Immediatly after installation a school -server running all services needed for a school network is set up just -waiting for users and machines being added via GOsa², a comfortable -Web-UI. A netbooting environment is prepared using PXE, so after -initial installation of the main server from CD, DVD or USB stick all -other machines can be installed via the network.</p> + Testing sysvinit from experimental in Debian Hurd + http://people.skolelinux.org/pere/blog/Testing_sysvinit_from_experimental_in_Debian_Hurd.html + http://people.skolelinux.org/pere/blog/Testing_sysvinit_from_experimental_in_Debian_Hurd.html + Mon, 3 Feb 2014 13:40:00 +0100 + <p>A few days ago I decided to try to help the Hurd people to get +their changes into sysvinit, to allow them to use the normal sysvinit +boot system instead of their old one. This follow up on the +<a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great +Google Summer of Code work</a> done last summer by Justus Winter to +get Debian on Hurd working more like Debian on Linux. To get started, +I downloaded a prebuilt hard disk image from +<a href="http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz">http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz</a>, +and started it using virt-manager.</p> + +<p>The first think I had to do after logging in (root without any +password) was to get the network operational. I followed +<a href="https://www.debian.org/ports/hurd/hurd-install">the +instructions on the Debian GNU/Hurd ports page</a> and ran these +commands as root to get the machine to accept a IP address from the +kvm internal DHCP server:</p> + +<p><blockquote><pre> +settrans -fgap /dev/netdde /hurd/netdde +pkill pfinet +pkill devnode +dhclient -v /dev/eth0 +</pre></blockquote></p> + +<p>After this, the machine had internet connectivity, and I could +upgrade it and install the sysvinit packages from experimental and +enable it as the default boot system in Hurd.</p> + +<p>But before I did that, I set a password on the root user, as ssh is +running on the machine it for ssh login to work a password need to be +set. Also, note that a bug somewhere in openssh on Hurd block +compression from working. Remember to turn that off on the client +side.</p> + +<p>Run these commands as root to upgrade and test the new sysvinit +stuff:</p> + +<p><blockquote><pre> +cat > /etc/apt/sources.list.d/experimental.list &lt;&lt;EOF +deb http://http.debian.net/debian/ experimental main +EOF +apt-get update +apt-get dist-upgrade +apt-get install -t experimental initscripts sysv-rc sysvinit \ + sysvinit-core sysvinit-utils +update-alternatives --config runsystem +</pre></blockquote></p> + +<p>To reboot after switching boot system, you have to use +<tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not +yet a sysvinit process able to receive the signals from the normal +'reboot' command. After switching to sysvinit as the boot system, +upgrading every package and rebooting, the network come up with DHCP +after boot as it should, and the settrans/pkill hack mentioned at the +start is no longer needed. But for some strange reason, there are no +longer any login prompt in the virtual console, so I logged in using +ssh instead. + +<p>Note that there are some race conditions in Hurd making the boot +fail some times. No idea what the cause is, but hope the Hurd porters +figure it out. At least Justus said on IRC (#debian-hurd on +irc.debian.org) that they are aware of the problem. A way to reduce +the impact is to upgrade to the Hurd packages built by Justus by +adding this repository to the machine:</p> + +<p><blockquote><pre> +cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF +deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main +EOF +</pre></blockquote></p> + +<p>At the moment the prebuilt virtual machine get some packages from +http://ftp.debian-ports.org/debian, because some of the packages in +unstable do not yet include the required patches that are lingering in +BTS. This is the completely list of "unofficial" packages installed:</p> + +<p><blockquote><pre> +# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))' +i emacs - GNU Emacs editor (metapackage) +i gdb - GNU Debugger +i hurd-recommended - Miscellaneous translators +i isc-dhcp-client - ISC DHCP client +i isc-dhcp-common - common files used by all the isc-dhcp* packages +i libc-bin - Embedded GNU C Library: Binaries +i libc-dev-bin - Embedded GNU C Library: Development binaries +i libc0.3 - Embedded GNU C Library: Shared libraries +i A libc0.3-dbg - Embedded GNU C Library: detached debugging symbols +i libc0.3-dev - Embedded GNU C Library: Development Libraries and Hea +i multiarch-support - Transitional package to ensure multiarch compatibilit +i A x11-common - X Window System (X.Org) infrastructure +i xorg - X.Org X Window System +i A xserver-xorg - X.Org X server +i A xserver-xorg-input-all - X.Org X server -- input driver metapackage +# +</pre></blockquote></p> + +<p>All in all, testing hurd has been an interesting experience. :) +X.org did not work out of the box and I never took the time to follow +the porters instructions to fix it.

It is sometimes claimed to be ideal for illegal +activity, which I believe is quite a long way from the truth. At least +I would not conduct illegal money transfers using a system where the +details of every transaction are kept forever. This point is +investigated in +<a href="https://www.usenix.org/publications/login">USENIX ;login:</a> +from December 2013, in the article +"<a href="https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf">A +Fistful of Bitcoins - Characterizing Payments Among Men with No +Names</a>" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill +Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage. They +analyse the transaction log in the Bitcoin system, using it to find +addresses belong to individuals and organisations and follow the flow +of money from both Bitcoin theft and trades on Silk Road to where the +money end up. This is how they wrap up their article:</p> -<p>This is the first test release based on Wheezy (which currently is -not released yet). Basically this is an updated and slightly improved -version compared to the Squeeze release.</p> +<p><blockquote> +<p>"To demonstrate the usefulness of this type of analysis, we turned +our attention to criminal activity. In the Bitcoin economy, criminal +activity can appear in a number of forms, such as dealing drugs on +Silk Road or simply stealing someone else’s bitcoins. We followed the +flow of bitcoins out of Silk Road (in particular, from one notorious +address) and from a number of highly publicized thefts to see whether +we could track the bitcoins to known services. Although some of the +thieves attempted to use sophisticated mixing techniques (or possibly +mix services) to obscure the flow of bitcoins, for the most part +tracking the bitcoins was quite straightforward, and we ultimately saw +large quantities of bitcoins flow to a variety of exchanges directly +from the point of theft (or the withdrawal from Silk Road).</p> + +<p>As acknowledged above, following stolen bitcoins to the point at +which they are deposited into an exchange does not in itself identify +the thief; however, it does enable further de-anonymization in the +case in which certain agencies can determine (through, for example, +subpoena power) the real-world owner of the account into which the +stolen bitcoins were deposited. Because such exchanges seem to serve +as chokepoints into and out of the Bitcoin economy (i.e., there are +few alternative ways to cash out), we conclude that using Bitcoin for +money laundering or other illicit purposes does not (at least at +present) seem to be particularly attractive."</p> +</blockquote><p> + +<p>These researches are not the first to analyse the Bitcoin +transaction log. The 2011 paper +"<a href="http://arxiv.org/abs/1107.4524">An Analysis of Anonymity in +the Bitcoin System</A>" by Fergal Reid and Martin Harrigan is +summarized like this:</p> -<p><strong>Software updates</strong></p> -<ul> - <li>Install freemind (0.9.0) by default, and stop installing vym by - default.</li> - <li>Install chromium (26.0.1410.43) by default.</li> - <li>Install goplay (0.5-1.1) to make golearn available by default.</li> - <li>Updated support for Japanese input methods, now based on - ibus-anthy.</li> -</ul> +<p><blockquote> +"Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a +complicated issue. Within the system, users are identified by +public-keys only. An attacker wishing to de-anonymize its users will +attempt to construct the one-to-many mapping between users and +public-keys and associate information external to the system with the +users. Bitcoin tries to prevent this attack by storing the mapping of +a user to his or her public-keys on that user's node only and by +allowing each user to generate as many public-keys as required. In +this chapter we consider the topological structure of two networks +derived from Bitcoin's public transaction history. We show that the +two networks have a non-trivial topological structure, provide +complementary views of the Bitcoin system and have implications for +anonymity. We combine these structures with external information and +techniques such as context discovery and flow analysis to investigate +an alleged theft of Bitcoins, which, at the time of the theft, had a +market value of approximately half a million U.S. dollars." +</blockquote></p> -<p><strong>Other changes</strong></p> -<ul> +<p>I hope these references can help kill the urban myth that Bitcoin +is anonymous. It isn't really a good fit for illegal activites.

The company behind it provide +<a href="https://scan.coverity.com/">check of free software projects as +a community service</a>, and many hundred free software projects are +already checked. A few days ago I decided to have a closer look at +the Coverity system, and discovered that the +<a href="http://www.gnu.org/software/gnash/">gnash</a> and +<a href="http://sourceforge.net/projects/ipmitool/">ipmitool</a> +projects I am involved with was already registered. But these are +fairly big, and I would also like to have a small and easy project to +check, and decided to <a href="http://scan.coverity.com/projects/1179">request +checking of the chrpath project</a>. It was +added to the checker and discovered seven potential defects. Six of +these were real, mostly resource "leak" when the program detected an +error. Nothing serious, as the resources would be released a fraction +of a second later when the program exited because of the error, but it +is nice to do it right in case the source of the program some time in +the future end up in a library. Having fixed all defects and added +<a href="https://lists.alioth.debian.org/mailman/listinfo/chrpath-devel">a +mailing list for the chrpath developers</a>, I decided it was time to +publish a new release.

