/* An example of ne7ssh library usage. Please change the values in connectWitKeys 
   function before compiling.
   
   This will work with openssh server if default shell of authenticating user is bash.
   When using a different shell or custom prompt replace " $" string in waitFor() 
   method with a string corresponding with your shell prompt.
   
   If you are testing this with later openssh versions, make sure to add this
   option to your server's configuration file to enable password authentication:
   
   PasswordAuthentication yes
