  24       <div class="date">10th November 2014</div>
  25       <div class="body"><p>The right to communicate with your friends and family in private,
  26 without anyone snooping, is a right every citicen have in a liberal
  27 democracy.  But this right is under serious attack these days.</p>
  28
  29 <p>A while back it occurred to me that one way to make the dragnet
  30 surveillance conducted by NSA, GCHQ, FRA and others (and confirmed by
  31 the whisleblower Snowden) more expensive for Internet email,
  32 is to deliver all email using SMTP via Tor.  Such SMTP option would be
  33 a nice addition to the FreedomBox project if we could send email
  34 between FreedomBox machines without leaking metadata about the emails
  35 to the people peeking on the wire.  I
  36 <a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2014-October/006493.html">proposed
  37 this on the FreedomBox project mailing list in October</a> and got a
  38 lot of useful feedback and suggestions.  It also became obvious to me
  39 that this was not a novel idea, as the same idea was tested and
  40 documented by Johannes Berg as early as 2006, and both
  41 <a href="https://github.com/pagekite/Mailpile/wiki/SMTorP">the
  42 Mailpile</a> and <a href="http://dee.su/cables">the Cables</a> systems
  43 propose a similar method / protocol to pass emails between users.</p>
  44
  45 <p>To implement such system one need to set up a Tor hidden service
  46 providing the SMTP protocol on port 25, and use email addresses
  47 looking like username@hidden-service-name.onion.  With such addresses
  48 the connections to port 25 on hidden-service-name.onion using Tor will
  49 go to the correct SMTP server.  To do this, one need to configure the
  50 Tor daemon to provide the hidden service and the mail server to accept
  51 emails for this .onion domain.  To learn more about Exim configuration
  52 in Debian and test the design provided by Johannes Berg in his FAQ, I
  53 set out yesterday to create a Debian package for making it trivial to
  54 set up such SMTP over Tor service based on Debian.  Getting it to work
  55 were fairly easy, and
  56 <a href="https://github.com/petterreinholdtsen/exim4-smtorp">the
  57 source code for the Debian package</a> is available from github.  I
  58 plan to move it into Debian if further testing prove this to be a
  59 useful approach.</p>
  60
  61 <p>If you want to test this, set up a blank Debian machine without any
  62 mail system installed (or run <tt>apt-get purge exim4-config</tt> to
  63 get rid of exim4).  Install tor, clone the git repository mentioned
  64 above, build the deb and install it on the machine.  Next, run
  65 <tt>/usr/lib/exim4-smtorp/setup-exim-hidden-service</tt> and follow
  66 the instructions to get the service up and running.  Restart tor and
  67 exim when it is done, and test mail delivery using swaks like
  68 this:</p>
  69
  70 <p><blockquote><pre>
  71 torsocks swaks --server dutlqrrmjhtfa3vp.onion \
  72   --to fbx@dutlqrrmjhtfa3vp.onion
  73 </pre></blockquote></p>
  74
  75 <p>This will test the SMTP delivery using tor.  Replace the email
  76 address with your own address to test your server. :)</p>
  77
  78 <p>The setup procedure is still to complex, and I hope it can be made
  79 easier and more automatic.  Especially the tor setup need more work.
  80 Also, the package include a tor-smtp tool written in C, but its task
  81 should probably be rewritten in some script language to make the deb
  82 architecture independent.  It would probably also make the code easier
  83 to review.  The tor-smtp tool currently need to listen on a socket for
  84 exim to talk to it and is started using xinetd.  It would be better if
  85 no daemon and no socket is needed.  I suspect it is possible to get
  86 exim to run a command line tool for delivery instead of talking to a
  87 socket, and hope to figure out how in a future version of this
  88 system.</p>
  89
  90 <p>Until I wipe my test machine, I can be reached using the
  91 <tt>fbx@dutlqrrmjhtfa3vp.onion</tt> mail address, deliverable over
  92 SMTorP. :)</p>

