  31         <p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
  32 project</a> is working on providing the software and hardware for
  33 making it easy for non-technical people to host their data and
  34 communication at home, and being able to communicate with their
  35 friends and family encrypted and away from prying eyes.  It has been
  36 going on for a while, and is slowly progressing towards a new test
  37 release (0.2).</p>
  38
  39 <p>And what day could be better than the Pi day to announce that the
  40 new version will provide "hard drive" / SD card / USB stick images for
  41 Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
  42 system), and can also be installed using a Debian installer preseed
  43 file.  The Debian based Freedombox is now based on Debian Jessie,
  44 where most of the needed packages used are already present.  Only one,
  45 the freedombox-setup package, is missing.  To try to build your own
  46 boot image to test the current status, fetch the freedom-maker scripts
  47 and build using
  48 <a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
  49 with a user with sudo access to become root:
  50
  51 <pre>
  52 git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
  53   freedom-maker
  54 sudo apt-get install git vmdebootstrap mercurial python-docutils \
  55   mktorrent extlinux virtualbox qemu-user-static binfmt-support \
  56   u-boot-tools
  57 make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
  58 </pre>
  59
  60 <p>Root access is needed to run debootstrap and mount loopback
  61 devices.  See the README for more details on the build. If you do not
  62 want all three images, trim the make line.  But note that thanks to <a
  63 href="https://bugs.debian.org/741407">a race condition in
  64 vmdebootstrap</a>, the build might fail without the patch to the
  65 kpartx call.</p>
  66
  67 <p>If you instead want to install using a Debian CD and the preseed
  68 method, boot a Debian Wheezy ISO and use this boot argument to load
  69 the preseed values:</p>
  70
  71 <pre>
  72 url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
  73 </pre>
  74
  75 <p>But note that due to <a href="https://bugs.debian.org/740673">a
  76 recently introduced bug in apt in Jessie</a>, the installer will
  77 currently hang while setting up APT sources.  Killing the
  78 '<tt>apt-cdrom ident</tt>' process when it hang a few times during the
  79 installation will get the installation going.  This affect all
  80 installations in Jessie, and I expect it will be fixed soon.</p>
  81
  82 Give it a go and let us know how it goes on the mailing list, and help
  83 us get the new release published. :) Please join us on
  84 <a href="irc://irc.debian.org:6667/%23freedombox">IRC (#freedombox on

 108         <p>The
 109 <a href="http://packages.qa.debian.org/v/vmdebootstrap.html">vmdebootstrap</a>
 110 program is a a very nice system to create virtual machine images.  It
 111 create a image file, add a partition table, mount it and run
 112 debootstrap in the mounted directory to create a Debian system on a
 113 stick.  Yesterday, I decided to try to teach it how to make images for
 114 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi</a>, as part
 115 of a plan to simplify the build system for
 116 <a href="https://wiki.debian.org/FreedomBox">the FreedomBox
 117 project</a>.  The FreedomBox project already uses vmdebootstrap for
 118 the virtualbox images, but its current build system made multistrap
 119 based system for Dreamplug images, and it is lacking support for
 120 Raspberry Pi.</p>
 121
 122 <p>Armed with the knowledge on how to build "foreign" (aka non-native
 123 architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
 124 code and adjusted it to be able to build armel images on my amd64
 125 Debian laptop.  I ended up giving vmdebootstrap five new options,
 126 allowing me to replicate the image creation process I use to make
 127 <a href="http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html">Debian
 128 Jessie based mesh node images for the Raspberry Pi</a>.  First, the
 129 <tt>--foreign /path/to/binfm_handler</tt> option tell vmdebootstrap to
 130 call debootstrap with --foreign and to copy the handler into the
 131 generated chroot before running the second stage.  This allow
 132 vmdebootstrap to create armel images on an amd64 host.  Next I added
 133 two new options <tt>--bootsize size</tt> and <tt>--boottype
 134 fstype</tt> to teach it to create a separate /boot/ partition with the
 135 given file system type, allowing me to create an image with a vfat
 136 partition for the /boot/ stuff.  I also added a <tt>--variant
 137 variant</tt> option to allow me to create smaller images without the
 138 Debian base system packages installed.  Finally, I added an option
 139 <tt>--no-extlinux</tt> to tell vmdebootstrap to not install extlinux
 140 as a boot loader.  It is not needed on the Raspberry Pi and probably
 141 most other non-x86 architectures.  The changes were accepted by the
 142 upstream author of vmdebootstrap yesterday and today, and is now
 143 available from
 144 <a href="http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/">the
 145 upstream project page</a>.</p>
 146
 147 <p>To use it to build a Raspberry Pi image using Debian Jessie, first
 148 create a small script (the customize script) to add the non-free
 149 binary blob needed to boot the Raspberry Pi and the APT source
 150 list:</p>
 151
 152 <p><pre>
 153 #!/bin/sh
 154 set -e # Exit on first error
 155 rootdir="$1"
 156 cd "$rootdir"
 157 cat &lt;&lt;EOF > etc/apt/sources.list
 158 deb http://http.debian.net/debian/ jessie main contrib non-free
 159 EOF
 160 # Install non-free binary blob needed to boot Raspberry Pi.  This
 161 # install a kernel somewhere too.
