[Problem] Difficulty with truecrypt under freetz

[avidscavenger]

Hello,

I am trying to keep some encrypted data on my FritzBox 7270 running freetz stable-2.0 I really don't mind which encryption system I use, but it seems that truecrypt is the one that has been implemented under freetz. However, when I try to use it I get the following:

root@fritz:/var/mod/root# truecrypt --mount /var/media/ftp/uStor01/truecrypt.volume 
Enter mount directory [default]: /mnt
Enter password for /var/media/ftp/uStor01/truecrypt.volume: 
Enter keyfile [none]: 
Protect hidden volume (if any)? (y=Yes/n=No) [No]: 
Error: No such file or directory:
dmsetup

I can't see any reference to the program dmsetup being available, so perhaps this error message is misleading. I also note that I cannot install the module dm-crypt because:

dm_crypt: Unknown symbol crypto_alloc_ablkcipher

I have enabled FREETZ_MODULE_crypto_blkcipher but I note that FREETZ_MODULE_blkcipher is not available because it depends on FREETZ_KERNEL_VERSION_2_6_19.

I'm not sure where to look next, so any help would be greatly appreciated!

Thank you.

In which kernel module the missing symbol is located? This module seems to be missing in the dependencies...

edit: It seems that truecrypt needs "replace kernel" for the 7270?

Thank you - that was my mistake.

I can now modprobe dm-crypt but still have the problem with the missing dmsetup. On the other hand, truecrypt now works with "nokernelcrypto", and doesn't even need dm-crypt. (I needed to replace the kernel to get the ext4 module to mount my encrypted partition.)

Is this the way it is supposed to work, or should we be able to use the kernel encryption modules?
