Dugnadsnett for alle stiller på Oslo Maker Faire i januar 2014
-
10th December 2013

Helga 18. og 19. januar 2014 arrangeres -Oslo Maker -Faire, og Dugnadsnett for -alle har fått plass! Planen er å ha et bord med en plakat der vi -forteller om hva Dugnadsnett for alle er for noe, og et lite verksted -der vi hjelper folk som er interessert i å få opp sin egen mesh-node. -Jeg gleder meg til å se hvordan prosjektet blir mottatt der.

The Freedombox +project is working on providing the software and hardware for +making it easy for non-technical people to host their data and +communication at home, and being able to communicate with their +friends and family encrypted and away from prying eyes. It has been +going on for a while, and is slowly progressing towards a new test +release (0.2).

+ +

And what day could be better than the Pi day to announce that the +new version will provide "hard drive" / SD card / USB stick images for +Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization +system), and can also be installed using a Debian installer preseed +file. The Debian based Freedombox is now based on Debian Jessie, +where most of the needed packages used are already present. Only one, +the freedombox-setup package, is missing. To try to build your own +boot image to test the current status, fetch the freedom-maker scripts +and build using +vmdebootstrap +with a user with sudo access to become root: -

Målet med dugnadsnett for alle i Oslo er å få på plass et datanett -for kommunikasjon ved hjelp av radio-repeaterstasjoner (kalt -mesh-noder) som gjør at en kan direkte kommunisere med slekt, venner -og bekjente i Oslo via andre som deltar i dugnadsnettet, samt gjøre -det mulig komme ut på internett via dugnadsnettet. Første delmål er å -kunne sende SMS-meldinger vha. IP-telefoni løsningen -Serval project mellom -deltagerne i Dugnadsnett for alle i Oslo. Formålet er å ta tilbake -kontrollen over egen nett-infrastruktur og gjøre det dyrere å bedrive -massiv innsamling av informasjon om borgernes bruk av datanett.

+  mktorrent extlinux virtualbox qemu-user-static binfmt-support \
+  u-boot-tools
+make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
+
-

Høres dette interessant ut? Bli med på prosjektet, fortell oss -hvor du kunne tenke deg å sette opp en radio-repeater (slik at folk i -nærheten kan finne hverandre ved hjelp av -kartet over planlagte og -eksisterende radio-repeatere), bli med på epostlisten -dugnadsnett -(at) nuug.no og stikk innom -IRC-kanalen -#dugnadsnett.no. Så langt er det planlagt over 40 -radio-repeatere, med VPN-forbindelser via Internet for å la de delene -av nettet som ikke når hverandre via radio kunne snakke med hverandre -likevel.

+

Root access is needed to run debootstrap and mount loopback +devices. See the README for more details on the build. If you do not +want all three images, trim the make line. But note that thanks to a race condition in +vmdebootstrap, the build might fail without the patch to the +kpartx call.

+ +

If you instead want to install using a Debian CD and the preseed +method, boot a Debian Wheezy ISO and use this boot argument to load +the preseed values:

+ +
+url=http://www.reinholdtsen.name/freedombox/preseed-jessie.dat
+
+ +

But note that due to a +recently introduced bug in apt in Jessie, the installer will +currently hang while setting up APT sources. Killing the +'apt-cdrom ident' process when it hang a few times during the +installation will get the installation going. This affect all +installations in Jessie, and I expect it will be fixed soon.

+ +Give it a go and let us know how it goes on the mailing list, and help +us get the new release published. :) Please join us on +IRC (#freedombox on +irc.debian.org) and +the +mailing list if you want to help make this vision come true.

It has been a while since I managed to publish the last interview, -but the Debian Edu / -Skolelinux community is still going strong, and yesterday we even -had a new school administrator show up on -#debian-edu to share -his success story with installing Debian Edu at their school. This -time I have been able to get some helpful comments from the creator of -Knoppix, Klaus Knopper, who was involved in a Skolelinux project in -Germany a few years ago.

