Après leur coup d'Etat, les militaires se sont dit prêts à censurer Internet. Mais une technologie permettant de créer des réseaux décentralisés existe. Le couvre-feu menace Internet en Thaïlande. L'armée, qui a pris hier le pouvoir après une crise de plusieurs mois, a averti qu'elle bloquerait les contenus circulant sur les réseaux sociaux qui « inciteraient à la violence ». A quelques milliers de kilomètres de Bangkok, dans la baie de San Francisco, l'équipe d'une jeune start-up assiste à des « pics » de téléchargements en Thaïlande de son produit phare : FireChat. Le premier a eu lieu le 16 mai, le second hier, témoigne Micha Benoliel, cofondateur d'Open Garden, qui édite l'application.
I had heard about mesh networking before I arrived in Somaliland, but had never been in the position to actually build a mesh network. When I accepted the position as ICT instructor at Abaarso School of Science and Technology in Abaarso, Somaliland, I figured this may be my chance. I knew that the Open Technology Institute (OTI) had been developing a mesh firmware called Commotion, suitable for remote locations. Upon arriving in Somaliland I decided that building a mesh network using Commotion would be one of my top priorities
Voilà un projet fort intéressant qui vient de voir le jour dans la ville de Sayada, gouvernorat de Monastir. CLibre, association locale qui vise la promotion de la culture du Libre, et les habitants de Sayada viennent d’installer un réseau Wifi gratuit dans toute la ville. Plusieurs routeurs/amplificateurs ont été placés dans certains points de Sayada afin d’avoir une couverture optimale du réseau, que ce soit dans la rue ou à l’intérieur des maisons. Le projet porte le nom de MeshSayada.
We are a group of volunteers building a community mesh network in Oakland, California.
How to help!
A mesh network is, in essence, free as in freedom alternative internet. Using low-cost routers (often donated or recycled) mounted on rooftops, we're currently building the backbone of the mesh throughout downtown Oakland, from West Oakland to the Fruitvale BART and beyond!
Mesh networks are awesome because they don't depend on the existing centralized Internet Service Providers to function. Though they can be connected to the Internet as we know it now, a mesh network provides a decentralized mode of communication with our local community. We view mesh networks as a means of connecting to our neighbors, supporting local businesses, and enabling grassroots community collaboration. In the event of disaster or government censorship, an active mesh network is a resilient means of communication and sharing of information.
WHILE MESH networks were created to solve an economic problem, it turns out they also have a starkly political element: They give people—particularly political activists—a safer and more reliable way to communicate.
As activism has become increasingly reliant on social networking, repressive regimes have responded by cutting off internet access. When Hosni Mubarak, for instance, discovered that protesters were using Facebook to help foment dissent, he ordered the state-controlled ISPs to shut down Egypt's internet for days. In China, the Communist Party uses its "Great Firewall" to prevent citizens from reading pro-democracy sites. In the United States, authorities have shut down mobile service to prevent activists from communicating, as happened a couple of years ago during a protest at San Francisco subway stations. And such reactions aren't only prompted by dissent. Some of the big phone and cable companies have begun to block digital activities they disapprove of, like sharing huge files on BitTorrent. In 2009, the recording industry even persuaded France to pass a law—since declared unconstitutional—that canceled the internet service of any household caught downloading copyrighted files more than three times.
Our objective is to create a versatile, decentralized network built on secure protocols for routing traffic over private mesh or public internetworks independent of a central supporting infrastructure.
Hyperboria is a global decentralized network of "nodes" running cjdns software. The goal of Hyperboria is to provide an alternative to the internet with the principles of security, scalability and decentralization at the core. Anyone can participate in the network by locating a peer that is already connect

Voici mon retour sur le "International Summit for Community Wireless", affectueusement désigné sous l'acronyme IS4CW et sous le site web wirelesssummit.org. Je vais présenter un sommaire des projets les plus intéressant que j'ai retenu, en priorisant les projets qui sont les plus pertinents pour nous (à Réseau Libre). C'est une analyse fort technique mais qui, j'espère, pourra s'avérer être une référence utile pour la communauté réseau (francophone!) de Montréal mais aussi d'ailleurs dans le monde. Il s'agit bien sûr qu'un aperçu d'un moment dans le développement de tous ces projets et les choses vont probablement changer avec le temps!
Byzantium is a live Linux distribution that delivers easy-to-use, secure, and robust mesh networking capabilities.
Babel hackathon, at LeLoop, on 19-21 July 2013. A hackathon dedicated to the Babel wireless mesh routing protocol will be held during three days in Paris, at the LeLoop.org hackerspace. The event primarily aims at testing the new features of Babel (diversity, RTT metric, source-specific routing, etc...) in a real-world environment.
Réseau Libre est un regroupement informel de bénévoles qui vise à créer un réseau sans fil communautaire et de voisinage, indépendant et décentralisé. Le réseau se construit de façon organique et évolutive à mesure que de nouveaux membres s'y joignent. Chaque personne participant au réseau installe une antenne sur son toit, ou dans sa fenêtre (un noeud) et choisit les services qu'il désire partager avec la communauté, connexion internet ou non.
