Here are some things that one can add to the analysis of the MacOS TCP timeout clock freeze bug.

The code for calculate_tcp_clock() in XNU was changed in May 2025. Older versions of this function (e.g. in xnu-11417) worked quite differently and wouldn't have stopped ticking the clock at 32-bit unsigned integer wraparound.

None of #NetBSD, #FreeBSD, nor #OpenBSD share this exact way of doing TCP timeout processing with #XNU.

FreeBSD does not have a tcp_now and works off the global 32-bit ticks variable. OpenBSD effectively works off the kernel's system clock, too, but with a randomized offset, and does 64-bit unsigned modular arithmetic. NetBSD uses a distinct 32-bit unsigned tcp_now counter that it simply increments by 1 at regular intervals, and does modular arithmetic subtraction.

What is considered state of the art for Endpoint management, and specifically security controls (EDR, SIEM, RMM, etc.) for BSD? There usually exists clients and agents for Linux in this space. There is an abandoned(?) Wazuh port for FreeBSD.

Essentially how does one manage and monitor the security of 100’s or 1,000’s of BSD endpoints like a Windows or Linux or even Mac environment would?

｢ The system stays fully NetBSD-native: isolation and policy enforcement are built into the kernel security framework, not delegated to a separate runtime layer.
The goal is not to replicate Linux-style container ecosystems, but to provide a focused operating model with minimal dependencies, no external control services, and explicit operational boundaries ｣

Can anyone recommend a decent 2 port PCI network card?

Not PCIe or PCI-X!!!!

Bonus if its compatible with #NetBSD and has 1Gb ports

I think this is in #netbsd too from looking at the src. Cannot find it in #freebsd

The new way of selling 'AI' seems to be to push it as a bugfinder. The latest example being waved around as of yesterday includes, as one of its non-embargoed examples, what is patched by this #OpenBSD patch.

https://ftp.openbsd.org/pub/OpenBSD/patches/7.8/common/025_sack.patch.sig

The problematic thing is that this sort of bugfixing hasn't changed the commentary in the code, which stated that p points to the last linked list entry at the point of the added null check and can never be null. But it actually can be, if there was a sole linked list entry that ended up being fully encompassed and thus deleted.

So this kind of 'AI' use is going to give us a lot more comments-do-not-match-code maintenance headaches down the road.

(Both #NetBSD and #FreeBSD factor this out into a separate tcp_sack.c and do the linked list handling slightly differently without a 'previous' pointer.)

🚩 #NetBSD 11.0 Nears Release With RC3 Released For Testing - Phoronix https://www.phoronix.com/news/NetBSD-11.0-RC3

Which has the best source code?

----

Best is whatever you care about about code quality. For some it might be design coherence, for others it might be resistance to security exploits, for others it might be architecture portability.

• #OpenBSD 7.8

#RunBSD

Small fix, big impact 🔧

Initial situation: The network card in my parents’ mini server (NUC5PHY, RealTek 8168/8111) wasn’t properly entering Wake-on-LAN mode during shutdown. The server powers down automatically after inactivity and is woken up on demand via cron (every 1 min) from their laptops. Without WoL, it just stays off → manual power-on required.

Solution: A patch for the NetBSD PCI network driver to hook it into the power management framework. On shutdown, the NIC is now correctly configured for WoL.

First tests: works as expected ✅

Screenshot of NetBSD X desktop using the default CTWM window manager. Hot-Babe (lightly clad; the CPU is running hot) in the lower-left corner, next to conky system monitor. Lower right corner has small terminal windows tailing the snac log and showing 'pfetch' output, respectively; both next to the virtual-desktop switcher in CTWM. Two main terminal windows: One running mrxvt showing 'lspci' output, another running irssi. Plain blue background.

#NetBSD 11.0 RC3 was tagged and will soon be shipped to a http or ftp server near you.

The decision was made to delay the release and make another RC because of a number of important fixes being pulled up. This included ZFS and swap reliability fixes, improvements to support for allwinner risc-v hardware, and a curses compatibility fix.

Scratch that last post about needing a #NetBSD VPS. Remembering ive got good internet these days; and found a NUC w/ enough ram on ebay for a good price.

Dear #NetBSD users what VPS service do you recommend ? I have spun up NetBSD on tunnelr.com before, but sometime after they switched management and names a few years back that dropped NetBSD images.

Something I've been most surprised by while trying NetBSD is how much thought has been put into creating a high-quality TTY experience.

On Linux, trying to create a functional TTY work environment feels like a a hack. Things often didn't work right or require lots of tinkering.

Here, everything just works. Straight out of the installer, I have 256 colour support, audio functionality, and the brightness/volume control keys just... work. No configuration. It's fantastic

Okay, folks, gather 'round, because you are not going to believe this one. My friend who is working at NASA told me this confidential news , but i can finally spill the beans: NASA is officially running NetBSD.

Yeah, you heard that right. Turns out, when you need an OS that can literally run on a potato *and* survive the vacuum of space without a hiccup, you do not mess around. They have been working under wraps with their deep space division on something they are calling "AstroBSD."

Apparently, the Perseverance rover on Mars? Yeah, it is not just taking pretty pictures; it is crunching data with a custom NetBSD kernel.

This just proves what foundation has been saying forever: "Of course it runs NetBSD!" From your ancient router to a rover on another planet.

I likewise was going to point out 'Of course it runs #NetBSD.'.

Modern #FreeBSD has dropped 32-bit support and various older non-IA processors such as PowerPC, so is not the best fit for repurposed old machines.

@codemonkeymike

Greetings BSD Cafe', I have been playing around with the NetBSD packet filter. Based on my understanding, I presume the following would pass as a basic filter for a stand alone host firewall. Its not clean but perhaps adequate enough?

$ext_if = { inet4(wm0) } # LAN Connection

group "external" on $ext_if {
pass stateful out final all
block all
}

group default {
pass final on lo0 all
block all
}

Ok, #NetBSD on Odroid M1S update: I'm setting this one down for a bit. I'm stumped by the ethernet phy and tired beating my head against it. I put in a PR for my current progress, and that's merged into the main repo. Spinning a release might be difficult (for submodule bitrot reasons), so I made a status post with release binaries: https://overeducated-redneck.net/blurgh/netbsd-on-odroid-m1s.html

I'm just going to use a USB-to-ethernet adapter for now and use the board for its intended purpose. Finally.

@mook Well, in this case, I have a #NetBSD image (armv7.img.gz) that I would really like to write onto there.
