  24       <div class="date">27th October 2013</div>
  25       <div class="body"><p>The
  26 <a href="http://packages.qa.debian.org/v/vmdebootstrap.html">vmdebootstrap</a>
  27 program is a a very nice system to create virtual machine images.  It
  28 create a image file, add a partition table, mount it and run
  29 debootstrap in the mounted directory to create a Debian system on a
  30 stick.  Yesterday, I decided to try to teach it how to make images for
  31 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi</a>, as part
  32 of a plan to simplify the build system for the FreedomBox project.
  33 The FreedomBox project already uses vmdebootstrap for the virtualbox
  34 images, but its home made multistrap based system for Dreamplug
  35 images, and it is lacking support for Raspberry Pi.</p>
  36
  37 <p>Armed with the knowledge on how to build "foreign" (aka non-native
  38 architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
  39 code and adjusted it to be able to build armel images on my amd64
  40 Debian laptop.  I ended up giving vmdebootstrap five new options,
  41 allowing me to replicate the image creation process I use to make
  42 <a href=http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html"">Debian
  43 Jessie based mesh node images for the Raspberry Pi</a>.  First, the
  44 <tt>--foreign /path/to/binfm_handler</tt> option tell vmdebootstrap to
  45 call debootstrap with --foreign and to copy the handler into the
  46 generated chroot before running the second stage.  This allow
  47 vmdebootstrap to create armel images on an amd64 host.  Next I added
  48 two new options <tt>--bootsize size</tt> and <tt>--boottype
  49 fstype</tt> to teach it to create a separate /boot/ partition with the
  50 given file system type, allowing me to create an image with a vfat
  51 partition for the /boot/ stuff.  I also added a <tt>--variant
  52 variant</tt> option to allow me to create smaller images without the
  53 Debian base system packages installed.  Finally, I added an option
  54 <tt>--no-extlinux</tt> to tell vmdebootstrap to not install extlinux
  55 as a boot loader.  It is not needed on the Raspberry Pi and probably
  56 most other non-x86 architectures.  The changes were accepted by the
  57 upstream author of vmdebootstrap yesterday and today, and is now
  58 available from
  59 <a href="http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/">the
  60 upstream project page</a>.</p>
  61
  62 <p>To use it to build a Raspberry Pi image using Debian Jessie, first
  63 create a small script (the customize script) to add the non-free
  64 binary blob needed to boot the Raspberry Pi and the APT source
  65 list:</p>
  66
  67 <p><pre>
  68 #!/bin/sh
  69 set -e # Exit on first error
  70 rootdir="$1"
  71 cd "$rootdir"
  72 cat <<EOF > etc/apt/sources.list
  73 deb http://http.debian.net/debian/ jessie main contrib non-free
  74 EOF
  75 # Install non-free binary blob needed to boot Raspberry Pi.  This
  76 # install a kernel somewhere too.
  77 wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
  78     -O $rootdir/usr/bin/rpi-update
  79 chmod a+x $rootdir/usr/bin/rpi-update
  80 mkdir -p $rootdir/lib/modules
  81 touch $rootdir/boot/start.elf
  82 chroot $rootdir rpi-update
  83 </pre></p>
  84
  85 <p>Next, fetch the latest vmdebootstrap script and call it like this
  86 to build the image:</p>
  87
  88 <pre>
  89 sudo ./vmdebootstrap \
  90     --variant minbase \
  91     --arch armel \
  92     --distribution jessie \
  93     --mirror http://http.debian.net/debian \
  94     --image test.img \
  95     --size 600M \
  96     --bootsize 64M \
  97     --boottype vfat \
  98     --log-level debug \
  99     --verbose \
 100     --no-kernel \
 101     --no-extlinux \
 102     --root-password raspberry \
 103     --hostname raspberrypi \
 104     --foreign /usr/bin/qemu-arm-static \
 105     --customize `pwd`/customize \
 106     --package netbase \
 107     --package git-core \
 108     --package binutils \
 109     --package ca-certificates \
 110     --package wget \
 111     --package kmod
 112 </pre></p>
 113
 114 <p>The list of packages being installed are the ones needed by
 115 rpi-update to make the image bootable on the Raspberry Pi, with the
 116 exception of netbase, which is needed by debootstrap to find
 117 /etc/hosts with the minbase variant.  I really wish there was a way to
 118 set up an Raspberry Pi using only packages in the Debian archive, but
 119 that is not possible as far as I know, because it boots from the GPU
 120 using a non-free binary blob.</p>
 121
 122 <p>The build host need debootstrap, kpartx and qemu-user-static and
 123 probably a few others installed.  I have not checked the complete
 124 build dependency list.</p>
 125
 126 <p>The resulting image will not use the hardware floating point unit
 127 on the Raspberry PI, because the armel architecture in Debian is not
 128 optimized for that use.  So the images created will be a bit slower
 129 than <a href="http://www.raspbian.org/">Raspbian</a> based images.</p>

 143       <div class="date">26th October 2013</div>
 144       <div class="body"><p>De siste måneders eksponering av
 145 <a href="http://www.aftenposten.no/nyheter/uriks/Her-er-Edvard-Snowdens-mest-omtalte-avsloringer-7351734.html">den
 146 totale overvåkningen som foregår i den vestlige verden dokumenterer
 147 hvor sårbare vi er</a>.  Men det slår meg at de som er mest sårbare
 148 for dette, myndighetspersoner på alle nivåer, neppe har innsett at de
 149 selv er de mest interessante personene å lage profiler på, for å kunne
 150 påvirke dem.</p>
 151
 152 <p>For å ta et lite eksempel: Stortingets nettsted,
 153 <a href="http://www.stortinget.no/">www.stortinget.no</a> (og
 154 forsåvidt også
 155 <a href="http://data.stortinget.no/">data.stortinget.no</a>),
 156 inneholder informasjon om det som foregår på Stortinget, og jeg antar
 157 de største brukerne av informasjonen der er representanter og
 158 rådgivere på Stortinget.  Intet overraskende med det.  Det som derimot
 159 er mer skjult er at Stortingets nettsted bruker
 160 <a href="http://en.wikipedia.org/wiki/Google_Analytics">Google
 161 Analytics</a>, hvilket gjør at enhver som besøker nettsidene der også
 162 rapporterer om besøket via Internett-linjer som passerer Sverige,
 163 England og videre til USA.  Det betyr at informasjon om ethvert besøk
 164 på stortingets nettsider kan snappes opp av svensk, britisk og USAs
 165 etterretningsvesen.  De kan dermed holde et øye med hvilke
 166 Stortingssaker stortingsrepresentantene synes er interessante å sjekke
 167 ut, og hvilke sider rådgivere og andre på stortinget synes er
 168 interessant å besøke, når de gjør det og hvilke andre representanter
 169 som sjekker de samme sidene omtrent samtidig.  Stortingets bruk av
 170 Google Analytics gjør det dermed enkelt for utenlands etteretning å
 171 spore representantenes aktivitet og interesse.  Hvis noen av
 172 representantene bruker Google Mail eller noen andre tjenestene som
 173 krever innlogging, så vil det være enda enklere å finne ut nøyaktig
 174 hvilke personer som bruker hvilke nettlesere og dermed knytte
 175 informasjonen opp til enkeltpersoner på Stortinget.</p>
 176
 177 <p>Og jo flere nettsteder som bruker Google Analytics, jo bedre
 178 oversikt over stortingsrepresentantenes lesevaner og interesse blir
 179 tilgjengelig for svensk, britisk og USAs etterretning.  Hva de kan
 180 bruke den informasjonen til overlater jeg til leseren å undres
 181 over.</p>

 195       <div class="date">21st October 2013</div>
 196       <div class="body"><p>The last few days I have been experimenting with
