  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>
  80
  81 <p><strong>Update 2013-01-18 14:20</strong>: The Debian BTS
  82 request for icweasel support for this feature is
  83 <a href="http://bugs.debian.org/484010">#484010</a> from 2008 (and
  84 <a href="http://bugs.debian.org/698426">#698426</a> from today).  Lack
  85 of manpower and wish for a different design is the reason thus feature
  86 is not yet in iceweasel from Debian.</p>

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

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

 221       <div class="date">15th January 2013</div>
 222       <div class="body"><p>Yesterday, I wrote about the
 223 <a href="http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html">modalias
 224 values provided by the Linux kernel</a> following my hope for
 225 <a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">better
 226 dongle support in Debian</a>.  Using this knowledge, I have tested how
 227 modalias values attached to package names can be used to map packages
 228 to hardware.  This allow the system to look up and suggest relevant
 229 packages when I plug in some new hardware into my machine, and replace
 230 discover and discover-data as the database used to map hardware to
 231 packages.</p>
 232
 233 <p>I create a modaliases file with entries like the following,
 234 containing package name, kernel module name (if relevant, otherwise
 235 the package name) and globs matching the relevant hardware
 236 modalias.</p>
 237
 238 <p><blockquote>
 239 Package: package-name
 240 <br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)</p>
 241 </blockquote></p>
 242
 243 <p>It is fairly trivial to write code to find the relevant packages
 244 for a given modalias value using this file.</p>
 245
 246 <p>An entry like this would suggest the video and picture application
 247 cheese for many USB web cameras (interface bus class 0E01):</p>
 248
 249 <p><blockquote>
 250 Package: cheese
 251 <br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)</p>
 252 </blockquote></p>
 253
 254 <p>An entry like this would suggest the pcmciautils package when a
 255 CardBus bridge (bus class 0607) PCI device is present:</p>
 256
 257 <p><blockquote>
 258 Package: pcmciautils
 259 <br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
 260 </blockquote></p>
 261
 262 <p>An entry like this would suggest the package colorhug-client when
 263 plugging in a ColorHug with USB IDs 04D8:F8DA:</p>
 264
 265 <p><blockquote>
 266 Package: colorhug-client
 267 <br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)</p>
 268 </blockquote></p>
 269
 270 <p>I believe the format is compatible with the format of the Packages
 271 file in the Debian archive.  Ubuntu already uses their Packages file
 272 to store their mappings from packages to hardware.</p>
 273
 274 <p>By adding a XB-Modaliases: header in debian/control, any .deb can
 275 announce the hardware it support in a way my prototype understand.
 276 This allow those publishing packages in an APT source outside the
 277 Debian archive as well as those backporting packages to make sure the
 278 hardware mapping are included in the package meta information.  I've
 279 tested such header in the pymissile package, and its modalias mapping
 280 is working as it should with my prototype.  It even made it to Ubuntu
 281 Raring.</p>
 282
 283 <p>To test if it was possible to look up supported hardware using only
 284 the shell tools available in the Debian installer, I wrote a shell
 285 implementation of the lookup code.  The idea is to create files for
 286 each modalias and let the shell do the matching.  Please check out and
 287 try the
 288 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup</a>
 289 shell script.  It run without any extra dependencies and fetch the
 290 hardware mappings from the Debian archive and the subversion
 291 repository where I currently work on my prototype.</p>
 292
 293 <p>When I use it on a machine with a yubikey inserted, it suggest to
 294 install yubikey-personalization:</p>
 295
 296 <p><blockquote>
 297 % ./hw-support-lookup
 298 <br>yubikey-personalization
 299 <br>%
 300 </blockquote></p>
 301
 302 <p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
 303 propose to install the pcmciautils package:</p>
 304
 305 <p><blockquote>
 306 % ./hw-support-lookup
 307 <br>pcmciautils
 308 <br>%
 309 </blockquote></p>
 310
 311 <p>If you know of any hardware-package mapping that should be added to
 312 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
 313 database</a>, please tell me about it.</p>
 314
 315 <p>It could be possible to generate several of the mappings between
 316 packages and hardware.  One source would be to look at packages with
 317 kernel modules, ie packages with *.ko files in /lib/modules/, and
 318 extract their modalias information.  Another would be to look at
 319 packages with udev rules, ie packages with files in
 320 /lib/udev/rules.d/, and extract their vendor/model information to
 321 generate a modalias matching rule.  I have not tested any of these to
 322 see if it work.</p>
 323
 324 <p>If you want to help implementing a system to let us propose what
 325 packages to install when new hardware is plugged into a Debian
 326 machine, please send me an email or talk to me on
 327 <a href="irc://irc.debian.org/%23debian-devel">#debian-devel</a>.</p>

