How to remotely reboot a Linux host if SSH fails to connect? - Lemmy NZ

I’ve got a HP ProDesk G3 which I’m using as home server, I’ve installed Ubuntu on it. Earlier this week the services I host on it stopped (Immich & Frigate). I tried to SSH, but it just hung after asking for a password. I could ping it, but it was just unresponsive. I had to force reboot it manually. This is fine, but I’m not always at home. The chip has Intel vPro as far as I know, which could be an option, but I have no idea how this works. The documentation on the Intel site seems focused on enterprises. I tried to connect with RealVNC which does not work, so I think I’ve got to install/configure something on the server first. I also asked Bing Chat but it came up with non existing packages & commands. Welcome your thoughts! /edit: I just found this, which seems to be exactly what I need: https://manpages.ubuntu.com/manpages/focal/en/man7/amt-howto.7.html [https://manpages.ubuntu.com/manpages/focal/en/man7/amt-howto.7.html]

Ah yes, Intel’s famous security hole.

Some people stopped buying Intel CPUs after this feature was introduced.

Ubuntu Manpage: amt-howto - Intel AMT with linux mini howto

IS AMD safer? or are these people buying something else?

Yeah, it’s called AMD DASH, but it’s available only on select CPUs, unlike Intel’s variant.

If only AMT was available in all Intel CPUs, lol.
