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

PiKVM or a similar device could work for OP - is that what you are thinking of? I've used it and it works well.

I think a lot of people who self-host get caught up in the excitement of getting the services up and running and neglect disaster planning, prevention, and recovery (myself included). Either they put it off for later or don't realize it could be a problem down the road until it happens. We always say not to self host anything you can't live without, and most take that advice, others don't. Not saying OP falls in either category, necessarily, just adding on to some of your points.

Self hosting really is the land of compromise where we all have to balance our requirements, budget, time and effort. Personally, I have a little disposable income that I spend on hardware to host non-critical services so I can learn and tinker. It could all go away and all I will have lost is the time and money I put into it, but I gained some knowledge and enjoyment. Needless to say, I don't have much in the way of backups and monitoring.

PiKVM isn't the board I was thinking of, but same idea, and maybe even better.