Say hello +to <a href="https://www.ohloh.net/accounts/Natureshadow">Dominik +George</a>.</p> + +<!-- http://www.dominik-george.de/images/foto.jpg --> + +<p><strong>Who are you, and how do you spend your days?</strong></p> + +<p>I am a 23 year-old student from Germany who has spent half of his +life with open source. In "real life", I am, as already mentioned, a +student in the fields of Computer Science, Electrical Engineering, +Information Technologies and Anglistics. Due to my (only partially +voluntary) huge engagement in the open source world, these things are +a bit vacant right now however.</p> + +<p>I also have been working as a project teacher at a Gymasnium +(public school) for various years now. I took up that work some time +around 2005 when still attending that school myself and have continued +it until today. I also had been running the (kind of very advanced) +network of that school together with a team of very interested and +talented students in the age of 11 to 15 years, who took the chance to +learn a lot about open source and networking before I left the school +to help building another school's informational education concept from +scratch.</p> + +<p>That said, one might see me as a kind of "glue" between school kids +and the elderly of teachers as well as between the open source +ecosystem and the (even more complex) educational ecosystem.</p> + +<p>When I am not busy with open source or education, I like Geocaching +and cycling.</p> + +<p><strong>How did you get in contact with the Skolelinux / Debian Edu +project?</strong></p> + +<p>I think that happened some time around 2009 when I first attended +<a href="http://www.froscon.org">FrOSCon</a> and visited the project +booth. I think I wasn't too interested back then because I used to +have an attitude of disliking software that does too much stuff on its +own. Maybe I was too inexperienced to realise the upsides of an +"out-of-the-box" solution ;).</p> + +<p>The first time I actively talked to Skolelinux people was at +<a href="http://www.openrheinruhr.de">OpenRheinRuhr</a> 2011 when the +BiscuIT project, a home-grewn software used by my school for various +really cool things from timetables and class contact lists to lunch +ordering, student ID card printing and project elections first got to +a stage where it could have been published. I asked the Skolelinux +guys running the booth if the project were interested in it and gave a +small demonstration, but there wasn't any real feedback and the guys +seemed rather uninterested.</p> + +<p>After I left the school where I developed the software, it got +mostly lost, but I am now reimplementing it for my new school. I have +reusability and compatibility in mind, and I hop there will be a new +basis for contributing it to the Skolelinux project ;)!</p> + +<p><strong>What do you see as the advantages of Skolelinux / Debian +Edu?</strong></p> + +<p>The most important advantage seems to be that it "just +works". After overcoming some minor (but still very annoying) glitches +in the installer, I got a fully functional, working school network, +without the month-long hassle I experienced when setting all that up +from scratch in earlier years. And above that, it rocked - I didn't +have any real hardware at hand, because the school was just founded +and has no money whatsoever, so I installed a combined server (main +server, terminal services and workstation) in a VM on my personal +notebook, bridging the LTSP network interface to the ethernet port, +and then PXE-booted the Windows notebooks that were lying around from +it. I could use 8 clients without any performance issues, by using a +tiny little VM on a tiny little notebook. I think that's enough to say +that it rocks!</p> + +<p>Secondly, there are marketing reasons. Life's bad, and so no +politician will ever permit a setup described as "Debian, an universal +operating system, with some really cool educational tools" while they +will be jsut fine with "Skolelinux, a single-purpose solution for your +school network", even if both turn out to be the very same thing (yes, +this is unfair towards the Skolelinux project, and must not be taken +too seriously - you get the idea, anyway).</p> + +<p><strong>What do you see as the disadvantages of Skolelinux / Debian +Edu?