Ssh opens a connection to remote_host and logs you in. The option -f  
puts ssh into the background allowing to launch an X client. This one  
is emacsclient, which is asked to evaluate some Lisp. This Lisp code  
is make-frame-on-display, which makes GNU Emacs open (create) a new  
frame on the specified screen as given by the environment variable  
DISPLAY. On the remote host DISPLAY should point to your local screen  
and its X server. So the remote GNU Emacs daemon or server will open  
a frame as an X client of your local display's X server and  
communicate with it via the SSH tunnel.


If this does not work you can start to debug ssh, but particularly  
allow (trusted) X11 forwarding in the configuration of the SSH server  
on the remote host. Your local X server must be informed to accept  
connections from the remote host.
