  14                 <description>&lt;p&gt;With some computer hardware, one need non-free firmware blobs.
  15 This is the sad fact of todays computers.  In the next version of
  16 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; based
  17 on Squeeze, we provide several scripts and modifications to make
  18 firmware blobs easier to handle.  The common use case I run into is a
  19 laptop with a wireless network card requiring non-free firmware to
  20 work, but there are other use cases as well.&lt;/p&gt;
  21
  22 &lt;p&gt;First and foremost, Debian Edu provide ISO images for DVD and CD
  23 with all firmware packages in the Debian sections main and non-free
  24 included, to ensure debian-installer find and can install all of them
  25 during installation.  This take care firmware for network devices used
  26 by the installer when installing from from local media.  But for
  27 example multimedia devices are not activated in the installer and are
  28 not taken care of by this.&lt;/p&gt;
  29
  30 &lt;p&gt;For non-network devices, we provide the script
  31 &lt;tt&gt;/usr/share/debian-edu-config/tools/auto-addfirmware&lt;/tt&gt; which
  32 search through the &lt;tt&gt;dmesg&lt;/tt&gt; output for drivers requesting extra
  33 firmware.  The firmware file name is looked up in the Contents-ARCH.gz
  34 file available in the package repository, and the packages providing
  35 the requested firmware file(s) is installed.  I have proposed to do
  36 something similar in debian-installer (BTS report
  37 &lt;a href=&quot;http://bugs.debian.org/655507&quot;&gt;#655507&lt;/a&gt;), to allow PXE
  38 installs of Debian to handle firmware installation better.  Run the
  39 script as root from the command line to fetch and install the needed
  40 firmware packages.&lt;/p&gt;
  41
  42 &lt;p&gt;Debian Edu provide PXE installation of Debian out of the box, and
  43 because some machines need firmware to get their network cards
  44 working, the installation initrd some times need extra firmware
  45 included to be able to install at all.  To fill the PXE installation
  46 initrd with extra firmware, the
  47 &lt;tt&gt;/usr/share/debian-edu-config/tools/pxe-addfirmware&lt;/tt&gt; script is
  48 provided.  Again, just run it as root on the command line to fill the
  49 PXE initrd with firmware packages.&lt;/p&gt;
  50
  51 &lt;p&gt;Last, some LTSP clients might also need firmware to get their
  52 network cards working.  For this,
  53 &lt;tt&gt;/usr/share/debian-edu-config/tools/ltsp-addfirmware&lt;/tt&gt; is
  54 provided to update the LTSP initrd with firmware blobs.  It is used
  55 the same way as the other firmware related tools.&lt;/p&gt;
  56
  57 &lt;p&gt;At the moment, we do not run any of these during installation.  We
  58 do not know if this is acceptable for the local administrator to use
  59 non-free software, and it is their choice.&lt;/p&gt;
  60
  61 &lt;p&gt;We plan to release beta3 this weekend.  You might want to give it a
  62 try.&lt;/p&gt;

  70                 <pubDate>Thu, 26 Jan 2012 20:00:00 +0100</pubDate>
  71                 <description>&lt;p&gt;For morro skyld har jeg gjennomført en nordsamisk installasjon for
  72 neste utgave av &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;
  73 (Squeeze) og knipset skjermbilder av resultatet.&lt;/p&gt;
  74
  75 &lt;p&gt;Som en kan se der er det noen oversettelser som mangler.  Det hadde
  76 vært hyggelig hvis alle tekstene som vises i Skolelinux-installasjonen
  77 ble oversatt til nordsamisk, men for å få det til må noen som forstår
  78 språket melde seg til dyst.  Det er mangel på nordsamiske oversettere
  79 av fri programvare.  Hvis noen starter raskt, så bør en rekke å
  80 fullføre Wheezy-utgaven før den gis ut. :)&lt;/p&gt;
  81
  82 &lt;p&gt;Se &lt;a href=&quot;http://d-i.debian.org/l10n-stats/&quot;&gt;oversetterstatistikk for
  83 debian installer&lt;/a&gt; for detaljert status.  Jeg har tipset
  84 &lt;a href=&quot;https://lister.ping.uio.no/mailman/listinfo/i18n-sme&quot;&gt;epostlisten for samiskoversettelser&lt;/a&gt;,
  85 men det har vært veldig liten aktivitet der de siste årene.&lt;/p&gt;

 114                 <link>https://www.hungry.com/~pere/blog/Setting_up_a_new_school_with_Debian_Edu_Squeeze.html</link>
 115                 <guid isPermaLink="true">https://www.hungry.com/~pere/blog/Setting_up_a_new_school_with_Debian_Edu_Squeeze.html</guid>
