  45       <div class="date">18th February 2012</div>
  46       <div class="body"><p>I serien med intervjuer av folk i
  47 <a href="http://www.skolelinux.org/">Skolelinux</a>-miljøet, får vi nå
  48 høre fra et nyvalgt medlem i foreningen
  49 <a href="http://www.friprogramvareiskolen.no/">Fri programvare i
  50 Skolen</a>.</p>
  51
  52 <p><strong>Hvem er du, og hva driver du med til daglig?</strong></p>
  53
  54 <p>Jeg heter Olav Dahlum, og er frilans oversetter, tester,
  55 prosjektleder og bruker av fri og åpen programvare som
  56 LibreOffice. Jeg er også et av styremedlemmene i FRISK.</p>
  57
  58 <p><strong>Hvordan kom du i kontakt med Skolelinux-prosjektet?</strong></p>
  59
  60 <p>Jeg kom i kontakt med prosjektet i 2009, da jeg ble ansatt i
  61 stiftelsen Åpne kontorprogram på norsk for å oversette og teste den
  62 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært
  63 koordinert sammen med Skolelinux, og mange av de samme menneskene er
  64 involvert, så på den måten ble jeg en del av den utvidede
  65 familien.</p>
  66
  67 <p><strong>Hva er fordelene med Skolelinux slik du ser det?</strong></p>
  68
  69 <p>Skolelinux handler i likhet med utdanningssektoren om å dele
  70 kunnskap med andre, og det er dette som er hovedstyrken til
  71 prosjektet.  Selv om Skolelinux hovedsaklig er involvert i utvikling
  72 av programvare, er det også et sted der man kan utfolde seg uavhengig
  73 av bakgrunn og ferdigheter.</p>
  74
  75 <p><strong>Hva er ulempene med Skolelinux slik du ser det?</strong></p>
  76
  77 <p>Liten utbredelse og manglende støtte fra leverandører som leverer
  78 pedagogisk programvare til skolebruk.  Kunne kanskje hatt flere
  79 verktøy som letter administrasjonen ytterligere, slik at også mindre
  80 erfarne databrukere kan utføre lett vedlikehold og rutinejobber.</p>
  81
  82 <p><strong>Hvilken fri programvare bruker du til daglig?</strong></p>
  83
  84 <p>Jeg er nesten forpliktet til å si at jeg bruker LibreOffice... Jeg
  85 bruker forøvrig frie og åpne operativsystemer basert på
  86 operativsystemkjernen Linux, for tiden openSUSE 12,1 med KDE4.  Men
  87 hvis jeg skal dra fram noen flere eksempler så er nok Mozilla Firefox
  88 og Thunderbird to av de jeg bruker mest. I tillegg er jeg en flittig
  89 bruker av OpenSSH, Irssi, Midnight Commander, Git, Subversion,
  90 Translation Toolkit og Super Maryo Chronicles (litt gøy skal man ha,
  91 og med to håndkontroller liggende er det ikke til å unngå).</p>
  92
  93 <p><strong>Hvilken strategi tror du er den rette å bruke for å få
  94 skoler til å ta i bruk fri programvare?</strong></p>
  95
  96 <p>Vi må få leverandører av pedagogisk programvare med på laget, men
  97 også utvikle vår egen tilpasset det norske markedet.  Det er også
  98 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
  99 gjennom studentprosjekter der elevene selv er med å utforme
 100 programvare direkte eller indirekte gjennom aktive bidrag.  Dette gjør
 101 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
 102 til å velge sin egen løsning vil kanskje stimulere interessen for
 103 framtidig deltakelse i bransjen.  Vi som driver med fri og åpen
 104 programvare ønsker oss ikke rene konsumenter, men tenkende og
 105 selvstendige individer som kan være med å skape sin egen fremtid.</p>

 119       <div class="date">14th February 2012</div>
