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

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

 230         21st October 2013
 231       </div>
 232       <div class="body">
 233         <p>The last few days I have been experimenting with
 234 <a href="http://www.open-mesh.org/projects/batman-adv/wiki">the
 235 batman-adv mesh technology</a>.  I want to gain some experience to see
 236 if it will fit <a href="https://wiki.debian.org/FreedomBox">the
 237 Freedombox project</a>, and together with my neighbors try to build a
 238 mesh network around the park where I live.  Batman-adv is a layer 2
 239 mesh system ("ethernet" in other words), where the mesh network appear
 240 as if all the mesh clients are connected to the same switch.</p>
 241
 242 <p>My hardware of choice was the Linksys WRT54GL routers I had lying
 243 around, but I've been unable to get them working with batman-adv.  So
 244 instead, I started playing with a
 245 <a href="http://www.raspberrypi.org/">Raspberry Pi</a>, and tried to
 246 get it working as a mesh node.  My idea is to use it to create a mesh
 247 node which function as a switch port, where everything connected to
 248 the Raspberry Pi ethernet plug is connected (bridged) to the mesh
 249 network.  This allow me to hook a wifi base station like the Linksys
 250 WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
 251 non-mesh clients to hook up to the mesh.  This in turn is useful for
 252 Android phones using <a href="http://servalproject.org/">the Serval
 253 Project</a> voip client, allowing every one around the playground to
 254 phone and message each other for free.  The reason is that Android
 255 phones do not see ad-hoc wifi networks (they are filtered away from
 256 the GUI view), and can not join the mesh without being rooted.  But if
 257 they are connected using a normal wifi base station, they can talk to
 258 every client on the local network.</p>
 259
 260 <p>To get this working, I've created a debian package
 261 <a href="https://github.com/petterreinholdtsen/meshfx-node">meshfx-node</a>
 262 and a script
 263 <a href="https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node">build-rpi-mesh-node</a>
 264 to create the Raspberry Pi boot image.  I'm using Debian Jessie (and
 265 not Raspbian), to get more control over the packages available.
 266 Unfortunately a huge binary blob need to be inserted into the boot
 267 image to get it booting, but I'll ignore that for now.  Also, as
 268 Debian lack support for the CPU features available in the Raspberry
 269 Pi, the system do not use the hardware floating point unit.  I hope
 270 the routing performance isn't affected by the lack of hardware FPU
 271 support.</p>
 272
 273 <p>To create an image, run the following with a sudo enabled user
 274 after inserting the target SD card into the build machine:</p>
 275
 276 <p><pre>
 277 % wget -O build-rpi-mesh-node \
 278     https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
 279 % sudo bash -x ./build-rpi-mesh-node > build.log 2>&1
 280 % dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
 281 %
 282 </pre></p>
 283
 284 <p>Booting with the resulting SD card on a Raspberry PI with a USB
 285 wifi card inserted should give you a mesh node.  At least it does for
 286 me with a the wifi card I am using. The default mesh settings are the
 287 ones used by the Oslo mesh project at Hackeriet, as I mentioned in
 288 <a href="http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html">an
 289 earlier blog post about this mesh testing</a>.</p>
 290
 291 <p>The mesh node was not horribly expensive either.  I bought
 292 everything over the counter in shops nearby.  If I had ordered online
 293 from the lowest bidder, the price should be significantly lower:</p>
 294
 295 <p><table>
 296
 297 <tr><th>Supplier</th><th>Model</th><th>NOK</th></tr>
 298 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi model B</td><td>349.90</td></tr>

 302 <tr><td>Total cost</td><td></td><td>943.80</td></tr>
 303
 304 </table></p>
 305
 306 <p>Now my mesh network at home consist of one laptop in the basement
 307 connected to my production network, one Raspberry Pi node on the 1th
 308 floor that can be seen by my neighbor across the park, and one
 309 play-node I use to develop the image building script.  And some times
 310 I hook up my work horse laptop to the mesh to test it.  I look forward
 311 to figuring out what kind of latency the batman-adv setup will give,
 312 and how much packet loss we will experience around the park. :)</p>

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

 398
 399 <p>According to the wikipedia page on
 400 <a href="http://en.wikipedia.org/wiki/Wireless_mesh_network">Wireless
 401 mesh network</a> there are around 70 competing schemes for routing
 402 packets across mesh networks, and OLSR, B.A.T.M.A.N. and
 403 B.A.T.M.A.N. advanced are protocols used by several free software
 404 based community mesh networks.</p>

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

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

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