Hi there ! I have a little box at home, hosting some little services for personal use under freebsd with a full disk encryption (geli). I’m never at home and long power outage often occurs so I always need to come back home to type my passphrase to decrypt the disk.
I was searching this week a solution to do it remotely and found the “poor-guy-kvm” solutions turning a Raspberry like board (beaglebone black in my case) in a hid keyboard. It works fine once the computer has booted but once reboot when the passphrase is asked before it loads the loader menu, nothing. When I plug an ordinary USB keyboard I can type my passphrase so USB module is loaded.
Am I missing something ? Am I trying something impossible ?
(I could’ve asked on freebsd forum but… Have to suscribe, presentation, etc… Long journey)
Not sure about FreeBSD but under Linux I have used SSH based solutions in the past, specifically dracut-sshd to call systemd-tty-ask-password-agent and of course some early network configuration.
