HowTo: Feisty Fawn & dm-crypt / LUKS

[hyper_ch]

What happens if you partition the drive first and then create an encrypted partition (instead of using hda --> using hda1 (or whatever the partition number is...)

[logical_thought]

Same thing happens.

that is strange

i created an encrypted partition using dm-crypt, mounted at boot with a prompt for the passphrase, it's working quite fine

i just have a little problem, with feisty, my hard drives are mounted in random order

my /etc/crypttab :

# <target name> <source device>         <key file>      <options>
Stockage        /dev/sdb1       none    checkargs=ext3,tries=5

but sometimes, this drive is recognized as sdb, sometimes as sdc ...
so mounting the encrypted volume fails
is it possible to use uuid or label in /etc/cryptab ?

I know this is an "old" how-to, but it comes up on a google search.

In Ubuntu 8.04 (hardy) the name of the kernel module was changed from aes to aes_common :

modprobe aes
WARNING: Error inserting padlock_aes (/lib/modules/2.6.24-16-generic/kernel/drivers/crypto/padlock-aes.ko): No such device

Instead, modprobe aes_common:

modprobe aes_generic

I'm getting the command failed thing. Anybody know how to fix that? I'm running 8.04 with all the updates installed.

barry@Box:~$ sudo cryptsetup luksFormat /dev/sdb1

WARNING!
========
This will overwrite data on /dev/sdb1 irrevocably.

Are you sure? (Type uppercase yes): Yes
Command failed.

Same if I try,

barry@Box:~$ sudo cryptsetup luksFormat /dev/sdb

WARNING!
========
This will overwrite data on /dev/sdb irrevocably.

Are you sure? (Type uppercase yes): Yes
Command failed.

Son of a !!! Man, that's freaking funny! I've been beating my head against this for three days.

lol

normally it does not matter you can you type just a "y" and press enter. BUT because it will destroy all information (or sort of destroy everything) they made it a little bit harder

Yea, and I was reading it as Yes, and not YES. Oh well, works now, though I've broken something else installing a theme. Think I've got it straightened out though.
