I have been following along with the Hak5 Fon stuff for a while and decided to make a complete package.
The main modifications are 2 neodymium hard drive magnets glued onto the back of the EEEpc screen and the base of the Fon, holding it nice and tight.
The Fon runs:
• OpenWRT
• Jasager v.2.
• Webif
Its in static IP mode so I can use the laptop as the default gateway, this wasn’t working with it set in DHCP mode.
The EEE runs:
• Windows XP (It was backtrack 3 until hamster and ferret)
• Hamster and ferret
• WireShark
• TFTPD
The Fon links to the EEE over Ethernet for data and the power adapter was cut and attached to an old USB cable to give 5v and 500mA
The antenna was bought of eBay for £16, just over $35.
The EEE runs TFTPD as the DHCP server and with the wifi and Ethernet bridged, it pipes through internets from whoever I am connected to.
There are a few problems that I need to address; I was looking for some help on expanding the project.
The problems so far are:
• The Ethernet occasionally drops out, this is most likely just my shoddy use the crimpers and should be easy enough to sort out.
• I am getting poor signal from the Fon, even with the much larger antenna. This may be caused by having less power to throw at the antenna. The USB can provide a maximum of 5V and 500mA the Fons original transformer produced 5V and 2000mA I wonder if it would be possible to cut off another USB cable and directly attach it into to wiring already established. I don’t know if this would create 10V with 1000mA however.
The low signal quality might also be to do with slightly damaged wires leading to the SMA connecter inside the Fon.
In the future I would like to add:
• Messenger sniffing capabilities
• Injection capabilities as simple as Aireplay’s
• UpsidedownTernet
• A little magnet on the antenna and the top of the EEE's screen, to replace the BluTack
Thanks for any help and guidance offered.
