Setting up encrypted filesystem

Hi there,

please, don't tell me, to read the manuals and HOWTOs I'm over it.... So I need some effective help.

I set up couple of months ago an ancrypted filesystem with the help of loopback device.
Now I want to mount this encrypted filesystem to another linux box but I cannot do that. There's something to do with "ioctl". (Of course on my computer I can mount it). So I thought to set up a new loopback device on the other computer. I did all the stuff:
dd if =...
losetup... BUT!

When I come to the point to give the password for encryption I get that "ioctl" error. I checked the kernel config ( everything looks fine, loopback device is compiled (not as module) also the Cryptgraphy support, and the ciphers (all are compiled in, not as modules just to make it sure...).

So I really can't see what I've done different compared to my previous encrypted filesystem set-up. Can anyone give me some hints?

Is there maybe something to do with device-mapper settings/packages?

I'm using debian sarge distro with kernel.

As far as i know, if you have the support compiled into the kernel as you say, I dont see any reason why it shouldn't mount!

Maybe just a 'glitch'? I dunno.
