  32         <p>It is strange to watch how a bug in Debian causing KDM to fail to
  33 start at boot when an NVidia video card is used is handled.  The
  34 problem seem to be that the nvidia X.org driver uses a long time to
  35 initialize, and this duration is longer than kdm is configured to
  36 wait.</p>
  37
  38 <p>I came across two bugs related to this issue,
  39 <a href="http://bugs.debian.org/583312">#583312</a> initially filed
  40 against initscripts and passed on to nvidia-glx when it became obvious
  41 that the nvidia drivers were involved, and
  42 <a href="http://bugs.debian.org/524751">#524751</a> initially filed against
  43 kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.</p>
  44
  45 <p>To me, it seem that no-one is interested in actually solving the
  46 problem nvidia video card owners experience and make sure the Debian
  47 distribution work out of the box for these users.  The nvidia driver
  48 maintainers expect kdm to be set up to wait longer, while kdm expect
  49 the nvidia driver maintainers to fix the driver to start faster, and
  50 while they wait for each other I guess the users end up switching to a
  51 distribution that work for them.  I have no idea what the solution is,
  52 but I am pretty sure that waiting for each other is not it.</p>
  53
  54 <p>I wonder why we end up handling bugs this way.</p>

 102         <p>When using sitesummary at a site to track machines, it is possible
 103 to get a list of the machine types in use thanks to the DMI
 104 information extracted from each machine.  The script to do so is
 105 included in the sitesummary package, and here is example output from
 106 the Skolelinux build servers:</p>
 107
 108 <blockquote><pre>
 109 maintainer:~# /usr/lib/sitesummary/hardware-model-summary
 110   vendor                    count
 111   Dell Computer Corporation     1
 112     PowerEdge 1750              1
 113   IBM                           1
 114     eserver xSeries 345 -[8670M1X]-     1
 115   Intel                         2
 116   [no-dmi-info]                 3
 117 maintainer:~#
 118 </pre></blockquote>
 119
 120 <p>The quality of the report depend on the quality of the DMI tables
 121 provided in each machine.  Here there are Intel machines without model
 122 information listed with Intel as vendor and no model, and virtual Xen
 123 machines listed as [no-dmi-info].  One can add -l as a command line
 124 option to list the individual machines.</p>
 125
 126 <p>A larger list is
 127 <a href="http://narvikskolen.no/sitesummary/">available from the the
 128 city of Narvik</a>, which uses Skolelinux on all their shools and also
 129 provide the basic sitesummary report publicly.  In their report there
 130 are ~1400 machines. I know they use both Ubuntu and Skolelinux on
 131 their machines, and as sitesummary is available in both distributions,
 132 it is trivial to get all of them to report to the same central
 133 collector.</p>

 180         <p>If Debian is to migrate to upstart on Linux, I expect some init.d
 181 scripts to migrate (some of) their operations to upstart job while
 182 keeping the init.d for hurd and kfreebsd.  The packages with such
 183 needs will need a way to get their init.d scripts to behave
 184 differently when used with sysvinit and with upstart.  Because of
 185 this, I had a look at the environment variables set when a init.d
 186 script is running under upstart, and when it is not.</p>
 187
 188 <p>With upstart, I notice these environment variables are set when a
 189 script is started from rcS.d/ (ignoring some irrelevant ones like
 190 COLUMNS):</p>
 191
 192 <blockquote><pre>
 193 DEFAULT_RUNLEVEL=2
 194 previous=N
 195 PREVLEVEL=
 196 RUNLEVEL=
 197 runlevel=S
 198 UPSTART_EVENTS=startup
 199 UPSTART_INSTANCE=
 200 UPSTART_JOB=rc-sysinit
 201 </pre></blockquote>
 202
 203 <p>With sysvinit, these environment variables are set for the same
 204 script.</p>
 205
 206 <blockquote><pre>
 207 INIT_VERSION=sysvinit-2.88
 208 previous=N
 209 PREVLEVEL=N
 210 RUNLEVEL=S
 211 runlevel=S
 212 </pre></blockquote>
 213
 214 <p>The RUNLEVEL and PREVLEVEL environment variables passed on from
 215 sysvinit are not set by upstart.  Not sure if it is intentional or not
 216 to not be compatible with sysvinit in this regard.</p>
 217
 218 <p>For scripts needing to behave differently when upstart is used,
 219 looking for the UPSTART_JOB environment variable seem to be a good
 220 choice.</p>

