I’ve already written about using RealCrypt on Linux, however this explains things a little more thoroughly and should allow you to set up RealCrypt on Fedora 17.
If you’ve read the previous post, you should be able to get RealCrypt installed and ready to use on your computer, except you may find that you receive a message saying that you don’t have the necessary permissions to view the mounted volume.
Setting the Permissions
As mentioned in the previous post, setting the UID and GID in the Mount Options is the solution, but what exactly to set it to?
The values should be set to your user’s UID and GID, which can be found by running the following command in a terminal
cat /etc/passwd | grep [your username]
Here’s my example:
[joe@goblin ~]$ cat /etc/passwd | grep joe joe:x:1000:1000:Joe:/home/joe:/bin/bash [joe@goblin ~]$
The first number is your UID and the second is your GID (although they are very often the same anyway).
For more information about the /etc/passwd file format see here.
Now simply set your UID and GID in the Mount Options field, as can be seen in the following image.
Sorted, you should now be able to mount TrueCrypt volumes and access them easily as your own user.
