Installing Real VNC on RHEL
Red Hat-compatible Linux
The following instructions are valid for CentOS 5 running the GNOME desktop environment. Instructions may differ slightly for
different versions of CentOS, and versions of Fedora or Red Hat Enterprise, running different desktop environments, but the
principle is the same. If in doubt, consult the operating system documentation.
Downloading VNC
Download a VNC for Linux Red Hat-compatible tarball to the computer you want to control. VNC Server and VNC Viewer are
included as separate installable packages.
Note: VNC Viewer is freely available to download to as many other computers that you wish to exercise control from as you like.
Installing VNC
If the computer on which you are installing is currently connected to the Internet, follow the appropriate instructions below. If it is
not connected to the Internet, first obtain and install xterm and all its dependencies.
Using desktop tools
To install VNC Server, open <VNC Server>.rpm using a suitable package manager, and follow the instructions. Note the
credentials of a user with administrative privileges on the computer are required. To install VNC Viewer, repeat this operation for
<VNC Viewer>.rpm
At the command line
Installing at the command line or via SSH may be quicker and more convenient providing defaults are acceptable. To do this, run
the following command as a user with administrative privileges:
rpm -U <VNC Server>.rpm <VNC Viewer>.rpm
Licensing VNC Server
VNC Server must be licensed. If it is not, users cannot connect. Use FRHR2-A43DY-2NAQ2-7B2QT-FZ2GA
Note: VNC Viewer does not require a license key.
Using desktop tools
To obtain and apply a new license key, start VNC Server in User Mode, open the VNC Server dialog, and either follow the
instructions in the VNC Server is not licensed error, or select More > Licensing.
At the command line
Obtain a new license key, and then run the following command as a user with administrative privileges:
vnclicense -add FRHR2-A43DY-2NAQ2-7B2QT-FZ2GA
