32 NRK nå har bestemt seg for
33 <a href="http://www.nuug.no/news/NRK_viser_filmen_om_Datalagringsdirektivet_f_rste_gang_2014_03_31.shtml">når
34 den norske dokumentarfilmen om datalagringsdirektivet skal
35 sendes</a> (se <a href="http://www.imdb.com/title/tt2832844/">IMDB</a>
36 for detaljer om filmen) . Første visning blir på NRK2 mandag

39 Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv. Som
40 oppvarming mens vi venter anbefaler jeg Bjørn Stærks kronikk i
41 Aftenposten fra i går,
42 <a href="http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html">Autoritær
43 gjøkunge</a>, der han gir en grei skisse av hvor ille det står til med
44 retten til privatliv og beskyttelsen av demokrati i Norge og resten
45 verden, og helt riktig slår fast at det er vi i databransjen som
46 sitter med nøkkelen til å gjøre noe med dette. Jeg har involvert meg
47 i prosjektene <a href="http://www.dugnadsnett.no/">dugnadsnett.no</a>
48 og <a href="https://wiki.debian.org/FreedomBox">FreedomBox</a> for å
49 forsøke å gjøre litt selv for å bedre situasjonen, men det er mye
50 hardt arbeid fra mange flere enn meg som gjenstår før vi kan sies å ha
51 gjenopprettet balansen.</p>
52
53 <p>Jeg regner med at nettutgaven dukker opp på
54 <a href="http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet">NRKs
55 side om filmen om datalagringsdirektivet</a> om frem dager. Hold et
56 øye med siden, og tips venner og slekt om at de også bør se den.</p>

77 <p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
78 project</a> is working on providing the software and hardware for
79 making it easy for non-technical people to host their data and
80 communication at home, and being able to communicate with their
81 friends and family encrypted and away from prying eyes. It has been
82 going on for a while, and is slowly progressing towards a new test
83 release (0.2).</p>
84
85 <p>And what day could be better than the Pi day to announce that the
86 new version will provide "hard drive" / SD card / USB stick images for
87 Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
88 system), and can also be installed using a Debian installer preseed
89 file. The Debian based Freedombox is now based on Debian Jessie,
90 where most of the needed packages used are already present. Only one,
91 the freedombox-setup package, is missing. To try to build your own
92 boot image to test the current status, fetch the freedom-maker scripts
93 and build using
94 <a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
95 with a user with sudo access to become root:
96
97 <pre>
98 git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
99 freedom-maker
100 sudo apt-get install git vmdebootstrap mercurial python-docutils \
101 mktorrent extlinux virtualbox qemu-user-static binfmt-support \
102 u-boot-tools
103 make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
104 </pre>
105
106 <p>Root access is needed to run debootstrap and mount loopback
107 devices. See the README for more details on the build. If you do not
108 want all three images, trim the make line. But note that thanks to <a
109 href="https://bugs.debian.org/741407">a race condition in
110 vmdebootstrap</a>, the build might fail without the patch to the
111 kpartx call.</p>
112
113 <p>If you instead want to install using a Debian CD and the preseed
114 method, boot a Debian Wheezy ISO and use this boot argument to load
115 the preseed values:</p>
116
117 <pre>
118 url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
119 </pre>
120
121 <p>But note that due to <a href="https://bugs.debian.org/740673">a
122 recently introduced bug in apt in Jessie</a>, the installer will
123 currently hang while setting up APT sources. Killing the
124 '<tt>apt-cdrom ident</tt>' process when it hang a few times during the
125 installation will get the installation going. This affect all
126 installations in Jessie, and I expect it will be fixed soon.</p>
127
128 Give it a go and let us know how it goes on the mailing list, and help
129 us get the new release published. :) Please join us on
130 <a href="irc://irc.debian.org:6667/%23freedombox">IRC (#freedombox on
131 irc.debian.org)</a> and
132 <a href="http://lists.alioth.debian.org/mailman/listinfo/freedombox-discuss">the
133 mailing list</a> if you want to help make this vision come true.</p>

154 <p>The
155 <a href="http://packages.qa.debian.org/v/vmdebootstrap.html">vmdebootstrap</a>
156 program is a a very nice system to create virtual machine images. It
157 create a image file, add a partition table, mount it and run
158 debootstrap in the mounted directory to create a Debian system on a
159 stick. Yesterday, I decided to try to teach it how to make images for
160 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi</a>, as part
161 of a plan to simplify the build system for
162 <a href="https://wiki.debian.org/FreedomBox">the FreedomBox
