Start the F-Secure SSH Client from the Windows Start menu under Programs > F-Secure SSH Client. To connect to a remote computer, follow these steps:
When you start F-Secure SSH Client, the Connection dialog box will open automatically. Type the name or IP address of the host you want to connect to, and your user name on the remote host. If you know that the SSH server uses a port other than the default 22, change the port number to that. Add an Authentication Method by clicking on the New button as shown in the picture below. You can add any of the three methods available, which are Password, Public Key and SecurID. You can change the order in which the different methods are tried by selecting a method with your mouse and moving it up or down on the list by clicking on the up and down arrows.

After giving the required information, click OK.
The first time you connect to a particular host, the following message will be displayed.

If you click Yes, the host key will be added to the local host key database for future reference and you will be connected to the host. If you click No, the host key will not be saved, but you will still be connected to the host. Clicking Cancel will not save the host key, and will cancel the connection to the host.
You will now be connected to the remote server, as long as the information you have provided is correct and the host you are connecting to supports SSH.