 142 About Debian Edu and Skolelinux
 143 ===============================
 144
 145 Debian Edu, also known as Skolelinux[2], is a Linux distribution based
 146 on Debian providing an out-of-the box environment of a completely
 147 configured school network. Immediately after installation a school
 148 server running all services needed for a school network is set up just
 149 waiting for users and machines being added via GOsa², a comfortable
 150 Web-UI. A netbooting environment is prepared using PXE, so after
 151 initial installation of the main server from CD or USB stick all other
 152 machines can be installed via the network.  The provided school server
 153 provides LDAP database and Kerberos authentication service,
 154 centralized home directories, DHCP server, web proxy and many other
 155 services.  The desktop contains more than 60 educational software
 156 packages[3] and more are available from the Debian archive, and
 157 schools can choose between KDE, Gnome, LXDE, Xfce and MATE desktop
 158 environment.

 300       <div class="body"><p>I spent last weekend at <a href="http://www.makercon.no/">Makercon
 301 Nordic</a>, a great conference and workshop for makers in Norway and
 302 the surrounding countries.  I had volunteered on behalf of the
 303 Norwegian Unix Users Group (NUUG) to video record the talks, and we
 304 had a great and exhausting time recording the entire day, two days in
 305 a row.  There were only two of us, Hans-Petter and me, and we used the
 306 regular video equipment for NUUG, with a
 307 <a href="http://dvswitch.alioth.debian.org/wiki/">dvswitch</a>, a
 308 camera and a VGA to DV convert box, and mixed video and slides
 309 live.</p>
 310
 311 <p>Hans-Petter did the post-processing, consisting of uploading the
 312 around 180 GiB of raw video to Youtube, and the result is

 332       <div class="date">22nd October 2014</div>
 333       <div class="body"><p>If you ever had to moderate a mailman list, like the ones on
 334 alioth.debian.org, you know the web interface is fairly slow to
 335 operate.  First you visit one web page, enter the moderation password
 336 and get a new page shown with a list of all the messages to moderate
 337 and various options for each email address.  This take a while for
 338 every list you moderate, and you need to do it regularly to do a good
 339 job as a list moderator.  But there is a quick alternative,
 340 <a href="http://heim.ifi.uio.no/kjetilho/hacks/#listadmin">the
 341 listadmin program</a>.  It allow you to check lists for new messages
 342 to moderate in a fraction of a second.  Here is a test run on two
 343 lists I recently took over:</p>
 344
 345 <p><blockquote><pre>
 346 % time listadmin xiph
 347 fetching data for pkg-xiph-commits@lists.alioth.debian.org ... nothing in queue
 348 fetching data for pkg-xiph-maint@lists.alioth.debian.org ... nothing in queue
 349
 350 real    0m1.709s
 351 user    0m0.232s
 352 sys     0m0.012s
 353 %
 354 </pre></blockquote></p>
 355
 356 <p>In 1.7 seconds I had checked two mailing lists and confirmed that
 357 there are no message in the moderation queue.  Every morning I
 358 currently moderate 68 mailman lists, and it normally take around two
 359 minutes.  When I took over the two pkg-xiph lists above a few days
 360 ago, there were 400 emails waiting in the moderator queue.  It took me
 361 less than 15 minutes to process them all using the listadmin
 362 program.</p>
 363
 364 <p>If you install
 365 <a href="https://tracker.debian.org/pkg/listadmin">the listadmin
 366 package</a> from Debian and create a file <tt>~/.listadmin.ini</tt>
 367 with content like this, the moderation task is a breeze:</p>
 368
 369 <p><blockquote><pre>
 370 username username@example.org
 371 spamlevel 23
 372 default discard
 373 discard_if_reason "Posting restricted to members only. Remove us from your mail list."
 374
 375 password secret
 376 adminurl https://{domain}/mailman/admindb/{list}
 377 mailman-list@lists.example.com
 378
 379 password hidden
 380 other-list@otherserver.example.org
 381 </pre></blockquote></p>
 382
 383 <p>There are other options to set as well.  Check the manual page to
 384 learn the details.</p>
 385
 386 <p>If you are forced to moderate lists on a mailman installation where
 387 the SSL certificate is self signed or not properly signed by a
 388 generally accepted signing authority, you can set a environment
 389 variable when calling listadmin to disable SSL verification:</p>
 390
 391 <p><blockquote><pre>
 392 PERL_LWP_SSL_VERIFY_HOSTNAME=0 listadmin
 393 </pre></blockquote></p>
 394
 395 <p>If you want to moderate a subset of the lists you take care of, you
 396 can provide an argument to the listadmin script like I do in the
 397 initial screen dump (the xiph argument).  Using an argument, only
 398 lists matching the argument string will be processed.  This make it
 399 quick to accept messages if you notice the moderation request in your
 400 email.</p>
 401
 402 <p>Without the listadmin program, I would never be the moderator of 68
 403 mailing lists, as I simply do not have time to spend on that if the
 404 process was any slower. The listadmin program have saved me hours of
 405 time I could spend elsewhere over the years.  It truly is nice free
 406 software.</p>