- -

Who are you, and how do you spend your days?

- -

I am Klaus Knopper. I have a master degree in electrical -engineering, and is currently professor in information management at -the university of applied sciences Kaiserslautern / Germany and -freelance Open Source software developer and consultant.

- -

All of this is pretty much of the work I spend my days with. Apart -from teaching, I'm also conducting some more or less experimental -projects like the Knoppix GNU/Linux live -system (Debian-based like Skolelinux), -ADRIANE -(a blind-friendly talking desktop system) and -LINBO -(Linux-based network boot console, a fast remote install and repair -system supporting various operating systems).

- -

How did you get in contact with the Skolelinux / Debian Edu -project?

- -

The credit for this have to go to Kurt Gramlich, who is the German -coordinator for Skolelinux. We were looking for an all-in-one open -source community-supported distribution for schools, and Kurt -introduced us to Skolelinux for this purpose.

- -

What do you see as the advantages of Skolelinux / Debian -Edu?

- -
    -
  • Quick installation,
  • -
  • works (almost) out of the box,
  • -
  • contains many useful software packages for teaching and learning,
  • -
  • is a purely community-based distro and not controlled by a - single company,
  • -
  • has a large number of supporters and teachers who share their - experience and problem solutions.
  • -
- -

What do you see as the disadvantages of Skolelinux / Debian -Edu?

- -
    -
  • Skolelinux is - as we had to learn - not easily upgradable to - the next version. Opposed to its genuine Debian base, upgrading to - a new version means a full new installation from scratch to get it - working again reliably. - -
  • Skolelinux is based on Debian/stable, and therefore always a - little outdated in terms of program versions compared to Edubuntu or - similar educational Linux distros, which rather use Debian/testing - as their base. - -
  • Skolelinux has some very self-opinionated and stubborn default - configuration which in my opinion adds unnecessary complexity and is - not always suitable for a schools needs, the preset network - configuration is actually a core definition feature of Skolelinux - and not easy to change, so schools sometimes have to change their - network configuration to make it "Skolelinux-compatible". - -
  • Some proposed extensions, which were made available as - contribution, like secure examination mode and lecture material - distribution and collection, were not accepted into the mainline - Skolelinux development and are now not easy to maintain in the - future because of Skolelinux somewhat undeterministic update - schemes.
  • - -
  • Skolelinux has only a very tiny number of base developers - compared to Debian.
  • - -
- -

For these reasons and experience from our project, I would now -rather consider using plain Debian for schools next time, until -Skolelinux is more closely integrated into Debian and becomes -upgradeable without reinstallation.

- -

Which free software do you use daily?

- -

GNU/Linux with LXDE desktop, bash for interactive dialog and -programming, texlive for documentation and correspondence, -occasionally LibreOffice for document format conversion. Various -programming languages for teaching.

- -

Which strategy do you believe is the right one to use to -get schools to use free software?

- -

Strong arguments are

- -
    - -
  • Knowledge is free, and so should be methods and tools for - teaching and learning.
  • - -
  • Students can learn with and use the same software at school, at - home, and at their working place without running into license or - conversion problems.
  • - -
  • Closed source or proprietary software hides knowledge rather - than exposing it, and proprietary software vendors try to bind - customers to certain products. But teachers need to teach - science, not products.
  • - -
  • If you have everything you for daily work as open source, what - would you need proprietary software for?

On larger sites, it is useful to use a dedicated storage server for +storing user home directories and data. The design for handling this +in Debian Edu / Skolelinux, is +to update the automount rules in LDAP and let the automount daemon on +the clients take care of the rest. I was reminded about the need to +document this better when one of the customers of +Skolelinux Drift AS, where I am +on the board of directors, asked about how to do this. The steps to +get this working are the following:

+ +

    + +
  1. Add new storage server in DNS. I use nas-server.intern as the +example host here.
  2. + +
  3. Add automoun LDAP information about this server in LDAP, to allow +all clients to automatically mount it on reqeust.
  4. + +
  5. Add the relevant entries in tjener.intern:/etc/fstab, because +tjener.intern do not use automount to avoid mounting loops.
  6. + +

+ +

DNS entries are added in GOsa², and not described here. Follow the +instructions +in the manual (Machine Management with GOsa² in section Getting +started).