 241         <p>Det er merkelig hvordan myter om Skolelinux overlever.  En slik
 242 myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte
 243 tjenermaskiner.  I siste Computerworld Norge er
 244 <a href="http://www.idg.no/computerworld/article169432.ece">IT-sjef
 245 Viggo Billdal i Steinkjer intervjuet</a>, og forteller uten
 246 blygsel:</p>
 247
 248 <blockquote><p>Vi hadde Skolelinux, men det har vi sluttet med. Vi testet
 249 om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at
 250 Microsoft egentlig var totalt sett bedre egnet. Det var store
 251 driftskostnader med Skolelinux, blant annet på grunn av
 252 desentraliserte servere. Det var komplisert, så vi gikk vekk fra det
 253 og bruker nå bare Windows.</p></blockquote>
 254
 255 <p>En <a
 256 href="https://init.linpro.no/pipermail/skolelinux.no/bruker/2010-June/009101.html">rask
 257 sjekk</a> mot den norske brukerlista i Skolelinuxprosjektet forteller
 258 at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole
 259 i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen
 260 overkjørte skolen og krevde at de gikk over til Windows.  Et søk på
 261 nettet sendte meg til
 262 <a href="http://www.dn.no/multimedia/archive/00090/Dagens_it_nr__18_90826a.pdf">Dagens
 263 IT nr. 18 2005</a> hvor en kan lese på side 18:</p>

 265 <blockquote><p>Inge Tømmerås ved Røysing skole i Steinkjer kjører ennå
 266 Microsoft, men forteller at kompetanseutfordringen med Skolelinux ikke
 267 var så stor.   Jeg syntes Skolelinux var utrolig lett å drifte uten
 268 forkunnskaper. Men man må jo selvsagt ha tilgang på ekstern kompetanse
 269 til installasjoner og maskinvarefeil, sier Tømmerås.</p></blockquote>
 270
 271 <p>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
 272 over påstanden om at Skolelinux krever desentraliserte tjenere.
 273 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
 274 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
 275 Den er modellert på nettverks- og tjenerløsningen som brukes på
 276 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
 277 driftstjenester.  Dette er det heldigvis noen som har fått med seg, og
 278 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
 279 artikkelen.  Min venn og gamle kollega Sturle Sunde forteller der:
 280
 281 <blockquote>
 282 <p>I Flora kommune køyrer vi Skulelinux på skular med alt frå 15 til
 283 meir enn 500 elevar. Dei store skulane har eigen tenar, for det er
 284 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
 285 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
 286 avhengige av eksterne linjer som er trege eller dyre. Dei minste
 287 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
 288 noko problem. Småskulane klarar seg fint med 1 mbit-linje til ein
 289 sentral tenar eller tenaren på ein større skule.</p>
 290
 291 <p>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
 292 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
 293 programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har
 294 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
 295 millionen. Det trengst to kommandoar på den sentrale tenaren for å
 296 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
 297 problem med diskar som ryk heller, som var eit problem før fordi
 298 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
 299 nettet, so det er fullt mogleg å køyre slike på småskular med trege
 300 linjer mot tenaren på ein større skule.</p>
 301
 302 <p>Flora kommune har nesten 800 Linux-maskiner i sitt skulenett, og
 303 ein person som tek seg av drift av heile nettet, inkludert tenarar,
 304 klientar, operativsystem, programvare, heimekontorløysing og
 305 administrasjon av brukarar.</p>
 306
 307 <p>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
 308 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
 309 var der frå før, og som har komplisert installasjonen vår. Etter at
 310 oppsettet var gjort har løysinga vore stabil og kravd minimalt med
 311 arbeid.</p>
 312 </blockquote>
 313
 314 <p>Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux
 315 sentraldriftes med sentrale tjenere.  Det forteller meg at Steinkjers
 316 IT-sjef neppe bør skylde på Skolelinux-løsningen for sine 5 år gamle
 317 minner.</p>