163 project</a>. The FreedomBox project already uses vmdebootstrap for
164 the virtualbox images, but its current build system made multistrap
165 based system for Dreamplug images, and it is lacking support for
166 Raspberry Pi.</p>
167
168 <p>Armed with the knowledge on how to build "foreign" (aka non-native
169 architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
170 code and adjusted it to be able to build armel images on my amd64
171 Debian laptop. I ended up giving vmdebootstrap five new options,
172 allowing me to replicate the image creation process I use to make
173 <a href="http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html">Debian
174 Jessie based mesh node images for the Raspberry Pi</a>. First, the
175 <tt>--foreign /path/to/binfm_handler</tt> option tell vmdebootstrap to
176 call debootstrap with --foreign and to copy the handler into the
177 generated chroot before running the second stage. This allow
178 vmdebootstrap to create armel images on an amd64 host. Next I added
179 two new options <tt>--bootsize size</tt> and <tt>--boottype
180 fstype</tt> to teach it to create a separate /boot/ partition with the
181 given file system type, allowing me to create an image with a vfat
182 partition for the /boot/ stuff. I also added a <tt>--variant
183 variant</tt> option to allow me to create smaller images without the
184 Debian base system packages installed. Finally, I added an option
185 <tt>--no-extlinux</tt> to tell vmdebootstrap to not install extlinux
186 as a boot loader. It is not needed on the Raspberry Pi and probably
187 most other non-x86 architectures. The changes were accepted by the
188 upstream author of vmdebootstrap yesterday and today, and is now
189 available from
190 <a href="http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/">the
191 upstream project page</a>.</p>
192
193 <p>To use it to build a Raspberry Pi image using Debian Jessie, first
194 create a small script (the customize script) to add the non-free
195 binary blob needed to boot the Raspberry Pi and the APT source
196 list:</p>
197
198 <p><pre>
199 #!/bin/sh
200 set -e # Exit on first error
201 rootdir="$1"
202 cd "$rootdir"
203 cat &lt;&lt;EOF > etc/apt/sources.list
204 deb http://http.debian.net/debian/ jessie main contrib non-free
205 EOF
206 # Install non-free binary blob needed to boot Raspberry Pi. This
207 # install a kernel somewhere too.
208 wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
209 -O $rootdir/usr/bin/rpi-update
210 chmod a+x $rootdir/usr/bin/rpi-update
211 mkdir -p $rootdir/lib/modules
212 touch $rootdir/boot/start.elf
213 chroot $rootdir rpi-update
214 </pre></p>
215
216 <p>Next, fetch the latest vmdebootstrap script and call it like this
217 to build the image:</p>
218
219 <pre>
220 sudo ./vmdebootstrap \
221 --variant minbase \
222 --arch armel \
223 --distribution jessie \
224 --mirror http://http.debian.net/debian \
225 --image test.img \
226 --size 600M \
227 --bootsize 64M \
228 --boottype vfat \
229 --log-level debug \
230 --verbose \
231 --no-kernel \
232 --no-extlinux \
233 --root-password raspberry \
234 --hostname raspberrypi \
235 --foreign /usr/bin/qemu-arm-static \
236 --customize `pwd`/customize \
237 --package netbase \
238 --package git-core \
239 --package binutils \
240 --package ca-certificates \
241 --package wget \
242 --package kmod
243 </pre></p>
244
245 <p>The list of packages being installed are the ones needed by
246 rpi-update to make the image bootable on the Raspberry Pi, with the
247 exception of netbase, which is needed by debootstrap to find
248 /etc/hosts with the minbase variant. I really wish there was a way to
249 set up an Raspberry Pi using only packages in the Debian archive, but
250 that is not possible as far as I know, because it boots from the GPU
251 using a non-free binary blob.</p>
252
253 <p>The build host need debootstrap, kpartx and qemu-user-static and
254 probably a few others installed. I have not checked the complete
255 build dependency list.</p>
256
257 <p>The resulting image will not use the hardware floating point unit
258 on the Raspberry PI, because the armel architecture in Debian is not
259 optimized for that use. So the images created will be a bit slower
260 than <a href="http://www.raspbian.org/">Raspbian</a> based images.</p>

276 </div>
277 <div class="date">
278 21st October 2013
279 </div>
280 <div class="body">
281 <p>The last few days I have been experimenting with
282 <a href="http://www.open-mesh.org/projects/batman-adv/wiki">the
283 batman-adv mesh technology</a>. I want to gain some experience to see
284 if it will fit <a href="https://wiki.debian.org/FreedomBox">the
285 Freedombox project</a>, and together with my neighbors try to build a
286 mesh network around the park where I live. Batman-adv is a layer 2
287 mesh system ("ethernet" in other words), where the mesh network appear
288 as if all the mesh clients are connected to the same switch.</p>