 411
 412 <p>Update 2014-10-27: Added missing 'username' statement in
 413 configuration example.  Also, I've been told that the
 414 PERL_LWP_SSL_VERIFY_HOSTNAME=0 setting do not work for everyone.  Not

 429       <div class="date">17th October 2014</div>
 430       <div class="body"><p>When PXE installing laptops with Debian, I often run into the
 431 problem that the WiFi card require some firmware to work properly.
 432 And it has been a pain to fix this using preseeding in Debian.
 433 Normally something more is needed.  But thanks to
 434 <a href="https://packages.qa.debian.org/i/isenkram.html">my isenkram
 435 package</a> and its recent tasksel extension, it has now become easy
 436 to do this using simple preseeding.</p>
 437
 438 <p>The isenkram-cli package provide tasksel tasks which will install
 439 firmware for the hardware found in the machine (actually, requested by
 440 the kernel modules for the hardware).  (It can also install user space
 441 programs supporting the hardware detected, but that is not the focus
 442 of this story.)</p>
 443
 444 <p>To get this working in the default installation, two preeseding
 445 values are needed.  First, the isenkram-cli package must be installed
 446 into the target chroot (aka the hard drive) before tasksel is executed
 447 in the pkgsel step of the debian-installer system.  This is done by
 448 preseeding the base-installer/includes debconf value to include the
 449 isenkram-cli package.  The package name is next passed to debootstrap
 450 for installation.  With the isenkram-cli package in place, tasksel
 451 will automatically use the isenkram tasks to detect hardware specific
 452 packages for the machine being installed and install them, because
 453 isenkram-cli contain tasksel tasks.</p>
 454
 455 <p>Second, one need to enable the non-free APT repository, because
 456 most firmware unfortunately is non-free.  This is done by preseeding
 457 the apt-mirror-setup step.  This is unfortunate, but for a lot of
 458 hardware it is the only option in Debian.</p>
 459
 460 <p>The end result is two lines needed in your preseeding file to get
 461 firmware installed automatically by the installer:</p>
 462
 463 <p><blockquote><pre>
 464 base-installer base-installer/includes string isenkram-cli
 465 apt-mirror-setup apt-setup/non-free boolean true
 466 </pre></blockquote></p>
 467
 468 <p>The current version of isenkram-cli in testing/jessie will install
 469 both firmware and user space packages when using this method.  It also
 470 do not work well, so use version 0.15 or later.  Installing both
 471 firmware and user space packages might give you a bit more than you
 472 want, so I decided to split the tasksel task in two, one for firmware
 473 and one for user space programs.  The firmware task is enabled by
 474 default, while the one for user space programs is not.  This split is
 475 implemented in the package currently in unstable.</p>
 476
 477 <p>If you decide to give this a go, please let me know (via email) how
 478 this recipe work for you. :)</p>
 479
 480 <p>So, I bet you are wondering, how can this work.  First and
 481 foremost, it work because tasksel is modular, and driven by whatever
 482 files it find in /usr/lib/tasksel/ and /usr/share/tasksel/.  So the
 483 isenkram-cli package place two files for tasksel to find.  First there
 484 is the task description file (/usr/share/tasksel/descs/isenkram.desc):</p>
 485
 486 <p><blockquote><pre>
 487 Task: isenkram-packages
 488 Section: hardware
 489 Description: Hardware specific packages (autodetected by isenkram)
 490  Based on the detected hardware various hardware specific packages are
 491  proposed.
 492 Test-new-install: show show
 493 Relevance: 8
 494 Packages: for-current-hardware
 495
 496 Task: isenkram-firmware
 497 Section: hardware
 498 Description: Hardware specific firmware packages (autodetected by isenkram)
 499  Based on the detected hardware various hardware specific firmware
 500  packages are proposed.
 501 Test-new-install: mark show
 502 Relevance: 8
 503 Packages: for-current-hardware-firmware
 504 </pre></blockquote></p>
 505
 506 <p>The key parts are Test-new-install which indicate how the task
 507 should be handled and the Packages line referencing to a script in
 508 /usr/lib/tasksel/packages/.  The scripts use other scripts to get a
 509 list of packages to install.  The for-current-hardware-firmware script
 510 look like this to list relevant firmware for the machine:
 511
 512 <p><blockquote><pre>
 513 #!/bin/sh
 514 #
 515 PATH=/usr/sbin:$PATH
 516 export PATH
 517 isenkram-autoinstall-firmware -l
 518 </pre></blockquote></p>
 519
 520 <p>With those two pieces in place, the firmware is installed by
 521 tasksel during the normal d-i run. :)</p>
 522
 523 <p>If you want to test what tasksel will install when isenkram-cli is
 524 installed, run <tt>DEBIAN_PRIORITY=critical tasksel --test
 525 --new-install</tt> to get the list of packages that tasksel would
 526 install.</p>
 527
 528 <p><a href="https://wiki.debian.org/DebianEdu/">Debian Edu</a> will be
 529 pilots in testing this feature, as isenkram is used there now to
 530 install firmware, replacing the earlier scripts.</p>