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

 350 <p><strong>Modalias decoded</strong></p>
 351
 352 <p>This document try to explain what the different types of modalias
 353 values stands for.  It is in part based on information from
 354 &lt;URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> &gt;,
 355 &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;,

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

 443 <p><strong>ACPI subtype</strong></p>

 514 <p>The chassis type values are not always accurately set in the DMI

 516 claim it is a desktop.</p>
 517
 518 <p><strong>SerIO subtype</strong></p>
 519
 520 <p>This type is used for PS/2 mouse plugs.  One example is from my
 521 test machine:</p>
 522
 523 <p><blockquote>

 535
 536 <p>This type is supported by the psmouse driver.  I am not sure what
 537 the valid values are.</p>
 538
 539 <p><strong>Other subtypes</strong></p>
 540
 541 <p>There are heaps of other modalias subtypes according to
 542 file2alias.c.  There is the rest of the list from that source: amba,
 543 ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
 544 mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
 545 vmbus, x86cpu and zorro.  I did not spend time documenting all of
 546 these, as they do not seem relevant for my intended use with mapping
 547 hardware to packages when new stuff is inserted during run time.</p>
 548
 549 <p><strong>Looking up kernel modules using modalias values</strong></p>
 550
 551 <p>To check which kernel modules provide support for a given modalias,
 552 one can use the following shell script:</p>
 553
 554 <pre>
 555   for id in $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \
 556     echo "$id" ; \
 557     /sbin/modprobe --show-depends "$id"|sed 's/^/  /' ; \
 558   done
 559 </pre>
 560
 561 <p>The output can look like this (only the first few entries as the
 562 list is very long on my test machine):</p>

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

 634       <div class="date"> 9th January 2013</div>
 635       <div class="body"><p>One thing that annoys me with Debian and Linux distributions in
 636 general, is that there is a great package management system with the
 637 ability to automatically install software packages by downloading them
 638 from the distribution mirrors, but no way to get it to automatically
 639 install the packages I need to use the hardware I plug into my
 640 machine.  Even if the package to use it is easily available from the
 641 Linux distribution.  When I plug in a LEGO Mindstorms NXT, it could
 642 suggest to automatically install the python-nxt, nbc and t2n packages
 643 I need to talk to it.  When I plug in a Yubikey, it could propose the
 644 yubikey-personalization package.  The information required to do this
 645 is available, but no-one have pulled all the pieces together.</p>
 646
 647 <p>Some years ago, I proposed to
 648 <a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
 649 the discover subsystem to implement this</a>.  The idea is fairly
 650 simple:
 651
 652 <ul>
 653
 654 <li>Add a desktop entry in /usr/share/autostart/ pointing to a program
 655   starting when a user log in.</li>
 656
 657 <li>Set this program up to listen for kernel events emitted when new
 658   hardware is inserted into the computer.</li>
 659
 660 <li>When new hardware is inserted, look up the hardware ID in a
 661   database mapping to packages, and take note of any non-installed
 662   packages.</li>
 663
 664 <li>Show a message to the user proposing to install the discovered
 665   package, and make it easy to install it.</li>
 666
 667 </ul>
 668
 669 <p>I am not sure what the best way to implement this is, but my
 670 initial idea was to use dbus events to discover new hardware, the
 671 discover database to find packages and
 672 <a href="http://www.packagekit.org/">PackageKit</a> to install
 673 packages.</p>
 674
 675 <p>Yesterday, I found time to try to implement this idea, and the
 676 draft package is now checked into
 677 <a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
 678 Debian Edu subversion repository</a>.  In the process, I updated the
 679 <a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
 680 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
 681 the relevant packages in Debian, and uploaded a new version
 682 2.2013.01.09 to unstable.  I also discovered that the current
 683 <a href="http://packages.qa.debian.org/d/discover.html">discover</a>
 684 package in Debian no longer discovered any USB devices, because
 685 /proc/bus/usb/devices is no longer present.  I ported it to use
 686 libusb as a fall back option to get it working.  The fixed package
 687 version 2.1.2-6 is now in experimental (didn't upload it to unstable
 688 because of the freeze).</p>
 689
 690 <p>With this prototype in place, I can insert my Yubikey, and get this
 691 desktop notification to show up (only once, the first time it is
 692 inserted):</p>
 693
 694 <p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
 695
 696 <p>For this prototype to be really useful, some way to automatically
 697 install the proposed packages by pressing the "Please install
 698 program(s)" button should to be implemented.</p>
 699
 700 <p>If this idea seem useful to you, and you want to help make it
 701 happen, please help me update the discover-data database with mappings
 702 from hardware to Debian packages.  Check if 'discover-pkginstall -l'
 703 list the package you would like to have installed when a given
 704 hardware device is inserted into your computer, and report bugs using
 705 reportbug if it isn't.  Or, if you know of a better way to provide
 706 such mapping, please let me know.</p>
 707
 708 <p>This prototype need more work, and there are several questions that
 709 should be considered before it is ready for production use.  Is dbus
 710 the correct way to detect new hardware?  At the moment I look for HAL
 711 dbus events on the system bus, because that is the events I could see
 712 on my Debian Squeeze KDE desktop.  Are there better events to use?
 713 How should the user be notified?  Is the desktop notification
 714 mechanism the best option, or should the background daemon raise a
 715 popup instead?  How should packages be installed?  When should they
 716 not be installed?</p>
 717
 718 <p>If you want to help getting such feature implemented in Debian,
 719 please send me an email. :)</p>

