  26 <p>The last few days I have been looking into the status of the LDAP
  27 directory in Debian Edu, and in the process I started to miss a GUI
  28 tool to browse the LDAP tree.  The only one I was able to find in
  29 Debian/Squeeze and Lenny is
  30 <a href="http://luma.sourceforge.net/">LUMA</a>, which has proved to
  31 be a great tool to get a overview of the current LDAP directory
  32 populated by default in Skolelinux.  Thanks to it, I have been able to
  33 find empty and obsolete subtrees, misplaced objects and duplicate
  34 objects.  It will be installed by default in Debian/Squeeze.  If you
  35 are working with LDAP, give it a go. :)</p>
  36
  37 <p>I did notice one problem with it I have not had time to report to
  38 the BTS yet.  There is no .desktop file in the package, so the tool do
  39 not show up in the Gnome and KDE menus, but only deep down in in the
  40 Debian submenu in KDE.  I hope that can be fixed before Squeeze is
  41 released.</p>
  42
  43 <p>I have not yet been able to get it to modify the tree yet.  I would
  44 like to move objects and remove subtrees directly in the GUI, but have
  45 not found a way to do that with LUMA yet.  So in the mean time, I use
  46 <a href="http://www.lichteblau.com/ldapvi/">ldapvi</a> for that.</p>
  47
  48 <p>If you have tips on other GUI tools for LDAP that might be useful
  49 in Debian Edu, please contact us on debian-edu@lists.debian.org.</p>

  65 <p>A while back, I
  66 <a href="http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html">complained
  67 about the fact</a> that it is not possible with the provided schemas
  68 for storing DNS and DHCP information in LDAP to combine the two sets
  69 of information into one LDAP object representing a computer.</p>
  70
  71 <p>In the mean time, I discovered that a simple fix would be to make
  72 the dhcpHost object class auxiliary, to allow it to be combined with
  73 the dNSDomain object class, and thus forming one object for one
  74 computer when storing both DHCP and DNS information in LDAP.</p>
  75
  76 <p>If I understand this correctly, it is not safe to do this change
  77 without also changing the assigned number for the object class, and I
  78 do not know enough about LDAP schema design to do that properly for
  79 Debian Edu.</p>
  80
  81 <p>Anyway, for future reference, this is how I believe we could change
  82 the
  83 <a href="http://tools.ietf.org/html/draft-ietf-dhc-ldap-schema-00">DHCP
  84 schema</a> to solve at least part of the problem with the LDAP schemas
  85 available today from IETF.</p>

 101 <p>I very much welcome clues on how to do this properly for Debian

 120   <div class="date">2010-06-16 14:55</div>
 121   <div class="body">
 122 <p>A few times I have had the need to simulate the way tasksel
 123 installs packages during the normal debian-installer run.  Until now,
 124 I have ended up letting tasksel do the work, with the annoying problem
 125 of not getting any feedback at all when something fails (like a
 126 conffile question from dpkg or a download that fails), using code like
 127 this:
 128
 129 <blockquote><pre>
 130 export DEBIAN_FRONTEND=noninteractive
 131 tasksel --new-install
 132 </pre></blockquote>
 133
 134 This would invoke tasksel, let its automatic task selection pick the
 135 tasks to install, and continue to install the requested tasks without
 136 any output what so ever.
 137
 138 Recently I revisited this problem while working on the automatic
 139 package upgrade testing, because tasksel would some times hang without
 140 any useful feedback, and I want to see what is going on when it
 141 happen.  Then it occured to me, I can parse the output from tasksel
 142 when asked to run in test mode, and use that aptitude command line
 143 printed by tasksel then to simulate the tasksel run.  I ended up using
 144 code like this:
 145
 146 <blockquote><pre>
 147 export DEBIAN_FRONTEND=noninteractive
 148 cmd="$(in_target tasksel -t --new-install | sed 's/debconf-apt-progress -- //')"
 149 $cmd
 150 </pre></blockquote>
 151
 152 <p>The content of $cmd is typically something like "<tt>aptitude -q
 153 --without-recommends -o APT::Install-Recommends=no -y install
 154 ~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired
 155 ~pimportant</tt>", which will install the gnome desktop task, the
 156 laptop task and all packages with priority standard , required and
 157 important, just like tasksel would have done it during
 158 installation.</p>
 159
 160 <p>A better approach is probably to extend tasksel to be able to
 161 install packages without using debconf-apt-progress, for use cases
 162 like this.</p>

