A report back from Tuesday's hack sesh:

• We started off by installing Wireshark on our computers. Sae and Sarah run OS X 10.8 (Mountain Lion) which does not come with X11, so they needed to install XQuartz before launching Wireshark. (Sae, there you go, that's how you do it buddy.) We then dived in and played around with the basic features. (X11 is a cross-platform windowing system like Aqua and Cocoa are windowing systems for OS X. Lots of open source projects use it for their GUIs because it allows to code one solution for many platforms. The trade-off is the applications don't have the Apple/Windows look-and-feel that we all expect.)

• Using Wireshark is a bit like a scavenger hunt. There's a lot of information flowing on our local networks, the fun part is trying to figure out what is interesting. Robbie and Peter, connected to the standard NYU wireless network, started to capture packets with dynamic webpages streaming election updates. They saw a lot of web traffic racing in and out of their own comp

A little report back from tonight's hack sesh:

• Peter and Jonathan tried to hack into Peter's Netgear (I think it was a WNR1000) to flash OpenWrt. They weren't able to get the machine to respond to the flashing process, the Broadcom processor on that device doesn't appear to be so popular and there isn't much online community support for this product.

• Karl brought 3 old WRT54Gs and discovered one of them was already running OpenWrt! Awesome, a really old build from 2006. We thought about upgrading the firmware but it was password protected really well -- the admin password prompt even worked when doing a factory reset on the sucker.

• Johann, Sae, and Robbie played around with the OpenWrt interface and discovered how to blink the LEDs on the main page, how to SSH into the router, and thought about possible applications of an OpenWrt router. Johann and I were setting up a captive portal on the device to have it so every website accessed was redirected to the router's HTTP webserver.

Good stuff! We'll me

I'm testing out a setup in my lab but am having trouble configuring it correctly! I've tried a lot of variations of the setup, read the documentation, and went through the mailing list to see what I'm doing wrong, but can't figure it out.

I followed the sophisticated setup and added ethernet links to it, possibly in a wrong way. I read somewhere that ethernet interfaces must be added to batman as bridges. (Side note: this causes my dmesg output to complain about too small of MTU for the ethernet interfaces but I can't seem to raise the bridge MTU to 1528 like it suggests.)

Network diagram:

       wlan0 AP      br-mesh1 --- eth0
             \      /                 \

I'm going to make materials to publicize my thesis project, Outernet.

Outernet is a local wifi network that connects communities in Long Island City, Greenpoint, and Bushwick without using the Internet. People connected to Outernet will be able to participate in the classifieds, forums, and chat.

I want to let people know where they can connect to the network, and make posters to advertise the network.

Design ideas:

• Hobo code
• Stencils
