First off, GT Lawn automatically closes off connected devices from the external world (they can get out, but noone can get in). This is for security purposes and makes sense. However, if we need to connect to the Turtlebot via SSH, then it becomes a problem. There are two categories of solution to the problem.

• Contact OIT and insist that they open inbound services for your device/Turtlebot (really insist!)
• Disable inbound securiy service every time you connect to GT Lawn.

The first can only really done in limited quantities and by faculty (at least that's my belief given how much it took for me to get just one Turtlebot opened up like that). That means we'll be doing the second category here. Instead of connecting to GT-Wifi which we all love, we will have to connect to eithet GT-Other or GT-Device. GT-Other is the easier method.

Figure out what the special key is for GT-Other. It is on the [http://lawn.gatech.edu/|GT-Lawn] page as an option (“Pre-shared Key” link off to the left). Enter your credentials and get the secret password. Once you got it, you can connect to GT-Other, but the connection won't give you internet access. Open up a browser and navigate to [http://auth.lawn.gatech.edu | auth.lawn.gatech.edu]. You'll see a view like the one below:
