+ <div class="body">
+ <p>I fjor sommer lagde jeg en
+<a href="http://people.skolelinux.org/pere/blog/SQL_database_med_anbud_publisert_p__Doffin.html">offentlig
+tilgjengelig SQL-database over offentlig anbud</a> basert på skraping
+av HTML-data fra Doffin. Den har stått og gått siden da, og har nå
+ca. 28000 oppføringer. Jeg oppdaget da jeg tittet innom at noen
+oppføringer var ikke blitt med, antagelig på grunn av at de fikk
+tildelt sekvensnummer i Doffin en godt stund før de ble publisert,
+slik at min nettsideskraper som fortsatte skrapingen der den slapp
+sist ikke fikk dem med seg. Jeg har fikset litt slik at skraperen nå
+ser litt tilbake i tid for å se om den har gått glipp av noen
+oppføringer, og har skrapet på nytt fra midten av september 2013 og
+fremover. Det bør dermed bli en mer komplett database for kommende
+måneder. Hvis jeg får tid skal jeg forsøke å skrape "glemte" data fra
+før midten av september 2013, men tør ikke garantere at det blir
+prioritert med det første. </p>
+
+<p>Men målet med denne bloggposten er å vise hvordan denne
+Doffin-databasen kan brukes og integreres med en RSS-leser, slik at en
+kan la datamaskinen holde et øye med Doffin-annonseringer etter
+nøkkelord. En kan lage sitt eget søk ved å besøke
+<ahref="https://classic.scraperwiki.com/docs/api?name=norwegian-doffin#sqlite">API-et
+hos Scraperwiki</a>, velge format rss2 og så legge inn noe ala dette i
+"query in SQL":</p>
+
+<p><pre>
+select title, scrapedurl as link, abstract as description,
+ publishdate as pubDate from 'swdata'
+ where abstract like '%linux%' or title like '%linux%'
+ order by seq desc limit 20
+</pre></p>
+
+<p>Dette vil søke opp alle anbud med ordet linux i oppsummering eller
+tittel. En kan lage mer avanserte søk hvis en ønsker det. URL-en som
+dukker opp nederst på siden kan en så gi til sin RSS-leser (jeg bruker
+akregator selv), og så automatisk få beskjed hvis det dukker opp anbud
+med det aktuelle nøkkelordet i teksten. Merk at kapasiteten og
+ytelsen hos Scraperwiki er begrenset, så ikke be RSS-leseren hente ned
+oftere enn en gang hver dag.</p>
+
+<p>Du lurer kanskje på hva slags informasjon en kan få ut fra denne
+databasen. Her er to RSS-kilder, med søkeordet

+ </div>
+ <div class="date">
+ 10th November 2013
+ </div>
+ <div class="body">
+ <p>Continuing my research into mesh networking, I was recommended to
+use TP-Link 3040 and 3600 access points as mesh nodes, and the pair I
+bought arrived on Friday. Here are my notes on how to set up the
+MR3040 as a mesh node using
+<a href="http://www.openwrt.org/">OpenWrt</a>.</p>
+
+<p>I started by following the instructions on the OpenWRT wiki for
+<a href="http://wiki.openwrt.org/toh/tp-link/tl-mr3040">TL-MR3040</a>,
+and downloaded
+<a href="http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin">the
+recommended firmware image</a>
+(openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin) and
+uploaded it into the original web interface. The flashing went fine,
+and the machine was available via telnet on the ethernet port. After
+logging in and setting the root password, ssh was available and I
+could start to set it up as a batman-adv mesh node.</p>
+
+<p>I started off by reading the instructions from
+<a href="http://wirelessafrica.meraka.org.za/wiki/index.php?title=Antoine's_Research">Wireless
+Africa</a>, which had quite a lot of useful information, but
+eventually I followed the recipe from the Open Mesh wiki for
+<a href="http://www.open-mesh.org/projects/batman-adv/wiki/Batman-adv-openwrt-config">using
+batman-adv on OpenWrt</a>. A small snag was the fact that the
+<tt>opkg install kmod-batman-adv</tt> command did not work as it
+should. The batman-adv kernel module would fail to load because its
+dependency crc16 was not already loaded. I
+<a href="https://dev.openwrt.org/ticket/14452">reported the bug</a> to
+the openwrt project and hope it will be fixed soon. But the problem
+only seem to affect initial testing of batman-adv, as configuration
+seem to work when booting from scratch.</p>
+
+<p>The setup is done using files in /etc/config/. I did not bridge
+the Ethernet and mesh interfaces this time, to be able to hook up the
+box on my local network and log into it for configuration updates.