289
290 <p>My hardware of choice was the Linksys WRT54GL routers I had lying
291 around, but I've been unable to get them working with batman-adv. So
292 instead, I started playing with a
293 <a href="http://www.raspberrypi.org/">Raspberry Pi</a>, and tried to
294 get it working as a mesh node. My idea is to use it to create a mesh
295 node which function as a switch port, where everything connected to
296 the Raspberry Pi ethernet plug is connected (bridged) to the mesh
297 network. This allow me to hook a wifi base station like the Linksys
298 WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
299 non-mesh clients to hook up to the mesh. This in turn is useful for
300 Android phones using <a href="http://servalproject.org/">the Serval
301 Project</a> voip client, allowing every one around the playground to
302 phone and message each other for free. The reason is that Android
303 phones do not see ad-hoc wifi networks (they are filtered away from
304 the GUI view), and can not join the mesh without being rooted. But if
305 they are connected using a normal wifi base station, they can talk to
306 every client on the local network.</p>
307
308 <p>To get this working, I've created a debian package
309 <a href="https://github.com/petterreinholdtsen/meshfx-node">meshfx-node</a>
310 and a script
311 <a href="https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node">build-rpi-mesh-node</a>
312 to create the Raspberry Pi boot image. I'm using Debian Jessie (and
313 not Raspbian), to get more control over the packages available.
314 Unfortunately a huge binary blob need to be inserted into the boot
315 image to get it booting, but I'll ignore that for now. Also, as
316 Debian lack support for the CPU features available in the Raspberry
317 Pi, the system do not use the hardware floating point unit. I hope
318 the routing performance isn't affected by the lack of hardware FPU
319 support.</p>
320
321 <p>To create an image, run the following with a sudo enabled user
322 after inserting the target SD card into the build machine:</p>
323
324 <p><pre>
325 % wget -O build-rpi-mesh-node \
326 https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
327 % sudo bash -x ./build-rpi-mesh-node > build.log 2>&1
328 % dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
329 %
330 </pre></p>
331
332 <p>Booting with the resulting SD card on a Raspberry PI with a USB
333 wifi card inserted should give you a mesh node. At least it does for
334 me with a the wifi card I am using. The default mesh settings are the
335 ones used by the Oslo mesh project at Hackeriet, as I mentioned in
336 <a href="http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html">an
337 earlier blog post about this mesh testing</a>.</p>
338
339 <p>The mesh node was not horribly expensive either. I bought
340 everything over the counter in shops nearby. If I had ordered online
341 from the lowest bidder, the price should be significantly lower:</p>
342
343 <p><table>
344
345 <tr><th>Supplier</th><th>Model</th><th>NOK</th></tr>
346 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi model B</td><td>349.90</td></tr>
347 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi type B case</td><td>99.90</td></tr>
348 <tr><td>Lefdal</td><td>Jensen Air:Link 25150</td><td>295.-</td></tr>
349 <tr><td>Clas Ohlson</td><td>Kingston 16 GB SD card</td><td>199.-</td></tr>
350 <tr><td>Total cost</td><td></td><td>943.80</td></tr>
351
352 </table></p>
353
354 <p>Now my mesh network at home consist of one laptop in the basement
355 connected to my production network, one Raspberry Pi node on the 1th
356 floor that can be seen by my neighbor across the park, and one
357 play-node I use to develop the image building script. And some times
358 I hook up my work horse laptop to the mesh to test it. I look forward
359 to figuring out what kind of latency the batman-adv setup will give,
360 and how much packet loss we will experience around the park. :)</p>

381 <p>Wireless mesh networks are self organising and self healing
382 networks that can be used to connect computers across small and large
383 areas, depending on the radio technology used. Normal wifi equipment
384 can be used to create home made radio networks, and there are several
385 successful examples like
386 <a href="http://www.freifunk.net/">Freifunk</a> and
387 <a href="http://www.awmn.net/">Athens Wireless Metropolitan Network</a>
388 (see
389 <a href="http://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region#Greece">wikipedia
390 for a large list</a>) around the globe. To give you an idea how it
391 work, check out the nice overview of the Kiel Freifunk community which
392 can be seen from their
393 <a href="http://freifunk.in-kiel.de/ffmap/nodes.html">dynamically
394 updated node graph and map</a>, where one can see how the mesh nodes
395 automatically handle routing and recover from nodes disappearing.
