My Dog's Garage Runs OpenBSD

I was inspired by the April 2017 article in undeadly.org about getting OpenBSD running on a Raspberry Pi 3B+. My goal was to use a Raspberry Pi running OpenBSD to monitor the temperature in my garage from my home. My dog has his own little "apartment" inside the garage, so I want to keep an eye on the temperature. (I don't rely on this device. He sleeps inside the house whenever he wants.)

The state of toolchains in NetBSD

While FreeBSD and OpenBSD both switched to using LLVM/Clang as their base system compiler, NetBSD picked a different path and remained with GCC and binutils regardless of the license change to GPLv3. However, it doesn't mean that the NetBSD project endorses this license, and the NetBSD Foundation's has issued a statement about its position on the subject.

Bandwidth limiting on OpenBSD 6.8

I will explain how to limit bandwidth on OpenBSD using its firewall PF (Packet Filter) queuing capability. It is a very powerful feature but it may be hard to understand at first. What is very important to understand is that it's technically not possible to limit the bandwidth of the whole system, because once data is getting on your network interface, it's already there and got by your router, what is possible is to limit the upload rate to cap the download rate.

FreeBSD's ports migration to git and its impact on HardenedBSD

FreeBSD completed their ports migration from subversion to git. Prior to the official switch, we used the read-only mirror FreeBSD had at GitHub[1]. The new repo is at [2]. A cursory glance at the new repo will show that the commit hashes changed. This presents an issue with HardenedBSD's ports tree in our merge-based workflow.

FreeBSD Remote Process Plugin: Final Milestone Achieved

Moritz Systems have been contracted by the FreeBSD Foundation to modernize the LLDB debugger’s support for FreeBSD. We are working on a new plugin utilizing the more modern client-server layout that is already used by Darwin, Linux, NetBSD and (unofficially) OpenBSD. The new plugin is going to gradually replace the legacy one.

Tailscale on OpenBSD

I spent some time setting this up today evening and thought I’d post the steps here. Nothing fancy, just putting together various pieces actually.
I assume you know what Tailscale is; if not check out their website. Basically it is a mesh network built on top of Wireguard. Using it you can have all your devices both within your LAN(s) and outside be on one overlay network as if they are all on the same LAN and can talk to each other. It’s my new favourite thing!

macOS to FreeBSD migration a.k.a why I left macOS

This is not a technical documentation for how I migrated from macOS to FreeBSD. This is a high-level for why I migrated from macOS to FreeBSD.
Not so long ago, I was using macOS as my daily driver. The main reason why I got a macbook was the underlying BSD Unix and the nice graphics it provides. Also, I have an iPhone. But they were also the same reasons for why I left macOS.

Our monitoring of our OpenBSD machines, such as it is (as of November 2020

We have a number of OpenBSD firewalls in service (along with some other OpenBSD servers for things like VPN endpoints), and I was recently asked how we monitor PF and overall network traffic on them. I had to disappoint the person who asked with my answer, because right now we mostly don't (although this is starting to change).

FreeBSD is an amazing operating System

Update 2020-01-21: Since I wrote this article it got posted on Hacker News, Reddit and Lobster, and a few people have emailed me with comments. I have updated the article with comments where I have found it needed. As an important side note I would like to point out that I am not a FreeBSD developer, there may be things going on in the FreeBSD world that I know absolutely nothing about. I am also not glued to the FreeBSD developer mailing lists. I am not a FreeBSD "fanboy". I have been using GNU/Linux a ton more for the past two decades than FreeBSD, mainly due to hardware incompatibility (lacking or buggy drivers), and I love both Debian GNU/Linux and Arch Linux just as much as FreeBSD. However, I am concerned about the development of GNU/Linux as of late. Also this article is not about me trying to make anyone switch from something else to FreeBSD. It's about why I like FreeBSD and that I recommend you try it out if you're into messing with operating systems.

I think the year was late 1999 or mid 2000 when I one day was browsing computer books at my favorite bookshop and I discovered the book The Complete FreeBSD third edition from 1999 by Greg Lehey. With the book came 4 CD Roms with FreeBSD 3.3.

I had already familiarized myself with GNU/Linux in 1998, and I was in the process of migrating every server and desktop operating system away from Microsoft Windows, both at home and at my company, to GNU/Linux, initially Red Hat Linux and then later Debian GNU/Linux, which eventually became my favorite GNU/Linux distribution for many years.

When I first saw The Complete FreeBSD book by Greg Lehey I remember noticing the text on the front page that said, "The Free Version of Berkeley UNIX" and "Rock Solid Stability", and I was immediately intrigued! What was that all about? A free UNIX operating system! And rock solid stability? That sounded amazing.

Hyperbola Dev Interview

In late December 2019, Hyperbola announced that they would be making major changes to their project. They have decided to drop the Linux kernel in favor of forking the OpenBSD kernel. This announcement only came months after Project Trident announced that they were going in the opposite direction (from BSD to Linux).

Hyperbola also plans to replace all software that is not GPL v3 compliant with new versions that are.

To get more insight into the future of their new project, I interviewed Andre, co-founder of Hyperbola.