+ +

Ensure that the NFS export points on the server are exported to the +relevant subnets or machines:

+ +

+root@tjener:~# showmount -e nas-server
+Export list for nas-server:
+/storage         10.0.0.0/8
+root@tjener:~#
+

+ +

Here everything on the backbone network is granted access to the +/storage export. With NFSv3 it is slightly better to limit it to +netgroup membership or single IP addresses to have some limits on the +NFS access.

+ +

The next step is to update LDAP. This can not be done using GOsa², +because it lack a module for automount. Instead, use ldapvi and add +the required LDAP objects using an editor.

+ +

+ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
+

+ +

When the editor show up, add the following LDAP objects at the +bottom of the document. The "/&" part in the last LDAP object is a +wild card matching everything the nas-server exports, removing the +need to list individual mount points in LDAP.

+ +

+add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: automount
+cn: nas-server
+automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+
+add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: top
+objectClass: automountMap
+ou: auto.nas-server
+
+add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: automount
+cn: /
+automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
+

+ +

The last step to remember is to mount the relevant mount points in +tjener.intern by adding them to /etc/fstab, creating the mount +directories using mkdir and running "mount -a" to mount them.

+ +

When this is done, your users should be able to access the files on +the storage server directly by just visiting the +/tjener/nas-server/storage/ directory using any application on any +workstation, LTSP client or LTSP server.

For noen uker siden ble NXCs fri programvarelisenserte +NOARK5-løsning +presentert hos +NUUG (video +på youtube +foreløbig), og det fikk meg til å titte litt mer på NOARK5, +standarden for arkivhåndtering i det offentlige Norge. Jeg lurer på +om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett +av dem er det mest aktuelt å lagre epost. Jeg klarte ikke finne noen +anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost) +burde lagres i NOARK5, selv om jeg vet at noen arkiver tar +PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en +(eller enda værre, tar papirutskrift og lagrer bildet av eposten som +PDF i arkivet).

+ +

Det er ikke så mange formater som er akseptert av riksarkivet til +langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest +aktuelle i så måte. Det slo meg at det måtte da finnes en eller annen +egnet XML-representasjon og at det kanskje var enighet om hvilken som +burde brukes, så jeg tok mot til meg og spurte +SAMDOK, en gruppe tilknyttet +arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde +noen anbefalinger: + +

+

Hei.

+ +

Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg +lurer på om det er definert en anbefaling om hvordan RFC +822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres +i NOARK5, slik at en bevarer all informasjon i eposten +(f.eks. Received-linjer). Finnes det en anbefalt XML-mapping ala den +som beskrives på +<URL: https://www.informit.com/articles/article.aspx?p=32074 >? Mitt +mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og +kunne få ut en identisk formattert kopi av opprinnelig epost ved +behov.

+

+ +

Postmottaker hos SAMDOK mente spørsmålet heller burde stilles +direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av +seniorrådgiver Geir Ivar Tungesvik:

+ +

+

Riksarkivet har ingen anbefalinger når det gjelder konvertering fra +e-post til XML. Det står arkivskaper fritt å eventuelt definere/bruke +eget format. Inklusive da - som det spørres om - et format der det er +mulig å re-etablere e-post format ut fra XML-en. XML (e-post) +dokumenter må være referert i arkivstrukturen, og det må vedlegges et +gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt +til å gjøre hva de vil, bare det dokumenteres og det kan dannes et +utrekk ved avlevering til depot.

