VNC 3.3.3r2 authenticationPanel text -- further definition

[MCALLISTER,RONAN (HP-FtCollins,ex1)]

Hello fellow VNC'ers!

I appreciate all of the feedback on this subject -- to restate my "wish", I
of course can currently "kill all clients" or prevent VNC connections but
what I really need to do is to simply provide some type of warning message
to the new connecting client.   It may be since I have asked specifically
for the authenticationPanel "MOTD" this is not as trivial as I thought (due
to my lack of understanding of the architecture), so if anyone has any
suggestions as to how to do this outside of VNC that would be greatly
appreciated.

I thought possibly one could monitor VNC ports on the VNC server side, then
provide a NT or X message box with the MOTD text.  If this was only NT I
guess it would be simple (for the person managing the VNC server) to
manually change the Windows desktop during this "testing" phase to have
wallpaper including the MOTD (or a dramatic color scheme indicating they
should read the MOTD file).  This would be a procedural method of
accomplishing the same thing.

And BTW is there a good freeware tool for looking at NT port and socket
connectinos -- like lsof?

Again just a note to let you know I appreciate your thoughts,

Like I understood Ronan he would like a text to be displayed before
authentication, so sending clipboard updates is not possible. If it's ok to
display the text after authentication, you could put some kind of proxy
(maybe
called vncmessage) between client and server that displays the text message
and
an OK button, and if the button got pressed, the proxy will forward to the
server.
