A.2. Enabling Remote Access to the Installation System
You may access either graphical or text interfaces for the
installation system from any other system. Access to a text mode
telnet, which is installed by
default on Fedora systems. To remotely access the graphical display
of an installation system, use client software that supports the
VNC (Virtual Network Computing) display protocol. A number of
providers offer VNC clients for Microsoft Windows and Mac OS, as
well as UNIX-based systems.
|Installing a VNC Client on Fedora
Fedora includes vncviewer, the client
provided by the developers of VNC. To obtain
vncviewer, install the
The installation system supports two methods of establishing a VNC
connection. You may start the installation, and manually login to
the graphical display with a VNC client on another system.
Alternatively, you may configure the installation system to
automatically connect to a VNC client on the network that is
running in listening mode.
A.2.1. Enabling Remote Access with VNC
To enable remote graphical access to the installation system,
enter two options at the prompt:
linux vnc vncpassword=
vnc option enables the VNC service. The
vncpassword option sets a password for remote
access. The example shown above sets the password as
The VNC password must be at least six characters long.
Specify the language, keyboard layout and network settings for
the installation system with the screens that follow. You may
then access the graphical interface through a VNC client. The
installation system displays the correct connection setting for
the VNC client:
The VNC server is now running.
Please connect to computer.mydomain.com:1 to begin the install...
Starting graphical installation...
Press <enter> for a shell
You may then login to the installation system with a VNC client.
To run the vncviewer client on Fedora,
choose → → , or type the command
vncviewer in a terminal window. Enter
the server and display number in the VNC
Server dialog. For the example above, the
VNC Server is
A.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 Fedora systems, use the
-listen option to run
vncviewer as a listener. In a
terminal window, enter the command:
|Firewall Reconfiguration Required
By default, vncviewer uses TCP port
5500 when in listening mode. To permit connections to this
port from other systems, choose → → . Select
Other ports, and
in the Port(s) field, and specify
tcp as the
Once the listening client is active, start the installation
system and set the VNC options at the
prompt. In addition to
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
on the port 5500, enter the following at the
linux vnc vncpassword=
A.2.3. Enabling Remote Access with Telnet
To enable remote access to a text mode installation, use the
telnet option at the
linux text telnet
You may then connect to the installation system with the
telnet utility. The
command requires the name or IP address of the installation
|Telnet Access Requires No Password
To ensure the security of the installation process, only use
telnet option to install systems on
networks with restricted access.
