Using non-censoring proxy servers
You can put a proxy server between your Internet connection and the site you want to visit. You send your request for a special website to that proxy server, which request the page from the Internet and deliver it to you. Normally, those servers cache the requested pages, so that on the next request he can deliver the page directly from the cache. That would be faster and cheaper. We use those servers to bypass censorship. For the eyes/computers of our ISP/Government we are only connecting to the proxy, they can't easily see, that we are connecting to a "bad site". But sometimes the standard proxy ports (80, 1080, 3128 and 8080) are blocked. In that case you have to use the proxies that are listening on an uncommon port.

Standard proxy
Standard Proxies you can find everywhere on the net. Almost every provider offer a proxy for their customers. Here are a few, its in the widely spread "hostname:port" format. These proxies are mostly not anonymous!

Planetlab CoDeeN Project (http://codeen.cs.princeton.edu/ - Very fast, you can also use them on port 3127. No POST allowed, so you only can view/download webpages and use simple forms that use the GET method (like search engines) but you can not use bigger forms that use POST (like buy stuff at Amazon)).

Uncommon port proxy
Due to the fact that several censors block the common proxy ports (80, 1080, 3128 and 8080) to prevent circumvention you have to use proxies that are listening on a uncommon port. For example 8000 for the Junkbuster proxy or 6588 for the AnalogX proxy. You get a weekly updated list of Proxies that are listening on a non standard port here: http://www.web.freerk.com/proxylist.htm

Special proxy / tunnel tools
JAP
JAP is a free and open source anonymity tool invented by Dresden University in Germany. JAP sends your traffic encrypted through several different "mixes," or intermediaries, in a predetermined sequence called a "mix cascade." The number of connections to these intermediaries makes it impossible for anyone from either the outside or from within the service itself to determine what sites a connected user has visited unless all of the intermediaries were involved in discovering this information. This makes it a very valuable tool to circumvent censorship.

Hopster
Hopster is a commercial tool to circumvent firewalls in schools, companies etc. The free version is only limited to a 4kb/s transfer rate (speed of a 56k modem). Just download the <1 MB Setup file and install it. It will test your connection/firewall and than configure everything automatically. Unlimited version costs 2 or 5 dollars a month.

Using a Web-2-phone service
This are services which you dial with a normal telephone. Then you say the website you want to visit and the operator/computer voice is reading the content to you.

Using a webproxy
Webproxies are server-side scripts that download a website onto the server and then display the information to your computer. Although you are, in fact, connecting to another site your firewall or proxy will only see a connection to the server with the script. Examples of server-side languages capable of running webproxies are CGI and PHP.
Some services, such as listed in section 3.6, are meant to act as translators, html-checkers or web archives but can also be used as webproxies. These webproxies can be used for "quick 'n dirty" bypassing because you don't have to configure your browser or add any other software or hardware. However, these types can be slower than other methods and sometimes display websites with some broken links and/or images. Only proxies that use a secure connection can be used for phrase filtering, but the others perform URL/IP filtering fine.
If you have webspace with cgi compatibility, you can download the CGIProxy from James Marshall and install it. Installation information can be found here. Alternatively, you can install it on a PC you own and access it from another computer over the internet. Instructions can be found here.

Get webpages via eMail
Several years ago when the Internet connections where slow and the "www" just invented, many people just got a to email restricted access to the Internet. That's the origin of the "Agora" and "www4email" software. Some of these email robots are still available and we can use them to bypass Internet censorship. The best thing would be to subscribe to a free email provider which allows SSL-connections (like https://www.fastmail.fm/, https://www.ziplip.com/, https://www.hushmail.com/, https://www.safe-mail.net/, https://www.mail2world.com/, https://www.webmails.com/ e.t.c) and use that account with the email addresses below. I put the field where you have to input the URL in brackets. It still works great for text. But sure there are big problems with images or even DHTML, JavaScript, Java, Flash e.t.c. Also other services besides www are possible, for a very good tutorial on this see ftp://rtfm.mit.edu/pub/usenet/news.answers/internet-services/access-via-email. There is also a web based service under http://www.web2mail.com/. I again used www.web.freerk.com/c/ as an example because the URL is all time accessible and the '.com' in the original Google address is often considered as a .com DOS-file by some computers and censorship systems. The www4mail software (http://www.www4mail.org/) is newer than the Agora software. A eMail with just "help" in the subject line will get you a tutorial on howto use the service properly.

Using steganography
Hide content inside of images.
More Info: http://www.encyclopedia-online.info/Steganography
Camera/Shy
Camera/Shy is the only steganographic tool that automatically scans for and delivers decrypted content straight from the Web. It is a stand-alone, Internet Explorer-based browser that leaves no trace on the user's system and has enhanced security.
Camera/Shy is an application that enables stealth communications, such software can be useful in countries where Email communications are regularly monitored and censored, such as happens in China.