396 There is also a small community mesh network group in Oslo, Norway,
397 and that is the main topic of this blog post.</p>
398
399 <p>I've wanted to check out mesh networks for a while now, and hoped
400 to do it as part of my involvement with the <a
401 href="http://www.nuug.no/">NUUG member organisation</a> community, and
402 my recent involvement in
403 <a href="https://wiki.debian.org/FreedomBox">the Freedombox project</a>
404 finally lead me to give mesh networks some priority, as I suspect a
405 Freedombox should use mesh networks to connect neighbours and family
406 when possible, given that most communication between people are
407 between those nearby (as shown for example by research on Facebook
408 communication patterns). It also allow people to communicate without
409 any central hub to tap into for those that want to listen in on the
410 private communication of citizens, which have become more and more
411 important over the years.</p>
412
413 <p>So far I have only been able to find one group of people in Oslo
414 working on community mesh networks, over at the hack space
415 <a href="http://hackeriet.no/">Hackeriet</a> at Husmania. They seem to
416 have started with some Freifunk based effort using OLSR, called
417 <a href="http://oslo.freifunk.net/index.php?title=Main_Page">the Oslo
418 Freifunk project</a>, but that effort is now dead and the people
419 behind it have moved on to a batman-adv based system called
420 <a href="http://meshfx.org/trac">meshfx</a>. Unfortunately the wiki
421 site for the Oslo Freifunk project is no longer possible to update to
422 reflect this fact, so the old project page can't be updated to point to
423 the new project. A while back, the people at Hackeriet invited people
424 from the Freifunk community to Oslo to talk about mesh networks. I
425 came across this video where Hans Jørgen Lysglimt interview the
426 speakers about this talk (from
427 <a href="https://www.youtube.com/watch?v=N2Kd7CLkhSY">youtube</a>):</p>

430
431 <p>I mentioned OLSR and batman-adv, which are mesh routing protocols.
432 There are heaps of different protocols, and I am still struggling to
433 figure out which one would be "best" for some definitions of best, but
434 given that the community mesh group in Oslo is so small, I believe it
435 is best to hook up with the existing one instead of trying to create a
436 completely different setup, and thus I have decided to focus on
437 batman-adv for now. It sure help me to know that the very cool
438 <a href="http://www.servalproject.org/">Serval project in Australia</a>
439 is using batman-adv as their meshing technology when it create a self
440 organizing and self healing telephony system for disaster areas and
441 less industrialized communities. Check out this cool video presenting
442 that project (from
443 <a href="https://www.youtube.com/watch?v=30qNfzJCQOA">youtube</a>):</p>

446
447 <p>According to the wikipedia page on
448 <a href="http://en.wikipedia.org/wiki/Wireless_mesh_network">Wireless
449 mesh network</a> there are around 70 competing schemes for routing
450 packets across mesh networks, and OLSR, B.A.T.M.A.N. and
451 B.A.T.M.A.N. advanced are protocols used by several free software
452 based community mesh networks.</p>
453
454 <p>The batman-adv protocol is a bit special, as it provide layer 2
455 (as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same
456 network. One way to think about it is that it provide a mesh based
457 vlan you can bridge to or handle like any other vlan connected to your
458 computer. The required drivers are already in the Linux kernel at
459 least since Debian Wheezy, and it is fairly easy to set up. A
460 <a href="http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide">good
461 introduction</a> is available from the Open Mesh project. These are
462 the key settings needed to join the Oslo meshfx network:</p>
463
464 <p><table>
465 <tr><th>Setting</th><th>Value</th></tr>
466 <tr><td>Protocol / kernel module</td><td>batman-adv</td></tr>
467 <tr><td>ESSID</td><td>meshfx@hackeriet</td></tr>
468 <td>Channel / Frequency</td><td>11 / 2462</td></tr>
469 <td>Cell ID</td><td>02:BA:00:00:00:01</td>
470 </table></p>
471
472 <p>The reason for setting ad-hoc wifi Cell ID is to work around bugs
473 in firmware used in wifi card and wifi drivers. (See a nice post from
