Like its poorer cousin, the prime use of SSH is to log in securely to servers. SSH does not provide you with a login and password prompt as Telnet does. SSH participates in the user authentication process when the connection is being negotiated (you will see why later). Because of this, SSH needs to know the username you want to use to connect to the server before it attempts a connection. If you just use SSH to connect to a remote server, the SSH client will assume you want to connect to the server as your current userid (see Listing 15-10).
