While the license agreement states that this is only an evaluation copy which will expire after 30 days, we have a site license for ssh which you will install later. After accepting the terms, you will be asked for the destination directory and folder. You should reboot your machine in order to make sure everything has been activated. Select the license.dat file you downloaded. When you start ssh, the text will come up grey to indicate that no connection has been made.
Press enter or space to bring up the connection window.
Note that the connection window asks for the remote host and username, not the username and password. A separate window will pop up to ask for the password once the connection has been established. If you are connecting to a host for the first time, ssh will ask if you want to register a new encryption key for this machine into the database. Saving the new key will keep this dialog from popping up later. If you are connecting to a host which only has only ssh1 support, it will warn you, but it will make a secure connection using ssh1.