 162 wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
 163     -O $rootdir/usr/bin/rpi-update
 164 chmod a+x $rootdir/usr/bin/rpi-update
 165 mkdir -p $rootdir/lib/modules
 166 touch $rootdir/boot/start.elf
 167 chroot $rootdir rpi-update
 168 </pre></p>
 169
 170 <p>Next, fetch the latest vmdebootstrap script and call it like this
 171 to build the image:</p>
 172
 173 <pre>
 174 sudo ./vmdebootstrap \
 175     --variant minbase \
 176     --arch armel \
 177     --distribution jessie \
 178     --mirror http://http.debian.net/debian \
 179     --image test.img \
 180     --size 600M \
 181     --bootsize 64M \
 182     --boottype vfat \
 183     --log-level debug \
 184     --verbose \
 185     --no-kernel \
 186     --no-extlinux \
 187     --root-password raspberry \
 188     --hostname raspberrypi \
 189     --foreign /usr/bin/qemu-arm-static \
 190     --customize `pwd`/customize \
 191     --package netbase \
 192     --package git-core \
 193     --package binutils \
 194     --package ca-certificates \
 195     --package wget \
 196     --package kmod
 197 </pre></p>
 198
 199 <p>The list of packages being installed are the ones needed by
 200 rpi-update to make the image bootable on the Raspberry Pi, with the
 201 exception of netbase, which is needed by debootstrap to find
 202 /etc/hosts with the minbase variant.  I really wish there was a way to
 203 set up an Raspberry Pi using only packages in the Debian archive, but
 204 that is not possible as far as I know, because it boots from the GPU
 205 using a non-free binary blob.</p>
 206
 207 <p>The build host need debootstrap, kpartx and qemu-user-static and
 208 probably a few others installed.  I have not checked the complete
 209 build dependency list.</p>
 210
 211 <p>The resulting image will not use the hardware floating point unit
 212 on the Raspberry PI, because the armel architecture in Debian is not
 213 optimized for that use.  So the images created will be a bit slower
 214 than <a href="http://www.raspbian.org/">Raspbian</a> based images.</p>

 231       <div class="date">
 232         21st October 2013
 233       </div>
 234       <div class="body">
 235         <p>The last few days I have been experimenting with
 236 <a href="http://www.open-mesh.org/projects/batman-adv/wiki">the
 237 batman-adv mesh technology</a>.  I want to gain some experience to see
 238 if it will fit <a href="https://wiki.debian.org/FreedomBox">the
 239 Freedombox project</a>, and together with my neighbors try to build a
 240 mesh network around the park where I live.  Batman-adv is a layer 2
 241 mesh system ("ethernet" in other words), where the mesh network appear
 242 as if all the mesh clients are connected to the same switch.</p>
 243
 244 <p>My hardware of choice was the Linksys WRT54GL routers I had lying
 245 around, but I've been unable to get them working with batman-adv.  So
 246 instead, I started playing with a
 247 <a href="http://www.raspberrypi.org/">Raspberry Pi</a>, and tried to
 248 get it working as a mesh node.  My idea is to use it to create a mesh
 249 node which function as a switch port, where everything connected to
 250 the Raspberry Pi ethernet plug is connected (bridged) to the mesh
 251 network.  This allow me to hook a wifi base station like the Linksys
 252 WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
 253 non-mesh clients to hook up to the mesh.  This in turn is useful for
 254 Android phones using <a href="http://servalproject.org/">the Serval
 255 Project</a> voip client, allowing every one around the playground to
 256 phone and message each other for free.  The reason is that Android
 257 phones do not see ad-hoc wifi networks (they are filtered away from
 258 the GUI view), and can not join the mesh without being rooted.  But if
 259 they are connected using a normal wifi base station, they can talk to
 260 every client on the local network.</p>
 261
 262 <p>To get this working, I've created a debian package
 263 <a href="https://github.com/petterreinholdtsen/meshfx-node">meshfx-node</a>
 264 and a script
 265 <a href="https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node">build-rpi-mesh-node</a>
 266 to create the Raspberry Pi boot image.  I'm using Debian Jessie (and
 267 not Raspbian), to get more control over the packages available.
