Hi all,

I’ve compiled Tcrypt 4.3 on Feisty, without any errors or warnings, I have mounted my existent tc volume, after inserting the password, I got this error:

Unable to make device node for ‘truecrypt0′

The Tc volume have been mounted correctly, but I would like to know the cause of this error. Any idea, guys?

Thanks, the .deb for the new 4.3 version kept giving me kernel module errors. Compiling from source was simply a matter of following this guide only substituting the new version number (4.3 instead of 4.2a)

Daniel Spiewak:

Or, better yet, this how-to could use $( ) instead of back-ticks for easier non-geek typing.

Maximander, the kernel and initrd still would have to be on the disk as cleartext, wouldn’t they?

“Why isn�t this capability built into Linux distros yet?”

Answer: because you pretty much need so many libs and such just to do the decryption that it’s (close to) impossible to install the whole OS inside an encrypted container. Now 2.6.20 has KVM (hyper visor like virtualization) so maybe a host OS to decrypt and then a guest inside an encrypted drive. Or, just this week, seagate announced the first fully encrypted consumer product, but they’re using hard/firmware to do their en/decryption so the OS on the drive doesn’t have to be aware of it.

Anyway, eventually, I’m sure a distro will come out with a BIG initrd (ramdisk used to start up before the kernel and modules are all up and running) where the encryption is done so that the drive could be encrypted, but the more complex, and secure, you want it, the harder it will be to do without a running OS to power it.

Hi,

I just followed the instructions on a very new Ubuntu Edgy installation and had one tiny obstacle to overcome.

Before I could make -d -C linux modules_prepare, I needed to cp /boot/config-2.6.17-11-generic linux/.config

After that everything worked for me just as explained.
Thanks for this great guide!
All the best,
Aron

I should clarify this, I have a laptop, with one (blank) hard drive in it. I would like to encrypt the entire hard drive, then install Ubuntu Edgy Eft onto that drive. I know I need two partitions to install it, the swap partition and the root partition. Why isn’t this capability built into Linux distros yet? With security being so important these days it should be set up to take a blank drive, create the necessary partitions, encrypt them, then install onto them. Then we would have some good security. Also I don’t see why there is such a thing as unsecure web browsing even. The experts should be able to make everything automatically encrypted from the moment we connect. This is ridiculous that anybody with the right software can intercept everything we send or receive from our computers. Why isn’t the internet all SSL by now?? But alas, I digress. Thank you for your wonderful articles, Mr. Howtogeek, keep up the great work!

I wonder: how do you encrypt an entire empty drive with truecrypt and then do a fresh install of edgy ubuntu? I want the whole disk encrypted, not just a partition. Is this possible?

Mike,

Thanks, I’ll check that out, and update the article if it works for me.

I always test things out myself before writing an article. Quality is important =)
