Package: libpam-mount
Version: 1.10-1
Severity: important
File: /sbin/mount.crypt
/dev/sdb1 contains a LUKS volume with only one key-slot: 0, which comes from a
keyfile.
Cryptsetup opens it without problem:
aris:/home/encmp/gpall# cryptsetup --key-file /home/encmp/gpall/proj/keyfile
luksOpen /dev/sdb1 testluks
sh: /sbin/udevsettle: No such file or directory
key slot 1 unlocked.
sh: /sbin/udevsettle: No such file or directory
Command successful.
aris:/home/encmp/gpall# ls -la /dev/mapper/
total 0
drwxr-xr-x 2 root root 100 2009-05-12 15:16 .
drwxr-xr-x 15 root root 3900 2009-05-12 15:16 ..

brw-rw---- 1 root disk 254, 1 2009-05-12 15:16 testluks
aris:/home/encmp/gpall#
Now, I am trying to use mount.crypt in order to mount it (I luksClosed testluks
of course after the previous test).
The problem is I can't get mount.crypt to pass the keyfile option to cryptsetup:
# mount.crypt -v -o keyfile=/home/encmp/gpall/proj/keyfile /dev/sdb1
/media/dataspace
command: [readlink] [-fn] [/dev/sdb1]
command: [readlink] [-fn] [/media/dataspace]
mount.crypt: No openssl cipher specified (use -o fsk_cipher=xxx)
OK, I give the cipher (and the hash), although I can't understand why doesn't
it autodetect like cryptsetup does:
aris:/tmp/test# mount.crypt -v -o
fsk_cipher=aes-256-cbc,fsk_hash=ripemd160,keyfile=/home/encmp/gpall/proj/keyfile
/dev/sdb1 /media/dataspace
command: [readlink] [-fn] [/dev/sdb1]
command: [readlink] [-fn] [/media/dataspace]
Password:
mount.crypt(loop.c:266): Using _dev_sdb1 as dmdevice name
command: [cryptsetup] [luksOpen] [/dev/sdb1] [_dev_sdb1]
sh: /sbin/udevsettle: No such file or directory
Command failed: No key available with this passphrase.
mount.crypt(loop.c:198): cryptsetup exited with non-zero status 255
I also tried with various combinations of cipher and hash (eg. sha1 for hash,
and aes256 for cipher) all with the same output.
Why does it even ask for a password since I give a keyfile?
I tend to think that there is a bug, and it is not my fault. In the latter
case, I am very sorry for the report...
Extra info: My /etc/crypttab is empty.
Here is the LUKS dump, in case you need it:
