    [SOLVED] Error using dm-crypt with luks

    Hi guys,

    I'm quite new to Linux, but I hope I can give you all the information you need.
    I'll just post what I did, so this might be self explaining already

    server:~# apt-get install cryptsetup hashalot

    server:~# losetup /dev/loop0 /logcontainer
    server:~# cryptsetup luksFormat /dev/loop0

    This will overwrite data on /dev/loop0 irrevocably.

    Are you sure? (Type uppercase yes): YES
    Enter LUKS passphrase:
    Verify passphrase:
    Command failed: Failed to setup dm-crypt key mapping.
    Check kernel for support for the aes-cbc-essiv:sha256 cipher spec and verify that /dev/loop0 contains at least 133 sectors

    server:~# modprobe aes
    WARNING: Error inserting padlock_aes (/lib/modules/2.6.26-2-686/kernel/drivers/crypto/padlock-aes.ko): No such device
    I'm trying to get rid of this error for a couple of days now but without luck...
    I even reinstalled the system, but it's always exactly the same.

    Thanks a lot in advance!

    had to do a "modprobe dm-mod" first, now it works
