  32         <p>The last few days I came across a few good causes that should get
  33 wider attention.  I recommend signing and donating to each one of
  34 these. :)</p>
  35
  36 <p>Via <a href="http://www.debian.org/News/weekly/2013/18/">Debian
  37 Project News for 2013-10-14</a> I came across the Outreach Program for
  38 Women program which is a Google Summer of Code like initiative to get
  39 more women involved in free software.  One debian sponsor has offered
  40 to match <a href="http://debian.ch/opw2013">any donation done to Debian
  41 earmarked</a> for this initiative.  I donated a few minutes ago, and
  42 hope you will to. :)</p>
  43
  44 <p>And the Electronic Frontier Foundation just announced plans to
  45 create <a href="https://supporters.eff.org/donate/nsa-videos">video
  46 documentaries about the excessive spying</a> on every Internet user that
  47 take place these days, and their need to fund the work.  I've already
  48 donated.  Are you next?</p>
  49
  50 <p>For my Norwegian audience, the organisation Studentenes og
  51 Akademikernes Internasjonale Hjelpefond is collecting signatures for a
  52 statement under the heading
  53 <a href="http://saih.no/Bloggers_United/">Bloggers United for Open
  54 Access</a> for those of us asking for more focus on open access in the
  55 Norwegian government.  So far 499 signatures.  I hope you will sign it
  56 too.</p>

  77         <p>Wireless mesh networks are self organising and self healing
  78 networks that can be used to connect computers across small and large
  79 areas, depending on the radio technology used.  Normal wifi equipment
  80 can be used to create home made radio networks, and there are several
  81 successful examples like
  82 <a href="http://www.freifunk.net/">Freifunk</a> and
  83 <a href="http://www.awmn.net/">Athens Wireless Metropolitan Network</a>
  84 (see
  85 <a href="http://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region#Greece">wikipedia
  86 for a large list</a>) around the globe.  To give you an idea how it
  87 work, check out the nice overview of the Kiel Freifunk community which
  88 can be seen from their
  89 <a href="http://freifunk.in-kiel.de/ffmap/nodes.html">dynamically
  90 updated node graph and map</a>, where one can see how the mesh nodes
  91 automatically handle routing and recover from nodes disappearing.
  92 There is also a small community mesh network group in Oslo, Norway,
  93 and that is the main topic of this blog post.</p>
  94
  95 <p>I've wanted to check out mesh networks for a while now, and hoped
  96 to do it as part of my involvement with the <a
  97 href="http://www.nuug.no/">NUUG member organisation</a> community, and
  98 my recent involvement in
  99 <a href="https://wiki.debian.org/FreedomBox">the Freedombox project</a>
 100 finally lead me to give mesh networks some priority, as I suspect a
 101 Freedombox should use mesh networks to connect neighbours and family
 102 when possible, given that most communication between people are
 103 between those nearby (as shown for example by research on Facebook
 104 communication patterns).  It also allow people to communicate without
 105 any central hub to tap into for those that want to listen in on the
 106 private communication of citizens, which have become more and more
 107 important over the years.</p>
 108
 109 <p>So far I have only been able to find one group of people in Oslo
 110 working on community mesh networks, over at the hack space
 111 <a href="http://hackeriet.no/">Hackeriet</a> at Husmania.  They seem to
 112 have started with some Freifunk based effort using OLSR, called
 113 <a href="http://oslo.freifunk.net/index.php?title=Main_Page">the Oslo
 114 Freifunk project</a>, but that effort is now dead and the people
 115 behind it have moved on to a batman-adv based system called
 116 <a href="http://meshfx.org/trac">meshfx</a>.  Unfortunately the wiki
 117 site for the Oslo Freifunk project is no longer possible to update to
 118 reflect this fact, so the old project page can't be updated to point to
 119 the new project.  A while back, the people at Hackeriet invited people
 120 from the Freifunk community to Oslo to talk about mesh networks.  I
 121 came across this video where Hans Jørgen Lysglimt interview the
 122 speakers about this talk (from
 123 <a href="https://www.youtube.com/watch?v=N2Kd7CLkhSY">youtube</a>):</p>
 124
 125 <p><iframe width="420" height="315" src="https://www.youtube.com/embed/N2Kd7CLkhSY" frameborder="0" allowfullscreen></iframe></p>
 126
 127 <p>I mentioned OLSR and batman-adv, which are mesh routing protocols.
