WAN-Analytics-IoT

Tested on:

  • Raspberry-PI 2 Model B

  • OS Raspberrian "uname -a": Linux raspberrypi 3.18.7-v7+ #755 SMP PREEMPT Thu Feb 12 17:20:48 GMT 2015 armv7l GNU/Linux

  • Monitoring WLAN card chipset: Realtek RT5370

    • Note: the edimax dongle does not work on monitoring mode

Raspberry PI - Setup

$ sudo apt-get update
$ sudo apt-get -y upgrade
$ sudo apt-get -y install libssl-dev libnl-dev
$ wget http://download.aircrack-ng.org/aircrack-ng-1.2-rc2.tar.gz
$ cd aircrack-ng-1.2-rc2/
$ make
$ sudo make install
$ sudo apt-get -y install iw ethtool tshark

Avoid random network disconnections

$ cd /home/pi/WifiAnalyticsIoT/client
$ nohup ./network_reconnect.sh &

NOTE: Testing a different solution…​ it seems adding "wireless-power off" on the device listing at /etc/network/interfaces does the trick. Need to test longer term. Example config for wlan0:

auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
wireless-power off

Put the network in monitoring mode (assumes the monitoring enabled network card is wlan1)

$ ./startMonitor.sh

Test tshark (assumes the monitoring enabled network card is wlan1)

$ sudo tshark -i wlan1mon -I -l -f broadcast -R wlan.fc.subtype==4 -T fields -e wlan.sa -e radiotap.dbm_antsignal -e radiotap.channel.freq

tshark: Lua: Error during loading:
 [string "/usr/share/wireshark/init.lua"]:45: dofile has been disabled
Running as user "root" and group "root". This could be dangerous.

(leave it for a few minutes, enable and disable your cell wifi within a few meters range until you see some data being captured, but if you see "Capturing on wlan1mon" it should be good)

Config client

$ vi IoT-Analytics-Http/src/main/resources/application.properties

  • Change the serverUrl property with the Spring XD HTTP deployed stream location

  • Select the right tshark_process variable, depending on your environment

  • Save file

Start the client

TODO: change to generate Jar and run jar in background

$ cd IoT-Analytics-Http
$ ./gradlew run

Start the client process

./startClient.sh
