These instructions describe how to test wireless networks for security holes and how to use the various security softwares with the XO OLPC. However, great care should be taken in using these tools and software as they may brick your XO in the worst case or considerably bloat your configuration. (Especially when saving large data files...)
Updating Your Software/Firmware
Check General Firmware
http://wiki.laptop.org/go/Firmware http://wiki.laptop.org/go/Upgrading_the_firmware
Check Wireless Firmware
Check that you have a recent version of the wireless firmware by following these instructions: http://wiki.laptop.org/go/Test_Config_Notes#Update_the_wireless_firmware
Check Software
In order to continue we need some network tools:
wireshark - kismet - aircrack-ng - nessus - bind-utils - Collection of utilities for querying name servers and looking up hosts. traceroute -
We can install all of these in one go (in the terminal application):
su yum install wireshark kismet aircrack-ng nessus bind-utils traceroute
yum install wireshark_gnome
Configuration of Network Tools
Performing the Analysis
Find a target network
Press the Mesh button and inspect any interesting access point (AP).
Check if the network has some form of security
If you can connect to the access point without any trouble, the network is not secured. Check the instructions at #Securing your network.
Collect Network data
Cracking a WEP key
Follow the instructions at this page: http://docs.lucidinteractive.ca/index.php/Cracking_WEP_and_WPA_Wireless_Networks
TODO: We should write a short distillation of that wiki here.
Cracking a WPA key
Execute the following command in the terminal application while there is a client succesfully connected to the wireless access point:
aireplay -0 5 -a <AP MAC> -c <Client MAC> ath0
Cracking a MESH network
