Bumbershoot, sorry about the IP addresses, its because I gave up on a raspberry pi that I had previously installed, installed a new one from scratch, hence the new ip address at 192.168.0.29. Everything ran smooth as far as I could tell via the scrip, and i'm able to ssh into it no problem. However, I don't believe Nodelink is running, and have no idea where to go next. Running your script gave this:
pi@raspberrypi:~ $ ps aux | grep Node
pi 1574 0.0 0.4 7332 1892 pts/0 S+ 17:40 0:00 grep --color=auto Node
