Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

If you have a TPM 2 you can use secure boot (custom keys) to allow Linux to decrypt itself if nothing has changed.
Didn't know this thing, I will check about that, thanks !
What do you mean by if nothing has changed? Wouldnt this mean someone could physically steal the machine and then boot it up somewhere else and it'd auto decrypt itself?
Yes. That is possible. However if the hardware configuration/software configuration changes the TPM should trip and prevent decryption.
The attackers would have to break you ssh/terminal/lock screen/other insecure software. However code injection should be impossible because you used custom secure boot keys and ideally a signed unified kernel image. (Can't even change kernel params without tripping TPM.)
You would not be safe if they did a bus listening attack or if your shell pwd is not safe. If that is your threat vector this may not be a good option for you.
