The website address is: http://www.vnn.cn/ There is an article about this software: one. The appearance of Dynamic Domain Diy VNN brings the gospel to those who want to build a personal website with their own computer, former Internet users want to build a personal website with their own computer, usually only apply for a dynamic domain name to support the intranet. However, these dynamic domain names are charged, mostly 200 yuan - 300 yuan / year. After the VNN user of the intranet establishes its own website, you can use the VNN's account as a dynamic domain name. But it is very inconvenient. If you want to use this dynamic domain name to visit your website, you must install and log in to VNN. It is obvious that there are not a few people to install a software and toss for the next half. After my exploration, I found a way to use VNN to build a dynamic domain name service, DIY's dynamic domain name can reach similar effects of the internal network dynamic domain names. As long as you have a public IP (finally static public network IP) and the spirit of serving the people, you can provide dynamic domain name services for our internal network users. My principle of this dynamic domain name is: Find a computer that has a public IP-loaded VNN acts as a server (hereinafter referred to as the server), so that VNN's internal network users can access the server through VNN. However, because the server has a public network IP, it can also be accessed by visiting accessors installed on the Internet. What we have to do is to make the server act as a bridge effect, communication visitor and intranet users. Below I will say how DIY this DIY is the dynamic domain name. We only need to install VNN on the server, apply for an account, and log in to VNN, and use a series of settings, use the VNN user of the dynamic domain name (hereinafter referred to as the client to the client) without any setting, just put his vnn account , The website name and the second-level domain name report you need are gave you. Phase I Project: Establish a mapping relationship We use the port mapping device (PortMap 1.6) to create port mapping relationships. First, download and run Portmap on the server, click "Add" on the toolbar of the main window to open the settings window (Figure 1), which can be arbitrarily entered in the Name (such as Web1). Enter an unbeatable port (such as 1001) in the Input Port, and the input port of each mapping group cannot be repeated. Fill in the client's VNN account (such as web1.user.vnn.cn), "Output Port" in "Output Port", in "Output Port," if the dynamic domain name is used for FTP, then input 21), and When the "program runtime" hook in the upper right corner is selected, you can automatically start the port map when running the program, and then click "OK", which is added to the mapping group. The respective mappings and current status are listed in the main window (Figure 2). After completing this project, visitors on the Internet can use HTTP: // server IP: mapped port numbers (such as: http: //218.193.12.115: 1001) to directly access the mapped VNN users. Is this a bit like a dynamic domain name? Next we have to make some improvements to make them more professional. Phase II Project: Establish an address steering, improve the dynamic domain name First, install IIS (Window 2000 / XP) or PWS (Windows 98) on the server computer, allowing it to have a web server.
Then create an HTM file on the server, the contents are as follows:
Name of the client website </ title> </ head> <frameset cols = "*"> <frame src = "http : //218.193.12.115: 1001 "> </ frameset> </ html> where the number of client website needs to be displayed in line 3 <title> </ title> will be displayed on page 6" http: // "The port number of the" server IP: map "(here is 218.193.12.115:1001), so this page has a address steering function, which will be automatically transferred to the client website when access. This HTM file is then saved in the server's Web site directory (default to c: / inetpub / wwwroot /), assumes that the file is named Web1.htm, so that the accessor on the Internet uses http: // server IP /web1.htm can access the client's website. Next, we create a directory in the directory of the Web site. The directory name is the second-level domain name required for the client. It is assumed to be Web1, and moves the just's web1.htm turn file to this directory and renamed it is defaut.htm. (Ie the default home page), such a visitors on the Internet can use the http: // server IP / Web1 / Access client website, but also apply for an international domain name for the server, so that every client website will There is a secondary domain name, which is nothing distinguished with those professional dynamic domain names. Phase IIP Project: Further improvement (optional) We can do not have to apply for international domain names, and let client users apply for a free steering domain name (such as 126.com, yeah.net, etc.), fill in the above-mentioned address "HTTP: // Server IP / Web1 /" or "HTTP: // Server IP: Map", which can also access the client's website with the steering domain name. If the server only has a dynamic public network IP without static, it can also be, as long as the server applies for a free public network dynamic domain name, the "server IP" in the above settings is changed to the server's dynamic domain name. Yes, the client's website is a three-level domain name, which is not so professional. We can also add port maps and VNNs to the RUN items of the startup group or the registry, and set the VNN account to automatically log in so that the service will be automatically started. When accessing the client site with this dynamic domain name, you should transfer the data through the server, which is higher to the server's network bandwidth requirements when the access is large, we can limit the connection of each mapping group as needed to set the port mapping. The purpose of reaching the speed limit is: Fill in "Basic Settings" in the "Increase / Modify Port Mappings" page, "the maximum number of simultaneous connections" and "when an IP connection" (as shown in Figure 3) ). After the above projects are completed and tested, our dynamic domain name service can be officially opened. two. File sharing is no longer difficult If you need to mutually pass files in several computers in the LAN, the most convenient method is naturally a shared folder with an online neighbor. Since the VNN users are connected to a virtual local area network, many people naturally think that the VNN users in the virtual LAN cannot be used to share the document, and the end of the world is more than the effect.</p>
