I have Kubuntu Edgy installed and was playing around on the internet when a message popped up that said "The remote user has closed the connection" I have KRFB enabled to allow uninvited connections but I have a password protecting that and I am not announcing on the network. I was looking to be able to connect to the machine remotley and thought that this would be a good idea. Is there someway of getting on my machine or cracking the password that I have set? This is a little concerning to me if someone was on my machine watching what I was doing and has full control over the machine.

Thanks in advance.