Improving the ptrace(2) API and preparing for LLVM-10.0

This month I have improved the NetBSD ptrace(2) API, removing one legacy interface with a few flaws and replacing it with two new calls with new features, and removing technical debt.

As LLVM 10.0 is branching now soon (Jan 15th 2020), I worked on proper support of the LLVM features for NetBSD 9.0 (today RC1) and NetBSD HEAD (future 10.0).

The first FreeBSD conference in Australia

FreeBSD has existed as an operating system, project, and foundation for more than twenty years, and its earlier incantations have exited for far longer. The old guard have been developing code, porting software, and writing documentation for longer than I’ve existed. I’ve been using it for more than a decade for personal projects, and professionally for half that time.

While there are many prominent Australian FreeBSD contributors, sysadmins, and users, we’ve always had to venture overseas for conferences. We’re always told Australians are among the most ardent travellers, but I always wondered if we could do a domestic event as well.

And on Tuesday, we did! Deb Goodkin and the FreeBSD Foundation graciously organised and chaired a dedicated FreeBSD miniconf at the long-running linux.conf.au event held each year in a different city in Australia and New Zealand.

A practical guide to containers on FreeNAS for a depraved psychopath

This is a simple write-up to setup Docker on FreeNAS 11 or FreeBSD 11.

But muh jails?

You know that jails are dope and you know that jails are dope, yet no one else knows it. So here we are stuck with docker. Two years ago I would be the last person to recommend using docker, but a whole lot of things has changes past years…

So jails are dead then?

No, jails are still dope, but jails lack tools to manage them. Yes, there are a few tools, but they meant for hard-core FreeBSD users who used to suffering. Docker allows you to run applications without deep knowledge of application you’re running. It will also allow you to run applications that are not ported to FreeBSD.

Why you should migrate everything from Linux to BSD

As an operating system GNU/Linux has become a real mess because of the fragmented nature of the project, the bloatware in the kernel, and because of the jerking around by commercial interests.

Migrating drives and the zpool from one host to another.

Today is the day.

Today I move a zpool from an R710 into an R720. The goal: all services on that zpool start running on the new host.

Fortunately, that zpool is dedicated to jails, more or less. I have done some planning about this, including moving a poudriere on the R710 into a jail.

Now it is almost noon on Saturday, I am sitting in the basement (just outside the server room), and I’m typing this up.

• In this post:

  • FreeBSD 12.0
  • Dell R710 (r710-01)
  • Dell R720 (r720-01)
  • drive caddies from eBay and now I know the difference between SATA and SATAu

OpenBSD in 2019

I’ve used OpenBSD on and off since 2.1. More back then than in the last 10 years or so though, so I thought I’d try it again.

What triggered this was me finding a silly bug in GNU cpio that has existed with a “FIXME” comment since at least 1994. I checked OpenBSD to see if it had a related bug, but as expected no it was just fine.

I don’t quite remember why I stopped using OpenBSD for servers, but I do remember filesystem corruption on “unexpected power disconnections” (even with softdep turned on), which I’ve never really seen on Linux.

That and that fewer things “just worked” than with Linux, which matters more when I installed more random things than I do now. I’ve become a lot more minimalist. Probably due to less spare time. Life is better when you don’t run things like PHP (not that OpenBSD doesn’t support PHP, just an example) or your own email server with various antispam tooling, and other things.

This is all experience from running OpenBSD on a server. On my next laptop I intend to try running OpenBSD on the dektop, and will see if that more ad-hoc environment works well. E.g. will gnuradio work? Lack of other-OS VM support may be a problem.

• Verdict

Ouch, that’s a long list of bad stuff. Still, I like it. I’ll continue to run it, and will make sure my stuff continues working on OpenBSD.

And maybe in a year I’ll have a review of OpenBSD on a laptop.

I hate the X11 ICCCM selection system, and you should too - A Rant

d00d, that document is devilspawn. I've recently spent my nights in pain
implementing the selection mechanism. WHY OH WHY OH WHY? why me? why did I choose to do this? and what sick evil twisted mind wrote this damn spec? I don't know why I'm working with it, I just wanted to make a useful program.

I didn't know what I was getting myself in to. Nobody knows until they try it. And once you start, you're unable to stop. You can't stop, if you stop then you haven't completed it to spec. You can't fail on this, it's just a few pages of text, how can that be so hard? So what if they use Atoms for everything. So what if there's no explicit correlation between the target type of a SelectionNotify event and the type of the property it indicates?

So what if the distinction is ambiguous? So what if the document is littered with such atrocities? It's not the spec's fault, the spec is authoritative. It's obviously YOUR (the implementor's) fault for misunderstanding it. If you didn't misunderstand it, you wouldn't be here complaining about it would you?

HAMMER2 emergency space mode

As anyone who has been running HAMMER1 or HAMMER2 has noticed, snapshots and copy on write and infinite history can eat a lot of disk space, even if the actual file volume isn’t changing much. There’s now an ‘emergency mode‘ for HAMMER2, where disk operations can happen even if there isn’t space for the normal history activity. It’s dangerous, in that the normal protections against data loss if power is cut go away, and snapshots created while in this mode will be mangled. So definitely don’t leave it on!
