To install the specific steps for configuring VNC under Centos5 _unix Linux

Today in the company installed a bit VNC, the evening is fine, just record it, or the next installation will have to Google ^_^

Introduction to VNC
Can not exception, simply introduced under VNC bar.
VNC, all known as virtual network Computing, is a desktop sharing system. It features similar to Remote Desktop features in Windows. VNC uses the RFB (remote framebuffer-frame buffer) protocol to remotely control another computer. It sends the keyboard, mouse action to the remote computer, and sends the remote computer's screen back to the local.

VNC technology has nothing to do with platforms, and VNC viewer can be on different operating systems with VNC server. VNC supports almost all operating systems and Java, and can even access VNC Server through Java-enabled browsers. Multiple VNC clients can connect to a VNC server at the same time.

Windows log on to VNC SERVER

1. Login from IE
Enter the following address directly from IE browser:
http://xxx.xxx.xxx.xxx:5802
Enter a password to use.

2. Login from VNC view
Install VNC view on Windows, then enter Xxx.xxx.xxx.xxx:2, connect to login, and enter a password.

Remarks: If you are prompted to connection refused (10061) when you log on from VNC view, you are logged on to the CentOS system because of a problem with the Linux firewall. Select System-->preferences-->remote Desktop, check the sharing of the two items, security two do not tick, click Close, and then again with VNC view login can.
