  31         <p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
  32 project</a> is working on providing the software and hardware to make
  33 it easy for non-technical people to host their data and communication
  34 at home, and being able to communicate with their friends and family
  35 encrypted and away from prying eyes.  It is still going strong, and
  36 today a major mile stone was reached.</p>
  37
  38 <p>Today, the last of the packages currently used by the project to
  39 created the system images were accepted into Debian Unstable.  It was
  40 the freedombox-setup package, which is used to configure the images
  41 during build and on the first boot.  Now all one need to get going is
  42 the build code from the freedom-maker git repository and packages from
  43 Debian.  And once the freedombox-setup package enter testing, we can
  44 build everything directly from Debian. :)</p>
  45
  46 <p>Some key packages used by Freedombox are
  47 <a href="http://packages.qa.debian.org/freedombox-setup">freedombox-setup</a>,
  48 <a href="http://packages.qa.debian.org/plinth">plinth</a>,
  49 <a href="http://packages.qa.debian.org/pagekite">pagekite</a>,
  50 <a href="http://packages.qa.debian.org/tor">tor</a>,
  51 <a href="http://packages.qa.debian.org/privoxy">privoxy</a>,
  52 <a href="http://packages.qa.debian.org/owncloud">owncloud</a> and
  53 <a href="http://packages.qa.debian.org/dnsmasq">dnsmasq</a>.  There
  54 are plans to integrate more packages into the setup.  User
  55 documentation is maintained on the Debian wiki.  Please
  56 <a href="https://wiki.debian.org/FreedomBox/Manual/Jessie">check out
  57 the manual</a> and help us improve it.</p>
  58
  59 <p>To test for yourself and create boot images with the FreedomBox
  60 setup, run this on a Debian machine using a user with sudo rights to
  61 become root:</p>
  62
  63 <p><pre>
  64 sudo apt-get install git vmdebootstrap mercurial python-docutils \
  65   mktorrent extlinux virtualbox qemu-user-static binfmt-support \
  66   u-boot-tools
  67 git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
  68   freedom-maker
  69 make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
  70 </pre></p>
  71
  72 <p>Root access is needed to run debootstrap and mount loopback
  73 devices.  See the README in the freedom-maker git repo for more
  74 details on the build.  If you do not want all three images, trim the
  75 make line.  Note that the virtualbox-image target is not really
  76 virtualbox specific.  It create a x86 image usable in kvm, qemu,
  77 vmware and any other x86 virtual machine environment.  You might need
  78 the version of vmdebootstrap in Jessie to get the build working, as it
  79 include fixes for a race condition with kpartx.</p>
  80
  81 <p>If you instead want to install using a Debian CD and the preseed
  82 method, boot a Debian Wheezy ISO and use this boot argument to load
  83 the preseed values:</p>

  87 </pre></p>
  88
  89 <p>I have not tested it myself the last few weeks, so I do not know if
  90 it still work.</p>
  91
  92 <p>If you wonder how to help, one task you could look at is using
  93 systemd as the boot system.  It will become the default for Linux in
  94 Jessie, so we need to make sure it is usable on the Freedombox.  I did
  95 a simple test a few weeks ago, and noticed dnsmasq failed to start
  96 during boot when using systemd.  I suspect there are other problems
  97 too. :) To detect problems, there is a test suite included, which can
  98 be run from the plinth web interface.</p>
  99
 100 <p>Give it a go and let us know how it goes on the mailing list, and help
 101 us get the new release published. :) Please join us on
 102 <a href="irc://irc.debian.org:6667/%23freedombox">IRC (#freedombox on
 103 irc.debian.org)</a> and
 104 <a href="http://lists.alioth.debian.org/mailman/listinfo/freedombox-discuss">the

 127 NRK nå har bestemt seg for
 128 <a href="http://www.nuug.no/news/NRK_viser_filmen_om_Datalagringsdirektivet_f_rste_gang_2014_03_31.shtml">når
 129 den norske dokumentarfilmen om datalagringsdirektivet skal

 134 Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv.  Som
 135 oppvarming mens vi venter anbefaler jeg Bjørn Stærks kronikk i
 136 Aftenposten fra i går,
 137 <a href="http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html">Autoritær
 138 gjøkunge</a>, der han gir en grei skisse av hvor ille det står til med
 139 retten til privatliv og beskyttelsen av demokrati i Norge og resten
 140 verden, og helt riktig slår fast at det er vi i databransjen som
 141 sitter med nøkkelen til å gjøre noe med dette.  Jeg har involvert meg
 142 i prosjektene <a href="http://www.dugnadsnett.no/">dugnadsnett.no</a>
 143 og <a href="https://wiki.debian.org/FreedomBox">FreedomBox</a> for å
 144 forsøke å gjøre litt selv for å bedre situasjonen, men det er mye
