About Debian Edu and Skolelinux

- -

Debian Edu, also known as Skolelinux, is a Linux distribution based -on Debian providing an out-of-the box environment of a completely -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 GOsaÂ², 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.

- -

This is the first test release based on Wheezy (which currently is -not released yet). Basically this is an updated and slightly improved -version compared to the Squeeze release.

- -

Software updates

Install freemind (0.9.0) by default, and stop installing vym by - default.
Install chromium (26.0.1410.43) by default.
Install goplay (0.5-1.1) to make golearn available by default.
Updated support for Japanese input methods, now based on - ibus-anthy.

- -

Other changes

Switched default file system from ext3 to ext4 for speed and - reliability improvements.
Got rid of unwanted winbind daemon and PAM setup activated because - of 706434.
Extended and improved the testsuite tests to detect more possible - problems.
Corrected proxy handling to not set http_proxy to a bogus - direct:// URL.
Corrected proxy setup for diskless workstations.
Corrected PXE setup to use our updated udebs during installation.
Made installation handling of low entropy level more robust.
Create larger partitions for Roaming workstations and Thin client - servers, to make room for all the software installed.
Fix bug in Roaming workstation PAM setup, making it impossible to - log in (706753).

- -

Known issues

IP resolution for the local hostname give useless IPv6 address - (705900). Only install - libnss-myhostname on roaming workstations until it is fixed.
DVD images are not yet ready.
No mass import of user account data in GOsa (ldif or csv) - available yet (698840).
Missing artwork for the KDE desktop (and probably a few others).
KDE Debian submenu lacks icons.
LXDE menu lacks entry for changing GOsa password - (website). Installing gosa-desktop will be an option.
Backup configuration via web interface is impossible due to - password submission problem - (700257).

Browser plugin for SPICE (spice-xpi) uploaded to Debian

1st November 2013

The SPICE protocol for +remote display access is the preferred solution with oVirt and RedHat +Enterprise Virtualization, and I was sad to discover the other day +that the browser plugin needed to use these systems seamlessly was +missing in Debian. The request +for a package was from 2012-04-10 with no progress since +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 +mind), but as no-one had volunteered so far, I just uploaded it to +NEW. I hope it will be available in Debian in a few days.

+ +

The source is now available from +http://anonscm.debian.org/gitweb/?p=collab-maint/spice-xpi.git;a=summary.

Debian, the Linux distribution of choice for LEGO designers?

11th May 2013

In January, -I -announced a new IRC -channel #debian-lego, for those of us in the Debian and Linux -community interested in LEGO, the -marvellous construction system from Denmark. We also created -a wiki page to have -a place to take notes and write down our plans and hopes. And several -people showed up to help. I was very happy to see the effect of my -call. Since the small start, we have a debtags tag -hardware::hobby:lego -tag for LEGO related packages, and now count 10 packages related to -LEGO and Mindstorms:

- -

- - - - - - - - - - -
brickos alternative OS for LEGO Mindstorms RCX. Supports development in C/C++
leocad virtual brick CAD software
libnxt utility library for talking to the LEGO Mindstorms NX
lnpd daemon for LNP communication with BrickOS

Teaching vmdebootstrap to create Raspberry Pi SD card images

27th October 2013

The +vmdebootstrap +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 +Raspberry Pi, as part +of a plan to simplify the build system for +the FreedomBox +project. 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.

+ +

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 +Debian +Jessie based mesh node images for the Raspberry Pi. First, the +--foreign /path/to/binfm_handler 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 --bootsize size and --boottype +fstype 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 --variant +variant option to allow me to create smaller images without the +Debian base system packages installed. Finally, I added an option +--no-extlinux 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 +the +upstream project page.

+ +

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:

+ +

+#!/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
+

+ +

Next, fetch the latest vmdebootstrap script and call it like this +to build the image:

+ +

+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
+

+ +

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.

+ +

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.

+ +

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 Raspbian based images.

