Note to myself : Always read readme after package install/update on #OpenBSD !!!

In the #firefox readme "Graphic Acceleration" section : "layers.acceleration.force-enable" knob to true and "gfx.webrender.enabled" knob to true really transformed the experience.

Thanks to Landry Breuil for the very good work.

I installed an #OpenBSD on my spare laptop for fun this morning. As expected I need to fw_update to access the slopnet.

In what kind of god forsaken world am I totally unable to find a single RJ-45 cable in my cable-rich home? I had thousands of them but today, I can't find any...

Boy... I've never had a single successful #BSD install because I always trip on the most ridiculous things... I know that pebkac but come on :(
I'm Unluck, don't touch me

As usual, YMMV. If you do not use archaic setups and do not care about 3D graphic acceleration, you will be content with NetBSD.

Is there a trick to OpenBSD under XCPng? The ISO boots, gets to this, and panics. Maybe some setting I need to check on the VM configuration? #openbsd #xcp_ng

I am assisting an educational podcast project doing the sysadmin for them. Happy that I was able to advocate for #BSD. We went with httpd(8) #OpenBSD for this, because in the end it is just the feed.xml and some MP3/M4A-files. However, #Apple refuses the feed saying httpd does not support byte-ranges. Looking at the change logs, it should be supported since 5.8 (https://www.openbsd.org/plus58.html). And testing all this with curl does return a 206 and provides me with a working chunk of data. What am I missing here? #NetBSD #FreeBSD #smallweb #podcast

One thing I have been pondering about Wayland on #OpenBSD is, did it get the "xenocara treatment"? Does Wayland come with the same level of hardening on OpenBSD or was it not needed? How secure is Wayland by design and does it fit in the OpenBSD ecosystem?

I do not know if #OpenBSD has a CI system for OpenBSD itslelf.

Run your own decentralized social platform on shared hosting or a tiny VPS WITHOUT Redis, PostgreSQL, or complex infrastructure.

What it makes so special to me? It looks awesome, comes with a great admin web interface and does not require a VPS instance where it can also be operated on a cheap shared hosting systems. By the given requirements, it also easily runs on a #RaspberryPI and all kind of systems, including #FreeBSD, #OpenBSD, #Illumos and more!

This all makes it perfect to everyone and even beginners to run their own instance. With relay support (e.g., fedi-relay.gyptazy.com) it even can consume and post content over non-directly connected instances in the #fediworld!

It's a bit of a shame that this fella went to all of that trouble digging through Illumos.

https://youtube.com/v/tUqHsv6JarY?lc=UgwAiVOVkz-sP_j-H7J4AaABAg

#Illumos is one of the few platforms that does not have the <sys/ttydefaults.h> header from 4BSD. It was ironically quite the wrong place to look. The GNU and musl C libraries have the header, as do all of #FreeBSD, #OpenBSD, and #NetBSD.

The problem is that although <sys/ttydefaults.h> has been around since 1983 (1993 in its current form), almost no-one, apart from people like me who write terminal emulators and whatnot and cannot just use cfmakesane(), knows that it is there. It isn't in any manual.

Which leads to things like stty in GNU coreutils going all around the houses to do something simple, too.

The author went the extra mile and had some kind words to write about OpenBSD's OpenRsync as well:

https://michael.stapelberg.ch/posts/2026-05-24-minimal-memory-safe-go-rsync-vulns/#openrsync

Ironically, I saw this not long after closing a Pull Request to submit an OpenRync port to MacPorts: https://github.com/macports/macports-ports/pull/28096

Not that I don't still have an interest in such things, but it seems as if there are some other things going on (if I observed things correctly, it seems as if Apple maybe commissioned Klara Systems to port OpenRsync to macOS (e.g. https://github.com/KlaraSystems/openrsync)? Yet, it didn't seem as if they did so in a very collaborative spirit with the lead developer Kristaps Dzonsons?). Moreover, I didn't want to just leave that dangling when other MacPorts contributors were side-eyeing the PR as being left open for so long.

I've warned my normie friends that I'm fed up with FB Messenger and WhatsApp and that I'm going to self-host an alternative and if they want to keep in touch with me, they have to contact me there... Now I'm left wondering what's more lightweight for my modest budget VPS between #Matrix and #XMPP (probably the latter?) and what might favor a smooth transition later to an #OpenBSD VPS (might switch from Hostinger to OpenBSD Amsterdam, though both seem to rely to some degree on bloody Cloudflare)... probably XMPP?

I'm crying in #OpenBSD 'option DEBUG` pain.

My Sunday challenge: installing #Devuan in place of #OpenBSD on my laptop so I can install #postmarketOS on an old tablet, because for some reason I only have a blue USB port on that laptop (my SFF PC has a whole bunch of USB ports, but none are blue). Let's see how well restoring the backup will work once I reinstall OpenBSD.

