Visca, diria que [ho has] aconseguit!!
root a ubuntu:/mnt/home/.ecryptfs/david# sudo ecryptfs-recover-private
.Private
INFO: Found [.Private].
Try to recover this directory? [Y/n]: Y
INFO: Found your wrapped-passphrase
Do you know your LOGIN passphrase? [Y/n] Y
INFO: Enter your LOGIN passphrase...
Passphrase:
Inserted auth tok with sig [f1d6ffd7d325ae9d] into the user session
keyring
INFO: Success! Private data mounted at [/tmp/ecryptfs.QEOglZH2].
Ara se suposa que aix[o esta muntat oi_
Com hi accedeixo per copiar-ho?
