eee-control for Ubuntu 9.10 (Karmic Koala)

I have been waiting patiently for Grigori Goronzy, the developer of eee-control to release a version of the utility for Karmic Koala (URL http://greg.geekmind.org/eee-control/). However, three weeks since Karmic was released, Grigori has yet to release an update.

Dan Amlund has downloaded the latest version Grigori released for Jaunty Jackalope (0.9.4) and fixed it so that it will install on Karmic Koala. I have installed iton my EeePC 701 and everything seems to be working (your mileage may vary).

To get Dan's version of eee-control which works on Karmic Koala,visit Ubuntu Geek's article at URL http://www.ubuntugeek.com/howto-install-eee-control-in-ubuntu-9-10-karmic.html

The ever important /tmp folder...

I was busy trying to see if I could speed up Adobe's flash which crawls on Linux systems, yet on the same computer running Windows XP, the same flash application runs much faster. I Googled the net and tried the recommendations other users had posted. I tried one of those recommendations and noticed that the application started quick enough but over time, slowed down to a crawl. Even if I reload that web page, the application still crawled.

What did I do? I said to myself, maybe if I deleted the /tmp folder, the flash application would reload and work like normal. I then started the command shell and typed:

sudo rm -r /tmp

Thinking that if anything goes wrong, just restart Ubuntu and it should recreate the /tmp folder since I've came to an understanding that Linux will delete all files in the /tmp folder at startup anyway. Once I deleted the folder, I didn't get the results I was expecting and said to myself that I best restart my computer.

Computer restarts and loads up in about 30 seconds (Jaunty does that on my Pentium M 1.73GHz computer). I then give my login credentials but get an error message saying "mkdtemp: private socket dir: Permission denied".

I Googled the error message (from another computer) and it turns out that if you delete the /tmp folder, Ubuntu will recreate the /tmp folder but with the wrong permission settings!

How did I solved this? I restarted Ubuntu in recovery mode, then issued the command:

sudo chmod a+w /tmp

Restarted Ubuntu and problem solved. Now you know how to DoS your own machine and fix it. :)

Create a .deb package from source files

If you are like me, you will find that you need to install a lot of application software from the source code and compile the build for your specific platform. The most common way of installing the program is to download the source (usually it's a file with .tgz or .tar.gz extension to it), unpack the file, go into the directory where the source files are extracted, run the configure tool, followed by the make and finally the make install commands.

wget http://site.com/source/program-1.0.tgz
tar -zxvf program-1.0.tgz
cd program-1.0
./configure
make
sudo make install

This will download, extract, compile and install the program in your Ubuntu eco-system.

If you have to do this to a few machines or need to reinstall your computer ever so often, it would simply be easier if you could create a .deb file and simply install the program when you need to which is faster, and you do not need the installation of compiler, make utility, header and dev libraries.

There is a tool called checkinstall which you can install from the Ubuntu repository. To do that, simply run the command:

sudo apt-get install checkinstall

Once that is installed, when you want to create a .deb file, you do pretty much everything like normal but instead of installing the program with "sudo make install", you create a .deb at this point with the command "sudo checkinstall" which will create the .deb file for you.

You can then copy the .deb file into a safe place, and when you need to install in the future, copy the .deb file to your local directory and issue the command "sudo dpkg -i package.deb" which will install the applictaion for you without the need for the source download, dev libraries, compiler, etc.

Note: These are basic instructions that may not always work. Some packages require additional dependencies and optional parameters to be specified in order to build them successfully.

Using BackTrack 4 applications on a Ubuntu (8.10 Intrepid) build...

There is a security tools distro called BackTrack which in it's own words:

BackTrack is the most top rated linux live distribution focused on penetration testing. With no installation whatsoever, the analysis platform is started directly from the CD-Rom and is fully accessible within minutes.

To know more about BackTrack, click here.

The latest version of BackTrack (BackTrack 4) does away with a simple build that is only good for the next six months (you could never really update the build completely). It now uses Ubuntu (8.10 Intrepid) as a base so that application and updates are easily available and updated.

As much as I like BackTrack which uses KDE, I am a GNOME person. Instead of using the BackTrack build, I wanted to use Ubuntu, yet leveraging on the vast amount of tools that BackTrack offers. To do that, you must add the following into your /etc/apt/sources.list file:

deb http://repo.offensive-security.com/dist/bt4 binary/

Before you can start using the BackTrack repository, you will need to install the GPG key so that the APT tool does not give you an error message saying the repository has no public key. To do that:

wget http://apt.pearsoncomputing.net/public.gpg
sudo apt-key add public.gpg

You can then issue the apt-get update command and download the list of application that the repository hosts and use the Synaptic Package Manager to view what is available and install the applications that you want.

Note, you should only do this on Ubuntu 8.10 Intrepid as all the work the BackTrack team does is using this version of Ubuntu. I am assuming you are well versed in the ways of Ubuntu and know when you need to use root access to do some of the actions stated in this article.





Speeding up your Ubuntu updates -- Malaysian update

I had posted an article called Speeding up your Ubuntu updates on 7-Mar-2009. What I had failed to realise was the fact that Ubuntu updates are now hosted on a Malaysian site at the Multimedia University at archive.mmu.edu.my since 21-Jun-2008.

Jaunty users will see the Malaysian host when they run the Software Sources program in Ubuntu. Earlier distros will need to manually change the source in /etc/apt/source.list file. Go to this link for more details.

Keeping yourself updated (really useful links) - 20090530...

I have found that no one person or website can keep track of security issues. Below are the addresses of some sites that I visit or subscribe to to keep me updated.
