  24       <div class="date">18th January 2013</div>
  25       <div class="body"><p>Some times I try to figure out which Iceweasel browser plugin to
  26 install to get support for a given MIME type.  Thanks to
  27 <a href="https://wiki.ubuntu.com/MozillaTeam/Plugins">specifications
  28 done by Ubuntu</a> and Mozilla, it is possible to do this in Debian.
  29 Unfortunately, not very many packages provide the needed meta
  30 information, Anyway, here is a small script to look up all browser
  31 plugin packages announcing ther MIME support using this specification:</p>
  32
  33 <pre>
  34 #!/usr/bin/python
  35 import sys
  36 import apt
  37 def pkgs_handling_mimetype(mimetype):
  38     cache = apt.Cache()
  39     cache.open(None)
  40     thepkgs = []
  41     for pkg in cache:
  42         version = pkg.candidate
  43         if version is None:
  44             version = pkg.installed
  45         if version is None:
  46             continue
  47         record = version.record
  48         if not record.has_key('Npp-MimeType'):
  49             continue
  50         mime_types = record['Npp-MimeType'].split(',')
  51         for t in mime_types:
  52             t = t.rstrip().strip()
  53             if t == mimetype:
  54                 thepkgs.append(pkg.name)
  55     return thepkgs
  56 mimetype = "audio/ogg"
  57 if 1 < len(sys.argv):
  58     mimetype = sys.argv[1]
  59 print "Browser plugin packages supporting %s:" % mimetype
  60 for pkg in pkgs_handling_mimetype(mimetype):
  61     print "  %s" %pkg
  62 </pre>
  63
  64 <p>It can be used like this to look up a given MIME type:</p>
  65
  66 <pre>
  67 % ./apt-find-browserplug-for-mimetype
  68 Browser plugin packages supporting audio/ogg:
  69   gecko-mediaplayer
  70 % ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
  71 Browser plugin packages supporting application/x-shockwave-flash:
  72   browser-plugin-gnash
  73 %
  74 </pre>
  75
  76 <p>In Ubuntu this mechanism is combined with support in the browser
  77 itself to query for plugins and propose to install the needed
  78 packages.  It would be great if Debian supported such feature too.  Is
  79 anyone working on adding it?</p>

  94       <div class="body"><p>The <a href="http://wiki.debian.org/AppStreamDebianProposal">DEP-11
  95 proposal to add AppStream information to the Debian archive</a>, is a
  96 proposal to make it possible for a Desktop application to propose to
  97 the user some package to install to gain support for a given MIME
  98 type, font, library etc. that is currently missing.  With such
  99 mechanism in place, it would be possible for the desktop to
 100 automatically propose and install leocad if some LDraw file is
 101 downloaded by the browser.</p>
 102
 103 <p>To get some idea about the current content of the archive, I decided
 104 to write a simple program to extract all .desktop files from the
 105 Debian archive and look up the claimed MIME support there.  The result
 106 can be found on the
 107 <a href="http://ftp.skolelinux.org/pub/AppStreamTest">Skolelinux FTP
 108 site</a>.  Using the collected information, it become possible to
 109 answer the question in the title.  Here are the 20 most supported MIME
 110 types in Debian stable (Squeeze), testing (Wheezy) and unstable (Sid).
 111 The complete list is available from the link above.</p>

 194 <p>I am told that PackageKit can provide an API to access the kind of
 195 information mentioned in DEP-11.  I have not yet had time to look at
 196 it, but hope the PackageKit people in Debian are on top of these
 197 issues.</p>

 214       <div class="date">15th January 2013</div>
 215       <div class="body"><p>Yesterday, I wrote about the
 216 <a href="http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html">modalias
 217 values provided by the Linux kernel</a> following my hope for
 218 <a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">better
 219 dongle support in Debian</a>.  Using this knowledge, I have tested how
 220 modalias values attached to package names can be used to map packages
 221 to hardware.  This allow the system to look up and suggest relevant
 222 packages when I plug in some new hardware into my machine, and replace
 223 discover and discover-data as the database used to map hardware to
 224 packages.</p>
 225
 226 <p>I create a modaliases file with entries like the following,
 227 containing package name, kernel module name (if relevant, otherwise
 228 the package name) and globs matching the relevant hardware
 229 modalias.</p>
 230
 231 <p><blockquote>
 232 Package: package-name
 233 <br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)</p>
 234 </blockquote></p>
 235
 236 <p>It is fairly trivial to write code to find the relevant packages
 237 for a given modalias value using this file.</p>
 238
 239 <p>An entry like this would suggest the video and picture application
 240 cheese for many USB web cameras (interface bus class 0E01):</p>
 241
 242 <p><blockquote>
 243 Package: cheese
 244 <br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)</p>
 245 </blockquote></p>
 246
 247 <p>An entry like this would suggest the pcmciautils package when a
 248 CardBus bridge (bus class 0607) PCI device is present:</p>
 249
 250 <p><blockquote>
 251 Package: pcmciautils
 252 <br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
 253 </blockquote></p>
 254
 255 <p>An entry like this would suggest the package colorhug-client when
 256 plugging in a ColorHug with USB IDs 04D8:F8DA:</p>
 257
 258 <p><blockquote>
 259 Package: colorhug-client
 260 <br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)</p>
 261 </blockquote></p>
 262
 263 <p>I believe the format is compatible with the format of the Packages
 264 file in the Debian archive.  Ubuntu already uses their Packages file
 265 to store their mappings from packages to hardware.</p>
 266
 267 <p>By adding a XB-Modaliases: header in debian/control, any .deb can
 268 announce the hardware it support in a way my prototype understand.
 269 This allow those publishing packages in an APT source outside the
 270 Debian archive as well as those backporting packages to make sure the
 271 hardware mapping are included in the package meta information.  I've
 272 tested such header in the pymissile package, and its modalias mapping
 273 is working as it should with my prototype.  It even made it to Ubuntu
 274 Raring.</p>
 275
 276 <p>To test if it was possible to look up supported hardware using only
 277 the shell tools available in the Debian installer, I wrote a shell
 278 implementation of the lookup code.  The idea is to create files for
 279 each modalias and let the shell do the matching.  Please check out and
 280 try the
 281 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup</a>
 282 shell script.  It run without any extra dependencies and fetch the
 283 hardware mappings from the Debian archive and the subversion
 284 repository where I currently work on my prototype.</p>
 285
 286 <p>When I use it on a machine with a yubikey inserted, it suggest to
 287 install yubikey-personalization:</p>
 288
 289 <p><blockquote>
 290 % ./hw-support-lookup
 291 <br>yubikey-personalization
 292 <br>%
 293 </blockquote></p>
 294
 295 <p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
 296 propose to install the pcmciautils package:</p>
 297
 298 <p><blockquote>
 299 % ./hw-support-lookup
 300 <br>pcmciautils
 301 <br>%
 302 </blockquote></p>
 303
 304 <p>If you know of any hardware-package mapping that should be added to
 305 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
 306 database</a>, please tell me about it.</p>
 307
 308 <p>It could be possible to generate several of the mappings between
 309 packages and hardware.  One source would be to look at packages with
 310 kernel modules, ie packages with *.ko files in /lib/modules/, and
 311 extract their modalias information.  Another would be to look at
 312 packages with udev rules, ie packages with files in
 313 /lib/udev/rules.d/, and extract their vendor/model information to
 314 generate a modalias matching rule.  I have not tested any of these to
 315 see if it work.</p>
 316
 317 <p>If you want to help implementing a system to let us propose what
 318 packages to install when new hardware is plugged into a Debian
 319 machine, please send me an email or talk to me on
 320 <a href="irc://irc.debian.org/%23debian-devel">#debian-devel</a>.</p>

 335       <div class="body"><p>While looking into how to look up Debian packages based on hardware
 336 information, to find the packages that support a given piece of

 339 in
 340 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 341 Debian Edu subversion repository</a>:
 342
 343 <p><strong>Modalias decoded</strong></p>
 344
 345 <p>This document try to explain what the different types of modalias
 346 values stands for.  It is in part based on information from
 347 &lt;URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> &gt;,
 348 &lt;URL: <a href="http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device">http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device</a> &gt;,

