  24       <div class="date">10th September 2013</div>
  25       <div class="body"><p>I was introduced to the
  26 <a href="http://www.freedomboxfoundation.org/">Freedombox project</a>
  27 in 2010, when Eben Moglen presented his vision about serving the need
  28 of non-technical people to keep their personal information private and
  29 within the legal protection of their own homes.  The idea is to give
  30 people back the power over their network and machines, and return
  31 Internet back to its intended peer-to-peer architecture.  Instead of
  32 depending on a central service, the Freedombox will give everyone
  33 control over their own basic infrastructure.</p>
  34
  35 <p>I've intended to join the effort since then, but other tasks have
  36 taken priority.  But this summers nasty news about the misuse of trust
  37 and privilege exercised by the "western" intelligence gathering
  38 communities increased my eagerness to contribute to a point where I
  39 actually started working on the project a while back.</p>
  40
  41 <p>The <a href="https://alioth.debian.org/projects/freedombox/">initial
  42 Debian initiative</a> based on the vision from Eben Moglen, is to
  43 create a simple and cheap Debian based appliance that anyone can hook
  44 up in their home and get access to secure and private services and
  45 communication.  The initial deployment platform have been the
  46 <a href="http://www.globalscaletechnologies.com/t-dreamplugdetails.aspx">Dreamplug</a>,
  47 which is a piece of hardware I do not own.  So to be able to test what
  48 the current Freedombox setup, I had to come up with a way to install
  49 it on some hardware I do got access to.  I have rewritten the
  50 <a href="https://github.com/NickDaly/freedom-maker">freedom-maker</a>
  51 image build framework to use .deb packages instead of only copying
  52 setup into the boot images, and thanks to this rewrite I am able to
  53 set up any machine supported by Debian Wheezy as a Freedombox, using
  54 the previously mentioned deb (and a few support debs for packages
  55 missing in Debian).</p>
  56
  57 <p>The current Freedombox setup consist of a set of bootstrapping
  58 scripts
  59 (<a href="https://github.com/petterreinholdtsen/freedombox-setup">freedombox-setup</a>),
  60 and a administrative web interface
  61 (<a href="https://github.com/NickDaly/Plinth">plinth</a> + exmachina +
  62 withsqlite), as well as a privacy enhancing proxy based on
  63 <a href="http://packages.qa.debian.org/privoxy">privoxy</a>
  64 (freedombox-privoxy).  There is also a web/javascript based XMPP
  65 client (<a href="http://packages.qa.debian.org/jwchat">jwchat</a>)
  66 trying (unsuccessfully so far) to talk to the XMPP server
  67 (<a href="http://packages.qa.debian.org/ejabberd">ejabberd</a>).  The
  68 web interface is pluggable, and the goal is to use it to enable OpenID
  69 services, mesh network connectivity, use of TOR, etc, etc.  Not much of
  70 this is really working yet, see
  71 <a href="https://github.com/NickDaly/freedombox-todos/blob/master/TODO">the
  72 project TODO</a> for links to GIT repositories.  Most of the code is
  73 on github at the moment.  The HTTP proxy is operational out of the
  74 box, and the admin web interface can be used to add/remove plinth
  75 users.  I've not been able to do anything else with it so far, but
  76 know there are several branches spread around github and other places
  77 with lots of half baked features.</p>
  78
  79 <p>Anyway, if you want to have a look at the current stat, the
  80 following recipes should work to give you a test machine to poke
  81 at.</p>
  82
  83 <p><strong>Debian Wheezy amd64</strong></p>
  84
  85 <ol>
  86
  87 <li>Fetch normal Debian Wheezy installation ISO.</li>
