How To Set a Proxy in Ultrasurf – Alphr
Labeled as an internet censorship circumvention solution, Ultrasurf is a freeware app released way back in 2002. Its main goal was to allow Chinese users to bypass internet geo restrictions known as the “Great Firewall of China” the years, the software underwent many modifications. And, although the program does an exceptional job, it cannot always reach its maximum potential. This isn’t because of any coding issues but rather due to a lack of funding and an insufficient number of servers. The demand for firewall circumvention software keeps going It WorksFrom a user standpoint, Ultrasurf is one of the simplest programs you’ll ever use. Once you download the client, you simply have to double click the executable file. The program doesn’t install anything on your computer. Ultrasurf was originally designed for Internet Explorer but has since received updates. It is now also compatible with Firefox and Chrome, but there are still limitations to what it can most obvious limitation is its incompatibility with Linux-based operating systems. Unless you’re a Windows user, Ultrasurf won’t be able to help you browse the “forbidden” websites you want to to Use UltrasurfAfter you’ve downloaded Ultrasurf, extract the executable file into a folder of your choosing. Double click the file to launch the first thing you will notice is the simple yet elegant Ultrasurf window interface. Three servers will appear. If you want to pick a preferred server, you can. However, the first time you run it, Ultrasurf will pick the server with the fastest connection for a connection has been established, Ultrasurf will open Internet Explorer as the default browser. Usually, this is everything you need to do in order to bypass anging Browser Settings to use Ultrasurf Port – FirefoxOpen your Firefox browserGo to “Tools”Click on “Options”Select “Network”Click “Advanced”Click “Settings”Check the “Manual proxy configuration” boxType “127. 0. 1” or another proxy you want to useFor the port type “9666”Changing Browser Settings to use Ultrasurf Port – ChromeFirst, you need to be sure that your default browser is set to Google Chrome. Once you’ve done that, you can proceed with the following steps:Open ChromeGo to “Settings”Select “Advanced Settings”Locate “Network”Click “Change proxy settings”Go to “Connections”Open “LAN settings”Uncheck “Automatically detect settings”Check “Use a proxy server for your LAN”Type in the Ultrasurf proxy server address and portClick “Ok” then “Apply”Notes on Installing UltrasurfUltrasurf still works best with Internet Explorer. There are plenty of online user reports mentioning bugs when trying to use Ultrasurf with another browser, especially Chrome. However, you probably won’t have to wait too long for hotfixes and updates even if you use Ultrasurf with a different may also be interested in knowing that Ultrasurf has launched its own VPN extension for Chrome users. You can easily find it in the Chrome web store and add it to your extensions list. It has a great rating and does basically the same thing as the parent ever, people will be able to see that you have Ultrasurf installed on your browser. It defeats the purpose of running incognito, if that’s what you were going Can’t It Be Used for? Although it is created to combat censorship, Ultrasurf comes with some content filtering. It blocks access to a wide pool of pornographic websites. This is quite an uncommon feature in most firewall bypassing programs but it is a welcomed feature for many say that it keeps the app honest and true to its goals – to bypass national censorship laws, without facilitating access to illegal or offensive internet content. On the other hand, some speculate that the only reason this feature is in place is that Ultrasurf doesn’t have enough bandwidth to accommodate all the people who would use it to view pornography. Both theories have Popular Uses for UltrasurfThe beauty of Ultrasurf is that it runs undetected. It’s great that you can bypass firewalls and geo-restrictions, but it’s also amazing that the program itself can’t be blocked. This means that the software is very popular on college campuses and in office workplaces. Remember that you don’t have to install the program, so you don’t need administrative privileges on a computer in order to run it.

UltraSurf is a freeware Internet censorship circumvention product created by UltraReach Internet Corporation. The software bypasses Internet censorship and firewalls using an HTTP proxy server, and employs encryption protocols for privacy.
