<div class="body">
-<p>Just got an email from Tobias Gruetzmacher as a followup on my
-<a href="http://people.skolelinux.org/pere/blog/Broken_umask_handling_with_sshfs.html">previous
-post about sshfs</a>. He reported another problem with sshfs. It
-fail to handle hard links properly. A simple way to spot this is to
-look at the . and .. entries in the directory tree. These should have
-a link count >1, but on sshfs the count is 1. I just tested to see
-what happen when trying to hardlink, and this fail as well:</p>
+<p>The last few days I have spent at work here at the <a
+href="http://www.uio.no/">University of oslo</a> testing if the new
+batch of computers will work with Linux. Every year for the last few
+years the university have organized shared bid of a few thousand
+computers, and this year HP won the bid. Two different desktops and
+five different laptops are on the list this year. We in the UNIX
+group want to know which one of these computers work well with RHEL
+and Ubuntu, the two Linux distributions we currently handle at the
+university.</p>
+
+<p>My test method is simple, and I share it here to get feedback and
+perhaps inspire others to test hardware as well. To test, I PXE
+install the OS version of choice, and log in as my normal user and run
+a few applications and plug in selected pieces of hardware. When
+something fail, I make a note about this in the test matrix and move
+on. If I have some spare time I try to report the bug to the OS
+vendor, but as I only have the machines for a short time, I rarely
+have the time to do this for all the problems I find.</p>
+
+<p>Anyway, to get to the point of this post. Here is the simple tests
+I perform on a new model.</p>
-<pre>
-% ln foo bar
-ln: creating hard link `bar' => `foo': Function not implemented
-%
-</pre>
+<ul>
+
+<li>Is PXE installation working? I'm testing with RHEL6, Ubuntu Lucid
+and Ubuntu Maverik at the moment. If I feel like it, I also test with
+RHEL5 and Debian Edu/Squeeze.</li>
+
+<li>Is X.org working? If the graphical login screen show up after
+installation, X.org is working.</li>
+
+<li>Is hardware accelerated OpenGL working? Running glxgears (in
+package mesa-utils on Ubuntu) and writing down the frames per second
+reported by the program.</li>
+
+<li>Is sound working? With Gnome and KDE, a sound is played when
+logging in, and if I can hear this the test is successful. If there
+are several audio exits on the machine, I try them all and check if
+the Gnome/KDE audio mixer can control where to send the sound. I
+normally test this by playing
+<a href="http://www.nuug.no/aktiviteter/20101012-chef/ ">a HTML5
+video</a> in Firefox/Iceweasel.</li>
+
+<li>Is the USB subsystem working? I test this by plugging in a USB
+memory stick and see if Gnome/KDE notices this.</li>
+
+<li>Is the CD/DVD player working? I test this by inserting any CD/DVD
+I have lying around, and see if Gnome/KDE notices this.</li>
+
+<li>Is any built in camera working? Test using cheese, and see if a
+picture from the v4l device show up.</li>
+
+<li>Is bluetooth working? Use the Gnome/KDE browsing tool to see if
+any bluetooth devices are discovered. In my office, I normally see a
+few.</li>
+
+<li>For laptops, is the SD or Compaq Flash reader working. I have
+memory modules lying around, and stick them in and see if Gnome/KDE
+notice this.</li>
+
+<li>For laptops, is suspecd/hibernate working? I'm testing if the
+special button work, and if the laptop continue to work after
+resume.</li>
+
+<li>For laptops, is the extra buttons working, like audio level,
+adjusting background light, switching on/off external video output,
+switching on/off wifi, bluetooth, etc? The set of buttons differ from
+laptop to laptop, so I just write down which are working and which are
+not.</li>
-<p>I have not yet found time to implement a test for this in my file
-system test code, but believe having working hard links is useful to
-avoid surprised unix programs. Not as useful as working file locking
-and symlinks, which are required to get a working desktop, but useful
-nevertheless. :)</p>
+<li>Some laptops have smart card readers, finger print readers,
+acceleration sensors etc. I rarely test these, as I do not know how
+to quickly test if they are working or not, so I only document their
+existence.</li>
-<p>The latest version of the file system test code is available via
-git from
-<a href="http://github.com/gebi/fs-test">http://github.com/gebi/fs-test</a></p>
+</ul>
+
+<p>By now I suspect you are really curious what the test results are
+for the HP machines I am testing. I'm not done yet, so I will report
+the test results later. For now I can report that HP 8100 Elite work
+fine, and hibernation fail with HP EliteBook 8440p on Ubuntu Lucid,
+and audio fail on RHEL6. Ubuntu Maverik worked with 8440p. As you
+can see, I have most machines left to test. One interesting
+observation is that Ubuntu Lucid has almost twice the framerate than
+RHEL6 with glxgears. No idea why.</p>

<div class="body">
-<p>Jeg skrev for et halvt år siden hvordan
-<a href="http://people.skolelinux.org/pere/blog/Sikkerhet__teater__og_hvordan_gj__re_verden_sikrere.html">samfunnet
-kaster bort ressurser på sikkerhetstiltak som ikke fungerer</a>. Kom
-nettopp over en
-<a href="http://www.askthepilot.com/essays-and-stories/terrorism-tweezers-and-terminal-madness-an-essay-on-security/">historie
-fra en pilot fra USA</a> som kommenterer det samme. Jeg mistenker det
-kun er uvitenhet og autoritetstro som gjør at så få protesterer. Har
-veldig sans for piloten omtalt i <a

-og skulle ønske flere rettet oppmerksomhet mot problemet. Det gir
-ikke meg trygghetsfølelse på flyplassene når jeg ser at
-flyplassadministrasjonen kaster bort folk, penger og tid på tull i
-stedet for ting som bidrar til reell økning av sikkerheten. Det
-forteller meg jo at vurderingsevnen til de som burde bidra til økt
-sikkerhet er svært sviktende, noe som ikke taler godt for de andre
-tiltakene.</p>
-
-<p>Mon tro hva som skjer hvis det fantes en enkel brosjyre å skrive ut
-fra Internet som forklarte hva som er galt med sikkerhetsopplegget på
-flyplassene, og folk skrev ut og la en bunke på flyplassene når de
-passerte. Kanskje det ville fått flere til å få øynene opp for
-problemet.</p>
-
-<p>Personlig synes jeg flyopplevelsen er blitt så avskyelig at jeg
-forsøker å klare meg med tog, bil og båt for å slippe ubehaget. Det
-er dog noe vanskelig i det langstrakte Norge og for å kunne besøke de
-delene av verden jeg ønsker å nå. Mistenker at flere har det slik, og
-at dette går ut over inntjeningen til flyselskapene. Det er antagelig
-en god ting sett fra et miljøperspektiv, men det er en annen sak.</p>
+<p>As I continue to explore
+<a href="http://www.bitcoin.org/">BitCoin</a>, I've starting to wonder
+what properties the system have, and how it will be affected by laws
+and regulations here in Norway. Here are some random notes.</p>
+
+<p>One interesting thing to note is that since the transactions are
+verified using a peer to peer network, all details about a transaction
+is known to everyone. This means that if a BitCoin address has been
+published like I did with mine in my initial post about BitCoin, it is
+possible for everyone to see how many BitCoins have been transfered to
+that address. There is even a web service to look at the details for
+all transactions. There I can see that my address
+<a href="http://blockexplorer.com/address/15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a>
+have received 16.06 Bitcoin, the
+<a href="http://blockexplorer.com/address/1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3">1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3</a>
+address of Simon Phipps have received 181.97 BitCoin and the address
+<a href="http://blockexplorer.com/address/1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt">1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt</A>
+of EFF have received 2447.38 BitCoins so far. Thank you to each and
+every one of you that donated bitcoins to support my activity. The
+fact that anyone can see how much money was transfered to a given
+address make it more obvious why the BitCoin community recommend to
+generate and hand out a new address for each transaction. I'm told
+there is no way to track which addresses belong to a given person or
+organisation without the person or organisation revealing it
+themselves, as Simon, EFF and I have done.</p>
+
+<p>In Norway, and in most other countries, there are laws and
+regulations limiting how much money one can transfer across the border
+without declaring it. There are money laundering, tax and accounting
+laws and regulations I would expect to apply to the use of BitCoin.
+If the Skolelinux foundation
+(<a href="http://linuxiskolen.no/slxdebianlabs/donations.html">SLX
+Debian Labs</a>) were to accept donations in BitCoin in addition to
+normal bank transfers like EFF is doing, how should this be accounted?
