Skolelinux-intervju: Nirosan Thiyagalingam
-
24th May 2013
-

En ting -Skolelinux-prosjektet har -hatt mye glede av er studentprosjekter. F.eks. er -stillbildeanimasjonssystemet -Stopmotion resultat av et studentprosjekt i Skolelinux. De siste -månedene har en ivrig student veiledet av Marius Kotsbak i -FRiSK testet hva en -kan få til med en datamaskin til NOK 400,- (antagelig 1700,- med -skjerm, tastatur og mus) når det brukes i Skolelinux. Jeg spurte han -om et intervju.

- -

Hvem er du, og hva driver du med til daglig?

- -

Jeg heter Nirosan Thiyagalingam. Jeg er 24 år og studerer -dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for -data har siden ung alder vært tilstede og jeg har i tillegg alltid -vært glad i å lære nye ting. Med teknologi som endres svært hurtig er -det alltid noe nytt å lære. Noe som igjen har gjort det svært -interessant å følge med på utviklingen. Jeg valgte dataingeniør -studiet grunnet ønske om å lære enda mer om programmering og utvikling -av store systemer.

- -

Hvordan kom du i kontakt med Skolelinux-prosjektet?

- -

Skolelinux prosjektet hørte jeg først om i media. Men det var først -når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for -prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine -hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og -jeg valgte derfor en oppgave som gikk ut på å få en -Raspberry PI. Altså en -ultra-billig datamaskin til å kjøre Debian Edu på lik linje med -vanlige datamaskiner. I løpet av prosjektet ble det gjort mye -forskning på nettet. Det var mye jeg måtte forstå rundt hvordan -operativsystemet Linux fungerte før jeg kunne angripe -problemet. Prøvde først å finne ut hvordan man kunne transformere en -vanlig installasjon av Skolelinux til Raspberry PI, men dette var -altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble -videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk -diskutert hvilken retning jeg burde gå for å få til en fullverdig -løsning. Det ble bestemt at jeg skulle gå for å først installere -Raspian. Dette er et -operativsystem basert på Debian spesiallaget for Raspberry Pi sin -maskinvare. Nå som Debian var installert på datamaskinen gjenstod det -å installere de nødvendige Skolelinux pakkene for å få til et -fullverdig system. Disse pakkene ble installert manuelt i første -omgang, men ble senere installert automatisk via et script som Petter -Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i -gang med installasjonen i løpet av bare 5 minutter. Ikke nok med det, -alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med -resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak -maskin og det merkes godt når man har installert Skolelinux på -den. Video og 3D-rendering fungerer utrolig dårlig, men nettsurfing og -kontorprogrammer fungerer godt. Det kan derfor konkluderes med at -datamaskinen er egnet for enkle oppgaver. - -

Jeg syns det er viktig påpeke at dette kun er startfasen av en slik -løsning. På markedet finnes det nå maskiner som har bedre hardware enn -Raspberry Pi. Det er store muligheter for at man kan klare å -installere Skolelinux på disse også, og da forsvinner nok mest -sannsynlig ytelsesproblemene med Video og 3D rendering også.

- -

Det ble også prøvd med en løsning som gjorde at Raspberry Pi -fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse -med tanke på hastighet og brukeropplevelse. Men også her var video og -3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt -BerryTerminal for å få til -dette.

- -

Hva er fordelene med Skolelinux slik du ser det?

- -

Fordelen med Skolelinux er mange. At det er gratis er en stor -fordel, men at det er så mange som er med på å utvikle det og -vedlikeholde det er en enda større fordel. Allerede før jeg startet -med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen -så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet -hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de -nødvendige programmene og funksjonen som både små og store skoler i -tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en -så komplett løsning er en kjempefordel. Installasjonen er knirkefri -og det er svært enkelt å installere og komme i gang.

- -

Hva er ulempene med Skolelinux slik du ser det?