 178 <p><a href="http://www.dagbladet.no/2010/06/16/nyheter/innenriks/streik/arbeidsliv/12157858/">Dagbladet
 179 melder</a> at Vinmonopolet med bakgrunn i vekterstreiken som pågår i
 180 Norge for tiden, har bestemt seg for med vitende og vilje å bryte
 181 sentralbanklovens paragraf 14 ved å nekte folk å betale med
 182 kontanter, og at flere butikker planlegger å følge deres eksempel.
 183 Jeg synes det er hårreisende hvis de slipper unna med et slikt
 184 soleklart lovbrudd, og lurer på hva slags muligheter jeg vil ha hvis
 185 jeg blir nektet å handle med kontanter.  Jeg handler i hovedsak med
 186 kontanter selv, da jeg anser det som en borgerrett å kunne handle
 187 anonymt uten at det blir registrert.  For meg er det et angrep på mitt
 188 personvern å nekte å ta imot kontant betaling.</p>
 189
 190 <p><a href="http://www.lovdata.no/all/tl-19850524-028-003.html#14">Paragrafen
 191 i sentralbankloven</a> lyder:</p>
 192
 193 <blockquote>
 194 <p>§ 14. Tvungent betalingsmiddel</p>
 195
 196 <p>Bankens sedler og mynter er tvungent betalingsmiddel i Norge. Ingen
 197 er pliktig til i én betaling å ta imot mer enn femogtyve mynter av
 198 hver enhet.</p>
 199
 200 <p>Sterkt skadde sedler og mynter er ikke tvungent
 201 betalingsmiddel. Banken gir nærmere forskrifter om erstatning for
 202 bortkomne, brente eller skadde sedler og mynter.</p>
 203
 204 <p>Selv om en avtale inneholder klausul om betaling av en
 205 pengeforpliktelse i gullverdi, kan skyldneren frigjøre seg med tvungne
 206 betalingsmidler uten hensyn til denne klausul.</p>
 207 </blockquote>
 208
 209 <p>Det er med bakgrunn i denne lovet ikke tillatt å nekte å ta imot
 210 kontakt betaling.  Det er en lov jeg har sans for, og som jeg mener må
 211 håndheves strengt.</p>

 227 <p>For those of us caring about document exchange and
 228 interoperability, <a href="http://www.officeshots.org/">OfficeShots</a>
 229 is a great service.  It is to ODF documents what
 230 <a href="http://browsershots.org/">BrowserShots</a> is for web
 231 pages.</p>
 232
 233 <p>A while back, I was contacted by Knut Yrvin at the part of Nokia
 234 that used to be Trolltech, who wanted to help the OfficeShots project
 235 and wondered if the University of Oslo where I work would be
 236 interested in supporting the project.  I helped him to navigate his
 237 request to the right people at work, and his request was answered with
 238 a spot in the machine room with power and network connected, and Knut
 239 arranged funding for a machine to fill the spot.  The machine is
 240 administrated by the OfficeShots people, so I do not have daily
 241 contact with its progress, and thus from time to time check back to
 242 see how the project is doing.</p>
 243
 244 <p>Today I had a look, and was happy to see that the Dell box in our
 245 machine room now is the host for several virtual machines running as
 246 OfficeShots factories, and the project is able to render ODF documents
 247 in 17 different document processing implementation on Linux and
 248 Windows.  This is great.</p>