 268 Unfortunately a huge binary blob need to be inserted into the boot
 269 image to get it booting, but I'll ignore that for now.  Also, as
 270 Debian lack support for the CPU features available in the Raspberry
 271 Pi, the system do not use the hardware floating point unit.  I hope
 272 the routing performance isn't affected by the lack of hardware FPU
 273 support.</p>
 274
 275 <p>To create an image, run the following with a sudo enabled user
 276 after inserting the target SD card into the build machine:</p>
 277
 278 <p><pre>
 279 % wget -O build-rpi-mesh-node \
 280     https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
 281 % sudo bash -x ./build-rpi-mesh-node > build.log 2>&1
 282 % dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
 283 %
 284 </pre></p>
 285
 286 <p>Booting with the resulting SD card on a Raspberry PI with a USB
 287 wifi card inserted should give you a mesh node.  At least it does for
 288 me with a the wifi card I am using. The default mesh settings are the
 289 ones used by the Oslo mesh project at Hackeriet, as I mentioned in
 290 <a href="http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html">an
 291 earlier blog post about this mesh testing</a>.</p>
 292
 293 <p>The mesh node was not horribly expensive either.  I bought
 294 everything over the counter in shops nearby.  If I had ordered online
 295 from the lowest bidder, the price should be significantly lower:</p>
 296
 297 <p><table>
 298

 300 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi model B</td><td>349.90</td></tr>

 304 <tr><td>Total cost</td><td></td><td>943.80</td></tr>
 305
 306 </table></p>
 307
 308 <p>Now my mesh network at home consist of one laptop in the basement
 309 connected to my production network, one Raspberry Pi node on the 1th
 310 floor that can be seen by my neighbor across the park, and one
 311 play-node I use to develop the image building script.  And some times
 312 I hook up my work horse laptop to the mesh to test it.  I look forward
 313 to figuring out what kind of latency the batman-adv setup will give,
 314 and how much packet loss we will experience around the park. :)</p>

 335         <p>Wireless mesh networks are self organising and self healing
 336 networks that can be used to connect computers across small and large
 337 areas, depending on the radio technology used.  Normal wifi equipment
 338 can be used to create home made radio networks, and there are several
 339 successful examples like
 340 <a href="http://www.freifunk.net/">Freifunk</a> and
 341 <a href="http://www.awmn.net/">Athens Wireless Metropolitan Network</a>
 342 (see
 343 <a href="http://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region#Greece">wikipedia
 344 for a large list</a>) around the globe.  To give you an idea how it
 345 work, check out the nice overview of the Kiel Freifunk community which
 346 can be seen from their
 347 <a href="http://freifunk.in-kiel.de/ffmap/nodes.html">dynamically
 348 updated node graph and map</a>, where one can see how the mesh nodes
 349 automatically handle routing and recover from nodes disappearing.