474 VillageTelco about
475 "<a href="http://tiebing.blogspot.no/2009/12/ad-hoc-cell-splitting-re-post-original.html">Information
476 about cell-id splitting, stuck beacons, and failed IBSS merges!</a>
477 for details.) When these settings are activated and you have some
478 other mesh node nearby, your computer will be connected to the mesh
479 network and can communicate with any mesh node that is connected to
480 any of the nodes in your network of nodes. :)</p>
481
482 <p>My initial plan was to reuse my old Linksys WRT54GL as a mesh node,
483 but that seem to be very hard, as I have not been able to locate a
484 firmware supporting batman-adv. If anyone know how to use that old
485 wifi access point with batman-adv these days, please let me know.</p>
486
487 <p>If you find this project interesting and want to join, please join
488 us on IRC, either channel
489 <a href="irc://irc.freenode.net/#oslohackerspace">#oslohackerspace</a>
490 or <a href="irc://irc.freenode.net/#nuug">#nuug</a> on
491 irc.freenode.net.</p>
492
493 <p>While investigating mesh networks in Oslo, I came across an old
494 research paper from the university of Stavanger and Telenor Research
495 and Innovation called
496 <a href="http://folk.uio.no/paalee/publications/netrel-egeland-iswcs-2008.pdf">The
497 reliability of wireless backhaul mesh networks</a> and elsewhere
498 learned that Telenor have been experimenting with mesh networks at
499 Grünerløkka in Oslo. So mesh networks are also interesting for
500 commercial companies, even though Telenor discovered that it was hard
501 to figure out a good business plan for mesh networking and as far as I
502 know have closed down the experiment. Perhaps Telenor or others would
503 be interested in a cooperation?</p>
504
505 <p><strong>Update 2013-10-12</strong>: I was just
506 <a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2013-October/005900.html">told
507 by the Serval project developers</a> that they no longer use
508 batman-adv (but are compatible with it), but their own crypto based
509 mesh system.</p>

581 a few weeks I hope everything needed to test it is included in Debian.
582 The withsqlite package is already in Debian, and the plinth package is
583 pending in NEW. The third and vital part of that puzzle is the
584 metapackage/setup framework, which is still pending an upload. Join

608 <div class="body">
609 <p>I was introduced to the
610 <a href="http://www.freedomboxfoundation.org/">Freedombox project</a>
611 in 2010, when Eben Moglen presented his vision about serving the need
612 of non-technical people to keep their personal information private and
613 within the legal protection of their own homes. The idea is to give
614 people back the power over their network and machines, and return
615 Internet back to its intended peer-to-peer architecture. Instead of
616 depending on a central service, the Freedombox will give everyone
617 control over their own basic infrastructure.</p>
618
619 <p>I've intended to join the effort since then, but other tasks have
620 taken priority. But this summers nasty news about the misuse of trust
621 and privilege exercised by the "western" intelligence gathering
622 communities increased my eagerness to contribute to a point where I
623 actually started working on the project a while back.</p>
624
625 <p>The <a href="https://alioth.debian.org/projects/freedombox/">initial
626 Debian initiative</a> based on the vision from Eben Moglen, is to
627 create a simple and cheap Debian based appliance that anyone can hook
628 up in their home and get access to secure and private services and
629 communication. The initial deployment platform have been the
630 <a href="http://www.globalscaletechnologies.com/t-dreamplugdetails.aspx">Dreamplug</a>,
631 which is a piece of hardware I do not own. So to be able to test what
632 the current Freedombox setup look like, I had to come up with a way to install
633 it on some hardware I do have access to. I have rewritten the
634 <a href="https://github.com/NickDaly/freedom-maker">freedom-maker</a>
635 image build framework to use .deb packages instead of only copying
636 setup into the boot images, and thanks to this rewrite I am able to
637 set up any machine supported by Debian Wheezy as a Freedombox, using