 197 <a href="http://www.open-mesh.org/projects/batman-adv/wiki">the
 198 batman-adv mesh technology</a>.  I want to gain some experience to see
 199 if it will fit <a href="https://wiki.debian.org/FreedomBox">the
 200 Freedombox project</a>, and together with my neighbors try to build a
 201 mesh network around the park where I live.  Batman-adv is a layer 2
 202 mesh system ("ethernet" in other words), where the mesh network appear
 203 as if all the mesh clients are connected to the same switch.</p>
 204
 205 <p>My hardware of choice was the Linksys WRT54GL routers I had lying
 206 around, but I've been unable to get them working with batman-adv.  So
 207 instead, I started playing with a
 208 <a href="http://www.raspberrypi.org/">Raspberry Pi</a>, and tried to
 209 get it working as a mesh node.  My idea is to use it to create a mesh
 210 node which function as a switch port, where everything connected to
 211 the Raspberry Pi ethernet plug is connected (bridged) to the mesh
 212 network.  This allow me to hook a wifi base station like the Linksys
 213 WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
 214 non-mesh clients to hook up to the mesh.  This in turn is useful for
 215 Android phones using <a href="http://servalproject.org/">the Serval
 216 Project</a> voip client, allowing every one around the playground to
 217 phone and message each other for free.  The reason is that Android
 218 phones do not see ad-hoc wifi networks (they are filtered away from
 219 the GUI view), and can not join the mesh without being rooted.  But if
 220 they are connected using a normal wifi base station, they can talk to
 221 every client on the local network.</p>
 222
 223 <p>To get this working, I've created a debian package
 224 <a href="https://github.com/petterreinholdtsen/meshfx-node">meshfx-node</a>
 225 and a script
 226 <a href="https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node">build-rpi-mesh-node</a>
 227 to create the Raspberry Pi boot image.  I'm using Debian Jessie (and
 228 not Raspbian), to get more control over the packages available.
 229 Unfortunately a huge binary blob need to be inserted into the boot
 230 image to get it booting, but I'll ignore that for now.  Also, as
 231 Debian lack support for the CPU features available in the Raspberry
 232 Pi, the system do not use the hardware floating point unit.  I hope
 233 the routing performance isn't affected by the lack of hardware FPU
 234 support.</p>
 235
 236 <p>To create an image, run the following with a sudo enabled user
 237 after inserting the target SD card into the build machine:</p>
 238
 239 <p><pre>
 240 % wget -O build-rpi-mesh-node \
 241     https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
 242 % sudo bash -x ./build-rpi-mesh-node > build.log 2>&1
 243 % dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
 244 %
 245 </pre></p>
 246
 247 <p>Booting with the resulting SD card on a Raspberry PI with a USB
 248 wifi card inserted should give you a mesh node.  At least it does for
 249 me with a the wifi card I am using. The default mesh settings are the
 250 ones used by the Oslo mesh project at Hackeriet, as I mentioned in
 251 <a href="http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html">an
 252 earlier blog post about this mesh testing</a>.</p>
 253
 254 <p>The mesh node was not horribly expensive either.  I bought
 255 everything over the counter in shops nearby.  If I had ordered online
 256 from the lowest bidder, the price should be significantly lower:</p>
 257
 258 <p><table>
 259
 260 <tr><th>Supplier</th><th>Model</th><th>NOK</th></tr>
 261 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi model B</td><td>349.90</td></tr>
 262 <tr><td>Teknikkmagasinet</td><td>Raspberry Pi type B case</td><td>99.90</td></tr>
 263 <tr><td>Lefdal</td><td>Jensen Air:Link 25150</td><td>295.-</td></tr>
 264 <tr><td>Clas Ohlson</td><td>Kingston 16 GB SD card</td><td>199.-</td></tr>
 265 <tr><td>Total cost</td><td></td><td>943.80</td></tr>
 266
 267 </table></p>
 268
 269 <p>Now my mesh network at home consist of one laptop in the basement
 270 connected to my production network, one Raspberry Pi node on the 1th
 271 floor that can be seen by my neighbor across the park, and one
 272 play-node I use to develop the image building script.  And some times
 273 I hook up my work horse laptop to the mesh to test it.  I look forward
 274 to figuring out what kind of latency the batman-adv setup will give,
 275 and how much packet loss we will experience around the park. :)</p>

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

 400
 401 <p>I mentioned OLSR and batman-adv, which are mesh routing protocols.