 350 There is also a small community mesh network group in Oslo, Norway,
 351 and that is the main topic of this blog post.</p>
 352
 353 <p>I've wanted to check out mesh networks for a while now, and hoped
 354 to do it as part of my involvement with the <a
 355 href="http://www.nuug.no/">NUUG member organisation</a> community, and
 356 my recent involvement in
 357 <a href="https://wiki.debian.org/FreedomBox">the Freedombox project</a>
 358 finally lead me to give mesh networks some priority, as I suspect a
 359 Freedombox should use mesh networks to connect neighbours and family
 360 when possible, given that most communication between people are
 361 between those nearby (as shown for example by research on Facebook
 362 communication patterns).  It also allow people to communicate without
 363 any central hub to tap into for those that want to listen in on the
 364 private communication of citizens, which have become more and more
 365 important over the years.</p>
 366
 367 <p>So far I have only been able to find one group of people in Oslo
 368 working on community mesh networks, over at the hack space
 369 <a href="http://hackeriet.no/">Hackeriet</a> at Husmania.  They seem to
 370 have started with some Freifunk based effort using OLSR, called
 371 <a href="http://oslo.freifunk.net/index.php?title=Main_Page">the Oslo
 372 Freifunk project</a>, but that effort is now dead and the people
 373 behind it have moved on to a batman-adv based system called
 374 <a href="http://meshfx.org/trac">meshfx</a>.  Unfortunately the wiki
 375 site for the Oslo Freifunk project is no longer possible to update to
 376 reflect this fact, so the old project page can't be updated to point to
 377 the new project.  A while back, the people at Hackeriet invited people
 378 from the Freifunk community to Oslo to talk about mesh networks.  I
 379 came across this video where Hans Jørgen Lysglimt interview the
 380 speakers about this talk (from
 381 <a href="https://www.youtube.com/watch?v=N2Kd7CLkhSY">youtube</a>):</p>
 382
 383 <p><iframe width="420" height="315" src="https://www.youtube.com/embed/N2Kd7CLkhSY" frameborder="0" allowfullscreen></iframe></p>
 384
 385 <p>I mentioned OLSR and batman-adv, which are mesh routing protocols.
 386 There are heaps of different protocols, and I am still struggling to
 387 figure out which one would be "best" for some definitions of best, but
 388 given that the community mesh group in Oslo is so small, I believe it
 389 is best to hook up with the existing one instead of trying to create a
 390 completely different setup, and thus I have decided to focus on
 391 batman-adv for now.  It sure help me to  know that the very cool
 392 <a href="http://www.servalproject.org/">Serval project in Australia</a>
 393 is using batman-adv as their meshing technology when it create a self
 394 organizing and self healing telephony system for disaster areas and
 395 less industrialized communities.  Check out this cool video presenting
 396 that project (from
 397 <a href="https://www.youtube.com/watch?v=30qNfzJCQOA">youtube</a>):</p>

 401 <p>According to the wikipedia page on
 402 <a href="http://en.wikipedia.org/wiki/Wireless_mesh_network">Wireless
 403 mesh network</a> there are around 70 competing schemes for routing
 404 packets across mesh networks, and OLSR, B.A.T.M.A.N. and
 405 B.A.T.M.A.N. advanced are protocols used by several free software
 406 based community mesh networks.</p>
 407
 408 <p>The batman-adv protocol is a bit special, as it provide layer 2
 409 (as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same
 410 network.  One way to think about it is that it provide a mesh based
 411 vlan you can bridge to or handle like any other vlan connected to your
 412 computer.  The required drivers are already in the Linux kernel at
 413 least since Debian Wheezy, and it is fairly easy to set up.  A
 414 <a href="http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide">good
 415 introduction</a> is available from the Open Mesh project.  These are
 416 the key settings needed to join the Oslo meshfx network:</p>
 417
 418 <p><table>
 419 <tr><th>Setting</th><th>Value</th></tr>
 420 <tr><td>Protocol / kernel module</td><td>batman-adv</td></tr>
 421 <tr><td>ESSID</td><td>meshfx@hackeriet</td></tr>
 422 <td>Channel / Frequency</td><td>11 / 2462</td></tr>
 423 <td>Cell ID</td><td>02:BA:00:00:00:01</td>
 424 </table></p>
 425
 426 <p>The reason for setting ad-hoc wifi Cell ID is to work around bugs
 427 in firmware used in wifi card and wifi drivers.  (See a nice post from