</strong></p> + +<p>I have not been involved with Skolelinux long enough to really +answer this question in a fair way. Thus, please allow me to put it in +other words: "What do you expect from Skolelinux to keep liking it?" I +can list a few points about that:</p> -<p>To download the multiarch netinstall CD release you can use</p> <ul> - <li><a href="ftp://ftp.skolelinux.org/skolelinux-cd/wheezy/debian-edu~7.0+edu0~a1-CD.iso">ftp://ftp.skolelinux.org/skolelinux-cd/wheezy/debian-edu~7.0+edu0~a1-CD.iso</a></li> - <li><a href="http://ftp.skolelinux.org/skolelinux-cd/wheezy/debian-edu~7.0+edu0~a1-CD.iso">http://ftp.skolelinux.org/skolelinux-cd/wheezy/debian-edu~7.0+edu0~a1-CD.iso</a></li> - <li>rsync -avzP ftp.skolelinux.org::skolelinux-cd/wheezy/debian-edu~7.0+edu0~a1-CD.iso debian-edu~7.0+edu0~a1-CD.iso</li> + <li>always strive to get all things integrated into Debian upstream + <li>be open to discussion about changes and the like, even with newcomers + <li>be helpful at being helpful ;) </ul> -<p>The MD5SUM of this image is: 685ed76c1aa8e44b12d3fde21faf450b</p> - -<p>The SHA1SUM of this image is: 6c874de157024da13e115bab29c068080a11ec4c</p> - -<p><strong>How to report bugs</strong></p> - -<p><a href="http://wiki.debian.org/DebianEdu/HowTo/ReportBugs">http://wiki.debian.org/DebianEdu/HowTo/ReportBugs</a></p> - - - - - Debian, the Linux distribution of choice for LEGO designers? - http://people.skolelinux.org/pere/blog/Debian__the_Linux_distribution_of_choice_for_LEGO_designers_.html - http://people.skolelinux.org/pere/blog/Debian__the_Linux_distribution_of_choice_for_LEGO_designers_.html - Sat, 11 May 2013 20:30:00 +0200 - <P>In January, -<a href="http://people.skolelinux.org/pere/blog/New_IRC_channel_for_LEGO_designers_using_Debian.html">I -announced a</a> new <a href="irc://irc.debian.org/%23debian-lego">IRC -channel #debian-lego</a>, for those of us in the Debian and Linux -community interested in <a href="http://www.lego.com/">LEGO</a>, the -marvellous construction system from Denmark.

I have abandoned +all non-free software (except for firmware on my darned phone) this +year.</p> + +<p>I run Debian GNU/Linux on all PC systems I use. On that, I mostly +run text tools. I use +<a href="https://www.mirbsd.org/mksh.htm">mksh</a> as shell, +<a href="https://www.mirbsd.org/jupp.htm">jupp</a> as very advanced +text editor (I even got the developer to help me write a script/macro +based full-featured student management software with the two), +<a href="http://mcabber.com/">mcabber</a> for XMPP and +<a href="http://www.irssi.org/">irssi</a> for IRC. For that overly +coloured world called the WWW, I use +<a href="https://www.mozilla.org/en-US/firefox/new/">Iceweasel +(Firefox)</a>. Oh, and <a href="http://www.mutt.org/">mutt</a> for +e-mail.</p> + +<p>However, while I am personally aware of the fact that text tools +are more efficient and powerful than anything else, I also use (or at +least operate) some tools that are suitable to bring open source to +kids. One of these things is <a href="http://jappix.org/">Jappix</a>, +which I already introduced to some kids even before they got aware of +Facebook, making them see for themselves that they do not need +Facebook now ;).</p> + +<p><strong>Which strategy do you believe is the right one to use to +get schools to use free software?</strong></p> + +<p>Well, that's a two-sided thing. One side is what I believe, and one +side is what I have experienced.</p> + +<p>I believe that the right strategy is showing them the benefits. But +that won't work out as long as the acceptance of free alternatives +grows globally. What I mean is that if all the kids are almost forced +to use Windows, Facebook, Skype, you name it at home, they will not +see why they would want to use alternatives at school. I have seen +students take seat in front of a fully-functional, modern Debian +desktop that could do anything their Windows at home could do, and +they jsut refused to use it because "Linux sucks". It is something +that makes the council of our city spend around 600000 € to buy +software - not including hardware, mind you - for operating school +networks, and for installing a system that, as has been proved, does +not work. For those of you readers who are good at maths, have you +already found out how many lives could have been saved with that money +if we had instead used it to bring education to parts of the world +that need it? I have, and found it to be nothing less dramatic than +plain criminal.</p> + +<p>That said, the only feasible way appears to be the bottom up +method. We have to bring free software to kids and parents. I have +founded an association named +<a href="https://www.teckids.org">Teckids</a> here in Germany that does +just that. We organise several events for kids and adolescents in the +area of free and open source software, for example the +<a href="http://kids.froscon.org">FrogLabs</a>, which share staff with +Teckids and are the youth programme of +<a href="http://www.froscon.org">the Free and Open Source Software +Conference (FrOSCon)</a>. We do a lot more than most other conferences +- this year, we first offered the FrogLabs as a holiday camp for kids +aged 10 to 16. It was a huge success, with approx. 