Tips for using high-performance dual-effect firewall for LINUX

Article Title: tips for using high-performance dual-effect firewall for LINUX. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
　　 Working on Windows
Many users use both Linux and Windows, although many users only want to play games. There are three ways to run Linux and Windows on the same machine-dual boot, simulator and instant translation converter (interpretater ). The first method is, of course, install Windows and Linux on the same machine and select the technology at startup. This is a good method, but you can only use one operating system at a time. In many cases, you have to restart the entire system for a Windows application.
　　
This is why the simulator was created. VMWare and Win4Linux are two very powerful and popular commercial software that allows you to run Windows on Linux. Despite the fact that these software gives you almost all the excellent features of Windows, they do have some limitations. The running speed of VMWare is relatively slow compared to Windows alone. Although Windows 4linux can run at the same speed as Windows, it only supports Windows 98SE and below. In addition, there is no software that can ensure full compatibility with Windows applications, and cannot support a complete Windows feature Package (Windows feature set ).
　　
You can also try the real-time translation converter. WINE is a program with incredible features, but far from perfect. However, it does enable you to run Windows applications without restarting Windows.
　　
However, if you still have an idle machine, the most efficient way is to run different operating systems on each machine, however, two system interfaces are displayed on one platform-two full-screen desktops of the two operating systems run side by side. Now, this is multi-task!
　　
X allows you to perform this operation. Your Linux machine can send the output to another machine with ease. After Linux is installed, you do not need to install anything other than the network cable and power on the machine-you do not need a display, he shubenhe, or a keyboard. Everything you can do on Linux box can be done remotely. (It even includes openGL applications ). An old Linux machine can be a powerful accessory to your mp3 player system. Use software similar to Winamp for convenient control on PC. This is a good way to use Linux without changing your original system. It also provides a good use for an old hard disk.
　　
So what do you need? There is only one simple internal network and one idle machine. Linux has better hardware usage than Windows and lower requirements. Therefore, the old Pentium computer is fully qualified as long as there is more than 32 memory on fire. (Remember, you still need enough memory to ensure the normal operation of the GUI, even if it is remotely displayed ). If you plan to use this machine as your winning system, although it is displayed in Windows, you obviously still need a machine with better hardware configuration.
　　
Unfortunately, this process cannot be implemented in turn-transfer Windows desktops to Linux desktops. However, Windows2000 and XP still support some advanced functions in this aspect. It is implemented through a terminal software. (The controlled terminal will be renamed in XP ). Note that Windows desktops are not designed for remote control.
　　
Although some additional components, such as the terminal server or Norton's PCAnywhere, have made a lot of efforts to implement this function, however, this is actually like putting a wooden post ingot that is released into a circular hole. He does complete basic tasks, but neither speed nor implemented functions can be compared with what X provides. Most importantly, Microsoft has never developed client software for Linux. In the absence of source code, it is difficult for someone to write such software in the recent period.
　　
As a result, we use the final key component to achieve the fusion of the two operating systems-a Windows-based X server.
　　
　　 Noble neighbors
There are three mainstream Windows-based X servers, each of which provides similar functions as X11. you can find X11 in Linux, but like most Windows-based software, none of these software is free.
　　
You can find the trial versions of the two types of software in the CD provided this month (Dinosaur found this article on an English Linux Magazine website, specifically on the magazine's website, see the final link) StarNet Communications 'X-Win32 and LabF WinaXe. X-Win32 does not offer many additional features, but is relatively cheap, $125. The price of WinaXe is $100. it runs smoothly and is quite easy to use. For these reasons, we will introduce WinaXe here.
　　
After you have successfully installed the selected Linux release on an idle machine (please be sure you have installed a large number of window managers to try, at the same time, make sure that your telnet server has been activated), connect it to the network, and then complete the preparation.
　　
Install WinaXe on your Windows Server and run X settings at the same time.
　　
Are you using a mouse with a scroll wheel? Turn the scroll wheel and try again. Do you want to adjust to a higher resolution and more colors? Set to 16-24 bits, or automatically adjust to your Linux desktop settings (which you set when installing Linux ). Finally, click "activate animation" and "force background store" to help you improve your performance. Make sure that your window mode is "more ".
　　
Click OK to save your settings and run the X session to start your X server. You can see that X sessions are on your taskbar, but not on the screen. Next, go to your Linux machine and start the Display variable at the same time:
Export DISPLAY = [machine IP or hostname]
　　
Run a program, gnome Terminal, gimp, or netscape. run whatever you like. Note that the window manager is Windows? Nothing is more surprising than configuring the Linux kernel in Windows XP.