  88 <li>Boot from it, either as CD or USB stick.</li>
  89 <li><p>Press [tab] on the boot prompt and add this as a boot argument
  90 to the Debian installer:<p>
  91 <pre>url=http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat</pre></li>
  92
  93 <li>Answer the few language/region/password questions and pick disk to
  94 install on.</li>
  95
  96 <li>When the installation is finished and the machine have rebooted a
  97 few times, your Freedombox is ready for testing.</li>
  98
  99 </ol>
 100
 101 <p><strong>Raspberry Pi Raspbian</strong></p>
 102
 103 <ol>
 104
 105 <li>Fetch a Raspbian SD card image, create SD card.</li>
 106 <li>Boot from SD card, extend file system to fill the card completely.</li>
 107 <li><p>Log in and add this to /etc/sources.list:</p>
 108 <pre>
 109 deb http://www.reinholdtsen.name/freedombox wheezy main
 110 </pre></li>
 111 <li><p>Run this as root:</p>
 112 <pre>
 113 wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
 114    apt-key add -
 115 apt-get update
 116 apt-get install freedombox-setup
 117 /usr/lib/freedombox/setup
 118 </pre></li>
 119 <li>Reboot into your freshly created Freedombox.</li>
 120
 121 </ol>
 122
 123 <p>You can test it on other architectures too, but because the
 124 freedombox-privoxy package is binary, it will only work as intended on
 125 the architectures where I have had time to build the binary and put it
 126 in my APT repository.  But do not let this stop you.  It is only a
 127 short "<tt>apt-get source -b freedombox-privoxy</tt>" away. :)</p>
 128
 129 <p>Note that by default Freedombox is a DHCP server on the
 130 192.168.1.0/24 subnet, so if this is your subnet be careful and turn
 131 off the DHCP server by running "<tt>update-rc.d isc-dhcp-server
 132 disable</tt>" as root.</p>
 133
 134 <p>Please let me know if this work for you, or if you have any
 135 problems.  We gather on the IRC channel
 136 <a href="irc://irc.debian.org:6667/%23freedombox">#freedombox</a> on
 137 irc.debian.org and the
 138 <a href="http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss">project
 139 mailing list</a>.</p>
 140
 141 <p>Once you get your freedombox operational, you can visit
 142 <tt>http://your-host-name:8001/</tt> to see the state of the plint
 143 welcome screen (dead end - do not be surprised if you are unable to
 144 get past it), and next visit <tt>http://your-host-name:8001/help/</tt>
 145 to look at the rest of plinth.  The default user is 'admin' and the
 146 default password is 'secret'.</p>

 160       <div class="date"> 8th September 2013</div>
 161       <div class="body"><p>I 2011 raderte et stortingsflertall bestående av Høyre og
 162 Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske
 163 folk.  Det ble vedtatt at det skulle registreres og lagres i et halvt
 164 år hvor alle som bærer på en mobiltelefon befinner seg, hvem de
 165 snakker med og hvor lenge de snakket sammen.  Det skal også
 166 registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost
 167 til, og hvilke nett-tjenere en besøkte.  Saken er kjent som
 168 <a href="http://beta.holderdeord.no/issues/innfore-datalagringsdirektivet">Datalagringsdirektivet
 169 (DLD)</a>, og innebærer at alle innbyggerne og andre innenfor Norges
 170 grenser overvåkes døgnet rundt.  Det ble i praksis innført brev og
 171 besøkskontroll av hele befolkningen.  Rapporter fra de landene som
 172 allerede har innført slik total lagring av borgernes
 173 kommunikasjonsmønstre forteller at det ikke hjelper i
 174 kriminalitetsbekjempelsen.  Den norske prislappen blir mange hundre
 175 millioner, uten at det ser ut til å bidra positivt til politiets
 176 arbeide.  Jeg synes flere hundre millioner i stedet burde vært brukt
 177 på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen.
 178 Se mer på
 179 <a href="http://no.wikipedia.org/wiki/Datalagringsdirektivet">Wikipedia</a>
 180 og <a href="http://www.uhuru.biz/?cat=84">Jon Wessel-Aas</a>.</p>
 181
 182 <p>Hva er problemet, tenkter du kanskje?  Et åpenbart problem er at
 183 medienes kildevern i praksis blir radert ut.  Den innsamlede
 184 informasjonen gjør det mulig å finne ut hvem som har snakket med
 185 journalister på telefon, SMS og epost, og hvem som har vært i nærheten
 186 av journalister så sant begge bar med seg en telefon.  Et annet er at
 187 advokatvernet blir sterkt redusert, der politiet kan finne ut hvem
 188 som har snakket med en advokat når, eller vært i møter en med advokat.
 189 Et tredje er at svært personlig informasjon kan avledes fra hvilke
 190 nettsteder en har besøkt.  Har en besøkt hivnorge.no,
 191 swingersnorge.com eller andre sider som kan brukes til avlede
 192 interesser som hører til privatsfæren, vil denne informasjonen være
 193 tilgjengelig takket være datalagringsdirektivet.</p>
 194
 195 <p>De fleste partiene var mot, kun to partier stemte for.  Høyre og
 196 Arbeiderpartiet.  Og både Høyre og Arbeiderpartiet i Oslo har
 197 DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre
 198 fylkene).  Det er dermed helt uaktuelt for meg å stemme på disse
 199 partiene.  Her er oversikten over partienes valglister i Oslo, med
 200 informasjon om hvem som stemte hva i første DLD-votering i Stortinget,
 201 basert på informasjon fra mine venner i

 445       <div class="body"><p>The second wheezy based beta release of Debian Edu was wrapped up
 446 today, slightly delayed because of some bugs in the initial Windows
 447 integration fixes .  This is the release announcement:</p>
 448
 449 <p><strong>New features for Debian Edu 7.1+edu0~b1 released 2013-08-22</strong></p>
 450
 451 <p>These are the release notes for Debian Edu / Skolelinux
 452 7.1+edu0~b1, based on Debian with codename "Wheezy".</p>
 453
 454 <p><strong>About Debian Edu and Skolelinux</strong></p>
 455
 456 <p><a href="http://www.skolelinux.org/">Debian Edu, also known as
 457 Skolelinux</a>, is a Linux distribution based on Debian providing an
 458 out-of-the box environment of a completely configured school
 459 network. Immediately after installation a school server running all
 460 services needed for a school network is set up just waiting for users
 461 and machines being added via GOsa², a comfortable Web-UI. A netbooting
 462 environment is prepared using PXE, so after initial installation of
 463 the main server from CD or USB stick all other machines can be
 464 installed via the network. The provided school server provides LDAP
 465 database and Kerberos authentication service, centralized home
 466 directories, DHCP server, web proxy and many other services. The
 467 desktop contains
 468 <a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
 469 than 60 educational software packages</a> and more are available from
 470 the Debian archive, and schools can choose between KDE, Gnome, LXDE
 471 and Xfce desktop environment.</p>
 472
 473 <p>This is the sixth test release based on Debian Wheezy. Basically this
 474 is an updated and slightly improved version compared to the Squeeze
 475 release.</p>
 476
 477 <p>ALERT: Alpha based installations should reinstall or downgrade the
 478 versions of gosa and libpam-mklocaluser to the ones used in this beta
 479 release. Both alpha and beta0 based installations should reinstall or
 480 deal with gosa.conf manually; there are two options: (1) Keep
 481 gosa.conf and edit this file as outlined
 482 <a href="http://lists.debian.org/debian-edu/2013/08/msg00127.html">on
 483 the mailing list</a>. (2) Accept the new version of gosa.conf and
 484 replace both contained admin password placeholders with the password
 485 hashes found in the old one (backup copy!). In both cases every user
 486 need to change their their password to make sure a password is set for
 487 CIFS access to their home directory.</p>
 488
 489 <p><strong>Software updates</strong></p>
 490
 491 <ul>
 492
 493 <li>Added ssh askpass packages to default installation, to ensure ssh
 494     work also without a attached tty.</li>
 495 <li>Add the command-not-found package to the default installation to
 496     make it easier to figure out where to find missing command line
 497     tools. Please note, that the command 'update-command-not-found'
 498     has to be run as root to actually make it useful (internet access
 499     required).</li>
 500
 501 </ul>
 502
 503 <p><strong>Other changes</strong></p>
 504
 505 <ul>
 506
 507 <li>Adjusted the USB stick ISO image build to include every tool
