15) in order to identify
the areas of the display that have changed, and then present that information to
remote VNC displays. These programs are similar to the x0vncserver program provided
by RealVNC, and produce an effect similar to the VNC servers used on Windows
and Macintosh systems where the only desktop display is shared to a remote
user.
The KDE desktop sharing tool is named KRfb and is configured through the KDE
Control Center; it??™s under Internet & Network ??? Desktop Sharing. The configuration
dialog is shown in Figure 14-2.
KRfb can be used in two ways: through invitations, which are temporary passwords
valid for one hour, and by allowing uninvited connections, which act like normal
VNC connections and may optionally be password-protected.
To manage invited connections, click on the Create & Manage Invitations button;
you will be shown the current invitations and given options for creating new invitations,
creating and emailing them, and deleting them. The invitation system is ideal
for some support applications when you want to permit temporary remote access.

If the ???Allow uninvited connections??? checkbox is selected, users will be able to connect
without one of the temporary passwords generated by the invitation system.