+The following files were changed and look like this after modifying
+them:</p>
+
+<p><tt>/etc/config/network</tt></p>
+
+<pre>

+# option 'interfaces' 'second_mesh'
+</pre>
+
+<p>The mesh node is now operational. I have yet to test its range,
+but I hope it is good. I have not yet tested the TP-Link 3600 box
+still wrapped up in plastic.</p>

+ </div>
+ <div class="date">
+ 21st October 2013
+ </div>
+ <div class="body">
+ <p>The last few days I have been experimenting with
+<a href="http://www.open-mesh.org/projects/batman-adv/wiki">the
+batman-adv mesh technology</a>. I want to gain some experience to see
+if it will fit <a href="https://wiki.debian.org/FreedomBox">the
+Freedombox project</a>, and together with my neighbors try to build a
+mesh network around the park where I live. Batman-adv is a layer 2
+mesh system ("ethernet" in other words), where the mesh network appear
+as if all the mesh clients are connected to the same switch.</p>
+
+<p>My hardware of choice was the Linksys WRT54GL routers I had lying
+around, but I've been unable to get them working with batman-adv. So
+instead, I started playing with a
+<a href="http://www.raspberrypi.org/">Raspberry Pi</a>, and tried to
+get it working as a mesh node. My idea is to use it to create a mesh
+node which function as a switch port, where everything connected to
+the Raspberry Pi ethernet plug is connected (bridged) to the mesh
+network. This allow me to hook a wifi base station like the Linksys
+WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
+non-mesh clients to hook up to the mesh. This in turn is useful for
+Android phones using <a href="http://servalproject.org/">the Serval
+Project</a> voip client, allowing every one around the playground to
+phone and message each other for free. The reason is that Android
+phones do not see ad-hoc wifi networks (they are filtered away from
+the GUI view), and can not join the mesh without being rooted. But if
+they are connected using a normal wifi base station, they can talk to
+every client on the local network.</p>
+
+<p>To get this working, I've created a debian package
+<a href="https://github.com/petterreinholdtsen/meshfx-node">meshfx-node</a>
+and a script
+<a href="https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node">build-rpi-mesh-node</a>
+to create the Raspberry Pi boot image. I'm using Debian Jessie (and
+not Raspbian), to get more control over the packages available.
