SSH provides a secure channel over an unsecured network in a client-server 
architecture, connecting an SSH client application with an SSH server. Common 
applications include remote command-line login and remote command execution, 
but any network service can be secured with SSH. The protocol specification 
distinguishes between two major versions, referred to as SSH-1 and SSH-2.