 402 There are heaps of different protocols, and I am still struggling to
 403 figure out which one would be "best" for some definitions of best, but
 404 given that the community mesh group in Oslo is so small, I believe it
 405 is best to hook up with the existing one instead of trying to create a
 406 completely different setup, and thus I have decided to focus on
 407 batman-adv for now.  It sure help me to  know that the very cool
 408 <a href="http://www.servalproject.org/">Serval project in Australia</a>
 409 is using batman-adv as their meshing technology when it create a self
 410 organizing and self healing telephony system for disaster areas and
 411 less industrialized communities.  Check out this cool video presenting
 412 that project (from
 413 <a href="https://www.youtube.com/watch?v=30qNfzJCQOA">youtube</a>):</p>

 416
 417 <p>According to the wikipedia page on
 418 <a href="http://en.wikipedia.org/wiki/Wireless_mesh_network">Wireless
 419 mesh network</a> there are around 70 competing schemes for routing
 420 packets across mesh networks, and OLSR, B.A.T.M.A.N. and
 421 B.A.T.M.A.N. advanced are protocols used by several free software
 422 based community mesh networks.</p>
 423
 424 <p>The batman-adv protocol is a bit special, as it provide layer 2
 425 (as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same
 426 network.  One way to think about it is that it provide a mesh based
 427 vlan you can bridge to or handle like any other vlan connected to your
 428 computer.  The required drivers are already in the Linux kernel at
 429 least since Debian Wheezy, and it is fairly easy to set up.  A
 430 <a href="http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide">good
 431 introduction</a> is available from the Open Mesh project.  These are
 432 the key settings needed to join the Oslo meshfx network:</p>
 433
 434 <p><table>
 435 <tr><th>Setting</th><th>Value</th></tr>
 436 <tr><td>Protocol / kernel module</td><td>batman-adv</td></tr>
 437 <tr><td>ESSID</td><td>meshfx@hackeriet</td></tr>
 438 <td>Channel / Frequency</td><td>11 / 2462</td></tr>
 439 <td>Cell ID</td><td>02:BA:00:00:00:01</td>
 440 </table></p>
 441
 442 <p>The reason for setting ad-hoc wifi Cell ID is to work around bugs
 443 in firmware used in wifi card and wifi drivers.  (See a nice post from
 444 VillageTelco about
 445 "<a href="http://tiebing.blogspot.no/2009/12/ad-hoc-cell-splitting-re-post-original.html">Information
 446 about cell-id splitting, stuck beacons, and failed IBSS merges!</a>
 447 for details.)  When these settings are activated and you have some
 448 other mesh node nearby, your computer will be connected to the mesh
 449 network and can communicate with any mesh node that is connected to
 450 any of the nodes in your network of nodes. :)</p>
 451
 452 <p>My initial plan was to reuse my old Linksys WRT54GL as a mesh node,
 453 but that seem to be very hard, as I have not been able to locate a
 454 firmware supporting batman-adv.  If anyone know how to use that old
 455 wifi access point with batman-adv these days, please let me know.</p>
 456
 457 <p>If you find this project interesting and want to join, please join
 458 us on IRC, either channel
 459 <a href="irc://irc.freenode.net/#oslohackerspace">#oslohackerspace</a>
 460 or <a href="irc://irc.freenode.net/#nuug">#nuug</a> on
 461 irc.freenode.net.</p>
 462
 463 <p>While investigating mesh networks in Oslo, I came across an old
 464 research paper from the university of Stavanger and Telenor Research
 465 and Innovation called
 466 <a href="http://folk.uio.no/paalee/publications/netrel-egeland-iswcs-2008.pdf">The
 467 reliability of wireless backhaul mesh networks</a> and elsewhere
 468 learned that Telenor have been experimenting with mesh networks at