+Unfortunately a huge binary blob need to be inserted into the boot
+image to get it booting, but I'll ignore that for now. Also, as
+Debian lack support for the CPU features available in the Raspberry
+Pi, the system do not use the hardware floating point unit. I hope
+the routing performance isn't affected by the lack of hardware FPU
+support.</p>
+
+<p>To create an image, run the following with a sudo enabled user
+after inserting the target SD card into the build machine:</p>
+
+<p><pre>
+% wget -O build-rpi-mesh-node \
+ https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
+% sudo bash -x ./build-rpi-mesh-node > build.log 2>&1
+% dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
+%
+</pre></p>
+
+<p>Booting with the resulting SD card on a Raspberry PI with a USB
+wifi card inserted should give you a mesh node. At least it does for
+me with a the wifi card I am using. The default mesh settings are the
+ones used by the Oslo mesh project at Hackeriet, as I mentioned in
+<a href="http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html">an
+earlier blog post about this mesh testing</a>.</p>
+
+<p>The mesh node was not horribly expensive either. I bought
+everything over the counter in shops nearby. If I had ordered online
+from the lowest bidder, the price should be significantly lower:</p>
+
+<p><table>
+
+<tr><th>Supplier</th><th>Model</th><th>NOK</th></tr>
+<tr><td>Teknikkmagasinet</td><td>Raspberry Pi model B</td><td>349.90</td></tr>
+<tr><td>Teknikkmagasinet</td><td>Raspberry Pi type B case</td><td>99.90</td></tr>
+<tr><td>Lefdal</td><td>Jensen Air:Link 25150</td><td>295.-</td></tr>
+<tr><td>Clas Ohlson</td><td>Kingston 16 GB SD card</td><td>199.-</td></tr>
+<tr><td>Total cost</td><td></td><td>943.80</td></tr>
+
+</table></p>
+
+<p>Now my mesh network at home consist of one laptop in the basement
+connected to my production network, one Raspberry Pi node on the 1th
+floor that can be seen by my neighbor across the park, and one
+play-node I use to develop the image building script. And some times
+I hook up my work horse laptop to the mesh to test it. I look forward
+to figuring out what kind of latency the batman-adv setup will give,
+and how much packet loss we will experience around the park. :)</p>

+ <p>Wireless mesh networks are self organising and self healing
+networks that can be used to connect computers across small and large
+areas, depending on the radio technology used. Normal wifi equipment
+can be used to create home made radio networks, and there are several
+successful examples like
+<a href="http://www.freifunk.net/">Freifunk</a> and
+<a href="http://www.awmn.net/">Athens Wireless Metropolitan Network</a>
+(see
+<a href="http://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region#Greece">wikipedia
+for a large list</a>) around the globe. To give you an idea how it
+work, check out the nice overview of the Kiel Freifunk community which
+can be seen from their
+<a href="http://freifunk.in-kiel.de/ffmap/nodes.html">dynamically
+updated node graph and map</a>, where one can see how the mesh nodes
+automatically handle routing and recover from nodes disappearing.
+There is also a small community mesh network group in Oslo, Norway,
+and that is the main topic of this blog post.</p>
+
+<p>I've wanted to check out mesh networks for a while now, and hoped
+to do it as part of my involvement with the <a
+href="http://www.nuug.no/">NUUG member organisation</a> community, and
+my recent involvement in
+<a href="https://wiki.debian.org/FreedomBox">the Freedombox project</a>
+finally lead me to give mesh networks some priority, as I suspect a
+Freedombox should use mesh networks to connect neighbours and family
+when possible, given that most communication between people are
+between those nearby (as shown for example by research on Facebook
+communication patterns). It also allow people to communicate without
+any central hub to tap into for those that want to listen in on the
+private communication of citizens, which have become more and more
+important over the years.</p>
+
+<p>So far I have only been able to find one group of people in Oslo
+working on community mesh networks, over at the hack space
+<a href="http://hackeriet.no/">Hackeriet</a> at Husmania. They seem to
+have started with some Freifunk based effort using OLSR, called
+<a href="http://oslo.freifunk.net/index.php?title=Main_Page">the Oslo
+Freifunk project</a>, but that effort is now dead and the people
+behind it have moved on to a batman-adv based system called
+<a href="http://meshfx.org/trac">meshfx</a>. Unfortunately the wiki
+site for the Oslo Freifunk project is no longer possible to update to
+reflect this fact, so the old project page can't be updated to point to
+the new project. A while back, the people at Hackeriet invited people
+from the Freifunk community to Oslo to talk about mesh networks. I
+came across this video where Hans Jørgen Lysglimt interview the
+speakers about this talk (from
+<a href="https://www.youtube.com/watch?v=N2Kd7CLkhSY">youtube</a>):</p>
+
+<p><iframe width="420" height="315" src="https://www.youtube.com/embed/N2Kd7CLkhSY" frameborder="0" allowfullscreen></iframe></p>
+
+<p>I mentioned OLSR and batman-adv, which are mesh routing protocols.
