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 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.

- -

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.

+ +

This is the sixth test release based on Debian Wheezy. Basically this +is an updated and slightly improved version compared to the Squeeze +release.

+ +

ALERT: Alpha based installations should reinstall or downgrade the +versions of gosa and libpam-mklocaluser to the ones used in this beta +release. Both alpha and beta0 based installations should reinstall or +deal with gosa.conf manually; there are two options: (1) Keep +gosa.conf and edit this file as outlined +on +the mailing list. (2) Accept the new version of gosa.conf and +replace both contained admin password placeholders with the password +hashes found in the old one (backup copy!). In both cases every user +need to change their their password to make sure a password is set for +CIFS access to their home directory.

Software updates

+

Earlier, I reported about +my +problems using an Intel SSD 520 Series 180 GB disk. Friday I was +told by IBM that the original disk should be thrown away. And as +there no longer was a problem if I bricked the firmware, I decided +today to try to install Intel firmware to replace the Lenovo firmware +currently on the disk.

+ +

I searched the Intel site for firmware, and found +issdfut_2.0.4.iso +(aka Intel SATA Solid-State Drive Firmware Update Tool) which +according to the site should contain the latest firmware for SSD +disks. I inserted the broken disk in one of my spare laptops and +booted the ISO from a USB stick. The disk was recognized, but the +program claimed the newest firmware already were installed and refused +to insert any Intel firmware. So no change, and the disk is still +unable to handle write load. :( I guess the only way to get them +working would be if Lenovo releases new firmware. No idea how likely +that is. Anyway, just blogging about this test for completeness. I +got a working Samsung disk, and see no point in spending more time on +the broken disks.

I fjor sommer ble jeg -gledelig -overrasket over et oppslag i avisen Fremover om Narvik kommunes -bruk av Skolelinux. Oppslaget -var basert på et notat som besvarte spørsmål fra ordfører Tor Nysæter -og rådgiver for skolesektoren, Petter Falkbu, om bruken av Skolelinux -i Narvikskolene og konstnaden ved å gå over til Windows. For litt -over en uke siden siden fikk jeg endelig bedt kommunen om å få innsyn -i dette notatet, og det ble oversendt på 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 måtte betalt minst 9 millioner -for å gå over til Windows på skolene. I tillegg dokumenterer notatet -at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux. -Jeg anbefaler alle å lese de 10 sidene med gode argumenter for å kutte -unødige utgifter på IT i skoleverket. :)

It has been a while since my last update. Since last summer, I +have worked on a Norwegian +docbook version of the 2004 book +Free Culture by Lawrence Lessig, +to get a Norwegian text explaining the problems with the copyright +law. Yesterday, I finally broken the 90% mark, when counting the +number of strings to translate. Due to real life constraints, I have +not had time to work on it since March, but when the summer broke out, +I found time to work on it again. Still lots of work left, but the +first draft is nearing completion. I created a graph to show the +progress of the translation:

+ +

+ +

When the first draft is done, the translated text need to be +proof read, and the remaining formatting problems with images and SVG +drawings need to be fixed. There are probably also some index entries +missing that need to be added. This can be done by comparing the +index entries listed in the SiSU version of the book, or comparing the +English docbook version with the paper version. Last, the colophon +page with ISBN numbers etc need to be wrapped up before the release is +done. I should also figure out how to get correct Norwegian sorting +of the index pages. All docbook tools I have tried so far (xmlto, +docbook-xsl, dblatex) get the order of symbols and the special +Norwegian letters ÆØÅ wrong.

+ +

There is still need for translators and people with docbook +knowledge, to be able to get a good looking book (I still struggle +with dblatex, xmlto and docbook-xsl) as well as to do the draft +translation and proof reading. And I would like the figures to be +redrawn as SVGs to make it easy to translate them. Any SVG master +around? There are also some legal terms that are unfamiliar to me. +If you want to help, please get in touch with me, and check out the +project files currently available from +github.