 116                 <pubDate>Wed, 25 Jan 2012 21:00:00 +0100</pubDate>
 117                 <description>&lt;p&gt;The next version of &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu
 118 / Skolelinux&lt;/a&gt; will include a new tool
 119 &lt;tt&gt;sitesummary2ldapdhcp&lt;/tt&gt;, which can be used to quickly set up all
 120 the computers in a school without much manual labour.  Here is a short
 121 summary on how to use it to set up a new school.&lt;/p&gt;
 122
 123 &lt;p&gt;First, install a combined Main Server and Thin Client Server as the
 124 central server in the network.  Next, PXE boot all the client machines
 125 as thin clients and wait 5 minutes after the last client booted to
 126 allow the clients to report their existence to the central server.  When
 127 this is done, log on to the central server and run
 128 &lt;tt&gt;sitesummary2ldapdhcp -a&lt;/tt&gt; in the &lt;tt&gt;konsole&lt;/tt&gt; to use the
 129 collected information to generate system objects in LDAP.  The output
 130 will look similar to this:&lt;/p&gt;
 131
 132 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 133 % sitesummary2ldapdhcp -a
 134 info: Updating machine tjener.intern [10.0.2.2] id ether-00:01:02:03:04:05.
 135 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.
 136
 137 Enter password if you want to activate these changes, and ^c to abort.
 138
 139 Connecting to LDAP as cn=admin,ou=ldap-access,dc=skole,dc=skolelinux,dc=no
 140 enter password: *******
 141 %
 142 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 143
 144 &lt;p&gt;After providing the LDAP administrative password (the same as the
 145 root password set during installation), the LDAP database will be
 146 populated with system objects for each PXE booted machine with
 147 automatically generated names.  The final step to set up the school is
 148 then to log into &lt;a href=&quot;https://oss.gonicus.de/labs/gosa/&quot;&gt;GOsa&lt;/a&gt;,
 149 the web based user, group and system administration system to change
 150 system names, add systems to the correct host groups and finally
 151 enable DHCP and DNS for the systems.  All clients that should be used
 152 as diskless workstations should be added to the workstation-hosts
 153 group.  After this is done, all computers can be booted again via PXE
 154 and get their assigned names and group based configuration
 155 automatically.&lt;/p&gt;
 156
 157 &lt;p&gt;We plan to release beta3 with the updated version of this feature
 158 enabled this weekend.  You might want to give it a try.&lt;/p&gt;
 159
 160 &lt;p&gt;Update 2012-01-28: When calling sitesummary2ldapdhcp to add new
 161 hosts, one need to add the option -a.  I forgot to mention this in my
 162 original text, and have added it to the text now.&lt;/p&gt;

 169                 <guid isPermaLink="true">https://www.hungry.com/~pere/blog/Skolelinux_intervju__Paul_Reidar_L_snesl_kken.html</guid>
 170                 <pubDate>Wed, 18 Jan 2012 14:30:00 +0100</pubDate>
 171                 <description>&lt;p&gt;I serien med intervjuer av folk i
 172 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-miljøet, har jeg nå
 173 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
 174 men likevel har vært med nesten siden starten av prosjektet.  Jeg
 175 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
 176 mange års erfaring i bruk av Skolelinux.&lt;/p&gt;
 177
 178 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
 179
 180 &lt;p&gt;Jeg driftet tidligere IKT løsningen for skolene i
 181 &lt;a href=&quot;http://www.nord-odal.kommune.no/&quot;&gt;Nord-Odal&lt;/a&gt;.  I dag er jeg
 182 IKT-konsulent for hele kommunen og samarbeider med
 183 &lt;a href=&quot;http://www.hedmarken-ikt.no/&quot;&gt;Hedmark-IKT&lt;/a&gt; for best mulig
 184 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
 185 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
 186 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
 187 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
 188 Nord-Odal. Jeg er fortsatt &quot;IKT-personen&quot; på skolene i kommunen og
 189 følger opp og gjør enkelte mindre endringer der.&lt;/p&gt;
 190
 191 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
 192
 193 &lt;p&gt;Kommunen satset på Skolelinux i 2004.  Jeg var ikke med i
 194 beslutningsprosessen den gang, men ble likevel med fra starten når
 195 dette ble levert.&lt;/p&gt;
 196