 508 needed for desktop=xfce installations.</li>
 509 <li>Adjust thin-client-server task to work when installing from USB
 510 stick ISO image.</li>
 511 <li>Made new grub artwork (changed png from indexed to RGB format).</li>
 512 <li>Minor cleanup in the CUPS setup.</li>
 513 <li>Make sure that bootstrapping of the Samba domain really happens
 514     during installation of the main server and adjust SID handling to
 515     cope with this.</li>
 516 <li>Make Samba passwords changeable (again) via GOsa².</li>
 517 <li>Fix generation of LM and NT password hashes via GOsa² to avoid
 518     empty password hashes.</li>
 519 <li>Adapted Samba machine domain joining to latest change in the
 520     smbldap-tools Perl package, fixing bugs blocking Windows machines
 521     from joining the Samba domain.</li>

 524
 525 <p><strong>Known issues</strong></p>
 526
 527 <ul>

 583       <div class="date">18th August 2013</div>
 584       <div class="body"><p>Earlier, I reported about
 585 <a href="http://people.skolelinux.org/pere/blog/How_to_fix_a_Thinkpad_X230_with_a_broken_180_GB_SSD_disk.html">my
 586 problems using an Intel SSD 520 Series 180 GB disk</a>.  Friday I was
 587 told by IBM that the original disk should be thrown away.  And as
 588 there no longer was a problem if I bricked the firmware, I decided
 589 today to try to install Intel firmware to replace the Lenovo firmware
 590 currently on the disk.</p>
 591
 592 <p>I searched the Intel site for firmware, and found
 593 <a href="https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3472&DwnldID=18363&ProductFamily=Solid-State+Drives+and+Caching&ProductLine=Intel%c2%ae+High+Performance+Solid-State+Drive&ProductProduct=Intel%c2%ae+SSD+520+Series+(180GB%2c+2.5in+SATA+6Gb%2fs%2c+25nm%2c+MLC)&lang=eng">issdfut_2.0.4.iso</a>
 594 (aka Intel SATA Solid-State Drive Firmware Update Tool) which
 595 according to the site should contain the latest firmware for SSD
 596 disks.  I inserted the broken disk in one of my spare laptops and
 597 booted the ISO from a USB stick.  The disk was recognized, but the
 598 program claimed the newest firmware already were installed and refused
 599 to insert any Intel firmware.  So no change, and the disk is still
 600 unable to handle write load. :( I guess the only way to get them
 601 working would be if Lenovo releases new firmware.  No idea how likely
 602 that is.  Anyway, just blogging about this test for completeness.  I
 603 got a working Samsung disk, and see no point in spending more time on
 604 the broken disks.</p>

 618       <div class="date"> 2nd August 2013</div>
 619       <div class="body"><p>It has been a while since my last update.  Since last summer, I
 620 have worked on a Norwegian
 621 <a href="http://www.docbook.org/">docbook</a> version of the 2004 book
 622 <a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig,
 623 to get a Norwegian text explaining the problems with the copyright
 624 law.  Yesterday, I finally broken the 90% mark, when counting the
 625 number of strings to translate.  Due to real life constraints, I have
 626 not had time to work on it since March, but when the summer broke out,
 627 I found time to work on it again.  Still lots of work left, but the
 628 first draft is nearing completion.  I created a graph to show the
 629 progress of the translation:</p>
 630
 631 <p><img width="80%" align="center" src="https://github.com/petterreinholdtsen/free-culture-lessig/raw/master/progress.png"></p>
 632
 633 <p>When the first draft is done, the translated text need to be
 634 proof read, and the remaining formatting problems with images and SVG
 635 drawings need to be fixed.  There are probably also some index entries
 636 missing that need to be added.  This can be done by comparing the
 637 index entries listed in the SiSU version of the book, or comparing the
 638 English docbook version with the paper version.  Last, the colophon
 639 page with ISBN numbers etc need to be wrapped up before the release is
 640 done.  I should also figure out how to get correct Norwegian sorting
 641 of the index pages.  All docbook tools I have tried so far (xmlto,
 642 docbook-xsl, dblatex) get the order of symbols and the special
 643 Norwegian letters ÆØÅ wrong.</p>
 644
 645 <p>There is still need for translators and people with docbook
 646 knowledge, to be able to get a good looking book (I still struggle
 647 with dblatex, xmlto and docbook-xsl) as well as to do the draft
 648 translation and proof reading.  And I would like the figures to be
 649 redrawn as SVGs to make it easy to translate them.  Any SVG master
 650 around?  There are also some legal terms that are unfamiliar to me.
