- <div class="body"><p>Here is a call for help from the Debian Edu / Skolelinux project.
-We have two problems blocking the release of the Wheezy version we
-hope to get released soon. The two problems require some with PHP
-skills, and we seem to lack anyone with both time and PHP skills in
-the project:
-
-<ol>
-
-<li>It is impossible to log into the slbackup web interface
- (slbackup-php) using the root user and password. This is
- <a href="http://bugs.debian.org/700257">BTS report #700257</a>.
- This used to work, but stopped working some time since Squeeze.
- Perhaps some obsolete PHP feature was used?</li>
-
-<li>It is not possible to "mass import" user lists in Gosa, neither
- using ldif nor using CSV files. The feature was disabled after a
- major rewrite of Gosa, and need to be ported to the new system.
- This is <a href="http://bugs.debian.org/698840">BTS report
- #698840</a>.</li>
-
-</ol>
-
-<p>If you can help us, please join us on IRC
-(<ahref="irc://irc.debian.org/%23debian-edu">#debian-edu on
-irc.debian.org</a>) and provide patches via the BTS.</p>

+2013-04-01, so I decided to wrap up a package based on the great work
+from Cajus Pollmeier and put it in a collab-maint maintained git
+repository to get a package I could use. I would very much like
+others to help me maintain the package (or just take over, I do not

- <div class="date"> 4th June 2013</div>
- <div class="body"><p>It has been a while since my last English
-<a href="http://www.skolelinux.org/">Debian Edu and Skolelinux</a>
-interview last November. But the developers and translators are still
-pulling along to get the Wheezy based release out the door, and this
-time I managed to get an interview from one of the French translators
-in the project, Cédric Boutillier.</p>
-
-<p><strong>Who are you, and how do you spend your days?</strong></p>
-
-<p>I am 34 year old. I live near Paris, France. I am an assistant
-professor in probability theory. I spend my daytime teaching
-mathematics at the university and doing fundamental research in
-probability in connexion with combinatorics and statistical physics.</p>
-
-<p>I have been involved in the Debian project for a couple of years
-and became Debian Developer a few months ago. I am working on Ruby
-packaging, publicity and translation.</p>
-
-<p><strong>How did you get in contact with the Skolelinux / Debian Edu
-project?</strong></p>
-
-<p>I came to the Debian Edu project after a call for translation of
-<a href="http://wiki.debian.org/DebianEdu/Documentation/Manuals">the
-Debian Edu manual</a> for the release of Debian Edu Squeeze. Since
-then, I have been working on updating the French translation of the
-manual.
-
-<p>I had the opportunity to make an installation of Debian Edu in a
-virtual machine when I was preparing localised version of some screen
-shots for the manual. I was amazed to see it worked out of the box and
-how comprehensive the list of software installed by default was.</p>
-
-<p>What amazed me was the complete network infrastructure directly
-ready to use, which can and the nice administration interface provided
-by <a href="https://oss.gonicus.de/labs/gosa/">GOsa²</a>. What pleased
-me also was the fact that among the software installed by default,
-there were many "traditional" educative software to learn languages,
-to count, to program... but also software to develop creativity and
-artistic skills with music (<a href="http://ardour.org/">Ardour</a>,
