I have just setup Opensuse on my home server and when I try to remote desktop in through a browser I get the message
TigerVnc Viewer: Error
no matching security types.

I have tried from a Linux computer and a windows computer both locally and remotely with the same result.

Correct me if I am wrong, but it sounds like you are mixing protocols. Tiger does VNC protocol, not RDP. You cannot use it for Remote Desktop access. VNC access may LOOK a lot like Remote Desktop, but under the covers they are very different.

To access a remote machine using Tiger VNC you need a VNCServer (Tiger will work) running on that remote machine.

It is also advised that you use versions at both ends that support TLC encryption. All the most recent ones do. If the versions are different, or use different encryption standards, you should expect problems or less secure operation.

BTW: I do not recommend using a browser, at least for early testing. Make sure your server is running a session for you to connect to, and use the TigerVNC vncviewer.exe on the client end first. Once you get that working, try the browser.

If that does not help, please come back with more detail on what you are running on the Ubuntu home server, and what you have installed on your client machine.

Sorry my terminology is not always correct. I am running vnc not rdp, from a mint linux workstation on the same network at present.

Oh very good. Then is the VNC on both ends the same version? (Both running TigerVNC, and the same version number or release?)
