In computing, Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network.
1. Connecting to VNC server
Open your local VNC client, which will vary depending on your operating system.
On Windows, you can use:
On OS X, you can use the built-in Screen Sharing app or access this app through Safari. In Safari, you can enter
For your VNC Server address, enter
For first login vncuser password is: admin123
When connected for the first time, within minute vncuser password will be changed, which will appear on the user’s desktop file named “newvncpassword.txt.
For safety reasons, it is recommended to copy the new password and to delete “newvncpassword.txt” file.
If you logged out from VNC without copying new password you can find it by connecting to server via SSH with root and executing command:
2. Password changing
If you want to change randomly generated password to your own you need to go to:
Applications -> System Tools -> Terminal
You will be asked to enter and reenter new password. Password can not be longer than 8 symbols.
3. Adding new user
Connect to server via SSH with rootand execute commands below:
useradd name_of_new_user passwd name_of_new_user
You will be asked to enter and reenter password for you new user.
Now we need to configure “/etc/sysconfig/vncservers” file:
And add line:
Save and exit ( Ctrl + O, Ctrl + X).
Now we need to add password for connection via VNC for our new user. Login as our new user and add password:
su - name_of_new_user vncpasswd
Go back to root:
Restart VNC service:
service vncserver restart
For your new user VNC Server address is:
