With the unlikely name of
vncconfig on Linux, you can get bidirectional cutbuffer/clipboard interaction.
From the manual entry of
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. The
vncconfig command puts up a window with some checkboxes which can be used to disable clipboard transfers if required. The
-nowin flag can be used if you always want clipboard support but don't wish to clutter the desktop with this window
-iconic option can be used to make it iconified by default.
DISPLAY environment variable or the
-display option will be used to identify the display/window in which to be active.
