WPA2 broken?

WPA2 Hole196 Vulnerability
WPA2, perceived as the most solid Wi-Fi security protocol, is widely used by enterprises for securing their Wi-Fi networks. But security researchers at AirTight have uncovered a vulnerability called “Hole196″ in the WPA2 security protocol that exposes WPA2-secured Wi-Fi networks to malicious insiders. Exploiting the vulnerability, an insider can bypass WPA2 private key encryption and authentication to sniff and decrypt data from other authorized users as well as scan their Wi-Fi devices for vulnerabilities, install malware and possibly compromise those Wi-Fi devices. AirTight researcher, Md. Sohail Ahmad, will be demonstrating this vulnerability at the Black Hat Arsenal and at DEFCON18 in a presentation entitled “WPA Too?!” in Las Vegas on July 29th and July 31th respectively.

“There is a problem with the office database”

Close all Office products running
Create a temporary folder on your desktop
Move “Microsoft User Data” folder under Documents to the temp folder
Move all com.microsoft.* under ~/Library/Preferences to the temp folder
Move Microsoft folder under ~/Library/Preferences to temp folder
Open any Office application such as Word or Excel. This should take you through the registration process once more and clear the error.
Alix 3d3 scripts
by ac3bf1 on May.18, 2010, under Gadgets, Tutorials
Simple stats script:
#!/bin/bash clear while [ 1 ] do uptime df -h | grep Filesystem df -h | grep rootfs df -h | grep usb echo "" Temp1=$(cat /sys/bus/i2c/drivers/lm90/0-004c/temp1_input) Temp2=$(cat /sys/bus/i2c/drivers/lm90/0-004c/temp2_input) echo "MB T = "$Temp1 echo "CPU T = "$Temp2 sleep 1 clear done
Insert it in a file. I called it stats.sh
chmod a+x stats.sh
and run with ./stats.sh
It updates every second and returns:
- uptime with load
- Disk space and usb disk space
- MB temp
- CPU temp
You can add all you want in there or remove what you don’t need

First Mod: Heatsink with fan!
I noticed that my processor was going up to the 50′s plus degrees when working, so I decided to keep it cool by adding a Heatsing with a FAN. I found one on Amazon.co.uk, specifically designed for Graphics chips, so I thought it would be ok for my Alix. It came with a self-adhesive strip on the bottom which made installation simple. Then after seeing that an 18V supply for the Alix was too high, and hmm… I ran out of adequate resistors to step down the voltage… I hooked on the 5V supply right behind the Serial port! And that ensures i get minimal fan spin, and hence virtually no noise from the fan. The airflow is enough to cool down the heatsink, as there is a noticeable difference when the fan is operational and not.
Update: While compiling the kernel the cpu temperature stays below 42 degrees (Celsius)
Application:
I am now trying to develop a home-made GPS tracker with a GPRS modem to “report back” the location… More on this coming soon!

Volume by UUID and adding the disk to a xen Virtual Machine
by ac3bf1 on May.08, 2010, under Tutorials
Get the drive UUID by using the command vold_id
vol_id /dev/sda1
The string after “ID_FS_UUID=” is the UUID of the drive. Now open your /etc/fstab file and add the following line to the end. Replace the UUID string with your string, your mount point, and customize the other parameters if needed.
UUID=37153555-2c20-415f-88e4-4510d8e3859a /mnt/USBDrive ext3 user,auto,rw 0 0
To then pass a disk to a xen virtual machine, look at the following lines of the domain config file:
disk = [ #...root partition and other partitions here... 'phy:/dev/disk/by-uuid/89b976bc-2f66-4b93-abfb-358d6227f8be,sda,w', 'phy:/dev/disk/by-uuid/1871b9a1-8055-4392-8a94-f5407ff37483,sdb,w', ]
basically instead of passing the disk as a /dev/sda1 device, pass it by UUID using the path:
/dev/disk/by-uuid/<the uuid>
Enjoy!