 264 <p>My
 265 <a href="http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html">testing
 266 of Debian upgrades</a> from Lenny to Squeeze continues, and I've
 267 finally made the upgrade logs available from
 268 <a href="http://people.skolelinux.org/pere/debian-upgrade-testing/">http://people.skolelinux.org/pere/debian-upgrade-testing/</a>.
 269 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
 270 apt and aptitude, and found their differences interesting.  This time
 271 I will only focus on their removal plans.</p>
 272
 273 <p>After installing a Gnome desktop and the laptop task, apt-get wants
 274 to remove 72 packages when dist-upgrading from Lenny to Squeeze.  The
 275 surprising part is that it want to remove xorg and all
 276 xserver-xorg-video* drivers.  Clearly not a good choice, but I am not
 277 sure why.  When asking aptitude to do the same, it want to remove 129
 278 packages, but most of them are library packages I suspect are no
 279 longer needed.  Both of them want to remove bluetooth packages, which
 280 I do not know.  Perhaps these bluetooth packages are obsolete?</p>
 281
 282 <p>For KDE, apt-get want to remove 82 packages, among them kdebase
 283 which seem like a bad idea and xorg the same way as with Gnome. Asking
 284 aptitude for the same, it wants to remove 192 packages, none which are
 285 too surprising.</p>
 286
 287 <p>I guess the removal of xorg during upgrades should be investigated
 288 and avoided, and perhaps others as well.  Here are the complete list
 289 of planned removals.  The complete logs is available from the URL
 290 above.  Note if you want to repeat these tests, that the upgrade test
 291 for kde+apt-get hung in the tasksel setup because of dpkg asking
 292 conffile questions.  No idea why.  I worked around it by using
 293 '<tt>echo >> /proc/<em>pidofdpkg</em>/fd/0</tt>' to tell dpkg to
 294 continue.</p>

 448 <a href="http://yro.slashdot.org/story/10/06/11/1841256/Finland-To-Legalize-Use-of-Unsecured-Wi-Fi">Slashdot</a>
 449 at folk i Finland har forstått at åpne trådløsnett er et samfunnsgode.
 450 Jeg ser på åpne trådløsnett som et fellesgode på linje med retten til
 451 ferdsel i utmark og retten til å bevege seg i strandsonen.  Jeg har
 452 glede av åpne trådløsnett når jeg finner dem, og deler gladelig nett
 453 med andre så lenge de ikke forstyrrer min bruk av eget nett.
 454 Nettkapasiteten er sjelden en begrensning ved normal browsing og enkel
 455 SSH-innlogging (som er min vanligste nettbruk), og nett kan brukes til
 456 så mye positivt og nyttig (som nyhetslesing, sjekke været, kontakte
 457 slekt og venner, holde seg oppdatert om politiske saker, kontakte
 458 organisasjoner og politikere, etc), at det for meg er helt urimelig å
 459 blokkere dette for alle som ikke gjør en flue fortred.  De som mener
 460 at potensialet for misbruk er grunn nok til å hindre all den positive
 461 og lovlydige bruken av et åpent trådløsnett har jeg dermed ingen
 462 forståelse for.  En kan ikke eksistensen av forbrytere styre hvordan
 463 samfunnet skal organiseres.  Da får en et kontrollsamfunn de færreste
 464 ønsker å leve i, og det at vi har et samfunn i Norge der tilliten til
 465 hverandre er høy gjør at samfunnet fungerer ganske godt.  Det bør vi
 466 anstrenge oss for å beholde.</p>

