Remote solution to decrypt disk at boot (jlai.lu)

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)

You said

gaming wasn't possible because of stutters

I searched what 'stutters' mean, I don't know this word, and I've just found the definition of people who suffer of speech disorder :)

I wouldn't trust USB Ethernet adapter if latency is important to me but maybe I'm wrong it's just superstition. I've just used one time OPNsense for the work and just for checking some network information but I remember saying it was a nice web ui haha

Ah, yeah stutters has different meanings. One being people with a speech disorder and the other one is usually used for display issues (like tearing). It felt like I was using a low refresh rate screen with really low fps, but had 144Hz and 144 fps xD

USB can ramp up latency for sure, should be because of I/O overhead, which usually is ignorable when the HW is fast enough ime.

Now my fingers are itchy to try FreeBSD and OPNsense again, haha. Like I haven't already enough stuff to do and test...

Oh okay , thanks for the definition !

Haha sorry to wake up unreasonable curiosity to you ! :D

[–] plague_sapiens@lemmy.world 2 points 11 months ago

No problem, indeed I like unreasonable curiosity a lot xD
