It is quite a powerful tool when you really delve deeply into it. I am hoping to share some of what I consider to be essential knowledge about the OpenSSH client as well as dispel some misunderstandings.
But every day, there is some new thing about it that we learn and there are plenty of people who know little about it. Any of us who are familiar with OpenSSH assume that everyone who wants to use it knows how to.
