Some computers come with one or both parts of SSH already installed. SSH has two components: the command you use on your local machine to start a connection, and a server to accept incoming connection requests. Activate SSH on each hostįor two computers to be connected over SSH, each host must have SSH installed. Now that the terminology is settled, you can begin. Remote: A remote computer is one you're not physically in front of nor physically using.Every computer refers to itself as localhost, for example. Local: The local computer is the one you or some software is using.You might not think of your laptop as a "host," but you're likely running some service that's useful to you, your mobile, or some other computer. In IT, computers are called a host because technically any computer can host an application that's useful to some other computer. The term implies (but does not insist) that it's software without a graphical interface. For instance, a web server hosts a web-sharing service. Service: A service is software that runs in the background so it can be used by computers other than the one it's installed on.The IT community has well-established terms to help clarify descriptions of the process of networking computers together. When discussing more than one computer, it can be confusing to identify one from the other.

This article explains how to configure two computers for secure shell (SSH) connections, and how to securely connect from one to the other without a password. It's a daily task for many Linux users, but it can be confusing for someone who has yet to try it.
Thanks to OpenSSH, POSIX users can open a secure shell on any computer they have permission to access and use it from a remote location. One of Linux's most appealing features is the ability to skillfully use a computer with nothing but commands entered into the keyboard-and better yet, to be able to do that on computers anywhere in the world.
