Hi, I am using kernel version 2.4.19. I have applied the patch-int-2.4.19.1 and the loop-jari-2.4.18.0.patch. I successfully compiled and installed the patched kernel. Next was to patch util-linux-2.11u with util-linux-2.11r.patch and complile it. It does not work out as descibed in the crypto-howto, but I compliled the whole package instead and copied the three resulting binaries mount, umount and losetup to the apropriate locations. When I try to setup a loop device with encryption I get the following error: # losetup -e aes /dev/loop0 ~/.crypto Available keysizes (bits): 128 192 256 Keysize: 128 Password: The cipher does not exist, or a cipher module needs to be loaded into the kernel ioctl: LOOP_SET_STATUS: Invalid argument # The file ~/.crypto was created before as described in the howto. /proc/crypto/cipher/* proves that the aes cipher is available: # ls /proc/crypto/cipher/ aes-cbc aes-cfb aes-ctr aes-ecb aes-rtc # The howto does not have any further advice. I really thought I could finally start working with this - but now I do not know what else to do. Can anybody please help out?
