Re: [Fwd: Re: managing multiple participants]
Original Message Hi there, When I start a vnc server enabling others to share the session using a common password, I would like to being able to switch between active and passive participants. I could imagine different modes of operation: 1) one active user - many observer 2) many active users (sending mouse/keyboard events) - many observer 3) all active users With a stock vnc installation, there is no way to do this that I am aware of. I am curious - are you running a Windows vnc server, where all participants see the same remote desktop? It's my understanding that with a *nix vnc server, each client gets their own desktop. We do run on Unix (SGI and/or Linux), but here the behaviour is the same: each client sees the same desktop. You can start multiple servers (with multiple desktops) though. I do not know about windows. If you are running a Windows server, in the many/all active user cases, do you want different participants' mouse and key strokes to be combined by the vnc server? Or do you want one participant to control the server at a time? The combination of client inputs is already working natively - you can use VNC in kollaborative mode, where all clients are allowed to give input - quite messy sometimes :-) Also, you can configure it the way that only one (or a subset of) client(s) has control - the other would connect read-only then. Our exact problem is that you specify that behaviour on startup - we would like to move the input fokus around on runtime... I ask because I am a graduate student doing research in this area. As a part of the research, I have been modifying the Windows vnc 3.3.7 server and client to support multiple clients, but only with one client in control at a time. The other clients can observe, ask for control, and get it, in a manner similar to Microsoft NetMeeting. That sounds about what we want! :-) As said, I do not know about windows - is your work portable to the Unix-version of VNC? Cheers, thanks for your reply! Andre Stefan. andrew. Andrew Chan M.Sc.

No, vnc does not support FTP... several flavors of vnc (mainly windows version) support an internal file transfer. I don't know if realvnc supports the file transfer though...

RE : Starting VNCViewer by right clicking on Machine in Network Neighborhood
Yes, I find it very useful! I'd like to know where you'd found documentation about the use/syntax in this particular registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\ The .cmd file is used to trim off the first \\ from %D.

My brother came up with this. I've only tested this on Windows 2000 and it works great. Sometimes the simple stuff is really elegant... Here is a registry key to import: -cut here vnc.reg Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\VNC] [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\VNC\command] @=c:\\startvnc.cmd \%D\ --- cut here Here is the command file to launch VNCVIEWER - name it startvnc.cmd or change the name in the registry key. cut here--- startvnc.cmd set addr=%1 start C:\Progra~1\RealVNC\vncviewer.exe %addr:~3,-1%:5900 exit cut heree--- Just import the registry key, copy the above commands to a file named c:\startvnc.cmd. That's all there is to it. This depends on the NETBIOS name of the computer being the same as the DNS name, which is the default. Hope someone finds this useful.

VNC 4.0 beta on Trusted Solaris 8
Hi, I'm trying to run vnc on a trusted solaris box, specifically using x0vncserver. Here is my output. $ ./x0vncserver --passwordfile=../.vnc/passwd Wed Nov 12 15:37:50 2003 main:XTest extension not present main:unable to inject events or display while server is grabbed Using shared memory XImage main:Listening on port 5998 Now, when I try to connect from a vncclient (a winxp client in this case) it prompts for the password, then I get a blank white screen.

Re: VNC 4.0 beta on Trusted Solaris 8
Sounds like the whole point of Trusted Solaris is to stop things like VNC. I doubt it will be possible to run an x0vncserver on this box unless you replace its X server with an ordinary Solaris X server (thereby reducing the security of the system). They've taken out the XTest extension from the X server, which means there's no way for x0vncserver to inject mouse or keyboard events. I wouldn't be surprised if they've also stopped the XGetImage call from working, so there's no way to get the screen image.

RE: Embed into IE

RE: Embed into IE
The RealVNC server has a java viewer built right into it and runs on port 5800. If you are using it on *nix on different ports, it's port 580X where X is the display number. The java server is turned on and off with a registry key HTTPConnect being set to a dword of 1. More information on this is in the VNC documentation. One of the many features of VNCScan is that it will export your list of detected computers to a web page that makes use of this java server on each computer.

Re: VNC to Host Behind NAT
Make sure no firewall is running on either machine and test it again. If you can do a reverse connection, it seems that the host machine is blocking the incoming connection. VNC is not likely to be the issue. My experience is it is most always something else. Do you connect properly with NAT disabled or is VNC still not working at that time? Todd Evans said: Hello, I have seen some posts regarding this but none of the advice has solved my trouble. Here's what I've got. A Netopia Caymen 5300 router on a DSL connection. The router is set for NAT. I have configured the router to allow traffic on ports 5900 and 5800 to be forwarded to my host machine. The client is not able to find the host from outside the LAN unless I completely disable NAT. Netopia tech support says that I have configured the pinholes through NAT properly and the issue must be with WinVNC. Both the Host and Client computers are running Windows XP Professional. The client computer only has VNC viewer installed. If I set the remote machine to Viewer (listen) I can connect to it from behind the router but so far no luck going in the other direction. Help!
