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

</p
>
130 <p
>Once you get your freedombox operational, you can visit
131 <tt
>http://your-host-name:

</tt
> to see the state of the plint
132 welcome screen (dead end - do not be surprised if you are unable to

>I
2011 raderte et stortingsflertall bestående av Høyre og
145 Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske
146 folk. Det ble vedtatt at det skulle registreres og lagres i et halvt
147 år hvor alle som bærer på en mobiltelefon befinner seg, hvem de
148 snakker med og hvor lenge de snakket sammen. Det skal også
149 registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost
150 til, og hvilke nett-tjenere en besøkte. Saken er kjent som
151 <a href=
"http://beta.holderdeord.no/issues/innfore-datalagringsdirektivet
">Datalagringsdirektivet
152 (DLD)
</a
>, og innebærer at alle innbyggerne og andre innenfor Norges
153 grenser overvåkes døgnet rundt. Det ble i praksis innført brev og
154 besøkskontroll av hele befolkningen. Rapporter fra de landene som
155 allerede har innført slik total lagring av borgernes
156 kommunikasjonsmønstre forteller at det ikke hjelper i
157 kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre
158 millioner, uten at det ser ut til å bidra positivt til politiets
159 arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt
160 på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen.
162 <a href=

163 og
<a href=
"http://www.uhuru.biz/?cat=

</a
>.
</p
>
165 <p
>Hva er problemet, tenkter du kanskje? Et åpenbart problem er at
166 medienes kildevern i praksis blir radert ut. Den innsamlede
167 informasjonen gjør det mulig å finne ut hvem som har snakket med
168 journalister på telefon, SMS og epost, og hvem som har vært i nærheten
169 av journalister så sant begge bar med seg en telefon. Et annet er at
170 advokatvernet blir sterkt redusert, der politiet kan finne ut hvem
171 som har snakket med en advokat når, eller vært i møter en med advokat.
172 Et tredje er at svært personlig informasjon kan avledes fra hvilke
173 nettsteder en har besøkt. Har en besøkt hivnorge.no,
174 swingersnorge.com eller andre sider som kan brukes til avlede
175 interesser som hører til privatsfæren, vil denne informasjonen være
176 tilgjengelig takket være datalagringsdirektivet.
</p
>
178 <p
>De fleste partiene var mot, kun to partier stemte for. Høyre og
179 Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har
180 DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre
181 fylkene). Det er dermed helt uaktuelt for meg å stemme på disse
182 partiene. Her er oversikten over partienes valglister i Oslo, med
183 informasjon om hvem som stemte hva i første DLD-votering i Stortinget,
184 basert på informasjon fra mine venner i

433 <p
><a href=
"http://www.skolelinux.org/
">Debian Edu, also known as
434 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
435 out-of-the box environment of a completely configured school
436 network. Immediately after installation a school server running all
437 services needed for a school network is set up just waiting for users
438 and machines being added via GOsa², a comfortable Web-UI. A netbooting
439 environment is prepared using PXE, so after initial installation of
440 the main server from CD or USB stick all other machines can be
441 installed via the network. The provided school server provides LDAP
442 database and Kerberos authentication service, centralized home
443 directories, DHCP server, web proxy and many other services. The
445 <a href=

