A large number of office going people face a problem accessing social networking site like orkut, myspace etc from office or workplaces since they have been blocked by the corporate firewall. There are a number of ways to bypass the firewall that is your corporate office has installed. Some of the ways to bypass the Firewall to access blocked sites depend on how powerful the firewall is. Depending the weakness of the firewall installed you can use these hacks, tips to bypass the firewall. Some of them are really easy some require you to install some kind of software. There are a number of ways to go about all of them have been outline here. 1. Using Google services to bypass a firewall to access blocked sites In this hack we try to exploit Google’s Translation service to bypass the firewall to access orkut. If you notice the url it is translating from English to English. Use the given link below and try logging in to orkut. http://www.google. com/translate? langpair= en|en&u=www.orkut. com sometimes the link may break out from the frame example when you initially login into Orkut. It might redirect you back to http://www.orkut. com in which case again use the given link above. Next is using the Google Mobile Search to access blocked Websites. http://www.google. com/xhtml This is not a great option since it displays them as it would look like when you are viewing them on a mobile phone. Also it strips out all the javascript content and CSS scripts and breaks a longer page into several smaller pages. Example http://www.google. com/gwt/n? u=clazh.blogspot .com 2. Using a Proxy Server For bypassing Firewalls at office. First find a “proxy server.” Simply search the internet for “proxy servers”. (Even a good proxy server might not work later. Therefore, learn how to find them. For these instructions, we will use an actual proxy server in Taiwan with the technical specs “address 139.223.199. 194” and “port 8080”. Try these links List of Proxies A directory of free web-based proxy services and A Directory of free proxy servers ) Then proceed as follows: Internet Explorer 6.0 1. On the Tools menu in Internet Explorer, click Internet Options, click the Connections tab, and then click LAN Settings. 2. Under Proxy server, click to select the Use a proxy server for your LAN check box. 3. In the Address box, type the IP address of the proxy server. 4. In the Port box, type the port number that is used by the proxy server for client connections (by default, 8080). 5. You can click to select the Bypass proxy server for local addresses check box if you do not want the proxy server computer to be used when you connect to a computer on the local network (this may speed up performance) . 6. Click OK to close the LAN Settings dialog box. 7. Click OK again to close the Internet Options dialog box. 3. Using IP resolution to bypass weak firewalls to access blocked sites BlockedThis is for all those pathetic souls out there who are sad and worried sitting in their office cubicle behind a firewall/filter, which has rendered your dear old orkut inaccessible Smile! Well, just as something to do with my free time today as my brain was unable to solve a bug in my current code, I decided to break open the filter settings of orkut being inaccessible Smile! Pre-requisites * Need to keep trying and trying hard @ breaking stuff * A lil bit know-how of using computers… Essentially the mantra of Ctrl+C and Ctrl+V * Ability to browse That’s right – anybody with the basics of browsing can break open the filter for orkutting Principle behind the breaking This section can be skipped by the people who are not interested in learning why you can break open a filtered site! Essentially what your filter is checking for is the domain name to be blocked. IOW, the filter would search for ur HTTP header for the domain name to be say http://www.orkut.com and will block any headers from proceeding to the website Smile! Now, how can we hack this? The answer is much simpler than it seems actually. At least for my case, I just replaced the domain name by its corresponding IP address. For e.g. the time when I wanted to access orkut.com I went to Convert Host Name to IP Address or Find IP address of a host – e.g. find IP address of host name of and found out the IP address of http://www.orkut.com Replace the http://www.orkut.com occurrence in the URL on your web-address by the corresponding IP. Boom, everything starts working!! Instructions specific to accessing orkut With orkut you require a little bit more patience… IP Address Step 1: Get the IP address of orkut.com from here, and let’s say it’s named X.X.X.X Step 2: Type http://www.orkut. com/GLogin. aspx?done= http%3A%2F% 2Fwww.orkut. com%2F and replace “www.orkut.com” with the IP address you have located. So, the address should be http://X.X.X.X/GLogin.aspx? done=http% 3A%2F%2FX.X.X.X%2F Replaced URL Step 3: This would lead you to another blocked page, wherein the site address on the top/or the URL that was blocked needs to be retrieved… Usually it’s of this type – http://www.orkut. com/RedirLogin. aspx?page= http://www. orkut.com/ Home.aspx? xid=::weirdnumbe rhere:: New URL Login screen A ray o hope? Step 4: Replace http://www.orkut.com with the IP address and the ::weirdnumberhere: : with your unique XID [Everybody has a unique id], and click on enter. Replaced New URL You are through, pathetic soul Smile! Tadaaa Note: Put Screenshots in!! P.S. Please if you are asking questions, gimme the exact steps you followed in the comment! Thanks P.P.S: I am not responsible for any loss of jobs, firings, hirings etc because you followed my instructions! ! Thanks and have a nice day!! Wink! 4. Using the TOR Network Tor (The Onion Router) to bypass firewall restrictions Only For Advanced users. Tor (The Onion Router) is a free software implementation of second-generation onion routing a system enabling its users to communicate anonymously on the Internet. Originally sponsored by the US Naval Research Laboratory, Tor became an Electronic Frontier Foundation (EFF) project in late 2004. The EFF supported Tor financially until November 2005 and continues to provide web hosting for the project
