If you ever have been to a country where Internet is heavily
censored, you might have noticed that you cannot load some of the
websites that you use to go to. Your only option in this case is to use a
proxy or virtual private network to connect to the site.
Ultrasurf
for Windows has been designed to circumvent Internet censorship. Once
you have unpacked the program on your system you can start it right away
to start using it immediately. The portable nature makes it ideal for
situation where you cannot install software, in Internet cafes for
instance.
Unlike virtual private networks that encrypt all of the
PCs communication, UltraSurf concentrates on the web browser
exclusively. It works with several web browsers out of the box,
Microsoft’s Internet Explorer for instance or Firefox. The developer
site still states that it only works in IE automatically, and that users
of Firefox, Opera or Chrome need to change the local proxy in the
browser to make use of UltraSurf. Firefox on the other hand worked fine
on the test system without initial configuration.
Once
you launch the application it is active right away. This is indicated
with a golden lock in the lower right corner of the screen. You can
right-click the lock to bring up a context menu leading to the program’s
options
When you open the options you see two windows coming up.
First the connection window highlighting the current connection and
speed of that connection, and then the options window where changes to
the program settings can be made.
You can change the local listening port, automatic deletion of cookies and the history, or hotkey support in the options.
The
connection speed is sufficient for light web surfing, but not for
heavier use like streaming video or audio, or online gaming. It may
sometimes be necessary to switch from one server to another if the
connection speed drops to much. It is also important to note that the
encrypted connection will only be available in the web browser, and not
for other applications connecting to the web.
Ultrasurf uses a different approach than comparable applications such as GPass or Tor.
That’s not necessarily a bad thing, but it may not be enough for users
who would also like to use encryption when they retrieve their emails,
use Skype or instant messengers.
Windows users can download the latest version of Ultrasurf from the developer website.