 428 VillageTelco about
 429 "<a href="http://tiebing.blogspot.no/2009/12/ad-hoc-cell-splitting-re-post-original.html">Information
 430 about cell-id splitting, stuck beacons, and failed IBSS merges!</a>
 431 for details.)  When these settings are activated and you have some
 432 other mesh node nearby, your computer will be connected to the mesh
 433 network and can communicate with any mesh node that is connected to
 434 any of the nodes in your network of nodes. :)</p>
 435
 436 <p>My initial plan was to reuse my old Linksys WRT54GL as a mesh node,
 437 but that seem to be very hard, as I have not been able to locate a
 438 firmware supporting batman-adv.  If anyone know how to use that old
 439 wifi access point with batman-adv these days, please let me know.</p>
 440
 441 <p>If you find this project interesting and want to join, please join
 442 us on IRC, either channel
 443 <a href="irc://irc.freenode.net/#oslohackerspace">#oslohackerspace</a>
 444 or <a href="irc://irc.freenode.net/#nuug">#nuug</a> on
 445 irc.freenode.net.</p>
 446
 447 <p>While investigating mesh networks in Oslo, I came across an old
 448 research paper from the university of Stavanger and Telenor Research
 449 and Innovation called
 450 <a href="http://folk.uio.no/paalee/publications/netrel-egeland-iswcs-2008.pdf">The
 451 reliability of wireless backhaul mesh networks</a> and elsewhere
 452 learned that Telenor have been experimenting with mesh networks at
 453 Grünerløkka in Oslo.  So mesh networks are also interesting for
 454 commercial companies, even though Telenor discovered that it was hard
 455 to figure out a good business plan for mesh networking and as far as I
 456 know have closed down the experiment.  Perhaps Telenor or others would
 457 be interested in a cooperation?</p>
 458
 459 <p><strong>Update 2013-10-12</strong>: I was just
 460 <a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2013-October/005900.html">told
 461 by the Serval project developers</a> that they no longer use
 462 batman-adv (but are compatible with it), but their own crypto based
 463 mesh system.</p>

 532 <p>On other news, I am happy to report that Freedombox based on Debian
 533 Jessie is coming along quite well, and soon both Owncloud and using
 534 Tor should be available for testers of the Freedombox solution. :) In
 535 a few weeks I hope everything needed to test it is included in Debian.
 536 The withsqlite package is already in Debian, and the plinth package is
 537 pending in NEW.  The third and vital part of that puzzle is the
 538 metapackage/setup framework, which is still pending an upload.  Join

 561       </div>
 562       <div class="body">
 563         <p>I was introduced to the
 564 <a href="http://www.freedomboxfoundation.org/">Freedombox project</a>
 565 in 2010, when Eben Moglen presented his vision about serving the need
 566 of non-technical people to keep their personal information private and
 567 within the legal protection of their own homes.  The idea is to give
 568 people back the power over their network and machines, and return
 569 Internet back to its intended peer-to-peer architecture.  Instead of
 570 depending on a central service, the Freedombox will give everyone
 571 control over their own basic infrastructure.</p>
 572
 573 <p>I've intended to join the effort since then, but other tasks have
 574 taken priority.  But this summers nasty news about the misuse of trust
 575 and privilege exercised by the "western" intelligence gathering
 576 communities increased my eagerness to contribute to a point where I
 577 actually started working on the project a while back.</p>
 578
 579 <p>The <a href="https://alioth.debian.org/projects/freedombox/">initial
 580 Debian initiative</a> based on the vision from Eben Moglen, is to
 581 create a simple and cheap Debian based appliance that anyone can hook
 582 up in their home and get access to secure and private services and
 583 communication.  The initial deployment platform have been the
 584 <a href="http://www.globalscaletechnologies.com/t-dreamplugdetails.aspx">Dreamplug</a>,
 585 which is a piece of hardware I do not own.  So to be able to test what
 586 the current Freedombox setup look like, I had to come up with a way to install
 587 it on some hardware I do have access to.  I have rewritten the
 588 <a href="https://github.com/NickDaly/freedom-maker">freedom-maker</a>
 589 image build framework to use .deb packages instead of only copying
