features that can be useful, but not widespread. They often have a niche usage, but it's important to know they exist to prevent you from reinventing the wheel...

Tech Independence

Tech independence is not depending on any particular company or software. The only tools you need are the common open source basics built into any Linux or BSD operating system — free public-domain tools that are not owned by anyone, and can run on any computer.

Learn a few of these basic tools, and you can run your own private server on any computer forever, for the rest of your life. Host your own website and email. Keep your own contacts and calendars synced with your phone. Back up and sync your photos, movies, and music to your own private storage. No more subscriptions needed.

You can ignore all the companies offering “solutions”, even if they are free, because they take away self-reliance. The point is to know how to do it yourself, not to have somebody do it for you. It’s worth a little up-front work, like learning how to drive.

Below are simple step-by-step instructions that work. Instead of drowning you in options, it uses an operating system called OpenBSD...

KISS high-availability with OpenBSD.

My HA solution for Web and Gemini is based on DNS (OpenBSD's nsd) and a simple shell script (OpenBSD's ksh and some little sed and awk and grep). All software used here is part of the OpenBSD base system and no external package needs to be installed - OpenBSD is a complete operating system...

Re: lcamtuf on the recent xz debacle

Just for clarity, does anyone know what "Unix-like operating systems" would be affected by this?

None. TLDR: The build process of the backdoor explicitly aborts on platforms other than Linux x86-64...

OpenBSD Webzine ISSUE #17.

The webzine is almost 10 months late, I got unable to handle the webzine for a while and so I started to accumulate a huge backlog. As time passed, it became more and more daunting to deal with all the content. In order to get out of this situation, here is a special webzine edition with all the links gathered since then, separated in three categories of "difficulty": simple / medium / advanced. It is only an attempt to separate complicated topics from content everyone would enjoy, do not hesitate to take a peek on the three levels :)