+Given that it is impossible to know if money can across the border or
+not, should everything or nothing be declared? What exchange rate
+should be used when calculating taxes? Would receivers have to pay
+income tax if the foundation were to pay Skolelinux contributors in
+BitCoin? I have no idea, but it would be interesting to know.</p>
+
+<p>For a currency to be useful and successful, it must be trusted and
+accepted by a lot of users. It must be possible to get easy access to
+the currency (as a wage or using currency exchanges), and it must be
+easy to spend it. At the moment BitCoin seem fairly easy to get
+access to, but there are very few places to spend it. I am not really
+a regular user of any of the vendor types currently accepting BitCoin,
+so I wonder when my kind of shop would start accepting BitCoins. I
+would like to buy electronics, travels and subway tickets, not herbs
+and books. :) The currency is young, and this will improve over time
+if it become popular, but I suspect regular banks will start to lobby
+to get BitCoin declared illegal if it become popular. I'm sure they
+will claim it is helping fund terrorism and money laundering (which
+probably would be true, as is any currency in existence), but I
+believe the problems should be solved elsewhere and not by blaming
+currencies.</p>
+
+<p>The process of creating new BitCoins is called mining, and it is
+CPU intensive process that depend on a bit of luck as well (as one is
+competing against all the other miners currently spending CPU cycles
+to see which one get the next lump of cash). The "winner" get 50
+BitCoin when this happen. Yesterday I came across the obvious way to
+join forces to increase ones changes of getting at least some coins,
+by coordinating the work on mining BitCoins across several machines
+and people, and sharing the result if one is lucky and get the 50
+BitCoins. Check out
+<a href="http://www.bluishcoder.co.nz/bitcoin-pool/">BitCoin Pool</a>
+if this sounds interesting. I have not had time to try to set up a
+machine to participate there yet, but have seen that running on ones
+own for a few days have not yield any BitCoins througth mining
+yet.</p>
+
+<p>Update 2010-12-15: Found an <a
+href="http://inertia.posterous.com/reply-to-the-underground-economist-why-bitcoi">interesting
+criticism</a> of bitcoin. Not quite sure how valid it is, but thought
+it was interesting to read. The arguments presented seem to be
+equally valid for gold, which was used as a currency for many years.</p>

-<p>Denne høsten skal endelig alle Osloskolene få mulighet til å bruke
-<a href="http://www.skolelinux.org/">Skolelinux</a>. Ny IT-løsning
-har vært rullet ut i noen måneder nå, og så vidt jeg fikk vite før
-sommeren skulle alle skoler ha nytt opplegg på plass før oppstart nå i
-høst. På alle skolene skal en kunne velge ved installasjon om en skal
-ha Windows eller Skolelinux på maskinene, og en kan i tillegg
-PXE-boote maskinene over nett som tynne klienter eller diskløse
-arbeidsstasjoner. Jeg er spent på hvor mange skoler som velger å ta i
-bruk Skolelinux, og gleder meg til å se hvordan dette utvikler seg.
-Løsningen leveres av
-<a href="http://www.logica.no/">Logica</a> med
-<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a> som
-underleverandør, og jeg har vært involvert i utviklingen av løsningen
-via Skolelinux Drift AS siden prosjektet starter. Jeg synes det er
-fantastisk at Skolelinux er kommet så langt siden vi startet i 2001 at
-alle elevene i Osloskolene nå skal få mulighet til å bruke
-løsningen. Jeg håper de vil sette pris på alle de
-<a href="http://www.skolelinux.no/linux-signpost/">fantastiske
-brukerprogrammene</a> som er tilgjengelig i Skolelinux.</p>
+<p>Via <a href="http://webmink.com/2010/12/10/links-for-2010-12-10/">en
+blogpost fra Simon Phipps i går</a>, fant jeg en referanse til
+<a href="http://www.washingtontimes.com/news/2010/dec/9/exposed-tsas-x-rated-scanner-fraud/">en
+artikkel i Washington Times</a> som igjen refererer til en artikkel i