 618       <div class="date">26th September 2014</div>
 619       <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
 620 project</a> provide a Linux solution for schools, including a
 621 powerful desktop with education software, a central server providing
 622 web pages, user database, user home directories, central login and PXE
 623 boot of both  clients without disk and the installation to install Debian
 624 Edu on machines with disk (and a few other services perhaps to small
 625 to mention here).  We in the Debian Edu team are currently working on
 626 the Jessie based version, trying to get everything in shape before the
 627 freeze, to avoid having to maintain our own package repository in the
 628 future.  The
 629 <a href="https://wiki.debian.org/DebianEdu/Status/Jessie">current
 630 status</a> can be seen on the Debian wiki, and there is still heaps of
 631 work left.  Some fatal problems block testing, breaking the installer,
 632 but it is possible to work around these to get anyway.  Here is a
 633 recipe on how to get the installation limping along.</p>
 634
 635 <p>First, download the test ISO via
 636 <a href="ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">ftp</a>,
 637 <a href="http://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">http</a>
 638 or rsync (use
 639 ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso).
 640 The ISO build was broken on Tuesday, so we do not get a new ISO every
 641 12 hours or so, but thankfully the ISO we already got we are able to
 642 install with some tweaking.</p>
 643
 644 <p>When you get to the Debian Edu profile question, go to tty2
 645 (use Alt-Ctrl-F2), run</p>
 646
 647 <p><blockquote><pre>
 648 nano /usr/bin/edu-eatmydata-install
 649 </pre></blockquote></p>
 650
 651 <p>and add 'exit 0' as the second line, disabling the eatmydata
 652 optimization.  Return to the installation, select the profile you want
 653 and continue.  Without this change, exim4-config will fail to install
 654 due to a known bug in eatmydata.</p>
 655
 656 <p>When you get the grub question at the end, answer /dev/sda (or if
 657 this do not work, figure out what your correct value would be.  All my
 658 test machines need /dev/sda, so I have no advice if it do not fit
 659 your need.</p>
 660
 661 <p>If you installed a profile including a graphical desktop, log in as
 662 root after the initial boot from hard drive, and install the
 663 education-desktop-XXX metapackage.  XXX can be kde, gnome, lxde, xfce
 664 or mate.  If you want several desktop options, install more than one
 665 metapackage.  Once this is done, reboot and you should have a working
 666 graphical login screen.  This workaround should no longer be needed
 667 once the education-tasks package version 1.801 enter testing in two
 668 days.</p>
 669
 670 <p>I believe the ISO build will start working on two days when the new
 671 tasksel package enter testing and Steve McIntyre get a chance to
 672 update the debian-cd git repository.  The eatmydata, grub and desktop
 673 issues are already fixed in unstable and testing, and should show up
 674 on the ISO as soon as the ISO build start working again.  Well the
 675 eatmydata optimization is really just disabled.  The proper fix
 676 require an upload by the eatmydata maintainer applying the patch
 677 provided in bug <a href="https://bugs.debian.org/702711">#702711</a>.
 678 The rest have proper fixes in unstable.</p>
 679
 680 <p>I hope this get you going with the installation testing, as we are
 681 quickly running out of time trying to get our Jessie based
 682 installation ready before the distribution freeze in a month.</p>

