Remote desktop sharing allows remote users to view and optionally
control the desktop of the current user. The remote user needs to be sent
an invitation, and it is possible to create a password protected standing
invitation. This is ideal for tech support teams or administrators to gain
access to users desktops in order to troubleshoot or remedy a problem or
guide a user through a procedure.
Remote desktop sharing involves two applications: Desktop Sharing (KDE remote
frame buffer, a VNC server) and Remote Desktop Connection (KDE remote desktop connection; a
Desktop Sharing can be used by any user to create and manage invitations.
Invitations create a one time password that allows the recipient to connect
to your desktop. By default it is valid for only one successful connection,
and expires after one hour if not used.
Incoming connections are handled by the kinetd kded module. You can
use the command
to see if it is running. Desktop Sharing waits for connections
on port 5900 by default. When an incoming connection is made, a dialog will
appear to ask for confirmation by the current user.