<p>However, if you open the online neighbor view, it is difficult to find the other party's computer. If you want to apply the shared document, you need to use the following method: The two sides who want to pass the file will log in to VNN, add each other, so that in the address table of VNN You can see the current virtual IP address of your friends (Figure 4). Then click "Start" → "Search", open the search window, click on "Computer or People" → "Network", enter this virtual IP address in "Computer Name", then click "Search", Wait a moment, you can find your computer's computer (Figure 5), double-click to view the shared document on the computer, and then you can easily transfer files. three. The intranet remote control is another method "computer application" This year, "My Hand through the LAN" this year's "My Hand of the LAN" in the Raiders of the Raiders mentioned in conjunction with Softether's remote control of the intranet computer, Since the function of VNN is similar to Softether, is it possible to achieve remote control of the intranet computer? The theory and practice have proven this is feasible. I will find the way you implement: First, the main control terminals are logged in to VNN, and they can add each other to get the virtual IP address. Next, remote control can be achieved by several methods described in "Internal Network Remote Control Raiders". Since the operation steps are substantially the same, just talk about the setting steps of the differences, if the reader does not understand Location, you can view this year's No. 9 and 10th article. If you use a remote desktop connection of Windows XP, enter the controlled virtual IP address (such as 10.1401.11.101) or the controlled VNN account (such as host.user.vnn.cn). After the connection is successful, it can begin remote control. If you use a remote assistance, use the Notepad to open the remote assistance file under the save, change the intranet IP to the controlled virtual IP address or the controlled VNN account (such as 10.1401.101.101:3389 or Host. User.vnn.cn:3389) If you use WinVNC to remotely control, then enter the controlled virtual IP address or the controlled VNN account, then click "OK" on the "VNC Server" column of the WinVNC Viewer. Combined with VNN Remote Control You don't have to build a virtual HUB yourself, more convenient than a combined Softether implementation, and the control speed is faster. four. Netmeeting is a powerful online conference software that comes with Windows, using it to chat, open online conferences, send files, remote control, etc. (hereby, I have been found in the program group in Windows XP. To Netmeeting's shortcut, many people think it is removed, in fact it hides in the Program files / netmeeting directory of the system disk). But Netmeeting's cross-gate network is very poor, and the internal network users can enjoy it. However, we can help Netmeeting disordered access from the bridge weaken from the VNN. Here is how to combine VNN, as for how to use NetMeeting, readers who don't understand can take a look at the help documentation itself, there is not much to say.</p>
<p>First, users who want to communicate through NetMeeting first log in to VNN, and join each other as a friend. Start NetMeeting, click "Call" → "New Call", start a window (Figure 6), enter the virtual IP address or account to call the caller, then click "Call" to connect, it will be Voice video chat, remote control, etc. are communicated. Fives. Playing games in the virtual LAN can be connected to a virtual local area network, then can we use it for LAN games? In this way, it is not necessary to bother to find an opponent in the local area network. Unfortunately, the current version of VNN does not support IPX protocols, like StarCraft, Warcraft's games that use IPX protocols are not used, and can only be used for this type of Game using IP protocol. Let's talk about how to use the VNN in CS. First, friends who want to play games will land VNN, and add each other. A person first built a CS host, to enter the game friends, use his virtual IP address to join the game, join the method is: After starting the CS, click "Enter the game" → "Online Talk" → "Add to Server", In the dialog box, enter the virtual IP address of the person to establish the host, and then click "OK" to enter the game. In this way, the game does not meet the effect of "Haofang Battle Platform", because the transmission of VNN is still unstable, and the delay in the game can be relatively large, but these shortcomings will believe in subsequent versions will be obtained. Solved, and, it is said that the new version of the IPX protocol will soon be released, and it can also come to the game battle platform DIY. six. The intranet BT speed has been very complained in the internal network of BT, but there is no way to download the download speed that is not as good as the public network, but no way, who is our internal network user. However, the emergence of this software of VNN has brought us hope. VNN's users constitute a virtual local area network, which can be accessed, so can BT reach a similar public network? After my attempt, I found that the VNN did have a certain help for the BT users of the intranet. After logging in to VNN, use some new version of BT software, such as the BitComet 0.52 version can be seen. First, in the BitComet's log, you can see the words "Found Vnn Adapter <10.140.xx>", indicating that the VNN works. Sometimes it will find Peer from the VNN user during download, those IPs 10.140.x. .x is a VNN user, but also "remote" (as shown in Figure 7). But now the VNN's users don't have a lot of speed, but with the continuous improvement of VNN's users and VNN themselves, I think the VNN is very helpful for the BT users of the intranet. Postscript VNN version is updated quickly, it is best to use the latest version when using. The current version of VNN is not very stable, sometimes the delay of the packet is large, it is recommended to use the other account first, if the delay is too big, you can log out and log in one by one, so it may be better. However, with the emergence of new versions, I think these shortcomings will be improved, so that we wish VNN to grow up growing. Published on 2004-10-19 19:06 Evernory Read (2587)</p>