 145 hardt arbeid fra mange flere enn meg som gjenstår før vi kan sies å ha
 146 gjenopprettet balansen.</p>
 147
 148 <p>Jeg regner med at nettutgaven dukker opp på
 149 <a href="http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet">NRKs
 150 side om filmen om datalagringsdirektivet</a> om fem dager.  Hold et
 151 øye med siden, og tips venner og slekt om at de også bør se den.</p>

 177 going on for a while, and is slowly progressing towards a new test
 178 release (0.2).</p>
 179
 180 <p>And what day could be better than the Pi day to announce that the
 181 new version will provide "hard drive" / SD card / USB stick images for
 182 Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
 183 system), and can also be installed using a Debian installer preseed
 184 file.  The Debian based Freedombox is now based on Debian Jessie,
 185 where most of the needed packages used are already present.  Only one,
 186 the freedombox-setup package, is missing.  To try to build your own
 187 boot image to test the current status, fetch the freedom-maker scripts
 188 and build using
 189 <a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
 190 with a user with sudo access to become root:
 191

 201 <p>Root access is needed to run debootstrap and mount loopback

 204 href="https://bugs.debian.org/741407">a race condition in
 205 vmdebootstrap</a>, the build might fail without the patch to the
 206 kpartx call.</p>
 207

 215
 216 <p>But note that due to <a href="https://bugs.debian.org/740673">a
 217 recently introduced bug in apt in Jessie</a>, the installer will
 218 currently hang while setting up APT sources.  Killing the
 219 '<tt>apt-cdrom ident</tt>' process when it hang a few times during the
 220 installation will get the installation going.  This affect all
 221 installations in Jessie, and I expect it will be fixed soon.</p>

 249         <p>The
 250 <a href="http://packages.qa.debian.org/v/vmdebootstrap.html">vmdebootstrap</a>
 251 program is a a very nice system to create virtual machine images.  It
 252 create a image file, add a partition table, mount it and run
 253 debootstrap in the mounted directory to create a Debian system on a
 254 stick.  Yesterday, I decided to try to teach it how to make images for
 255 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi</a>, as part
 256 of a plan to simplify the build system for
 257 <a href="https://wiki.debian.org/FreedomBox">the FreedomBox
 258 project</a>.  The FreedomBox project already uses vmdebootstrap for
 259 the virtualbox images, but its current build system made multistrap
 260 based system for Dreamplug images, and it is lacking support for
 261 Raspberry Pi.</p>
 262
 263 <p>Armed with the knowledge on how to build "foreign" (aka non-native
 264 architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
 265 code and adjusted it to be able to build armel images on my amd64
 266 Debian laptop.  I ended up giving vmdebootstrap five new options,
 267 allowing me to replicate the image creation process I use to make
 268 <a href="http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html">Debian
 269 Jessie based mesh node images for the Raspberry Pi</a>.  First, the
 270 <tt>--foreign /path/to/binfm_handler</tt> option tell vmdebootstrap to
 271 call debootstrap with --foreign and to copy the handler into the
 272 generated chroot before running the second stage.  This allow
 273 vmdebootstrap to create armel images on an amd64 host.  Next I added
 274 two new options <tt>--bootsize size</tt> and <tt>--boottype
 275 fstype</tt> to teach it to create a separate /boot/ partition with the
 276 given file system type, allowing me to create an image with a vfat
 277 partition for the /boot/ stuff.  I also added a <tt>--variant
 278 variant</tt> option to allow me to create smaller images without the
 279 Debian base system packages installed.  Finally, I added an option
 280 <tt>--no-extlinux</tt> to tell vmdebootstrap to not install extlinux
 281 as a boot loader.  It is not needed on the Raspberry Pi and probably
 282 most other non-x86 architectures.  The changes were accepted by the
 283 upstream author of vmdebootstrap yesterday and today, and is now
 284 available from
 285 <a href="http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/">the
 286 upstream project page</a>.</p>
 287
 288 <p>To use it to build a Raspberry Pi image using Debian Jessie, first
 289 create a small script (the customize script) to add the non-free
 290 binary blob needed to boot the Raspberry Pi and the APT source
 291 list:</p>
 292
 293 <p><pre>
 294 #!/bin/sh
 295 set -e # Exit on first error
 296 rootdir="$1"
 297 cd "$rootdir"
 298 cat &lt;&lt;EOF > etc/apt/sources.list
 299 deb http://http.debian.net/debian/ jessie main contrib non-free
 300 EOF
 301 # Install non-free binary blob needed to boot Raspberry Pi.  This
 302 # install a kernel somewhere too.
 303 wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
 304     -O $rootdir/usr/bin/rpi-update
 305 chmod a+x $rootdir/usr/bin/rpi-update
 306 mkdir -p $rootdir/lib/modules
 307 touch $rootdir/boot/start.elf
 308 chroot $rootdir rpi-update
 309 </pre></p>
 310
 311 <p>Next, fetch the latest vmdebootstrap script and call it like this
 312 to build the image:</p>
 313
 314 <pre>
 315 sudo ./vmdebootstrap \
 316     --variant minbase \
 317     --arch armel \
 318     --distribution jessie \
 319     --mirror http://http.debian.net/debian \
 320     --image test.img \
 321     --size 600M \
 322     --bootsize 64M \
 323     --boottype vfat \
 324     --log-level debug \
 325     --verbose \
 326     --no-kernel \
 327     --no-extlinux \
 328     --root-password raspberry \
 329     --hostname raspberrypi \
 330     --foreign /usr/bin/qemu-arm-static \
 331     --customize `pwd`/customize \
 332     --package netbase \
 333     --package git-core \
 334     --package binutils \
 335     --package ca-certificates \
 336     --package wget \
 337     --package kmod
 338 </pre></p>
 339
 340 <p>The list of packages being installed are the ones needed by
 341 rpi-update to make the image bootable on the Raspberry Pi, with the
 342 exception of netbase, which is needed by debootstrap to find
 343 /etc/hosts with the minbase variant.  I really wish there was a way to
 344 set up an Raspberry Pi using only packages in the Debian archive, but
 345 that is not possible as far as I know, because it boots from the GPU
 346 using a non-free binary blob.</p>
 347
 348 <p>The build host need debootstrap, kpartx and qemu-user-static and
 349 probably a few others installed.  I have not checked the complete
 350 build dependency list.</p>
 351
 352 <p>The resulting image will not use the hardware floating point unit
 353 on the Raspberry PI, because the armel architecture in Debian is not
 354 optimized for that use.  So the images created will be a bit slower
 355 than <a href="http://www.raspbian.org/">Raspbian</a> based images.</p>

 376         <p>The last few days I have been experimenting with
 377 <a href="http://www.open-mesh.org/projects/batman-adv/wiki">the
 378 batman-adv mesh technology</a>.  I want to gain some experience to see
 379 if it will fit <a href="https://wiki.debian.org/FreedomBox">the
 380 Freedombox project</a>, and together with my neighbors try to build a
 381 mesh network around the park where I live.  Batman-adv is a layer 2
 382 mesh system ("ethernet" in other words), where the mesh network appear
 383 as if all the mesh clients are connected to the same switch.</p>
 384
 385 <p>My hardware of choice was the Linksys WRT54GL routers I had lying
 386 around, but I've been unable to get them working with batman-adv.  So
 387 instead, I started playing with a
 388 <a href="http://www.raspberrypi.org/">Raspberry Pi</a>, and tried to
 389 get it working as a mesh node.  My idea is to use it to create a mesh
 390 node which function as a switch port, where everything connected to
 391 the Raspberry Pi ethernet plug is connected (bridged) to the mesh
 392 network.  This allow me to hook a wifi base station like the Linksys
 393 WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
 394 non-mesh clients to hook up to the mesh.  This in turn is useful for
 395 Android phones using <a href="http://servalproject.org/">the Serval
 396 Project</a> voip client, allowing every one around the playground to
 397 phone and message each other for free.  The reason is that Android
 398 phones do not see ad-hoc wifi networks (they are filtered away from
 399 the GUI view), and can not join the mesh without being rooted.  But if
 400 they are connected using a normal wifi base station, they can talk to
 401 every client on the local network.</p>
 402
 403 <p>To get this working, I've created a debian package
 404 <a href="https://github.com/petterreinholdtsen/meshfx-node">meshfx-node</a>
 405 and a script
 406 <a href="https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node">build-rpi-mesh-node</a>
 407 to create the Raspberry Pi boot image.  I'm using Debian Jessie (and
 408 not Raspbian), to get more control over the packages available.
