Presence detection

Working on detecting when my phone enters and leaves the Wildsong AP. Presence detection

Wardriving

Setting up a Raspberry Pi to do some wardriving (or warcycling or warwalking?) Will probably use an Alfa 802.11b/g/n adapter from Rokland.

• Horst = Highly Optimized Radio Scanner Tool = low footprint
• Kismet = been around longer, more features

Testing on Pi 4 Tenrec today with sudo iwlist wlan0 scan|grep SSID With the Alfa I see 35 stations. On the built in wlan0 I see 9. So, Alfa it is. The built in interface is dual band (2.4 and 5.8) but the Alfa is 2.4 only. I might want to replace the Alfa later but most access points advertise on both bands so I don't think it matters to me right now.

Quickie test: sudo iwlist wlan1 scan

Examine interfaces with

sudo iw dev
sudo iw phy phy0 info
sudo iw phy phy3 info 

Horst info:

• https://www.linuxlinks.com/horst-highly-optimized-radio-scanning-tool/
• https://netbeez.net/blog/remote-wifi-packet-capturing-with-horst-on-raspberry-pi-and-odroid/

To-do:

• Install and test Alfa (DONE)
• Install and test Horst. Done but need to know more about it; logging? GPS?
• Install and test Kismet on Pi 4
• hook up a GPS (in car: UBlox AEK-4P walking? I have a little chip GPS around)
• remove the Pi 4 from the 7" screen -or- go with a Pi 3 -or- even a Pi Zero?

Can I run this software on a Pi Zero? I just want to log data, nothing else. That would be Kali on Pi0W

I guess if I am going this route I best pull out the Pi Zero W now. The Pi 4 is a big mess all over the kitchen counter now anyway.

Kali

I tried installing Kismet on Raspbian and it failed, so I installed Kali.

Kali runs X11 by default so I disabled it with

systemctl disable lightdm

I would disable HDMI to save power but I am afraid I will need to connect the KVM up in the near future to get access when WiFi is not available.

Kismet

sudo -s
systemctl enable kismet
systemctl start kismet

Now go to a browser go to http://zebra:2501/ and set a username and password.

Okay, it ran for a good 15 minutes and I think it wants at least a Pi 3. Start again.