30 kids taking part +and learning with and about free software through a whole weekend. All +of us had a lot of fun, and the results were really exciting.</p> + +<p>Apart from that, we are preparing a campaign that is supposed to bring +the message of free alternatives to stuff kids use every day to them and +their parents, e.g. the use of Jabber / Jappix instead of Facebook and +Skype. To make that possible, we are planning to get together a team of +clever kids who understand very well what their peers need and can bring +it across to them. So we will have a peer-driven network of adolescents +who teach each other and collect feedback from the community of minors. +We then take that feedback and our own experience to work closely with +open source projects, such as Skolelinux or Jappix, at improving their +software in a way that makes it more and more attractive for the target +group. At least I hope that we will have good cooperation with +Skolelinux in the future ;)!</p> + +<p>So in conclusion, what I believe is that, if it weren't for the world +being so bad, it should be very clear to the political decision makers +that the only way to go nowadays is free software for various reasons, +but I have learnt that the only way that seems to work is bottom up.</p> + +<!-- + +> * Who should be interviewed with this questions in the future? + +That's probably the hardest question of them all, as I do not know the +community. However, I would be willing to do the following: + + <li>Run an interview with a German headteacher who is very open to + free software, and also prefers it, but cannot really use it because + of the decision makers above; + <li>Run interviews with some kids, both with and without previous + knowledge about free software + +If that is wanted, just let me know ;). + +--> - Narvik sparer minst 9 millioner på å bruke Skolelinux - http://people.skolelinux.org/pere/blog/Narvik_sparer_minst_9_millioner_p____bruke_Skolelinux.html - http://people.skolelinux.org/pere/blog/Narvik_sparer_minst_9_millioner_p____bruke_Skolelinux.html - Fri, 10 May 2013 18:30:00 +0200 - <p>I fjor sommer ble jeg -<a href="http://people.skolelinux.org/pere/blog/Gladoppslag_om_Skolelinux_i_avisen_Fremover.html">gledelig -overrasket</a> over et oppslag i avisen Fremover om Narvik kommunes -bruk av <a href="http://www.skolelinux.org/">Skolelinux</a>.

Dagbladet meldte for -eksempel at -«<a href="http://www.dagbladet.no/2012/11/22/nyheter/google_maps/google/utenriks/internett/24496816/">denne -øya finnes på kart, men ikke i virkeligheten</a>». Noe senere begynte -jeg å lese -<a href="http://www.gyldendal.no/Barn-og-ungdom/3-6-aar/Den-store-Ruffen-boken">historier -om Ruffen</a> til mine barn. Dette er historier om sjøormen Ruffen -skapt av Tor Åge Bringsværd, som starter med følgende beskrivelse:</p> - -<p><blockquote> -«Langt ute i havet ligger en mystisk øy. Den er bare synlig hver -tirsdag og fredag. Derfor står den ikke på noe kart. På denne øya -ligger et slott, og i slottet bor en gammel, fin sjøormfamilie.» -</blockquote></p> - -<p>Det virker åpenbart at Hr. Bringsværd tok feil når han trodde den -ikke var på noe kart, og at noen tydeligvis har vært i nærheten en -tirsdag eller en fredag og fått den med på et kart, mens -satellittbildene er tatt på noen av de fem andre dagene i uka og -dermed ikke ser øya. :)</p> - -<p>I følge -<a href="http://www.dagbladet.no/2012/12/03/nyheter/sandy_island/forskning/utenriks/24662158/">en -senere artikkel i Dagbladet</a> hevder Shaun Higgins, en forsker fra -New Zealand, at et hvalfangstskip fra 1876 er opprinnelsen til at -spøkelsesøya i det hele tatt havnet på kartet.

Den har stått og gått siden da, og har nå +ca. 28000 oppføringer. Jeg oppdaget da jeg tittet innom at noen +oppføringer var ikke blitt med, antagelig på grunn av at de fikk +tildelt sekvensnummer i Doffin en godt stund før de ble publisert, +slik at min nettsideskraper som fortsatte skrapingen der den slapp +sist ikke fikk dem med seg. Jeg har fikset litt slik at skraperen nå +ser litt tilbake i tid for å se om den har gått glipp av noen +oppføringer, og har skrapet på nytt fra midten av september 2013 og +fremover. Det bør dermed bli en mer komplett database for kommende +måneder. Hvis jeg får tid skal jeg forsøke å skrape "glemte" data fra +før midten av september 2013, men tør ikke garantere at det blir +prioritert med det første. </p> + +<p>Men målet med denne bloggposten er å vise hvordan denne +Doffin-databasen kan brukes og integreres med en RSS-leser, slik at en +kan la datamaskinen holde et øye med Doffin-annonseringer etter +nøkkelord.
