How to bypass web filters


There are several occasions where you will be at a public to bypass web filters require access to a particular website that is blocked for some reason or another. How to bypass these restrictions is a very common question, and will be covered here.

Lets pretend for a moment that the Internet is made up of 26 websites, A-Z. The web filter blocks your browser from accessing sites X-Z, but not sites A-W. Simply make the browser think youre going to A-
W. There are a variety of ways to do this:


Proxy Servers: 
This is a list of http proxies. These sites may not be up forever, so you may need to search for free http proxy or public proxy servers or other similar terms.

Proxy server lists:



Now that you have a list of proxies, you would open IE (internet explorer) and click on Tools > Internet Options > Connections > LAN Settings > Advanced. Enter the address and port of one of the servers from the list in the proper area (http) and make sure the “use a proxy server for your LAN option is selected. Remember to replace the proxy and port at your terminal to the original when you're done.

*Note: Some proxies listed may not work, and this method may decrease your surfing speed. By trying various entries, you’ll find one that works, or works faster.

The infamous translation trick:
Go to a web page translation site and use their services to “translate a page to English thus accessing the blocked page through their trusted site.

You'll notice that several translation sites are blocked, but by using less popular ones, this method can still be effective. Here is a list of some translation services. Again, these sites may not be up forever, so you may need to search for them.




Url Scripting:


Url scripting is the easiest method. It works on a select few web filters and is based on the same principal as the translation trick. By typing and address like “www.yahoo.com@www.restricted_site.com the filter will not go into effect as it recognizes the trusted site (in this case yahoo.com)

Other tricks:
Simply open the command prompt and type:
Ping restricted.com ? restricted.com obviously being the restricted site
At this point you can take down the IP address (ex. 216.109.124.73) and enter it into the browser. If access to the command prompt is also restricted, see “How to bypass restrictions to get to the command prompt.” If this article has been taken from information leak, then know that it involves anything from opening the browser, selecting view > source, then saving it as X.bat and opening it to opening a folder or browser and typing in the location of cmd.exe depending on the OS. I will not go into further, as this a completely different topic.

Use https://restrictedsite.com as referring to it as a secured site may confuse the filter.

Note: These are ancient methods that many new filters defend against, but still may be applicable in your situation. If not, a little history never hurt anyone.

Web based Proxies:
Another one of the easier, yet effective methods include web based proxies. These are simple in the fact that you just enter the restricted address and surf! Some of these have some restrictions, like daily usage limits, etc but you can also use another proxy (perhaps one that sucks, like a text only) to bypass their restrictions as well. Here is a list of some:




Proxy Programs:
There are many proxy programs that allow you to surf anonymously that are more or less based on the same topics we’ve covered here. I’ve added them just to cover the topic thoroughly:



Making your own CGI proxy server:

Making your own proxy server may come in handy, but I personally find that simply uploading a txt file/w a list of proxies to a free host makes for a much easier and headache free solution. If you don't know PERL, there is code out there to help you set it up. Check out these sites for more info:

http://www.manageability.org/blog/stuff/open-source-personal-proxy-servers-written-in-java/view]http://www.manageability.org/blog/stuff/op...en-in-java/view



Admin Access:
When all else fails, you can simply take over the PC and alter or delete the damn filter. This method varies according to the OS (operating system) you are dealing with. Please see Hacking Windows NT for more information. If this tutorial has been taken from information leak, then I will go as far as to say it involves booting the PC in another OS, copying the SAM file and cracking it using a program like saminside or LC5 rather than start a whole new topic within one.

The Difference Between Flash and Shockwave



The Difference Between Flash and Shockwave

Flash and Shockwave software applications cover a lot of the same ground, and they are produced by the same company, but there are a few significant differences. Most of these are directly related to the origins of the two file formats. Director, the software application used to create Shockwave files, has been around for a long time, longer than the Internet in its current form. It was originally developed to create dynamic content for CD-ROMs, and it is still used for this purpose. As dynamic content has become more popular on the Internet, however, updated versions of Director have included more features that tailor Shockwave files for use on the Web.


they are both from the same company/manufacturer. 
they are both a platform which are used for making visual material optionally mixed with external data from the backend. 
they are both plugins for web browsers. 
they both make use for ActiveX in web browsers.
However, when I thought and thoroughly researched over it, I found a lot of differences - mainly minor ones which a joe user would not know about. So lets sort them out:

Flash 



Flash, on the other hand, was built from the ground up for use on the Web. Macromedia adapted Flash from Future Splash Animator, a vector art animation program. Macromedia's version was tailored specifically for transmission over phone line connections. So at their heart, Flash and Shockwave have two different specialties. Consequently, they have a number of contrasting strengths and weaknesses:
Flash files load more quickly than Shockwave files.


