4.1.39. /etc/sysconfig/vncservers
The /etc/sysconfig/vncservers file configures the way the Virtual Network Computing (VNC) server starts up.
VNC is a remote display system which allows users to view the desktop environment not only on the machine where it is running but across different networks on a variety of architectures.
It may contain the following:
VNCSERVERS=<value>, where <value> is set to something like "1:fred", to indicate that a VNC server should be started for user fred on display :1. User fred must have set a VNC password using the vncpasswd command before attempting to connect to the remote VNC server.
Note that when using a VNC server, communication with it is unencrypted and it should not be used on an untrusted network. For specific instructions concerning the use of SSH to secure VNC communication, read the information found online at http://www.uk.research.att.com/archive/vnc/sshvnc.html. To find out more about SSH, refer to Chapter 20, SSH Protocol in the Red Hat Enterprise Linux System Administration Guide.
