How to remotely reboot a Linux host if SSH fails to connect? (lemmy.nz)

Edit2: Thanks all for your responses! I have checked the logs, https://lemmy.nz/comment/6192604, and based on that removed tracker-miner-fs as it's a search/index tool which I don't need. No idea why it took over all memory. I'll also get a WiFi Smartplug as a kill switch. Hopefully that solves it. Thanks again heaps!

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

Thanks, I've got a HP SFF as well. Not 100% sure how to turn it on though from Ubuntu. There's a software based version: https://manpages.ubuntu.com/manpages/xenial/en/man8/watchdog.8.html

But I guess that's not the one using the motherboard watchdog function.

You can set it in the BIOS, regardless of OS.

You need an OS app to run and a setting in the BIOS. The app at the OS level gives a heartbeat to the watchdog module on the mother board. If you miss some heartbeats, the firmware on the motherboard sends the reset command.