-<a href="http://audacity.sourceforge.net/">Audacity</a>) and
-movies/animation (I was especially thinking of
-<a href="http://linuxstopmotion.sourceforge.net/">Stopmotion</a>).</p>
-
-<p>I am following the development of Debian Edu and am hanging out on
-<a href="irc://irc.debian.org/%23debian-edu">#debian-edu</a>.
-Unfortunately, I don't much time to get more involved in this
-beautiful project.</p>
-
-<p><strong>What do you see as the advantages of Skolelinux / Debian
-Edu?</strong></p>
-
-<p>For me, the main advantages of Skolelinux/Debian Edu are its
-community of experts and its precise documentation, as well as the
-fact that it provides a solution ready to use.</p>
-
-<p>I would add also the fact that it is based on the rock solid Debian
-distribution, which ensures stability and provides a huge collection
-of educational free software.</p>
-
-<p><strong>What do you see as the disadvantages of Skolelinux / Debian
-Edu?</strong></p>
-
-<p>Maybe the lack of manpower to do lobbying on the
-project. Sometimes, people who need to take decisions concerning IT do
-not have all the elements to evaluate properly free software
-solutions. The fact that support by a company may be difficult to find
-is probably a problem if the school does not have IT personnel.</p>
-
-<p>One can find support from a company by looking at
-<a href="http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp">the
-wiki dokumentation</a>, where some countries already have a number of
-companies providing support for Debian Edu, like Germany or
-Norway. This list is easy to find readily from the manual. However,
-for other countries, like France, the list is empty. I guess that
-consultants proposing support for Debian would be able to provide some
-support for Debian Edu as well.</p>
-
-<p><strong>Which free software do you use daily?</strong></p>
-
-<p>I am using the KDE Plasma Desktop. But the pieces of software I use
-most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
-scientific documents, mpd for music. VIM is my editor of choice. I am
-also using the mathematical software
-<a href="http://www.scilab.org/en/scilab/about">Scilab</a> and
-<a href="http://www.sagemath.org/index.html">Sage</a> (built from
-source as not completely packaged for Debian, yet).
-
-<p><strong>Do you have any suggestions for teachers interested in
-using the free software in Debian to teach mathematics and
-statistics?</strong></p>
-
-<p>I do not have any "nice" recommendations for statistics. At our
-university, we use both <a href="http://www.r-project.org/">R</a> and
-Scilab to teach statistics and probabilistic simulations. For
-geometry, there are nice programs:</p>
-
-<ul>
-
-<li><a href="http://www.drgeo.eu/">drgeo</a> and
-<a href="http://edu.kde.org/applications/all/kig">kig</a> to do
-constructions in planar geometry
-
-<li><a href="http://www.geom.uiuc.edu/software/download/kali.html">kali</a>
-to discover symmetry groups (the so-called wallpapers and frieze
-groups), although the interface looks a bit old.</li>
-
-</ul>
-
-<p>I like also
-<a href="http://edu.kde.org/applications/all/cantor">cantor</a>, which
-provides a uniform interface to SciLab, Sage,
-<a href="http://directory.fsf.org/wiki/Octave">Octave</a>, etc...</p>
-
-<p><strong>Which strategy do you believe is the right one to use to
-get schools to use free software?</strong></p>
-
-<p>My suggestions would be to</p>
-
-<ul>
-
-<li>advertise the reduction of costs when free software is used.</li>

+ <div class="date">27th October 2013</div>
+ <div class="body"><p>The
+<a href="http://packages.qa.debian.org/v/vmdebootstrap.html">vmdebootstrap</a>
+program is a a very nice system to create virtual machine images. It
+create a image file, add a partition table, mount it and run
+debootstrap in the mounted directory to create a Debian system on a
+stick. Yesterday, I decided to try to teach it how to make images for
+<a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi</a>, as part
+of a plan to simplify the build system for
+<a href="https://wiki.debian.org/FreedomBox">the FreedomBox
+project</a>. The FreedomBox project already uses vmdebootstrap for
+the virtualbox images, but its current build system made multistrap
+based system for Dreamplug images, and it is lacking support for
+Raspberry Pi.</p>
+
+<p>Armed with the knowledge on how to build "foreign" (aka non-native
+architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
+code and adjusted it to be able to build armel images on my amd64
+Debian laptop. I ended up giving vmdebootstrap five new options,
+allowing me to replicate the image creation process I use to make
+<a href="http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html">Debian
+Jessie based mesh node images for the Raspberry Pi</a>. First, the
+<tt>--foreign /path/to/binfm_handler</tt> option tell vmdebootstrap to
+call debootstrap with --foreign and to copy the handler into the
+generated chroot before running the second stage. This allow
+vmdebootstrap to create armel images on an amd64 host. Next I added
+two new options <tt>--bootsize size</tt> and <tt>--boottype
+fstype</tt> to teach it to create a separate /boot/ partition with the
+given file system type, allowing me to create an image with a vfat
+partition for the /boot/ stuff. I also added a <tt>--variant
+variant</tt> option to allow me to create smaller images without the
+Debian base system packages installed. Finally, I added an option
+<tt>--no-extlinux</tt> to tell vmdebootstrap to not install extlinux
+as a boot loader. It is not needed on the Raspberry Pi and probably
+most other non-x86 architectures. The changes were accepted by the
+upstream author of vmdebootstrap yesterday and today, and is now
+available from
+<a href="http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/">the
+upstream project page</a>.</p>
+
+<p>To use it to build a Raspberry Pi image using Debian Jessie, first
+create a small script (the customize script) to add the non-free
+binary blob needed to boot the Raspberry Pi and the APT source
+list:</p>
-<li>communicate about the quality of free software projects, using
- well known examples like Firefox, ThunderBird and
- OpenOffice.org/LibreOffice.</li>
-
-<li>advertise the living and strong community around the project.</li>
+<p><pre>
+#!/bin/sh
+set -e # Exit on first error
+rootdir="$1"
+cd "$rootdir"
+cat <<EOF > etc/apt/sources.list
+deb http://http.debian.net/debian/ jessie main contrib non-free
+EOF
+# Install non-free binary blob needed to boot Raspberry Pi. This
+# install a kernel somewhere too.
+wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
+ -O $rootdir/usr/bin/rpi-update
+chmod a+x $rootdir/usr/bin/rpi-update
+mkdir -p $rootdir/lib/modules
+touch $rootdir/boot/start.elf
+chroot $rootdir rpi-update
+</pre></p>
-<li>show that it is not more difficult to use than any other
- system.</li>
+<p>Next, fetch the latest vmdebootstrap script and call it like this
+to build the image:</p>
+
+<pre>
+sudo ./vmdebootstrap \
+ --variant minbase \
+ --arch armel \
+ --distribution jessie \
+ --mirror http://http.debian.net/debian \
+ --image test.img \
+ --size 600M \
+ --bootsize 64M \
+ --boottype vfat \
+ --log-level debug \
+ --verbose \
+ --no-kernel \
+ --no-extlinux \
+ --root-password raspberry \
+ --hostname raspberrypi \
+ --foreign /usr/bin/qemu-arm-static \
+ --customize `pwd`/customize \
+ --package netbase \
+ --package git-core \
+ --package binutils \
+ --package ca-certificates \
+ --package wget \
+ --package kmod
+</pre></p>
-</ul>
+<p>The list of packages being installed are the ones needed by
+rpi-update to make the image bootable on the Raspberry Pi, with the
+exception of netbase, which is needed by debootstrap to find
+/etc/hosts with the minbase variant. I really wish there was a way to
+set up an Raspberry Pi using only packages in the Debian archive, but
+that is not possible as far as I know, because it boots from the GPU
+using a non-free binary blob.</p>
+
+<p>The build host need debootstrap, kpartx and qemu-user-static and
+probably a few others installed. I have not checked the complete
+build dependency list.</p>
+
+<p>The resulting image will not use the hardware floating point unit
+on the Raspberry PI, because the armel architecture in Debian is not
+optimized for that use. So the images created will be a bit slower
+than <a href="http://www.raspbian.org/">Raspbian</a> based images.</p>

-i Oslo</a>, en institusjon som lenge har vektlagt verdien av åpne
-standarder og fri programvare. Men noe har endret seg, og for en
-liten stund tilbake annonserte USIT at dagens fungerende e-postsystemet
-basert på fri programvare skulle byttes ut med Microsoft Exchange og
-at Microsoft Outlook skulle bli den best fungerende men antagelig ikke
-eneste støttede e-postklienten. Annonseringen har ført til flere
-protester og <a href="http://folk.uio.no/dssantos/nooutlookatuio/">en
-underskriftskampanje</a>, initiert av Diana Santos, der så langt 253
-personer har signert. Prosjektet
-<a href="http://www.usit.uio.no/prosjekter/nike/">NIKE (Ny integrert
-kalender/e-post)</a> ble initiert for å se på mulige løsninger med
-utgangspunkt i at en kombinert epost/kalenderløsning var påkrevd, og
-prosjektet
-<a href="http://www.usit.uio.no/prosjekter/nike-implementasjon/">NIKE-implementasjon</a>
-er igang med å rulle ut MS Exchange ved Universitetet i Oslo.</p>
-
-<p>For kun kort tid siden ble det annonsert at det blir et åpent møte

-
-<p>Tid: <strong>Onsdag 2013-06-05 kl. 10:00</strong>
-<br>Sted: <strong>9. etasje i Lucy Smiths hus (admin-bygget)</strong></p>
-
-<p> Det kan være en god plass å stille opp hvis en som meg ikke tror
-valget av Microsoft Exchange som sentral epostinfrastruktur er et
-heldig valg for Norges ledende forskningsuniversitet, men at en er mer
-tjent med å selv
-<a href="http://nuug.no/dokumenter/kronikk-friprog-itsikkerhet.shtml">beholde
-kontrollen over egen infrastruktur</a>.</p>

+ <div class="date">26th October 2013</div>
+ <div class="body"><p>De siste måneders eksponering av
+<a href="http://www.aftenposten.no/nyheter/uriks/Her-er-Edvard-Snowdens-mest-omtalte-avsloringer-7351734.html">den
+totale overvåkningen som foregår i den vestlige verden dokumenterer
+hvor sårbare vi er</a>. Men det slår meg at de som er mest sårbare
+for dette, myndighetspersoner på alle nivåer, neppe har innsett at de
+selv er de mest interessante personene å lage profiler på, for å kunne
+påvirke dem.</p>
+
+<p>For å ta et lite eksempel: Stortingets nettsted,
+<a href="http://www.stortinget.no/">www.stortinget.no</a> (og
+forsåvidt også
+<a href="http://data.stortinget.no/">data.stortinget.no</a>),
+inneholder informasjon om det som foregår på Stortinget, og jeg antar
+de største brukerne av informasjonen der er representanter og
+rådgivere på Stortinget. Intet overraskende med det. Det som derimot
+er mer skjult er at Stortingets nettsted bruker
+<a href="http://en.wikipedia.org/wiki/Google_Analytics">Google
+Analytics</a>, hvilket gjør at enhver som besøker nettsidene der også
+rapporterer om besøket via Internett-linjer som passerer Sverige,
+England og videre til USA. Det betyr at informasjon om ethvert besøk
+på stortingets nettsider kan snappes opp av svensk, britisk og USAs
+etterretningsvesen. De kan dermed holde et øye med hvilke
+Stortingssaker stortingsrepresentantene synes er interessante å sjekke
+ut, og hvilke sider rådgivere og andre på stortinget synes er
+interessant å besøke, når de gjør det og hvilke andre representanter
+som sjekker de samme sidene omtrent samtidig. Stortingets bruk av
+Google Analytics gjør det dermed enkelt for utenlands etteretning å
+spore representantenes aktivitet og interesse. Hvis noen av
+representantene bruker Google Mail eller noen andre tjenestene som
+krever innlogging, så vil det være enda enklere å finne ut nøyaktig
+hvilke personer som bruker hvilke nettlesere og dermed knytte
+informasjonen opp til enkeltpersoner på Stortinget.</p>
+
+<p>Og jo flere nettsteder som bruker Google Analytics, jo bedre
+oversikt over stortingsrepresentantenes lesevaner og interesse blir
+tilgjengelig for svensk, britisk og USAs etterretning. Hva de kan
+bruke den informasjonen til overlater jeg til leseren å undres
+over.</p>

+ <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>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

- <div class="date">27th May 2013</div>
- <div class="body"><p>Two days ago, I asked
-<a href="http://people.skolelinux.org/pere/blog/How_can_I_install_Linux_on_a_Packard_Bell_Easynote_LV_preinstalled_with_Windows_8_.html">how
-I could install Linux on a Packard Bell EasyNote LV computer
-preinstalled with Windows 8</a>. I found a solution, but am horrified
-with the obstacles put in the way of Linux users on a laptop with UEFI
-and Windows 8.</p>
-
-<p>I never found out if the cause of my problems were the use of UEFI
-secure booting or fast boot. I suspect fast boot was the problem,
-causing the firmware to boot directly from HD without considering any
-key presses and alternative devices, but do not know UEFI settings
-enough to tell.</p>
-
-<p>There is no way to install Linux on the machine in question without
-opening the box and disconnecting the hard drive! This is as far as I
-can tell, the only way to get access to the firmware setup menu
-without accepting the Windows 8 license agreement. I am told (and
-found description on how to) that it is possible to configure the
-firmware setup once booted into Windows 8. But as I believe the terms
-of that agreement are completely unacceptable, accepting the license
-was never an alternative. I do not enter agreements I do not intend
-to follow.</p>
-
-<p>I feared I had to return the laptops and ask for a refund, and
-waste many hours on this, but luckily there was a way to get it to
-work. But I would not recommend it to anyone planning to run Linux on
-it, and I have become sceptical to Windows 8 certified laptops. Is
-this the way Linux will be forced out of the market place, by making
-it close to impossible for "normal" users to install Linux without
-accepting the Microsoft Windows license terms? Or at least not
-without risking to loose the warranty?</p>
-
-<p>I've updated the
-<a href="http://www.linlap.com/packard_bell_easynote_lv">Linux Laptop
-wiki page for Packard Bell EasyNote LV</a>, to ensure the next person
-do not have to struggle as much as I did to get Linux into the
-machine.</p>

- <div class="date">25th May 2013</div>
- <div class="body"><p>I've run into quite a problem the last few days. I bought three
-new laptops for my parents and a few others. I bought Packard Bell
-Easynote LV to run Kubuntu on and use as their home computer. But I
-am completely unable to figure out how to install Linux on it. The
-computer is preinstalled with Windows 8, and I suspect it uses UEFI
-instead of a BIOS to boot.</p>
-
-<p>The problem is that I am unable to get it to PXE boot, and unable
-to get it to boot the Linux installer from my USB stick. I have yet
-to try the DVD install, and still hope it will work. when I turn on
-the computer, there is no information on what buttons to press to get
-the normal boot menu. I expect to get some boot menu to select PXE or
-USB stick booting. When booting, it first ask for the language to
-use, then for some regional settings, and finally if I will accept the
-Windows 8 terms of use. As these terms are completely unacceptable to
-me, I have no other choice but to turn off the computer and try again
-to get it to boot the Linux installer.</p>
-
-<p>I have gathered my findings so far on a Linlap page about the
-<a href="http://www.linlap.com/packard_bell_easynote_lv">Packard Bell
-EasyNote LV</a> model. If you have any idea how to get Linux
-installed on this machine, please get in touch or update that wiki
-page. If I can't find a way to install Linux, I will have to return
-the laptop to the seller and find another machine for my parents.</p>
-
-<p>I wonder, is this the way Linux will be forced out of the market
-using UEFI and "secure boot" by making it impossible to install Linux
-on new Laptops?</p>

