Starting with the current Xvnc4, there is a helper app available: vncconfig
pdw@zipper:~$ man -P cat vncconfig
vncconfig(1) Virtual Network Computing vncconfig(1)
NAME
vncconfig - configure and control a VNC server
SYNOPSIS
vncconfig [parameters]
vncconfig [parameters] -connect host[:port]
vncconfig [parameters] -disconnect
vncconfig [parameters] [-set] Xvnc-param=value ...
vncconfig [parameters] -list
vncconfig [parameters] -get Xvnc-param
vncconfig [parameters] -desc Xvnc-param
DESCRIPTION
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 avail‐
able from this window). The -nowin flag can be used if you always want
clipboard support but don't wish to clutter the desktop with this win‐
dow - 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 appropriate 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.
OPTIONS
-connect host[:port]
Tells an Xvnc server to make a "reverse" connection to a listen‐
ing VNC viewer (normally 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 listening on
the default port of 5500, you can specify host:port instead.
-disconnect
This causes Xvnc to disconnect from all viewers so that the VNC
desktop is not displayed anywhere.
[-set] Xvnc-param=value
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 effect.
-list Lists all the parameters supported by Xvnc.
-get Xvnc-param
Prints the current value of the given Xvnc parameter.
-desc Xvnc-param
Prints a short description of the given Xvnc parameter.
PARAMETERS
vncconfig also has parameters of its own which can be set on the com‐
mand 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. Parame‐
ters 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.
-display Xdisplay
Specifies the Xvnc server to control.
-nowin When run as a "helper" app, don't put up a window.
-iconic
When run as a "helper" app, make the window iconified at
startup.
