vncconfig is used to configure and control a running instance of Xvnc, or any other X
server with the VNC extension. Note that it cannot be used to control VNC servers prior
to version 4.
When run with no options, it runs as a kind of "helper" application for Xvnc. Its main
purpose when run in this mode is to support clipboard transfer to and from the VNC
viewer(s). Note that without a running instance of vncconfig there will be no clipboard
support. It puts up a window with some checkboxes which can be used to disable clipboard
transfers if required (in the future there may be more functions available from this win-
dow). The -nowin flag can be used if you always want clipboard support but don't wish to
clutter the desktop with this window - alternatively the -iconic option can be used to
make it iconified by default.
When run in any other mode, vncconfig is a one-shot program used to configure or control
Xvnc as appropriate. It can be used to tell Xvnc to connect or disconnect from listening
viewers, and to set and retrieve Xvnc's parameters.
Note that the DISPLAY environment variable or the -display option must be set as appropri-
ate to control Xvnc. If you run it on an ordinary X server (or on a version 3 Xvnc) you
will get an error message saying that there is no VNC extension.
Tells an Xvnc server to make a "reverse" connection to a listening VNC viewer (nor-
mally connections are made the other way round - the viewer connects to the
server). host is the host where the listening viewer is running. If it's not lis-
tening on the default port of 5500, you can specify host:port instead.
This causes Xvnc to disconnect from all viewers so that the VNC desktop is not dis-
Sets an Xvnc parameter to the given value. Note that some of Xvnc's parameters are
read only once at startup so that changing them in this way may not have any
-list Lists all the parameters supported by Xvnc.
Prints the current value of the given Xvnc parameter.
Prints a short description of the given Xvnc parameter.
vncconfig also has parameters of its own which can be set on the command line. These
should not be confused with Xvnc's parameters which are manipulated with the -set, -get,
-list and -desc options.
Parameters can be turned on with -param or off with -param=0. Parameters which take a
value can be specified as -param value. Other valid forms are param=value -param=value
--param=value. Parameter names are case-insensitive.
Specifies the Xvnc server to control.
-nowin When run as a "helper" app, don't put up a window.
When run as a "helper" app, make the window iconified at startup.

VNC was originally developed by the RealVNC team while at Olivetti Research Ltd / AT&T
Laboratories Cambridge. TightVNC additions were implemented by Constantin Kaplinsky. Many
other people participated in development, testing and support.
