Here is the executable for Linux: cryptCC.tar

Use at your own risk!

At the moment, I’m thinking about adding features like encrypting a whole .txt file, or something like that.

My next aim is to write an encryption program with a more complex method, such as AES or Twofish. I want to finish it not later than the end of September.

First I identified the codec of my sound card:

drag@hell ~ $ head -n 1 /proc/asound/card0/codec*
Codec: Realtek ALC892

Then i found a blog post regarding this problem. You can read it in German here: http://www.spacefish.biz/blog/2010/06/alc892-b-z-w-realtek-id-892-unter-ubuntu-10-04/

The problem is that the ALSA package of Ubuntu based distributions (maybe others too) does not include a module for the ALC892. But you can easily build it from the package http://files.spacefish.biz/LinuxPkg-5.15rc1.tar.bz2.

You just have to unpack it and execute the install script as root. After that you have to reboot your computer, then everything should work well.

After a while, I found the reason for it. The ACPI APIC support. After disabling it in the BIOS, everything worked fine. An alternative way is to set the boot option noapic.

I don’t know why none of the Linux Distributions can handle it, I hope this will be fixed soon.

This is the new hardware:

• CPU: AMD Phenom II X6 1055T
• Mainboard: Biostar TA890FXE
• GPU: Sapphire HD5850 Toxic
• RAM: 2 x 4 GB Mushkin Blackline DDR3-1600 CL9

As I wanted my system to be silent, I decided to use a noise dampened case. Also a new CPU cooler was needed and of course a fan control.

I bought the following components:

• Noise dampened Lian Li PC-P50 Midi-Tower
• Thermaltake Venomous X CPU cooler
• Lamptron FC2 Fan Controller 5,25″ – black

The system works really good and the temperatures are fine, even after a few hours of crunching (BOINC). I haven’t been able to test a lot more yet, but I will do soon.

• I had to tweek the configuration to make it work with my Samsung TV
• Adding Truecrypt devices was very laborious
• My media folders weren’t updated on new files
• Fast-forward and wind back did not work on most of the videos

So I decided to search for an alternative.

After a little search, I found MiniDLNA. The only thing I had to configure to make it work, was to set the path for the media files. Unlike Mediatomb, there was no extra configuration needed to make it work with my TV.

I found the following init-script, it works well:

#!/bin/sh

# chkconfig: 345 99 10
# description: Startup/shutdown script for MiniDLNA daemon

In summary:

• Works with Samsung TV without any additional tweaks
• Adding devices is very easy, just enter a line in the configuration file
• The media folders are updated on the fly, as soon as there is a new file, you can watch it
• Fast-forward and wind back works on most of the videos

The only thing I could complain about is the missing web UI, but I don’t really need it.

This software is really great, especially if you want to use it with a Samsung TV.

I chose to install Mediatomb. To make it work with Samsung TVs, there were a few additional config tweaks necessary.

The config.xml files in /etc/mediatomb/ and in /root/.mediatomb/ have to be identically, else it Mediatomb won’t start.

First of all you have to uncomment the <custom-http-headers> section.

The next step is to add the following lines to this section:

<add header="transferMode.dlna.org: Streaming"/>
<add header="contentFeatures.dlna.org:  DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=017000   00000000000000000000000000"/>

At last  you have to change

<protocolInfo extend="no"/> to <protocolInfo extend="yes"/>

Now you can (re)start Mediatomb and it should be identified by the TV.

To add the video folders you normally have to go to the web ui http://serverip:49152/.

In my case, Mediatomb could not scan the Truecrypt devices. To solve this problem I used the following command:

mediatomb --add /media/truecrypt3/

That’s it.

By the way, Mediatomb is much better than the Samsung PC Share Manager.

The next step was configuring Samba and mounting the Truecrypt devices. I thought it would be done by that, but then I got 2 issues:

1. The Fileserver was not “visible” in Windows 7.

Solution:

You have to add two things to the Windows registry:

 HKLM\System\CCS\Services\LanmanWorkstation\Parameters
            DWORD  DomainCompatibilityMode = 1
            DWORD  DNSNameResolutionRequired = 0

2. Even though the rights in Linux were correct, all my Truecrypt folders were read-only.

Solution:

If you want Truecrypt to mount the devices in read/write mode, you have to install the ntfs-3g driver and force Truecrypt to mount using it, with the following command:

--filesystem=ntfs-3g

Now everything works fine.