 336       </div>
 337       <div class="body">
 338         <p>The last few days I have done some upgrade testing in Debian, to
 339 see if the upgrade from Lenny to Squeeze will go smoothly.  A few bugs
 340 have been discovered and reported in the process
 341 (<a href="http://bugs.debian.org/585410">#585410</a> in nagios3-cgi,
 342 <a href="http://bugs.debian.org/584879">#584879</a> already fixed in
 343 enscript and <a href="http://bugs.debian.org/584861">#584861</a> in
 344 kdebase-workspace-data), and to get a more regular testing going on, I
 345 am working on a script to automate the test.</p>
 346
 347 <p>The idea is to create a Lenny chroot and use tasksel to install a
 348 Gnome or KDE desktop installation inside the chroot before upgrading
 349 it.  To ensure no services are started in the chroot, a policy-rc.d
 350 script is inserted.  To make sure tasksel believe it is to install a
 351 desktop on a laptop, the tasksel tests are replaced in the chroot
 352 (only acceptable because this is a throw-away chroot).</p>
 353
 354 <p>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
 355 currently always fail because udev refuses to upgrade with the kernel
 356 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
 357 is created.  The bug report
 358 <a href="http://bugs.debian.org/566000">#566000</a> make me suspect
 359 this problem do not trigger in a chroot, but I touch the file anyway
 360 to make sure the upgrade go well.  Testing on virtual and real
 361 hardware have failed me because of udev so far, and creating this file
 362 do the trick in such settings anyway.  This is a
 363 <a href="http://www.linuxquestions.org/questions/debian-26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-804130/">known
 364 issue</a> and the current udev behaviour is intended by the udev
 365 maintainer because he lack the resources to rewrite udev to keep
 366 working with old kernels or something like that.  I really wish the
 367 udev upstream would keep udev backwards compatible, to avoid such
 368 upgrade problem, but given that they fail to do so, I guess
 369 documenting the way out of this mess is the best option we got for
 370 Debian Squeeze.</p>
 371
 372 <p>Anyway, back to the task at hand, testing upgrades.  This test
 373 script, which I call <tt>upgrade-test</tt> for now, is doing the
 374 trick:</p>

 436 <p>I suspect it would be useful to test upgrades with both apt-get and
 437 with aptitude, but I have not had time to look at how they behave
 438 differently so far.  I hope to get a cron job running to do the test
 439 regularly and post the result on the web.  The Gnome upgrade currently
 440 work, while the KDE upgrade fail because of the bug in
 441 kdebase-workspace-data</p>
 442
 443 <p>I am not quite sure what kind of extract from the huge upgrade logs
 444 (KDE 167 KiB, Gnome 516 KiB) it make sense to include in this blog
 445 post, so I will refrain from trying.  I can report that for Gnome,
 446 aptitude report 760 packages upgraded, 448 newly installed, 129 to
 447 remove and 1 not upgraded and 1024MB need to be downloaded while for
 448 KDE the same numbers are 702 packages upgraded, 507 newly installed,
 449 193 to remove and 0 not upgraded and 1117MB need to be downloaded</p>
 450
 451 <p>I am very happy to notice that the Gnome desktop + laptop upgrade
 452 is able to migrate to dependency based boot sequencing and parallel
 453 booting without a hitch.  Was unsure if there were still bugs with
 454 packages failing to clean up their obsolete init.d script during
 455 upgrades, and no such problem seem to affect the Gnome desktop+laptop
 456 packages.</p>

 477         <p>Veldig glad for å oppdage via
 478 <a href="http://yro.slashdot.org/story/10/06/11/1841256/Finland-To-Legalize-Use-of-Unsecured-Wi-Fi">Slashdot</a>
 479 at folk i Finland har forstått at åpne trådløsnett er et samfunnsgode.
 480 Jeg ser på åpne trådløsnett som et fellesgode på linje med retten til
 481 ferdsel i utmark og retten til å bevege seg i strandsonen.  Jeg har
 482 glede av åpne trådløsnett når jeg finner dem, og deler gladelig nett
 483 med andre så lenge de ikke forstyrrer min bruk av eget nett.
 484 Nettkapasiteten er sjelden en begrensning ved normal browsing og enkel
 485 SSH-innlogging (som er min vanligste nettbruk), og nett kan brukes til
 486 så mye positivt og nyttig (som nyhetslesing, sjekke været, kontakte
 487 slekt og venner, holde seg oppdatert om politiske saker, kontakte
 488 organisasjoner og politikere, etc), at det for meg er helt urimelig å
 489 blokkere dette for alle som ikke gjør en flue fortred.  De som mener
 490 at potensialet for misbruk er grunn nok til å hindre all den positive
 491 og lovlydige bruken av et åpent trådløsnett har jeg dermed ingen
 492 forståelse for.  En kan ikke la eksistensen av forbrytere styre hvordan
 493 samfunnet skal organiseres.  Da får en et kontrollsamfunn de færreste
 494 ønsker å leve i, og det at vi har et samfunn i Norge der tilliten til
 495 hverandre er høy gjør at samfunnet fungerer ganske godt.  Det bør vi
 496 anstrenge oss for å beholde.</p>

