loop-aes-modules-XXX (looks like you have them) loop-aes-utils loop-aes-testsuite sharutils after install of loop-aes-modules, module loop must be removed and then reloaded in the kernel to get to the new loop-aes module (only once if you haven't rebooted since install: rmmod loop modprobe loop command would be: losetup -e serpent[128,192, or 256] /dev/loop[1,2,3,4,5,6,7, or 8]\ ~/file.bin file.bin must have a physical size already, example: dd if=/dev/urandom of=~/file.bin bs=1024 count=1000 will block out a working space for the file... change the count to vary the size... Look here: <http://www.debian-administration.org/articles/81> And here: <http://www.hermann-uwe.de/blog/howto-encrypted-usb-thumb-drives-and-usb-hard-disks-using-loop-aes> Good place to start.