+ +

De obligatoriske kravene i Noark 5 standarden må altså oppfylles - +etter dialog med Riksarkivet i forbindelse med godkjenning. For +offentlige arkiv er det særlig viktig med filene loependeJournal.xml +og offentligJournal.xml. Private arkiv som vil forholde seg til Noark +5 standarden er selvsagt frie til å bruke det som er relevant for dem +av obligatoriske krav.

+

+ +

Det ser dermed ut for meg som om det er et lite behov for å +standardisere XML-lagring av RFC-822-formatterte meldinger. Noen som +vet om god spesifikasjon i så måte? I tillegg til den omtalt over, +har jeg kommet over flere aktuelle beskrivelser (søk på "rfc 822 +xml", så finner du aktuelle alternativer).

+ + + +

Finnes det andre og bedre spesifikasjoner for slik lagring? Send +meg en epost hvis du har innspill.

I placed the project under the +Hungry Programmer umbrella, and it was maintained in our CVS +repository. But many years ago, the CVS repository was dropped (lost, +not migrated to new hardware, not sure), and the project have lacked a +proper home since then.

    I fjor sommer lagde jeg en -offentlig -tilgjengelig SQL-database over offentlig anbud 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.

    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.

    -   where abstract like '%linux%' or title like '%linux%'
    -   order by seq desc limit 20
    -

    - -

    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.

    Du lurer kanskje på hva slags informasjon en kan få ut fra denne -databasen. Her er to RSS-kilder, med søkeordet -"linux", -søkeordet -"fri -programvare" -og søkeordet -"odf". -Det er bare å søke på det en er interessert i. Kopier gjerne -datasettet og sett opp din egen tjeneste hvis du vil gjøre mer -avanserte søk. SQLite-filen med Doffin-oppføringer kan lastes med fra -Scraperwiki for de som vil grave dypere.

    A few days ago I decided to try to help the Hurd people to get +their changes into sysvinit, to allow them to use the normal sysvinit +boot system instead of their old one. This follow up on the +great +Google Summer of Code work done last summer by Justus Winter to +get Debian on Hurd working more like Debian on Linux. To get started, +I downloaded a prebuilt hard disk image from +http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz, +and started it using virt-manager.

    + +

    The first think I had to do after logging in (root without any +password) was to get the network operational. I followed +the +instructions on the Debian GNU/Hurd ports page and ran these +commands as root to get the machine to accept a IP address from the +kvm internal DHCP server:

    + +

    +settrans -fgap /dev/netdde /hurd/netdde
    +kill $(ps -ef|awk '/[p]finet/ { print $2}')
    +kill $(ps -ef|awk '/[d]evnode/ { print $2}')
    +dhclient /dev/eth0
    +

    + +

    After this, the machine had internet connectivity, and I could +upgrade it and install the sysvinit packages from experimental and +enable it as the default boot system in Hurd.

    + +

    But before I did that, I set a password on the root user, as ssh is +running on the machine it for ssh login to work a password need to be +set. Also, note that a bug somewhere in openssh on Hurd block +compression from working. Remember to turn that off on the client +side.

    + +

    Run these commands as root to upgrade and test the new sysvinit +stuff:

    + +

    +cat > /etc/apt/sources.list.d/experimental.list <<EOF
    +deb http://http.debian.net/debian/ experimental main
    +EOF
    +apt-get update
    +apt-get dist-upgrade
    +apt-get install -t experimental initscripts sysv-rc sysvinit \
    +    sysvinit-core sysvinit-utils
    +update-alternatives --config runsystem
    +

    + +

    To reboot after switching boot system, you have to use +reboot-hurd instead of just reboot, as there is not +yet a sysvinit process able to receive the signals from the normal +'reboot' command. After switching to sysvinit as the boot system, +upgrading every package and rebooting, the network come up with DHCP +after boot as it should, and the settrans/pkill hack mentioned at the +start is no longer needed. But for some strange reason, there are no +longer any login prompt in the virtual console, so I logged in using +ssh instead. + +

