When using TC 6.2 or newer use:

truecrypt --filesystem=none /path/image.tc

mkntfs /dev/mapper/truecrypt1

To create a arbitrary FS (i.e. ext2):

truecrypt -N 1 /path/to/created/volume
export MKE2FS_SYNC=1}}
mkfs.ext2 /dev/mapper/truecrypt1
truecrypt -d /path/to/created/volume

I have a problem when mounting truecrypt volumes because after mounting you chmod doesnt affect the files that are there in the encrypted volume.. WHy is this? I'm running TC on FC10

Beautiful thanks! For a newbie using a file on an external USB drive on an Eee I found the following version worked fine:

truecrypt --filesystem=ntfs-3g D:/{tc filename} /mnt

In reply to anonymous, to mount a pre-created NTFS volume created by Truecrypt under Windows, it is very easy. The tricky part is to make the volume writeable.

Below is the command I used as a normal user:

truecrypt -u --filesystem ntfs-3g /dev/sda2 /mnt

-u switch makes for user mounted options so that you can mount it as a normal user and access it.

--filesystem ntfs-3g tells Truecrypt to mount it with a writeable NTFS partition because by default NTFS is mounted read-only. Of course you need to have ntfs-3g package installed on your system in order to write to NTFS volumes.

I hope this helps.

Thank you Sharad Popli for the info. I updated the blog posting.

In reply to anonymous: it is perfectly possible as long as your linux distribution has the ability to read NTFS partitions.

I recently skimmed through all the posts in this blog, and I wanted to let you know that I really appreciate all the good information and hard work you’ve done here. I particularly like your examinations of Security Now! as I’ve been listening to that podcast since its inception. You do a very good job of pointing out things that Steve Gibson gets wrong, but you always give him credit when he gets things right, too. You definitely seem to be interested in getting sound answers to computer security questions rather than in making personal attacks. Keep up the good work!

When creating TrueCrypt volumes under Linux, you don't _have to_ specify FAT as the filesystem.

1. truecrypt --create test.tc
Create the volume (specify None for the filesystem)

2. truecrypt test.tc
Map the volume (it prompts you for your password)

3. truecrypt -l
List the mapped volume (you should see something like: /dev/mapper/truecrypt0)

4. sudo mke2fs /dev/mapper/truecrypt0
Make the file system you want

5. truecrypt -d
Dismount the mapped volume

6. mkdir mnt; truecrypt test.tc mnt
Mount the volume on your filesystem

7. sudo chown user.group mnt
Replace user.group with your appropriate values. This is needed because the filesystem on mnt is owned by root. You will probably need to do this only once.

Enjoy :)

(Note: I've tried the above on SUSE Linux, but it should work across all distributions)

THANK YOU! I downloaded the new Truecrypt 4.3a .deb package for my Ubuntu 6.10 and kept getting some kernel module error when trying to actually Truecrypt mount. I followed your instructions, downloaded the Truecrypt source, and it worked like a charm! Great step-by-step walkthrough!
