[syscon-hh <syscon.kono@xxxxxxxxxx>]

I have a broken Jaunty system with home-directory separately, located on
/dev/sda3. All data in the standard-folder "/var/lib/ecryptfs/laura-bnb"
no more available - only the passphrase has been recorded (to paper).

Starting a Jaunty live-cd, and on desktop using a terminal. First I
mount the brocken system typing:

sudo mount -t auto /dev/sda3 /mnt followed by

sudo mount -t ecryptfs /mnt/home/laura-bnb/.Private /mnt/home/laura-bnb

The next input requieres to insert the "passphrase" followed by the
recommendable values. Resulting allways as read above!

Where the command "ecryptfs-add-passphrase --fnek" to use??

Bug description:
Binary package hint: ecryptfs-utils

- ecryptfs-utils_73-0ubuntu6 with Jaunty
- ecryptfs-utils_75-0ubuntu1 with Karmic

Trying to discover data from a crashed system with encrypted home-directory, it is recommended to use:

sudo mount -t ecryptfs /home/<username>/.Private  /home/<username>

But after inserting the passphrase and answering the shown options, the volume is mounted to the given mount-point - but the name of files - and volumes are still encrypted, The content is partly readable.

It seem to me. the following is running wrong -> On a healthy system you will find inside /etc/mtab:

"ecryptfs_sig=14140887552e0bec,ecryptfs_fnek_sig=de5d090606c60111,ecryptfs_cipher=aes,ecryptfs_key_bytes=16", with different _sig values

but on a broken system after using above command both values are the same

"ecryptfs_sig=14140887552e0bec,ecryptfs_fnek_sig=14140887552e0bec,ecryptfs_cipher=aes,ecryptfs_key_bytes=16", independent of choosing (y/ n) for plaintext as well for foldername decryption (y/n).

These have been testet and verifyed with Jaunty and Karmic - both the same results.