 351
 352 <p>The modalias entries for a given Linux machine can be found using
 353 this shell script:</p>
 354
 355 <pre>
 356 find /sys -name modalias -print0 | xargs -0 cat | sort -u
 357 </pre>
 358
 359 <p>The supported modalias globs for a given kernel module can be found
 360 using modinfo:</p>
 361
 362 <pre>
 363 % /sbin/modinfo psmouse | grep alias:
 364 alias:          serio:ty05pr*id*ex*
 365 alias:          serio:ty01pr*id*ex*
 366 %
 367 </pre>
 368
 369 <p><strong>PCI subtype</strong></p>
 370
 371 <p>A typical PCI entry can look like this.  This is an Intel Host
 372 Bridge memory controller:</p>
 373
 374 <p><blockquote>
 375 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
 376 </blockquote></p>
 377
 378 <p>This represent these values:</p>
 379
 380 <pre>
 381  v   00008086  (vendor)
 382  d   00002770  (device)
 383  sv  00001028  (subvendor)
 384  sd  000001AD  (subdevice)
 385  bc  06        (bus class)
 386  sc  00        (bus subclass)
 387  i   00        (interface)
 388 </pre>
 389
 390 <p>The vendor/device values are the same values outputted from 'lspci
 391 -n' as 8086:2770.  The bus class/subclass is also shown by lspci as
 392 0600.  The 0600 class is a host bridge.  Other useful bus values are
 393 0300 (VGA compatible card) and 0200 (Ethernet controller).</p>
 394
 395 <p>Not sure how to figure out the interface value, nor what it
 396 means.</p>
 397
 398 <p><strong>USB subtype</strong></p>
 399
 400 <p>Some typical USB entries can look like this.  This is an internal
 401 USB hub in a laptop:</p>
 402
 403 <p><blockquote>
 404 usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
 405 </blockquote></p>
 406
 407 <p>Here is the values included in this alias:</p>
 408
 409 <pre>
 410  v    1D6B  (device vendor)
 411  p    0001  (device product)
 412  d    0206  (bcddevice)
 413  dc     09  (device class)
 414  dsc    00  (device subclass)
 415  dp     00  (device protocol)
 416  ic     09  (interface class)
 417  isc    00  (interface subclass)
 418  ip     00  (interface protocol)
 419 </pre>
 420
 421 <p>The 0900 device class/subclass means hub.  Some times the relevant
 422 class is in the interface class section.  For a simple USB web camera,
 423 these alias entries show up:</p>
 424
 425 <p><blockquote>
 426 usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
 427 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
 428 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
 429 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
 430 </blockquote></p>
 431
 432 <p>Interface class 0E01 is video control, 0E02 is video streaming (aka
 433 camera), 0101 is audio control device and 0102 is audio streaming (aka
 434 microphone).  Thus this is a camera with microphone included.</p>
 435
 436 <p><strong>ACPI subtype</strong></p>
 437
 438 <p>The ACPI type is used for several non-PCI/USB stuff.  This is an IR
 439 receiver in a Thinkpad X40:</p>
 440
 441 <p><blockquote>
 442 acpi:IBM0071:PNP0511:
 443 </blockquote></p>
 444
 445 <p>The values between the colons are IDs.</p>
 446

 507 <p>The chassis type values are not always accurately set in the DMI
 508 table.  For example my home server is a tower, but the DMI modalias
 509 claim it is a desktop.</p>
 510
 511 <p><strong>SerIO subtype</strong></p>
 512
 513 <p>This type is used for PS/2 mouse plugs.  One example is from my
 514 test machine:</p>
 515
 516 <p><blockquote>

 528
 529 <p>This type is supported by the psmouse driver.  I am not sure what
 530 the valid values are.</p>
 531
 532 <p><strong>Other subtypes</strong></p>
 533
 534 <p>There are heaps of other modalias subtypes according to
 535 file2alias.c.  There is the rest of the list from that source: amba,
 536 ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
 537 mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
 538 vmbus, x86cpu and zorro.  I did not spend time documenting all of
 539 these, as they do not seem relevant for my intended use with mapping
 540 hardware to packages when new stuff is inserted during run time.</p>
 541
 542 <p><strong>Looking up kernel modules using modalias values</strong></p>
 543
 544 <p>To check which kernel modules provide support for a given modalias,
 545 one can use the following shell script:</p>
 546
 547 <pre>
 548   for id in $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \
 549     echo "$id" ; \
 550     /sbin/modprobe --show-depends "$id"|sed 's/^/  /' ; \
 551   done
 552 </pre>
 553
 554 <p>The output can look like this (only the first few entries as the
 555 list is very long on my test machine):</p>

