Category Archives: Conference Appearence

One of the differences between college and real life (bias in speaking)

Last talk I have, I expected audience participation, because I asked for it. I failed the audience. I know how to improve the talk for last time.

What was my bias that lead to me failing the audience? I’m used to participation being part of my grade, and having to participate. Others in classes were the same way. Yes we had some that barely participated. But usually half the class did.

Because that’s what I was used to in college class setting, that’s what I expected at a conference talk. The result was I failed my audience with expectations that I shouldn’t have put on them.

Rough Outline for Circle City Con

Just so people have an idea of what the class is going to cover:

1. Basic theory of electromagnetic radiation known as radio waves
2. Install SDR# software and configure Dongle on Windows to monitor broadcasts (FM radio, Ham Radio, Other bands).
3. ADBS (Track airplanes, basically how FlightAware does it, with remote sensors people run)
4. Frequency counting (finding what Freqs are popular in an area to do more of item 2).
5. Radio Directional Finding, using RTL-SDR dongles on a Raspberry Pi with a touchscreen and gui software.
5a. (for licensed HAMS) how to turn the Raspberry Pi in to a broadcasting radio

RTL-SDR for Circle City Con

Remember I said you only need 1 of these. These are how they came from Amazon (where I got them all), see last post for links. Again I like this because it’s a metal case and came with 2 antenna.








The NooElec in the aluminum case. This is a bare USB stick put in to the block. The picture on Amazon is blue, but what I got was black with silver lettering (I like that look).





The Blue NooElec, like the one in the block case, it comes with a telescoping antenna.






Lastly the NooElec cheap option, with the stick antenna, that doesn’t collapse.

New and Improved WiFi Intrusion Detection System. Pi 2.

So my last post I was fighting the Raspberry Pi 2, with Kali Linux 2.0.1, when it came to starting kistmet_drone on boot. Ian had a work around, but it wasn’t what I wanted. I wanted the built in tools to do their job. Well it turns out it’s a SystemD problem. I spent probably about 12 hours bashing my head against it, making changes and trying things.

Finally, I got smart with my Google searching, and found a slightly better way, but still didn’t want to call an external shell script. Then I spent time smacking my head on the desk. SSHD works, and starts by systemd, why not look at it’s config. Seriously the better you are at something, the less you think of the simple answers that made you good to start with.

2 new lines. One made SystemD wait until after networking was up. The second was a strange sshd -D option. man ssh. Oh doesn’t run ssh as a daemon…

remove –daemonize from Kismet… It worked.



Now to get everything ready before I leave for GrrCon in 17 hours, I’ll be presenting Saturday last I heard.

More on moving WIDS to the Raspberry Pi 2.

So I’m using the Raspberry Pi 2 and Kali 2 for this project so far. As I said last time, I had to expand the image to use the full disk. I have a script for that now. I was actually trying to script the whole deployment. These scrips can be found on my WIDS github repository. But fair warning they are still a work in process.

Moving WIDs to Raspi2.

So I tried to do this back in July but got sick. My next talk is at A2Y.asm on Sept 12, and rebuilding all the Pi2 again with Kali 2.0.1. I have litteraly spent most of the day trying to expand the root directory.

There is a tool called rpi-wiggle, that sounded really cool, but it hasn’t been updated in 3 years. It also didn’t work for the pi2 running Kali 2.0.1. After lots of searching, I found a forum post saying talking about it.

After running apt-get install triggerhappy lau5.1 (from Kali repos) and getting the Debian raspi-config file from Debian. It says it worked. I’m waiting for the reboot to know for sure.

And it worked. from console it says it has full space.

Now if I was making anything other than a drone, I’d run apt-get install kali-linux-full to get the whole Kali experience instead of the light version. But I’m making a drone. So here is what needs to be worked on before I start making images:

  • install: Kismet, NTP.
  • boot to cli instead of gui
  • change the root password
  • configure kismet
  • Clone
  • configure static ip, and daemon mode.

normally I’d disable ipv6, still might. but the ipv4 and ipv6 stacks are working well together right now. In the past they haven’t.

Updating talk

For Bsides, as mentioned earlier, I’m making some changes for the talk.

For Bsides Detroit I’m swapping out the original Raspberry Pi B devices from the project for the Raspberry Pi 2 B.

The first time I did this, with the RPi-B, I made one image got it working and then cloned it to the others. It caused minor problems with the wireless card naming. I also still had to touch them all to change names, static ip addresses, and the kismet configs.

This week there was a new version of Kali out for the Raspberry Pi 2 when I checked. So I downloaded it, patched it and installed the software. Then created the clone image.

I am going to have to touch each one anyway so figure I will just get the one image with the software, and then load each one and configure it.

Bsides Detroit 2015

The last schedule I have seen has me speaking at 4pm on Saturday the 18th at Bsides Detroit.

I know it’s a surprise to me to.

Talk is similar to the one I gave at Circle City Con on Raspberry Pi and Wifi detection.

New this talk: Looking at the clients, email alerts (I hope) and all on Raspberry Pi 2 (again I hope).
