Hello,
for backup purposes I want to write on an encrypted partition with my Debian
Sarge system and read from that partition with Knoppix or another live-cd
Has anybody a similar setup running?
What I did:
On the Sarge side:
modprobe blowfish
modprobe cryptoloop
losetup -k 256 -e blowfish /dev/loop0 /udev/mdisk5
mkfs.ext3 /dev/loop0
mkdir /mnt/crypto
mount -t ext3 /dev/loop0 /mnt/crypto
<write on that partition>
umount /mnt/crypto
losetup -d /dev/loop0
Works fine I can remount the partition and read and write.
When it comes to knoppix now, I tried
losetup -e blowfish256 /dev/loop0 /dev/sda5 # did not accept -k parameter
mount -t ext3 /dev/loop0 /mnt/crypto
Then I got the error message:
EXT3-fs: unable to read superblock
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or other error
(aren't you trying to mount an extended partition,
instead of some logical partition inside?)
In some cases useful info is found in syslog - try
dmesg | tail or so
Any hints are welcome.
Thanks,
Rainer
