I'm using slackware 9.1 with kernel 2.6.6 i have loop and crypto loop supported in the kernel, as well as some ciphers, when i checked /dev/ i have 16 loop devices present. but anything i try to use with losetup, gives me.

loop: can't open device /dev/loop0: No such device or address

i've loop and crypto loop both as modules and built in.. i'll keep trying, if anyone has any insight, please direct me to the right place..

Try it as root. If that works you could change the permissions on the loop devices. I don't know what the implications are for security if you do this though.

I've tried it as root and a normal user. the loop devices exist. but don't work, leads me to believe theres something wrong in the kernel, i've read 25 different crypto howtos each of which assumes that these loop devices do work,... as i said i tried modules and built in but can't seem to have any luck..

Thx..

Can you mount ISO images on loop devices?
e.g.
mount -t iso9660 -o loop image.iso /mnt/loop