I wonder how many years worth of work would it take to create a #NetBSD / #smolBSD based mobile distro after #postmarketOS has done more progress...

Hello #BSDCafe !
I have recently launched a website: https://fionescu.princeps-poesis.xyz/ - Here I posted what may be the only text in Romanian about #OpenBSD that isn't a news announcement or a recent AI slop translation!
Tl;dr: I have celebrated one year since having switched from #Windows to #Linux by... switching from Linux to OpenBSD my daily driver OS. Why? OpenBSD's "proactive security by default" stance is the best for me - and it runs on my somewhat legacy hardware. Most of the essential software I used on Linux is also here, so for most purposes OpenBSD is fine for me.

You know, the vinyl wrap idea even works without removing the rubber first, but it could be icky later. ;)

My 2009-12-23-manufactured Thinkpad X200t (core 2 duo) is slowwwwly becoming vintage, but it's still terribly useful, except for the batteries.

Even Firefox launches quickly in recent versions of #OpenBSD. It barely feels inconvenient, except when attempting to run fancy websites like v86, which fails gloriously. XD

I even have syncthing on it, syncing up a couple dozen gigs of files and maybe 30k files. It does peg the CPU a bit from time to time, but not too bad. I have it set to poll the different directories at different times, rather than trying to keep active tabs on every file, which I think is too much for OpenBSD to handle without really tweaking with sysctl settings.

Installing OpenBSD on the NanoPi R2S plus

Once I figured out which files to write to the SD card for the NanoPi R2S plus and in what order for #netbsd, installing #openbsd was a breeze.

The second 1G network card is working—the very one that #FreeBSD doesn't recognize ;)

The little Acer doesn't (totally) love OpenBSD 7.9:
- fans are always spinning fast and it's hot. I could probably try to fix it, but I have no time at the moment
- it doesn't suspend - and it's critical, for me

I haven't tried other things, except that Mate works perfectly on X and I can use the touchpad. Volume controls work, the brightness controls work. A step ahead from 7.8, but still not perfect.

I'll probably reinstall Void Linux on ZFS.

It's not microcode. It's not modules. It's likely not processor hardware.

https://mastodonapp.uk/@JdeBP/116611581241448030

It's erroring out in the middle of loader code, before the kernel is even running, that is doing little more than calling 8086-mode firmware services (not OpenBSD's I/O system) to read a whole contiguous section of an ELF format file from an UFS partition on disc. It has already read 7 such sections without a hitch, and is failing reading the 8th.

Which is why I suggested objdump, to check that the ELF file is correctly structured.

After all, look at the file size. It has decreased between the working and non-working versions.

Any of my followers interested in running a mail server with #OpenBSD 🐡 and want to help testing?

Working on the setup and documenting it along the way. So curious to learn if someone wants to tag along or test it.

#selfhosting #digitalautonomy #mailserver #email

Thanks to the proper #OpenBSD manpages, I was able to recover the disklabel of a 1TB SSD that I accidentally nuked moments before

This was all my fault - but fortunately was able to get it sorted, fast

1. doas sysupgrade
2. doas syspatch
3. doas pkg_add -u

Review the errata along the way and implement any changes and you're done.

Damn! rcctl disable on OpenBSD removes custom flags associated with the program in question from rc.conf.local? My old backup of that file had sendmail_flags in there that were now missing...

Did that behaviour change at some point? Never noticed that one before.

Guess I'll not use that command anymore when it's a lossy operation in regards to the service configuration.

(Yes, this behaviour is mentioned in the rcctl(8) man page under the "set" option - "When a package daemon is disabled, it is removed from pkg_scripts and its variables are removed if any.")

#OpenBSD

@justine @jeanmimi
I have no experiences for OpenBSD, but does OpenBSD has loadable kernel modules like FreeBSD?
If so, and if you're doing something like loading via /boot/loader.conf on FreeBSD?

In this case, it can cause random breakage.
On FreeBSD, memory area (staging area) that loader allocates for loading kernel, kernel modules and scratch memories are limited (not dynamically allocating by searching and calcurating the size needed before allocating), thus, if there are any too large kernel modules to be loaded by loader exists, it (or anything loaded later) could be truncated, causes undefined behavior.
So, on FreeBSD, loading kernel modules that are NOT essential to boot to single user mode via /boot/loader.conf is strongly discouraged.
Loading kernel modules via kld_list variable in /etc/rc.conf, mean that loaded AFTER loader hands over to kernel, is encouraged whenever possible.

This almost promissingly happen when booted from ZFS and NVIDIA GPU kernel modules and/or DRM/KMS kernel modules for Intel and AMD are specified to be loaded via /boot/loader.conf.
