If so, why? You are confusing plain dm-crypt and LUKS. You created the crypto-container (which is not a partition but a whole decive here) as plain dm-crypt and are trying to map it as LUKS. These two are different and not compatible. Try this: cryptsetup create crypt .encrypted mount /dev/mapper/crypt /home/giovanni/cip Arno -- Arno Wagner, Dr. sc. techn., Dipl.
