Aircrack-ng Suite and Dreamplug

Dreamplug Development Kit and Aircrack-ng

Dreamplug is development kit computer from GlobalScale Technologies that is based on the Plug Computer program.

“A plug computer is a small form factor server, intended to provide network-based services within the home. Built on a Marvell system-on-chip, the Marvell plug computer enables high-performance, always-on, always-connected, and environmentally-friendly computing that is readily available for developers. Unlike other embedded devices in the home it contains a gigahertz- class processor designed to offer PC-class performance.

The plug computer is suitable for file sharing, running a media server, back-up services, and remote access functions. It can be used as a bridge between home computing devices and Internet-based services. Plug computing is quickly expanding—delivering new devices, services, value-added applications, and advanced network connectivity to users.”

I discovered this device while looking an alternative to buying a Raspberry Pi development board. The Dreamplug is priced higher than the $35 Raspberry Pi but is a full kit unlike the Raspberry Pi solution which I believe is just the board and power supply.

Dreamplug Specifications

The Dreamplug is a complete development kit for under $200.

Dreamplug’s Unique Removable Power Adapter

If you remove the power power adapter from the Dreamplug body it looks like it isn’t much bigger than the Raspberry Pi board.

Getting Aircrack-ng Running on Dreamplug

Dreamplug ships with a Debian Linux / Ubuntu 9.1 and getting Aircrack-ng installed is very easy. Below are the steps I took.

  1. Plug Dreamplug into a power socket and the bottom wired interface into your network. By default the device starts the embedded WiFi card in open access point mode and has DHCP enabled. The default SSID is in the format dream-uAP-XXXX. XXXX is the last four characters of the WiFi cards MAC address
  2. If you are not able to figure out the devices ethernet IP address from your DHCP server you can connect the device’s access point and then SSH to 192.168.1.1. The default password for the root account is nosoup4u. Below is partial output of ifconfig command from my device. There are ways to convert the device into a router but it is much easier to just connect back to your wired/wireless network and SSH to the ethernet address of the Dreamplug (shown in bold text below).

    inet addr:172.16.12.58 Bcast:172.16.12.255 Mask:255.255.255.0

    RX bytes:22074375 (21.0 MiB) TX bytes:4114480 (3.9 MiB)

  3. Use command apt-get install aircrack-ng to download and install the suite.

    dreamplug-debian:/#

  4. Run airmon-ng to see if the wireless card supports monitoring mode. The output should look like below indicating that the embedded AzureWave card does not supporting monitoring mode. It may work but I didn’t bother tinkering with it. Instead I plugged in a Netgear WG111v2 USB adapter I knew would work in monitoring mode.
    dreamplug-debian:~# airmon-ng
    
    Interface	Chipset		Driver
    mlan0		Unknown		Unknown (MONITOR MODE NOT SUPPORTED)
    uap0		Unknown		Unknown (MONITOR MODE NOT SUPPORTED)

    Below is a photo of my unit plugged into a power strip under my desk with a Netgear WG111v2 USB adapter.

    After plugging in the USB card the output of airmen-ng is below.

    dreamplug-debian:~# airmon-ng

    Interface Chipset Driver

    mlan0 Unknown Unknown (MONITOR MODE NOT SUPPORTED)
    uap0 Unknown Unknown (MONITOR MODE NOT SUPPORTED)
    wlan0 Realtek 8187L rtl8187 - [phy0]

  5. Use wlan0 for airmon-ng by typing airmon-ng start wlan0 and then airodump-ng wlan0
