Built a nice little PiKVM and deployed it in my NAS. The NAS is heavy and placed in a dark half-height place under the stairs so it’s awkward when things go wrong and you need hardware access.
For those that don’t know what PiKVM is: https://pikvm.org/
It’s not a graphics card. https://pikvm.org/
So what does it do?
For me a KVM is a switch for keeb, mouse and eventually a screen (or a virtual machine :-)
It’s a KVM in the same sense but instead of switching it provides the functionality over a web interface so that I can manage my server from my workstation or laptop instead of crawling in the space beneath the stairs where my server is if something goes wrong. Compare with IPMI.