+ +

If you are curious what the translated book currently look like, +the updated +PDF +and +EPUB +are published on github. The HTML version is published as well, but +github hand it out with MIME type text/plain, confusing browsers, so I +saw no point in linking to that version.

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.

For noen uker siden, innen fristen 2013-04-15, leverte jeg og -Morten Kjelkenes vårt bidrag til -DIFIs apps4norge-konkurranse -under lagnavnet NUUGs tannlegeteam. -Vi leverte følgende i idé-kategorien:

- -
- -

Tittel: Stikk innom tannlegen

- -

- -

Beskrivelse:

- -

Idéen - -

Gjøre det enklere å 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 å oppgi hvor en bor og jobber, og få forslag til -tannleger både i nærheten og på veien mellom disse stedene.

- -

Brukeren oppgir hjemmeadresse og jobbadresse, og kanskje også -barnehage. Så kan en også oppgi egen timelønn (for å beregne taps -arbeidsfortjeneste) og om en reiser med kollektivt, til fots eller -kjører bil. Så trykker en søk, og får 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 sorteringsrekkefølge for listen ved å -trykke på aktuell kolonne, og velge om en skal sortere på pris, -reisetid eller totalkostnad. Kun tannleger som tar imot nye kunder tas -i utganspunktet med i listen. Når brukeren trykker med musa en -tannlegemarkør på 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 å finne reisebeskrivelse, åpningstider, etc.

- -

Nytteverdi for brukeren

- -
    -
  • sparer tid pÃ¥ tannlegebesøk
  • -
  • 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 nærheten, pÃ¥ tvers av kommunegrenser

Felles er at den gjør tannlegen lettere tilgjengelig for de som vil spare tid eller penger.

+
  • Switched roaming workstation profiles from wicd to network-manager + for network configuration, as wicd didn't work any more.
  • +
  • Changed version numbers of patched gosa and libpam-mklocaluser + packages to make sure our locally patched versions will be replaced + by the official packages when they are released from Debian. Those + installing alpha version need to reinstall or manually downgrade gosa + and libpam-mklocaluser.
  • +
  • Added bluetooth tools to the default desktop (bluedevil, blueman).
  • +
  • Added tools for sharing the desktop on KDE (krdc, krfb).
  • +
  • Added valgrind to the default installation for easier debugging of + crash bugs.

    X-faktor - “Det lille ekstra...”

    +
      -

      Denne tjenesten gir det lille ekstra ved at den ikke slår opp -avstand til tannlege fra et enkelt punkt men avstand fra en reisevei, -slik at en får flere tannleger å velge imellom og kanskje kan spare -enda mer tid og penger enn en ville gjort ved å sjekke kun de nærmest -hjemme eller jobb.

    • Fixed artwork package to work with gnome, no longer break + desktop=gnome installations.
    • +
    • Adjusted installer to now work when forced to use a proxy with the + netinst CD.
    • +
    • Fixed code detecting and setting/loading hardware specific + setup/firmware to work more robust out of the box.
    • +
    • Adjusted Kerberos setup to detect realm and server settings at + install time instead of dynamically at run time. This avoid a crash + with krb5-auth-dialog on diskless workstations without a DNS name.
    • +
    • Worked around misfeature in network-manager not calling the dhclient + exit hooks, causing automatic proxy configuration and automatic host + name setting at run time to work again.
    • +
    • Fixed feature setting the default Iceweasel start page from URL + fetched from LDAP, to allow schools to set the global default by + updating the dc=skole,dc=skolelinux,dc=no LDAP object.
    • +
    • Changed default host name on all networked machines to be unique + (generated from MAC or reverse DNS) after boot.
    • +
    • Adjusted partition sizes to make sure they are big enough.