- <div class="date">24th May 2013</div>
- <div class="body"><p>En ting
-<a href="http://www.skolelinux.org/">Skolelinux-prosjektet</a> har
-hatt mye glede av er studentprosjekter. F.eks. er
-<a href="http://linuxstopmotion.org/">stillbildeanimasjonssystemet
-Stopmotion</a> resultat av et studentprosjekt i Skolelinux. De siste
-månedene har en ivrig student veiledet av Marius Kotsbak i
-<a href="http://www.friprogramvareiskolen.no/">FRiSK</a> testet hva en
-kan få til med en datamaskin til NOK 400,- (antagelig 1700,- med
-skjerm, tastatur og mus) når det brukes i Skolelinux. Jeg spurte han
-om et intervju.</p>
-
-<p><strong>Hvem er du, og hva driver du med til daglig?</strong></p>
-
-<p>Jeg heter Nirosan Thiyagalingam. Jeg er 24 år og studerer
-dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
-data har siden ung alder vært tilstede og jeg har i tillegg alltid
-vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
-det alltid noe nytt å lære. Noe som igjen har gjort det svært
-interessant å følge med på utviklingen. Jeg valgte dataingeniør
-studiet grunnet ønske om å lære enda mer om programmering og utvikling
-av store systemer.</p>
-
-<p><strong>Hvordan kom du i kontakt med Skolelinux-prosjektet?</strong></p>
-
-<p>Skolelinux prosjektet hørte jeg først om i media. Men det var først
-når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
-prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
-hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
-jeg valgte derfor en oppgave som gikk ut på å få en
-<a href="http://www.raspberrypi.org">Raspberry PI</a>. Altså en
-ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
-vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
-forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
-operativsystemet Linux fungerte før jeg kunne angripe
-problemet. Prøvde først å finne ut hvordan man kunne transformere en
-vanlig installasjon av Skolelinux til Raspberry PI, men dette var
-altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
-videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
-diskutert hvilken retning jeg burde gå for å få til en fullverdig
-løsning. Det ble bestemt at jeg skulle gå for å først installere
-<a href="http://www.raspbian.org/">Raspian</a>. Dette er et
-operativsystem basert på Debian spesiallaget for Raspberry Pi sin
-maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
-å installere de nødvendige Skolelinux pakkene for å få til et
-fullverdig system. Disse pakkene ble installert manuelt i første
-omgang, men ble senere installert automatisk via et script som Petter
-Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
-gang med installasjonen i løpet av bare 5 minutter. Ikke nok med det,
-alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
-resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
-maskin og det merkes godt når man har installert Skolelinux på
-den. Video og 3D-rendering fungerer utrolig dårlig, men nettsurfing og
-kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
-datamaskinen er egnet for enkle oppgaver.
-
-<p>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
-løsning. På markedet finnes det nå maskiner som har bedre hardware enn
-Raspberry Pi. Det er store muligheter for at man kan klare å
-installere Skolelinux på disse også, og da forsvinner nok mest
-sannsynlig ytelsesproblemene med Video og 3D rendering også.</p>
-
-<p>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
-fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
-med tanke på hastighet og brukeropplevelse. Men også her var video og
-3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
-<a href="http://www.berryterminal.com/">BerryTerminal</a> for å få til
-dette.</p>
-
-<p><strong>Hva er fordelene med Skolelinux slik du ser det?</strong></p>
-
-<p>Fordelen med Skolelinux er mange. At det er gratis er en stor
-fordel, men at det er så mange som er med på å utvikle det og
-vedlikeholde det er en enda større fordel. Allerede før jeg startet
-med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
-så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
-hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
-nødvendige programmene og funksjonen som både små og store skoler i
-tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
-så komplett løsning er en kjempefordel. Installasjonen er knirkefri
-og det er svært enkelt å installere og komme i gang.</p>
-
-<p><strong>Hva er ulempene med Skolelinux slik du ser det?</strong></p>
-
-<p>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
-om websidene er enkle og konsise er det allikevel ikke appellerende i
-like stor grad som for eksempel
-<a href="http://www.ubuntu.com">Ubuntu</a> sine sider. Deres side
-tilbyr, i tillegg til godt design og presentasjon, en nettbasert
-emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
-det. Bortsett fra dette ser jeg absolutt ingen ulemper med
-Skolelinux-prosjektet.</p>
-
-<p><strong>Hvilken fri programvare bruker du til daglig?</strong></p>
-
-<p>Til daglig er jeg en flittig bruker av det åpne media
-sentersystemet <a href="http://xbmc.org/">XBMC</a>. Det enorme
-samfunnet rundt dette prosjektet har gjort dette til et program som
-dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
-tanke på utseende og funksjoner ved installere plug-ins eller
-scripts.</p>
-
-<p><strong>Hvilken strategi tror du er den rette å bruke for å få
-skoler til å ta i bruk fri programvare?</strong></p>
-
-<p>Strategien som burde brukes sett fra mine øyne er
-markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
-i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
-annet som koster de store summer. At skolelinux til de grader tilbyr
-en så komplett løsning bure komme frem. Enten via reklamekampanjer
-eller ved å sende ut folk til skoler for så å la skolenettverk
-ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
-i tillegg ble utviklet gode websider og en emulator for å la brukere
-prøve operativsystemet ville nok dette ha styrket inntrykket
-betraktelig.</p>

+ <div class="date">11th October 2013</div>
+ <div class="body"><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>If you find this project interesting and want to join, please join
+us on IRC, either channel
+<a href="irc://irc.freenode.net/#oslohackerspace">#oslohackerspace</a>
+or <a href="irc://irc.freenode.net/#nuug">#nuug</a> on
+irc.freenode.net.</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>