 409 Unfortunately a huge binary blob need to be inserted into the boot
 410 image to get it booting, but I'll ignore that for now.  Also, as
 411 Debian lack support for the CPU features available in the Raspberry
 412 Pi, the system do not use the hardware floating point unit.  I hope
 413 the routing performance isn't affected by the lack of hardware FPU
 414 support.</p>
 415
 416 <p>To create an image, run the following with a sudo enabled user
 417 after inserting the target SD card into the build machine:</p>
 418
 419 <p><pre>
 420 % wget -O build-rpi-mesh-node \
 421     https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
 422 % sudo bash -x ./build-rpi-mesh-node > build.log 2>&1
 423 % dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
 424 %
 425 </pre></p>
 426
 427 <p>Booting with the resulting SD card on a Raspberry PI with a USB
 428 wifi card inserted should give you a mesh node.  At least it does for
 429 me with a the wifi card I am using. The default mesh settings are the
 430 ones used by the Oslo mesh project at Hackeriet, as I mentioned in
 431 <a href="http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html">an
 432 earlier blog post about this mesh testing</a>.</p>
 433
 434 <p>The mesh node was not horribly expensive either.  I bought
 435 everything over the counter in shops nearby.  If I had ordered online
 436 from the lowest bidder, the price should be significantly lower:</p>
 437
 438 <p><table>
 439
 440 <tr><th>Supplier</th><th>Model</th><th>NOK</th></tr>
 441 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi model B</td><td>349.90</td></tr>
 442 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi type B case</td><td>99.90</td></tr>
 443 <tr><td>Lefdal</td><td>Jensen Air:Link 25150</td><td>295.-</td></tr>
 444 <tr><td>Clas Ohlson</td><td>Kingston 16 GB SD card</td><td>199.-</td></tr>
 445 <tr><td>Total cost</td><td></td><td>943.80</td></tr>
 446
 447 </table></p>
 448
 449 <p>Now my mesh network at home consist of one laptop in the basement
 450 connected to my production network, one Raspberry Pi node on the 1th
 451 floor that can be seen by my neighbor across the park, and one
 452 play-node I use to develop the image building script.  And some times
 453 I hook up my work horse laptop to the mesh to test it.  I look forward
 454 to figuring out what kind of latency the batman-adv setup will give,
 455 and how much packet loss we will experience around the park. :)</p>

 476         <p>Wireless mesh networks are self organising and self healing
 477 networks that can be used to connect computers across small and large
 478 areas, depending on the radio technology used.  Normal wifi equipment
 479 can be used to create home made radio networks, and there are several
 480 successful examples like
 481 <a href="http://www.freifunk.net/">Freifunk</a> and
 482 <a href="http://www.awmn.net/">Athens Wireless Metropolitan Network</a>
 483 (see
 484 <a href="http://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region#Greece">wikipedia
 485 for a large list</a>) around the globe.  To give you an idea how it
 486 work, check out the nice overview of the Kiel Freifunk community which
 487 can be seen from their
 488 <a href="http://freifunk.in-kiel.de/ffmap/nodes.html">dynamically
 489 updated node graph and map</a>, where one can see how the mesh nodes
 490 automatically handle routing and recover from nodes disappearing.
