Comment on I've written a series of blog posts about a "hands-off" self-hosting setup intended for relative beginners.

Something really fun I found out recently, when my friend lost all access to his system except for a single WebDAV share by accidentally turning off all his remote admin access:

If you write “b” to /proc/sysrq-trigger, it will immediately reboot the system (like holding down the reset button, so inherently a bit dangerous).

He was running Nephele with / mounted as the share, so luckily he just uploaded that file with a single “b” in it, and all his remote admin stuff came back up after the reboot.

that’s horrible and funny at the same time.

I will assume they fixed that vuln later

  That’s not a vulnerability. That’s intended and desired behavior. It was really useful in this case too.

    It’s their machine. It’s a front door.
