I am going to show you show you how I use SSH to log into a Linux server from macOS. I am going to use my Pair Networks shared host as an example. I like having shell access to my web host, which is one of the great features that Pair offers. In addition to SSH, you can also use scp to transfer files. Once you have set up SSH, scp should work automatically if you so desire to use it. By setup, I mean being able to log in to the server without having to enter a password every time.