 519 of Debian upgrades</a> from Lenny to Squeeze continues, and I've
 520 finally made the upgrade logs available from
 521 <a href="http://people.skolelinux.org/pere/debian-upgrade-testing/">http://people.skolelinux.org/pere/debian-upgrade-testing/</a>.
 522 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
 523 apt and aptitude, and found their differences interesting.  This time
 524 I will only focus on their removal plans.</p>
 525
 526 <p>After installing a Gnome desktop and the laptop task, apt-get wants
 527 to remove 72 packages when dist-upgrading from Lenny to Squeeze.  The
 528 surprising part is that it want to remove xorg and all
 529 xserver-xorg-video* drivers.  Clearly not a good choice, but I am not
 530 sure why.  When asking aptitude to do the same, it want to remove 129
 531 packages, but most of them are library packages I suspect are no
 532 longer needed.  Both of them want to remove bluetooth packages, which
 533 I do not know.  Perhaps these bluetooth packages are obsolete?</p>
 534
 535 <p>For KDE, apt-get want to remove 82 packages, among them kdebase
 536 which seem like a bad idea and xorg the same way as with Gnome. Asking
 537 aptitude for the same, it wants to remove 192 packages, none which are
 538 too surprising.</p>
 539
 540 <p>I guess the removal of xorg during upgrades should be investigated
 541 and avoided, and perhaps others as well.  Here are the complete list
 542 of planned removals.  The complete logs is available from the URL
 543 above.  Note if you want to repeat these tests, that the upgrade test
 544 for kde+apt-get hung in the tasksel setup because of dpkg asking
 545 conffile questions.  No idea why.  I worked around it by using
 546 '<tt>echo >> /proc/<em>pidofdpkg</em>/fd/0</tt>' to tell dpkg to
 547 continue.</p>

 705         <p>For those of us caring about document exchange and
 706 interoperability, <a href="http://www.officeshots.org/">OfficeShots</a>
 707 is a great service.  It is to ODF documents what
 708 <a href="http://browsershots.org/">BrowserShots</a> is for web
 709 pages.</p>
 710
 711 <p>A while back, I was contacted by Knut Yrvin at the part of Nokia
 712 that used to be Trolltech, who wanted to help the OfficeShots project
 713 and wondered if the University of Oslo where I work would be
 714 interested in supporting the project.  I helped him to navigate his
 715 request to the right people at work, and his request was answered with
 716 a spot in the machine room with power and network connected, and Knut
 717 arranged funding for a machine to fill the spot.  The machine is
 718 administrated by the OfficeShots people, so I do not have daily
 719 contact with its progress, and thus from time to time check back to
 720 see how the project is doing.</p>
 721
 722 <p>Today I had a look, and was happy to see that the Dell box in our
 723 machine room now is the host for several virtual machines running as
 724 OfficeShots factories, and the project is able to render ODF documents
 725 in 17 different document processing implementation on Linux and
 726 Windows.  This is great.</p>

 750 sentralbanklovens paragraf 14 ved å nekte folk å betale med
 751 kontanter, og at flere butikker planlegger å følge deres eksempel.
 752 Jeg synes det er hårreisende hvis de slipper unna med et slikt
 753 soleklart lovbrudd, og lurer på hva slags muligheter jeg vil ha hvis
 754 jeg blir nektet å handle med kontanter.  Jeg handler i hovedsak med
 755 kontanter selv, da jeg anser det som en borgerrett å kunne handle
 756 anonymt uten at det blir registrert.  For meg er det et angrep på mitt
 757 personvern å nekte å ta imot kontant betaling.</p>

 759 <p><a href="http://www.lovdata.no/all/tl-19850524-028-003.html#14">Paragrafen
 760 i sentralbankloven</a> lyder:</p>
 761
 762 <blockquote>
 763 <p>§ 14. Tvungent betalingsmiddel</p>
 764
 765 <p>Bankens sedler og mynter er tvungent betalingsmiddel i Norge. Ingen
 766 er pliktig til i én betaling å ta imot mer enn femogtyve mynter av
 767 hver enhet.</p>
 768
 769 <p>Sterkt skadde sedler og mynter er ikke tvungent
 770 betalingsmiddel. Banken gir nærmere forskrifter om erstatning for
 771 bortkomne, brente eller skadde sedler og mynter.</p>
 772
 773 <p>Selv om en avtale inneholder klausul om betaling av en
 774 pengeforpliktelse i gullverdi, kan skyldneren frigjøre seg med tvungne
 775 betalingsmidler uten hensyn til denne klausul.</p>
 776 </blockquote>
 777
 778 <p>Det er med bakgrunn i denne lovet ikke tillatt å nekte å ta imot
 779 kontakt betaling.  Det er en lov jeg har sans for, og som jeg mener må
 780 håndheves strengt.</p>

