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.
