Setting up encrypted filesystem
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 =...
When I come to the point to give the password for encryption I get that "ioctl" error. I checked the kernel config (18.104.22.168) 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 22.214.171.124 kernel.
