                This is a simple do-nothing, sleep-forever program that can be used as a 
                login shell (in Linux or Unix) to keep the connection open but without 
                interactive shell. We use it to create SSH accounts for users who will only 
                use them for SSH-tunneling; to create an encrypted tunnel to our servers 
                (for example to connect securely to database servers like mySQL, PostgreSQL, 
                etc).

                Most restricted shells still allow execution of local commands from the SSH 
                account. Setting the account shell to something like /bin/false (or any other 
                simple programs) usually won't work because the tunnel is closed as soon as 
                the program finish its execution. Sleep Dummy Shell just sleeps until its 
                execution is terminated by the user or the tunnel is closed.
