RE: VNC viewer and cd/thumb/flash/usb drive
Mike, HKEY_CURRENT_USER is writable by the current user, by definition - it's set to refer to the user's registry hive when they log on. In the case of the Guest user, this is a temporary copy of the default user registry hive, and so any data saved to it won't persist. Installing applications requires write access to parts of HKEY_LOCAL_MACHINE, as well as to parts of the filesystem, which is why non-Admins can't normally install apps to systems.

RE: Connection: Blacklisted: xxx.xxx.xxx.xxx
David, Something running on the server whose IP address is listed is connecting to all your VNC servers every so often, but not authenticating itself. It therefore becomes blacklisted after a while.

I'm thinking that the answer is yes because it won't be able to create the registry entries. It's written to this area: HKEY_CURRENT_USER\Software\RealVNC\VNCViewer4 According to Microsoft... http://www.microsoft.com/technet/prodtechnol/windows2000serv/r eskit/regentry/51211.mspx?mfr=true "A new HKEY_CURRENT_USER subtree is created each time a user logs on."

Also according to Microsoft: "The HKEY_CURRENT_USER subtree does not contain any data. It just stores a pointer to the content of..." So if something is stored in HKEY_CURRENT_USER it is also being written somewhere else. The reason I am interested in this is that some friends in another department have a very heavy-handed IT staff that won't allow them to install any programs. I'm wondering if there is no way around this restriction.

Re: realvnc server behind proxy
Brendan: Heya. Getting VNC to work across a proxy is a bit tricky: usually, it is required that you first establish a "proxy-aware tunnel" of some sort. That is, you would first run some software on the VNC Viewer PC that established a connection with a server on the "other" side of your proxy -- this can be arbitrarily simple or complex, depending on the sophisitcation of your proxy server. Once that connection is establish, though, you can then "tunnel" a VNC session via that connection. Utilities like SSH, ProxyTunnel, or EchoVNC are the ones I have in mind. I hope that helps! -Scott hello can realvnc server use an outgoing connection to connect to a sort of repeater instead of an incoming connection as normal. i want to setup a realvnc server behind a proxy server that blocks incoming connections. please reply soon thanks very much brendan ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
Removing VnC configuration settings after uninstalling..

Re: realvnc server behind proxy
Brendan: Heya. Regarding SSH and proxytunnel, do you have access to a Linux/*nix server anywhere? Makes life easier for this part. Regarding EchoVNC, two things to note: first, most web proxy's will not allow connections to "non-standard" ports, like what VNC and echoServer use by default. The proxy's will -- usually -- only allow a connection to TCP 21, 80 or 443, but nothing else. We run a demo echoServer on 443 to help with that: "demo.echovnc.com:443" (password "demo2007"). Any chance you can connect with that hostname? Secondly, EchoVNC tries to use IE's proxy settings, but you may need to provide proxy host information in the "Advanced..." button, in the echoServer tab. cheers, Scott On Mon, 22 Oct 2007, brendan kehoe wrote: Scott can you tell me how do you put the vnc session through an ssh tunnel or other proxytunnel tunnel also echovnc would not connect to the echo server for me ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list

Re: realvnc server behind proxy
Brendan: Yep, Ubuntu will do. Similar to what you did for EchoVNC... setup a proxytunnel server to listen to TCP 443 on your Ubuntu PC, and see if you can login from your Viewer PC. A pretty good description of it is here: http://proxytunnel.sourceforge.net/usage.php Glad to hear that EchoVNC connected for you; every now and then, Microsoft patches their ISA server in a different way, and I have to go back and revist the NTLM authentication again. :) cheers, Scott On Mon, 22 Oct 2007, brendan kehoe wrote: well i have a computer with ubuntu desktop would this do for ssh and proxytunnel or would i have to install ubuntu server or similar things are looking good with echovnc i have to just get another computer into my group to test it thanks very much scott brendan ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list

Re: realvnc server behind proxy
Brendan: I think I understand your setup to be: Windows-PC <-proxy-> Internet <-> Ubuntu-PC When I said "Viewer", I presumed you wanted to start a VNC Viewer on the Windows-PC, and connect to a VNC Server that could connect directly with the Ubuntu-PC (either via the Internet, or via a LAN). To do that with proxytunnel, you'd setup a proxytunnel server on the Ubuntu-PC, listening to TCP 443, and connect to it with a proxytunnel client running on the Windows-PC (or, ideally, on a Linux PC on the same LAN as the Windows-PC -- proxytunnel requires cygwin to run on Windows, which can be a bit of a hassle, but not too bad). To do it with EchoVNC, of course, it would look like: VNC Viewer <-proxy-> Internet <-> echoServer <-> VNC Server or VNC Server <-proxy-> Internet <-> echoServer <-> VNC Viewer Which, if it works, is easier. cheers, Scott On Mon, 22 Oct 2007, brendan kehoe wrote: the ubuntu computer has a direct internet connection the computer behind the proxy has windows on it when you say my viewer pc do you mean the ubuntu one outside the proxy? also, is making a tunnel through the proxy, from the windows computer inside the proxy, to a port on the ubuntu computer outside the proxy, setting up a proxytunnel server to listen to tcp 443 on the ubuntu computer? thanks very much brendan ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
