Re: WiFi and Bluetooth device detection

@Drew: Do you have any tips on which type / brand of wifi dongle I should go for? I admittedly know too little about wireless network technology (I'm a software guy). If you have any references to an article / post that outlines how to use kismet for this purpose, that'd be great as well. For Kisme...

Re: WiFi and Bluetooth device detection

Kismet is powerful, if you need help with setup I may be able to help a little :) It may make more sense to run a kismet server on another machine & have the Pi as a drone. It really depends on what you are aiming to achieve. I think bluelog is also installed in Kali linux (or is in the Kali reposit...

Re: WiFi and Bluetooth device detection

Ever heard of kismet? http://kismetwireless.net It is capable of passively monitoring wifi & logs to files you can use elsewhere. It's often found pre-installed in security/ pentesting distributions, Kali linux has a version for the RPi http://www.kali.org/downloads it should have kismet & the corre...

Re: Fried Pi - Component testing power issues

Most Pi setups aren't connected to earth. This means that the GND of the Pi can carry a voltage relative to earth. If you connect one of the gpio pins with your hand, you can connect it to earth like that. Due to that you can introduce voltages on the Pi that can fry the SOC gpio pins. As a result,...

Fried Pi - Component testing power issues

Hi, I have a Pi that will not show any signs of life. It was working for a long time but now it won't show any LED activity at all. It's a model B, rev 1. I actually have 2 boards the same (about a year old) and the other one is fine with all my power supplies & peripherals. It's not the SD card, I'...

Re: Raspbmc Airplay Issues [LAPTOP TETHERING]

You could try, just make sure you can login to the Pi & change it back without using ssh, because that will break if networking is setup incorrectly. If it is really slow to boot with a static IP remove the network cable. If you are lucky the laptop will actually route the MDNS packets to the other ...

Re: Raspbmc Airplay Issues [LAPTOP TETHERING]

I don't know what the 'web sharing trick' is, my guess that it is internet sharing? This will route internet bound traffic but it may not do multicast data. The Airplay service is a MDNS or Bonjour service that is broadcast via routers to all clients on a subnet. I'd guess that the internet sharing ...

Re: Mount MAC OS for rapsberry

Do you mean mount disks or run the OS?

You can mount Mac volumes if you install the appropriate tools, and you can mount Mac share points (AFP, NFS or SMB etc) with other tools but actually running the OS, as Spid mentioned, it won't work.

If you drive an led straight from the GPIO pin you will most likely damage the PI or the LED will go bang.

One of the best things about a Pi is that you can install stuff & break it without worrying about your data and OS.