">more
446 than
60 educational software packages
</a
> and more are available from
447 the Debian archive, and schools can choose between KDE, Gnome, LXDE
448 and Xfce desktop environment.
</p
>
450 <p
>This is the sixth test release based on Debian Wheezy. Basically this
451 is an updated and slightly improved version compared to the Squeeze
454 <p
>ALERT: Alpha based installations should reinstall or downgrade the
455 versions of gosa and libpam-mklocaluser to the ones used in this beta
456 release. Both alpha and beta0 based installations should reinstall or
457 deal with gosa.conf manually; there are two options: (
1) Keep
458 gosa.conf and edit this file as outlined
459 <a href=
"http://lists.debian.org/debian-edu/
2013/
08/msg00127.html
">on
460 the mailing list
</a
>. (
2) Accept the new version of gosa.conf and
461 replace both contained admin password placeholders with the password
462 hashes found in the old one (backup copy!). In both cases every user
463 need to change their their password to make sure a password is set for
464 CIFS access to their home directory.
</p
>
466 <p
><strong
>Software updates
</strong
></p
>
470 <li
>Added ssh askpass packages to default installation, to ensure ssh
471 work also without a attached tty.
</li
>
472 <li
>Add the command-not-found package to the default installation to
473 make it easier to figure out where to find missing command line
474 tools. Please note, that the command
'update-command-not-found
'
475 has to be run as root to actually make it useful (internet access
476 required).
</li
>
480 <p
><strong
>Other changes
</strong
></p
>
484 <li
>Adjusted the USB stick ISO image build to include every tool
485 needed for desktop=xfce installations.
</li
>
486 <li
>Adjust thin-client-server task to work when installing from USB
487 stick ISO image.
</li
>
488 <li
>Made new grub artwork (changed png from indexed to RGB format).
</li
>
489 <li
>Minor cleanup in the CUPS setup.
</li
>
490 <li
>Make sure that bootstrapping of the Samba domain really happens
491 during installation of the main server and adjust SID handling to
492 cope with this.
</li
>
493 <li
>Make Samba passwords changeable (again) via GOsa².
</li
>
494 <li
>Fix generation of LM and NT password hashes via GOsa² to avoid
495 empty password hashes.
</li
>
496 <li
>Adapted Samba machine domain joining to latest change in the
497 smbldap-tools Perl package, fixing bugs blocking Windows machines
498 from joining the Samba domain.
</li

506 <li
>KDE fails to understand the wpad.dat file provided, causing it to
507 not use the http proxy as it should.

557 problems using an Intel SSD
520 Series
180 GB disk
</a

558 told by IBM that the original disk should be thrown away. And as
559 there no longer was a problem if I bricked the firmware, I decided
560 today to try to install Intel firmware to replace the Lenovo firmware
561 currently on the disk.
</p

563 <p

565 (aka Intel SATA Solid-State Drive Firmware Update Tool) which
566 according to the site should contain the latest firmware for SSD
567 disks. I inserted the broken disk in one of my spare laptops and
568 booted the ISO from a USB stick. The disk was recognized, but the
569 program claimed the newest firmware already were installed and refused
570 to insert any Intel firmware. So no change, and the disk is still
571 unable to handle write load. :( I guess the only way to get them
572 working would be if Lenovo releases new firmware. No idea how likely
573 that is. Anyway, just blogging about this test for completeness. I
574 got a working Samsung disk, and see no point in spending more time on
575 the broken disks.

>It has been a while since my last update. Since last summer, I
585 have worked on a Norwegian

2004 book
587 <a href=
"http://free-culture.cc/
">Free Culture
</a
> by Lawrence Lessig,
588 to get a Norwegian text explaining the problems with the copyright
589 law. Yesterday, I finally broken the
90% mark, when counting the
590 number of strings to translate. Due to real life constraints, I have
591 not had time to work on it since March, but when the summer broke out,
592 I found time to work on it again. Still lots of work left, but the
593 first draft is nearing completion. I created a graph to show the
594 progress of the translation:

598 <p
>When the first draft is done, the translated text need to be
599 proof read, and the remaining formatting problems with images and SVG
600 drawings need to be fixed. There are probably also some index entries
601 missing that need to be added. This can be done by comparing the
602 index entries listed in the SiSU version of the book, or comparing the
603 English docbook version with the paper version. Last, the colophon
604 page with ISBN numbers etc need to be wrapped up before the release is
605 done. I should also figure out how to get correct Norwegian sorting
606 of the index pages. All docbook tools I have tried so far (xmlto,
607 docbook-xsl, dblatex) get the order of symbols and the special
608 Norwegian letters ÆØÅ wrong.
</p
>
610 <p
>There is still need for translators and people with docbook
611 knowledge, to be able to get a good looking book (I still struggle
612 with dblatex, xmlto and docbook-xsl) as well as to do the draft
613 translation and proof reading. And I would like the figures to be
614 redrawn as SVGs to make it easy to translate them. Any SVG master
615 around? There are also some legal terms that are unfamiliar to me.

