How to Bypass a Firewall or Internet Filter(2)
Steps
Host a PHP Proxy
1.On an unblocked computer, find a free PHP Host like Bravenet. Make sure it has FTP Support or a way to upload PHP scripts. Create an account.
2.On an unblocked computer, find a PHP Proxy script. There are many available and is usually just one file.
3.Upload the PHP Proxy script to your PHP Host and test it by executing the script from your browser.
4.To use it just type in the address of your script in your school.
5.As an example: If you went to Bravenet, your host might be youngone.bravenet.com. Upload your proxy i.e. "snake.php", and execute it by going to "youngone.bravenet.com/snake.php". That's it.
Disable the blocker
1.Some schools use proxy services (such as Bess) to do the filtering. It may be possible to disable it by going into Internet Explorer and choosing Tools>Internet Options>Connections Tab>Lan Settings and unchecking the "Use a proxy server for your LAN". It can be reenabled prior to leaving. In the likely event that this ability is disabled, one can use a registry editor to change the value of "HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionInternet SettingsProxyEnable" to 0.
2.Hit the go button and you will get to your favorite site!
3.Check the sites that are blocked on your local computer. Open Internet Explorer, and select Tools -> Internet Options. Click the "Security" tab and choose "Restricted Sites". The "Sites" button will become available. Be sure that the site you wish to access is not listed, if it is, highlight and delete it.
4.Lower the settings for your Internet security. This is not recommended for long periods of use, as this is how viruses and copycat programs infiltrate computers.
5.Install a filter-removing program. Many of these programs bypass the filter that is stopping you from accessing Myspace.com. Installing and using these programs may get you in serious trouble with your school or employer.
Browse using UltraSurf
Uses self invented GIFT system with a high encryption standard (Claims to be higher than financial transaction security standards)
1.Click on the link.
2.Download the Ultrasurf 8 client software (in zipped format).
3.Unzip the software using either Winzip or WinRAR.
4.Ultrasurf is a green software and doesn't require installation. Simply execute t U[version].exe example: U86.exe, U87.exe
5.The software will try to connect to proxy servers and will open a default web page in your default browser upon successful connection.
6.The software will work on any installed browsers.
7.If you can't download it from school, put the executable on a flash drive at home and run it off there.
Browse with a "Portable" Browser
This one works if the school uses a special browser with the restrictions built into it, or third-party software to restrict common browsers such as Internet Explorer on Windows, or Safari on MacOS.
1.Visit mozilla.com mozilla.com or the site of another browser such as Opera.
2.Search for a portable version of the browser. This should be a download with a "pre-installed" copy of the browser, using regular files to store settings.
3.Run the portable version and enjoy.
4.Set an http proxy in the portable browser if needed. Visit Proxy list for daily updated proxies.
Browse with remote access
1.Leave a computer always on at home (and connected to the internet). Turn on remote access.
2.On the school computer go to Start -> Accessories -> Remote Desktop Connection. Put in your IP address (or sign up your computer at home for dyndns.org to get a name for it if your address changes all the time). You can connect to your home computer, and do anything you want from there.
3.You can also use a VNC service.
Browse with text editors
If the school has blocked the download of portable browsers, you can always open the website in a text editor(e.g. Notepad.exe) and save it as a HTML file and open it later with a proper internet browser(e.g. IE or FF).
1.Open notepad. Start menu > programs > accessories > notepad OR %SystemRoot%system32notepad.exe
2.File > Open and in the "File Name" field, enter the IP address of the website you'd like to visit WITH the http:// or https:// prefixes. (See above for procedure to attain IPs.)
3.File > Save As and save the file as an .html file. Open it in MS WORD as a HTML Webpage. (you can directly download the file with MS WORD but some schools block MS OFFICE from all network access as PowerPoint used to be able to browse folders the user was not authorized to access as it ran in Shell 0 instead of Shell 1.)
