# need to set a VNC password run 'man vncpasswd' to see how # as my 'myusername' (adjust this to your own). # Uncomment the lines below to start a VNC server on display :2 # The VNCSERVERS variable is a list of display:user pairs. The user names match actual accounts on the server as well, again I've cleaned this up below. My /etc/sysconfig/vncservers configuration is per below. I've tried a few suggestions I have seen around the internet including unsetting DBUS_SESSION_BUS_ADDRESS, killing all vnc processes and restarting and the suggested xstartup file for the user I'm testing with above from the RHN documentation. The client itself generally gives me a blank error message apart from the generic "connection failed". I've taken the IP address out of the above. SConnection: Client needs protocol version 3.8 When I attempt to connect I receive the following in the users log file: SELinux is disabled, the necessary ports are open (5900-5904) and four users are set up including vnc passwords.

I've also installed the VNC server from the repository and am having trouble getting connections to work from any of the various VNC viewers (UltraVNC, TightVNC and even TigerVNC) from my Windows 7 client PC. I've installed a new server with RHEL 6.4 and updated all packages using yum.