Narvik sparer minst 9 millioner pÃ¥ Ã¥ bruke Skolelinux

10th May 2013

I fjor sommer ble jeg -gledelig -overrasket over et oppslag i avisen Fremover om Narvik kommunes -bruk av Skolelinux. Oppslaget -var basert pÃ¥ et notat som besvarte spÃ¸rsmÃ¥l fra ordfÃ¸rer Tor NysÃ¦ter -og rÃ¥dgiver for skolesektoren, Petter Falkbu, om bruken av Skolelinux -i Narvikskolene og konstnaden ved Ã¥ gÃ¥ over til Windows. For litt -over en uke siden siden fikk jeg endelig bedt kommunen om Ã¥ fÃ¥ innsyn -i dette notatet, og det ble oversendt pÃ¥ epost tirsdag. Jeg fikk -lagt -ut notatet samme dag, og fikk i dag sjekket postlista til Narvik, -der jeg fant notatet som -sak -2013/1023.

- -

Notatet forteller at Narvik ville mÃ¥tte betalt minst 9 millioner -for Ã¥ gÃ¥ over til Windows pÃ¥ skolene. I tillegg dokumenterer notatet -at lÃ¦replanens krav oppfylles uten problemer ved bruk av Skolelinux. -Jeg anbefaler alle Ã¥ lese de 10 sidene med gode argumenter for Ã¥ kutte -unÃ¸dige utgifter pÃ¥ IT i skoleverket. :)

Det er jo makta som er mest sÃ¥rbar ved massiv overvÃ¥kning av Internett

26th October 2013

De siste mÃ¥neders eksponering av +den +totale overvÃ¥kningen som foregÃ¥r i den vestlige verden dokumenterer +hvor sÃ¥rbare vi er. Men det slÃ¥r meg at de som er mest sÃ¥rbare +for dette, myndighetspersoner pÃ¥ alle nivÃ¥er, neppe har innsett at de +selv er de mest interessante personene Ã¥ lage profiler pÃ¥, for Ã¥ kunne +pÃ¥virke dem.

+ +

For Ã¥ ta et lite eksempel: Stortingets nettsted, +www.stortinget.no (og +forsÃ¥vidt ogsÃ¥ +data.stortinget.no), +inneholder informasjon om det som foregÃ¥r pÃ¥ Stortinget, og jeg antar +de stÃ¸rste brukerne av informasjonen der er representanter og +rÃ¥dgivere pÃ¥ Stortinget. Intet overraskende med det. Det som derimot +er mer skjult er at Stortingets nettsted bruker +Google +Analytics, hvilket gjÃ¸r at enhver som besÃ¸ker nettsidene der ogsÃ¥ +rapporterer om besÃ¸ket via Internett-linjer som passerer Sverige, +England og videre til USA. Det betyr at informasjon om ethvert besÃ¸k +pÃ¥ stortingets nettsider kan snappes opp av svensk, britisk og USAs +etterretningsvesen. De kan dermed holde et Ã¸ye med hvilke +Stortingssaker stortingsrepresentantene synes er interessante Ã¥ sjekke +ut, og hvilke sider rÃ¥dgivere og andre pÃ¥ stortinget synes er +interessant Ã¥ besÃ¸ke, nÃ¥r de gjÃ¸r det og hvilke andre representanter +som sjekker de samme sidene omtrent samtidig. Stortingets bruk av +Google Analytics gjÃ¸r det dermed enkelt for utenlands etteretning Ã¥ +spore representantenes aktivitet og interesse. Hvis noen av +representantene bruker Google Mail eller noen andre tjenestene som +krever innlogging, sÃ¥ vil det vÃ¦re enda enklere Ã¥ finne ut nÃ¸yaktig +hvilke personer som bruker hvilke nettlesere og dermed knytte +informasjonen opp til enkeltpersoner pÃ¥ Stortinget.

+ +

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 Ã¥ undres +over.

Debian Wheezy is out - and Debian Edu / Skolelinux should soon follow! #newinwheezy

5th May 2013

When I woke up this morning, I was very happy to see that the -release announcement -for Debian Wheezy was waiting in my mail box. This is a great -Debian release, and I expect to move my machines at home over to it fairly -soon.

- -

The new debian release contain heaps of new stuff, and one program -in particular make me very happy to see included. The -Scratch program, made famous by -the Teach kids code movement, is -included for the first time. Alongside similar programs like -kturtle and -turtleart, -it allow for visual programming where syntax errors can not happen, -and a friendly programming environment for learning to control the -computer. Scratch will also be included in the next release of Debian -Edu. - -

And now that Wheezy is wrapped up, we can wrap up the next Debian -Edu/Skolelinux release too. The -first -alpha release went out last week, and the next should soon -follow.

