I manage a couple of thousand linux servers. They all are located in the datacenter several floors below me. In order to manage any single one, I need to log in.
With SSH, I can do that from my desk, without ever having to actually go the physical server.
So this is not something that a plain user would find a real reason to use it, is that an accurate statement? Or is there a reason the average computer user would see a need for this knowledge? 8>)
In addition to PKI encrypted communications for login sessions there is the scp command which enables you to copy entire file hierarchies from one machine to others with a single command and the use of shell meta characters.
There is also the ability to create encrypted “tunnels” for data stream end points with ssh and so much more.
