Download VPN VPN to check grades and browse campus resources-ByYamu needs to check grades and needs to be an intranet user of the school, and the external network cannot access the website for checking grades. But VPN can be connected to the campus network to complete the task of checking points. The steps are as follows: Online Neighbors-Right-click property, open the network connection window, and find a new connection on the left. Choose to connect to my workplace network. Select to connect to a virtual private network. Although the company name can be filled in casually, we suggest filling in hfut, because this option will be used later, and it is recommended not to dial the initial connection, which is in line with the principle of low coupling. Fill in vpn.hfut.edu.cn directly as the next host name, and then complete it directly, and we have completed a new VPN connection. At this time, a dialing dialog box will pop up, and the user name and password will be filled in hfutvpn. It is suggested to choose to save the user name and password of the following users-anyone who uses this computer, and then click Connect, and the system will make VPN connection and enter the Intranet of the University of Technology. At this time, we will open IE browser again and enter the educational administration information network to query information, and this window will pop up: there is no problem with other software such as QQ. What's going on here? It turns out that IE doesn't know which websites need to take the vpn route and which ones need to take the local route. What it really knows is the bottom of the system network. So IE came to the wrong conclusion that all websites take VPN route, so they all add agents. It doesn't matter if it is an agent of the University of Technology to visit the inside of the University of Technology. If you visit the campus, you must collect money. You must apply for a user, pay a fee, and use it to log in to the proxy server to access the external network. Then, we only need to specify some resource networks of the University of Technology and set up agents in IE. It seems that IE can't provide the setting of "a website proxy and other websites route normally". Only the setting of "proxy for all websites, normal routing for individual websites" is provided. Do I need to change my browser? Actually, it's not necessary IE is not provided in the settings, but we can solve it through proxy scripts. We write the following contents into c:\proxy.pac (in fact, the file name and storage path are arbitrary, but the extension must be pac), that is, we use javascript scripts to judge whether we should use a proxy server. The function FindProxyForURL(url, host) {if(isInNet(host, "2 10.45.240.0", "255.255.0") || isinnet (host, "210. Otherwise, return to "Direct"; } Then go back to the place where the proxy was set just now, cancel the original proxy, check the automatic configuration script, and fill in the address file: //c:/proxy.pac (pay attention to the diagonal direction when filling in) to complete the proxy setting. At this time, when we visit external websites such as Baidu, we won't go through an agent, but we can automatically act as an agent when we visit resources such as libraries, which is really convenient. But we can't watch movies at this time, because WebPlayer2007, a movie player used by Polytechnic University, doesn't automatically use the browser proxy, so we need to manually set the proxy of the player when playing the video (only once). We can right-click the player and select the network settings: just fill in the agent 2 10.45.240.8 of Polytechnic University and the port number 8080. But it is not recommended for students whose network is far from school. If the machine is restarted or the VPN is disconnected, how can I reconnect? Is it necessary to go through the above troublesome settings? Actually, you don't have to. Many of the above steps are only set once. In the future, the system will remember that when VPN is not used, it will not interfere with the normal operation of the system and will not slow down the network speed. The next time we connect to VPN, we only need to know the VPN gateway address again with ipconfig, and then use the route add command to increase the route mapping. At this point, we can find that, in fact, we only need to map one, that is, the IP of the agent, because we basically go from the agent when accessing the intranet of the University of Technology. For example, if we use ipconfig to obtain the current new VPN local IP as 222. 195. 15.49, then we can add 210.45.240.8 222.195./kloc-as we did last time. If you think it is too much trouble to find IP every time, you can also find it in batches. We will save the following files as connvpn.bat @ echooffrouteprint 222.6438+095.15.0 > c: \ conn VPN . txt for/F " tokens = 1 * " % I in(' findstr " 222. 195. 15.0 " conn VPN . txt ')do(for/F " tokens = 1 * "%ii in (") If you don't even bother to dial vpn, you just need to add another line under @echo off in the first line, and add the dialing instruction rasdial hfut hfutvpn hfutvpn, where hfut refers to the name of the company connected to your VPN when you establish a connection on it. Then, you can put this batch on the desktop, and then when you want to connect, just double-click the connection lazily. . . Here, if you use this rasdial command, and you are an ADSL dial-up user, and you have previously selected "Automatically dial this initial connection", that is, if you associate a VPN connection with a dial-up connection, when you disconnect the VPN connection, your broadband connection will also be disconnected. Of course, we didn't choose that just now, so there won't be this problem, which shows the importance of a correct configuration to the smooth completion of the follow-up work. Finally, I would like to remind you that "including sites that do not use proxy servers" should be canceled in Internet Options-Security Tab-Local Intranet-Sites, because if it is selected by default, when you connect to VPN, your access to the external network will be regarded as a local site, and the security level will be set to "medium-low" instead of "medium", which will have a certain impact on IE security, so it is recommended to remove it. The following are some commonly used sites: home page of Polytechnic University Library http://2 10.45.242.3/ Video on Demand of Polytechnic University http://FTP://210.45.240.70//Network Media of Polytechnic University/Library Lending System http://. . . If you need other resources, go to the home page of the University of Technology and the home page of the library to find them yourself. . .