 128 There are heaps of different protocols, and I am still struggling to
 129 figure out which one would be "best" for some definitions of best, but
 130 given that the community mesh group in Oslo is so small, I believe it
 131 is best to hook up with the existing one instead of trying to create a
 132 completely different setup, and thus I have decided to focus on
 133 batman-adv for now.  It sure help me to  know that the very cool
 134 <a href="http://www.servalproject.org/">Serval project in Australia</a>
 135 is using batman-adv as their meshing technology when it create a self
 136 organizing and self healing telephony system for disaster areas and
 137 less industrialized communities.  Check out this cool video presenting
 138 that project (from
 139 <a href="https://www.youtube.com/watch?v=30qNfzJCQOA">youtube</a>):</p>
 140
 141 <p><iframe width="560" height="315" src="https://www.youtube.com/embed/30qNfzJCQOA" frameborder="0" allowfullscreen></iframe></p>
 142
 143 <p>According to the wikipedia page on
 144 <a href="http://en.wikipedia.org/wiki/Wireless_mesh_network">Wireless
 145 mesh network</a> there are around 70 competing schemes for routing
 146 packets across mesh networks, and OLSR, B.A.T.M.A.N. and
 147 B.A.T.M.A.N. advanced are protocols used by several free software
 148 based community mesh networks.</p>
 149
 150 <p>The batman-adv protocol is a bit special, as it provide layer 2
 151 (as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same
 152 network.  One way to think about it is that it provide a mesh based
 153 vlan you can bridge to or handle like any other vlan connected to your
 154 computer.  The required drivers are already in the Linux kernel at
 155 least since Debian Wheezy, and it is fairly easy to set up.  A
 156 <a href="http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide">good
 157 introduction</a> is available from the Open Mesh project.  These are
 158 the key settings needed to join the Oslo meshfx network:</p>
 159
 160 <p><table>
 161 <tr><th>Setting</th><th>Value</th></tr>
 162 <tr><td>Protocol / kernel module</td><td>batman-adv</td></tr>
 163 <tr><td>ESSID</td><td>meshfx@hackeriet</td></tr>
 164 <td>Channel / Frequency</td><td>11 / 2462</td></tr>
 165 <td>Cell ID</td><td>02:BA:00:00:00:01</td>
 166 </table></p>
 167
 168 <p>The reason for setting ad-hoc wifi Cell ID is to work around bugs
 169 in firmware used in wifi card and wifi drivers.  (See a nice post from
 170 VillageTelco about
 171 "<a href="http://tiebing.blogspot.no/2009/12/ad-hoc-cell-splitting-re-post-original.html">Information
 172 about cell-id splitting, stuck beacons, and failed IBSS merges!</a>
 173 for details.)  When these settings are activated and you have some
 174 other mesh node nearby, your computer will be connected to the mesh
 175 network and can communicate with any mesh node that is connected to
 176 any of the nodes in your network of nodes. :)</p>
 177
 178 <p>My initial plan was to reuse my old Linksys WRT54GL as a mesh node,
 179 but that seem to be very hard, as I have not been able to locate a
 180 firmware supporting batman-adv.  If anyone know how to use that old
 181 wifi access point with batman-adv these days, please let me know.</p>
 182
 183 <p>If you find this project interesting and want to join, please join
 184 us on IRC, either channel
 185 <a href="irc://irc.freenode.net/#oslohackerspace">#oslohackerspace</a>
 186 or <a href="irc://irc.freenode.net/#nuug">#nuug</a> on
 187 irc.freenode.net.</p>
 188
 189 <p>While investigating mesh networks in Oslo, I came across an old
 190 research paper from the university of Stavanger and Telenor Research
 191 and Innovation called
 192 <a href="http://folk.uio.no/paalee/publications/netrel-egeland-iswcs-2008.pdf">The
 193 reliability of wireless backhaul mesh networks</a> and elsewhere
 194 learned that Telenor have been experimenting with mesh networks at
 195 Grünerløkka in Oslo.  So mesh networks are also interesting for
 196 commercial companies, even though Telenor discovered that it was hard
 197 to figure out a good business plan for mesh networking and as far as I
 198 know have closed down the experiment.  Perhaps Telenor or others would
 199 be interested in a cooperation?</p>
 200
 201 <p><strong>Update 2013-10-12</strong>: I was just
 202 <a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2013-October/005900.html">told
 203 by the Serval project developers</a> that they no longer use
 204 batman-adv (but are compatible with it), but their own crypto based
 205 mesh system.</p>

 226         <p>The other day I was pleased and surprised to discover that Marcelo
 227 Salvador had published a
 228 <a href="https://www.youtube.com/watch?v=w-GgpdqgLFc">video on
 229 Youtube</a> showing how to install the standalone Debian Edu /
 230 Skolelinux profile.  This is the profile intended for use at home or
 231 on laptops that should not be integrated into the provided network
 232 services (no central home directory, no Kerberos / LDAP directory etc,
 233 in other word a single user machine).  The result is 11 minutes long,
 234 and show some user applications (seem to be rather randomly picked).
 235 Missed a few of my favorites like celestia, planets and chromium
 236 showing the <a href="http://www.zygotebody.com/">Zygote Body 3D model
 237 of the human body</a>, but I guess he did not know about those or find
 238 other programs more interesting. :) And the video do not show the
 239 advantages I believe is one of the most valuable featuers in Debian
 240 Edu, its central school server making it possible to run hundreds of
 241 computers without hard drives by installing one central
 242 <a href="http://www.ltsp.org/">LTSP server</a>.</p>
 243