+med tittelen
+"<a href="http://springerlink.com/content/g6620thk08679160/fulltext.html">An

+<a href="http://www.dailysquib.co.uk/?a=2389&c=124">pornoscannerne</a>
+som kler av reisende på flyplasser ikke er i stand til å avsløre det
+produsenten og amerikanske myndigheter sier de skal avsløre. Kort
+sagt, de bedrer ikke sikkerheten. Reisende må altså la ansatte på
+flyplasser <a href="http://www.thousandsstandingaround.org/">se dem
+nakne eller la seg beføle i skrittet</a> uten grunn. Jeg vil
+fortsette å nekte å bruke disse pornoskannerne, unngå flyplasser der
+de er tatt i bruk, og reise med andre transportmidler enn fly hvis jeg
+kan.</p>

- mode_t retval = 0;
- int fd = open(name, O_RDWR|O_CREAT|O_LARGEFILE, mode);

+hvordan data skal lagres er fortsatt uavklart.</p>

-<p>I Norge pågår en prosess for å
-<a href="http://www.e-valg.dep.no/">innføre elektronisk
-stemmegiving</a> ved kommune- og stortingsvalg. Dette skal
-introduseres i 2011. Det er all grunn til å tro at valg i Norge ikke
-vil være til å stole på hvis dette blir gjennomført. Da det hele var
-oppe til høring i 2006 forfattet jeg
-<a href="http://www.nuug.no/dokumenter/valg-horing-2006-09.pdf">en
-høringsuttalelse fra NUUG</a> (og EFN som hengte seg på) som skisserte
-hvilke punkter som må oppfylles for at en skal kunne stole på et valg,
-og elektronisk stemmegiving mangler flere av disse. Elektronisk
-stemmegiving er for alle praktiske formål å putte ens stemme i en sort
-boks under andres kontroll, og satse på at de som har kontroll med
-boksen er til å stole på - uten at en har mulighet til å verifisere
-dette selv. Det er ikke slik en gjennomfører demokratiske valg.</p>
-
-<p>Da problemet er fundamentalt med hvordan elektronisk stemmegiving
-må fungere for at også ikke-krypografer skal kunne delta, har det vært
-mange rapporter om hvordan elektronisk stemmegiving har sviktet i land
-etter land. En
-<a href="http://wiki.nuug.no/uttalelser/2006-elektronisk-stemmegiving">liten
-samling referanser</a> finnes på NUUGs wiki. Den siste er fra India,
-der valgkomisjonen har valgt
-<a href="http://www.freedom-to-tinker.com/blog/jhalderm/electronic-voting-researcher-arrested-over-anonymous-source">å
-pusse politiet på en forsker</a> som har dokumentert svakheter i
-valgsystemet.</p>
-
-<p>Her i Norge har en valgt en annen tilnærming, der en forsøker seg
-med teknobabbel for å få befolkningen til å tro at dette skal bli
-sikkert. Husk, elektronisk stemmegiving underminerer de demokratiske
-valgene i Norge, og bør ikke innføres.</p>
-
-<p>Den offentlige diskusjonen blir litt vanskelig av at media har
-valgt å kalle dette "evalg", som kan sies å både gjelde elektronisk
-opptelling av valget som Norge har gjort siden 60-tallet og som er en
-svært god ide, og elektronisk opptelling som er en svært dårlig ide.
-Diskusjonen gir ikke mening hvis en skal diskutere om en er for eller
-mot "evalg", og jeg forsøker derfor å være klar på at jeg snakker om
-elektronisk stemmegiving og unngå begrepet "evalg".</p>
+<p>A few days ago, I was introduces to some students in the robot
+student assosiation <a href="http://www.robotica.no/">Robotica
+Osloensis</a> at the University of Oslo where I work, who planned to
+get their own 3D printer. They wanted to learn from me based on my