 197 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
 198
 199 &lt;p&gt;Fordelene med Skolelinux er rask oppstart, sentral drift av
 200 klientene, klienter som jobber raskt og effektivt, bedre
 201 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
 202 programvare som følger med.  Løsningen med halvtykke klienter gjør at
 203 prosessering skjer lokalt med alltid ferske maskiner.&lt;/p&gt;
 204
 205 &lt;p&gt;Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
 206 utstyr også blir for gammelt selv for Skolelinux.  I forbindelese med
 207 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca 60
 208 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
 209 2004.  Noe var rundt 15 år gammelt, men var fortsatt i bruk. Noen
 210 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
 211 med flash o.l. Det er fullt forståelig.&lt;/p&gt;
 212
 213 &lt;p&gt;Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
 214 legge inn &lt;a href=&quot;http://freemind.sourceforge.net/&quot;&gt;FreeMind&lt;/a&gt;, et
 215 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
 216 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
 217 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
 218 dette programmet allerede lå inne på den nye Skolelinuxløsningen
 219 som nettopp var satt i drift, klart til bruk.&lt;/p&gt;
 220
 221 &lt;p&gt;Vi har de bærbare maskinene på ungdomsskolen i domene med
 222 Skolelinux.  Dette fungerer også meget bra nå. Elevene får opp en
 223 midlertidig windowsprofil når de logger på.  Denne profilen slettes
 224 etter at de logger av, noe som medfører rene profiler hver gang de
 225 starter opp en maskin.  De må lagre i sin Skolelinprofil, noe som
 226 medfører at de får tak i sine filer uavhengig av om de starter en
 227 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
 228 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
 229 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
 230 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
 231 nå.&lt;/p&gt;
 232
 233 &lt;p&gt;Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
 234 og skrivere startes hver natt.  Hyggelig å høre at dette nå skal bli
 235 en standard i Skolelinuxløsningen.  Dette har vært en god hjelp for
 236 oss.&lt;/p&gt;
 237
 238 &lt;p&gt;Elevene er lite opptatt av om de jobber på en Skolelinux eller en
 239 Windowsmaskin bare de har de programmene de trenger og at det virker
 240 når det skal brukes. Vi kjører mest mulig de samme programmene på
 241 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.&lt;/p&gt;
 242
 243 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
 244
 245 &lt;p&gt;Lærere bruker hos oss Windows. Dette fordi de da selv har mer
 246 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
 247 programmer selv når de trenger noe i forhold til kurs o.l de er
 248 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
 249 generelt. Det at de av og til får opp advarsler og lignende gjør også
 250 at de må tenke igjennom og spørre om ting rundt datasikkerhet.&lt;/p&gt;
 251
 252 &lt;p&gt;Det er en del programmer vi bruker som ikke finnes for Linux.  Mest
 253 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
 254 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) .  Dette
 255 finnes gratis for Windows, men er ikke fri programvare.  Vi er opptatt
 256 av at programmer elevene bruker på skolen også kan brukes gratis
 257 hjemme. Det er også en del programmer som brukes til spesielle elever
 258 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
 259 på hvilket OS man bruker.&lt;/p&gt;
 260
 261 &lt;p&gt;For oss er det kombinasjonen mellom Skolelinux og Windows som gir
 262 oss en god og hel løsning. Skolelinux er best der de er gode.&lt;/p&gt;
 263
 264 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
 265
 266 &lt;p&gt;Selv er det LibreOffice jeg bruker til daglig.  Jeg bruker selv en
 267 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
 268 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
 269 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
 270 fungerer på både Linux og Windows og gjerne MAC.&lt;/p&gt;
 271
 272 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
 273 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
 274
 275 &lt;p&gt;Det er viktig at det benyttes programmer som elevene også kan ta i
 276 bruk hjemme.  Det skal da være enkelt, lovlig og gratis for
 277 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles &quot;fri
