Remove unofficial debian-multimedia.org repository from your sources

http://bits.debian.org/2013/06/remove-debian-multimedia.html

The unofficial third party repository Debian Multimedia stopped using the domain debian-multimedia.org some months ago. The domain expired and it is now registered again by someone unknown to Debian. (If we’re wrong on this point, please sent us an email so we can take over the domain! 😉 )

This means that the repository is no longer safe to use, and you should remove the related entries from your sources.list file.

 

New top500.org list released

As it comes to no surprise, Linux totally dominates on this field.

CyanogenMod10 on the GT-P7501 and GT-P3100

Since the ICS update for the Galaxy Tab 10.1n (German Version of the 10.1 GT-P7500) still has yet to see an OTA update and I was eager to try out Jellybean. I rooted both my Galaxy Tab 10.1n and my Galaxy Tab 2 7.

Galaxy Tab 10.1n
The 10.1n is identical to the internationally shipped 10.1 (aka GT-P7500). The only difference is the Design due to the patent dispute with Apple in Germany.

XDA: Galaxy Tab 10.1 subforum
XDA: How to Root the 10.1

Odin can be used to flash both Tablets, so keep it handy if you want to experiment in the future.
The Current CM10 with Jellybean is very stable and seems to be working fine. I havent fund any critical bugs so far.

The thread for CM10 on the 10.1n can be found . Just remember to install the Googleapps as well if you want to use the Google Services (Market, Mail etc.)

Galaxy Tab 2 7

XDA: Rooting the Galaxy Tab 2 7 (GT-P3100)

If you have installed the Samsung OTA onto the Stock ICS Version 4.0.4 you might experience some difficulties installing the ClockworkMod Recovery. With the OTA, the Recovery will not be persistent and is thrown out after you boot the Tablet into Android. The link above on rooting the P3100 includes the Fix for the nonpersistent Recovery Manager. It includes a fix-recovery Zip that will deal with the problem. The rooting process is pretty much identical to the 10.1

Why install JellyBean?
There is one good reason – performance boost. The User interface is a lot faster and more responsive than ICS. I will add a detailed test for CM10 once it has gone out of experimental status.
So far the sophistication on the Roms nowadays is so good, that even experimental builds work surprisingly well compared to 2-3 years ago from the postings about Custom Roms on the HTC Hero.

Netbooks & Serial Network device configuration

I recently bought some Cisco equiptment (a Catalyst 2924-XL-EN and a 2611 router ) to play around with in my spare time. In order to get the equiptment running for a test lab using telnet configuration, I had to connect via the serial console which can be a hassle due to the lack of serial rs232 ports on modern computer devices.

I bought a Serial USB adapter eager to find out if this will actually work (had some compatibility issues with other devices in the past)

So i got a cheap USB adapter from my local computer store (link on Amazon – this one definitely works with Cisco Catalyst Switches, I will test it on a 2600 router as soon as it gets delivered to me ) and plugged it into my Aspire One netbook running Ubuntu 8.10. After dmesg confirmed the device (in my case ttyUSB0) I needed to get a serial based terminal emulator for console configuration.

Minicom is the good old Linux serial terminal emulator, so a simple

sudo apt-get install minicom

will provide you with the required app on Ubuntu/Debian. If you are running Vista, I recommend tutty since HyperTerminal is no longer included.

The next step will be to set up the device parameters for minicom by running

minicom -s

Set your serial device to the equivalent (should be ttyUSBx) and set the following connection values:

  • Baud Rate: 9600
  • Data Bits: 8
  • Stop Bits: 1
  • Flow Control: none

Now save your config file (the default config is dfl) and launch the program. The values for any Windows software are the same.

Ubuntu on the Aspire one A110L

Ubuntu is up and running properly and the most important devices are running. I had a USB IDE adapter handy so i installed it from the new 8.04.1 CD release.

WiFi will not run out of the box install, here is a quick tutorial to get it running http://wiki.robinward.com/doku.php?id=aao

The install will require some tweaking in order to get everything running nice and smooth. Especially Firefox ist laggy at some time.

I will add some more stuff to the wiki page regarding the UME interface and card reader installation.

Here is a screenshot of ume running in XFCE. As you can see the formatting is a bit buggy

Ubuntu UME

my Acer Aspire One 110L arrived

Got my Acer Aspire One 110L yesterday and just upgraded the Ram from 512 MB to 1,5GB, which is a real pain compared to other Notebooks with a dedicated access bay to the SO-DIMM slot. 0-Day warranty destruction is a must 😉

Here is a video documenting the Ram upgrade

The display quality is really amazing regarding the size of the Netbook. Very clear and sharp but it might take me some time to geht used to the glossy display type.

Overall the build quality is very good although the shiny cover will have your fingerprints all over the place 😀

I was having quite a hard time with the operating system – i simply hate yum because the performance sucks pretty bad when installing applications. The user interface is OK i guess – the Xandros Desktop on the Eee PC is far better (and its Debian powered 🙂 )

I will be going for Ubuntu – either the Netbook remix or the new Ubuntu UME.

Some more footage will follow…

Backtrack 3 goes final

Backtrack, a security and penetration testing oriented Live Boot Linux Distribution has reached Final Stage in the current verison 3.

The Download consists of CD Images, USB bootable Version (which i am booting off a SD Card on my EEE PC) and vmware Images and contains more than 300 tools used by white hats and black hats as well and will give you an introduction on real world attack methodologies on your IT infrastructure.
