Unofficial training at Circle City Con

I’ll be presenting at Circle City Con this year, on Wireless Intrusion Detection with the Raspberry Pi. I’ve done  some test runs of the talk, and have ended with people wanting to contact me later if they have questions. Mainly if they get stuck. Also one of the comments from the reviewers when I submitted my talk was this would be better as a training class.

After talking to one of the organizers, here is how this is going to work. Currently I’m scheduled to talk on Saturday. After my talk, through the end of the Conference I can be available (as long as I’m not in a training sessions) to use some of the the common / lobby area to work with people wanting to set up the wireless drones, what kismet calls sensors.

Real-Time Rogue Wireless Access Point Detection with the Raspberry Pi

So I mentioned this previously as a teaser, but I had an article posted in the Linux Journal. It was based off my independent study at Eastern Michigan University.

It was in the December issue of the Linux Journal. Now it’s posted on their website.

This is related to the talk I am submitting for conferences this year. It has already be accepted to one conference. The talk has a little more information built in to it. For example the experience I had in an environment with heavy wifi coverage compared to home and Eastern Michigan University. A slight design modification. I don’t know yet if I’m going to rebuild using Raspberry Pi B+ or the new Raspberry Pi 2 model B.

Raspberry Pi projects

Back in May and June, I did a project for school with 6 Raspberry Pis to build a WIDs. It went good. I wrote an article, I’m waiting to hear back if it’ll get published.

After the project, I had 6 Raspberry Pis kicking around. I have a project I want to work on, that could lead to another article. I just need to build my skills up to that first.

To get there, I wanted to build an Onion Pi. This will tie in to another project I’m working on. As some of you know I’m a fan of The Onion Router (TOR), especially when I’m doing Intelligence related research. The Onion Pi would be a good thing to have in the bag of tricks.

To get the Onion Pi working, I needed to go through the Adafruit Wifi Access Point. This is the second time I build an AP. This one is just a little different than last time. This time instead of an Edimax wireless card, I went with one of my TP Link TL-WN722Ns. I wanted the external antenna. I was using the 2014-09-09_wheezy_raspbian image.

Hostapd didn’t work right. It kept throwing errors on start about nl80211 not being a known driver. I had to build hostapd from source, which needed to have libssl-dev and libnl-1.1 installed, to get hostpad to build right. Then I needed to copy my built version into the right place.

I also had problems with isc-dhcp-server and tor starting. It looks like wlan0 isn’t starting properly. I’ll have to troubleshoot it more later. Adafruit has a comment about disabling wpa_supplicant. I don’t know if that will fix the problem though. I’ll follow up after.
