davidrumsjb:
How would that be inside the arduino code? All inside client.println(); ?
No, what sonyyu tried to instruct you to do is how to use the nano text editor on the Linino side to create the html file, so not quite what you asked for.
But then it begs the question why you are trying to do this from the AVR side of the Yun in the first place...