>Today I switched to
769 <a href=
"http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html
">my
770 new laptop
</a
>. I
've previously written about the problems I had with
771 my new Thinkpad X230, which was delivered with an
772 <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
773 GB Intel SSD disk with Lenovo firmware
</a
> that did not handle
774 sustained writes. My hardware supplier have been very forthcoming in
775 trying to find a solution, and after first trying with another
776 identical
180 GB disks they decided to send me a
256 GB Samsung SSD
777 disk instead to fix it once and for all. The Samsung disk survived
778 the installation of Debian with encrypted disks (filling the disk with
779 random data during installation killed the first two), and I thus
780 decided to trust it with my data. I have installed it as a Debian Edu
781 Wheezy roaming workstation hooked up with my Debian Edu Squeeze main
782 server at home using Kerberos and LDAP, and will use it as my work
783 station from now on.
</p
>
785 <p
>As this is a solid state disk with no moving parts, I believe the
786 Debian Wheezy default installation need to be tuned a bit to increase
787 performance and increase life time of the disk. The Linux kernel and
788 user space applications do not yet adjust automatically to such
789 environment. To make it easier for my self, I created a draft Debian
790 package
<tt
>ssd-setup
</tt
> to handle this tuning. The
791 <a href=
"http://anonscm.debian.org/gitweb/?p=collab-maint/ssd-setup.git
">source
792 for the ssd-setup package
</a
> is available from collab-maint, and it
793 is set up to adjust the setup of the machine by just installing the
794 package. If there is any non-SSD disk in the machine, the package
795 will refuse to install, as I did not try to write any logic to sort
796 file systems in SSD and non-SSD file systems.
</p
>
798 <p
>I consider the package a draft, as I am a bit unsure how to best
799 set up Debian Wheezy with an SSD. It is adjusted to my use case,
800 where I set up the machine with one large encrypted partition (in
801 addition to /boot), put LVM on top of this and set up partitions on
802 top of this again. See the README file in the package source for the
803 references I used to pick the settings. At the moment these
804 parameters are tuned:
</p
>
808 <li
>Set up cryptsetup to pass TRIM commands to the physical disk
809 (adding discard to /etc/crypttab)
</li
>
811 <li
>Set up LVM to pass on TRIM commands to the underlying device (in
812 this case a cryptsetup partition) by changing issue_discards from
813 0 to
1 in /etc/lvm/lvm.conf.
</li
>
815 <li
>Set relatime as a file system option for ext3 and ext4 file
818 <li
>Tell swap to use TRIM commands by adding
'discard
' to
819 /etc/fstab.
</li
>
821 <li
>Change I/O scheduler from cfq to deadline using a udev rule.
</li
>
823 <li
>Run fstrim on every ext3 and ext4 file system every night (from
824 cron.daily).
</li
>
826 <li
>Adjust sysctl values vm.swappiness to
1 and vm.vfs_cache_pressure
827 to
50 to reduce the kernel eagerness to swap out processes.
</li
>
831 <p
>During installation, I cancelled the part where the installer fill
832 the disk with random data, as this would kill the SSD performance for
833 little gain. My goal with the encrypted file system is to ensure
834 those stealing my laptop end up with a brick and not a working
835 computer. I have no hope in keeping the really resourceful people
836 from getting the data on the disk (see
837 <a href=
"http://xkcd.com/
538/
">XKCD #
538</a
> for an explanation why).
838 Thus I concluded that adding the discard option to crypttab is the
839 right thing to do.
</p
>
841 <p
>I considered using the noop I/O scheduler, as several recommended
842 it for SSD, but others recommended deadline and a benchmark I found
843 indicated that deadline might be better for interactive use.
</p
>
845 <p
>I also considered using the
'discard
' file system option for ext3
846 and ext4, but read that it would give a performance hit ever time a
847 file is removed, and thought it best to that that slowdown once a day
848 instead of during my work.
</p
>
850 <p
>My package do not set up tmpfs on /var/run, /var/lock and /tmp, as
851 this is already done by Debian Edu.
</p
>
853 <p
>I have not yet started on the user space tuning. I expect
854 iceweasel need some tuning, and perhaps other applications too, but
855 have not yet had time to investigate those parts.
</p
>
857 <p
>The package should work on Ubuntu too, but I have not yet tested it
860 <p
>As for the answer to the question in the title of this blog post,
861 as far as I know, the only solution I know about is to replace the
862 disk. It might be possible to flash it with Intel firmware instead of
863 the Lenovo firmware. But I have not tried and did not want to do so
864 without approval from Lenovo as I wanted to keep the warranty on the
865 disk until a solution was found and they wanted the broken disks