 596       <div class="body"><p>As part of my investigation on how to improve the support in Debian
 597 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
 598 Launcher and updated the Debian package
 599 <a href="http://packages.qa.debian.org/pymissile">pymissile</a> to make
 600 sure udev will fix the device permissions when it is plugged in.  I
 601 also added a "Modaliases" header to test it in the Debian archive and
 602 hopefully make the package be proposed by jockey in Ubuntu when a user
 603 plug in his rocket launcher.  In the process I moved the source to a
 604 git repository under collab-maint, to make it easier for any DD to
 605 contribute.  <a href="http://code.google.com/p/pymissile/">Upstream</a>
 606 is not very active, but the software still work for me even after five
 607 years of relative silence.  The new git repository is not listed in
 608 the uploaded package yet, because I want to test the other changes a
 609 bit more before I upload the new version.  If you want to check out
 610 the new version with a .desktop file included, visit the
 611 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/pymissile.git">gitweb

 627       <div class="date"> 9th January 2013</div>
 628       <div class="body"><p>One thing that annoys me with Debian and Linux distributions in
 629 general, is that there is a great package management system with the
 630 ability to automatically install software packages by downloading them
 631 from the distribution mirrors, but no way to get it to automatically
 632 install the packages I need to use the hardware I plug into my
 633 machine.  Even if the package to use it is easily available from the
 634 Linux distribution.  When I plug in a LEGO Mindstorms NXT, it could
 635 suggest to automatically install the python-nxt, nbc and t2n packages
 636 I need to talk to it.  When I plug in a Yubikey, it could propose the
 637 yubikey-personalization package.  The information required to do this
 638 is available, but no-one have pulled all the pieces together.</p>
 639
 640 <p>Some years ago, I proposed to
 641 <a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
 642 the discover subsystem to implement this</a>.  The idea is fairly
 643 simple:
 644
 645 <ul>
 646
 647 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
 648   starting when a user log in.</li>
 649
 650 <li>Set this program up to listen for kernel events emitted when new
 651   hardware is inserted into the computer.</li>
 652
 653 <li>When new hardware is inserted, look up the hardware ID in a
 654   database mapping to packages, and take note of any non-installed
 655   packages.</li>
 656
 657 <li>Show a message to the user proposing to install the discovered
 658   package, and make it easy to install it.</li>
 659
 660 </ul>
 661
 662 <p>I am not sure what the best way to implement this is, but my
 663 initial idea was to use dbus events to discover new hardware, the
 664 discover database to find packages and
 665 <a href="http://www.packagekit.org/">PackageKit</a> to install
 666 packages.</p>
 667
 668 <p>Yesterday, I found time to try to implement this idea, and the
 669 draft package is now checked into
 670 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 671 Debian Edu subversion repository</a>.  In the process, I updated the
 672 <a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
 673 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
 674 the relevant packages in Debian, and uploaded a new version
 675 2.2013.01.09 to unstable.  I also discovered that the current
 676 <a href="http://packages.qa.debian.org/d/discover.html">discover</a>
 677 package in Debian no longer discovered any USB devices, because
 678 /proc/bus/usb/devices is no longer present.  I ported it to use
 679 libusb as a fall back option to get it working.  The fixed package
 680 version 2.1.2-6 is now in experimental (didn't upload it to unstable
 681 because of the freeze).</p>
 682
 683 <p>With this prototype in place, I can insert my Yubikey, and get this
 684 desktop notification to show up (only once, the first time it is
 685 inserted):</p>
 686
 687 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
 688
 689 <p>For this prototype to be really useful, some way to automatically
 690 install the proposed packages by pressing the "Please install
 691 program(s)" button should to be implemented.</p>
 692
 693 <p>If this idea seem useful to you, and you want to help make it
 694 happen, please help me update the discover-data database with mappings
 695 from hardware to Debian packages.  Check if 'discover-pkginstall -l'
 696 list the package you would like to have installed when a given
 697 hardware device is inserted into your computer, and report bugs using
 698 reportbug if it isn't.  Or, if you know of a better way to provide
 699 such mapping, please let me know.</p>
 700
 701 <p>This prototype need more work, and there are several questions that
 702 should be considered before it is ready for production use.  Is dbus
 703 the correct way to detect new hardware?  At the moment I look for HAL
 704 dbus events on the system bus, because that is the events I could see
 705 on my Debian Squeeze KDE desktop.  Are there better events to use?
 706 How should the user be notified?  Is the desktop notification
 707 mechanism the best option, or should the background daemon raise a
 708 popup instead?  How should packages be installed?  When should they
 709 not be installed?</p>
 710
 711 <p>If you want to help getting such feature implemented in Debian,
 712 please send me an email. :)</p>

