VNC (Virtual Network Computing) is a graphical desktop-sharing system that can be used to control a remote computer. It transmits mouse and keyboard events from one node to another on a network and updates the graphical screen on the other end of the network. Virtual Network Computing is platform-independent. This server makes use of the RFB (Remote Frame Buffer<\/a>) protocol.<\/p>\n\n\n\n

Virtual Network Computing depends on two modules:<\/p>\n\n\n\n

VNC server<\/p>\n\n\n\n

and<\/p>\n\n\n\n

VNC client<\/p>\n\n\n\n

This server listens to the incoming connections from the client. VNC can be used to work on the GUI of your VPS.<\/p>\n\n\n\n

<\/p>\n\n\n

Please note that Veeble servers have VNC pre-installed.<\/strong><\/h3>\n\n\n

1. First check whether vncserver is installed on the server.<\/p>\n\n\n\n

yum list vnc-server. \n<\/pre>\n\n\n\n
If not, you can install the package using yum install vnc-server.<\/p>\n\n\n\n
yum install vnc-server\n<\/pre>\n\n\n\n
2. Set up a vnc password.<\/p>\n\n\n\n
Type the ” vncpasswd ” command in the shell. This prompts you to enter the password. You can use a strong password. By default, this is saved in \/root\/.vnc\/passwd<\/p>\n\n\n\n
vncpasswd\n<\/pre>\n\n\n\n
3. Open the file \/etc\/sysconfig\/vncservers to set up in session.<\/p>\n\n\n\n
At the bottom add the following lines.<\/p>\n\n\n\n
VNCSERVERS=\"1:root\"\nVNCSERVERARGS[1]=\"-geometry 1024x768 -depth 16\"\n \n<\/pre>\n\n\n\n
Here 1 means the session number.<\/p>\n\n\n\n
4. Install kde and gnome environments.<\/p>\n\n\n\n
yum install kde*\nyum install gnome*\n<\/pre>\n\n\n\n
5. Setting up vnc startup script.<\/p>\n\n\n\n
Open the file \/root\/.vnc\/xstartup and add the following lines to get a KDE desktop.<\/p>\n\n\n\n
#!\/bin\/sh\n# Uncomment the following two lines for normal desktop:\nunset SESSION_MANAGER\nstartkde &\n<\/pre>\n\n\n\n
You can comment on the previous entries.<\/p>\n\n\n\n
6. start vnc session<\/p>\n\n\n\n
vncserver :1 \n<\/pre>\n\n\n\n
and check whether you are able to telnet to port 5901<\/p>\n\n\n\n
root@proxy:~# telnet 123.45.2.6 5901\nTrying 123.45.2.6...\nConnected to 123.45.2.6.\nEscape character is '^]'.\nRFB 003.008\n<\/pre>\n\n\n\n
If you are not able to connect, make sure that port 5901 is open.<\/p>\n\n\n\n
8. Testing vnc.<\/p>\n\n\n\n
You can download the VNC client from here<\/a><\/p>\n\n\n\n
After downloading and extracting the VNC client in your Windows machine, open vnc client. In the server field, enter the following details.<\/p>\n\n\n\n
serverip:1\n<\/pre>\n\n\n\n
This prompts you to enter the vnc password. If everything goes well, you will be able to see the KDE desktop.<\/p>\n\n\n\n
7. To kill a vnc session, use<\/p>\n\n\n\n
vncserver -kill :1\n<\/pre>\n\n\n
OR<\/span><\/h4>\n\n\n
Download the GNOME Desktop environment to your server:<\/p>\n\n\n\n
yum groupinstall \"Desktop\"\n<\/pre>\n\n\n\n
After installing the GNOME Desktop environment then start to install the TigerVNC server<\/p>\n\n\n\n
yum install tigervnc-server xorg-x11-fonts-Type1\n<\/pre>\n\n\n\n
Now your VNC is installed on your CentOS 6.<\/p>\n\n\n\n
Start the VNC server.<\/p>\n\n\n\n
vncserver\n<\/pre>\n\n\n\n
This asks you to enter the password now.<\/p>\n\n\n
VNC Client<\/span><\/h2>\n\n\n
Now time to connect to your VNC Server:<\/p>\n\n\n\n
First download the appropriate VNC client from here<\/a><\/p>\n\n\n\n
Then use it to connect to your server.<\/p>\n\n\n\n
Use the following entry as the VNC address:<\/p>\n\n\n\n
IP:1\n<\/pre>\n\n\n\n
Enjoy your VNC Server<\/p>\n\n\n\n