 491 There is also a small community mesh network group in Oslo, Norway,
 492 and that is the main topic of this blog post.</p>
 493
 494 <p>I've wanted to check out mesh networks for a while now, and hoped
 495 to do it as part of my involvement with the <a
 496 href="http://www.nuug.no/">NUUG member organisation</a> community, and
 497 my recent involvement in
 498 <a href="https://wiki.debian.org/FreedomBox">the Freedombox project</a>
 499 finally lead me to give mesh networks some priority, as I suspect a
 500 Freedombox should use mesh networks to connect neighbours and family
 501 when possible, given that most communication between people are
 502 between those nearby (as shown for example by research on Facebook
 503 communication patterns).  It also allow people to communicate without
 504 any central hub to tap into for those that want to listen in on the
 505 private communication of citizens, which have become more and more
 506 important over the years.</p>
 507
 508 <p>So far I have only been able to find one group of people in Oslo
 509 working on community mesh networks, over at the hack space
 510 <a href="http://hackeriet.no/">Hackeriet</a> at Husmania.  They seem to
 511 have started with some Freifunk based effort using OLSR, called
 512 <a href="http://oslo.freifunk.net/index.php?title=Main_Page">the Oslo
 513 Freifunk project</a>, but that effort is now dead and the people
 514 behind it have moved on to a batman-adv based system called
 515 <a href="http://meshfx.org/trac">meshfx</a>.  Unfortunately the wiki
 516 site for the Oslo Freifunk project is no longer possible to update to
 517 reflect this fact, so the old project page can't be updated to point to
 518 the new project.  A while back, the people at Hackeriet invited people
 519 from the Freifunk community to Oslo to talk about mesh networks.  I
 520 came across this video where Hans Jørgen Lysglimt interview the
 521 speakers about this talk (from
 522 <a href="https://www.youtube.com/watch?v=N2Kd7CLkhSY">youtube</a>):</p>
 523
 524 <p><iframe width="420" height="315" src="https://www.youtube.com/embed/N2Kd7CLkhSY" frameborder="0" allowfullscreen></iframe></p>
 525
 526 <p>I mentioned OLSR and batman-adv, which are mesh routing protocols.
 527 There are heaps of different protocols, and I am still struggling to
 528 figure out which one would be "best" for some definitions of best, but
 529 given that the community mesh group in Oslo is so small, I believe it
 530 is best to hook up with the existing one instead of trying to create a
 531 completely different setup, and thus I have decided to focus on
 532 batman-adv for now.  It sure help me to  know that the very cool
 533 <a href="http://www.servalproject.org/">Serval project in Australia</a>
 534 is using batman-adv as their meshing technology when it create a self
 535 organizing and self healing telephony system for disaster areas and
 536 less industrialized communities.  Check out this cool video presenting
 537 that project (from
 538 <a href="https://www.youtube.com/watch?v=30qNfzJCQOA">youtube</a>):</p>
 539
 540 <p><iframe width="560" height="315" src="https://www.youtube.com/embed/30qNfzJCQOA" frameborder="0" allowfullscreen></iframe></p>
 541
 542 <p>According to the wikipedia page on
 543 <a href="http://en.wikipedia.org/wiki/Wireless_mesh_network">Wireless
 544 mesh network</a> there are around 70 competing schemes for routing
 545 packets across mesh networks, and OLSR, B.A.T.M.A.N. and
 546 B.A.T.M.A.N. advanced are protocols used by several free software
 547 based community mesh networks.</p>
 548
 549 <p>The batman-adv protocol is a bit special, as it provide layer 2
 550 (as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same
 551 network.  One way to think about it is that it provide a mesh based
 552 vlan you can bridge to or handle like any other vlan connected to your
 553 computer.  The required drivers are already in the Linux kernel at
 554 least since Debian Wheezy, and it is fairly easy to set up.  A
 555 <a href="http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide">good
 556 introduction</a> is available from the Open Mesh project.  These are
 557 the key settings needed to join the Oslo meshfx network:</p>
 558
 559 <p><table>
 560 <tr><th>Setting</th><th>Value</th></tr>
 561 <tr><td>Protocol / kernel module</td><td>batman-adv</td></tr>