 120       <div class="body"><p>Once in a while my home server have disk problems.  Thanks to Linux
 121 Software RAID, I have not lost data yet (but
 122 <a href="http://comments.gmane.org/gmane.linux.raid/34532">I was
 123 close</a> this summer :).  But once a disk is starting to behave
 124 funny, a practical problem present itself.  How to get from the Linux
 125 device name (like /dev/sdd) to something that can be used to identify
 126 the disk when the computer is turned off?  In my case I have SATA
 127 disks with a unique ID printed on the label.  All I need is a way to
 128 figure out how to query the disk to get the ID out.</p>
 129
 130 <p>After fumbling a bit, I
 131 <a href="http://www.cyberciti.biz/faq/linux-getting-scsi-ide-harddisk-information/">found
 132 that hdparm -I</a> will report the disk serial number, which is
 133 printed on the disk label.  The following (almost) one-liner can be
 134 used to look up the ID of all the failed disks:</p>
 135
 136 <blockquote><pre>
 137 for d in $(cat /proc/mdstat |grep '(F)'|tr ' ' "\n"|grep '(F)'|cut -d\[ -f1|sort -u);
 138 do
 139     printf "Failed disk $d: "
 140     hdparm -I /dev/$d |grep 'Serial Num'
 141 done
 142 </blockquote></pre>
 143
 144 <p>Putting it here to make sure I do not have to search for it the
 145 next time, and in case other find it useful.</p>
 146
 147 <p>At the moment I have two failing disk. :(</p>
 148
 149 <blockquote><pre>
 150 Failed disk sdd1:       Serial Number:      WD-WCASJ1860823
 151 Failed disk sdd2:       Serial Number:      WD-WCASJ1860823
 152 Failed disk sde2:       Serial Number:      WD-WCASJ1840589
 153 </blockquote></pre>
 154
 155 <p>The last time I had failing disks, I added the serial number on
 156 labels I printed and stuck on the short sides of each disk, to be able
 157 to figure out which disk to take out of the box without having to
 158 remove each disk to look at the physical vendor label.  The vendor
 159 label is at the top of the disk, which is hidden when the disks are
 160 mounted inside my box.</p>
 161
 162 <p>I really wish the check_linux_raid Nagios plugin for checking Linux
 163 Software RAID in the
 164 <a href="http://packages.qa.debian.org/n/nagios-plugins.html">nagios-plugins-standard</a>
 165 debian package would look up this value automatically, as it would
 166 make the plugin a lot more useful when my disks fail.  At the moment
 167 it only report a failure when there are no more spares left (it really
 168 should warn as soon as a disk is failing), and it do not tell me which
 169 disk(s) is failing when the RAID is running short on disks.</p>

 183       <div class="date">13th February 2012</div>
 184       <div class="body"><p>New in the Squeeze version of
 185 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> is the
 186 ability for clients to automatically configure their proxy settings
 187 based on their environment.  We want all systems on the client to use
 188 the WPAD based proxy definition fetched from <tt>http://wpad/wpad.dat</tt>, to
 189 allow sites to control the proxy setting from a central place and make
 190 sure clients do not have hard coded proxy settings.  The schools can
 191 change the global proxy setting by editing
 192 <tt>tjener:/etc/debian-edu/www/wpad.dat</tt> and the change propagate
 193 to all Debian Edu clients in the network.</p>
 194
 195 <p>The problem is that some systems do not understand the WPAD system.