 697       <div class="body"><p>I use the <a href="https://sourceforge.net/p/lsdvd/">lsdvd tool</a>
 698 to handle my fairly large DVD collection.  It is a nice command line
 699 tool to get details about a DVD, like title, tracks, track length,
 700 etc, in XML, Perl or human readable format.  But lsdvd have not seen
 701 any new development since 2006 and had a few irritating bugs affecting
 702 its use with some DVDs.  Upstream seemed to be dead, and in January I
 703 sent a small probe asking for a version control repository for the
 704 project, without any reply.  But I use it regularly and would like to
 705 get <a href="https://packages.qa.debian.org/lsdvd">an updated version
 706 into Debian</a>.  So two weeks ago I tried harder to get in touch with
 707 the project admin, and after getting a reply from him explaining that
 708 he was no longer interested in the project, I asked if I could take
 709 over.  And yesterday, I became project admin.</p>
 710
 711 <p>I've been in touch with a Gentoo developer and the Debian
 712 maintainer interested in joining forces to maintain the upstream
 713 project, and I hope we can get a new release out fairly quickly,
 714 collecting the patches spread around on the internet into on place.
 715 I've added the relevant Debian patches to the freshly created git
 716 repository, and expect the Gentoo patches to make it too.  If you got
 717 a DVD collection and care about command line tools, check out
 718 <a href="https://sourceforge.net/p/lsdvd/git/ci/master/tree/">the git source</a> and join

 735       <div class="body"><p>Rundt omkring i Oslo og Østlandsområdet henger det bokser over
 736 veiene som jeg har lurt på hva gjør.  De har ut fra plassering og
 737 vinkling sett ut som bokser som sniffer ut et eller annet fra
 738 forbipasserende trafikk, men det har vært uklart for meg hva det er de
 739 leser av.  Her om dagen tok jeg bilde av en slik boks som henger under

 745 <p>Boksen er tydelig merket «Kapsch >>>», logoen til
 746 <a href="http://www.kapsch.net/">det sveitsiske selskapet Kapsch</a> som
 747 blant annet lager sensorsystemer for veitrafikk.  Men de lager mye
 748 forskjellig, og jeg kjente ikke igjen boksen på utseendet etter en
 749 kjapp titt på produktlista til selskapet.</p>
 750
 751 <p>I og med at boksen henger over veien E16, en riksvei vedlikeholdt
 752 av Statens Vegvesen, så antok jeg at det burde være mulig å bruke
 753 REST-API-et som gir tilgang til vegvesenets database over veier,
 754 skilter og annet veirelatert til å finne ut hva i alle dager dette
 755 kunne være.  De har både

