One of the main reasons I purchased an Arduino Yun as my first Arduino board was it’s inclusion of WiFi right out of the box. This means you can start making Internet of Things projects immediately. As I have introduced myself to Arduino, I have also looked to learn more about the Linux side of the Yun, how it bridges to the Arduino side and how I can interact with it using standard Internet tools, like SSH and FTP. An Arduino with SSH Once the Arduino Yun is connected to a network, it is possible to use the Macintosh Terminal or other SSH client to log into the Yun and use it as you would any Linux computer. You’ll need an SD Card on the Arduino Yun to do much with SSH or ftp access, though, as you need a place to store the files you will be uploading or creating. This is fine if you just want to view files on the SD Card or other basic terminal operations, but as I was playing around, I realized i wanted to do more than use the built-in vi editor. I use a Mac OS X text edit
