How to jump out of campus network screen download learning materials?

After the beginning of a certain action, the Campus network screen, but mistakenly put useful information also "ban" off, how can "jump" out of the campus, download their own much-needed learning materials? Here's a jailbreak tutorial for everyone.

Believe that everyone in the school dormitory online to facilitate the general access to the campus network, right? As we all know, the campus network for security and other aspects of consideration, shielding some websites, even some learning information sharing site is also blocked. Shielding the right resources to download, this for the free spirit of the contemporary college students of course unbearable, then how can we get the learning materials we need?

Technical thoughts and hints

Opera Browser believes that everyone is not unfamiliar, but its unique opera turbo technology believe that we still do not know (Figure 1). Opera's unique turbo technology can compress the user to specify the page to be browsed, compressed and then sent to the target computer, by the target computer's opera client to resolve the restoration. The use of data traffic to the Internet users, not only save a lot of internet traffic, because the Web page data after two compression, and the speed of the Internet has greatly improved. We carefully analyze, the compressed Web page data by who is responsible for transmission to you? Yes, it's opera's server. So we do not have to directly access the target site to obtain the content of the site, opera server played a "proxy" role, thus bypassing the campus network restrictions on the site. One might ask, why not use an HTTP proxy server or a VPN proxy server? Very simple, HTTP server not only unstable, and speed is not generally slow, the VPN proxy server really good, but most of the charge. With the use of opera browser "Jailbreak" method because of the use of local networks, speed and stability is naturally other escape methods have no comparison. But there is one problem that needs our attention, Opera desktop version of opera Turbo technology seems to have been invalidated, not normal use. But the mobile phone platform opera can be used normally. So we change a way of thinking, let the computer simulate the Java environment, run opera MINI Java version to achieve "jailbreak."

Specific implementation methods

First need to install Java environment, open http://www.java.com/zh_CN/, click "Free java download" Download installation software.

Then download the opera MINI Java version and PC-side mobile Java simulator Kemulator V0.98 (Chinese version). After the download completes decompression, runs KEmulator.exe into the Java simulator. Click on "file → load jar", select just download the Opera Mini jar file, then, the program automatically opened the Opera Mini. Because the program defaults to the reason, the window is very small, browsing is not very convenient, so we have to set it. Click view → options in turn. In the Customize column of custom properties, modify screen width and screen height to 768 and 560, confirm the return to the program interface, click file → restart, and then expand to the window size you set (Figure 2).

After resizing the window, you can start to use, in the Java emulator interface, mouse and keyboard some specific keys to simulate the mobile phone keyboard, in the "view → options → key" column can adjust their settings. Mouse click on the Opera interface "input URL", you can use the virtual out of the keyboard input.

Since then, the campus network Perfect "jailbreak" success. However, there are some drawbacks. Web sites that are limited by operators, such as YouTube, cannot escape the "jailbreak" success. About the use of analog opera download files in the location is extracted from the PC side of the mobile phone Java simulator kemulator V0.98 root directory under the Fileroot.
