21 <p>Between <a href="#Locations">early July</a> and the <a |
|
22 href="#Locations">middle of August</a> 2010 the participants in the networking |
|
23 for communications challenged communities (<a href="http://www.n4c.eu/">N4C</a>) |
|
24 project will be providing <a href="#Email">email</a> and <a href="#Web">limited |
|
25 web services</a> in some <a href="#Locations">locations</a> in Padjelanta. |
|
26 Given that there are no normal Internet connections in the area, we will be |
|
27 using <a href="#Work">Delay-Tolerant Networking</a> (DTN) in order to provide |
|
28 these services. That means that an email sent from Staloluokta will travel on |
|
29 the next suitable helicopter to Ritsem from where it will be forwarded to the |
|
30 Internet. Based on our experience from 2009, we expect on average such an email |
|
31 will take about 15 hours to get from Staloluokta to its destination. Similarly, |
|
32 a response email from the Internet is likely to take another 15 hours to get |
|
33 back to Staloluokta. The limited web services we will be providing include |
|
34 content regularly pushed from the Internet as well as the ability to request |
|
35 specific web pages. As with the email service, delays will be measured in hours |
|
36 or days, depending on the location, helicopter movements and the availability |
|
37 of power.</p> |
|
38 |
|
39 <p>Note that this is an experimental deployment - the service is not guaranteed |
|
40 in any respect, and you use it at your own risk.</p> |

45 <td><h2>How Does it <a name="Work" id="Work">Work</a>?</h2> |
|
46 |
|
47 <p>We have developed a solar-powered WiFi hotspot that we call a "village |
|
48 DTN router" (pictured on the right). You can use this just like your home |
|
49 wireless access point if you have a WiFi enabled device. (SSID="n4cvillage", no |
|
50 security). These devices include mail and web servers (start at <a |
|
51 href="http://village.n4c.eu/">http://village.n4c.eu/</a> if you're not here |
|
52 already) where these instructions and more can be accessed.</p> |
|
53 |
|
54 <p>Since these devices are solar-powered, they will sometimes turn themselves |
|
55 off to conserve battery power. Current plans call for the devices to be |
|
56 turned off from 22:00 until 06:00 local time, and also whenever the |
|
57 battery level is too low. There is a small screen on the village DTN |
|
58 router (inside the window) that displays the current state, which |
|
59 for example, will indicate when the device will next reboot, if it is in |
|
60 a low-power state. (When the device is turned off, it will not provide |
|
61 any services:-)</p> |
|
62 |
|
63 <p>Please don't tamper with these devices - as you can imagine it can |
|
64 take a lot of effort to go visit one to fix it!</p> |
|
65 |
|
66 <p>We have installed equipment on two <a |
|
67 href="http://www.fiskflyg.se/english.asp">Fiskflyg</a> helicopters that can |
|
68 transfer messages between these village DTN routers and gateway devices |
|
69 installed at Ritsem. That is how emails and web content move between the remote |
|
70 sites and the Internet.</p> |
|
71 |
|
72 <p>The technology used for these transfers is called <a |
|
73 href="http://www.dtnrg.org/">Delay-Tolerant Networking</a> and is being used |
|
74 for trials like this one and for a range of other applications.</p> |

81 <p>Current plans call for village DTN routers to be installed as listed below. Note that dates may vary somewhat and that even locations are subject to |
|
82 change, as the trial proceeds.</p> |
|
83 <ul> |
|
84 <li>Ritsem: from July 1st to September 30th</li> |

|
91 |
|
92 <p>For most services, messages from the Internet are delivered to all |

93 locations. So if you send a mail from Ritsem and someone answers that mail, |
|
94 then you should be able to see the response when you access the mail service |
|
95 later on in, for example, Staloluokta (if enough time has passed of |
|
96 course.)</p> |

152 How you configure this depends on your client, but there are many |

153 web pages that explain this, for example: <a |

154 href="http://mail.google.com/support/bin/answer.py?hl=en&answer=13287">http://mail.google.com/support/bin/answer.py?hl=en&answer=13287</a>. |
|
155 Note that if your password is something you use elsewhere, then you really |
|
156 should turn on the TLS or SSL security options. |
|
157 </li> |
|
158 |
|
159 <li>Once your mail account is setup and working, you can choose to |
|
160 set up mail forwarding from any other mail account you have, for example |
|
161 from a gmail or Yahoo! account. Note that we cannot do that, so you need |
|
162 to figure that part out yourself. </li> |

