I have a network of 3 PC's in my house: two are desktop PC's that are hard-wired to the router, the other being a netbook that is wireless. I also have 3 Android tablets that are wireless. I want to use a tablet to connect to my Ubuntu PC to perform terminal commands (the other PC's are Windows-based, so they're irrelevant).
I have tried TeamViewer, PocketCloud, and Splashtop, but all of these require things to be installed on my local machine, and I would like to avoid that if at all possible. I have searched Google for SSH, but I am not quite adept enough to figure out how to use it.
