If this produces something like "vncviewer: command not found" then either you have yet to install a vncviewer OR (likely if you are using a Mac) you have neglected to make the vncviewer available in your PATH. To find out (once you have installed a VNC viewer of course) run: vncviewer -version. Linux computers may well have a vncviewer installed already, if not we advise installing either TigerVNC or RealVNCIt is sometimes useful to know the version of VNC you are running. Please see the comments at the beginning of the vnccli script (see below) for advice on how to install this. Mac OS X computers will have ssh installed already but will not have a vncviewer program: we advise installing TigerVNC.If this doesn't produce a second desktop in a window as just described, please enter: rm ~/.vnc/xstartup and try again.
