Open the RealVNC program. You will see a text area where you can enter the server hostname (IP address). Enter your IP address with port For example. Login to remote Ubuntu server using ssh command. In this guide, you'll set up a VNC server with TightVNC on an Ubuntu server and connect to it securely through an SSH tunnel. CITRIX CHICAGO
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 options to be specified on the command-line. The argument value for the -auth option may be found previously with x11vnc -findauth. 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. To set krfb to request access each time, tick Confirm uninvited connections before accepting To set a password, type a hard-to-guess password into the Password input box.
To put krfb in view-only mode, untick Allow uninvited connections to control the desktop. There's no built-in way to only allow local connections, although see below for a solution. Once mode Krfb doesn't have a built-in way to accept the next connection then stop listening for connection attempts.
However, the following Python script will listen for a single connection then exit krfb:! Make sure that the initial ' ' character is the very first character in the file, save the file as krfb. Although this simple program won't open a window of any kind, it will quietly wait for the next VNC client to connect to your computer, then pass the connection through to krfb.
If the specified string exceeds eight characters in length, VNC uses the first eight characters of the string as the password. If the command output includes the information that is provided in the red box as shown in the following figure, VNC is started.