 651 If you want to help, please get in touch with me, and check out the
 652 project files currently available from
 653 <a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>.</p>
 654
 655 <p>If you are curious what the translated book currently look like,
 656 the updated
 657 <a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.pdf?raw=true">PDF</a>
 658 and
 659 <a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.epub?raw=true">EPUB</a>
 660 are published on github.  The HTML version is published as well, but
 661 github hand it out with MIME type text/plain, confusing browsers, so I
 662 saw no point in linking to that version.</p>

 686 <p><strong>About Debian Edu and Skolelinux</strong></p>
 687
 688 <p><a href="http://www.skolelinux.org/">Debian Edu, also known as
 689 Skolelinux</a>, is a Linux distribution based on Debian providing an
 690 out-of-the box environment of a completely configured school
 691 network. Immediately after installation a school server running all
 692 services needed for a school network is set up just waiting for users
 693 and machines being added via GOsa², a comfortable Web-UI. A netbooting
 694 environment is prepared using PXE, so after initial installation of
 695 the main server from CD, DVD or USB stick all other machines can be
 696 installed via the network. The provided school server provides LDAP
 697 database and Kerberos authentication service, centralized home
 698 directories, DHCP server, web proxy and many other services. The
 699 desktop contains
 700 <a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
 701 than 60 educational software packages</a> and more are available from
 702 the Debian archive, and schools can choose between KDE, Gnome, LXDE
 703 and Xfce desktop environment.</p>
 704
 705 <p>This is the fifth test release based on Debian Wheezy. Basically
 706 this is an updated and slightly improved version compared to the
 707 Squeeze release.</p>
 708
 709 <p>ALERT: Alpha based installations should reinstall or downgrade the
 710 versions of gosa and libpam-mklocaluser to the ones used in this beta
 711 release.</p>
 712
 713 <p><strong>Software updates</strong></p>
 714
 715 <ul>
 716
 717 <li>Switched roaming workstation profiles from wicd to network-manager
 718    for network configuration, as wicd didn't work any more.</li>
 719 <li>Changed version numbers of patched gosa and libpam-mklocaluser
 720    packages to make sure our locally patched versions will be replaced
 721    by the official packages when they are released from Debian. Those
 722    installing alpha version need to reinstall or manually downgrade gosa
 723    and libpam-mklocaluser.</li>
 724 <li>Added bluetooth tools to the default desktop (bluedevil, blueman).</li>
 725 <li>Added tools for sharing the desktop on KDE (krdc, krfb).</li>
 726 <li>Added valgrind to the default installation for easier debugging of
 727    crash bugs.</li>
 728
 729 </ul>
 730
 731 <p><strong>Other changes</strong></p>
 732
 733 <ul>
 734
 735 <li>Fixed artwork package to work with gnome, no longer break
 736    desktop=gnome installations.</li>
 737 <li>Adjusted installer to now work when forced to use a proxy with the
 738    netinst CD.</li>
 739 <li>Fixed code detecting and setting/loading hardware specific
 740    setup/firmware to work more robust out of the box.</li>
 741 <li>Adjusted Kerberos setup to detect realm and server settings at
 742    install time instead of dynamically at run time. This avoid a crash
 743    with krb5-auth-dialog on diskless workstations without a DNS name.</li>
 744 <li>Worked around misfeature in network-manager not calling the dhclient
 745    exit hooks, causing automatic proxy configuration and automatic host
 746    name setting at run time to work again.</li>
 747 <li>Fixed feature setting the default Iceweasel start page from URL
 748    fetched from LDAP, to allow schools to set the global default by
 749    updating the dc=skole,dc=skolelinux,dc=no LDAP object.</li>
 750 <li>Changed default host name on all networked machines to be unique
 751    (generated from MAC or reverse DNS) after boot.</li>