 801         <p>A few times I have had the need to simulate the way tasksel
 802 installs packages during the normal debian-installer run.  Until now,
 803 I have ended up letting tasksel do the work, with the annoying problem
 804 of not getting any feedback at all when something fails (like a
 805 conffile question from dpkg or a download that fails), using code like
 806 this:
 807
 808 <blockquote><pre>
 809 export DEBIAN_FRONTEND=noninteractive
 810 tasksel --new-install
 811 </pre></blockquote>
 812
 813 This would invoke tasksel, let its automatic task selection pick the
 814 tasks to install, and continue to install the requested tasks without
 815 any output what so ever.
 816
 817 Recently I revisited this problem while working on the automatic
 818 package upgrade testing, because tasksel would some times hang without
 819 any useful feedback, and I want to see what is going on when it
 820 happen.  Then it occured to me, I can parse the output from tasksel
 821 when asked to run in test mode, and use that aptitude command line
 822 printed by tasksel then to simulate the tasksel run.  I ended up using
 823 code like this:
 824
 825 <blockquote><pre>
 826 export DEBIAN_FRONTEND=noninteractive
 827 cmd="$(in_target tasksel -t --new-install | sed 's/debconf-apt-progress -- //')"
 828 $cmd
 829 </pre></blockquote>
 830
 831 <p>The content of $cmd is typically something like "<tt>aptitude -q
 832 --without-recommends -o APT::Install-Recommends=no -y install
 833 ~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired
 834 ~pimportant</tt>", which will install the gnome desktop task, the
 835 laptop task and all packages with priority standard , required and
 836 important, just like tasksel would have done it during
 837 installation.</p>
 838
 839 <p>A better approach is probably to extend tasksel to be able to
 840 install packages without using debconf-apt-progress, for use cases
 841 like this.</p>

 862         <p>A while back, I
 863 <a href="http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html">complained
 864 about the fact</a> that it is not possible with the provided schemas
 865 for storing DNS and DHCP information in LDAP to combine the two sets
 866 of information into one LDAP object representing a computer.</p>
 867
 868 <p>In the mean time, I discovered that a simple fix would be to make
 869 the dhcpHost object class auxiliary, to allow it to be combined with
 870 the dNSDomain object class, and thus forming one object for one
 871 computer when storing both DHCP and DNS information in LDAP.</p>
 872
 873 <p>If I understand this correctly, it is not safe to do this change
 874 without also changing the assigned number for the object class, and I
 875 do not know enough about LDAP schema design to do that properly for
 876 Debian Edu.</p>
 877
 878 <p>Anyway, for future reference, this is how I believe we could change
 879 the
 880 <a href="http://tools.ietf.org/html/draft-ietf-dhc-ldap-schema-00">DHCP
 881 schema</a> to solve at least part of the problem with the LDAP schemas
 882 available today from IETF.</p>

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

 924         <p>The last few days I have been looking into the status of the LDAP
 925 directory in Debian Edu, and in the process I started to miss a GUI
 926 tool to browse the LDAP tree.  The only one I was able to find in
 927 Debian/Squeeze and Lenny is
 928 <a href="http://luma.sourceforge.net/">LUMA</a>, which has proved to
 929 be a great tool to get a overview of the current LDAP directory
 930 populated by default in Skolelinux.  Thanks to it, I have been able to
 931 find empty and obsolete subtrees, misplaced objects and duplicate
 932 objects.  It will be installed by default in Debian/Squeeze.  If you
 933 are working with LDAP, give it a go. :)</p>
 934
 935 <p>I did notice one problem with it I have not had time to report to
 936 the BTS yet.  There is no .desktop file in the package, so the tool do
 937 not show up in the Gnome and KDE menus, but only deep down in in the
 938 Debian submenu in KDE.  I hope that can be fixed before Squeeze is
 939 released.</p>
 940
 941 <p>I have not yet been able to get it to modify the tree yet.  I would
 942 like to move objects and remove subtrees directly in the GUI, but have
 943 not found a way to do that with LUMA yet.  So in the mean time, I use
 944 <a href="http://www.lichteblau.com/ldapvi/">ldapvi</a> for that.</p>
 945
 946 <p>If you have tips on other GUI tools for LDAP that might be useful
 947 in Debian Edu, please contact us on debian-edu@lists.debian.org.</p>
 948
 949 <p>Update 2010-06-29: Ross Reedstrom tipped us about the
 950 <a href="http://packages.qa.debian.org/g/gq.html">gq</a> package as a
 951 useful GUI alternative.  It seem like a good tool, but is unmaintained
 952 in Debian and got a RC bug keeping it out of Squeeze.  Unless that
 953 changes, it will not be an option for Debian Edu based on Squeeze.</p>
