Warning: Don't browse their documentation site, it's filled with domain-specific jargon like FPS, BIOS, LAN, HDMI and other things, and not a single one is explained first! They should clearly read "Product Websites for Dummies" again.

It's an aposematism. Everything working as intended

Even if not intended, it is a good method of keeping support levels to a reasonable minimum.

>It also solved the issue I had with entering a password on FDE (full disk encryption) systems I've fixed that with secure boot (my own keys, not Microsoft's) and TPM2. From that host I can run a program named Tang, which operates in conjunction with another program named Clevis. On hosts without secure boot such as RPis and other ARM SBCs, Clevis will contact Tang at boot time and decrypt the disk. Incidentally my x…

To me, it is a feature to have a password required at boot to unlock the drive. Relying on TPM for keymatter is convenient but comes with caveats I don't like. I don't personally trust that the boot chain and OS on a modern system are secure enough for this model to be similarly secure to using a passphrase properly. And if I care enough to try to secure something in this way, I definitely care enough to pick somethi…

I am using Tang and Clevis without a TPM on an Orange Pi 5. The key is stored on my Tang server. No TPM required.

It is either on my LAN with that server available, or you will need to enter a key.

It am only trying to prevent casual snooping if it goes missing from my garage though. Anybody more sophisticated can have my garage YouTube browsing history.

I suggest to take a look at the reviews on Amazon.

Could you be more specific? I just skimmed through the reviews on the one I use, seems fine?

I really just wish I had a USB-C KVM I could use with my laptop (or even better: tablet)...

I can't find much, and what I find is a bit bonkers.

I ended up buying a license to Orion, using USB-C→HDMI capture card with a Startech VGA→HDMI converter (which requires USB-A power)... in order to achieve a semi-passable KVM (but, without the K and the M...).

I paired with a USB-A Hub and a keyboard and mouse and it kinda works but it's an incredibly janky setup...

... the fact that many servers still output VGA is baffling.

I have 4 of the old ones in service and they're great. Whenever I need to remotely reboot a server those come in handy just great, no more fear of what I'm going to do if the server doesn't come back online. It also solved the issue I had with entering a password on FDE (full disk encryption) systems. Previously I had to rely on a janky solution with booting into BusyBox so that the system can be accessed remotely an…

Not really related to this, but are there good non-IP KVM's left? I'm in the market for one so we can move two home office desks into 1, but all the ones I find seem kinda shit. Asking for USB-C + 2 hdmi or displayports is apparently unreasonable

The cheap alternative I use is based on a USB switch hub and a monitor that has enough inputs for all of the computers I want to switch between.

The hub is a very simple and inexpensive device that essentially just lets you change USB devices between computers. It has 4 ports for USB devices, and 4 input ports for USB hosts. There is a wired remote control that allows you to switch between the hosts.

The way you turn this into a KVM-like device is by having each host connected to the monitor/s indepentently. In my case, I have only two hosts, and each one is connected via HDMI cable to my single monitor. Each host is set up to detect when the USB hub is connected, and then send a DDC command to switch the monitor input over to itself.

The end user experience is: I press a button on the wired remote, which is mounted on my keyboard tray, and then after a short delay the corresponding computer is on my screen and everything works normally.

On linux, this is trivially accomplished with a udev rule + a script calling ddcutil.

On my work machine, a Mac, I could not find a simple solution that worked reliably on my specific Macbook Pro model that I would recommend, so I had an AI write a custom daemon for this purpose.

The major benefit of this "poor man's KVM" is that you do not need an expensive and finnicky piece of KVM hardware. You do not need to worry about the video chip supporting your setup, or firmware bugs. You buy one cheap, commodity product. The downside is the reliance on the hosts, and on monitor features, and having to set up the functionality manually. In my case, this is the sort of thing I basically just set up and then never touched again, so it was a fine trade-off. If I get new computers, or a new monitor, or I change which porta the computers are attached to, then I have to change the code.

What’s a decent quality IP KVM solution that’s not too expensive? We’re looking to put a dozen of mac minis in a collocation, and currently investigating solutions for remote access.

I've had zero problems with my Gli.Net KVMs

GL-iNet has really nice KVM. Maybe the worst thing is the company name, difficult to write it down correctly.

I have an OG JetKVM and it works solidly but the thing that prevents me from using it is no video pass through. The awkwardness of an ‘invisible’ monitor connected to windows at all times is hard to live with - windows and apps open there and I’m constantly having to pull them back to an another monitor. My next KVM will be pass through for this reason, but the consumer ones seem to top out at 4k30, which is not grea…

The higher-end GL-iNet Comets have passthrough. I have the 5G cellular equipped one connected to my OpenBSD home router so if I lose Internet connectivity at home while I am traveling, I can still debug and do something about it.

Yeah that’s what I have my eye on but 4k@30 is just shy of the full 4k@60 goal.
