Hi,
I am trying to read encrypted CDroms created using the procedure:
http://www.gentoo-wiki.com/HOWTO_Burn_Encrypted_Optical_Media_With_Luks
but I get the error: ioctl: LOOP_SET_STATUS: No such file or directory.
This procedure was working for me until some months ago when I upgraded
the kernel (now 2.6..25-gentoo-r7) and failed to check this feature. I
don't remember which kernel version it was last that I had this feature
working but it seems earlier then 2.6.23-r3.
This seems to me like a change in the mount options syntax because when
I looked at other web documents I noticed a different syntax. The syntax
that used to work for me:
mount -t iso9660 ... -o loop=/dev/loop0,encryption=AES256
The syntax that I noticed on other sites:
mount -t iso9660 ... -o loop=/dev/loop0,encryption=aes
but when I try the "new" syntax I get a problem with file system type:
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
and in dmesg I get:
ISOFS: Unable to identify CD-ROM format.
Mount to iso image (not encrypted) goes well.
Extracting the content of the cdrom using: dd if=/dev/cdrom | aespipe -d
> image.iso - also works fine.
Any idea?
