Installing Gerix (from Backtrack) into Ubuntu

Gerix is a 802.11 wireless pentesting tool. I find it especially effective against WEP protected wireless APs. Outdated security protocol which is still the default security that O2 uses in the UK (hint, if you’re using O2’s default wireless modem, get away asap… it took me 30 mins to get into such a weakly protected network). Gerix is included in the backtrack repositories.

So my (unoriginal it seems) idea was to include the backtrack repositories into the ubuntu reps I use and download the tool. Most websites pointed to outdated repositories that were not responding, however I managed to find the correct repositories here:


sudo echo “deb pwnsauce main microverse macroverse restricted universe multiverse” >> /etc/apt/sources.list

wget -q -O- | sudo apt-key add –

sudo aptitude update


I then proceeded to use Synaptic to install Gerix, but was running into a problem since the process exited with error code 1. Turns out the package was (quite rightly) trying to install to the default path in Backtrack:


Once the above folder structure was created, the install finished with no issues.

  1. Hi, i did exactly as you said, but, now I’m at a loss as to how to start gerix. Could you point that out to me?

    Thanks beforehand, and sorry for sounding like a noob (I am)

    1. Hey

      If i remember well, should be:
      1. Open shell
      2. Use command:
      sudo /pentest/wireless/gerix-wifi-cracker-ng/gerix-wifi-cracker-ng/
      3. Enter your user password

      that should be it 🙂

      1. No worries, I figured it out. It’s written in python, so i had to open it with sudo python /pentest …

      2. You usually do this from the menu. Example in ubuntu it’s in the “Applications” menu on the top right, then accessories, then “Terminal”

        shell = terminal 🙂

  2. Hello

    Cheers David for the idea,I have struggled with BT (on a tripleboot netbook !) for a while now due to lack/errors in drivers/support/window sizes and the like.Whereas my Ubuntu distros has been rock solid.

    Including BT rep in Ubuntu sources.lst some installs do fail cos they are looking for BT folders/dirs,simply expand the ‘details’ when it fails and correct the issue (as with the above example).I have now included many of my fav BT apps into Ubuntu-hurrah

    To launch, on desktop,do right click,create launcher,browse to and add as target,click the ‘spring’ icon and replace with the gerix.png from the same folder as application.This launcher can then be transferred into one of ur menus

    No wonder u had so much traffic to this one David…..
