How do you deal with LUKS? (lemmy.world)

So I was reading this. And it seems pretty good. In my current set up if my server ever just restarts or something I just kind of don't have it until I get home. Which is no issue because my set up is just local anyway hehe. Still I am thinking of changing my set up to be more of a real server. I don't really need the encryption, but I have it and feel I should use it out of some principle of the matter.

So what is the workflow that people use if they need to restart or there is a power outage and want the server to turn itself back on, but no one would be around to unlock the LUKS?

I use Clevis and Tang setup. I installed tang on RPi which also my NUT server. I installed clevis on all my Linux servers for the network-bound disk encryption.

I have a USB drive with the key on it. The primary purpose for LUKS for me is so that drives I replace don’t need to be wiped, so I just leave the USB drive in all the time. Makes it so it boots automatically.

If I lived in a place I owned, I’d stash a rpi somewhere deep and have it do network dropbear automatic unlock to protect the data if the server is nicked. Till then it’s yolo

The top paragraph is something I was curious about, the second reminded me that I have an RPI 3B that is not doing anything...

You can configure Dropbear to allow SSH unlocking. I have also heard of some key management software over network that can perform this role for you as well.

This is how I do it. I followed this guide to get it set up, and this one to make it work behind a VPN (Tailscale)

I've never heard of Dropbear. Seems like a handy thing

You could setup LUKS TPM unlocking.

I actually looked into that, but my server is a very old optiplex that dos not have one.

Maybe a setup FIDO2 LUKS unlocking, but that requires a security key: https://www.privacyguides.org/en/security-keys/
