(PROBLEM DISAPPEARED) trying to create encrypted hard-disk partition

[heinkel_111]

Hi
A week back I bought a Toshiba Sattelite U405 laptop and I am installing Kubuntu Hardy Heron on it. (I am actually writing a long blogish experience document I will publish when I am done. )

However, I am stuck on the "encrypt harddrive" step on my to-do list. I am trying to follow the Encrypted Filesystems HowTo on the Kubuntu/ubuntu website wiki. However, when I come to the part involving cryptsetup, I start getting an errormessage that does not make a lot of sense to me.

(here comes some more code...need to login from the other machine, will be right abck with edits...)

OK, this is a good one...I crashed the computer when I tried to login from the new laptop. At that time I had done a lilttle fumbling on the filesystem, such as disconnecting my /home. (Note that I had followed the how to instructions and the partition to be encrypted, formerly known as /home was disconnected when I first tried to run cryptsetup)
Upon rebooting the laptop I had to manually mount another partition as /home in order to get a graphical Kubuntu desktop. Then I opened up a Konsole shell, and re-entered the cryptsetup command exactly as I had done about 6 times before (according to history).

The only difference was that this time it worked and my ioctl errormessage that I had planned to copy/paste to this thread just wasn't there anymore.

Well well, I don't know what to say about this except it was a happy ending if not one that inspired great confidence and I would be troubled to rely on this mechanism for a production system. Luckily my laptop is for fun

As you might have noticed, the 8 other How-To's the author referred to in his article, have now become 12 other How-To's (and that's just at the Ubuntu Wiki). I conclude that this is a rapidly changing state-of-the-art. Why did you choose the one that you used?

askrieger, I will give you the final answer when I have been able to get something to work :P Reading between the lines of your post YES there is a lot of confusion and concerning the ubuntu HowTo section it is definetly not very impressive on quality control, as I have found several pieces of confusing and/or misleading information and so far I don't have a working encrypted HD thing working for linux

Having said that I have not actively worked on the problem for about a week due to other commitments so I will report back...I am actually writing an experience report sort of HowTo Toshiba Sattelite U405 and kubuntu, although HowTo is starting to feel a little discredited in this context.
