Make certain that you have forwarded the correct port(s), or the range 5901 through 5909.* Add -localhost to options if you are connecting through a ssh tunnel or only locally. More secure* Run vncpasswd for each user in VNCSERVERS= list; this performs the initial user setup.* Start and stop vncserver to initialize vnc for each configured user service vncserver start service vncserver stop* Edit /home/username/.vnc/xstartup and change the end of the file: twm &To: exec gnome-session &* Now finally start vncserver for real! service vncserver start* Run your VNC Client and enter hda:1 as the host/IP address. You should now see your HDA Desktop screenThis adds some security.
