Have Internet Access When Your Government Shuts It Down

 

Internet-dialup

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. As we’ve seen in Egypt,
that means that your Internet connection can be the first to go.~ PCWorld

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.

Do-It-Yourself Internet With Ad-Hoc Wi-Fi

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).

This means
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.

Advanced freedom fighters can set up a portal Web page on their
network that explains the way the setup works, with Daihinia
instructions and a local download link so they can spread the network
even further.

Lastly, just add a Bonjour-compatible chat client like Pidgin or iChat, and you’ll be able to talk to your neighbors across the city without needing an Internet connection.

Back to Basics

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.

Unfortunately, such dial-up numbers can also be fairly easily shut down
by the Egyptian government, so you could also try returning to FidoNet–a
distributed networking system for BBSes that was popular in the 1980s.

FidoNet is limited to sending only simple text messages, and it’s
slow, but it has two virtues: Users connect asynchronously, so the
network traffic is harder to track, and any user can act as the server,
which means that even if the government shuts down one number in the
network, another one can quickly pop up to take its place.

You could also take inspiration from groups that are working to
create an ad-hoc communications network into and out of Egypt using Ham Radio,
since the signals are rarely tracked and extremely hard to shut down
or block.

Most of these efforts are still getting off the ground, but
hackers are already cobbling together ways to make it a viable form of
communication into and out of the country.

Always Be Prepared

In the land of no Internet connection, the man with dial-up is
king. Here are a few gadgets that you could use to prepare for the day
they cut the lines.

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.

In 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.

Patrick Miller hopes he isn’t first against the wall when the revolution comes. Find him on Twitter or Facebook–if you have a working Internet connection, anyway.

David Daw is an accidental expert in ad-hoc networks since his apartment gets no cell reception. Find him on Twitter or send him a ham radio signal.