 480   <div class="date">2010-06-11 22:50</div>
 481   <div class="body">
 482 <p>The last few days I have done some upgrade testing in Debian, to
 483 see if the upgrade from Lenny to Squeeze will go smoothly.  A few bugs
 484 have been discovered and reported in the process
 485 (<a href="http://bugs.debian.org/585410">#585410</a> in nagios3-cgi,
 486 <a href="http://bugs.debian.org/584879">#584879</a> already fixed in
 487 enscript and <a href="http://bugs.debian.org/584861">#584861</a> in
 488 kdebase-workspace-data), and to get a more regular testing going on, I
 489 am working on a script to automate the test.</p>
 490
 491 <p>The idea is to create a Lenny chroot and use tasksel to install a
 492 Gnome or KDE desktop installation inside the chroot before upgrading
 493 it.  To ensure no services are started in the chroot, a policy-rc.d
 494 script is inserted.  To make sure tasksel believe it is to install a
 495 desktop on a laptop, the tasksel tests are replaced in the chroot
 496 (only acceptable because this is a throw-away chroot).</p>
 497
 498 <p>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
 499 currently always fail because udev refuses to upgrade with the kernel
 500 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
 501 is created.  The bug report
 502 <a href="http://bugs.debian.org/566000">#566000</a> make me suspect
 503 this problem do not trigger in a chroot, but I touch the file anyway
 504 to make sure the upgrade go well.  Testing on virtual and real
 505 hardware have failed me because of udev so far, and creating this file
 506 do the trick in such settings anyway.  This is a
 507 <a href="http://www.linuxquestions.org/questions/debian-26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-804130/">known
 508 issue</a> and the current udev behaviour is intended by the udev
 509 maintainer because he lack the resources to rewrite udev to keep
 510 working with old kernels or something like that.  I really wish the
 511 udev upstream would keep udev backwards compatible, to avoid such
 512 upgrade problem, but given that they fail to do so, I guess
 513 documenting the way out of this mess is the best option we got for
 514 Debian Squeeze.</p>
 515
 516 <p>Anyway, back to the task at hand, testing upgrades.  This test
 517 script, which I call <tt>upgrade-test</tt> for now, is doing the
 518 trick:</p>
 519
 520 <blockquote><pre>

 576 chroot $tmpdir aptitude -y dist-upgrade
 577 fuser -mv
 578 </pre></blockquote>
 579
 580 <p>I suspect it would be useful to test upgrades with both apt-get and
 581 with aptitude, but I have not had time to look at how they behave
 582 differently so far.  I hope to get a cron job running to do the test
 583 regularly and post the result on the web.  The Gnome upgrade currently
 584 work, while the KDE upgrade fail because of the bug in
 585 kdebase-workspace-data</p>
 586
 587 <p>I am not quite sure what kind of extract from the huge upgrade logs
 588 (KDE 167 KiB, Gnome 516 KiB) it make sense to include in this blog
 589 post, so I will refrain from trying.  I can report that for Gnome,
 590 aptitude report 760 packages upgraded, 448 newly installed, 129 to
 591 remove and 1 not upgraded and 1024MB need to be downloaded while for
 592 KDE the same numbers are 702 packages upgraded, 507 newly installed,
 593 193 to remove and 0 not upgraded and 1117MB need to be downloaded</p>
 594
 595 <p>I am very happy to notice that the Gnome desktop + laptop upgrade
 596 is able to migrate to dependency based boot sequencing and parallel
 597 booting without a hitch.  Was unsure if there were still bugs with
 598 packages failing to clean up their obsolete init.d script during
 599 upgrades, and no such problem seem to affect the Gnome desktop+laptop
 600 packages.</p>