- -

Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv -om websidene er enkle og konsise er det allikevel ikke appellerende i -like stor grad som for eksempel -Ubuntu sine sider. Deres side -tilbyr, i tillegg til godt design og presentasjon, en nettbasert -emulator av deres operativsystem. Dette er en stor fordel slik jeg ser -det. Bortsett fra dette ser jeg absolutt ingen ulemper med -Skolelinux-prosjektet.

- -

Hvilken fri programvare bruker du til daglig?

- -

Til daglig er jeg en flittig bruker av det åpne media -sentersystemet XBMC. Det enorme -samfunnet rundt dette prosjektet har gjort dette til et program som -dekker alles behov. Man kan tilpasse det akkurat slik man vil både med -tanke på utseende og funksjoner ved installere plug-ins eller -scripts.

- -

Hvilken strategi tror du er den rette å bruke for å få -skoler til å ta i bruk fri programvare?

- -

Strategien som burde brukes sett fra mine øyne er -markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn -i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe -annet som koster de store summer. At skolelinux til de grader tilbyr -en så komplett løsning bure komme frem. Enten via reklamekampanjer -eller ved å sende ut folk til skoler for så å la skolenettverk -ansvarlige får teste ut hvordan Skolelinux fungerer i praksis. Om det -i tillegg ble utviklet gode websider og en emulator for å la brukere -prøve operativsystemet ville nok dette ha styrket inntrykket -betraktelig.

10th September 2013

I was introduced to the +Freedombox project +in 2010, when Eben Moglen presented his vision about serving the need +of non-technical people to keep their personal information private and +within the legal protection of their own homes. The idea is to give +people back the power over their network and machines, and return +Internet back to its intended peer-to-peer architecture. Instead of +depending on a central service, the Freedombox will give everyone +control over their own basic infrastructure.

+ +

I've intended to join the effort since then, but other tasks have +taken priority. But this summers nasty news about the misuse of trust +and privilege exercised by the "western" intelligence gathering +communities increased my eagerness to contribute to a point where I +actually started working on the project a while back.

+ +

The initial +Debian initiative based on the vision from Eben Moglen, is to +create a simple and cheap Debian based appliance that anyone can hook +up in their home and get access to secure and private services and +communication. The initial deployment platform have been the +Dreamplug, +which is a piece of hardware I do not own. So to be able to test what +the current Freedombox setup, I had to come up with a way to install +it on some hardware I do got access to. I have rewritten the +freedom-maker +image build framework to use .deb packages instead of only copying +setup into the boot images, and thanks to this rewrite I am able to +set up any machine supported by Debian Wheezy as a Freedombox, using +the previously mentioned deb (and a few support debs for packages +missing in Debian).

+ +

The current Freedombox setup consist of a set of bootstrapping +scripts +(freedombox-setup), +and a administrative web interface +(plinth + exmachina + +withsqlite), as well as a privacy enhancing proxy based on +privoxy +(freedombox-privoxy). There is also a web/javascript based XMPP +client (jwchat) +trying (unsuccessfully so far) to talk to the XMPP server +(ejabberd). The +web interface is pluggable, and the goal is to use it to enable OpenID +services, mesh network connectivity, use of TOR, etc, etc. Not much of +this is really working yet, see +the +project TODO for links to GIT repositories. Most of the code is +on github at the moment. The HTTP proxy is operational out of the +box, and the admin web interface can be used to add/remove plinth +users. I've not been able to do anything else with it so far, but +know there are several branches spread around github and other places +with lots of half baked features.

+ +

Anyway, if you want to have a look at the current stat, the +following recipes should work to give you a test machine to poke +at.