 866       <div class="date">28th December 2012</div>
 867       <div class="body"><p>I was happy to discover a few days ago that the
 868 <a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a>
 869 project also this year received a Christmas present from Another
 870 Agency in Trondheim.  NOK 1000,- showed up on our donation account
 871 December 24th.  I want to express our thanks for this very welcome
 872 present.  As the Debian Edu / Skolelinux project is very short on
 873 funding these days, and thus lack the money to do regular developer
 874 gatherings, this donation was most welcome.  One developer gathering
 875 cost around NOK 15&nbsp;000,-, so we need quite a lot more to keep the
 876 development pace we want.  Thus, I hope their example this year is
 877 followed by many others. :)</p>
 878
 879 <p>The public list of donors can be found on
 880 <a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">the
 881 donation page</a> for the project, which also contain instructions if
 882 you want to donate to the project.</p>

 896       <div class="date">25th December 2012</div>
 897       <div class="body"><p>Let me start by wishing you all marry Christmas and a happy new
 898 year!  I hope next year will prove to be a good year.</p>

 900 <p><a href="http://www.bitcoin.org/">Bitcoin</a>, the digital
 901 decentralised "currency" that allow people to transfer bitcoins
 902 between each other with minimal overhead, is a very interesting
 903 experiment.  And as I wrote a few days ago, the bitcoin situation in
 904 <a href="http://www.debian.org/">Debian</a> is about to improve a bit.
 905 The <a href="http://packages.qa.debian.org/bitcoin">new debian source
 906 package</a> (version 0.7.2-2) was uploaded yesterday, and is waiting
 907 in <a href="http://ftp-master.debian.org/new.html">the NEW queue</A>
 908 for one of the ftpmasters to approve the new bitcoin-qt package
 909 name.</p>
 910
 911 <p>And thanks to the great work of Jonas and the rest of the bitcoin
 912 team in Debian, you can easily test the package in Debian Squeeze
 913 using the following steps to get a set of working packages:</p>
 914
 915 <blockquote><pre>
 916 git clone git://git.debian.org/git/collab-maint/bitcoin
 917 cd bitcoin
 918 DEB_MAINTAINER_MODE=1 DEB_BUILD_OPTIONS=noupnp fakeroot debian/rules clean
 919 DEB_BUILD_OPTIONS=noupnp git-buildpackage --git-ignore-new
 920 </pre></blockquote>
 921
 922 <p>You might have to install some build dependencies as well.  The
 923 list of commands should give you two packages, bitcoind and
 924 bitcoin-qt, ready for use in a Squeeze environment.  Note that the
 925 client will download the complete set of bitcoin "blocks", which need
 926 around 5.6 GiB of data on my machine at the moment.  Make sure your
 927 ~/.bitcoin/ directory have lots of spare room if you want to download
 928 all the blocks.  The client will warn if the disk is getting full, so
 929 there is not really a problem if you got too little room, but you will
 930 not be able to get all the features out of the client.</p>
 931
 932 <p>As usual, if you use bitcoin and want to show your support of my
 933 activities, please send Bitcoin donations to my address