 752 <li>Adjusted partition sizes to make sure they are big enough.</li>
 753
 754 </ul>
 755
 756 <p><strong>Known issues</strong></p>
 757
 758 <ul>
 759
 760 <li>Grub is missing the new artwork.</li>

 814       <div class="date">17th July 2013</div>
 815       <div class="body"><p>Today I switched to
 816 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">my
 817 new laptop</a>.  I've previously written about the problems I had with
 818 my new Thinkpad X230, which was delivered with an
 819 <a href="http://people.skolelinux.org/pere/blog/Intel_SSD_520_Series_180_GB_with_Lenovo_firmware_still_lock_up_from_sustained_writes.html">180
 820 GB Intel SSD disk with Lenovo firmware</a> that did not handle
 821 sustained writes.  My hardware supplier have been very forthcoming in
 822 trying to find a solution, and after first trying with another
 823 identical 180 GB disks they decided to send me a 256 GB Samsung SSD
 824 disk instead to fix it once and for all.  The Samsung disk survived
 825 the installation of Debian with encrypted disks (filling the disk with
 826 random data during installation killed the first two), and I thus
 827 decided to trust it with my data.  I have installed it as a Debian Edu
 828 Wheezy roaming workstation hooked up with my Debian Edu Squeeze main
 829 server at home using Kerberos and LDAP, and will use it as my work
 830 station from now on.</p>
 831
 832 <p>As this is a solid state disk with no moving parts, I believe the
 833 Debian Wheezy default installation need to be tuned a bit to increase
 834 performance and increase life time of the disk.  The Linux kernel and
 835 user space applications do not yet adjust automatically to such
 836 environment.  To make it easier for my self, I created a draft Debian
 837 package <tt>ssd-setup</tt> to handle this tuning.  The
 838 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/ssd-setup.git">source
 839 for the ssd-setup package</a> is available from collab-maint, and it
 840 is set up to adjust the setup of the machine by just installing the
 841 package.  If there is any non-SSD disk in the machine, the package
 842 will refuse to install, as I did not try to write any logic to sort
 843 file systems in SSD and non-SSD file systems.</p>
 844
 845 <p>I consider the package a draft, as I am a bit unsure how to best
 846 set up Debian Wheezy with an SSD.  It is adjusted to my use case,
 847 where I set up the machine with one large encrypted partition (in
 848 addition to /boot), put LVM on top of this and set up partitions on
 849 top of this again.  See the README file in the package source for the
 850 references I used to pick the settings.  At the moment these
 851 parameters are tuned:</p>
 852
 853 <ul>
 854
 855 <li>Set up cryptsetup to pass TRIM commands to the physical disk
 856     (adding discard to /etc/crypttab)</li>
 857
 858 <li>Set up LVM to pass on TRIM commands to the underlying device (in
 859     this case a cryptsetup partition) by changing issue_discards from
 860     0 to 1 in /etc/lvm/lvm.conf.</li>
 861
 862 <li>Set relatime as a file system option for ext3 and ext4 file
 863     systems.</li>
 864
 865 <li>Tell swap to use TRIM commands by adding 'discard' to
 866     /etc/fstab.</li>
 867
 868 <li>Change I/O scheduler from cfq to deadline using a udev rule.</li>
 869
 870 <li>Run fstrim on every ext3 and ext4 file system every night (from
 871     cron.daily).</li>
 872
 873 <li>Adjust sysctl values vm.swappiness to 1 and vm.vfs_cache_pressure
 874     to 50 to reduce the kernel eagerness to swap out processes.</li>
 875
 876 </ul>
 877
 878 <p>During installation, I cancelled the part where the installer fill
 879 the disk with random data, as this would kill the SSD performance for
 880 little gain.  My goal with the encrypted file system is to ensure
 881 those stealing my laptop end up with a brick and not a working
 882 computer.  I have no hope in keeping the really resourceful people
 883 from getting the data on the disk (see
 884 <a href="http://xkcd.com/538/">XKCD #538</a> for an explanation why).
