From the man page for ssh:

     -f      Requests ssh to go to background just before command execution.  This is useful if ssh is going to ask 
             for passwords or passphrases, but the user wants it in the background.  This implies -n.  The recommended way 
             to start X11 programs at a remote site is with something like ssh -f host xterm.

             If the ExitOnForwardFailure configuration option is set to “yes”, then a client started with -f will wait 
             for all remote port forwards to be successfully established before placing itself in the background.