    New features for Debian Edu ~7.0.0 alpha0 released -2013-04-26

    + +

    +

    Today I switched to +my +new laptop. I've previously written about the problems I had with +my new Thinkpad X230, which was delivered with an +180 +GB Intel SSD disk with Lenovo firmware that did not handle +sustained writes. My hardware supplier have been very forthcoming in +trying to find a solution, and after first trying with another +identical 180 GB disks they decided to send me a 256 GB Samsung SSD +disk instead to fix it once and for all. The Samsung disk survived +the installation of Debian with encrypted disks (filling the disk with +random data during installation killed the first two), and I thus +decided to trust it with my data. I have installed it as a Debian Edu +Wheezy roaming workstation hooked up with my Debian Edu Squeeze main +server at home using Kerberos and LDAP, and will use it as my work +station from now on.

    + +

    As this is a solid state disk with no moving parts, I believe the +Debian Wheezy default installation need to be tuned a bit to increase +performance and increase life time of the disk. The Linux kernel and +user space applications do not yet adjust automatically to such +environment. To make it easier for my self, I created a draft Debian +package ssd-setup to handle this tuning. The +source +for the ssd-setup package is available from collab-maint, and it +is set up to adjust the setup of the machine by just installing the +package. If there is any non-SSD disk in the machine, the package +will refuse to install, as I did not try to write any logic to sort +file systems in SSD and non-SSD file systems.

    + +

    I consider the package a draft, as I am a bit unsure how to best +set up Debian Wheezy with an SSD. It is adjusted to my use case, +where I set up the machine with one large encrypted partition (in +addition to /boot), put LVM on top of this and set up partitions on +top of this again. See the README file in the package source for the +references I used to pick the settings. At the moment these +parameters are tuned:

      How to report bugs

      +

      During installation, I cancelled the part where the installer fill +the disk with random data, as this would kill the SSD performance for +little gain. My goal with the encrypted file system is to ensure +those stealing my laptop end up with a brick and not a working +computer. I have no hope in keeping the really resourceful people +from getting the data on the disk (see +XKCD #538 for an explanation why). +Thus I concluded that adding the discard option to crypttab is the +right thing to do.

      + +

      I considered using the noop I/O scheduler, as several recommended +it for SSD, but others recommended deadline and a benchmark I found +indicated that deadline might be better for interactive use.

      + +

      I also considered using the 'discard' file system option for ext3 +and ext4, but read that it would give a performance hit ever time a +file is removed, and thought it best to that that slowdown once a day +instead of during my work.

      + +

      My package do not set up tmpfs on /var/run, /var/lock and /tmp, as +this is already done by Debian Edu.

      + +

      I have not yet started on the user space tuning. I expect +iceweasel need some tuning, and perhaps other applications too, but +have not yet had time to investigate those parts.

      + +

      The package should work on Ubuntu too, but I have not yet tested it +there.

      + +

      As for the answer to the question in the title of this blog post, +as far as I know, the only solution I know about is to replace the +disk. It might be possible to flash it with Intel firmware instead of +the Lenovo firmware. But I have not tried and did not want to do so +without approval from Lenovo as I wanted to keep the warranty on the +disk until a solution was found and they wanted the broken disks +back.

    Bitcoin er mye i mediene for -tiden. Jeg følger med via Mylder for å finne -artikler som omtaler -temaet, og takket være dette oppdaget jeg at stortingsrepresentant -Ketil Solvik-Olsen fra FrP nylig har spurt finansminister Sigbjørn -Johnsen om hans syn på Bitcoin, og -fått -svar for noen dager siden. Jeg bet meg spesielt merke til -følgende formulering fra finansministeren:

    - -

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

    - -

    At Bitcoin er anonymt er en myte som spres av både journalister og -andre, så det er ikke veldig overraskende at også finansministeren har -gått på limpinnen. Det er dog litt rart, da jeg håper at -finansdepartementet ikke baserer seg på rykter og myter når de -besvarer Stortinget. Men du trenger ikke bare tro på meg som kilde -til påstanden om at Bitcoin ikke er anonymt. Sondre Rønjom har -via Sikkerhetsbloggen -hos Nasjonal Sikkerhetsmyndighet uttalt følgende:

    - -

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

    - -

    Enhver bevegelse av Bitcoin er offentlig tilgjengelig for alle på -Internet, og en må legge svært mye innsats inn hvis en skal hindre at -nettverksanalyse av transaksjonsloggene kan brukes til å identifisere -brukerne. F.eks. kan en enkelt se hva jeg har mottatt til min -offentliggjorte mottaksadresse ved å besøke blockexplorer og slå opp -adressen -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b. -Det virker dermed på meg ganske klart at å påstå at -Bitcoin-transaksjoner er anonyme strengt tatt er å føre Stortinget bak -lyset.