A Raspberry Pi based batman-adv Mesh network node

21st October 2013

The last few days I have been experimenting with +the +batman-adv mesh technology. I want to gain some experience to see +if it will fit the +Freedombox project, 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.

+ +

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 +Raspberry Pi, 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 the Serval +Project 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.

+ +

To get this working, I've created a debian package +meshfx-node +and a script +build-rpi-mesh-node +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.

+ +

To create an image, run the following with a sudo enabled user +after inserting the target SD card into the build machine:

+ +

+% 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
+%
+

+ +

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 +an +earlier blog post about this mesh testing.

+ +

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:

+ +

+ + + + + + + + +
Supplier Model NOK
Teknikkmagasinet Raspberry Pi model B 349.90
Teknikkmagasinet Raspberry Pi type B case 99.90
Lefdal Jensen Air:Link 25150 295.-
Clas Ohlson Kingston 16 GB SD card 199.-

+ +

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. :)

For noen uker siden, innen fristen 2013-04-15, leverte jeg og -Morten Kjelkenes vÃ¥rt bidrag til -DIFIs apps4norge-konkurranse -under lagnavnet NUUGs tannlegeteam. -Vi leverte fÃ¸lgende i idÃ©-kategorien:

- -

- -
Tittel: Stikk innom tannlegen
- -
- -
Beskrivelse:
- -
IdÃ©en - -
GjÃ¸re det enklere Ã¥ finne en tannlege som er praktisk for deg, der -pris og reisetid med kollektivt, til fots eller med bil er tatt med i -beregningen, ved Ã¥ oppgi hvor en bor og jobber, og fÃ¥ forslag til -tannleger bÃ¥de i nÃ¦rheten og pÃ¥ veien mellom disse stedene.
- -
Brukeren oppgir hjemmeadresse og jobbadresse, og kanskje ogsÃ¥ -barnehage. SÃ¥ kan en ogsÃ¥ oppgi egen timelÃ¸nn (for Ã¥ beregne taps -arbeidsfortjeneste) og om en reiser med kollektivt, til fots eller -kjÃ¸rer bil. SÃ¥ trykker en sÃ¸k, og fÃ¥r opp en todelt side med kart og -tekstliste. I kartdelen vises aktuelle tannleger (for eksempel maks -7), og i tekstdelen er de samme tannlegene listet opp, med pris og -reisetid for kollektivtransport, og pris pluss reisekostnad hvis en -reiser med bil. En kan endre sorteringsrekkefÃ¸lge for listen ved Ã¥ -trykke pÃ¥ aktuell kolonne, og velge om en skal sortere pÃ¥ pris, -reisetid eller totalkostnad. Kun tannleger som tar imot nye kunder tas -i utganspunktet med i listen. NÃ¥r brukeren trykker med musa en -tannlegemarkÃ¸r pÃ¥ kartet kommer det en popup med detaljer om -tannlegen, den samme informasjonen som finnes i listen under kartet, -og lenke til mer informasjon om tannlegen.
- -
For hvert enkelt tannlegekontor er det tilgjengelig en -informasjonsside med adresse, hjemmesideurl, telefonnummer, lenke til -side for Ã¥ finne reisebeskrivelse, Ã¥pningstider, etc.
- -
Nytteverdi for brukeren
- -
-
sparer tid pÃ¥ tannlegebesÃ¸k
-
kan utnytte normal reisevei mellom hjem/jobb/barnehage
-
kan finne aktuell tannlege basert pÃ¥ flere kriterier
-
sile bort tannleger som ikke tar imot flere kunder
-
fÃ¥r kart som viser tannleger i nÃ¦rheten, pÃ¥ tvers av kommunegrenser
-
- -
Grad av innovasjon, nytenkning og kreativitet
- -
Enkel tjeneste som fokuserer pÃ¥ det vi selv mener er relevant ved valg -av tannlege.
- -
Tjenestekonseptet kan ogsÃ¥ brukes til andre nÃ¦ringer, f.eks. lege, -butikk, leiebiler, hvis en har aktuell datakilde Ã¥ koble med.
- -
Skulle gjerne hatt med vurdering av tannlegene tilgjengelig, slik -at en kunne finne "flinke" tannleger basert pÃ¥ et eller annet -kriterium.
- -
Markedspotensiale - potensiale for Ã¥ slÃ¥ gjennom hos mange -brukere
- -
-
Alle som Ã¸nsker eller vurderer Ã¥ skaffe seg ny tannlege, f.eks. nyinnflyttede og studenter
-
Familier med en travel hverdag
-
- -
Felles er at den gjÃ¸r tannlegen lettere tilgjengelig for de som vil spare tid eller penger.
- -
SamfunnsÃ¸konomisk nytte - bidrar til Ã¥ lÃ¸se -samfunnsutfordringer
- -
Kutter tid brukt pÃ¥ tannlegebesÃ¸k, og penger frigjÃ¸res som kan brukes pÃ¥ andre omrÃ¥der. Oppfordrer til bedre bruk av kollektivtransport ved Ã¥ gi tips om tannleger i nÃ¦rheten av allerede brukt reisevei mellom hjemme og jobb nÃ¥r en reiser kollektivt.
- -
X-faktor - âDet lille ekstra...â
- -
Denne tjenesten gir det lille ekstra ved at den ikke slÃ¥r opp -avstand til tannlege fra et enkelt punkt men avstand fra en reisevei, -slik at en fÃ¥r flere tannleger Ã¥ velge imellom og kanskje kan spare -enda mer tid og penger enn en ville gjort ved Ã¥ sjekke kun de nÃ¦rmest -hjemme eller jobb.
- -
Tjenesten gir informasjonen bÃ¥de som kart og som tekstlig oversikt, for Ã¥ sikre at blinde og svaksynte kan fÃ¥ tilgang til informasjonen selv om de ikke fÃ¥r brukt kartvisningen.

