I have to preface this to say that it's not my main OS, so I have limited time with it. For example here's my total usage per OS per year:

2023:
Linux: 49 d, 14 h, 57 min

2024:
Linux: 191 d, 18 h, 55 min
OpenBSD: 4 d, 7 h, 59 min

2025:
Linux: 175 d, 1 h, 41 min
FreeBSD: 23 d, 17 h, 54 min
OpenBSD: 3 d, 8 h, 19 min

(actually most of the time labeled "FreeBSD" for 2025 was actually Linux. I only converted that one box to #FreeBSD in November)

That said, notwithstanding how "primitive" #OpenBSD's FFS is, I have yet to lose any data with it, even taking into account a basically ornamental battery 😆 and occasional kernel crashes from me mucking about with buggy sysctls.

All that to say, I wouldn't doubt that ext4 is actually more robust than btrfs, even though it's more "basic."

Iconic Minion alarm is the internet's favorite way to signal chaos, urgency, or a major announcement. It has the text: Bee-doh! Bee-doh! Bee-doh!

@willb Had to add the vCard MIME type to #openbsd httpd server. And it works now on iOS with Safari but not as smoothly with Firefox. Which is all part of Apple’s lock-in strategy.

There doesn't seem to be an #OpenBSD pkg or port for that, unless I'm somehow getting the name wrong.

#OpenBSD & #vi / #nvi peeps,

Can someone help me figure out the difference between these two packages? Is there anything I'd need from the iconv variant in normal (monoglot) use?

nvi-2.2.2-iconv
nvi-2.2.2

P.S., Looks like regular nvi-2.2.2 handles UTF-8 just great! :)

I love #OpenBSD (and all the BSDs, heck all the #FOSS OSes, they're all amazing), but y'all, this is a bit sad:

$ time pkg_info -Q nim
animorph-0.3p5

I know about pkg_locate, and I use it by default, honestly, but "that's not in base!" ;)

My network speed is a bit slow, but not that slow.

IIRC, #nim wasn't available for #OpenBSD before? Or was I just dreaming that? XD

Hrm, first real problem with #OpenBSD 7.9: the igc driver seems to hang the output under load :(

I have output errors each time the load goes up which eventually clear.

igc0 at pci1 dev 0 function 0 "Intel I226-V" rev 0x04, msix, 4 queues, address 64:62:66:xx:ww:zz

it is a 4-port box so up to igc3.

The PHY is 2.5G and I noticed it is worse when connected to a 1G switch whereas it is minimal when connected to a 2.5G-capable (10G) switch.

Could this be 64-bit DMA being enabled in 7.9?

Port knocking is mostly a bad idea. But people keep wanting to do it, for some false sense of security. If you don’t consider it a security control but a way to keep garbage out of your logs, it might be valid. In my case I’m using an old USG Pro 4 running OpenBSD as my firewall and I’d prefer to avoid writing stuff to the logs, as I’d prefer the flash not to wear out sooner than needed, definitely not thanks to background radiation on the internet.

Roughly monthly #OpenBSD/luna88k snapshot is updated. It is based on Jun-9 tree.

@nixCraft Already done it. Firewall is #OpenBSD.

Been sinking my teeth over the last few days into #OpenBSD #VMM. Quite a bit unstable - maybe I'm allocating too little RAM or it's Xephyr putting too much stress?

Arch has #OpenBSD #nc twice in the AUR. One package applies all of the Debian patches. One does not.

But they won't have noticed this difference, since they added these to the AUR around the time that Debian stopped patching the if test.

https://aur.archlinux.org/packages/openbsd-netcat-tls

https://aur.archlinux.org/packages/openbsd-netcat-git

#NetBSD, #FreeBSD, and #DragonFlyBSD all use the Jackson netcat.c with the if statement as in the original, so their ncs will all do this too.

Silly question of the #NetBSD folk… I know some of the BSD kernels (notably #FreeBSD, and once upon a time, #OpenBSD) were capable of Linux syscall emulation, meaning they could run Linux applications.

Is this still the case, and if so, does it extend to containerisation like #Docker? Platforms of interest would be `x86-64` and `aarch64`.

https://kb.shells.com/tutorials/NetBSD/Docker/ seems to suggest it was at least at one point, a thing, but the link to the Docker download site is a 404.

OpenBSD’s sppp_pap_input function used attacker-controlled length fields as the bcmp comparison length for credential validation. Sending zero-length name and password fields caused bcmp to return 0 unconditionally, bypassing PAP authentication entirely. The vulnerability was introduced in 1999 and survived for 27 years before being fixed.