+ +

Debian Wheezy amd64

+ +
    + +
  1. Fetch normal Debian Wheezy installation ISO.
  2. +
  3. Boot from it, either as CD or USB stick.
  4. +
  5. Press [tab] on the boot prompt and add this as a boot argument +to the Debian installer:

    +

    url=http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat
  6. + +
  7. Answer the few language/region/password questions and pick disk to +install on.
  8. + +
  9. When the installation is finished and the machine have rebooted a +few times, your Freedombox is ready for testing.
  10. + +
+ +

Raspberry Pi Raspbian

+ +
    + +
  1. Fetch a Raspbian SD card image, create SD card.
  2. +
  3. Boot from SD card, extend file system to fill the card completely.
  4. +
  5. Log in and add this to /etc/sources.list:

    +
    +deb http://www.reinholdtsen.name/freedombox wheezy main
    +
  6. +
  7. Run this as root:

    +
    +wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
    +   apt-key add -
    +apt-get update
    +apt-get install freedombox-setup
    +/usr/lib/freedombox/setup
    +
  8. +
  9. Reboot into your freshly created Freedombox.
  10. + +
+ +

You can test it on other architectures too, but because the +freedombox-privoxy package is binary, it will only work as intended on +the architectures where I have had time to build the binary and put it +in my APT repository. But do not let this stop you. It is only a +short "apt-get source -b freedombox-privoxy" away. :)

+ +

Note that by default Freedombox is a DHCP server on the +192.168.1.0/24 subnet, so if this is your subnet be careful and turn +off the DHCP server by running "update-rc.d isc-dhcp-server +disable" as root.

+ +

Please let me know if this work for you, or if you have any +problems. We gather on the IRC channel +#freedombox on +irc.debian.org and the +project +mailing list.

+ +

Once you get your freedombox operational, you can visit +http://your-host-name:8001/ to see the state of the plint +welcome screen (dead end - do not be surprised if you are unable to +get past it), and next visit http://your-host-name:8001/help/ +to look at the rest of plinth. The default user is 'admin' and the +default password is 'secret'.

Debian Edu / Skolelinux is -an operating system based on Debian intended for use in schools. It -contain a turn-key solution for the computer network provided to -pupils in the primary schools.

I 2011 raderte et stortingsflertall bestående av Høyre og +Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske +folk. Det ble vedtatt at det skulle registreres og lagres i et halvt +år hvor alle som bærer på en mobiltelefon befinner seg, hvem de +snakker med og hvor lenge de snakket sammen. Det skal også +registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost +til, og hvilke nett-tjenere en besøkte. Saken er kjent som +Datalagringsdirektivet +(DLD), og innebærer at alle innbyggerne og andre innenfor Norges +grenser overvåkes døgnet rundt. Det ble i praksis innført brev og +besøkskontroll av hele befolkningen. Rapporter fra de landene som +allerede har innført slik total lagring av borgernes +kommunikasjonsmønstre forteller at det ikke hjelper i +kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre +millioner, uten at det ser ut til å bidra positivt til politiets +arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt +på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen. +Se mer på +Wikipedia +og Jon Wessel-Aas.

+ +

Hva er problemet, tenkter du kanskje? Et åpenbart problem er at +medienes kildevern i praksis blir radert ut. Den innsamlede +informasjonen gjør det mulig å finne ut hvem som har snakket med +journalister på telefon, SMS og epost, og hvem som har vært i nærheten +av journalister så sant begge bar med seg en telefon. Et annet er at +advokatvernet blir sterkt redusert, der politiet kan finne ut hvem +som har snakket med en advokat når, eller vært i møter en med advokat. +Et tredje er at svært personlig informasjon kan avledes fra hvilke +nettsteder en har besøkt. Har en besøkt hivnorge.no, +swingersnorge.com eller andre sider som kan brukes til avlede +interesser som hører til privatsfæren, vil denne informasjonen være +tilgjengelig takket være datalagringsdirektivet.

+ +

De fleste partiene var mot, kun to partier stemte for. Høyre og +Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har +DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre +fylkene). Det er dermed helt uaktuelt for meg å stemme på disse +partiene.

    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!).

    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. :)

    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.

    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.

    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.

    +

    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 fifth 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.

    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.

    • +
    • 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.

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

    + +
    17th July 2013
    +

    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.

    - -

    Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til -mine aktiviteter, så setter jeg pris på Bitcoin-donasjoner til min -adresse -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.

    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. :)
