[B] "VNC Introduction" [/B]
Network remote control technology refers to a computer (master) to control another computer (controlled), and when the master is on the control end, just as users sit in front of the controlled terminal, they can execute the controlled application and use the system resources of the controlled terminal.
VNC (Virtual Network Computing) is a set of software developed by the at&t lab that can control remote computers. It adopts the GPL authorization terms and anyone can obtain the software for free. The VNC software consists of VNC Server and VNC Viewer. You must first install the VNC server on the controlled computer before you can control the controlled terminal on the control terminal.
(In windows, a set of well-known remote control software called pcAnywhere, is also released by Symantec.
VNC Server and VNC Viewer support multiple operating systems, such as UNIX, Linux, Solaris, windows, and MACOs, therefore, you can install the VNC Server and VNC Viewer in different operating systems for control. If the current master computer does not have VNC Viewer installed, you can control the control end through a general web browser.
The workflow for running the entire VNC is as follows:
(1) connect the VNC client to the VNC server through a browser or VNC Viewer.
(2) The VNC server sends a dialog window to the client, requiring that you enter the connection password and access the VNC Server display device.
(3) After the client enters the online password, the VNC Server verifies that the client has access permissions.
(4) If the client passes the VNC Server verification, the client requires the VNC server to display the desktop environment.
(5) The VNC server uses X protocol to require X server to assign control of the display to the VNC server.
(6) The VNC server will be sent to the client using the VNC communication protocol in the desktop environment of X server in the future, and allow the client to control the desktop environment and input device of the VNC server.

[B] "Installation and Use of VNC" [/B]
My operating environment: redhat8.0 on the control side and Windows XP on the control side.
[B] 1. Load VNC Server and VNC Viewer. [/B]
VNC Server: http://www.linuxeden.com/download/softdetail.php? Softid = 744
VNC Viewer: http://download.pchome.net/php/dl.php? SID = 1, 2603
[B] 2. install. [/B]
Rpm-uvh vnc-3.3.6-2.i386.rpm (for source code, see the instructions in the package)
Install winvnc.exe
[B] 3. Start VNC Server on Linux [/B]
Run the vncserver command:
[Root @ linux root] # vncserver
You will require a password to access your tops.
Password: ---- to prevent anyone from remotely controlling the computer. Therefore, when
Verify: --- when you start the VNC Server once, you must set a password for remote control.
New 'X' desktop is Linux: 1 ---- remember this line will be used later.
Creating default startup script/root/. VNC/xstartup
Starting applications specified in/root/. VNC/xstartup
Log File is/root/. VNC/Linux: 1.log
(After the preceding steps, the VNC Server is started. If you want to change the VNC server password, you only need to execute the vncpasswd command .)
[B] 4. Run VNC Viewer on Microsoft Windows [/B]
Run unzip vncviewer.exe directly. The connection details dialog box is displayed.
In the connection details dialog box, enter the IP address of the VNC Server (or host name and display device number) in the "VNC Server" text box (see 3. Start this line of the VNC Server on Linux. New 'X' desktop is Linux: 1 to get this information. For example: 192.168.0.1: 1 (1 after the colon is the display device number generated by the VNC Server). After you click the "OK" button, the VNC server starts to check the entered information. If the information is incorrect, the system displays the "failed to connect to server" error message: if the information is correct, the "VNC authentication" dialog box appears.
If the password entered in the "VNC authentication" dialog box is correct, you can successfully open the Linux desktop window.
[B] 5. remote control from the browser. [/B]
Start the VNC Server and open your browser. in the address bar, enter the address or IP address of the controlled terminal, and add the port number ": 5800 + display number" to the address to control the computer.
For example: http: // 192.168.01.: 5801 (if the display number is 1, the display number set for the first time is 1, then 5800 + 1 = 5801 is used .)

[B] 6.faq[/B]
A. Why is there only one terminal window on the desktop after the connection?
Try to modify/root/. VNC/xstartup and change the last line of TWM & to gnome-session & or KDE & (it is said that KDE is not stable in the current VNC Viewer)

B. Why can't I connect after I restart the VNC server?
When you restart the VNC server, the system will specify a new display number. You must use this new number. Otherwise, the connection will fail.
(The above are just some of my problems, and there are not many VNC problems, which are not comprehensive. I hope to provide more valuable comments)C. Why can't I display letters and numbers when my VNC Viewer can be normally connected?This problem also left me around for half a day. I found the information on the Internet. The VNC server requires that the OS Input Method on the VNC Viewer side be consistent with the OS language on the VNC server side. Generally, the Linux OS we installed is in e-files. Therefore, when you connect to the VNC Viewer, disable the Chinese Input Method of the local OS and switch to English. Try it now.