    Note that there are some race conditions in Hurd making the boot +fail some times. No idea what the cause is, but hope the Hurd porters +figure it out. At least Justus said on IRC (#debian-hurd on +irc.debian.org) that they are aware of the problem. A way to reduce +the impact is to upgrade to the Hurd packages built by Justus by +adding this repository to the machine:

    + +

    +cat > /etc/apt/sources.list.d/hurd-ci.list <<EOF
    +deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
    +EOF
    +

    + +

    At the moment the prebuilt virtual machine get some packages from +http://ftp.debian-ports.org/debian, because some of the packages in +unstable do not yet include the required patches that are lingering in +BTS. This is the completely list of "unofficial" packages installed:

    + +

    +# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'

    Drones, flying robots, are getting more and more popular. The most -know ones are the killer drones used by some government to murder -people they do not like without giving them the chance of a fair -trial, but the technology have many good uses too, from mapping and -forest maintenance to photography and search and rescue. I am sure it -is just a question of time before "bad drones" are in the hands of -private enterprises and not only state criminals but petty criminals -too. The drone technology is very useful and very dangerous. To have -some control over the use of drones, I agree with Daniel Suarez in his -TED talk -"The kill -decision shouldn't belong to a robot", where he suggested this -little gem to keep the good while limiting the bad use of drones:

    - -
    - -

    Each robot and drone should have a cryptographically signed -I.D. burned in at the factory that can be used to track its movement -through public spaces. We have license plates on cars, tail numbers on -aircraft. This is no different. And every citizen should be able to -download an app that shows the population of drones and autonomous -vehicles moving through public spaces around them, both right now and -historically. And civic leaders should deploy sensors and civic drones -to detect rogue drones, and instead of sending killer drones of their -own up to shoot them down, they should notify humans to their -presence. And in certain very high-security areas, perhaps civic -drones would snare them and drag them off to a bomb disposal facility.

    - -

    But notice, this is more an immune system than a weapons system. It -would allow us to avail ourselves of the use of autonomous vehicles -and drones while still preserving our open, civil society.

    - -
    - -

    The key is that every citizen should be able to read the -radio beacons sent from the drones in the area, to be able to check -both the government and others use of drones. For such control to be -effective, everyone must be able to do it. What should such beacon -contain? At least formal owner, purpose, contact information and GPS -location. Probably also the origin and target position of the current -flight. And perhaps some registration number to be able to look up -the drone in a central database tracking their movement. Robots -should not have privacy. It is people who need privacy.

    Bitcoin is a incredible use of peer to peer communication and +encryption, allowing direct and immediate money transfer without any +central control. It is sometimes claimed to be ideal for illegal +activity, which I believe is quite a long way from the truth. At least +I would not conduct illegal money transfers using a system where the +details of every transaction are kept forever. This point is +investigated in +USENIX ;login: +from December 2013, in the article +"A +Fistful of Bitcoins - Characterizing Payments Among Men with No +Names" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill +Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage. They +analyse the transaction log in the Bitcoin system, using it to find +addresses belong to individuals and organisations and follow the flow +of money from both Bitcoin theft and trades on Silk Road to where the +money end up. This is how they wrap up their article:

    + +

    +

    "To demonstrate the usefulness of this type of analysis, we turned +our attention to criminal activity. In the Bitcoin economy, criminal +activity can appear in a number of forms, such as dealing drugs on +Silk Road or simply stealing someone else’s bitcoins. We followed the +flow of bitcoins out of Silk Road (in particular, from one notorious +address) and from a number of highly publicized thefts to see whether +we could track the bitcoins to known services. Although some of the +thieves attempted to use sophisticated mixing techniques (or possibly +mix services) to obscure the flow of bitcoins, for the most part +tracking the bitcoins was quite straightforward, and we ultimately saw +large quantities of bitcoins flow to a variety of exchanges directly +from the point of theft (or the withdrawal from Silk Road).