 859       <div class="date">28th December 2012</div>
 860       <div class="body"><p>I was happy to discover a few days ago that the
 861 <a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a>
 862 project also this year received a Christmas present from Another
 863 Agency in Trondheim.  NOK 1000,- showed up on our donation account
 864 December 24th.  I want to express our thanks for this very welcome
 865 present.  As the Debian Edu / Skolelinux project is very short on
 866 funding these days, and thus lack the money to do regular developer
 867 gatherings, this donation was most welcome.  One developer gathering
 868 cost around NOK 15&nbsp;000,-, so we need quite a lot more to keep the
 869 development pace we want.  Thus, I hope their example this year is
 870 followed by many others. :)</p>
 871
 872 <p>The public list of donors can be found on
 873 <a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">the
 874 donation page</a> for the project, which also contain instructions if
 875 you want to donate to the project.</p>

 889       <div class="date">25th December 2012</div>
 890       <div class="body"><p>Let me start by wishing you all marry Christmas and a happy new
 891 year!  I hope next year will prove to be a good year.</p>
 892
 893 <p><a href="http://www.bitcoin.org/">Bitcoin</a>, the digital
 894 decentralised "currency" that allow people to transfer bitcoins
 895 between each other with minimal overhead, is a very interesting
 896 experiment.  And as I wrote a few days ago, the bitcoin situation in
 897 <a href="http://www.debian.org/">Debian</a> is about to improve a bit.
 898 The <a href="http://packages.qa.debian.org/bitcoin">new debian source
 899 package</a> (version 0.7.2-2) was uploaded yesterday, and is waiting
 900 in <a href="http://ftp-master.debian.org/new.html">the NEW queue</A>
 901 for one of the ftpmasters to approve the new bitcoin-qt package
 902 name.</p>
 903
 904 <p>And thanks to the great work of Jonas and the rest of the bitcoin
 905 team in Debian, you can easily test the package in Debian Squeeze
 906 using the following steps to get a set of working packages:</p>
 907
 908 <blockquote><pre>
 909 git clone git://git.debian.org/git/collab-maint/bitcoin
 910 cd bitcoin
 911 DEB_MAINTAINER_MODE=1 DEB_BUILD_OPTIONS=noupnp fakeroot debian/rules clean
 912 DEB_BUILD_OPTIONS=noupnp git-buildpackage --git-ignore-new
 913 </pre></blockquote>
 914
 915 <p>You might have to install some build dependencies as well.  The
 916 list of commands should give you two packages, bitcoind and
 917 bitcoin-qt, ready for use in a Squeeze environment.  Note that the
 918 client will download the complete set of bitcoin "blocks", which need
 919 around 5.6 GiB of data on my machine at the moment.  Make sure your
 920 ~/.bitcoin/ directory have lots of spare room if you want to download
 921 all the blocks.  The client will warn if the disk is getting full, so
 922 there is not really a problem if you got too little room, but you will
 923 not be able to get all the features out of the client.</p>
 924
 925 <p>As usual, if you use bitcoin and want to show your support of my
 926 activities, please send Bitcoin donations to my address