|
169 <p>Full instructions for using the mail service may be found <a |

170 href="http://village.n4c.eu/mailhelp">here</a>. (TBD)</p> |
|
171 |
|
172 <h2><a name="Web" id="Web">Web</a> Services</h2> |
|
173 |
|
174 <p>To use the web service you need a WiFi-enabled <a href="#devices">device</a> with a standard browser.</li> |
|
175 |
|
176 <p>There are two ways to get at web pages - each day we <a |
|
177 href="#pushed">push</a> some content to each of the village DTN routers, and |
|
178 you can access that content as if you were browsing the web normally. You can |
|
179 also <a href="#requested">request</a> content we don't push to be specially |
|
180 delivered. Note however, that only fairly "static" web content really works |
|
181 well either way - rich web applications cannot currently be used via our |
|
182 service since they generally depend on a "real" Internet connection.</p> |
|
183 |
|
184 <h3><a name="pushed" id="pushed">Pushed</a> Web Content</h3> |
|
185 |
|
186 To access "pushed" web content, you simply browse to the usual places and our |
|
187 web infrastructure will serve up the web pages, if they are present. Since we |
|
188 clearly cannot copy the entire web, only a limited set of pages are available. |
|
189 Mostly, those are news, weather and other local sites that we expect to be of |
|
190 interest. For a list of the sites that are available, go to <a |
|
191 href="http://village.n4c.eu/indexofsites.html">http://village.n4c.eu/indexofsites.html |
|
192 </a>. If you would like us to add a site, please send us an email at <a |
|
193 href="mailto:help@village.n4c.eu">help@village.n4c.eu</a> and we'll try to add |
|
194 that to the list (no guarantees though!). Be as specific as you can about the |
|
195 content you'd like (many sites use complex active scripts that won't work well |
|
196 in a trial like ours). |
|
197 |
|
198 <h3><a name="requested" id="requested">Requesting</a> Specific Pages</h3> |
|
199 |
|
200 <p>To request a specific web page, you can use our <a |
|
201 href="http://village.n4c.eu/webrequest">web request portal</a>, which allows |
|
202 you to enter a web site address (a URL). We will then send that to an automated |
|
203 web engine which will attempt to get those pages and send them back to you. Of |
|
204 course, this will take quite some time, so is only really suitable if you will |
|
205 be in the area and able to use the network for a few days at least. This |
|
206 service works best if your browser accepts "cookies," in which case, it is |
|
207 possible to make a request where only you get to see the results. The default |
|
208 is that pages you request this way will be available to anyone who tries to |
|
209 access them. (Though they will not be "indexed" on our list of sites.)</p> |
|
210 |
|
211 <h2><a name="devices" id="devices">Client Devices</a></h2> |
|
212 |
|
213 <p>Most WiFi enabled devices with mail and web clients should work. We have |
|
214 used the following devices successfully with the village DTN routers. Your |
|
215 mileage may vary!</p> |
|
216 |
|
217 <ul> |
|
218 <li>Asus EEE PC 901 netbook</li> |
|
219 <li>iPhone 3G</li> |
|
220 <li>Lenovo thinkpad</li> |
|
221 </ul> |
|
222 |
|
223 <p>We are considering providing some laptops or other client devices for shared |
|
224 use in some of our locations for some of the time, so do ask if you'd like to |
|
225 use the system, but don't have a device with you, and we'll help if we can.</p> |
|
226 |
|
227 <p>We are also investigating the provision of a web-mail front-end for the mail |
|
228 service, for devices that have a browser but no mail client. We'll provide more |
|
229 details on that once we've done some testing.</p> |

|
259 <h2><a name="privacy" id="privacy">Privacy, Security etc.</a></h2> |
|
260 |
|
261 <p>Since this is an experimental deployment, we do record lots about what |
|
262 happens in the network. For mail users, that means that we could, in principle, |
|
263 read your emails, just like any other Internet service provider could. For web |
|
264 users, that means that we could track the pages you read, just like most |
|
265 Internet service providers actually do. However, we will do neither.</p> |
|
266 |
|
267 <p>We will destroy any private or personally identifying information within a |
|
268 year of the end of the trial, and we will never make any such information |
|
269 public in any form. Any scientific papers or other publications resulting from |
|
270 the trial will only include statistics and we will ensure that any such |
|
271 statistics are anonymized to the fullest extent possible.</p> |
|
272 |
|
273 <p>However, you use this experimental network at your own risk, and there |
|
274 is always the possibility that our network, or machines on our network |
|
275 could be hacked. While we do endeavour to secure our network, machines |
|
276 and data, this is not a production network, so users should not use this |
|
277 network for sensitive data, such as banking details, etc. Users should |
|
278 also not re-use passwords from other systems that may be more sensitive.</p> |
|
279 |
|
280 <p>As a mail user, you will only ever receive emails from us relating |
|
281 to the operation of the network but such mails will never request your |
|
282 password. We do plan to send an email after the trial, giving a one |
|
283 week warning that the mail servers will be decommissioned to any users who |
|
284 request such a warning. The purpose of this mail is to give users a |
|
285 chance to retrieve any messages from our servers that they might wish |
|
286 to keep for later.</p> |
|
287 |
|
288 <p>We do not have a formal acceptable use policy, however, our network |
|
289 has very limited capacity and could be susceptible to congestion should |
|
290 users attempt to email videos from the trial area or to download |
|
291 video, so we reserve the right to delete anything that causes a |
|
292 problem for the network, including for example larger emails or |
|
293 illegal content should we become aware of such. This is an |
|
294 experimental network and depends on users behaving well, so please |
|
295 do not abuse the system! (Thanks:-)</p> |
