Backtrack How to

This is an collection of problems and bugs I had with Backtrack 5 R2 (Linux based Distribution).

To download Backtrack look at


Ubuntu software centre and update manager

For more Software, I installed the ubuntu software centre with this command:

sudo apt-get install software-center

then run a update:

sudo apt-get update && apt-get dist-upgrade

now you could choose your software sources at:

System > Administration > Software Sources

If you want the Update manager, run this:

sudo apt-get install update-manager

Or you could add the ubuntu repository to your system, just open the “/etc/apt/sources.list” file and generate a list from, now you could add what you want.


NVIDIA or ATI/AMD driver


just run it from your download folder.



sudo sh --buildpkg Ubuntu/lucid
sudo dpkg -i fglrx*.deb
sudo aticonfig --initial -f

After a reboot you could check your driver status with:




If you need more features at your network just install what you need:

network-manager-openvpn-gnome – Network Management framework (OpenVPN plugin GNOME GUI)
network-manager-pptp – network management framework (PPTP plugin)
network-manager-pptp-gnome – network management framework (PPTP plugin)
network-manager-vpnc – network management framework (VPNC plugin core)
network-manager-vpnc-gnome – network management framework (VPNC plugin GNOME GUI)
network-manager – network management framework daemon
network-manager-dev – network management framework (development files)
network-manager-gnome – network management framework (GNOME frontend)

sudo apt-get install network-manager-openvpn
sudo apt-get install network-manager-openvpn-gnome