Good causes: Debian Outreach Program for Women, EFF documenting the spying and Open access in Norway

15th October 2013

The last few days I came across a few good causes that should get +wider attention. I recommend signing and donating to each one of +these. :)

+ +

Via Debian +Project News for 2013-10-14 I came across the Outreach Program for +Women program which is a Google Summer of Code like initiative to get +more women involved in free software. One debian sponsor has offered +to match any donation done to Debian +earmarked for this initiative. I donated a few minutes ago, and +hope you will to. :)

+ +

And the Electronic Frontier Foundation just announced plans to +create video +documentaries about the excessive spying on every Internet user that +take place these days, and their need to fund the work. I've already +donated. Are you next?

+ +

For my Norwegian audience, the organisation Studentenes og +Akademikernes Internasjonale Hjelpefond is collecting signatures for a +statement under the heading +Bloggers United for Open +Access for those of us asking for more focus on open access in the +Norwegian government. So far 499 signatures. I hope you will sign it +too.

Oslo community mesh network - with NUUG and Hackeriet at Hausmania

11th October 2013

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 +Freifunk and +Athens Wireless Metropolitan Network +(see +wikipedia +for a large list) 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 +dynamically +updated node graph and map, 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.

+ +

I've wanted to check out mesh networks for a while now, and hoped +to do it as part of my involvement with the NUUG member organisation community, and +my recent involvement in +the Freedombox project +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.

+ +

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 +Hackeriet at Husmania. They seem to +have started with some Freifunk based effort using OLSR, called +the Oslo +Freifunk project, but that effort is now dead and the people +behind it have moved on to a batman-adv based system called +meshfx. 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 JÃ¸rgen Lysglimt interview the +speakers about this talk (from +youtube):

+ +

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 +Serval project in Australia +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 +youtube):

+ +

According to the wikipedia page on +Wireless +mesh network 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.

+ +

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 +good +introduction is available from the Open Mesh project. These are +the key settings needed to join the Oslo meshfx network:

How to report bugs

- -

http://wiki.debian.org/DebianEdu/HowTo/ReportBugs

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 +"Information +about cell-id splitting, stuck beacons, and failed IBSS merges! +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. :)

+ +

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.

+ +

If you find this project interesting and want to join, please join +us on IRC, either channel +#oslohackerspace +or #nuug on +irc.freenode.net.