 616 <p>Det er merkelig hvordan myter om Skolelinux overlever.  En slik
 617 myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte
 618 tjenermaskiner.  I siste Computerworld Norge er
 619 <a href="http://www.idg.no/computerworld/article169432.ece">IT-sjef
 620 Viggo Billdal i Steinkjer intervjuet</a>, og forteller uten
 621 blygsel:</p>
 622
 623 <blockquote><p>Vi hadde Skolelinux, men det har vi sluttet med. Vi testet
 624 om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at
 625 Microsoft egentlig var totalt sett bedre egnet. Det var store
 626 driftskostnader med Skolelinux, blant annet på grunn av
 627 desentraliserte servere. Det var komplisert, så vi gikk vekk fra det
 628 og bruker nå bare Windows.</p></blockquote>
 629
 630 <p>En <a
 631 href="https://init.linpro.no/pipermail/skolelinux.no/bruker/2010-June/009101.html">rask
 632 sjekk</a> mot den norske brukerlista i Skolelinuxprosjektet forteller
 633 at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole
 634 i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen
 635 overkjørte skolen og krevde at de gikk over til Windows.  Et søk på
 636 nettet sendte meg til
 637 <a href="http://www.dn.no/multimedia/archive/00090/Dagens_it_nr__18_90826a.pdf">Dagens
 638 IT nr. 18 2005</a> hvor en kan lese på side 18:</p>
 639
 640 <blockquote><p>Inge Tømmerås ved Røysing skole i Steinkjer kjører ennå
 641 Microsoft, men forteller at kompetanseutfordringen med Skolelinux ikke
 642 var så stor.   Jeg syntes Skolelinux var utrolig lett å drifte uten
 643 forkunnskaper. Men man må jo selvsagt ha tilgang på ekstern kompetanse
 644 til installasjoner og maskinvarefeil, sier Tømmerås.</p></blockquote>
 645
 646 <p>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
 647 over påstanden om at Skolelinux krever desentraliserte tjenere.
 648 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
 649 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
 650 Den er modellert på nettverks- og tjenerløsningen som brukes på
 651 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
 652 driftstjenester.  Dette er det heldigvis noen som har fått med seg, og
 653 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
 654 artikkelen.  Min venn og gamle kollega Sturle Sunde forteller der:
 655
 656 <blockquote>
 657 <p>I Flora kommune køyrer vi Skulelinux på skular med alt frå 15 til
 658 meir enn 500 elevar. Dei store skulane har eigen tenar, for det er
 659 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
 660 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
 661 avhengige av eksterne linjer som er trege eller dyre. Dei minste
 662 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
 663 noko problem. Småskulane klarar seg fint med 1 mbit-linje til ein
 664 sentral tenar eller tenaren på ein større skule.</p>
 665
 666 <p>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
 667 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
 668 programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har
 669 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
 670 millionen. Det trengst to kommandoar på den sentrale tenaren for å
 671 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
 672 problem med diskar som ryk heller, som var eit problem før fordi
 673 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
 674 nettet, so det er fullt mogleg å køyre slike på småskular med trege
 675 linjer mot tenaren på ein større skule.</p>
 676
 677 <p>Flora kommune har nesten 800 Linux-maskiner i sitt skulenett, og
 678 ein person som tek seg av drift av heile nettet, inkludert tenarar,
 679 klientar, operativsystem, programvare, heimekontorløysing og
 680 administrasjon av brukarar.</p>
 681
 682 <p>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
 683 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
 684 var der frå før, og som har komplisert installasjonen vår. Etter at
 685 oppsettet var gjort har løysinga vore stabil og kravd minimalt med
 686 arbeid.</p>
 687 </blockquote>
 688
 689 <p>Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux
 690 sentraldriftes med sentrale tjenere.  Det forteller meg at Steinkjers
 691 IT-sjef neppe bør skylde på Skolelinux-løsningen for sine 5 år gamle
 692 minner.</p>

 707   <div class="body">
 708 <p>If Debian is to migrate to upstart on Linux, I expect some init.d
 709 scripts to migrate (some of) their operations to upstart job while
 710 keeping the init.d for hurd and kfreebsd.  The packages with such
 711 needs will need a way to get their init.d scripts to behave
 712 differently when used with sysvinit and with upstart.  Because of
 713 this, I had a look at the environment variables set when a init.d
 714 script is running under upstart, and when it is not.</p>
 715
 716 <p>With upstart, I notice these environment variables are set when a
 717 script is started from rcS.d/ (ignoring some irrelevant ones like
 718 COLUMNS):</p>
 719
 720 <blockquote><pre>
 721 DEFAULT_RUNLEVEL=2
 722 previous=N
 723 PREVLEVEL=
 724 RUNLEVEL=
 725 runlevel=S
 726 UPSTART_EVENTS=startup
 727 UPSTART_INSTANCE=
 728 UPSTART_JOB=rc-sysinit
 729 </pre></blockquote>
 730
 731 <p>With sysvinit, these environment variables are set for the same
 732 script.</p>
 733
 734 <blockquote><pre>
 735 INIT_VERSION=sysvinit-2.88
 736 previous=N
 737 PREVLEVEL=N
 738 RUNLEVEL=S
 739 runlevel=S
 740 </pre></blockquote>
 741
 742 <p>The RUNLEVEL and PREVLEVEL environment variables passed on from
 743 sysvinit are not set by upstart.  Not sure if it is intentional or not
 744 to not be compatible with sysvinit in this regard.</p>
 745
 746 <p>For scripts needing to behave differently when upstart is used,
 747 looking for the UPSTART_JOB environment variable seem to be a good
 748 choice.</p>
