Truecrypt Or Truecrypt Alternative On Centos?

b10m3ch4 · 12-11-2009, 09:22 PM

I have been unsuccessful in repeated attempts to get the latest version of TrueCrypt to compile on CentOS release 5.4 (Final), but I am in great need of a virtual drive setup to store my files in, on my remote servers. Has anyone managed to get TrueCrypt installed on the latest CentOS, or does anyone know of a more Linux-friendly alternative to TrueCrypt that serves the same purpose?

My company is talking about going back to Windows if we can't figure this one out...please help

This web log article http://vinnn.blogspot.com/2009/01/tr...-centos-5.html says he has and as a bonus he lists what doesn't work as well. (Maybe you should post where your build process fails?) Here's a nice overview of encryption methods: http://www.debianadmin.com/filesyste...for-linux.html (you didn't state you require cross-platform compatibility and most won't be).

If they want the tuesday-is-my-fun-day, monthly reinstalls and the per-seat yearly license fees, so be it. Personally speaking I'm not fazed by that kind of talk...

Here is a link to a repo with the latest truecrypt rpm http://www.lfarkas.org/linux/package.../5/i386/other/

Now I am getting the following errors, are my installs missing something that is usually there maybe?

[root@fast appz]# truecrypt
truecrypt: /usr/local/lib/libpng12.so.0: no version information available (required by /usr/lib/libwx_gtk2u_core-2.8.so.0)
truecrypt: /usr/local/lib/libpng12.so.0: no version information available (required by /usr/lib/libcairo.so.2)

I already have libpng installed of course:

Setting up Install Process
Package 2:libpng-1.2.10-7.1.el5_3.2.i386 already installed and latest version
Package 2:libpng-devel-1.2.10-7.1.el5_3.2.i386 already installed and latest version
Nothing to do

All the errors I run into trying to install TrueCrypt are related to GTK, Wx, and issues related to the GUI....none of which I care anything about or need, as I am trying to get truecrypt installed on a remote server, via command line. It installed perfectly on an OpenSUSE install, but I really hate that OS for servers

Does anyone have a way to install TrueCrypt from the command line in a server environment? Without all the GUI application dependency hell?

If you enter "./configure --help" is there an option whether to build the project with gui support?

You did as for an alternative to truecrypt in the first post. You could use "cryptsetup" & the kernel's luks support instead. Here is a example creating a 200MB encrypted file:

Code:

#create a file with pseudo-random contents
dd if=/dev/urandom of=testvirt bs=$((1024*1024)) count=200

#setup a loop device.  The output of this command will be which loop device to use.  My example returned loop0.
sudo /sbin/losetup -fs testvirt

#use luksFormat to setup the encryption.  It will ask for your passphrase to use.
sudo /sbin/cryptsetup luksFormat /dev/loop0

#create the encrypted device
sudo /sbin/cryptsetup luksOpen /dev/loop0 cr_<file>

#this created a /dev/md-0 device which needs to be formatted yet.  You could use the created /dev/mapper/cr_<file> device in the next command instead.
sudo /sbin/mkfs.ext2 /dev/md-0

#now to mount the device
mkdir ~/secret
sudo mount /dev/md-0 /home/user/secret

To use the device after it has been setup:

Code:

sudo /sbin/losetup -fs <file>
sudo /sbin/cryptsetup luksOpen  /dev/loop0 cr_<file>
sudo /sbin/mount -t ext2 /dev/md-0 /home/user/secret
