This is about a Lenny install with the stock kernel and modules. I am doing an exercise of encrypting an existing debian partition in a raw qemu image before doing that in production environment.
I first identified the start of the partition (98703360) by doing sfdisk -l -uS lenny.img Then, I configured a loopback defice and mounted the partition losetup /dev/loop0 lenny.img mkdir lenny mount lenny.img lenny -t ext3 -o loop=/dev/loop0,offset=98703360 After backing up, I attempted to create an encrypted partition, but cryptsetup failed with an obscure message: mkdir lenny-backup time cp -ax lenny/* lenny-backup/ umount lenny cryptsetup luksFormat --offset=98703360 /dev/loop0 >Command failed: Failed to write to key storage AFAIU, all necessary modules were loaded. lsmod|egrep dm_crypt\|aes aes_i586 7744 0 aes_generic 29256 1 aes_i586 dm_crypt 11172 0 dm_mod 46184 1 dm_crypt crypto_blkcipher 15236 3 cbc,dm_crypt,ecb Any idea on how create an encrypted partition in a loop-mounted disk image? -- To UNSUBSCRIBE, email to debian-security-requ...@lists.debian.org with a subject of "unsubscribe".