The software was developed by two different groups of Falun Gong practitioners at the same time, one starting in the US in 2002 by expatriate Chinese. [1] The software was designed as a means of allowing internet users to bypass the Great Firewall of China. It currently[when? ] boasts as many as 11 million users worldwide. The tool has been described as “one of the most important free-speech tools on the Internet” by Wired, and as the “best performing” circumvention tool by Harvard University in a 2007 study;[4] a 2011 study by Freedom House ranked it fourth. [5] Critics in the open-source community, George Turner Says, have expressed concern about the software’s closed-source nature and alleged security through obscurity design; UltraReach says their security considerations mean they prefer third party expert review to open source review. [6]
Overview[edit]
In 2001, UltraReach was founded by Chinese dissidents in Silicon Valley. Shortly after, UltraSurf was created to allow internet users in China to evade government censorship and monitoring. [1] As of 2011 UltraSurf reported over eleven million users worldwide. [7] During the Arab Spring, UltraReach recorded a 700 percent spike in traffic from Tunisia. [7] Similar traffic spikes occur frequently during times of unrest in other regions, such as Tibet and Burma during the Saffron Revolution. [1] Wired magazine in 2010 called UltraSurf “one of the most important free-speech tools on the Internet” for enabling citizens to access and share information from oppressed countries during times of humanitarian or human rights crises. [1]
UltraSurf is funded, in part, through contracts with the U. S. government’s Broadcasting Board of Governors, which administers Voice of America and Radio Free Asia. [7] As of 2012, UltraReach has had difficulty serving its growing user base due to insufficient funding. [8]
Operation[edit]
Client software[edit]
UltraSurf is free to download and requires no installation. UltraSurf does not install any files on the user’s computer and leaves no registry edits after it exits. [4] In other words, it leaves no trace of its use. To fully remove the software from the computer, a user needs only to delete the exe file named It is only available on a Windows platform, runs through Internet Explorer by default, and has an optional plug-in for Firefox and Chrome. [9]
The UltraReach website notes that “Some anti-virus software companies misclassify UltraSurf as a malware or Trojan because UltraSurf encrypts the communications and circumvents internet censorship. “[10] Some security companies have agreed to whitelist UltraSurf. [11] According to Appelbaum, the UltraSurf client uses anti-debugging techniques and also employs executable compression. [12] The client acts as a local proxy which communicates with the UltraReach network through what appears to be an obfuscated form of TLS/SSL. [12]
UltraSurf servers[edit]
The software works by creating an encrypted HTTP tunnel between the user’s computer and a central pool of proxy servers, enabling users to bypass firewalls and censorship. [4] UltraReach hosts all of its own servers. [4] The software makes use of sophisticated, proprietary anti-blocking technology to overcome filtering and censorship online. [4] According to Wired magazine, UltraSurf changes the “IP addresses of their proxy servers up to 10, 000 times an hour. “[1] On the server-side, a 2011 analysis found that the UltraReach network employed squid and ziproxy software, as well as ISC BIND servers bootstrapping for a wider network of open recursive DNS servers, the latter not under UltraReach control. [12]
UltraSurf is designed primarily as an anti-censorship tool but also offers privacy protections in the form of industry standard encryption, with an added layer of obfuscation built in. [6] UltraReach uses an internal content filter which blocks some sites, such as those deemed pornographic or otherwise offensive. [4] According to Wired magazine: “That’s partly because their network lacks the bandwidth to accommodate so much data-heavy traffic, but also because Falun Gong frowns on erotica. “[1] Additionally, the Falun Gong criticism website, alleged to be operated by the Chinese government, is also unreachable through UltraSurf. [12]
Evaluation[edit]
This section needs to be updated. Please help update this article to reflect recent events or newly available information. (June 2020)
In a 2007 study, Harvard University’s Berkman Center for Internet & Society found UltraSurf to be the “best performing” of all tested circumvention tools during in-country tests, and recommended it for widespread use. In particular, the report found that UltraSurf effectively bypassed various forms of censorship and blocking, include IP block, DNS block, and keyword filtering. It was also the fastest tool during in-country tests, and was noted for being easy to use and install with a simple user interface. [4] The report noted, however, that UltraReach is designed primarily as a circumvention product, rather than as an anonymity tool, and suggested that users concerned about anonymity should disable browser support for active content when using UltraSurf. [4]
A 2011 report by the U. -based human rights group Freedom House ranked UltraSurf fourth overall among censorship circumvention and privacy tools, as measured by a combination of performance, usability, support and security. In particular, the tool was recommended for users interested in downloading or viewing information, who required a relatively high degree of privacy, and who favored a fast connection speed. [5]
Some technologists have expressed reservations about the UltraReach model, however. In particular, its developers have been criticized by proponents of open-source software for not allowing peer review of the tool’s design, except at the discretion of its creators. Moreover, because UltraReach operates all its own servers, their developers have access to user logs. This architecture means that users are required to trust UltraReach not to reveal user data. [1][4] UltraReach maintains that it keeps logs for a short period of time, and uses them only for the purpose of analyzing traffic for signs of interference or to monitor overall performance and efficacy; the company says it does not disclose user logs to third parties. [6][1] According to Jacob Appelbaum with the Tor Project, this essentially amounts to an example of “privacy by policy”. [12]
In an April 2012 report, Appelbaum further criticized UltraSurf for its use of internal content filtering (including blocking pornographic websites), and for its willingness to comply with subpoenas from U. law enforcement officials. [12] Appelbaum’s report also noted that UltraSurf pages employed Google Analytics, which had the potential to leak user data, and that its systems were not all up to date with the latest security patches and did not make use of forward security mechanisms. [12] Furthermore, Appelbaum claims that “The UltraSurf client uses Open and Free Software including Putty and zlib. The use of both Putty and zlib is not disclosed. This use and lack of disclosure is a violation of the licenses. “[12] In a response posted the same day, UltraReach wrote that it had already resolved these issues. They asserted that Appelbaum’s report had misrepresented or misunderstood other aspects of its software. UltraReach also argued that the differences between the software approaches to Internet censorship represented by Tor and UltraSurf were at base philosophical and simply different approaches to censorship circumvention. [6] A top-secret NSA presentation revealed as part of the 2013 global surveillance disclosures dismisses this response by UltraSurf as “all talk and no show”. [13]
Due to restrictions imposed by some organizations, McAfee VirusScan is flagging some Ultrasurf versions as a potentially unwanted program, avoiding its execution on those machines.