 885 Thus I concluded that adding the discard option to crypttab is the
 886 right thing to do.</p>
 887
 888 <p>I considered using the noop I/O scheduler, as several recommended
 889 it for SSD, but others recommended deadline and a benchmark I found
 890 indicated that deadline might be better for interactive use.</p>
 891
 892 <p>I also considered using the 'discard' file system option for ext3
 893 and ext4, but read that it would give a performance hit ever time a
 894 file is removed, and thought it best to that that slowdown once a day
 895 instead of during my work.</p>
 896
 897 <p>My package do not set up tmpfs on /var/run, /var/lock and /tmp, as
 898 this is already done by Debian Edu.</p>
 899
 900 <p>I have not yet started on the user space tuning.  I expect
 901 iceweasel need some tuning, and perhaps other applications too, but
 902 have not yet had time to investigate those parts.</p>
 903
 904 <p>The package should work on Ubuntu too, but I have not yet tested it
 905 there.</p>
 906
 907 <p>As for the answer to the question in the title of this blog post,
 908 as far as I know, the only solution I know about is to replace the
 909 disk.  It might be possible to flash it with Intel firmware instead of
 910 the Lenovo firmware.  But I have not tried and did not want to do so
 911 without approval from Lenovo as I wanted to keep the warranty on the
 912 disk until a solution was found and they wanted the broken disks
 913 back.</p>

 927       <div class="date">10th July 2013</div>
 928       <div class="body"><p>A few days ago, I wrote about
 929 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">the
 930 problems I experienced with my new X230 and its SSD disk</a>, which
 931 was dying during installation because it is unable to cope with
 932 sustained write.  My supplier is in contact with
 933 <a href="http://www.lenovo.com/">Lenovo</a>, and they wanted to send a
 934 replacement disk to try to fix the problem.  They decided to send an
 935 identical model, so my hopes for a permanent fix was slim.</p>
 936
 937 <p>Anyway, today I got the replacement disk and tried to install
 938 Debian Edu Wheezy with encrypted disk on it.  The new disk have the
 939 same firmware version as the original.  This time my hope raised
 940 slightly as the installation progressed, as the original disk used to
 941 die after 4-7% of the disk was written to, while this time it kept
 942 going past 10%, 20%, 40% and even past 50%.  But around 60%, the disk
 943 died again and I was back on square one.  I still do not have a new
 944 laptop with a disk I can trust.  I can not live with a disk that might
 945 lock up when I download a new
 946 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> ISO or
 947 other large files.  I look forward to hearing from my supplier with
 948 the next proposal from Lenovo.</p>
 949
 950 <p>The original disk is marked Intel SSD 520 Series 180 GB,

1009       <div class="date"> 5th July 2013</div>
1010       <div class="body"><p>Half a year ago, I reported that I had to find a
1011 <a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">replacement
1012 for my trusty old Thinkpad X41</a>.  Unfortunately I did not have much
1013 time to spend on it, and it took a while to find a model I believe
1014 will do the job, but two days ago the replacement finally arrived.  I
1015 ended up picking a
1016 <a href="http://www.linlap.com/lenovo_thinkpad_x230">Thinkpad X230</a>
1017 with SSD disk (NZDAJMN).  I first test installed Debian Edu Wheezy as
1018 a roaming workstation, and it seemed to work flawlessly.  But my
