How To Get DIY Internet Access When The Government Shuts It Down

(disinfo.com) In the past few weeks, we’ve seen a number of national governments shut off internet access in attempts to quash dissent. PC World has a guide on how to access the web when the powers that be are blocking it, or post-apocalypse, when telecommunation networks are in shambles. Supposedly antiquated devices such as dial-up modems may someday be direly important amid the smoking ruins of post-America:

These days, no popular movement goes without an Internet presence of some kind, whether it’s organizing on Facebook or spreading the word through Twitter. And as we’ve seen in Egypt, that means that your Internet connection can be the first to go. Whether you’re trying to check in with your family, contact your friends, or simply spread the word, here are a few ways to build some basic network connectivity when you can’t rely on your cellular or landline Internet connections.

Even if you’ve managed to find an Internet connection for yourself, it won’t be that helpful in reaching out to your fellow locals if they can’t get online to find you. If you’re trying to coordinate a group of people in your area and can’t rely on an Internet connection, cell phones, or SMS, your best bet could be a wireless mesh network of sorts–essentially, a distributed network of wireless networking devices that can all find each other and communicate with each other. Even if none of those devices have a working Internet connection, they can still find each other, which, if your network covers the city you’re in, might be all you need. At the moment, wireless mesh networking isn’t really anywhere close to market-ready, though we have seen an implementation of the 802.11s draft standard, which extends the 802.11 Wi-Fi standard to include wireless mesh networking, in the One Laptop Per Child (OLPC) XO laptop.

However, a prepared guerrilla networker with a handful of PCs could make good use of Daihinia ($25, 30-day free trial), an app that piggybacks on your Wi-Fi adapter driver to turn your normal ad-hoc Wi-Fi network into a multihop ad-hoc network (disclaimer: we haven’t tried this ourselves yet), meaning that instead of requiring each device on the network to be within range of the original access point, you simply need to be within range of a device on the network that has Daihinia installed, effectively allowing you to add a wireless mesh layer to your ad-hoc network.

Remember when you stashed your old modems in the closet because you thought you might need them some day? In the event of a total communications blackout–as we’re seeing in Egypt, for example–you’ll be glad you did. Older and simpler tools, like dial-up Internet or even ham radio, could still work, since these “abandoned” tech avenues aren’t being policed nearly as hard.

In order to get around the total shutdown of all of the ISPs within Egypt, several international ISPs are offering dial-up access to the Internet to get protesters online, since phone service is still operational. It’s slow, but it still works–the hard part is getting the access numbers without an Internet connection to find them.

Given enough time and preparation, your ham radio networks could even be adapted into your own ad-hoc network using Packet Radio, a radio communications protocol that you can use to create simple long-distance wireless networks to transfer text and other messages between computers. Packet Radio is rather slow and not particularly popular (don’t try to stream any videos with this, now), but it’s exactly the kind of networking device that would fly under the radar.

Response to the crisis in Egypt, nerds everywhere have risen to call for new and exciting tools for use in the next government-mandated shutdown. Bre Pettis, founder of the hackerspace NYC Resistor and creator of the Makerbot 3D printer, has called for “Apps for the Appocalypse,” including a quick and easy way to set up chats on a local network so you can talk with your friends and neighbors in an emergency even without access to the Internet. If his comments are any indication, Appocalypse apps may be headed your way soon.

Tons of cool tech are also just waiting to be retrofitted for these purposes. David Dart’s Pirate Box is a one-step local network in a box originally conceived for file sharing and local P2P purposes, but it wouldn’t take much work to adapt the Pirate Box as a local networking tool able to communicate with other pirate boxes to form a compact, mobile set of local networks in the event of an Internet shutdown.

Whether you’re in Egypt or Eagle Rock, you rely on your Internet access to stay in touch with friends and family, get your news, and find information you need. (And read PCWorld, of course.) Hopefully with these apps, tools, and techniques, you won’t have to worry about anyone–even your government–keeping you from doing just that.

  1. Setting up a Linux-based Open-Mesh Wireless Network, Part 1

    Mesh networks are a type of wireless network. As you’ll discover, mesh networking is great for blanketing Wi-Fi in larger areas. They are especially useful in places where the environment changes frequently, such as people and walls moving around in malls, trees and buildings growing around an apartment complex, boats moving around the docks, and trucks coming in and out of stops. Additionally, they are perfect for locations and applications where it’s hard to run network cabling…

  2. Mesh Networking (or 802.11s) comes to Linux
    http://whyamistilltyping.wordpress.com/2008/09/04/mesh-networking-or-80211s-comes-to-linux/

    Since kernel 2.6.22 there has been a huge drive to rework and update the entire wireless networking stack in Linux. Back in July, 2.6.26 was released with over 600 wifi specific changes including :

    * mac80211 now supports draft mesh networking (802.11s; thanks to the open80211s project
    * mac80211 now supports more optional HT (802.11n) features
    * mac80211′s monitor interfaces can now be configured more precisely, “cooked” monitors were added
    * mac80211′s IBSS implementation now supports IBSS merging and received various bugfixes
    * mac80211 now has an in-kernel documentation book, help welcome!
    * b43 now has support for PCMCIA devices and QoS/WME

    The following have been removed.

    * the bcm43xx driver
    * the old ieee80211softmac code

    A while ago I discussed the deprecation of the bcm43xx driver so I welcome its official removal from the kernel as this means less time wasted disabling this legacy kernel module prior to installing / activating b43 on every new install. The mesh networking (draft specification designated 802.11s) support is largly thanks to the open80211s project however it is only in the fairly early stages. Support is not consistent across all the Linux wifi drivers but full support is progressing. I do wonder whether mesh networking will take off, it is however, an exciting concept. Imagine the following scenarios:

    1. A dense build up urban area, where multiple nodes (flats / homes etc) could connect via one or two Internet connected nodes.

    2. A neighbourhood which contained a lot of like minded PC users each connecting as a node in a local mesh network to create an ‘instant’ LAN/WAN or gaming network. Imagine being about to connect Xbox 360s / PS3 / PSP or even PC gamers wirelessly to your neighbours without using the Internet services.

    3. A sparse, less developed environment where multiple nodes are greatly spread out and Internet access is rare.

    The possibilities are endless, however with all such technologies, a lot of people need to jump on the bandwagon, particularly with ad-hoc technologies such as these.