+offered them to borrow my reprap kit, as I never had time to complete
+the build and this seem unlike to change any time soon. I look
+forward to see how this goes. This monday their volunteer driver

+last exam is over so they can start work on getting the 3D printer
+operational.</p>
+
+<p>The robotic group have already build several robots on their own,
+and seem capable of getting the reprap operational. I really look
+forward to being able to print all the cool 3D designs published on
+<a href="http://www.thingiverse.com/">Thingiverse</a>. I even got
+some 3D scans I got made during Dagen@IFI when one of the groups at

-<p>I dag fikk jeg endelig tittet litt på mine nyinnkjøpte roboter, og
-har brukt noen timer til å google etter interessante referanser og
-aktuell kildekode for bruk på Linux. Det mest lovende så langt er
-<a href="http://ispykee.toyz.org/">ispykee</a>, som har en
-BSD-lisensiert linux-daemon som står som mellomledd mellom roboter på
-lokalnettet og en sentral tjeneste der en iPhone kan koble seg opp for
-å fjernstyre roboten. Linux-daemonen implementerer deler av
-protokollen som roboten forstår. Etter å ha knotet litt med å oppnå
-kontakt med roboten (den oppretter et eget ad-hoc wifi-nett, så jeg
-måtte gå av mitt vanlige nett for å få kontakt), og kommet frem til at
-den lytter på IP-port 9000 og 9001, gikk jeg i gang med å finne ut
-hvordan jeg kunne snakke med roboten vha. disse portene. Robotbiten
-av protokollen er publisert av produsenten med GPL-lisens, slik at det
-er mulig å se hvordan protokollen fungerer. Det finnes en java-klient
-for Android som så ganske snasen ut, men fant ingen kildekode for
-denne. Derimot hadde iphone-løsningen kildekode, så jeg tok
-utgangspunkt i den.</p>
-
-<p>Daemonen ville i utgangspunktet forsøke å kontakte den sentrale
-tjenesten som iphone-programmet kobler seg til. Jeg skrev dette om
-til i stedet å sette opp en nettverkstjeneste på min lokale maskin,
-som jeg kan koble meg opp til med telnet og gi kommandoer til roboten
-(act, forward, right, left, etc). Det involverte i praksis å bytte ut
-socket()/connect() med socket()/bind()/listen()/accept() for å gjøre
-klienten om til en tjener.</p>
-
-<p>Mens jeg har forsøkt å få roboten til å bevege seg har min samboer
-skrudd sammen resten av roboten for å få montert kamera og plastpynten
-(armer, plastfiber for lys). Nå er det hele montert, og roboten er
-klar til bruk. Må få flyttet den over til mitt vanlige trådløsnett
-før det blir praktisk, men de bitene av protokollen er ikke
-implementert i ispykee-daemonen, så der må jeg enten få tak i en mac
-eller en windows-maskin, eller implementere det selv.</p>
-
-<p>Vi var tre som kjøpte slike roboter, og vi har blitt enige om å
-samle notater og referanser på <a

