SSH is, by design, a fairly secure means of gaining shell access to remote machines. However, there are always ways to eke out a bit more security and privacy from these connections.
One such method is with the help of Tor. With Tor, you can add a level of anonymity and even hide your services from prying/hacking eyes.
I’m going to walk you through the process of making SSH connections over Tor. The process isn’t terribly difficult so anyone that administers SSH should be able to make this work.