+There are heaps of different protocols, and I am still struggling to
+figure out which one would be "best" for some definitions of best, but
+given that the community mesh group in Oslo is so small, I believe it
+is best to hook up with the existing one instead of trying to create a
+completely different setup, and thus I have decided to focus on
+batman-adv for now. It sure help me to know that the very cool
+<a href="http://www.servalproject.org/">Serval project in Australia</a>
+is using batman-adv as their meshing technology when it create a self
+organizing and self healing telephony system for disaster areas and
+less industrialized communities. Check out this cool video presenting
+that project (from
+<a href="https://www.youtube.com/watch?v=30qNfzJCQOA">youtube</a>):</p>
+
+<p><iframe width="560" height="315" src="https://www.youtube.com/embed/30qNfzJCQOA" frameborder="0" allowfullscreen></iframe></p>
+
+<p>According to the wikipedia page on
+<a href="http://en.wikipedia.org/wiki/Wireless_mesh_network">Wireless
+mesh network</a> there are around 70 competing schemes for routing
+packets across mesh networks, and OLSR, B.A.T.M.A.N. and
+B.A.T.M.A.N. advanced are protocols used by several free software
+based community mesh networks.</p>
+
+<p>The batman-adv protocol is a bit special, as it provide layer 2
+(as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same
+network. One way to think about it is that it provide a mesh based
+vlan you can bridge to or handle like any other vlan connected to your
+computer. The required drivers are already in the Linux kernel at
+least since Debian Wheezy, and it is fairly easy to set up. A
+<a href="http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide">good
+introduction</a> is available from the Open Mesh project. These are
+the key settings needed to join the Oslo meshfx network:</p>
+
+<p><table>
+<tr><th>Setting</th><th>Value</th></tr>
+<tr><td>Protocol / kernel module</td><td>batman-adv</td></tr>
+<tr><td>ESSID</td><td>meshfx@hackeriet</td></tr>
+<td>Channel / Frequency</td><td>11 / 2462</td></tr>
+<td>Cell ID</td><td>02:BA:00:00:00:01</td>
+</table></p>
+
+<p>The reason for setting ad-hoc wifi Cell ID is to work around bugs
+in firmware used in wifi card and wifi drivers. (See a nice post from
+VillageTelco about
+"<a href="http://tiebing.blogspot.no/2009/12/ad-hoc-cell-splitting-re-post-original.html">Information
+about cell-id splitting, stuck beacons, and failed IBSS merges!</a>
+for details.) When these settings are activated and you have some
+other mesh node nearby, your computer will be connected to the mesh
+network and can communicate with any mesh node that is connected to
+any of the nodes in your network of nodes. :)</p>
+
+<p>My initial plan was to reuse my old Linksys WRT54GL as a mesh node,
+but that seem to be very hard, as I have not been able to locate a
+firmware supporting batman-adv. If anyone know how to use that old
+wifi access point with batman-adv these days, please let me know.</p>

+<p>While investigating mesh networks in Oslo, I came across an old
+research paper from the university of Stavanger and Telenor Research
+and Innovation called
+<a href="http://folk.uio.no/paalee/publications/netrel-egeland-iswcs-2008.pdf">The
+reliability of wireless backhaul mesh networks</a> and elsewhere
+learned that Telenor have been experimenting with mesh networks at
+Grünerløkka in Oslo. So mesh networks are also interesting for
+commercial companies, even though Telenor discovered that it was hard
+to figure out a good business plan for mesh networking and as far as I
+know have closed down the experiment. Perhaps Telenor or others would
+be interested in a cooperation?</p>
+
+<p><strong>Update 2013-10-12</strong>: I was just
+<a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2013-October/005900.html">told
+by the Serval project developers</a> that they no longer use
+batman-adv (but are compatible with it), but their own crypto based
+mesh system.</p>
