Free anonymity software for linux

Claros Anonymity is a servlet that allows anonymous browsing. It acts like a proxy, hiding the end users IP.
Claros Anonymity also enables the user to bypass a URL/IP based corporate firewall, as the requests are all directed to the machine running the servlet.
Installation:
For Tomcat Users :
Copy the war file to $TOMCAT_INSTALL_DIR/webapps folder
Start Tomcat
For other application servers, you shall know what to do with a war file. If war extension means nothing to you, just unzip is it, if it was a regular zip archive.
Claros Anonymity is an out of box application and no configuration is needed. If you want further assistance details are bundled with the readme.txt file.
Enhancements:
- Many bugs have been fixed.
- HTML Forms are working.
- HTTP POST is also supported.
- There is a brand new modern look and feel.

Incognito Live CD/USB CD provides software to use various Internet technologies while keeping the user anonymous. The project is based primarily on Tor while including supporting applications. The target use case is that of using a public computer, such as in a library, securely.

This CD may also be copied to a USB drive to provide persisted user settings. The intended user base are those who would like to perform standard Internet communications such as WWW, mail, IRC, IM, etc, while being confident that their anonymity is not compromised. Power users who want precise control over the application and network configuration may be disappointed.

There are full and tiny versions of the CD. The tiny version is intended to fit on small media and basically provides an anonymous web browser. The full version supports a variety of Internet applications.

The Gentoo Catalyst release build tool is used to build the CD. This tool is designed to make the CD easy to maintain. For an update of only Tor it takes a simple version bump and 30 minutes for the tiny CD, two hours for the full version. Human effort is minimal, Catalyst does most of the work. A full update of all software takes several hours to compile, but this is seldom done or needed and again generally requires little human effort. Adding or removing software to/from the CD is also generally trivial.

The following applications are kept up to date as soon as possible. Others may be updated sooner if a major security problem occurs (Firefox, etc.)

*Tor
*TorK
*Vidalia
*Privoxy
*Mixminion

Remaining applications, including the base system, will be updated on a roughly two month schedule.

Magellan Metasearch is a modular meta search engine, enabling users to monitor as many search engines as they want.
Magellan Metasearch provides a complex query language with standard boolean operators, meta-operators (to search through pages metadata), and proximity operators.
This language enables users to perform far more complex queries than what common search engines currently support. It can be fed any custom sources, since its abstraction layer manages the search results and their meta tags in a uniform way.
In conjunction with the local process scheduler (such as "cron"), Magellan enables you to save your requests and replay them later automatically; new results are sent through email and RSS in realtime. Magellan also provides full anonymity through smart multi-proxy support.
Enhancements:
- This release enhances the automated parsing mechanism ; it also fixes a problem with small result sets that occasionally couldnt be extracted.
- Moreover, new virtual sources are automatically tested on creation / update to check their validity.

Freenet software lets you publish and obtain information on the Internet without fear of censorship. To achieve this freedom, the network is entirely decentralized and publishers and consumers of information are anonymous. Without anonymity there can never be true freedom of speech, and without decentralization the network will be vulnerable to attack.
Communications by Freenet nodes are encrypted and are "routed-through" other nodes to make it extremely difficult to determine who is requesting the information and what its content is.
Users contribute to the network by giving bandwidth and a portion of their hard drive (called the "data store") for storing files. Unlike other peer-to-peer file sharing networks, Freenet does not let the user control what is stored in the data store. Instead, files are kept or deleted depending on how popular they are, with the least popular being discarded to make way for newer or more popular content. Files in the data store are encrypted to reduce the likelihood of prosecution by persons wishing to censor Freenet content.
The network can be used in a number of different ways and isnt restricted to just sharing files like other peer-to-peer networks. It acts more like an Internet within an Internet. For example Freenet can be used for:
Publishing websites or freesites
Communicating via message boards
Content distribution
Unlike many cutting edge projects, Freenet long ago escaped the science lab, it has been downloaded by over 2 million users since the project started, and it is used for the distribution of censored information all over the world including countries such as China and the Middle East.
Ideas and concepts pioneered in Freenet have had a significant impact in the academic world. Our 2000 paper "Freenet: A Distributed Anonymous Information Storage and Retrieval System" was the most cited computer science paper of 2000 according to Citeseer, and Freenet has also inspired papers in the worlds of law and philosophy. Ian Clarke, Freenets creator and project coordinator, was selected as one of the top 100 innovators of 2003 by MITs Technology Review magazine.
Enhancements:
- This release operates over UDP rather than TCP.
- It can transparently operate through firewalls.
- The core architecture and algorithm have been redesigned for simplicity and efficiency.
- A new and even simpler API allowing the rapid development of third party software that interacts with Freenet has been added.

ROCKate is a LiveCD, a complete operating system that operates without installing it on a harddisk. It focuses on giving people a chance to protect their privacy on the Internet. The LiveCD achieves this goal by using the Tor network for anonymity and delivers all applications pre-configured to use it.
Main features:
- Privoxy/Tor for access to the Tor network
- Xorg for a Graphical User Interface
- IceWM as Window Manager
- dillo as webbrowser
- irssi as IRC Client
ROCKate not only focuses on making it possible to be anonymous on the Internet, it also aims to make it convenient.
Every file on the filesystem is writable! This distincts ROCKate from most other LiveCD systems. This goal is achieved by using Clifford Wolfs shadowfs. The limit to this is the amount of RAM you have in your system.
Enhancements:
- The distribution is now installable to harddisk!

ZNC is an IRC bouncer with many advanced features like detaching, C++/Perl module support, multiple users, multiple clients per user, channel/query playback buffers, SSL, transparent DCC bouncing, party line, and Web administration.
Main features:
Detaching
- ZNC will stay on IRC even while you are offline.
Multiple Users
- You can add additional users under one running process. Useful for public shells that limit background processes.
Multiple Clients
- Connect to the same user with as many clients as you want.
Playback Buffers
- Stay up-to-date with what happened while you were detached.
SSL
- Encryption for both the listen port and connecting to IRC servers.
DCC Bouncing
- Transparent bouncing for DCC anonymity.
Perl Modules
- Dynamically load Perl Modules which make use of the powerful features of ZNC and make IRC use even more fun. Write your own features in the easy-to-learn Perl
- language!
C++ Modules
- Dynamically loaded shared objects. Just derive from CModule and overload any needed functions such as OnPrivMsg(). IRC scripting in C++, what could be better than that?
Partyline
- Using the global partyline module, you can join channels and query users on the internal ZNC network
Web Administration
- Using the global webadmin module, admins can add/remove/edit users and global settings and non admins can edit their own user settings.
Enhancements:
- Various bugs were fixed.
- Disabled channels were added to the core.
- The server password is now prompted for if the client doesnt send one.
- Timestamps were added to the backlog.
- A ConnectDelay config option was added.
- Basic traffic stats, usermodes support, a JoinTries per-user config option for rejoins on kick/ban, and new antiidle and nickserv modules were added.
- The API was broken (CModule::OnLoad got an extra parameter).
- Fixed channels were added to the partyline module.
- The configure script now fails if it cant find OpenSSL or Perl.