Babel is a loop-avoiding distance-vector routing protocol for IPv6 and IPv4 with fast convergence properties. It is based on the ideas in DSDV, AODV and Cisco's EIGRP, but is designed to work well not only in wired networks but also in wireless mesh networks.
Our objective is to create a versatile, decentralized network built on secure protocols for routing traffic over private mesh or public internetworks independent of a central supporting infrastructure.
Hyperboria is a decentralised network established with the prinicples of freedom and security at its core.
Please keep posts relevant to network discussion, websites and services on hyperboria, ect...
Links with this logo are only available over CJDNS. If it doesn't load for you check that cjdns is running. This is just a small list of Hyperboria domains I compiled, if yours isn't in there message the mods and we'll add it ASAP.

Why Medium isn’t the answer and how to use the Internet.
Distributed everything
So I’ve illustrated the problem. Now I want to talk about a few of the solutions I’ve discovered in the past few years of pulling my own shots.
CJDNS + Hyperboria. There are around 100 people living and working on another Internet called Hyperboria. It’s based on a mesh networking router called CJDNS. If you get someone to peer you in, you’ll discover another Internet that’s a whole lot freer than this one. Visit Project Meshnet
IRC. Everyone who wants to make sure their messages land use IRC as a backchannel now.
Duckduckgo. The search engine that gets you out of your filter bubble, and respects your privacy.
Pump.io. The creator of Identi.ca has a new federated social network called Pump. Visit him at e14n.com
Host your own web server. Get your own VPS (Digital Ocean is only $5 a month) and host your own web server. Deploy using Node.js using Bitters.
When in doubt, start by learning some Internet basics. HTML5 and CSS3 are a good start for anyone who’s never learned how to code. Then move on to JavaScript and the other favorite languages of the Internet.
We’re not going to get through this by pushing buttons on centralized services.
If you want to use the Internet in 2013, you need to pick up some tech skills. In a few years this will probably be all figured out and no one will be intercepting your iMessages.
Until then, let’s send everyone a strong message by deleting our accounts on centralized services and learning how to use the distributed Internet.
Mesh networking allows users to form their own networks without a centralized infrastructure, making them inherently resistant to censorship, surveillance, and disruption. Given recent revelations showing widespread surveillance of the phone calls and online activities of innocent Americans and others around the globe, the development of mesh networks more important than ever. Governments and commercial actors have taken advantage of intermediaries as “weak links” in order to censor, surveil, and disrupt communications and social movements. Already in the United States, cell towers have been deactivated in response to planned protest, while activists in countries such as Egypt, Libya, and Syria have suffered massive blackouts that shut down all access from within the country to the wider Internet. Mesh networking technology can help activists fight back.
Our objective is to create a versatile, decentralized network built on secure protocols for routing traffic over private mesh or public internetworks independent of a central supporting infrastructure.
The goal of Byzantium is to develop and maintain a distribution of Linux which can run from removable media (such as a CD-ROM, DVD-ROM, or USB storage device) without needing to be installed. This distribution of Linux will include a graphical desktop, a control panel application which configures and manipulates services running on the Byzantium node, and mesh routing software which allows the creation of an entirely separate wireless Internet, functionally indistinguishable from a wireless access point of the sort that you’d find in a coffee shop or at home.
The Byzantium mesh network is theoretically uncensorable because it operates in a peer-to-peer fashion and avoids the existing infrastructure of the Net; any computer with a wireless network interface can become a part of the Byzantium mesh. Moreover, every Byzantium node comes with a number of collaboration and communication applications pre-installed, configured, and optimized for use by mobile clients (such as smartphones and MP3 players), from a wiki to a web-chat application to a collaborative word processor. Each application can be individually turned on and off so a particular Byzantium node doesn’t have to run everything all of the time, only the mesh routing software.
We will also write an ebook and translate it into different languages which explains how Byzantium works in a manner which is easy to understand, how to set up Byzantium nodes without our distribution of Linux, how to protect yourself if you’re running a node, and how to solve some of the thornier non-software problems (such as bridging meshes over distances longer than the unaugmented maximum range of 802.11a/b/g/n). While it would be great if we could include a FabFi kit in every .iso image it’s kind of hard to zip up an improvised antenna and cable set sitting on a workbench, so the best we can do is include and attribute the plans so you can build one yourself (at least until general purpose nanoassembly is perfected and we can include free/libre greyprints for one).
Digital media and network technologies are now part of everyday life. The Internet has become the backbone of communication, commerce, and media; the ubiquitous mobile phone connects us with others as it removes us from any stable sense of location. Along with this, the public is transforming. The mass media and mass audience analyzed by the Frankfurt School are long past. Today we inhabit multiple, overlapping and global networks such as user forums, Facebook, Flickr, blogs, and wikis. The media industry which just a decade ago seemed well-established, is in flux, facing its greatest challenge ever.
Our book, Networked Publics examines the ways that the social and cultural shifts created by these technologies have transformed our relationships to (and definitions of) place, culture, politics, and infrastructure.