    - -

    Finansministeren er ikke den eneste som har latt seg forlede av -medieomtalen. I spørsmålet fra Hr. Solvik-Olsen skriver han at «For -noen dager siden kom den første bitcoin-minibanken på Kypros», hvilket -så vidt jeg har klart å 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.

    A few days ago, I wrote about +the +problems I experienced with my new X230 and its SSD disk, which +was dying during installation because it is unable to cope with +sustained write. My supplier is in contact with +Lenovo, and they wanted to send a +replacement disk to try to fix the problem. They decided to send an +identical model, so my hopes for a permanent fix was slim.

    + +

    Anyway, today I got the replacement disk and tried to install +Debian Edu Wheezy with encrypted disk on it. The new disk have the +same firmware version as the original. This time my hope raised +slightly as the installation progressed, as the original disk used to +die after 4-7% of the disk was written to, while this time it kept +going past 10%, 20%, 40% and even past 50%. But around 60%, the disk +died again and I was back on square one. I still do not have a new +laptop with a disk I can trust. I can not live with a disk that might +lock up when I download a new +Debian Edu / Skolelinux ISO or +other large files. I look forward to hearing from my supplier with +the next proposal from Lenovo.

    + +

    The original disk is marked Intel SSD 520 Series 180 GB, +11S0C38722Z1ZNME35X1TR, ISN: CVCV321407HB180EGN, SA: G57560302, FW: +LF1i, 29MAY2013, PBA: G39779-300, LBA 351,651,888, LI P/N: 0C38722, +Pb-free 2LI, LC P/N: 16-200366, WWN: 55CD2E40002756C4, Model: +SSDSC2BW180A3L 2.5" 6Gb/s SATA SSD 180G 5V 1A, ASM P/N 0C38732, FRU +P/N 45N8295, P0C38732.

    Half a year ago, I reported that I had to find a +replacement +for my trusty old Thinkpad X41. Unfortunately I did not have much +time to spend on it, and it took a while to find a model I believe +will do the job, but two days ago the replacement finally arrived. I +ended up picking a +Thinkpad X230 +with SSD disk (NZDAJMN). I first test installed Debian Edu Wheezy as +a roaming workstation, and it seemed to work flawlessly. But my +second installation with encrypted disk was not as successful. More +on that below.

    + +

    I had a hard time trying to track down a good laptop, as my most +important requirements (robust and with a good keyboard) are never +listed in the feature list. But I did get good help from the search +feature at Prisjakt, which +allowed me to limit the list of interesting laptops based on my other +requirements. A bit surprising that SSD disk are not disks according +to that search interface, so I had to drop specifying the number of +disks from my search parameters. I also asked around among friends to +get their impression on keyboards and robustness.

    + +

    So the new laptop arrived, and it is quite a lot wider than the +X41. I am not quite convinced about the keyboard, as it is +significantly wider than my old keyboard, and I have to stretch my +hand a lot more to reach the edges. But the key response is fairly +good and the individual key shape is fairly easy to handle, so I hope +I will get used to it. My old X40 was starting to fail, and I really +needed a new laptop now. :)

    + +

    Turning off the touch pad was simple. All it took was a quick +visit to the BIOS during boot it disable it.

