Encrypted loopback filesystem
I thought I would experiment with creating an encrypted loopback
filesystem. I've generated a file of random numbers, but I can't attack
it to /dev/loop0:
# losetup -e serpent /dev/loop0 $(pwd)/file.bin
ioctl: LOOP_SET_STATUS: Invalid argument
I did a quick google search, but what I've found refers to making sure
that you have the modules and util-linux installed, and I 've got those
(using Debian/Etch), and the loop and serpent modules are loaded.
What else can I check for?
Thanks for your help,
