Hello, I am trying to use cryptsetup with a disk that has been encrypted some time ago. I'm using Linux From Scratch, and built cryptsetup myself. What I see when I run luksOpen is the following (all commands are run as root) : # cryptsetup 1.7.1 processing "cryptsetup --debug luksOpen /dev/sda1 hdd" # Running command open. # Locking memory. # Installing SIGINT/SIGTERM handler. # Unblocking interruption on signal. # Allocating crypt device /dev/sda1 context. # Trying to open and read device /dev/sda1 with direct-io. # Initialising device-mapper backend library. # Trying to load LUKS1 crypt type from device /dev/sda1. # Crypto backend (gcrypt 1.7.0) initialized in cryptsetup library version 1.7.1. # Detected kernel Linux 4.4.6 x86_64. # Reading LUKS header of size 1024 from device /dev/sda1 # Key length 32, device size 1953521664 sectors, header size 2050 sectors. # Timeout set to 0 miliseconds. # Password retry count set to 3. # Password verification disabled. # Iteration time set to 2000 miliseconds. # Activating volume hdd [keyslot -1] using [none] passphrase. # dm version OF [16384] (*1) # device-mapper: version ioctl on failed: Permission denied # Incompatible libdevmapper (unknown version) and kernel driver (unknown version).

So the question is: how can I make this work, and what else should I provide to you so you can help me? Thank you for any help you could provide. _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