 196 In other words, how do one get from a WPAD file like this (this is a
 197 simple one, they can run arbitrary code):</p>
 198
 199 <blockquote><pre>
 200 function FindProxyForURL(url, host)
 201 {
 202    if (!isResolvable(host) ||
 203        isPlainHostName(host) ||
 204        dnsDomainIs(host, ".intern"))
 205       return "DIRECT";
 206    else
 207       return "PROXY webcache:3128; DIRECT";
 208 }
 209 </pre></blockquote>
 210
 211 <p>to a proxy setting in the process environment looking like this:</p>
 212
 213 <blockquote><pre>
 214 http_proxy=http://webcache:3128/
 215 ftp_proxy=http://webcache:3128/
 216 </pre></blockquote>
 217
 218 <p>To do this conversion I developed a perl script that will execute
 219 the javascript fragment in the WPAD file and return the proxy that
 220 would be used for
 221 <tt><a href="http://www.debian.org/">http://www.debian.org/</a></tt>,
 222 and insert this extracted proxy URL in <tt>/etc/environment</tt> and
 223 <tt>/etc/apt/apt.conf</tt>.  The perl script wpad-extract work just
 224 fine in Squeeze, but in Wheezy the library it need to run the
 225 javascript code is <a href="http://bugs.debian.org/631045">no longer
 226 able to build</a> because the C library it depended on is now a C++
 227 library.  I hope someone find a solution to that problem before Wheezy
 228 is frozen.  An alternative would be for us to rewrite wpad-extract to
 229 use some other javascript library currently working in Wheezy, but no
 230 known alternative is known at the moment.</p>
 231
 232 <p>This automatic proxy system allow the roaming workstation (aka
 233 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
 234 is connected to the backbone network in a Debian Edu setup, and to
 235 automatically use any proxy present and announced using the WPAD
 236 feature when it is connected to other networks.  And if no proxy is
 237 announced, direct connections will be used instead.</p>
 238
 239 <p>Silently using a proxy announced on the network might be a privacy
 240 or security problem.  But those controlling DHCP and DNS on a network
 241 could just as easily set up a transparent proxy, and force all HTTP
 242 and FTP connections to use a proxy anyway, so I consider that
 243 distinction to be academic.  If you are afraid of using the wrong
 244 proxy, you should avoid connecting to the network in question in the
 245 first place.  In Debian Edu, the proxy setup is updated using dhcp and
 246 ifupdown hooks, to make sure the configuration is updated every time
 247 the network setup changes.</p>
 248
 249 <p>The WPAD system is documented in a
 250 <a href="http://tools.ietf.org/html/draft-ietf-wrec-wpad-01">IETF
 251 draft</a> and a
 252 <a href="http://en.wikipedia.org/wiki/Web_Proxy_Autodiscovery_Protocol">Wikipedia
 253 page</a> for those that want to learn more.</p>

 267       <div class="date"> 7th February 2012</div>
 268       <div class="body"><p>I serien med intervjuer av folk i
 269 <a href="http://www.skolelinux.org/">Skolelinux</a>-miljøet har jeg
 270 fått en av oversetterne som har vært med siden starten i tale.</p>
 271
 272 <p><strong>Hvem er du, og hva driver du med til daglig?</strong></p>
 273
 274 <p>Jeg heter Axel Bojer og er datalærer, tysklærer, oversetter med
 275 mere.</p>
 276
 277 <p><strong>Hvordan kom du i kontakt med Skolelinux-prosjektet?</strong></p>
 278
 279 <p>Tror jeg så en annonsering på nettet i slutten av 2001 og ville
 280 være med som oversetter.  Jeg kom med på en utviklersamling og
 281 prosjektet var da helt i starten.  Det var spennende å være med mens
 282 prosjektet vokste til og utviklet seg.</p>
 283
 284 <p>Jeg har «alltid» vært språkinteressert og hadde nettopp startet med
 285 Linux og tror jeg tenkte det passet å bidra.  Var også glad for å få
 286 en Debian-distribusjon, og ville gjerne bruke den selv.  Til å begynne
 287 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at
 288 det ikke var noen mulighet for å bruke den som enkeltstående i lang
 289 tid, så gikk jeg etterhvert over til Kubuntu</p>
 290
 291 <p><strong>Hva er fordelene med Skolelinux slik du ser det?</strong></p>
 292
 293 <p>Løsningen er forholdsvis lett å sette opp, gratis, fri programvare
 294 og gjør det mulig å gjenbruke eldre maskiner.  Det fine med Debian er
 295 at det er stabilt og har en veldig stor mengde programmer. Jeg liker
