I have always wanted to use ssh on my network, but was too intimidated. Finally got around to it and it was much easier than I thought. The video begins with me SSHing on my laptop to the desktop. I call it my mother-ship because its where the devices are located but my computing is from the laptop. As you can see its quite easy SSHing on to my desktop.
Lets say I am computing on my laptop but want to play music through my desktop speakers. Sure I could get up, walk 10 feet, but I am comfortable where I am sitting. The SShing worked as planned, the Rhythmbox on my desktop opened on my laptop with all my music. Now all I have to do is selct play, pretty cool.
