11 dec 2001 Status report ----------------------------- A new project appeared in Kaboodle's workspace: VNCSession. It is a stand-alone exe-application that supports VNC tunneling. This is a next temporary solution, which allows for independence upon the Kaboodle internal threads and Kaboodle socket implementation: 1. VNC is extremely sensitive to gaps in data flow. Kaboodle apparently performs periodical network inquiries and screen updates in the main thread, which leads to execution delays and thus connection breaks or runtime errors in the VNC Viewer. To avoid this, VNC tunneling now uses its own connection rather then Kaboodle's native tube. 2. As it was discussed in the previous report, we use CSocket MFC class for both VNC-Kaboodle and Kaboodle-Kaboodle communications while Kaboodle uses CAsyncSocket MFC class for all connections. The idea of total retrofitting Kaboodle's sockets, I am afraid, must wait until later (may be when we implement SSL/SSH).
At present the user interface looks like this. You right-click _your_ computer and choose the VNC tab on the property panel. Then you click the "Listen:" button to start VNC server. You will get the VNCSession window. (It is a temporary solution and will definitely be eliminated in the release version). You must click the "Listen" button. At the other computer, you right-click the server that you have just launched and also go to the VNC tab. Then you click "Start Sessoin" and in the VNCSession window click "View". The session begins. The VNC operation is only stable until you open or close a window thus forcing a large region to be updated. Here you have a problem: the server unexpectedly closes connection. We believe it is due to a gap during data transfer. The registry keys values AllowLoopback and LoopbackOnly appeared really useful. We set them as follows: AllowLoopback = 1, LoopbackOnly = 0 - this proved to be the only combination that works. The VNCSession application reads the old values, stores them in Kaboodle's registry section and sets the new values as above. If the application has been aborted or abnormally terminated then the next time it runs the saved values are picked up, which guaranties the original settings are not lost. On exit, the saved values are restored. -Oleg _______________________________________________ Kaboodle-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/kaboodle-devel
