Servers: Panda's remote control tool software in the Microsoft Windows operating system, which is most familiar with the PC Anywhere of Symantec, as well as CA Controlit, and more. These remote control tool software can control specific computers over the network, and can share the data data of that computer, and operate external devices on the computer. Since the remote control software under Windows is so good, do you have any control tool software in the Linux platform? In fact, there are several powerful remote control tool software in the Linux operating system platform, just these softwares, not many users, so the general Linux users do not know how much they know. The biggest benefit of remote control software is to access specific computers through the network. For example, in the office, you want some information on your computer. If you use remote control technology, you don't have to ran back to your home software copy file, just dial your network through your office or pass the VNP mode. You can access your computer, enter your username and password, you can copy the information you need. Of course, the specific software setting method is easy to implement under Windows, and software using PC Anywhere can also set up host and client computer. Some advanced users in the Linux platform also know that remotely controls the computer by X application under xfree86, but through such a way, remote access is required for broadband technical support, otherwise it is difficult to implement. Also, this method cannot be used across platforms. Linux hosts cannot control the computer of non-Linux platforms, that is, Linux's host can only control the computer of the Linux platform, and cannot control the Windows and Mac operating systems. This will give us a lot of inconvenience. Excellent Linux Remote Remote Expert VNC can help us implement the wish of Linux remote control. VNC (Virtual Network Computing is an abbreviation for virtual network computers. VNC is an excellent remote control tool software developed by the famous AT & T European Research Lab. VNC is a free open source software based on UNIX and Linux operating systems, powerful, efficient and practical, and its performance is comparable to any remote control software in Windows and Mac. VNC is basically consisting of two parts: a part is a client's application (VNCVIEWER); another part is the server-side application (VNCServer). The basic operating principle of VNC and the remote control software under Windows are very similar. VNC's server-side applications are very suitable in UNIX and Linux operating systems. The graphical user interface is very friendly, which looks similar to the software interface under Windows. Computers on any Linux platform installed on any installed application (VncViewer) can be very convenient and installed on the server-side application (VNCServer). In addition, the server-side (VNCServer) has also built a Java web interface so that the user can display the operation through the server side to the Netscape, such operational processes and display modes are more intuitive and convenient. How to get and install VNC? VNC This software can be downloaded by URL: http://www.uk.research.att.com/vnc/download.html VNC The latest version is 3.3.3. On this homepage also provides VNC binary code download 3.3.3r1_x86_ Linux_2.0.tgz interested friends can understand the working principle of VNC by analyzing its source code. This source compression package includes the full source code of the VNC client and server-side Linux version.
If you want other operating system version (Windows, Unix) VNC, you can also find on this home page. Regarding the installation of other Windows and Mac versions of the VNC software, you don't need to talk about it. Just double-click the VNC package with your mouse to successfully install, which is the same as those under Windows. Let's take a look at how the Linux version of the VNC is installed. First, you must decompress the VNC package downloaded to the hard drive. Use the ustar command. You can extract VNC into / home / vnc, you will find 4 files in VNCServer, vncpasswd, vncviewer, xvnc, then copy these 4 files to / usr / bin directory. If you want to control other computers over the server side of the VNC, the next step is to create a subdirectory / usr / local / vnc / class, create a directory, copy this VNC Java .class file to / usr / local / vnc / classe In the directory, perform the following commands: # mkdir -p / usr / local / vnc / class # cp classs / * / usr / local / vnc / classes Next, check whether Perl scripting scripting languages in your Linux system are installed. Perl's interpreter is in the / usr / bin / perl / directory. If you haven't installed a Perl scripting scripting language in your Linux, you need to modify the first row of VNCServer Script Specify a specific / usr / bin / perl / directory. Under normal circumstances, a Perl scripting scripting language is installed in the Linux system. Ok, the main VNC configuration steps are so much. If you have special needs, you can refer to the instructions in the VNC for specific settings. After the installation of the VNC, the server side of the VNC can be started by running in the terminal of Linux: # vncserver. After the VNC server runs, first it will ask you to enter the server password, you need to set up a protection password for the server at this time, which is a very important step. If the password is set successfully, then this will appear in Script: Display: 1 .. What does this information mean? It turns out that the VNC server side in the UNIX platform is actually running your own special terminal server to display the information of the client VncViewer in the running network. How to manage VNC? Because VNC has its own independent X Server, we can set it accordingly.
Here is to tell the reader, about the common problem solution (FQA), documentation, etc., etc. below, although all the information, how to set the VNC remote control management window, etc. The answer is very detailed, there is a need to learn more about the remote management of the VNC, the specific settings of the specific setup: http://www.uk.research.att.com/vnc/doc.htmlhttp:// / www.uk.research.att.com/vnc/faq.htmlhttp://www.uk.research.att.com/vnc/start.html In the by default, the management graphical user interface used by VNC is TWM, this TWM management window I think everyone must be very familiar. In a large plurality of graphics management windows in Linux, TWM is the lowest requirements. There is a lot of other management windows for other management windows, which starts VNC when running in Linux. It is very useful when it is. The default configuration parameters of the TWM management window are stored in the xstartup file in the / home in the subdirectory. If you need to configure the TWM, you can find the XStartup file in this directory for modification. Although the TWM management window seems to be as gorgeous as KDE and GNOME, you don't need the complex graphical user environment as KDE when running VNC, and the system resources occupied by KDE are relatively large, and it is not easy to communicate Manage, TWM is enough. There is also a better graphical user interface is FVWM2. The system resources occupied by this graphical user interface are also suitable as the VNC graphics management environment. Readers who need FVWM2 can be downloaded from http://www.fvwm.org. The work testing for VNC is also very simple. First run the VNC server side, then run VNCVIEWER XXX.XXX.XXX.XXX: 1, note, xxx.xxx.xxx. Xxx is your computer's IP address or host name. : 1 means to start the X display mode. If you have Java Classes in your Linux system, you can start Netscape (of course if you are using the Windows operating system, you can also run Internet Explorer) to connect to VNCServer, then enter the following URL: http: // xxx. Xxx.xxx .xxx: 5801, similar, xxx.xxx.xxx.xxx is your computer's IP address or host name. After completing the above steps, the VncViewer Java applet will automatically load the browser and prompt you to enter the administrator password so you can find VNC. If you want to remotely control a computer with a Windows or Mac platform via VNC, please note that the 5800 port of these computers is idle, not occupied by other devices, because VNC must be connected to other computers to communicate with other computers. Viewers using the GUI interface on other operating systems should also pay special attention. Viewers need to work in 16-bit color display mode. If your Windows operating system can not get up 16 color, please timely adjust your computer's display mode . Otherwise, Viewers cannot work properly. Ok, let's finally tell you that VNC can not only remotely control the computer of other operating systems through the host of the Linux system, but also the VNC can also control the hand-held digital products.
