After rebooting I succeeded to created a luks usb drive as well as a luks
container. Case closed!
2008/9/2 Philippe A. <futhark77(a)gmail.com>
My attempts to open a luks container fail with the following
messages:
sudo cryptsetup luksOpen /dev/loop2 test.crypted
Enter LUKS passphrase for /dev/loop2:
key slot 0 unlocked.
Command failed: Invalid offset
As a result, the mapper never gets created in /dev/mapper.
The commands I am using to create my container are the following:
dd if=/dev/urandom of=test.crypted bs=1M count=256
sudo losetup -d /dev/loop2
sudo losetup /dev/loop2 /phil/test.crypted
sudo cryptsetup -c twofish -s 256 luksFormat /dev/loop2
The resulting container appears to be valid as shown by cryptsetup
luksDump:
LUKS header information for /dev/loop2
Version: 1
Cipher name: twofish
Cipher mode: cbc-plain
Hash spec: sha1
[snip]
However, no mapper after the luksOpen.
I have a non-luks 'vanilla' container that works. Can anyone help me figure
what I'm missing?
Thanks!