 296 også apt.  :-) Jeg liker også friheten ved Linux og muligheten til å
 297 delta og forme sin egen datahverdag.</p>
 298
 299 <p><strong>Hva er ulempene med Skolelinux slik du ser det?</strong></p>
 300
 301 <p>Skolelinux er for lite kjent og for sent ute med å gi ut nye
 302 versjoner.</p>
 303
 304 <p>Da jeg selv i hovedsak bruker Kubuntu, så kan jeg egentlig ikke
 305 svare så detaljert rundt ulempene med Skolelinux.  Hovedårsaken til at
 306 jeg bruker Kubuntu er nok at da vi begynte med det mener jeg det ikke
 307 var noen annen løsning.  «Vandrende arbeidsstasjon» mener jeg ikke
 308 fantes da.  Dessuten ville jeg ha siste versjon, da den KDE-versjonen
 309 som var i Skolelinux den gangen var en god del enklere (tror det var
 310 KDE 2) var dårligere i mine øyne enn versjon 3.</p>
 311
 312 <p><strong>Hvilken fri programvare bruker du til daglig?</strong></p>
 313
 314 <p>Jeg bruker blant annet Kubuntu, LibreOffice, Thunderbird, Firefox,
 315 Kate, <a href="http://comix.sourceforge.net/">Comix</a> og Konsole.  Og
 316 en hel haug andre ved behov :-)</p>
 317
 318 <p>Har oversatt Comix selv, men det er jo ikke skjedd noe med Comix
 319 siden 2009, så den er det nok bare jeg som har.  Om andre vil ha den
 320 gir jeg den gjerne videre.  Ser at noen har startet på
 321 <a href="http://mcomix.sourceforge.net/">MComix</a> siden jeg så på så
 322 på dette sist, så nå er jeg igang med å teste og oversette den
 323 også.</p>
 324
 325 <p><strong>Hvilken strategi tror du er den rette å bruke for å få
 326 skoler til å ta i bruk fri programvare?</strong></p>
 327
 328 <p>Det viktigste er å forankre beslutningen i kollegiet og med de som
 329 er ansvarlige for å vedlikeholde og bruke datamaskinene.  Flest mulig
 330 bør være med på å holde det (sosialt) vedlike, kjenne og støtte
 331 prinsippene. Som enkeltmannsprosjekt blir det lett veldig sårbart,
 332 særlig når (Skole)linux ennå i stor grad er en motkultur og ikke noe
 333 en stor nok andel av beslutningstakere, brukere osv kjenner til og
 334 bruker.</p>
 335
 336 <p>Jeg tror det viktigste er å fortsette å holde fri programvare godt,
 337 oppdatert, minimere antall feil, ha en god kontakt med brukerne og
 338 attraktivt og spennende programmer. Beholde alt som er bra og ha det
 339 tilgjengelig samtidig som man tilbyr det nyeste og rareste for de som
 340 vil ha det.</p>

 354       <div class="date"> 5th February 2012</div>
 355       <div class="body"><p>Since the Lenny version of
 356 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, a
 357 feature to save power have been included.  It is as simple as it is
 358 practical: Shut down unused clients at night, and turn them on again
 359 in the morning.  This is done using the
 360 <a href="http://packages.qa.debian.org/s/shutdown-at-night.html">shutdown-at-night</a> Debian package.</p>
 361
 362 <p>To enable this feature on a client, the machine need to be added to
 363 the netgroup shutdown-at-night-hosts.  For Debian Edu, this is done in
 364 LDAP, and once this is in place, the machine in question will check
 365 every hour from 16:00 until 06:00 to see if the machine is unused, and
 366 shut it down if it is.  If the hardware in question is supported by
 367 the
 368 <a href="http://packages.qa.debian.org/n/nvram-wakeup.html">nvram-wakeup</a>
 369 package, the BIOS is told to turn the machine back on around 07:00 +-
 370 10 minutes.  If this isn't working, one can configure wake-on-lan to
 371 try to turn on the client.  The wake-on-lan option is only documented
 372 and not enabled by default in Debian Edu.</p>
 373
 374 <p>It is important to not turn all machines on at once, as this can
 375 blow a fuse if several computers are connected to the same fuse like
 376 the common setup for a classroom.  The nvram-wakeup method only work
 377 for machines with a functioning hardware/BIOS clock.  I've seen old
 378 machines where the BIOS battery were dead and the hardware clock were
 379 starting from 0 (or was it 1990?) every boot.  If you have one of
 380 those, you have to turn on the computer manually.</p>
 381
 382 <p>The shutdown-at-night package is completely self contained, and can
 383 also be used outside the Debian Edu environment.  For those without a
 384 central LDAP server with netgroups, one can instead touch the file
 385 <tt>/etc/shutdown-at-night/shutdown-at-night</tt> to enable it.