    + +

    As acknowledged above, following stolen bitcoins to the point at +which they are deposited into an exchange does not in itself identify +the thief; however, it does enable further de-anonymization in the +case in which certain agencies can determine (through, for example, +subpoena power) the real-world owner of the account into which the +stolen bitcoins were deposited. Because such exchanges seem to serve +as chokepoints into and out of the Bitcoin economy (i.e., there are +few alternative ways to cash out), we conclude that using Bitcoin for +money laundering or other illicit purposes does not (at least at +present) seem to be particularly attractive."

    +

    + +

    These researches are not the first to analyse the Bitcoin +transaction log. The 2011 paper +"An Analysis of Anonymity in +the Bitcoin System" by Fergal Reid and Martin Harrigan is +summarized like this:

    + +

    +"Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a +complicated issue. Within the system, users are identified by +public-keys only. An attacker wishing to de-anonymize its users will +attempt to construct the one-to-many mapping between users and +public-keys and associate information external to the system with the +users. Bitcoin tries to prevent this attack by storing the mapping of +a user to his or her public-keys on that user's node only and by +allowing each user to generate as many public-keys as required. In +this chapter we consider the topological structure of two networks +derived from Bitcoin's public transaction history. We show that the +two networks have a non-trivial topological structure, provide +complementary views of the Bitcoin system and have implications for +anonymity. We combine these structures with external information and +techniques such as context discovery and flow analysis to investigate +an alleged theft of Bitcoins, which, at the time of the theft, had a +market value of approximately half a million U.S. dollars." +

    + +

    I hope these references can help kill the urban myth that Bitcoin +is anonymous. It isn't really a good fit for illegal activites. Use +cash if you need to stay anonymous, at least until regular DNA +sampling of notes and coins become the norm. :)

    + +

    Coverity is a nice tool to +find problems in C, C++ and Java code using static source code +analysis. It can detect a lot of different problems, and is very +useful to find memory and locking bugs in the error handling part of +the source. The company behind it provide +check of free software projects as +a community service, and many hundred free software projects are +already checked. A few days ago I decided to have a closer look at +the Coverity system, and discovered that the +gnash and +ipmitool +projects I am involved with was already registered. But these are +fairly big, and I would also like to have a small and easy project to +check, and decided to request +checking of the chrpath project. It was +added to the checker and discovered seven potential defects. Six of +these were real, mostly resource "leak" when the program detected an +error. Nothing serious, as the resources would be released a fraction +of a second later when the program exited because of the error, but it +is nice to do it right in case the source of the program some time in +the future end up in a library. Having fixed all defects and added +a +mailing list for the chrpath developers, I decided it was time to +publish a new release. These are the release notes:

    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 -OpenWrt.

    - -

    I started by following the instructions on the OpenWRT wiki for -TL-MR3040, -and downloaded -the -recommended firmware image -(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.

    - -

    I started off by reading the instructions from -Wireless -Africa, which had quite a lot of useful information, but -eventually I followed the recipe from the Open Mesh wiki for -using -batman-adv on OpenWrt. A small snag was the fact that the -opkg install kmod-batman-adv 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 -reported the bug 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.

    - -

    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:

    I am a 23 year-old student from Germany who has spent half of his +life with open source. In "real life", I am, as already mentioned, a +student in the fields of Computer Science, Electrical Engineering, +Information Technologies and Anglistics. Due to my (only partially +voluntary) huge engagement in the open source world, these things are +a bit vacant right now however.

    + +

    I also have been working as a project teacher at a Gymasnium +(public school) for various years now. I took up that work some time +around 2005 when still attending that school myself and have continued +it until today. I also had been running the (kind of very advanced) +network of that school together with a team of very interested and +talented students in the age of 11 to 15 years, who took the chance to +learn a lot about open source and networking before I left the school +to help building another school's informational education concept from +scratch.

    + +

    That said, one might see me as a kind of "glue" between school kids +and the elderly of teachers as well as between the open source +ecosystem and the (even more complex) educational ecosystem.

    I think that happened some time around 2009 when I first attended +FrOSCon and visited the project +booth. I think I wasn't too interested back then because I used to +have an attitude of disliking software that does too much stuff on its +own. Maybe I was too inexperienced to realise the upsides of an +"out-of-the-box" solution ;).

