11.2.3. Installing in VNC Connect Mode

VNC connect mode is when the system being installed initiates a connection to the VNC viewer running on a remote system. Before you start, make sure the remote system is configured to accept incoming connection on the port you want to use for VNC. The exact way to make sure the connection will not be blocked depends on your network and on your workstation's configuration. Information about configuring the firewall in Fedora is available in the Fedora Security Guide, available at
Procedure 11.2. Starting VNC in Connect Mode
  1. Start the VNC viewer on the client system in listening mode. For example, on Fedora using TigerVNC, execute the following command:
    $ vncviewer -listen PORT
    Replace PORT with the port number you want to use for the connection.
    The terminal will display a message similar to the following example:

    main:        Listening on port 5901

    When this message is displayed, the VNC viewer is ready and waiting for an incoming connection from the installation system.
  2. Boot the installation system and wait for the boot menu to appear. In the menu, edit boot options (see Section 4.2, “The Boot Menu”) and append the following options to the end of the command line:
    inst.vnc inst.vncconnect=HOST:PORT
    Replace HOST with the IP address of the system running the listening VNC viewer, and PORT with the port number that the VNC viewer is listening on.
  3. Start the installation. The system will initialize the installation program and start the necessary services. Once the initialization is finished, Anaconda will attempt to connect to the IP address and port you provided in the previous step.
    When the connection is successfully established, a new window will open on the system running the VNC viewer, displaying the installation menu. This window will provide full remote access to the installer until the installation finishes and the system reboots for the first time.
You can then proceed with Chapter 5, Installing Using Anaconda.
