TridiaVNC prerelease 1.3.2 provides support for AuthHosts
and QueryHosts.  By setting AuthHosts to "?", you can cause
an accept dialog to appear for all incoming connections.
Supportal members can access the 1.3.2 binaries immediately
from  In addition, the source code is
available on

We are also in the process of adding an optional beep on
connection and disconnection, as well as an option to accept
a connection when the accept dialog times out.

One problem with implementing an accept dialog on the Unix
platforms is that there is no one to accept the first
connection.  I suppose, one could enable the normal VNC port
when the "inetd" option is used and then only require the
accept dialog for connections on the regular port.  Another
option would be to only require the accept dialog for the
second and subsequent connections.  It is not immediately
clear to me how to handle the accept dialog in the Unix

If a regular XFree86 server had VNC support grafted onto it,
then an accept dialog for new connections would make more

Comments anyone?
