IntroductionIn 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 serverOpen your local VNC client, which will vary depending on your operating system.
On Windows, you can use:
UltraVNCTightVNC TigerVNC On OS X, you can use the built-in Screen Sharing app or access this app through Safari. In Safari, you can enter
vnc://your_server_ip:5901
For your VNC Server address, enter
your_server_ip:5901
For first login
vncuser password is:
admin123IMPORTANT!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:
cat /home/vncuser/Desktop/newvncpassword.txt
2. Password changingIf you want to change randomly generated password to your own you need to go to:
Applications -> System Tools -> TerminalExacute command:
vncpasswd
You will be asked to enter and reenter new password. Password can not be longer then 8 symbols.
3. Adding new userConnect to server via SSH with
root and 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:
nano /etc/sysconfig/vncservers
Change line:
VNCSERVERS="1:vncuser"
into
VNCSERVERS="1:vncuser 2:name_of_new_user"
And add line:
VNCSERVERARGS[2]="-geometry 1024x768"
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:
exit
Restart VNC service:
service vncserver restart
For your new user VNC Server address is:
your_server_ip:5902
