28.2.2. Connecting the Installation System to a VNC Listener

To have the installation system automatically connect to a VNC client, first start the client in listening mode. On Red Hat Enterprise Linux systems, use the -listen option to run vncviewer as a listener. In a terminal window, enter the command: 
vncviewer -listen

Note

By default, vncviewer uses TCP port 5500 when in listening mode. The firewall must be configured to permit connections to this port from other systems. Choose System → Administration → Firewall. Select Other ports, and Add. Enter 5500 in the Port(s) field, and specify tcp as the Protocol.
Once the listening client is active, start the installation system and set the VNC options at the boot: prompt. In addition to vnc and vncpassword options, use the vncconnect option to specify the name or IP address of the system that has the listening client. To specify the TCP port for the listener, add a colon and the port number to the name of the system.
For example, to connect to a VNC client on the system desktop.mydomain.com on the port 5500, enter the following at the boot: prompt: 
linux vnc vncpassword=qwerty vncconnect=desktop.mydomain.com:5500