    + +

    The first time I actively talked to Skolelinux people was at +OpenRheinRuhr 2011 when the +BiscuIT project, a home-grewn software used by my school for various +really cool things from timetables and class contact lists to lunch +ordering, student ID card printing and project elections first got to +a stage where it could have been published. I asked the Skolelinux +guys running the booth if the project were interested in it and gave a +small demonstration, but there wasn't any real feedback and the guys +seemed rather uninterested.

    + +

    After I left the school where I developed the software, it got +mostly lost, but I am now reimplementing it for my new school. I have +reusability and compatibility in mind, and I hop there will be a new +basis for contributing it to the Skolelinux project ;)!

    +

    What do you see as the advantages of Skolelinux / Debian +Edu?

    + +

    The most important advantage seems to be that it "just +works". After overcoming some minor (but still very annoying) glitches +in the installer, I got a fully functional, working school network, +without the month-long hassle I experienced when setting all that up +from scratch in earlier years. And above that, it rocked - I didn't +have any real hardware at hand, because the school was just founded +and has no money whatsoever, so I installed a combined server (main +server, terminal services and workstation) in a VM on my personal +notebook, bridging the LTSP network interface to the ethernet port, +and then PXE-booted the Windows notebooks that were lying around from +it. I could use 8 clients without any performance issues, by using a +tiny little VM on a tiny little notebook. I think that's enough to say +that it rocks!

    + +

    Secondly, there are marketing reasons. Life's bad, and so no +politician will ever permit a setup described as "Debian, an universal +operating system, with some really cool educational tools" while they +will be jsut fine with "Skolelinux, a single-purpose solution for your +school network", even if both turn out to be the very same thing (yes, +this is unfair towards the Skolelinux project, and must not be taken +too seriously - you get the idea, anyway).

    + +

    What do you see as the disadvantages of Skolelinux / Debian +Edu?

    + +

    I have not been involved with Skolelinux long enough to really +answer this question in a fair way. Thus, please allow me to put it in +other words: "What do you expect from Skolelinux to keep liking it?" I +can list a few points about that:

    + +
      + +
    • always strive to get all things integrated into Debian upstream +
    • be open to discussion about changes and the like, even with newcomers +
    • be helpful at being helpful ;) + +
    + +

    I'm really sorry I cannot say much more about that :(!

    + +

    Which free software do you use daily?

    + +

    First of all, all software I use is free and open. I have abandoned +all non-free software (except for firmware on my darned phone) this +year.

    + +

    I run Debian GNU/Linux on all PC systems I use. On that, I mostly +run text tools. I use +mksh as shell, +jupp as very advanced +text editor (I even got the developer to help me write a script/macro +based full-featured student management software with the two), +mcabber for XMPP and +irssi for IRC. For that overly +coloured world called the WWW, I use +Iceweasel +(Firefox). Oh, and mutt for +e-mail.

    + +

    However, while I am personally aware of the fact that text tools +are more efficient and powerful than anything else, I also use (or at +least operate) some tools that are suitable to bring open source to +kids. One of these things is Jappix, +which I already introduced to some kids even before they got aware of +Facebook, making them see for themselves that they do not need +Facebook now ;).

    + +

    Which strategy do you believe is the right one to use to +get schools to use free software?

    -

    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.

    +

    Well, that's a two-sided thing. One side is what I believe, and one +side is what I have experienced.

    + +

    I believe that the right strategy is showing them the benefits. But +that won't work out as long as the acceptance of free alternatives +grows globally. What I mean is that if all the kids are almost forced +to use Windows, Facebook, Skype, you name it at home, they will not +see why they would want to use alternatives at school. I have seen +students take seat in front of a fully-functional, modern Debian +desktop that could do anything their Windows at home could do, and +they jsut refused to use it because "Linux sucks". It is something +that makes the council of our city spend around 600000 € to buy +software - not including hardware, mind you - for operating school +networks, and for installing a system that, as has been proved, does +not work. For those of you readers who are good at maths, have you +already found out how many lives could have been saved with that money +if we had instead used it to bring education to parts of the world +that need it? I have, and found it to be nothing less dramatic than +plain criminal.