- <div class="date">17th May 2013</div>
- <div class="body"><p><a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> is
-an operating system based on Debian intended for use in schools. It
-contain a turn-key solution for the computer network provided to
-pupils in the primary schools. It provide both the central server,
-network boot servers and desktop environments with heaps of
-educational software. The project was founded almost 12 years ago,
-2001-07-02. If you want to support the project, which is in need for
-cash to fund developer gatherings and other project related activity,
-<a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">please
-donate some money</a>.
-
-<p>A topic that come up again and again on the Debian Edu mailing
-lists and elsewhere, is the question on how to transform a Debian or
-Ubuntu installation into a Debian Edu installation. It isn't very
-hard, and last week I wrote a script to replicate the steps done by
-the Debian Edu installer.</p>
-
-<p>The script,
-<a href="http://anonscm.debian.org/viewvc/debian-edu/branches/wheezy/debian-edu-config/share/debian-edu-config/tools/debian-edu-bless?view=markup">debian-edu-bless<a/>
-in the debian-edu-config package, will go through these six steps and
-transform an existing Debian Wheezy or Ubuntu (untested) installation
-into a Debian Edu Workstation:</p>
-
-<ol>
-
-<li>Add skolelinux related APT sources.</li>
-<li>Create /etc/debian-edu/config with the wanted configuration.</li>
-<li>Install debian-edu-install to load preseeding values and pull in
- our configuration.</li>
-<li>Preseed debconf database with profile setup in
- /etc/debian-edu/config, and run tasksel to install packages
- according to the profile specified in the config above,
- overriding some of the Debian automation machinery.</li>
-<li>Run debian-edu-cfengine-D installation to configure everything
- that could not be done using preseeding.</li>
-<li>Ask for a reboot to enable all the configuration changes.</li>
-
-</ol>
-
-<p>There are some steps in the Debian Edu installation that can not be
-replicated like this. Disk partitioning and LVM setup, for example.
-So this script just assume there is enough disk space to install all
-the needed packages.</p>
-
-<p>The script was created to help a Debian Edu student working on
-setting up <a href="http://www.raspberrypi.org">Raspberry Pi</a> as a
-Debian Edu client, and using it he can take the existing
-<a href="http://www.raspbian.org/FrontPage">Raspbian</a> installation and
-transform it into a fully functioning Debian Edu Workstation (or
-Roaming Workstation, or whatever :).</p>
-
-<p>The default setting in the script is to create a KDE Workstation.
-If a LXDE based Roaming workstation is wanted instead, modify the
-PROFILE and DESKTOP values at the top to look like this instead:</p>
-
-<p><pre>
-PROFILE="Roaming-Workstation"
-DESKTOP="lxde"
-</pre></p>
-
-<p>The script could even become useful to set up Debian Edu servers in
-the cloud, by starting with a virtual Debian installation at some
-virtual hosting service and setting up all the services on first
-boot.</p>

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

-
-<p>Debian Edu, also known as Skolelinux, is a Linux distribution based

-configured school network. Immediatly after installation a school
-server running all services needed for a school network is set up just
-waiting for users and machines being added via GOsa², a comfortable
-Web-UI. A netbooting environment is prepared using PXE, so after
-initial installation of the main server from CD, DVD or USB stick all
-other machines can be installed via the network.</p>

-not released yet). Basically this is an updated and slightly improved

+ <div class="date">29th September 2013</div>
+ <div class="body"><p>A few hours ago, the announcement for the first stable release of
+Debian Edu Wheezy went out from the Debian publicity team. The
+complete announcement text can be found at
+<a href="http://www.debian.org/News/2013/20130928">the Debian News
+section</a>, translated to several languages. Please check it out.</p>
+
+<p>There is one minor known problem that we will fix very soon. One
+can not install a amd64 Thin Client Server using PXE, as the /var/
+partition is too small. A workaround is to extend the partition (use
+lvresize + resize2fs in tty 2 while installing).</p>

+<p>On other news, I am happy to report that Freedombox based on Debian
+Jessie is coming along quite well, and soon both Owncloud and using
+Tor should be available for testers of the Freedombox solution. :) In
+a few weeks I hope everything needed to test it is included in Debian.
+The withsqlite package is already in Debian, and the plinth package is
+pending in NEW. The third and vital part of that puzzle is the
+metapackage/setup framework, which is still pending an upload. Join
+us on <a href="irc://irc.debian.org:6667/%23freedombox">IRC
