I have noticed that after a remote desktop session I get connectivity problems until the machine is rebooted.
I get the password prompt but after entering the password I get the error message SelectObject to CompatibleDC failed: The operation completed successfully.

Thanks, Kimberly --__--__-- Message: 2 Subject: encryption & export restrictions From: Benjamin Collar <[EMAIL PROTECTED]> To: [email protected] Organization: CT SE2 Siemens Date: Fri, 03 Jun 2005 14:20:15 +0200 Greetings I'm investigating the kinds of encryption included in VNC software. This is important because of the various export restrictions on encryption software instituted by the US and many EU countries. The RFB spec and other sources acknowledge the use of DES encryption during the initial handshaking. However, the spec says: "Note that after the security handshaking phase, it is possible that further protocol data is over an encrypted or otherwise altered channel." The handshake documentation lists other security types, but does not explain what they mean: RA2, RA2ne, Tight, Ultra, TLS. These are in addition to None and VNC Authentication. The quote from the spec does not make it clear whether the noted encryption is external to VNC (like VNC over SSH) or internal. I'm guessing that "VNC Authentication" refers to DES. What are the other "security types" and what encryption, if any, do they use? Is there encryption used anywhere else in the software? If this list is inappropriate for such a question, I would appreciate it if someone could point me in the right direction Thank you for your time Ben -- Benjamin Collar Siemens AG CT SE 2 Embedded Linux 089-636-53711 --__--__-- Message: 3 Date: Fri, 3 Jun 2005 07:45:28 -0500 From: Angelo Sarto <[EMAIL PROTECTED]> Reply-To: Angelo Sarto <[EMAIL PROTECTED]> To: "Kampert, Kimberly" <[EMAIL PROTECTED]> Subject: Re: Listening VNC Viewer Cc: [email protected] A listening Viewer allows the "Server" computer to connect to you.

You, being technically savvy, set up your router to forward port 5500 to your machine and then you launch a listening viewer. Now I click on my tray icon and select Add new client and type your IP. Now you can help me! It is still the same program the difference is in which end initiates the connection. --ANgelo On 6/3/05, Kampert, Kimberly <[EMAIL PROTECTED]> wrote: > What is the difference between Listening VNC Viewer and VNC Viewer? > > Thanks, > Kimberly > _______________________________________________ > VNC-List mailing list > [email protected] > To remove yourself from the list visit: > http://www.realvnc.com/mailman/listinfo/vnc-list --__--__-- Message: 4 Date: Fri, 3 Jun 2005 07:57:45 -0500 From: Angelo Sarto <[EMAIL PROTECTED]> Reply-To: Angelo Sarto <[EMAIL PROTECTED]> To: Tomasz Chmielewski <[EMAIL PROTECTED]> Subject: Re: multi user / concurrent VNC sessions on Windows?

In certain situations it would be advantageous to allow a remote system (VNC server) to initiate a connection to the viewer. Executing the Listening viewer leaves the viewer dormant in your system tray till a incoming connection is received from a remote VNC server system. It is possible to run both the instances of viewer i.e. VNC viewer and listening viewer at the same time. One thing to remember with listening viewer is that any firewalls on the viewer side should be configured to allow incoming connections on port 5500 as this is the port used by Listening viewer.

Date: Fri, 3 Jun 2005 14:28:48 +0100 Organization: RealVNC Ltd. Angelo, Any multi-user version of VNC for Windows would necessarily be hooked into Terminal Services, since multi-user operation requires full support within the OS. AFAIK, Citrix licensed the full source code for Windows NT in order to produce a multi-user version, and the resulting code was the basis for what is now Terminal Services.

The UK signed the Wassenaar Arrangement--but I'm not sure if the UK government decided to implement any or all of it with respect to encryption software. Anyway, thanks again for the information.
