VNC: Remote Control Expert in Linux

There are a lot of remote control tools and software in Microsoft Windows operating systems. Among them, we are most familiar with Symantec's pc anywhere and CA controtors. These remote control tool software can control a specific computer through the network, can share the data of that computer, operate on the computer's external devices.

Since the remote control software in Windows is so good, is there a good control tool in Linux? In fact, there are also several powerful remote control tool software in the Linux operating system platform, but these software are very few and there are not many users, therefore, Linux users do not know much about them.

The biggest benefit of remote control software is that it can access a specific computer through the network. For example, if you want to work in the office and want some information on the home computer, if you use remote control technology, you do not have to run back to the home software to copy files, you only need to dial the Internet through a computer in the office or access your computer in VNP mode, enter the user name and password, and then copy the required information. Of course, the specific software setting method is very easy to implement in Windows. Using software such as pc anywhere can also easily set the host and client computer.

On the Linux platform, some advanced users also know that the X application software under XFree86 is used to remotely control the computer. However, broadband technical support is required to remotely access the computer in this way, otherwise, it is difficult to implement. In addition, this method cannot be used across platforms. Linux Hosts cannot control computers on non-Linux platforms. That is to say, Linux Hosts can only control computers on Linux platforms, windows and Mac operating systems cannot be controlled. This will cause great inconvenience to our work.

Excellent remote control expert VNC in Linux can help us achieve Linux Remote Control. VNC (Virtual Network Computing) is short for Virtual Network computers. VNC is an excellent remote control tool software developed by the famous AT&T European research laboratory. VNC is a free open source software based on UNIX and Linux operating systems. It has powerful remote control capabilities and is highly efficient and practical. Its performance can be comparable to any remote control software in Windows and MAC.

VNC consists of two parts: the client application (vncviewer) and the server application (vncserver ). The basic operating principle of VNC is similar to some remote control software in Windows. VNC server-side applications are highly adaptable in UNIX and Linux operating systems, and the graphic user interface is very friendly. It looks similar to the software interface in Windows. On any Linux platform computer that has installed the client application (vncviewer), it is very convenient to connect to the computer that has installed the server application (vncserver. In addition, the server (vncserver) also has a built-in Java Web interface, so that the user's operations on other computers can be displayed through Netscape, this operation process and display method are more intuitive and convenient.

How do I obtain and install VNC?

1. Install the vnc rpm package

1. install linux

1.1 If the installation on the GUI is in KDE or GNOME, click the rpm package and the system will automatically start the installation. You will also be prompted to set the password and port.

1.2 installation under the command line.

Next, let's talk about the installation under the command line, which is actually very simple, just a command.

Cd/mnt/f/vnc/
Rpm-ivh vnc-3.3.6-2.i386.rpm

2. Set the vnc server access password

Vncpasswd

3. Start vnc server
Vncserver
Note the information displayed after running, and write down the port number, generally starting from 1, because 0 is occupied by x server. now you can provide the vnc service. vnc client usage will be introduced.

4. The management environment set by the vnc server on linux is twm.

Change it to the KDE. Modify $ HOME/. vnc/xstartup file. Change starttwm to startkde and restart the vnc server.

How to manage VNC?

By default, the management graphical user interface used by VNC is twm. I think you are familiar with this twm Management window. Among the many graph management windows in Linux, twm has the lowest requirements on the system, and the resource occupation line is much smaller than other management windows, which is very useful when we start VNC during Linux runtime. The default configuration parameters in the twm Management window are stored in a hidden subdirectory in/home. in the xstartup file in vnc, if you need to reconfigure twm, you can find the xstartup file in this directory and modify it.

Although the twm Management window does not look as gorgeous as KDE and GNOME, you do not need a complex graphic user environment like KDE when running VNC for remote management, in addition, KDE occupies a relatively large amount of system resources and is not easy to manage networks. twm is enough. Another good graphic user interface is fvwm2, which also occupies a small amount of system resources and is suitable for use as a VNC graphic management environment. Readers who need fvwm2 can download it from the http://www.fvwm.org.

Testing VNC is also very simple. First, run the VNC server and then run vncviewer xxx. xxx. xxx. xxx: 1. Note: xxx. xxx. xxx. xxx is the IP address or host name of your computer. : 1 indicates to start the X Display Mode. If Java classes is installed in your Linux system, you can start NETSCAPE (if you are using a Windows operating system, you can also run Internet Explorer) to connect to vncserver, enter the following URL: http: // xxx. xxx. xxx. xxx: 5801. Similarly, xxx. xxx. xxx. xxx is the IP address or host name of your computer.

After completing the preceding steps, the vncviewer Java applet will automatically load the browser and prompt you to enter the administrator password, so that you can see and manage VNC intuitively.

If you want to remotely control a computer on a Windows or MAC platform through VNC, check whether port 5800 of these computers is idle and is not occupied by other devices, because VNC must use port 5800 to communicate with other computers.

For viewers on GUI interfaces in other operating systems, you must pay special attention to the fact that viewers must work in 16-bit color display mode. If your Windows operating system cannot have 16-bit color, adjust the display mode of your computer in time. Otherwise, viewers cannot work normally.

Now, we should like to tell you that VNC can not only remotely control the computers of other operating systems through the host of the Linux system, but also even more surprising that VNC can control handheld digital products. For example, if you use a PDA (Personal Digital Assistant) on the PalmPilot and Windows CE platform, you can also use a wireless MODEN to connect to a Linux host, in this way, you can easily communicate with the Linux host at home through a wireless PDA on the subway station. It's amazing.

In the near future, VNC will also be able to control other computers through mobile phones. In the coming wireless age, the role of VNC will be valued by people. Let's have a taste for VNC.