+<p>In the latest issue of Linux Journal, the readers choices were
+presented, and the winner among the multimedia player were VLC.
+Personally, I like VLC, and it is my player of choice when I first try
+to play a video file or stream. Only if VLC fail will I drag out
+gmplayer to see if it can do better. The reason is mostly the failure
+model and trust. When VLC fail, it normally pop up a error message
+reporting the problem. When mplayer fail, it normally segfault or
+just hangs. The latter failure mode drain my trust in the program.<p>
+
+<p>But even if VLC is my player of choice, we have choosen to use
+mplayer in <a href="http://www.skolelinux.org/">Debian
+Edu/Skolelinux</a>. The reason is simple. We need a good browser
+plugin to play web videos seamlessly, and the VLC browser plugin is
+not very good. For example, it lack in-line control buttons, so there
+is no way for the user to pause the video. Also, when I
+<a href="http://wiki.debian.org/DebianEdu/BrowserMultimedia">last
+tested the browser plugins</a> available in Debian, the VLC plugin
+failed on several video pages where mplayer based plugins worked. If
+the browser plugin for VLC was as good as the gecko-mediaplayer
+package (which uses mplayer), we would switch.</P>
+
+<p>While VLC is a good player, its user interface is slightly
+annoying. The most annoying feature is its inconsistent use of
+keyboard shortcuts. When the player is in full screen mode, its
+shortcuts are different from when it is playing the video in a window.
+For example, space only work as pause when in full screen mode. I
+wish it had consisten shortcuts and that space also would work when in
+window mode. Another nice shortcut in gmplayer is [enter] to restart
+the current video. It is very nice when playing short videos from the
+web and want to restart it when new people arrive to have a look at
+what is going on.</p>

+
+<p>Å elektronisk overvåke sine barn er ikke å gjøre dem en tjeneste,
+men et overgrep mot individer i utvikling som bør læres opp til å ta
+egne valg.</p>
+
+<p>For å sitere Datatilsynets nye leder, Bjørn Erik Thon, i
+<a href="http://www.idg.no/computerworld/article174262.ece">et intervju
+med Computerworld Norge</A>:</p>
+
+<p><blockquote>
+- For alle som har barn, meg selv inkludert, er førstetanken at det
+hadde vært fint å vite hvor barnet sitt er til enhver tid. Men ungene
+har ikke godt av det. De er små individer som skal søke rundt og finne
+sine små gjemmesteder og utvide horisonten, uten at foreldrene ser dem
+i kortene. Det kan være fristende, men jeg ville ikke gått inn i
+dette.
+</blockquote></p>
+
+<p>Det er skremmende å se at DND mener en tjeneste som legger opp til
+slike overgrep bør hedres. Å flytte oppveksten for barn inn i en
+virtuell
+<a href="http://en.wikipedia.org/wiki/Panopticon">Panopticon</a> er et
+grovt overgrep og vil gjøre skade på barnenes utvikling, og foreldre

+
+<p>Blipper-tjenesten får meg til å tenke på bøkene til
+<a href="http://en.wikipedia.org/wiki/John_Twelve_Hawks">John Twelve
+Hawks</a>, som forbilledlig beskriver hvordan et totalitært
+overvåkningssamfunn bygges sakte men sikkert rundt oss, satt sammen av
+gode intensjoner og manglende bevissthet om hvilke prinsipper et
+liberalt demokrati er fundamentert på. Jeg har hatt stor glede av å
+lese alle de tre bøkene.</p>