+ +

While investigating mesh networks in Oslo, I came across an old +research paper from the university of Stavanger and Telenor Research +and Innovation called +The +reliability of wireless backhaul mesh networks and elsewhere +learned that Telenor have been experimenting with mesh networks at +GrÃ¼nerlÃ¸kka 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?

+ +

Update 2013-10-12: I was just +told +by the Serval project developers that they no longer use +batman-adv (but are compatible with it), but their own crypto based +mesh system.

Bitcoin er ikke anonymt - fÃ¸res Stortinget bak lyset av finansministeren?

22nd April 2013

Bitcoin er mye i mediene for -tiden. Jeg fÃ¸lger med via Mylder for Ã¥ finne -artikler som omtaler -temaet, og takket vÃ¦re dette oppdaget jeg at stortingsrepresentant -Ketil Solvik-Olsen fra FrP nylig har spurt finansminister SigbjÃ¸rn -Johnsen om hans syn pÃ¥ Bitcoin, og -fÃ¥tt -svar for noen dager siden. Jeg bet meg spesielt merke til -fÃ¸lgende formulering fra finansministeren:

- -

-Â«Det er ogsÃ¥ utfordringer ved at handel med Bitcoins er uregulert og -at transaksjonene er anonyme.Â» -

- -

At Bitcoin er anonymt er en myte som spres av bÃ¥de journalister og -andre, sÃ¥ det er ikke veldig overraskende at ogsÃ¥ finansministeren har -gÃ¥tt pÃ¥ limpinnen. Det er dog litt rart, da jeg hÃ¥per at -finansdepartementet ikke baserer seg pÃ¥ rykter og myter nÃ¥r de -besvarer Stortinget. Men du trenger ikke bare tro pÃ¥ meg som kilde -til pÃ¥standen om at Bitcoin ikke er anonymt. Sondre RÃ¸njom har -via Sikkerhetsbloggen -hos Nasjonal Sikkerhetsmyndighet uttalt fÃ¸lgende:

- -

-Â«At [bitcoin] i utgangspunktet -ikke er anonymt, -kommer kanskje som en overraskelse pÃ¥ mange.Â» -

- -

Enhver bevegelse av Bitcoin er offentlig tilgjengelig for alle pÃ¥ -Internet, og en mÃ¥ legge svÃ¦rt mye innsats inn hvis en skal hindre at -nettverksanalyse av transaksjonsloggene kan brukes til Ã¥ identifisere -brukerne. F.eks. kan en enkelt se hva jeg har mottatt til min -offentliggjorte mottaksadresse ved Ã¥ besÃ¸ke blockexplorer og slÃ¥ opp -adressen -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b. -Det virker dermed pÃ¥ meg ganske klart at Ã¥ pÃ¥stÃ¥ at -Bitcoin-transaksjoner er anonyme strengt tatt er Ã¥ fÃ¸re Stortinget bak -lyset.

- -

Finansministeren er ikke den eneste som har latt seg forlede av -medieomtalen. I spÃ¸rsmÃ¥let fra Hr. Solvik-Olsen skriver han at Â«For -noen dager siden kom den fÃ¸rste bitcoin-minibanken pÃ¥ KyprosÂ», hvilket -sÃ¥ vidt jeg har klart Ã¥ finne ut ikke er riktig. Det er annonsert -planer om en slik minibank (fra -BitcoinATM), men jeg finner -intet tegn til at en slik minibank er utplassert noe sted.

- -

Som vanlig, hvis du bruker Bitcoin og Ã¸nsker Ã¥ vise din stÃ¸tte til -mine aktiviteter, sÃ¥ setter jeg pris pÃ¥ Bitcoin-donasjoner til min -adresse -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.

Skolelinux / Debian Edu 7.1 install and overview video from Marcelo Salvador

8th October 2013

The other day I was pleased and surprised to discover that Marcelo +Salvador had published a +video on +Youtube 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 Zygote Body 3D model +of the human body, 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 +LTSP server.

+ +

Anyway, check out the video, embedded below and linked to above:

Are there other nice videos demonstrating Skolelinux? Please let +me know. :)

See you on IRC, #debian-edu on irc.debian.org, then?

Finally, Debian Edu Wheezy is released today!