1019 second installation with encrypted disk was not as successful.  More
1020 on that below.</p>
1021
1022 <p>I had a hard time trying to track down a good laptop, as my most
1023 important requirements (robust and with a good keyboard) are never
1024 listed in the feature list.  But I did get good help from the search
1025 feature at <a href="http://www.prisjakt.no/">Prisjakt</a>, which
1026 allowed me to limit the list of interesting laptops based on my other
1027 requirements.  A bit surprising that SSD disk are not disks according
1028 to that search interface, so I had to drop specifying the number of
1029 disks from my search parameters.  I also asked around among friends to
1030 get their impression on keyboards and robustness.</p>
1031
1032 <p>So the new laptop arrived, and it is quite a lot wider than the
1033 X41.  I am not quite convinced about the keyboard, as it is
1034 significantly wider than my old keyboard, and I have to stretch my
1035 hand a lot more to reach the edges.  But the key response is fairly
1036 good and the individual key shape is fairly easy to handle, so I hope
1037 I will get used to it.  My old X40 was starting to fail, and I really
1038 needed a new laptop now. :)</p>
1039
1040 <p>Turning off the touch pad was simple.  All it took was a quick
1041 visit to the BIOS during boot it disable it.</p>
1042
1043 <p>But there is a fatal problem with the laptop.  The 180 GB SSD disk
1044 lock up during load.  And this happen when installing Debian Wheezy
1045 with encrypted disk, while the disk is being filled with random data.
1046 I also tested to install Ubuntu Raring, and it happen there too if I
1047 reenable the code to fill the disk with random data (it is disabled by
1048 default in Ubuntu).  And the bug with is already known.  It was
1049 reported to Debian as <a href="http://bugs.debian.org/691427">BTS
1050 report #691427 2012-10-25</a> (journal commit I/O error on brand-new
1051 Thinkpad T430s ext4 on lvm on SSD).  It is also reported to the Linux
1052 kernel developers as
1053 <a href="https://bugzilla.kernel.org/show_bug.cgi?id=51861">Kernel bugzilla
1054 report #51861 2012-12-20</a> (Intel SSD 520 stops working under load
1055 (SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the
1056 Lenovo forums, both for
1057 <a href="http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T430s-Intel-SSD-520-180GB-issue/m-p/1070549">T430
1058 2012-11-10</a> and for
1059 <a href="http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/x230-SATA-errors-with-180GB-Intel-520-SSD-under-heavy-write-load/m-p/1068147">X230
1060 03-20-2013</a>.  The problem do not only affect installation.  The
1061 reports state that the disk lock up during use if many writes are done
1062 on the disk, so it is much no use to work around the installation
1063 problem and end up with a computer that can lock up at any moment.
1064 There is even a
1065 <a href="https://git.efficios.com/?p=test-ssd.git">small C program
1066 available</a> that will lock up the hard drive after running a few
1067 minutes by writing to a file.</p>
1068
1069 <p>I've contacted my supplier and asked how to handle this, and after
1070 contacting PCHELP Norway (request 01D1FDP) which handle support
1071 requests for Lenovo, his first suggestion was to upgrade the disk
1072 firmware.  Unfortunately there is no newer firmware available from
1073 Lenovo, as my disk already have the most recent one (version LF1i).  I
1074 hope to hear more from him today and hope the problem can be
1075 fixed. :)</p>