+ <div class="date">2010-11-22 14:15</div>
<div class="body">
-<p>As reported earlier, the last few days I have looked at how Debian
-Edu clients are configured, and tried to get rid of all hardcoded
-configuration settings on the clients. I believe the work to be
-mostly done, and the clients seem to work just fine with dynamically
-generated configuration.</p>
-
-<p>What is the point, you might ask? The point is to allow a Debian
-Edu desktop to integrate into an existing network infrastructure
-without any manual configuration.</p>
-
-<p>This is what happens when installing a Debian Edu client here at
-the University of Oslo using PXE. With the PXE installation, I am
-asked for language (Norwegian Bokmål), locality (Norway) and keyboard
-layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
-accept to reformat the hard drive (yes), if I want to submit info to
-popcon.debian.org (no) and root password (secret). After answering
-these questions, the installer goes ahead and does its thing, and
-after around 50 minutes it is done. I press enter to finish the
-installation, and the machine reboots into KDE. When the machine is
-ready and kdm asks for login information, I enter my university
-username and password, am told by kdm that a local home directory has
-been created and that I must log in again, and finally log in with the
-same username and password to the KDE 4.4 desktop. At no point during
-this process did it ask for university specific settings, and all the
-required configuration was dynamically detected using information
-fetched via DHCP and DNS. The roaming workstation is now ready for
-use.</p>
-
-<p>How was this done, you might wonder? First of all, here is the
-list of things that need to be configured on the client to get it
-working properly out of the box:</p>
-
-<ul>
-<li>IP address/netmask and DNS server.</li>
-<li>Web proxy URL.</li>
-<li>LDAP server for NSS directory information (user, group, etc).</li>
-<li>Kerberos server for PAM password checking.</li>
-<li>SMB mount point to access the network home directory. (*)</li>
-<li>Central syslog server to send syslog messages to. (*)</li>
-<li>Sitesummary collector URL to submit info to central server. (*)</li>
-</ul>
-
-<p>(Hm, did I forget anything? Let me knew if I did.)</p>
-
-<p>The points marked (*) are not required to be able to use the
-machine, but needed to provide central storage and allowing system
-administrators to track their machines. Since yesterday, everything
-but the sitesummary collector URL is dynamically discovered at boot
-and installation time in the svn version of Debian Edu.</p>
-
-<p>The IP and DNS setup is fetched during boot using DHCP as usual.
-When a DHCP update arrives, the proxy setup is updated by looking for
-http://wpat/wpad.dat and using the content of this WPAD file to
-configure the http and ftp proxy in /etc/environment and
-/etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
-hook to ensure that the client stops using the Debian Edu proxy when
-it is moved outside the Debian Edu network, and instead uses any local
-proxy present on the new network when it moves around.</p>
-
-<p>The DNS names of the LDAP, Kerberos and syslog server and related
-configuration are generated using DNS information at boot. First the
-installer looks for a host named ldap in the current DNS domain. If
-not found, it looks for _ldap._tcp SRV records in DNS instead. If an
-LDAP server is found, its root DSE entry is requested and the
-attributes namingContexts and defaultNamingContext are used to
-determine which LDAP base to use for NSS. If there are several
-namingContexts attibutes and the defaultNamingContext is present, that
-LDAP subtree is used as the base. If defaultNamingContext is missing,
-the subtrees listed as namingContexts are searched in sequence for any
-object with class posixAccount or posixGroup, and the first one with
-such an object is used as the LDAP base. For Kerberos, a similar
-search is done by first looking for a host named kerberos, and then
-for the _kerberos._tcp SRV record. I've been unable to find a way to
-look up the Kerberos realm, so for this the upper case string of the
-current DNS domain is used.</p>
-
-<p>For the syslog server, the hosts syslog and loghost are searched
-for, and the _syslog._udp SRV record is consulted if no such host is
-found. This algorithm works for both Debian Edu and the University of
-Oslo. A similar strategy would work for locating the sitesummary
-server, but have not been implemented yet. I decided to fetch and
-save these settings during installation, to make sure moving to a
-different network does not change the set of users being allowed to
-log in nor the passwords required to log in. Usernames and passwords
-will be cached by sssd when the user logs in on the Debian Edu
-network, and will not change as the laptop move around. For a
-non-roaming machine, there is no caching, but given that it is
-supposed to stay in place it should not matter much. Perhaps we
-should switch those to use sssd too?</p>
-
-<p>The user's SMB mount point for the network home directory is
-located when the user logs in for the first time. The LDAP server is
-consulted to look for the user's LDAP object and the sambaHomePath
-attribute is used if found. If it isn't found, the home directory
-path fetched from NSS is used instead. Assuming the path is of the
-form /site/server/directory/username, the second part is looked up in
-DNS and used to generate a SMB URL of the form
-smb://server.domain/username. This algorithm works for both Debian
-edu and the University of Oslo. Perhaps there are better attributes
-to use or a better algorithm that works for more sites, but this will
-do for now. :)</p>
-
-<p>This work should make it easier to integrate the Debian Edu clients
-into any LDAP/Kerberos infrastructure, and make the current setup even
-more flexible than before. I suspect it will also work for thin
-client servers, allowing one to easily set up LTSP and hook it into a
-existing network infrastructure, but I have not had time to test this
-yet.</p>
-
-<p>If you want to help out with implementing these things for Debian
-Edu, please contact us on debian-edu@lists.debian.org.</p>
-
-<p>Update 2010-08-09: Simon Farnsworth gave me a heads-up on how to
-detect Kerberos realm from DNS, by looking for _kerberos TXT entries
-before falling back to the upper case DNS domain name. Will have to
-implement it for Debian Edu. :)</p>
+<p>Michael Biebl suggested to me on IRC, that I changed my automated
+upgrade testing of the
+<a href="http://people.skolelinux.org/~pere/debian-upgrade-testing/">Lenny
+Gnome and KDE Desktop</a> to do <tt>apt-get autoremove</tt> when using apt-get.
+This seem like a very good idea, so I adjusted by test scripts and