    + +

    But there is a fatal problem with the laptop. The 180 GB SSD disk +lock up during load. And this happen when installing Debian Wheezy +with encrypted disk, while the disk is being filled with random data. +I also tested to install Ubuntu Raring, and it happen there too if I +reenable the code to fill the disk with random data (it is disabled by +default in Ubuntu). And the bug with is already known. It was +reported to Debian as BTS +report #691427 2012-10-25 (journal commit I/O error on brand-new +Thinkpad T430s ext4 on lvm on SSD). It is also reported to the Linux +kernel developers as +Kernel bugzilla +report #51861 2012-12-20 (Intel SSD 520 stops working under load +(SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the +Lenovo forums, both for +T430 +2012-11-10 and for +X230 +03-20-2013. The problem do not only affect installation. The +reports state that the disk lock up during use if many writes are done +on the disk, so it is much no use to work around the installation +problem and end up with a computer that can lock up at any moment. +There is even a +small C program +available that will lock up the hard drive after running a few +minutes by writing to a file.

    + +

    I've contacted my supplier and asked how to handle this, and after +contacting PCHELP Norway (request 01D1FDP) which handle support +requests for Lenovo, his first suggestion was to upgrade the disk +firmware. Unfortunately there is no newer firmware available from +Lenovo, as my disk already have the most recent one (version LF1i). I +hope to hear more from him today and hope the problem can be +fixed. :)

      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. Immediately 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. The provided school server provides LDAP +database and Kerberos authentication service, centralized home +directories, DHCP server, web proxy and many other services. The +desktop contains +more +than 60 educational software packages and more are available from +the Debian archive, and schools can choose between KDE, Gnome, LXDE +and Xfce desktop environment.

      + +

      This is the fourth test release based on Debian Wheezy. Basically +this is an updated and slightly improved version compared to the +Squeeze release.

      +

      Software updates

      +
        +
      • Dropped ispell dictionaries from our default installation.
      • +
      • Dropped menu-xdg from the KDE desktop option, to drop the Debian + submenu. It was not included with Gnome, LXDE or Xfce, so this + brings KDE in line with the others.
      • +
      • Dropped xdrawchem, xjig and xsok from our default installation as + they don't have a desktop menu entry and thus won't show up in the + menu now that menu-xdg was removed.
      • +
      • Removed the killer system to kill left behind processes on + multi-user machines, as it was no longer able to understand when a + X display was in use and killed the processes of the active users + too.
      • +
      • Dropped the golearn (from goplay) package as the debtags in wheezy + are too few to make the package useful.

    For en stund tilbake gikk nyheten om -Sandy -Island, en øy som var dukket opp på noen kart, men som ikke var -synlig når en sjekket den på satellittbilder. Dagbladet meldte for -eksempel at -«denne -øya finnes på kart, men ikke i virkeligheten». Noe senere begynte -jeg å lese -historier -om Ruffen til mine barn. Dette er historier om sjøormen Ruffen -skapt av Tor Åge Bringsværd, som starter med følgende beskrivelse:

    - -

    -«Langt ute i havet ligger en mystisk øy. Den er bare synlig hver -tirsdag og fredag. Derfor står den ikke på noe kart. På denne øya -ligger et slott, og i slottet bor en gammel, fin sjøormfamilie.» -

    - -

    Det virker åpenbart at Hr. Bringsværd tok feil når han trodde den -ikke var på noe kart, og at noen tydeligvis har vært i nærheten en -tirsdag eller en fredag og fått den med på et kart, mens -satellittbildene er tatt på noen av de fem andre dagene i uka og -dermed ikke ser øya. :)

    - -

    I følge -en -senere artikkel i Dagbladet hevder Shaun Higgins, en forsker fra -New Zealand, at et hvalfangstskip fra 1876 er opprinnelsen til at -spøkelsesøya i det hele tatt havnet på kartet. Det fremgår ikke fra -historien hvilken ukedag de var innom.

    Jeg har stor sans for Tor Åge Bringsværd. Og han viste nylig en -svært fin side av seg selv da han sa ja til EFNs forespørsel om å gi -ut novellen Kodémus med -Creative Commons-lisens.