 469 Grünerløkka in Oslo.  So mesh networks are also interesting for
 470 commercial companies, even though Telenor discovered that it was hard
 471 to figure out a good business plan for mesh networking and as far as I
 472 know have closed down the experiment.  Perhaps Telenor or others would
 473 be interested in a cooperation?</p>
 474
 475 <p><strong>Update 2013-10-12</strong>: I was just
 476 <a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2013-October/005900.html">told
 477 by the Serval project developers</a> that they no longer use
 478 batman-adv (but are compatible with it), but their own crypto based
 479 mesh system.</p>

 494       <div class="body"><p>The other day I was pleased and surprised to discover that Marcelo
 495 Salvador had published a
 496 <a href="https://www.youtube.com/watch?v=w-GgpdqgLFc">video on
 497 Youtube</a> showing how to install the standalone Debian Edu /
 498 Skolelinux profile.  This is the profile intended for use at home or
 499 on laptops that should not be integrated into the provided network
 500 services (no central home directory, no Kerberos / LDAP directory etc,
 501 in other word a single user machine).  The result is 11 minutes long,
 502 and show some user applications (seem to be rather randomly picked).
 503 Missed a few of my favorites like celestia, planets and chromium
 504 showing the <a href="http://www.zygotebody.com/">Zygote Body 3D model
 505 of the human body</a>, but I guess he did not know about those or find
 506 other programs more interesting. :) And the video do not show the
 507 advantages I believe is one of the most valuable featuers in Debian
 508 Edu, its central school server making it possible to run hundreds of
 509 computers without hard drives by installing one central
 510 <a href="http://www.ltsp.org/">LTSP server</a>.</p>

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

 698 <p>About Debian Edu and Skolelinux</p>
 699
 700 <p>Debian Edu, also known as Skolelinux, is a Linux distribution based
 701 on Debian providing an out-of-the box environment of a completely
 702 configured school network. Immediately after installation a school
 703 server running all services needed for a school network is set up just
 704 waiting for users and machines being added via GOsa², a comfortable
 705 Web-UI. A netbooting environment is prepared using PXE, so after
 706 initial installation of the main server from CD or USB stick all other
 707 machines can be installed via the network. The provided school server
 708 provides LDAP database and Kerberos authentication service,
 709 centralized home directories, DHCP server, web proxy and many other
 710 services.  The desktop contains more than 60 educational software
 711 packages and more are available from the Debian archive, and schools
 712 can choose between KDE, Gnome, LXDE and Xfce desktop environment.</p>
 713
 714 <p>This is the seventh test release based on Debian Wheezy. Basically
 715 this is an updated and slightly improved version compared to the
 716 Squeeze release.</p>
 717
 718 <p>Notes for upgrades from Alpha Prereleases</p>
 719
 720 <p>Alpha based installations should reinstall or downgrade the
 721 versions of gosa and libpam-mklocaluser to the ones used in this beta
 722 release. Both alpha and beta0 based installations should reinstall or
 723 deal with gosa.conf manually; there are two options: (1) Keep
 724 gosa.conf and edit this file as outlined on the mailing list. (2)
 725 Accept the new version of gosa.conf and replace both contained admin
 726 password placeholders with the password hashes found in the old one
 727 (backup copy!). In both cases all users need to change their password
 728 to make sure a password is set for CIFS access to their home
 729 directory.</p>
 730
 731
 732 <p>cheers,
 733 <br>        Holger</p>