Using a special proxy like p2p program
There are different projects of peer-2-peer programs to bypass censorship. They work like Napster, Kazaa and eDonkey, which means that you have to download a little tool that contains a server and a client part.
Peek a Booty
The goal of the Peekabooty Project is to create a product that can bypass the nationwide censorship of the World Wide Web practiced by many countries.
Peekabooty uses a complicated communications system to allow users to share information while revealing little about their identity. When a node receives a request for a web page it randomly decides whether to pass this on or access the page itself. It also only knows the address of its nearest partner. This makes it difficult to determine who requested what information and is designed to protect users from anyone trying to infiltrate the system from inside.
More info: http://www.peek-a-booty.org/
Freenet
Freenet is the oldest and most widely spread P2P-program to beat censorship, so a lot of people use it and its actually working since several years quite well. There is no access to the Internet possible through the Freenet client. You can only view/download stuff from the 'free net'. You install the client as a local proxy which is listening on port 8888 and can access links like 'http://localhost:8888/SSK@fjfkHAbxdwMyTMFgtZjcP2ge-AYPAgM/sites/fwhh/index.html' It looks like a kind of normal URL. The 'localhost:8888' addresses the proxy server on port 8888 that is running on your local machine the rest is something like an encrypted file name. It is not possible to determine who put some information into the network or who is downloading it.

TriangleBoy
Safeweb, a company that received funding from In-Q-Tel, the CIS's centure fund, released software called "Triangle Boy". The software is a peer-to-peer application that volunteers download onto their PC's. A User that has been denied access to any website by a censor can use the Triangle Boy software to circumvent the censorship. Currently the Triangle Boy software only provides access to the Voice of America, because this service is blocked by the Chinese government.

Special Services
Other services than the www.
Usenet
The normal port for newsservers 119 is usually blocked, so you have to access the Usenet via a different port. If you only sometimes want to read some very common newsgroups you can easily visit them via free web-based newsservers like http://groups.google.com/, http://news.spaceports.com/, http://wnews.easyusenet.com/wnews-free.cgi and http://www.news2web.com/. A lot of newsserver companies offer their services on a non standard port. Just ask them before signup. If you need access to a newsserver with your newsclient you have to subscribe to one of these newsserver-companies which allow access to their newsservers on an uncommon port:
http://www.giganews.com/ - (news.giganews.com on ports 23 and 80)
http://www.teranews.com/ - (news.teranews.com on ports 23, 25 and 7501)
http://www.easynews.com/ - (proxy.news.easynews.com on 22, 23, 53, 80, 110 and 443, or try their web-based service at members.easynews.com port 81)
http://www.newscene.com/ - (proxy.newscene.com on ports 20, 21, 22, 23, 25, 53, 80, 81, 110, 443 and 8080)
http://www.supernews.com/ - (news.supernews.com on any port you like)
http://www.octanews.com/ - (news.octanews.com on any port you like)
http://www.readfreenews.com/ - (news.readfreenews.net and allnews.readfreenews.net at port 80 and 120
Note: all traffic is unencrypted, so you can access these newsservers, but the censors can easily monitor all your traffic! It would be more secure to use a SSH port forwarding.

Instant Messenger
Instant Messenger are very popular. You have to register your nickname at one of the companies and download their software. Then when you are in the Internet you can start the software and log onto their servers. Since then you are marked as "online" and all your friends who know your nickname and get the same Instant Messenger can see that you are online and easily chat with you. Every of the 4 big players has its own software client which contain advertisement, spyware and is not compatible with other IM protocols. I recommend you to download Miranda, which is a open source Instant Messenger which is very small, without ads or spyware and working without installation. It works great with every IM protocol, even at the same time. http://miranda-im.org/

Howto publish information
The one think is to access information that is already censored, but the other challenge is to publish own information that can't easily be censored. Here you can see my ideas on how to avoid censorship:
Publish with a lot of mirrors. Especially dynamic IP's with a dyndns.org redirector are useful. Put your pages on so much different servers that the censors can't get along with blocking al the servers. Fax Polling. You can either use a service in the Internet or provide that service on your own computer with a fax modem. Use one-time-addresses. These are links/URL's that are only valid for 1 visit or 1 hour, they are often used for payed downloads. Hide the 'dangerous' content. For example save text as images. The users won't notice it, but its difficult for the censor-spiders to 'read' the content. Host on a secure server in another country. For example with http://www.havenco.com/ which is located at Sealand, an independent country on a little island in the north sea near England. Encrypt the content. Use .htaccess and/or SSL for your website and AES, Twofish or Rijndael for files. Offer your data in P2P-Programs. Filesharing programs like Kazaa or eDonkey are very difficult to censor (see the problems of the music companies...) Send content via eMail. Create a autoresponder from which everybody with a hotmail account can receive your content from. Martus. It's a encrypted bulletin service to post and view informations.
