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

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

    Yeah think I’ll get a standalone WiFi smart plug, not connected to my Home Assistant, as a kill switch. But you’re right, it’s overkill.

    I found some weird things in the logs, this goes beyond my knowledge :( See https://lemmy.nz/comment/6192604

      But you’re right, it’s overkill.

      I wouldn’t say that. Sure, it’s not the preferred way of restarting a system, but it is a good backup to have if nothing else works. Remotely messing up the network connections for example.
