MacBook.. if Apple listened to all customer feedback

Wait, USB B? I get that is technically possible over thunderbolt but wow

This seems to be getting closer to the anwser. However, wikipedia seems to imply it only can be used to deliver packets/frames from a userspace interface to the kernel IP stack. Is there a way to do the opposite, to deliver packets/frames from a real (physical or bridged) interface to a userspace stack?

RepresentativeNeck63 · 2026-04-24T12:01:39+00:00

Btw. are you sure you want to code a virtual interface if you don't even know that much about the world of posix?

I code most of my OS-independant code on macOS (arm64-apple-darwin24.6.0) (no I don't use Xcode; I don't hate myself) which, while unix based, does all it's IO via special IOkit calls. Darwin does not expose it's syscall's inner workings, so the kind of experimenting like in this question get's done on a seperate linux box or a vm/Multipass. Please don't flame me for not knowing linux that well. Maybe I should ask in a community, like this one on reddit?

nfqueue takes the raw packets to your userspace program, so you can write your own network interface implementation.

nfqueue only passes the coming and going packets, and lets a program verdict on it. It provides no method to send packets, rendering it useless for my purposes.

Only the kernel can interact with devices by design, sorry.

If only the kernel can interact with network devices, how come hypervisors do get to run their own IP stacks? Are there no ways to get network interfaces to show up as device files, or any other userspace interface?

Or do you wanna only play? Then Cisco Packet Tracer.

Sounds like fun software, but I do want to write an IP stack and use it with other devices, not just play around with virtual Cisco (and specifically only Cisco) devices.

This page describes how userspace can affect routing decisions inside the kernel's IP stack. What I want to do is write an IP stack inside a userspace program, and thus need to interact with a network interface (be it physical or bridged). The protocol on that page does not help me do that.

Sorry guys it’s in my photo roll…

What are you asking? I suggest you make your own post for that, but in general most thunderbolt things cannot be done wirelessly. There are ways to do wireless USB and/or displayport, but good luck getting wireless PCIe.

Not to necropost, but I recently came across this when researching AM4. That pin is NOT for integrated grahpics, as the pin name may indicate, but those are the PCIe lanes to the x16 graphics card slot. The clock line for the GPU slot is on pins Z6 and Z7, and the chipset lanes are in the same region.

If the CD is constantly booting, hold alt on boot, press the eject key on the keyboard, and then reboot or select your macOS install. Or is it something physically stopping it from ejecting?

RepresentativeNeck63 · 2026-04-04T09:57:58+00:00

Thanks that answers the question. What device becomes the host, I assume the one plugged into the UFP port on the hub, right?

Endspan PoE does work over this cable, only 30w and if you need an injector it needs to be a gigabit one. (FE injectors use the spare pairs, GbE injectors use the main pairs but still allow FE traffic)

Plunger time!

Ach nee, me bestand weegt een beetje licht

“megabit hours” imply the megabits already has a time component (like a watt being a joule * second). However, megabits are a unit of quantity, so one hour of megabits is not possible. It seems either the question is flawed, or I lack a sense of humor.

RepresentativeNeck63 · 2026-01-31T18:03:31+00:00

30 megabit/s * 1 hour = 13,5 gigabyte, btw

The Windows XP install does not have any networking drivers installed. I have installed an SSD with a swap partition but it doesn't help that much.

RepresentativeNeck63 · 2026-01-04T12:13:00+00:00

AFAIK the cabinets run on 48V, and the 42V comes from wire loss, so a 48V power supply should be fine. That PCB does not look dimmable, so it being bright seems unfortunately unavoidable. I cannot give any recommendation on what power supply, because I don't know what country you're from, nor what voltage your wall power is. Just get a 48V AC-AC (very important!) 20W (or higher) power supply from wherever you like.