    + +

    That said, the only feasible way appears to be the bottom up +method. We have to bring free software to kids and parents. I have +founded an association named +Teckids here in Germany that does +just that. We organise several events for kids and adolescents in the +area of free and open source software, for example the +FrogLabs, which share staff with +Teckids and are the youth programme of +the Free and Open Source Software +Conference (FrOSCon). We do a lot more than most other conferences +- this year, we first offered the FrogLabs as a holiday camp for kids +aged 10 to 16. It was a huge success, with approx. 30 kids taking part +and learning with and about free software through a whole weekend. All +of us had a lot of fun, and the results were really exciting.

    + +

    Apart from that, we are preparing a campaign that is supposed to bring +the message of free alternatives to stuff kids use every day to them and +their parents, e.g. the use of Jabber / Jappix instead of Facebook and +Skype. To make that possible, we are planning to get together a team of +clever kids who understand very well what their peers need and can bring +it across to them. So we will have a peer-driven network of adolescents +who teach each other and collect feedback from the community of minors. +We then take that feedback and our own experience to work closely with +open source projects, such as Skolelinux or Jappix, at improving their +software in a way that makes it more and more attractive for the target +group. At least I hope that we will have good cooperation with +Skolelinux in the future ;)!

    + +

    So in conclusion, what I believe is that, if it weren't for the world +being so bad, it should be very clear to the political decision makers +that the only way to go nowadays is free software for various reasons, +but I have learnt that the only way that seems to work is bottom up.

    Helga 18. og 19. januar 2014 arrangeres +Oslo Maker +Faire, og Dugnadsnett for +alle har fått plass! Planen er å ha et bord med en plakat der vi +forteller om hva Dugnadsnett for alle er for noe, og et lite verksted +der vi hjelper folk som er interessert i å få opp sin egen mesh-node. +Jeg gleder meg til å se hvordan prosjektet blir mottatt der.

    Målet med dugnadsnett for alle i Oslo er å få på plass et datanett +for kommunikasjon ved hjelp av radio-repeaterstasjoner (kalt +mesh-noder) som gjør at en kan direkte kommunisere med slekt, venner +og bekjente i Oslo via andre som deltar i dugnadsnettet, samt gjøre +det mulig komme ut på internett via dugnadsnettet. Første delmål er å +kunne sende SMS-meldinger vha. IP-telefoni løsningen +Serval project mellom +deltagerne i Dugnadsnett for alle i Oslo. Formålet er å ta tilbake +kontrollen over egen nett-infrastruktur og gjøre det dyrere å bedrive +massiv innsamling av informasjon om borgernes bruk av datanett.

    It is based on /etc/init.d/skeleton, and could be improved quite a -lot. I did not really polish the approach, so it might not always -work out of the box, but you get the idea. I did not try very hard to -optimize it nor make it more robust either.

    A better argument for switching init system in Debian than reducing -the size of init scripts (which is a good thing to do anyway), is to -get boot system that is able to handle the kernel events sensibly and -robustly, and do not depend on the boot to run sequentially. The boot -and the kernel have not behaved sequentially in years.

Bli med på prosjektet, fortell oss +hvor du kunne tenke deg å sette opp en radio-repeater (slik at folk i +nærheten kan finne hverandre ved hjelp av +kartet over planlagte og +eksisterende radio-repeatere), bli med på epostlisten +dugnadsnett +(at) nuug.no og stikk innom +IRC-kanalen +#dugnadsnett.no. Så langt er det planlagt over 40 +radio-repeatere, med VPN-forbindelser via Internet for å la de delene +av nettet som ikke når hverandre via radio kunne snakke med hverandre +likevel.
