You will need a VNC server if you want other people to see your desktop. Every VNC server has different strengths and weaknesses and is appropriate for different uses. Common security options The most important thing when setting up a VNC server is to only let the right people access your desktop. The safest way to do that is usually to have someone sitting at the desktop deciding who gets to use it, but that's not always practical - for example, if you want to log in to your own computer from somewhere else.

If you want to confirm each connection manually, you should look for these options: Request access each time - pop a window up asking whether to allow each connection as it comes in. As well adding a little security, this avoids problems with both of you fighting over control of the mouse. Using these two options will give you the most security.

Requesting access each time will ensure that nobody can connect without you noticing, and view-only access will mean that they can't change anything without asking you to do it for them. If you want to access your desktop when nobody is sitting at it, these options will be more useful: Only allow local connections - only let people connect if they already have access to your computer.

Set a password - require people to send a password before they can connect. These three options should give you a secure set-up, so long as they're used with port-forwarding. Only allowing local connections means that only people with user accounts on your computer can access your desktop. Starting the server in "once" mode means that people with user accounts on your computer would have to log in to your desktop between the time you start your VNC server and the time you connect from your VNC client.

Setting a password means that, if anyone did try to connect in that brief interval, they probably wouldn't be able to get in before you noticed and stopped the server. There's no way to set vino to only listen for the next connection. To set a password, tick Require the user to enter this password: , and enter a hard-to-guess password.

To put vino in view-only mode, untick Allow other users to control your desktop. To only allow local connections, open a terminal and run the command: gsettings set org. Vino network-interface lo To allow connections from anywhere, open a terminal and run the command: gsettings reset org. Vino network-interface x11vnc x11vnc is a VNC server that is not dependent on any one particular graphical environment. It can be started while your computer is still showing a login screen. It is helpful to ensure you have uninstalled any other VNC programs first so that they don't interfere with x11vnc.

To set x11vnc to only listen for the next connection, include the -once option. To set x11vnc to continually listen for connections, include the -forever option. To put x11vnc in view-only mode, include the -viewonly option. To set x11vnc to only allow local connections, include the -localhost option.

Xauth -display :0 If you find a blank screen, check the x11vnc FAQ entry on headless servers. Because it's highly integrated with KDE, running it in other environments is difficult.

Improve this answer. Maybe I'm confused, but wouldn't that just forward port from the client machine to on the client machine? No, it forwards on the client machine to on localhost -- from the point of view of the server, not the client.

So localhost would refer to the server. DepressedDaniel DepressedDaniel 1 1 bronze badge. I dont think this makes any significant improvement in security with jjlin's answer. In his answer explicitly isn't listening on anything but localhost which is what OP wants. At that point, I don't see how blocking tcp access would make it any more secure — user The -localhost option of vncserver doesn't do anything to the X server which may listen on, e.

Since the vncserver process is running on the same machine, it can connect to the X server using unix domain sockets, and this is what it does by default. Ah I see, thanks for explaining. You might want to add that to your answer, that's seems like a pretty big gotcha. Didn't know this, thanks for sharing — user Sign up or log in Sign up using Google.

Most programs treat dual monitors as being one huge display with a large horizontal resolution, including Windows; there's extra programming involved to get the behavior to appear as two different windows. For example, this is why Windows records dual monitors as one picture when you take a fullscreen screenshot. One program that can do what you want is Teamviewer. There is a Linux version available that supports CentOS.