 386 Perhaps you too can use it to save some power?</p>

 402 publish the third beta version of
 403 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> based
 404 on Squeeze.  If you want to test a LDAP backed Kerberos server with
 405 out of the box PXE configuration for running diskless machines and
 406 installing new machines, check it out.  If you need a software
 407 solution for your school, check it out too.  The full announcement is
 408 <a href="http://lists.debian.org/debian-edu-announce/2012/02/msg00000.html">available</a>
 409 on the project announcement list.</p>
 410
 411 <p>I am very happy to report these changes and improvements since
 412 beta2 (there are more, see announcement for full list):</p>
 413
 414 <ul>
 415
 416 <li>It is now possible to change the pre-configured IP subnet from
 417   10.0.0.0/8 to something else by using the subnet-change tool after
 418   the installation.</li>
 419
 420 <li>Too full partitions are now automatically extended on the Main
 421   Server, based on the rules specified in /etc/fsautoresizetab.</li>
 422
 423 <li>The CUPS queues are now automatically flushed every night, and all
 424   disabled queues are restarted every hour.  This should cut down on
 425   the amount of manual administration needed for printers.</li>
 426
 427 <li>The set of initial users have been changed.  Now a personal user
 428   for the local system administrator is created during installation
 429   instead of the previously created localadmin and super-admin users,
 430   and this user is granted administrative privileges using group
 431   membership.  This reduces the number of passwords one need to keep
 432   up to date on the system.</li>
 433
 434 </ul>
 435
 436 <p>The new main server seem to work so well that I am testing it as my
 437 private DNS/LDAP/Kerberos/PXE/LTSP server at home.  I will use it look
 438 for issues we could fix to polish Debian Edu even further before the
 439 final Squeeze release is published.</p>
 440
 441 <p>Next weekend the project organise a
 442 <a href="http://lists.debian.org/debian-edu-announce/2012/01/msg00001.html">developer
 443 gathering</a> in Oslo.  We will continue the work on the Squeeze
 444 version, and start initial planning for the Wheezy version.  Perhaps I
 445 will see you there?</p>

 459       <div class="date">27th January 2012</div>
 460       <div class="body"><p>With some computer hardware, one need non-free firmware blobs.
 461 This is the sad fact of todays computers.  In the next version of
 462 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> based
 463 on Squeeze, we provide several scripts and modifications to make
 464 firmware blobs easier to handle.  The common use case I run into is a
 465 laptop with a wireless network card requiring non-free firmware to
 466 work, but there are other use cases as well.</p>
 467
 468 <p>First and foremost, Debian Edu provide ISO images for DVD and CD
 469 with all firmware packages in the Debian sections main and non-free
 470 included, to ensure debian-installer find and can install all of them
 471 during installation.  This take care firmware for network devices used
 472 by the installer when installing from from local media.  But for
 473 example multimedia devices are not activated in the installer and are
 474 not taken care of by this.</p>
 475
 476 <p>For non-network devices, we provide the script
 477 <tt>/usr/share/debian-edu-config/tools/auto-addfirmware</tt> which
 478 search through the <tt>dmesg</tt> output for drivers requesting extra
 479 firmware.  The firmware file name is looked up in the Contents-ARCH.gz
 480 file available in the package repository, and the packages providing
 481 the requested firmware file(s) is installed.  I have proposed to do
 482 something similar in debian-installer (BTS report
 483 <a href="http://bugs.debian.org/655507">#655507</a>), to allow PXE
 484 installs of Debian to handle firmware installation better.  Run the
 485 script as root from the command line to fetch and install the needed
 486 firmware packages.</p>
 487
 488 <p>Debian Edu provide PXE installation of Debian out of the box, and
 489 because some machines need firmware to get their network cards
 490 working, the installation initrd some times need extra firmware
