I am having a huge problem with SPAM comments last weeks. Because of that my site was already disabled by my hoster because my database and traffic exceeded the limits. For this reason I have disabled commenting without user account. If you would like to get in contact with me, please use the contact form. Will see how I can solve the problem…

I have successfully configured a VPN connection to my home router, thus, I was able to access machines in my private LAN. Moreover, I wanted to tunnel my whole Internet traffic over this connection. Even a google search could not answer, how I could solve this with the network-manager which is used in most Linux desktops.
Finally, I figured it out. You need to go into the configuration of the particular VPN, further into the tab IPv4-Configuration, click on button routes and there you have to remove the tick from box which is probably named in English something like “Use this connection only for resources of current network”. German screenshots are attached below.

Happy New Year everybody!
This follow up post to my last article about using Truecrypt on my ReadyNAS 102 (with two Seagate Pipeline HD ST2000VM003 – 2 TB – 5900 rpm RAID 1) (http://www.ceh-photo.de/blog/?p=809 ) will examine the transfer performance while using Truecrypt.
For comparison I have tested as well on my desktop PC:
My computer and the NAS are connected by a 100mbit Router only, unfortunately not by Gigabit-Ethernet. If someone could provide some test results using a 1Gbit router, I would be glad to get them.
The test container had a size of 2GB formatted with FAT32 and I used the default encryption settings with AES and RIPEMD-160 hashing. The test script first wrote 1GB of random data and read it afterwards.
See the test script below:

Since I own a Netgear ReadyNAS 102 I was wondering how I could use encryption for special content in a convenient way. Because the Netgear firmware does not provide an encryption feature inside its ReadyNAS OS wrapper on top of the underlying Debian Linux I decided to have a closer look on Truecrypt, which I already have in use on my other desktop and mobile computers.
Because Truecrypt binaries are not available for the used ARM architecture the first required step was building Truecrypt from source. During my research I came over a posting which explained the build process step by step.
If you really want to build it on your own, be aware of my comment inside the forum thread above. If you just want to go ahead, I have simplified the procedure for you with a prebuild binary available on my personal Debian-Dropbox-Repository:

I just realized that I forgot to change the timezone/time settings in my camera since I am back from Asia (~6month). In order to fix the timestamp on all my photos I made during this time period I used exiftool for doing this on the command-line.
Move all timestamps minus 6 hours for all picture files (JPG and RAW) in current directory.
Check if everything is like expected and delete the backup copies in current directory:
Because I am working with Corel AfterShot (former Bibble) I had another problem. AfterShot is dumping the timestamps for all adjusted files into the xmp file and is also using these timestamps as first choice for displaying inside the application. But I figured out, that this information in not required and I just deleted it from the xmp file with sed.
Delete timestamp lines from mentioned files for all xmp files in current directory:
Actually a simple operation, but maybe helpful for someone else.

It was a very, very awesome experience, even it was stressful for me to manage to give all the help the people needed.

Many of you guys have maybe already thought, that I will not continue the Android-x86 development for the Acer 1825 and all the other laptops I was supporting as well in the mean time, because there was a long time without any updates. But actually the reason was, that since I am in Malaysia I had not much time to work on this and much more I did not have a proper machine for building. So my plan was to continue the development once I am back at home in Germany, what is actually very soon.
But fortune was taking another way, so sad for me and also for all of you guys who used my build all over the world, my poor, poor Acer was snatched from me while I was working in a Park me around a week ago. This is not only sad, because I lost my nice hardware, even so I lost data…..So very disappointing for me…. I am very sorry, but now I do not own a x86 touch device anymore and that is the reason why I will now finally terminate my Android-x86 efforts…even I had other plans…
