As you've probably figured out by now, VNC connections by default use another X display, rather than using the native display, or the one you see when physically using the computer. This can be quite an annoyance if you were working on the computer before remoting into it and you want to resume with the applications you had opened on the computer itself. One of the easiest ways to remote into the native display is to use the x0vncserver instead of vncserver, which we'll discuss next. Another option that's more embracive but provides for better performance is using the vnc.so module.
One of the easiest ways to remote into the native display is to use the x0vncserver instead of vncserver. From the terminal you can type x0vncserver password=YOURPASSWORD SecurityTypes=none. This will start hosting the display 0 for remote connections, protected by the password you choose. Use a VNC viewer like discussed in the previous part, however you don't have to include a display number with the IP address.
We discussed how to use remote desktop connections between Linux and Windows. We also configured our firewalls to let the traffic flow and our router to forward the traffic onto the host computer. Plus we figured out how to secure the VNC connections that pass through the Internet. Lastly we discovered how to remote into the native X display, to see exactly what is shown on the computer rather than a virtual display.
For documentation on the Linux components, remember you can use the manual pages by running the following in Terminal:
Also, don't forget to review the FAQ and support pages on the website of the particular developer.

One of the ways around the issues of security and control that make some businesses wary of cloud computing is to build a private cloud -- one that remains within the corporate firewall and is wholly controlled internally. Private clouds also increase the agility of IT an organization's IT infrastructure and make it easier to roll out new technology projects. Download this eBook to get the facts behind the private cloud and learn how your organization can get started.