<div class="body">
-<p>A few years ago, I was involved in a project planning to use
-Windows file servers as home directory servers for Debian
-Edu/Skolelinux machines. This was thought to be no problem, as the
-access would be through the SMB network file system protocol, and we
-knew other sites used SMB with unix and samba as the file server to
-mount home directories without any problems. But, after months of
-struggling, we had to conclude that our goal was impossible.</p>
-
-<p>The reason is simply that while SMB can be used for home
-directories when the file server is Samba running on Unix, this only
-work because of Samba have some extensions and the fact that the
-underlying file system is a unix file system. When using a Windows
-file server, the underlying file system do not have POSIX semantics,
-and several programs will fail if the users home directory where they
-want to store their configuration lack POSIX semantics.</p>
-
-<p>As part of this work, I wrote a small C program I want to share
-with you all, to replicate a few of the problematic applications (like
-OpenOffice.org and GCompris) and see if the file system was working as
-it should. If you find yourself in spooky file system land, it might
-help you find your way out again. This is the fs-test.c source:</p>
+<p>Most of the computers in use by the
+<a href="http://www.skolelinux.org/">Debian Edu/Skolelinux project</a>
+are virtual machines. And they have been Xen machines running on a
+fairly old IBM eserver xseries 345 machine, and we wanted to migrate
+them to KVM on a newer Dell PowerEdge 2950 host machine. This was a
+bit harder that it could have been, because we set up the Xen virtual
+machines to get the virtual partitions from LVM, which as far as I
+know is not supported by KVM. So to migrate, we had to convert
+several LVM logical volumes to partitions on a virtual disk file.</p>
+
+<p>I found
+<a href="http://searchnetworking.techtarget.com.au/articles/35011-Six-steps-for-migrating-Xen-virtual-machines-to-KVM">a
+nice recipe</a> to do this, and wrote the following script to do the
+migration. It uses qemu-img from the qemu package to make the disk
+image, parted to partition it, losetup and kpartx to present the disk
+image partions as devices, and dd to copy the data. I NFS mounted the
+new servers storage area on the old server to do the migration.</p>

-<p>I do not remember the exact details of the problems we saw, but one
-of them was with locking, where if I remember correctly, POSIX allow a
-read-only lock to be upgraded to a read-write lock without unlocking
-the read-only lock (while Windows do not). Another was a bug in the
-CIFS/SMB client implementation in the Linux kernel where directory
-meta information would be wrong for a fraction of a second, making
-OpenOffice.org fail to create its deep directory tree because it was
-not allowed to create files in its freshly created directory.</p>
-
-<p>Anyway, here is a nice tool for your tool box, might you never need
-it. :)</p>
-
-<p>Update 2010-08-27: Michael Gebetsroither report that he found the
-script so useful that he created a GIT repository and stored it in
-<a href="http://github.com/gebi/fs-test">http://github.com/gebi/fs-test</a>.</p>
+<p>After doing this, I booted a Debian CD in rescue mode in KVM with
+the new disk image attached, installed grub-pc and linux-image-686 and
+set up grub to boot from the disk image. After this, the KVM machines
+seem to work just fine.</p>