 590 setup into the boot images, and thanks to this rewrite I am able to
 591 set up any machine supported by Debian Wheezy as a Freedombox, using
 592 the previously mentioned deb (and a few support debs for packages
 593 missing in Debian).</p>
 594
 595 <p>The current Freedombox setup consist of a set of bootstrapping
 596 scripts
 597 (<a href="https://github.com/petterreinholdtsen/freedombox-setup">freedombox-setup</a>),
 598 and a administrative web interface
 599 (<a href="https://github.com/NickDaly/Plinth">plinth</a> + exmachina +
 600 withsqlite), as well as a privacy enhancing proxy based on
 601 <a href="http://packages.qa.debian.org/privoxy">privoxy</a>
 602 (freedombox-privoxy).  There is also a web/javascript based XMPP
 603 client (<a href="http://packages.qa.debian.org/jwchat">jwchat</a>)
 604 trying (unsuccessfully so far) to talk to the XMPP server
 605 (<a href="http://packages.qa.debian.org/ejabberd">ejabberd</a>).  The
 606 web interface is pluggable, and the goal is to use it to enable OpenID
 607 services, mesh network connectivity, use of TOR, etc, etc.  Not much of
 608 this is really working yet, see
 609 <a href="https://github.com/NickDaly/freedombox-todos/blob/master/TODO">the
 610 project TODO</a> for links to GIT repositories.  Most of the code is
 611 on github at the moment.  The HTTP proxy is operational out of the
 612 box, and the admin web interface can be used to add/remove plinth
 613 users.  I've not been able to do anything else with it so far, but
 614 know there are several branches spread around github and other places
 615 with lots of half baked features.</p>
 616
 617 <p>Anyway, if you want to have a look at the current state, the
 618 following recipes should work to give you a test machine to poke
 619 at.</p>
 620
 621 <p><strong>Debian Wheezy amd64</strong></p>
 622
 623 <ol>
 624
 625 <li>Fetch normal Debian Wheezy installation ISO.</li>
 626 <li>Boot from it, either as CD or USB stick.</li>
 627 <li><p>Press [tab] on the boot prompt and add this as a boot argument
 628 to the Debian installer:<p>
 629 <pre>url=<a href="http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat">http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat</a></pre></li>
 630
 631 <li>Answer the few language/region/password questions and pick disk to
 632 install on.</li>
 633
 634 <li>When the installation is finished and the machine have rebooted a
 635 few times, your Freedombox is ready for testing.</li>
 636
 637 </ol>
 638
 639 <p><strong>Raspberry Pi Raspbian</strong></p>
 640
 641 <ol>
 642
 643 <li>Fetch a Raspbian SD card image, create SD card.</li>
 644 <li>Boot from SD card, extend file system to fill the card completely.</li>
 645 <li><p>Log in and add this to /etc/sources.list:</p>
 646 <pre>
 647 deb <a href="http://www.reinholdtsen.name/freedombox/">http://www.reinholdtsen.name/freedombox</a> wheezy main
 648 </pre></li>
 649 <li><p>Run this as root:</p>
 650 <pre>
 651 wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
 652    apt-key add -
 653 apt-get update
 654 apt-get install freedombox-setup
 655 /usr/lib/freedombox/setup
 656 </pre></li>
 657 <li>Reboot into your freshly created Freedombox.</li>
 658
 659 </ol>
 660
 661 <p>You can test it on other architectures too, but because the
 662 freedombox-privoxy package is binary, it will only work as intended on
 663 the architectures where I have had time to build the binary and put it
 664 in my APT repository.  But do not let this stop you.  It is only a
 665 short "<tt>apt-get source -b freedombox-privoxy</tt>" away. :)</p>
 666
 667 <p>Note that by default Freedombox is a DHCP server on the
 668 192.168.1.0/24 subnet, so if this is your subnet be careful and turn
 669 off the DHCP server by running "<tt>update-rc.d isc-dhcp-server
 670 disable</tt>" as root.</p>
 671
 672 <p>Please let me know if this works for you, or if you have any
 673 problems.  We gather on the IRC channel
 674 <a href="irc://irc.debian.org:6667/%23freedombox">#freedombox</a> on
 675 irc.debian.org and the
 676 <a href="http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss">project
 677 mailing list</a>.</p>
 678
 679 <p>Once you get your freedombox operational, you can visit
 680 <tt>http://your-host-name:8001/</tt> to see the state of the plint
 681 welcome screen (dead end - do not be surprised if you are unable to
 682 get past it), and next visit <tt>http://your-host-name:8001/help/</tt>
 683 to look at the rest of plinth.  The default user is 'admin' and the
 684 default password is 'secret'.</p>
