Vnc:linux remote control expert _unix Linux

There are so many remote control tools in Microsoft's Windows operating system that most people are familiar with is Symantec's PC ANYWHERE, CA controlit, and so on. These remote control tool software can control a particular computer through the network, can share the data of that computer, operate the external devices on the computer.

If the remote control software is so good under Windows, is there a handy control tool software in the Linux platform? In fact, there are several powerful remote control tool software in Linux operating system platform, but these software is very few, the user that uses is not many, so the average Linux user knows to them not much.

The biggest benefit of remote control software is the ability to access specific computers over the network. For example, you work in an office, if you want to have some information on your home computer, if you use remote control technology, you don't have to run back to the Home software copy file, as long as you can access your home computer by dialing through the office computer or by VNP, enter your username and password, Can be copied to the information you need. Of course, the specific software setup method is easy to implement under Windows, and using software such as PC anywhere can also easily set up host and client computers.

Some of the advanced users on the Linux platform also know that by using the X application software under XFREE86 to remotely control the computer, it is difficult to access the computer in such a way that it requires broadband technical support. Also, this way can not be used across platforms, Linux hosts do not control the non-Linux platform computers, that is, Linux hosts can only control the Linux platform computers, not control Windows and Mac operating system computers. This will bring great inconvenience to our work.

Under the excellent Linux remote control expert VNC can help us realize the desire of the remote controlling of Linux. VNC (Virtual network Computing) is the abbreviation for a fictitious network computer. VNC is an excellent remote control tool software developed by the renowned at&t European Research Laboratory. VNC is a free open source software based on UNIX and Linux operating systems that is powerful and efficient in its ability to match the performance of any remote control software in Windows and Macs.

VNC is basically made up of two parts: a client application (vncviewer) and a server-side application (vncserver). VNC's basic operating principle and some Windows remote control software is very much like. VNC's server-side applications are highly adaptable to UNIX and Linux operating systems, and the graphical user interface is very user-friendly, and looks similar to the software interface under Windows. Computers in any Linux platform with client-installed applications (vncviewer) can be easily interconnected with computers that have server-side applications (Vncserver) installed. In addition, the server-side (Vncserver) also built a Java Web interface, so that users through the server side of the operation of other computers can be displayed through Netscape, such a process and display mode is more intuitive and convenient.


How do I get and install VNC?

One. Install VNC RPM Package

1 Installing Linux

1.1 Installation under the graphics interface if you click the RPM package directly under KDE or GNOME, the system will automatically start installing. In the middle will also prompt you to set the password, the port and so on.

1.2 The installation under the command line.

Below or to say that the installation under the command line, in fact, is very simple, a command on it.

cd/mnt/f/vnc/
RPM-IVH vnc-3.3.6-2.i386.rpm

2 Set the access password for VNC server

vncpasswd

3 Start VNC Server
Vncserver
Note the information that is displayed after the run, and note the port number used, typically starting at 1, since 0 is occupied by x server. Now you can provide VNC services. The usage of VNC client will be introduced.


4 Linux on the VNC server default management environment is TWM, not good-looking, also inconvenient.

Let's change it to KDE. Modify $home/.vnc/xstartup this file. Change the STARTTWM to Startkde to reboot the VNC server.


How do I manage VNC?

By default, VNC uses the admin graphical user interface is TWM, this TWM management window I think you must be very familiar with, in the Linux many graphics management windows, TWM to the system requirements are the lowest, the resource consumption line for other management window is much smaller, This is very useful for us to start VNC when Linux is running. The default configuration parameters for 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 xstartup files to modify in this directory.

Although the TWM Management window looks less gorgeous than KDE and GNOME, you don't need KDE's complex graphical user environment to run VNC remotely, and KDE consumes relatively large system resources and is not easy to manage on the web, and twm is sufficient. There is also a better graphical user interface is FVWM2, this graphical user interface occupies a relatively small system resources, but also suitable for the VNC graphical management environment to use. Readers who need fvwm2 can download them to http://www.fvwm.org.

Testing VNC is also very simple, first run VNC server side, 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 refers to the way to start x display. If you have Java classes installed on your Linux system, you can start Netscape (of course, if you are using a Windows operating system, you can also run Internet Explorer) to connect to Vncserver. Then enter the following url:http://xxx. xxx.xxx.xxx:5801, again, xxx.xxx.xxx.xxx is your computer's IP address or host name.

After completing the steps above, the Vncviewer Java applet is automatically loaded into the browser and prompts you for an administrator password, so you can see it visually, managing VNC.

If you want to remotely control a computer on a Windows or Mac platform through VNC, please note that the 5800 ports on these computers are idle and not occupied by other devices because VNC must use 5800 ports to communicate with other computers.

Viewers with GUI interfaces on other operating systems should also pay special attention to the viewers need to work in 16-bit color display mode, if your Windows operating system can not be 16-bit color, then please adjust your computer display mode in a timely manner. Otherwise viewers will not work properly.

Well, finally, VNC can not only remotely control the computers of other operating systems through the Linux host, but it is also surprising that VNC can control handheld digital products. For example, a PDA (personal digital assistant) using the PalmPilot and Windows CE platforms can also connect to each other via wireless Moden and Linux hosts, so that you can easily communicate with your wireless PDA and your home Linux host on the subway to work. Yes, it's amazing.

In the near future, VNC can also use mobile phones to control other computers, in the upcoming wireless era, the role of VNC will be the attention of people, let's drink for VNC.
