Connecting to a Remote Host Computer
To connect to a remote host computer, click the Connect
icon on the toolbar, select the Connect option from
the File menu, or just hit Enter or Space on the
keyboard when the (still disconnected) client window is active. This
brings up the Connect to Remote Host dialog.
When you connect to a remote host computer for the first time, the host
will provide your local computer with a host public key. The
host key is the public key for identifying the
remote host computer that you're connecting to.
This process will bring up the Host Identification dialog.