 758 <a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/sok">et
 759 søk</a>, der en kan søke etter ulike typer oppføringer innen for et
 760 gitt geografisk område.  Jeg laget et enkelt shell-script for å hente
 761 ut antall av en gitt type innenfor området skibrua dekker, og listet
 762 opp navnet på typene som ble funnet.  Orket ikke slå opp hvordan
 763 URL-koding av aktuelle strenger kunne gjøres mer generisk, og brukte
 764 en stygg sed-linje i stedet.</p>

 936
 937 <p>Av disse ser ID 775 og 862 mest relevant ut.  ID 775 antar jeg
 938 refererer til fotoboksen som står like ved brua, mens
 939 «Reisetidsregistreringspunkt» kanskje kan være boksen som henger der.
 940 Hvordan finner jeg så ut hva dette kan være for noe.  En titt på
 941 <a href="http://labs.vegdata.no/nvdb-datakatalog/862-Reisetidsregistreringspunkt/">datakatalogsiden
 942 for ID 862/Reisetidsregistreringspunkt</a> viser at det er finnes 53
 943 slike målere i Norge, og hvor de er plassert, men gir ellers få
 944 detaljer.  Det er plassert 40 på østlandet og 13 i Trondheimsregionen.
 945 Men siden nevner «AutoPASS», og hvis en slår opp oppføringen på
 946 Sollihøgda nevner den «Ciber AS» som ID for eksternt system.  (Kan det
 947 være snakk om
 948 <a href="http://www.proff.no/selskap/ciber-norge-as/oslo/internettdesign-og-programmering/Z0I3KMF4/">Ciber
 949 Norge AS</a>, et selskap eid av Ciber Europe Bv?)  Et nettsøk på
 950  «Ciber AS autopass» fører meg til en artikkel fra NRK Trøndelag i
 951  2013 med tittel
 952 «<a href="http://www.nrk.no/trondelag/sjekk-dette-hvis-du-vil-unnga-ko-1.11327947">Sjekk
 953 dette hvis du vil unngå kø</a>».  Artikkelen henviser til vegvesenets
 954 nettside
 955 <a href="http://www.reisetider.no/reisetid/forside.html">reisetider.no</a>
 956 som har en
 957 <a href="http://www.reisetider.no/reisetid/omrade.html?omrade=5">kartside
 958 for Østlandet</a> som viser at det måles mellom Sandvika og Sollihøgda.
 959 Det kan dermed se ut til at jeg har funnet ut hva boksene gjør.</p>
 960
 961 <p>Hvis det stemmer, så er dette bokser som leser av AutoPASS-ID-en
 962 til alle passerende biler med AutoPASS-brikke, og dermed gjør det mulig
 963 for de som kontrollerer boksene å holde rede på hvor en gitt bil er
 964 når den passerte et slikt målepunkt.  NRK-artikkelen forteller at
 965 denne informasjonen i dag kun brukes til å koble to
 966 AutoPASS-brikkepasseringer passeringer sammen for å beregne
 967 reisetiden, og at bruken er godkjent av Datatilsynet.  Det er desverre
 968 ikke mulig for en sjåfør som passerer under en slik boks å kontrollere
 969 at AutoPASS-ID-en kun brukes til dette i dag og i fremtiden.</p>
 970
 971 <p>I tillegg til denne type AutoPASS-sniffere vet jeg at det også
 972 finnes mange automatiske stasjoner som tar betalt pr. passering (aka
 973 bomstasjoner), og der lagres informasjon om tid, sted og bilnummer i
 974 10 år.  Finnes det andre slike sniffere plassert ut på veiene?</p>
 975
 976 <p>Personlig har jeg valgt å ikke bruke AutoPASS-brikke, for å gjøre
 977 det vanskeligere og mer kostbart for de som vil invadere privatsfæren
 978 og holde rede på hvor bilen min beveger seg til enhver tid.  Jeg håper
 979 flere vil gjøre det samme, selv om det gir litt høyere private
 980 utgifter (dyrere bompassering).  Vern om privatsfæren koster i disse
 981 dager.</p>
 982
 983 <p>Takk til Jan Kristian Jensen i Statens Vegvesen for tips om
 984 dokumentasjon på vegvesenets REST-API.</p>
