Ultra Surf


What is Ultrasurf?
Ultrasurf is a freeware proxy application. It works as a free VPN without installation. It tunnels all the http(s) traffic on the port 9666 through SSL to an american server. By using it, one can bypass censorship as well as stay anonymous on the internet.
enables users inside countries with heavy Internet censorship to visit any public web sites in the world safely and freely
works together with the GIFT (a dynamic node-proxy anti-jamming system);
requires no installation or change in system setting;
UltraSurf is a green software, no installation process is needed and no change in system setting is required. It is simply an executable file on Windows platform.
UltraSurf’s Chinese name, Wujie – meaning borderless – has become a household name among Chinese Internet users. UltraSurf is one of the “three swordsmen,” thanks partly to its user friendliness and user support in Chinese.
UltraSurf is a robust anti-censorship system evolved from the lasting battle between GFW and UltraReach. Since infancy, UltraSurf has been one of the Chinese Communists’ favorite targets. The freely available software has been analyzed, mutilated and spoofed, and the supporting network infrastructure has been constantly attacked. Without doubt, these factors have accelerated UltraSurf reaching its level of sophistication and fame. The current release, UltraSurf 8.8, has implemented a complex proxy system with complete transparency and a high level of encryption on the Microsoft Internet Explorer (IE) platform.
UltraSurf enables users to browse any website freely--just the same as using the regular IE browser--while it automatically searches the fastest proxy servers in the background. It has strong support for load balancing and fault tolerance, and it even employs a decoying mechanism to thwart any tracing effort of its communication with its infrastructure.