 491 included to be able to install at all.  To fill the PXE installation
 492 initrd with extra firmware, the
 493 <tt>/usr/share/debian-edu-config/tools/pxe-addfirmware</tt> script is
 494 provided.  Again, just run it as root on the command line to fill the
 495 PXE initrd with firmware packages.</p>
 496
 497 <p>Last, some LTSP clients might also need firmware to get their
 498 network cards working.  For this,
 499 <tt>/usr/share/debian-edu-config/tools/ltsp-addfirmware</tt> is
 500 provided to update the LTSP initrd with firmware blobs.  It is used
 501 the same way as the other firmware related tools.</p>
 502
 503 <p>At the moment, we do not run any of these during installation.  We
 504 do not know if this is acceptable for the local administrator to use
 505 non-free software, and it is their choice.</p>
 506
 507 <p>We plan to release beta3 this weekend.  You might want to give it a
 508 try.</p>

 526
 527 <p>Som en kan se der er det noen oversettelser som mangler.  Det hadde
 528 vært hyggelig hvis alle tekstene som vises i Skolelinux-installasjonen
 529 ble oversatt til nordsamisk, men for å få det til må noen som forstår
 530 språket melde seg til dyst.  Det er mangel på nordsamiske oversettere
 531 av fri programvare.  Hvis noen starter raskt, så bør en rekke å
 532 fullføre Wheezy-utgaven før den gis ut. :)</p>
 533
 534 <p>Se <a href="http://d-i.debian.org/l10n-stats/">oversetterstatistikk for
 535 debian installer</a> for detaljert status.  Jeg har tipset
 536 <a href="https://lister.ping.uio.no/mailman/listinfo/i18n-sme">epostlisten for samiskoversettelser</a>,
 537 men det har vært veldig liten aktivitet der de siste årene.</p>

 574       <div class="date">25th January 2012</div>
 575       <div class="body"><p>The next version of <a href="http://www.skolelinux.org/">Debian Edu
 576 / Skolelinux</a> will include a new tool
 577 <tt>sitesummary2ldapdhcp</tt>, which can be used to quickly set up all
 578 the computers in a school without much manual labour.  Here is a short
 579 summary on how to use it to set up a new school.</p>
 580
 581 <p>First, install a combined Main Server and Thin Client Server as the
 582 central server in the network.  Next, PXE boot all the client machines
 583 as thin clients and wait 5 minutes after the last client booted to
 584 allow the clients to report their existence to the central server.  When
 585 this is done, log on to the central server and run
 586 <tt>sitesummary2ldapdhcp -a</tt> in the <tt>konsole</tt> to use the
 587 collected information to generate system objects in LDAP.  The output
 588 will look similar to this:</p>
 589
 590 <p><blockquote><pre>
 591 % sitesummary2ldapdhcp -a
 592 info: Updating machine tjener.intern [10.0.2.2] id ether-00:01:02:03:04:05.
 593 info: Create GOsa machine for auto-mac-00-01-02-03-04-06 [10.0.16.20] id ether-00:01:02:03:04:06.
 594
 595 Enter password if you want to activate these changes, and ^c to abort.
 596
 597 Connecting to LDAP as cn=admin,ou=ldap-access,dc=skole,dc=skolelinux,dc=no
 598 enter password: *******
 599 %
 600 </pre></blockquote></p>
 601
 602 <p>After providing the LDAP administrative password (the same as the
 603 root password set during installation), the LDAP database will be
 604 populated with system objects for each PXE booted machine with
 605 automatically generated names.  The final step to set up the school is
 606 then to log into <a href="https://oss.gonicus.de/labs/gosa/">GOsa</a>,
 607 the web based user, group and system administration system to change
 608 system names, add systems to the correct host groups and finally
 609 enable DHCP and DNS for the systems.  All clients that should be used
 610 as diskless workstations should be added to the workstation-hosts
 611 group.  After this is done, all computers can be booted again via PXE
 612 and get their assigned names and group based configuration
 613 automatically.</p>
 614
 615 <p>We plan to release beta3 with the updated version of this feature
 616 enabled this weekend.  You might want to give it a try.</p>
 617
 618 <p>Update 2012-01-28: When calling sitesummary2ldapdhcp to add new
 619 hosts, one need to add the option -a.  I forgot to mention this in my
 620 original text, and have added it to the text now.</p>
