Defeating national censorship barriers, enabling free and anonymous networking.

Have you grown tired of being muzzled by your internet service provider - not allowed to visit websites for political reasons? Are you in an oppressive country that blocks your access to free and open discussion of important social issues? Would you like to use computers at public internet cafes without being subject to internet filters, surveillance, spyware, or malware? Would you like to use your own operating system on public computers and leave no usage tracks and block surveillance of your activities? If yes, then "MOFO Linux" is your solution. MOFO Linux is secure, free (as in freedom and beer), and effective in penetrating "national firewalls" designed to inhibit freedom of speech. This is a tool designed to help you be in touch with anyone, anywhere there is internet service.

MOFO Linux is designed for easy usage on home PCs, laptops, and any computers installed in internet cafes around the world. Use MOFO Linux to break free of authoritarian powers intending to control the flow of information or "own the truth." As of version 4.0, MOFO Linux is built upon an Ubuntu base, with all of the latest software for productivity and entertainment.

MOFO Linux contains Encrypted DNS, OpenVPN, Softether, Tor, Freenet, and I2P, and other software tools provide anonymous and secure access to the internet and circumvention of state censorship restrictions. The system is designed for running from a bootable USB stick or "frugal install" on a hard drive / SSD. Browsing history and usage tracks are destroyed on shutdown.

Usage and installation options are many. MOFO Linux can be used as a boot disc, installed to USB or SD flash memory, or installed on a hard drive in a manner similar to other live Linux distros. A suggestion for easy portability is to install MOFO Linux to a flash drive using the included installer, UNETBOOTIN, or "DD copy method." Use it as a pocket operating system, which will boot and run well on nearly every PC one is likely to encounter.


MOFO Linux is configured with one default user account (mofo), with the ability to switch to root. There are no passwords in the default MOFO Linux distro. You may create your own password, if desired, but it is not necessary for typical usage.

LANTERN and PSIPHON (Domain Fronting Proxies)

Lantern works well in restricted internet environments. Simply find "Lantern" in the Dash application search (the top icon on the desktop launcher). Start Lantern and it will automatically connect to remote servers and provide fast, unrestricted internet access through Firefox.

Psiphon is a circumvention system effective against sophisticated state censorship stystems. Access psiphon in the Dash application search, and click to bring up the controller. Select "start" or "stop" as necessary, and the controller will handle the configuration process.


To use an Open VPN service with MOFO Linux, follow these steps:



Softether is capable of fast broadband data transfers, uses strong encryption, but is highly targeted by censorship authorities. Client software for Linux is still sparse, but MOFO Linux includes the official client plus a Softether Controller application which will partially automate the connection process.


Tor is the oldest and most well developed anonymous network, with extensive infrastructure providing strong anonymity to internet users. I2P is a new robust privacy and anonymity network. It contains quite a lot of content and services for its users, all resistant to surveillance and censorship. Freenet is an active, decentralised anonymous network designed such that it is impossible to censor and extremely resistant to surveillance. These networks contain internally reachable anonymized websites, chat areas, forums, markets, and exit nodes to the open internet.

For anonymous web browsing, use the "Tor Browser" application, found on the launcher or by entering "Tor" in the Dash search field. The Tor Browser, Tor Messenger, and OnionShare applications are fully configured for routing through Tor. If you are in China or other countries which block encryption, use the Tor bridges to defeat the blockage. Meek-Azure and Obfs4 are most effective. Tor, with Obs4proxy or Scramblesuit, may also be run separately using the "Tor Controller" application. Use the same application to shut down Tor and reconfigure Firefox for normal browsing.

For I2P, use the "I2P Controller" application, found by entering "I2P" in the Dash search field. Use the same application to shut down I2P and reconfigure Firefox for normal browsing.

In MOFO Linux, Freenet is configured to install freshly from its java package. Use the "Freenet Installer" application to set it up for the first time. To stop or restart Freenet, use the buttons within its main browser page.

Cjdns is a global, decentralised, encrypted mesh networking protocol. Hyperboria is the largest of many networks using cjdns offering a vast volume of cyberspace separate from the main internet. It is decentralised and extremely difficult to surveil or censor.


Veracrypt is the top multi-platform software for VERY STRONG file system encryption forked from Truecrypt. It has great features and performance - able to encrypt drives and directories, even hiding them from detection. It is compatible with Linux, Windows and Mac systems, so encrypted files may be created or accessed on just about any computer. Zulucrypt is a native Linux application for file and volume encryption also forked from Truecrypt.

Ecryptfs is an encrypted filesystem with support built into the Linux Kernel. It is fast, strong, and efficient enough to keep users' files safe from unwanted access. Use it to encrypt folders or whole drives which will hold sensitive data. Ecryptfs is the principal means of encrypting the home directory and other storage volumes in Linux.

It is suggested that users run MOFO Linux from a flash drive and keep a separate flashdrive partition for encrypted files. Another option is to use a separate drive and encrypt its entire contents, accessing it through Veracrypt. Doing that, it is possible to carry a large volume of data which is quite difficult to detect and even more difficult to decrypt. In theory, a well-arranged encrypted volume should be secure for centuries. Be careful to create strong passwords. Do not allow any secret keys to be compromised.


Kodi Media Center provides access to thousands of high quality video and audio streams from around the world. Extra radio stations have been added to Rhythmbox for access to news, music, and political programming. The very good Ubuntu multimedia apps are enhanced with systemwide audio equalization, compression, and limiting for extra punch in home theater / office presentation environments.


MOFO Linux defaults to English on startup, with ability to change the system to Chinese or Arabic in the Settings application. Multilanguage keyboard input is always available. To change the system language, select it in "Language support", then LOG OUT and LOG BACK IN without turning off the computer. The new language will then be activated. Language support in Firefox may be managed by using the Tools -> Addons -> Languages menu.


MOFO Linux wishes to acknowledge and thank the developers creating Ubuntu Linux, the base system upon which MOFO Linux is built. Ubuntu provides incredibly smooth operation, fast perfomance, and a pleasant user interface quite suitable for building customized systems. The developers of the many cryptographic / VPN systems used by MOFO Linux get a nod too! Without OpenVPN, Tor, RSA, SSL, and other goodies, the world would be a much less free and more dangerous place.


Creators or distributors of MOFO Linux bear no responsibility for the actions of end users. Users of MOFO Linux are responsible for their own actions and should consider legal implications of evading local and national censorship rules and take suitable measures to prevent interdiction. No guarantees or warranties are applicable to MOFO Linux; much of the software is beta, subject to countermeasures, or blocked by adversarial internet providers. Use of software in MOFO Linux is solely at the user's discretion and risk. MOFO Linux is not endorsed by or affiliated with Ubuntu / Canonical. Ubuntu is simply used as a foundation for building MOFO Linux.
