If you have an Intel CPU, there is a good chance you have a KVM built-in (whether you wanted one or not): Intel AMT. Its reputation was tarnished by Intel's dissimulation and opacity about the technology, and a streak of critical vulnerabilities disclosed in late 2017. I chose to take my chances with it anyway for my homelab server. It is secured with a password, mutual TLS (client has to provide a cert), and restric…

How do you reboot the target machine and stay powered?

I know some ipkvm can interface with the ATX header, but that's usually an extra addon. It also requires have some access to the ATC header during installation.

I have a tiny "NAS" where the mobo is the size of credit card and very difficult to access. The power supply is external. The USB doesn't stay powered when turned off.

I cobbled together a bare NanoKVM running debian, a relay normally closed to interrupt mains power to the target, and a tiny little power supply into a 3D printed case. I have also added a diode so that the ipkvm can also be powered by the target USB for flexibility. Note that the sg200x boots with its pin pulled high with a ~50kΩ resistor (pullup). So you need to pull it down with a 1kΩ resistor. This also renders the system more robust to transient voltages anyways.

Earlier quoted context omitted.

There are really two types of KVMs... classic ones were used by consumers to plug multiple computers into one screen, keyboard, and mouse and flip back and forth between them. Networked KVMs let you remotely access a computer or server. It's like VNC except by physically plugging into the ports. This is useful because it allows you to have remote access to a server when its OS is offline, tweak bios settings, watch i…

Got it! So I could for example plug this into my mac mini at home and reboot it after a power failure or something while traveling?

Yes, exactly. And even do things like inject virtual USB drives so you can reinstall an OS or something

I have an ATEN KVM [1] that gets a solid "it does the job" from me. Occasionally a connected computer won't pick up the K, V, or M, and I'll have to reconnect a few times. I use it to switch between my work laptop and my personal PC, and for this situation 4K is a must have. That, and the choice of HDMI instead of DisplayPort, and things that would keep me from getting a JetKVM. [1]: https://www.aten.com/gb/en/produc…

The GL-iNet Commet X is a 4-port IP KVM. It does 4K, albeit at 30fps. https://nascompares.com/2026/06/26/gl-inet-comet-x-kvm-early...

I have the single port PoE version of the glinet. Its been rock solid so far. I’ve been wanting this 4 port version. But they’re sold out every time I check their site.

> I don't see a reason to trust it any less than closed-hardware, closed-source solutions. I would trust a fully-open-source PIKVM more, however.

Isn't jetKVM software open source? I thought it had a public buildroot fork? Been a while since I checked, maybe something has changed.

I got that, it works very well.

Of course putting it on 3 NAS systems (which I can even SSH into) was definitely overkill.

But as Schlock Mercenary's Seventy Maxims of Maximally Effective Mercenaries says, «There is no "overkill." There is only "open fire" and "reload."»