Flash is more universal. More than 90 percent of Web users have the Flash plug-in installed, while a little less than 60 percent have the Shockwave plug-in.
Flash creation software is cheaper. Director costs a little less than $1,000, while Flash costs about $400.
Flash is an open-source format. Anybody can see how it works and is free to adapt it for their own purposes. Director uses a compiled file format, so it is extremely difficult to modify the program.
With each software update, the two formats move closer and closer together




  • Is much more widespread. 
  • More on the "looking good" side. 
  • Loads faster. 
  • Can be made with several programs. 
  • Is used by many designers/developers. 
  • Is cheaper to master (Macromedia Flash costs near $400). 
  • Requires you to draw each frame by hand (unless you duplicate a frame into another key-frame). 
  • Doesn't require much technical knowledge. 
  • Works in the .SWF Flash Format. 
  • Is on the 'simple' scripting level.

Shockwave 



Shockwave is more versatile. You can create more complex games, more elaborate interactivity and more detailed animation.
You can use more types of files with Shockwave. You could, for example, import a Flash file into a Shockwave movie, but it doesn't work the other way around.
Shockwave has better Web capability with each version, and Flash gets more versatile. Eventually, the two formats will probably be merged into one comprehensive format that encompasses the best qualities of each.



  • Is not as well known as Flash. 
  • Requires some technical knowledge. 
  • Can only be created using Macromedia Director. 
  • Is much more expensive to master (Director costs more than $1,000). 
  • Has the ability to move around objects (precisely, vector images) as opposed to drawing each one in key-frames. 
  • Is on an advanced scripting language. 
  • Works in the .DCR Shockwave format. 
  • Can integrate Flash into its own format and not vice versa. 
  • Uses a type of compilation and is much more harder to decode/modify. 
  • Is mostly used for online games and things that require programming (as opposed to simple video clips or animations).

What is HTML5

What is HTML5, and Why Should You Care?


What is HTML5?

We're sure by now you've heard the term "HTML5" thrown around by the likes of Apple and Google. This is the next evolution of HTML, or Hyper Text Markup Language, which forms the backbone of almost every site on the Internet. HTML4, the last major iteration of the language, debuted in 1997 and has been subsequently poked and prodded so that it can handle the demands of the modern Web. 

Why is it such a big deal?

HTML 4 has been tweaked, stretched and augmented beyond its initial scope to bring high levels of interactivity and multimedia to Web sites. Plugins like Flash, Silverlight and Java have added media integration to the Web, but not without some cost. In search of a "better user experience" and battery life, Apple has simply dropped support for some of these plugins entirely on mobile devices, leaving much of the media-heavy Internet inaccessible on iPads and iPhones. HTML5 adds many new features, and streamlines functionality in order to render these processor-intensive add-ons unnecessary for many common functions. 

Assuming content providers sign on (and many are), this means you won't have to worry about installing yet another plugin just to listen to a song embedded in a blog or watch a video on YouTube. Similarly, this is a big deal for platforms that either don't support Flash (e.g., iPhone and iPad), or have well documented problems with it (e.g., Linux). It will be a particular boon to those smartphones for which supporting Flash has proven problematic.

So what exactly can it do?

HTML5's most touted features are media playback and offline storage. With HTML4, sites usually have to reach for Flash (or Silverlight) to simply show a video or play music. HTML5 lets sites directly embed media with the simple HTML tags "

The other major addition that has garnered media attention is the ability to store offline data for Web apps. One of the major roadblocks in the march to replace traditional desktop apps has been that the Web-based ones are useless without an Internet connection. Google developed a stopgap solution with Gears, but that product has been retired as the company is shifting its focus to HTML5. This will mean being able to create files in Google Docs or draft e-mails when away from an Internet connection. These changes would be automatically synced the next time you're online.

HTML5 also adds new interactivity features, like drag-and-drop, that have already found their way into Gmail.

How can I take advantage of it now?

Most likely, you're already taking advantage of it without knowing. Safari (both mobile and desktop), Google Chrome and Firefox 3.6 all support at least some elements of HTML5. (Internet Explorer 8's support for HTML5 is very limited.) And many Google products already use some features of the next-generation protocol. If you're using Safari or Chrome, you can check out an experimental version of YouTube that makes use of HTML5's video features. Gmail and Google Reader have adopted parts of the standard, as well. Additionally, any site listed here as being "iPad ready" is making extensive use of HTML5, including The New York Times, CNN and CBS. The latter of which recently announced it would be phasing out Flash in favor of HTML5 for all video content. If you want to dig a little deeper, you can check out a series of experiments from Mozilla that show just what HTML5 can do, and these design roundups show off what it brings to the table for designers and typographers.

Flash won't be going away anytime soon, of course; it's still widely used and supported, and those Flash-based games that we love so much are impossible to recreate using HTML. But it's important to know that when you hear people tossing about the phrase "HTML5," it isn't just some meaningless buzz word; they're talking about the future of the Internet.
