Linux websites taken down

Linux websites, including LinuxFoundation.org and Linux.com, have been pulled offline after a security breach.

It is believed to be related to the hack of the Kernel.org website that is home to the Linux Project, two weeks ago.

How Egypt Cut Off the Internet

The Basics of an Internet Connection

On the simplest of levels, your computer connects to the internet through an internet service provider (ISP) TeData, LinkDotNet.. etc. Your service provider then either connects directly to all the other internet service providers around the world or to a larger internet service provider that then connects to all the others.

When you open up your web browser and type a domain name into the address bar, say google.com, for instance your service provider sends a lightning-quick request to whichever service provider Time.com uses to make its web pages publicly available on the internet.

The computer that holds all of google.com's web pages sends a response back through its internet service provider basically saying, "Here's the web page you requested."

The Border Gateway Protocol

In order for ISPs to establish broader connections between the computers on their networks and the rest of the computers on the internet, traffic is routed through the Border Gateway Protocol (BGP). Egypt's ISPs have a certain amount of machine-readable internet protocol (IP) addresses that are used to identify connected computers across the internet, and the BGP makes the active IP addresses visible to the rest of the world to facilitate connections.

The Border Gateway Protocol (BGP) routing table routes have been taken offline in Egypt

What BGP does is 'advertise' the local address prefixes to neighboring networks. Wholesale ISPs propagate their customer's advertisements to their neighbors so that eventually all ISPs know all other ISPs' prefixes. This enables routers to know where to send packets with a given destination address. The 3,500 Egyptian prefixes are now no longer advertised, so they're missing from the routing tables of BGP routers around the world. This means that routers no longer know where to send packets addressed to IP addresses that fall within these prefixes—even if all the cables are still working fine.

There are 3 projects underway to effectively create a government-less Internet.

The necessity of this is illuminated by recent events in Egypt, which include the government “shutting down the Internet.”

One possible option, discussed by geeks for years, is the creation of wireless ad-hoc networks, to eliminate the need for centralized hardware and network connectivity.

we're seeking projects that are specifically aimed at replacing or augmenting the public Internet.

Below few projects working to create such networks.

Openet

Openet is a part of the open_sailing project. Openet’s goal is to create a civilian Internet outside of the control of governments and corporations. It aims to not only create local mesh networks, but to build a global mesh network of mesh networks stitched together by long range packet radio.

Netsukuku

Netsukuku is a project of the Italian group FreakNet MediaLab. Netsukuku is designed to be a distributed, anonymous mesh network that relies only on normal wireless network cards. FreakNet is even building its own domain name architecture.

OPENMESH

Not to be confused with the mesh networking hardware vendor of the same name, OPENMESH is a forum created by venture captalist Shervin Pishevar for volunteers interested in building mesh networks for people living in conditions where Internet access may be limited or controlled.

Egypt Developers - fucking Idiots