877 problems I experienced with my new X230 and its SSD disk

882 identical model, so my hopes for a permanent fix was slim.

885 Debian Edu Wheezy with encrypted disk on it. The new disk have the
886 same firmware version as the original. This time my hope raised
887 slightly as the installation progressed, as the original disk used to
888 die after
4-

889 going past
10%,
20%,
40% and even past
50%. But around
60%, the disk
890 died again and I was back on square one. I still do not have a new

892 lock up when I download a new

946 <a href=
"http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html
">replacement
947 for my trusty old Thinkpad X41
</a
>. Unfortunately I did not have much
948 time to spend on it, and it took a while to find a model I believe
949 will do the job, but two days ago the replacement finally arrived. I
951 <a href=
"http://www.linlap.com/lenovo_thinkpad_x230
">Thinkpad X230
</a
>
952 with SSD disk (NZDAJMN). I first test installed Debian Edu Wheezy as
953 a roaming workstation, and it seemed to work flawlessly. But my
954 second installation with encrypted disk was not as successful. More
955 on that below.
</p
>
957 <p
>I had a hard time trying to track down a good laptop, as my most
958 important requirements (robust and with a good keyboard) are never
959 listed in the feature list. But I did get good help from the search
960 feature at
<a href=
"http://www.prisjakt.no/
">Prisjakt
</a
>, which
961 allowed me to limit the list of interesting laptops based on my other
962 requirements. A bit surprising that SSD disk are not disks according
963 to that search interface, so I had to drop specifying the number of
964 disks from my search parameters. I also asked around among friends to
965 get their impression on keyboards and robustness.
</p
>
967 <p
>So the new laptop arrived, and it is quite a lot wider than the
968 X41. I am not quite convinced about the keyboard, as it is
969 significantly wider than my old keyboard, and I have to stretch my
970 hand a lot more to reach the edges. But the key response is fairly
971 good and the individual key shape is fairly easy to handle, so I hope
972 I will get used to it. My old X40 was starting to fail, and I really
973 needed a new laptop now. :)
</p
>
975 <p
>Turning off the touch pad was simple. All it took was a quick
976 visit to the BIOS during boot it disable it.
</p
>
978 <p
>But there is a fatal problem with the laptop. The
180 GB SSD disk
979 lock up during load. And this happen when installing Debian Wheezy
980 with encrypted disk, while the disk is being filled with random data.
981 I also tested to install Ubuntu Raring, and it happen there too if I
982 reenable the code to fill the disk with random data (it is disabled by
983 default in Ubuntu). And the bug with is already known. It was
984 reported to Debian as
