HOWTO: Automatically unlock LUKS encrypted drives with a keyfile

[sirlancelot]

hey! thanks for your help! i tried that but it doesn't work here. the boot process doesn't continue at all when it has to read the keyfile from /home. maybe there's another issue according to some karmic problems by mounting cryptsetup-devices. i even can't find anything in the syslog that might give any hint to what's really broken. any further tips 4 me? :-\

iq00, what does your /etc/crypttab file look like?

hello,
I would like to ask another question.
one of my pc has all partition (exept /boot) crypte. Then, at boot time, passphrase is asked immediatly, after 1 or 2 second.
My problem is the following : i would like to remove temporary this password (auto answer to passphrase).
i know, it's a big security hole, but this pc is remote and random reboot. then, in waiting to find a solution, i prefer auto passphrase (with key file ?) than each time move to this pc (3 hours).
Any idea to help me ?
thanks !

Hello dears, I have the same enquiry...
It is very important for me to be able to remote reboot the system, without insert the passphrase. In the same time, I would to preserve my datas in case of my hard disk is stolen.
It is possible?
Foxterrier24, have you found any solution?