 562 <tr><td>ESSID</td><td>meshfx@hackeriet</td></tr>
 563 <td>Channel / Frequency</td><td>11 / 2462</td></tr>
 564 <td>Cell ID</td><td>02:BA:00:00:00:01</td>
 565 </table></p>
 566
 567 <p>The reason for setting ad-hoc wifi Cell ID is to work around bugs
 568 in firmware used in wifi card and wifi drivers.  (See a nice post from
 569 VillageTelco about
 570 "<a href="http://tiebing.blogspot.no/2009/12/ad-hoc-cell-splitting-re-post-original.html">Information
 571 about cell-id splitting, stuck beacons, and failed IBSS merges!</a>
 572 for details.)  When these settings are activated and you have some
 573 other mesh node nearby, your computer will be connected to the mesh
 574 network and can communicate with any mesh node that is connected to
 575 any of the nodes in your network of nodes. :)</p>
 576
 577 <p>My initial plan was to reuse my old Linksys WRT54GL as a mesh node,
 578 but that seem to be very hard, as I have not been able to locate a
 579 firmware supporting batman-adv.  If anyone know how to use that old
 580 wifi access point with batman-adv these days, please let me know.</p>
 581
 582 <p>If you find this project interesting and want to join, please join
 583 us on IRC, either channel
 584 <a href="irc://irc.freenode.net/#oslohackerspace">#oslohackerspace</a>
 585 or <a href="irc://irc.freenode.net/#nuug">#nuug</a> on
 586 irc.freenode.net.</p>
 587
 588 <p>While investigating mesh networks in Oslo, I came across an old
 589 research paper from the university of Stavanger and Telenor Research
 590 and Innovation called
 591 <a href="http://folk.uio.no/paalee/publications/netrel-egeland-iswcs-2008.pdf">The
 592 reliability of wireless backhaul mesh networks</a> and elsewhere
 593 learned that Telenor have been experimenting with mesh networks at
 594 Grünerløkka in Oslo.  So mesh networks are also interesting for
 595 commercial companies, even though Telenor discovered that it was hard
 596 to figure out a good business plan for mesh networking and as far as I
 597 know have closed down the experiment.  Perhaps Telenor or others would
 598 be interested in a cooperation?</p>
 599
 600 <p><strong>Update 2013-10-12</strong>: I was just
 601 <a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2013-October/005900.html">told
 602 by the Serval project developers</a> that they no longer use
 603 batman-adv (but are compatible with it), but their own crypto based
 604 mesh system.</p>

 702       </div>
 703       <div class="body">
 704         <p>I was introduced to the
 705 <a href="http://www.freedomboxfoundation.org/">Freedombox project</a>
 706 in 2010, when Eben Moglen presented his vision about serving the need
 707 of non-technical people to keep their personal information private and
 708 within the legal protection of their own homes.  The idea is to give
 709 people back the power over their network and machines, and return
 710 Internet back to its intended peer-to-peer architecture.  Instead of
 711 depending on a central service, the Freedombox will give everyone
 712 control over their own basic infrastructure.</p>
 713
 714 <p>I've intended to join the effort since then, but other tasks have
 715 taken priority.  But this summers nasty news about the misuse of trust
 716 and privilege exercised by the "western" intelligence gathering
 717 communities increased my eagerness to contribute to a point where I
 718 actually started working on the project a while back.</p>
 719
 720 <p>The <a href="https://alioth.debian.org/projects/freedombox/">initial
 721 Debian initiative</a> based on the vision from Eben Moglen, is to
 722 create a simple and cheap Debian based appliance that anyone can hook
 723 up in their home and get access to secure and private services and
 724 communication.  The initial deployment platform have been the
 725 <a href="http://www.globalscaletechnologies.com/t-dreamplugdetails.aspx">Dreamplug</a>,
 726 which is a piece of hardware I do not own.  So to be able to test what
 727 the current Freedombox setup look like, I had to come up with a way to install
 728 it on some hardware I do have access to.  I have rewritten the
 729 <a href="https://github.com/NickDaly/freedom-maker">freedom-maker</a>
 730 image build framework to use .deb packages instead of only copying
 731 setup into the boot images, and thanks to this rewrite I am able to
 732 set up any machine supported by Debian Wheezy as a Freedombox, using