29th September 2013

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 +the Debian News +section, translated to several languages. Please check it out.

Mer innsyn i bakgrunnen for fjerning av ODF fra statens standardkatalog

9th April 2013

For cirka en mÃ¥ned siden -ba -jeg om begrunnelse pÃ¥ nektet innsyn i dokumenter om -standardkatalogen fra Fornyingsdepartementet. I dag fikk jeg svar fra -Fornyingsdepartementet, og tilgang til dokumentene. Jeg fikk bÃ¥de -innsyn i vedlegg sendt fra DIFI, og ogsÃ¥ innsyn i et notat brukt -internt i Fornyingsdepartementet:

Videos about the Freedombox project - for inspiration and learning

27th September 2013

The Freedombox +project have been going on for a while, and have presented the +vision, ideas and solution several places. Here is a little +collection of videos of talks and presentation of the project.

Fosdem 2011 +Keynote by Eben Moglen presenting the Freedombox (Youtube)

Det bÃ¸r nevnes at da jeg ble nektet innsyn hos mottaker -Fornyingsdepartementet pÃ¥ hÃ¸ringsoppsummeringen som DIFI hadde sendt -ut, spurte jeg DIFI om innsyn i stedet. Det fikk jeg i lÃ¸pet av et -par dager. Moralen er at hvis ikke mottaker ikke vil gi innsyn, spÃ¸r -avsender i stedet. Kanskje de har forskjellig forstÃ¥else av hva som -bÃ¸r holdes skjult for folket. Her er de tilsvarende dokumentene jeg -fikk innsyn i fra DIFI:

Presentation of +the Freedombox by James Vasile at Elevate in Gratz 2011 (Youtube)

Det jeg synes er mest interessant er endel av aktÃ¸rene som -protesterte pÃ¥ fjerningen (Kartverket, Drammen kommune), og hvordan -hÃ¸ringsoppsummeringen ikke tar stilling til effekten av Ã¥ fjerne ODF -fra katalogen.

A larger list is available from +the +Freedombox Wiki.

+ +

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.

Sandy Island - Ã¸ya som er synlig hver tirsdag og fredag?

7th April 2013

For en stund tilbake gikk nyheten om -Sandy -Island, en Ã¸y som var dukket opp pÃ¥ noen kart, men som ikke var -synlig nÃ¥r en sjekket den pÃ¥ satellittbilder. Dagbladet meldte for -eksempel at -Â«denne -Ã¸ya finnes pÃ¥ kart, men ikke i virkelighetenÂ». Noe senere begynte -jeg Ã¥ lese -historier -om Ruffen til mine barn. Dette er historier om sjÃ¸ormen Ruffen -skapt av Tor Ãge BringsvÃ¦rd, som starter med fÃ¸lgende beskrivelse:

- -

-Â«Langt ute i havet ligger en mystisk Ã¸y. Den er bare synlig hver -tirsdag og fredag. Derfor stÃ¥r den ikke pÃ¥ noe kart. PÃ¥ denne Ã¸ya -ligger et slott, og i slottet bor en gammel, fin sjÃ¸ormfamilie.Â» -

- -

Det virker Ã¥penbart at Hr. BringsvÃ¦rd tok feil nÃ¥r han trodde den -ikke var pÃ¥ noe kart, og at noen tydeligvis har vÃ¦rt i nÃ¦rheten en -tirsdag eller en fredag og fÃ¥tt den med pÃ¥ et kart, mens -satellittbildene er tatt pÃ¥ noen av de fem andre dagene i uka og -dermed ikke ser Ã¸ya. :)

- -

I fÃ¸lge -en -senere artikkel i Dagbladet hevder Shaun Higgins, en forsker fra -New Zealand, at et hvalfangstskip fra 1876 er opprinnelsen til at -spÃ¸kelsesÃ¸ya i det hele tatt havnet pÃ¥ kartet. Det fremgÃ¥r ikke fra -historien hvilken ukedag de var innom.

Jeg har stor sans for Tor Ãge BringsvÃ¦rd. Og han viste nylig en -svÃ¦rt fin side av seg selv da han sa ja til EFNs forespÃ¸rsel om Ã¥ gi -ut novellen KodÃ©mus med -Creative Commons-lisens.