638 the previously mentioned deb (and a few support debs for packages
639 missing in Debian).</p>
640
641 <p>The current Freedombox setup consist of a set of bootstrapping
642 scripts
643 (<a href="https://github.com/petterreinholdtsen/freedombox-setup">freedombox-setup</a>),
644 and a administrative web interface
645 (<a href="https://github.com/NickDaly/Plinth">plinth</a> + exmachina +
646 withsqlite), as well as a privacy enhancing proxy based on
647 <a href="http://packages.qa.debian.org/privoxy">privoxy</a>
648 (freedombox-privoxy). There is also a web/javascript based XMPP
649 client (<a href="http://packages.qa.debian.org/jwchat">jwchat</a>)
650 trying (unsuccessfully so far) to talk to the XMPP server
651 (<a href="http://packages.qa.debian.org/ejabberd">ejabberd</a>). The
652 web interface is pluggable, and the goal is to use it to enable OpenID
653 services, mesh network connectivity, use of TOR, etc, etc. Not much of
654 this is really working yet, see
655 <a href="https://github.com/NickDaly/freedombox-todos/blob/master/TODO">the
656 project TODO</a> for links to GIT repositories. Most of the code is
657 on github at the moment. The HTTP proxy is operational out of the
658 box, and the admin web interface can be used to add/remove plinth
659 users. I've not been able to do anything else with it so far, but
660 know there are several branches spread around github and other places
661 with lots of half baked features.</p>
662
663 <p>Anyway, if you want to have a look at the current state, the
664 following recipes should work to give you a test machine to poke
665 at.</p>
666
667 <p><strong>Debian Wheezy amd64</strong></p>
668
669 <ol>
670
671 <li>Fetch normal Debian Wheezy installation ISO.</li>
672 <li>Boot from it, either as CD or USB stick.</li>
673 <li><p>Press [tab] on the boot prompt and add this as a boot argument
674 to the Debian installer:<p>
675 <pre>url=<a href="http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat">http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat</a></pre></li>
676
677 <li>Answer the few language/region/password questions and pick disk to
678 install on.</li>
679
680 <li>When the installation is finished and the machine have rebooted a
681 few times, your Freedombox is ready for testing.</li>
682
683 </ol>
684
685 <p><strong>Raspberry Pi Raspbian</strong></p>
686
687 <ol>
688
689 <li>Fetch a Raspbian SD card image, create SD card.</li>
690 <li>Boot from SD card, extend file system to fill the card completely.</li>
691 <li><p>Log in and add this to /etc/sources.list:</p>
692 <pre>
693 deb <a href="http://www.reinholdtsen.name/freedombox/">http://www.reinholdtsen.name/freedombox</a> wheezy main
694 </pre></li>
695 <li><p>Run this as root:</p>
696 <pre>
697 wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
698 apt-key add -
699 apt-get update
700 apt-get install freedombox-setup
701 /usr/lib/freedombox/setup
702 </pre></li>
703 <li>Reboot into your freshly created Freedombox.</li>
704
705 </ol>
706
707 <p>You can test it on other architectures too, but because the
708 freedombox-privoxy package is binary, it will only work as intended on
709 the architectures where I have had time to build the binary and put it
710 in my APT repository. But do not let this stop you. It is only a
711 short "<tt>apt-get source -b freedombox-privoxy</tt>" away. :)</p>
712
713 <p>Note that by default Freedombox is a DHCP server on the
714 192.168.1.0/24 subnet, so if this is your subnet be careful and turn
715 off the DHCP server by running "<tt>update-rc.d isc-dhcp-server
716 disable</tt>" as root.</p>
717
718 <p>Please let me know if this works for you, or if you have any
719 problems. We gather on the IRC channel
720 <a href="irc://irc.debian.org:6667/%23freedombox">#freedombox</a> on
721 irc.debian.org and the
722 <a href="http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss">project
723 mailing list</a>.</p>
724
725 <p>Once you get your freedombox operational, you can visit
726 <tt>http://your-host-name:8001/</tt> to see the state of the plint
727 welcome screen (dead end - do not be surprised if you are unable to
728 get past it), and next visit <tt>http://your-host-name:8001/help/</tt>
729 to look at the rest of plinth. The default user is 'admin' and the
730 default password is 'secret'.</p>