 733 the previously mentioned deb (and a few support debs for packages
 734 missing in Debian).</p>
 735
 736 <p>The current Freedombox setup consist of a set of bootstrapping
 737 scripts
 738 (<a href="https://github.com/petterreinholdtsen/freedombox-setup">freedombox-setup</a>),
 739 and a administrative web interface
 740 (<a href="https://github.com/NickDaly/Plinth">plinth</a> + exmachina +
 741 withsqlite), as well as a privacy enhancing proxy based on
 742 <a href="http://packages.qa.debian.org/privoxy">privoxy</a>
 743 (freedombox-privoxy).  There is also a web/javascript based XMPP
 744 client (<a href="http://packages.qa.debian.org/jwchat">jwchat</a>)
 745 trying (unsuccessfully so far) to talk to the XMPP server
 746 (<a href="http://packages.qa.debian.org/ejabberd">ejabberd</a>).  The
 747 web interface is pluggable, and the goal is to use it to enable OpenID
 748 services, mesh network connectivity, use of TOR, etc, etc.  Not much of
 749 this is really working yet, see
 750 <a href="https://github.com/NickDaly/freedombox-todos/blob/master/TODO">the
 751 project TODO</a> for links to GIT repositories.  Most of the code is
 752 on github at the moment.  The HTTP proxy is operational out of the
 753 box, and the admin web interface can be used to add/remove plinth
 754 users.  I've not been able to do anything else with it so far, but
 755 know there are several branches spread around github and other places
 756 with lots of half baked features.</p>
 757
 758 <p>Anyway, if you want to have a look at the current state, the
 759 following recipes should work to give you a test machine to poke
 760 at.</p>
 761
 762 <p><strong>Debian Wheezy amd64</strong></p>
 763
 764 <ol>
 765
 766 <li>Fetch normal Debian Wheezy installation ISO.</li>
 767 <li>Boot from it, either as CD or USB stick.</li>
 768 <li><p>Press [tab] on the boot prompt and add this as a boot argument
 769 to the Debian installer:<p>
 770 <pre>url=<a href="http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat">http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat</a></pre></li>
 771
 772 <li>Answer the few language/region/password questions and pick disk to
 773 install on.</li>
 774
 775 <li>When the installation is finished and the machine have rebooted a
 776 few times, your Freedombox is ready for testing.</li>
 777
 778 </ol>
 779
 780 <p><strong>Raspberry Pi Raspbian</strong></p>
 781
 782 <ol>
 783
 784 <li>Fetch a Raspbian SD card image, create SD card.</li>
 785 <li>Boot from SD card, extend file system to fill the card completely.</li>
 786 <li><p>Log in and add this to /etc/sources.list:</p>
 787 <pre>
 788 deb <a href="http://www.reinholdtsen.name/freedombox/">http://www.reinholdtsen.name/freedombox</a> wheezy main
 789 </pre></li>
 790 <li><p>Run this as root:</p>
 791 <pre>
 792 wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
 793    apt-key add -
 794 apt-get update
 795 apt-get install freedombox-setup
 796 /usr/lib/freedombox/setup
 797 </pre></li>
 798 <li>Reboot into your freshly created Freedombox.</li>
 799
 800 </ol>
 801
 802 <p>You can test it on other architectures too, but because the
 803 freedombox-privoxy package is binary, it will only work as intended on
 804 the architectures where I have had time to build the binary and put it
 805 in my APT repository.  But do not let this stop you.  It is only a
 806 short "<tt>apt-get source -b freedombox-privoxy</tt>" away. :)</p>
 807
 808 <p>Note that by default Freedombox is a DHCP server on the
 809 192.168.1.0/24 subnet, so if this is your subnet be careful and turn
 810 off the DHCP server by running "<tt>update-rc.d isc-dhcp-server
 811 disable</tt>" as root.</p>
 812
 813 <p>Please let me know if this works for you, or if you have any
 814 problems.  We gather on the IRC channel
 815 <a href="irc://irc.debian.org:6667/%23freedombox">#freedombox</a> on
 816 irc.debian.org and the
 817 <a href="http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss">project
 818 mailing list</a>.</p>
 819
 820 <p>Once you get your freedombox operational, you can visit
 821 <tt>http://your-host-name:8001/</tt> to see the state of the plint
 822 welcome screen (dead end - do not be surprised if you are unable to
 823 get past it), and next visit <tt>http://your-host-name:8001/help/</tt>
 824 to look at the rest of plinth.  The default user is 'admin' and the
 825 default password is 'secret'.</p>