 278 programvare&quot;.  For skolene tror jeg &quot;gratis&quot; og &quot;funksjonelt&quot; er bedre
 279 begreper enn &quot;fri&quot; i forhold til programmer.  De fleste skiller nok
 280 ikke mellom &quot;fri&quot; og &quot;gratis&quot;. Det er nå svært mange elever som
 281 benytter OpenOffice eller LibreOffice som sin primære kontorpakke
 282 hjemme.&lt;/p&gt;

 290                 <pubDate>Tue, 10 Jan 2012 15:30:00 +0100</pubDate>
 291                 <description>&lt;p&gt;In the Squeeze version of
 292 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; soon
 293 to be released, users of the system will get their default browser
 294 start page set from LDAP, allowing the system administrator to point
 295 all users to the school web page by updating one setting in LDAP.  In
 296 addition to setting the default start page when a machine boots, users
 297 are shown the same page as a welcome page when they log in for the
 298 first time.&lt;/p&gt;
 299
 300 &lt;p&gt;The LDAP object dc=skole,dc=skolelinux,dc=no have an attribute
 301 labeledURI with &quot;http://www/ LDAP for Debian Edu/Skolelinux&quot; as the
 302 default content.  By changing this value to another URL, all users get
 303 to see the page behind this new URL.&lt;/p&gt;
 304
 305 &lt;p&gt;An easy way to update it is by using the ldapvi tool.  It can be
 306 called as &quot;&lt;tt&gt;ldapvi -ZD &#39;(cn=admin)&#39;&lt;/tt&gt;&#39; to update LDAP with the
 307 new setting.&lt;/p&gt;
 308
 309 &lt;p&gt;We have written the code to adjust the default start page and show
 310 the welcome page, and I wonder if there is an easier way to do this
 311 from within Iceweasel instead.&lt;/p&gt;

 320                 <description>&lt;p&gt;I am happy to announce that today we managed to wrap up and publish
 321 the second beta version of
 322 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;.  If
 323 you want to test a LDAP backed Kerberos server with out of the box PXE
 324 configuration for running diskless machines and installing new
 325 machines, check it out.  If you need a software solution for your
 326 school, check it out too.  The full announcement is
 327 &lt;a href=&quot;http://lists.debian.org/debian-edu-announce/2012/01/msg00000.html&quot;&gt;available&lt;/a&gt;

 335                 <guid isPermaLink="true">https://www.hungry.com/~pere/blog/Fixing_an_hanging_debian_installer_for_Debian_Edu.html</guid>
 336                 <pubDate>Tue, 3 Jan 2012 11:25:00 +0100</pubDate>
 337                 <description>&lt;p&gt;During christmas, I have been working getting the next version of
 338 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; ready
 339 for release.  The initial problem I looked at was particularly
 340 interesting.&lt;/p&gt;
 341
 342 &lt;P&gt;The installer would hang at the end when it was doing it
 343 post-installation configuration, and whatevery I did to try to find
 344 the cause and fix it always worked while I tested it, but never when I
 345 integrated it into the installer and ran the installation from
 346 scratch.  I would try to restart processes, close file descriptors,
 347 remove or create files, and the installer would always unblock and
 348 wrap up its tasks.&lt;/p&gt;
 349
 350 &lt;p&gt;Eventually the cause was found.  The kernel was simply running out
 351 of entropy, causing the Kerberos setup to hang waiting for more.
 352 Pressing keys was adding entropy to the kernel, and thus all my tries
 353 to fix the problem worked not because what I was typing to fix it, but
 354 because I was typing.&lt;/P&gt;
 355
 356 &lt;p&gt;The fix I implemented was to add a background process looking at
 357 the level of entropy in the kernel (by checking
 358 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
 359 installer will flush the kernel file buffers and do &#39;find /&#39; to
 360 generate some disk IO.  Disk IO generate entropy in the kernel, and is
 361 one of the few things that can be initated from within the system to
 362 generate entropy.&lt;/p&gt;
 363
 364 &lt;p&gt;The fix is in
 365 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/Documentation/Squeeze/Installation&quot;&gt;beta1
 366 of the Debian Edu/Squeeze&lt;/a&gt; version, and we
 367 &lt;a href=&quot;http://wiki.debian.org/DebianEdu&quot;&gt;welcome more testers and
 368 developers&lt;/a&gt;.  We plan to release beta2 this weekend.&lt;/p&gt;
