14 <description>&lt;p&gt;Yesterday, I
15 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html&quot;&gt;asked
16 for testers&lt;/a&gt; for my prototype for making Debian better at handling
17 pluggable hardware devices, which I
18 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html&quot;&gt;set
19 out to create&lt;/a&gt; earlier this month. Several valuable testers showed
20 up, and caused me to really want to to open up the development to more
21 people. But before I did this, I want to come up with a sensible name
22 for this project. Today I finally decided on a new name, and I have
23 renamed the project from hw-support-handler to this new name. In the
24 process, I moved the source to git and made it available as a
25 &lt;a href=&quot;http://anonscm.debian.org/gitweb/?p=collab-maint/isenkram.git&quot;&gt;collab-maint&lt;/a&gt;
26 repository in Debian. The new name? It is &lt;strong&gt;Isenkram&lt;/strong&gt;.
27 To fetch and build the latest version of the source, use&lt;/p&gt;
28
29 &lt;pre&gt;
30 git clone git://anonscm.debian.org/collab-maint/isenkram.git
31 cd isenkram &amp;&amp; git-buildpackage -us -uc
32 &lt;/pre&gt;
33
34 &lt;p&gt;I have not yet adjusted all files to use the new name yet. If you
35 want to hack on the source or improve the package, please go ahead.
36 But please talk to me first on IRC or via email before you do major
37 changes, to make sure we do not step on each others toes. :)&lt;/p&gt;
38
39 &lt;p&gt;If you wonder what &#39;isenkram&#39; is, it is a Norwegian word for iron
40 stuff, typically meaning tools, nails, screws, etc. Typical hardware
41 stuff, in other words. I&#39;ve been told it is the Norwegian variant of
42 the German word eisenkram, for those that are familiar with that
43 word.&lt;/p&gt;
44
45 &lt;p&gt;&lt;strong&gt;Update 2013-01-26&lt;/strong&gt;: Added -us -us to build
46 instructions, to avoid confusing people with an error from the signing
47 process.&lt;/p&gt;

52 <title>First prototype ready making hardware easier to use in Debian</title>

54 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html</guid>
55 <pubDate>Mon, 21 Jan 2013 12:00:00 +0100</pubDate>
56 <description>&lt;p&gt;Early this month I set out to try to
57 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html&quot;&gt;improve
58 the Debian support for pluggable hardware devices&lt;/a&gt;. Now my
59 prototype is working, and it is ready for a larger audience. To test
60 it, fetch the
61 &lt;a href=&quot;http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/&quot;&gt;source
62 from the Debian Edu subversion repository&lt;/a&gt;, build and install the
63 package. You might have to log out and in again activate the
64 autostart script.&lt;/p&gt;
65
66 &lt;p&gt;The design is simple:&lt;/p&gt;
67
68 &lt;ul&gt;
69
70 &lt;li&gt;Add desktop entry in /usr/share/autostart/ causing a program
71 hw-support-handlerd to start when the user log in.&lt;/li&gt;
72
73 &lt;li&gt;This program listen for kernel events about new hardware (directly
74 from the kernel like udev does), not using HAL dbus events as I
75 initially did.&lt;/li&gt;
76
77 &lt;li&gt;When new hardware is inserted, look up the hardware modalias in
78 the APT database, a database
79 &lt;a href=&quot;http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=markup&quot;&gt;available
80 via HTTP&lt;/a&gt; and a database available as part of the package.&lt;/li&gt;
81
82 &lt;li&gt;If a package is mapped to the hardware in question, the package
83 isn&#39;t installed yet and this is the first time the hardware was
84 plugged in, show a desktop notification suggesting to install the
85 package or packages.&lt;/li&gt;
86
87 &lt;li&gt;If the user click on the &#39;install package now&#39; button, ask
88 aptdaemon via the PackageKit API to install the requrired package.&lt;/li&gt;
89
90 &lt;li&gt;aptdaemon ask for root password or sudo password, and install the
91 package while showing progress information in a window.&lt;/li&gt;
92
93 &lt;/ul&gt;
94
95 &lt;p&gt;I still need to come up with a better name for the system. Here
96 are some screen shots showing the prototype in action. First the
97 notification, then the password request, and finally the request to
98 approve all the dependencies. Sorry for the Norwegian Bokmål GUI.&lt;/p&gt;
99
100 &lt;p&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-1-notification.png&quot;&gt;
101 &lt;br&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-2-password.png&quot;&gt;
102 &lt;br&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-3-dependencies.png&quot;&gt;
103 &lt;br&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-4-installing.png&quot;&gt;
104 &lt;br&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-21-hw-support-5-installing-details.png&quot; width=&quot;70%&quot;&gt;&lt;/p&gt;
105
106 &lt;p&gt;The prototype still need to be improved with longer timeouts, but
107 is already useful. The database of hardware to package mappings also
108 need more work. It is currently compatible with the Ubuntu way of
109 storing such information in the package control file, but could be
110 changed to use other formats instead or in addition to the current
111 method. I&#39;ve dropped the use of discover for this mapping, as the
112 modalias approach is more flexible and easier to use on Linux as long
113 as the Linux kernel expose its modalias strings directly.&lt;/p&gt;
114
115 &lt;p&gt;&lt;strong&gt;Update 2013-01-21 16:50&lt;/strong&gt;: Due to popular demand,
116 here is the command required to check out and build the source: Use
117 &#39;&lt;tt&gt;svn checkout
118 svn://svn.debian.org/debian-edu/trunk/src/hw-support-handler/; cd
119 hw-support-handler; debuild&lt;/tt&gt;&#39;. If you lack debuild, install the
120 devscripts package.&lt;/p&gt;
121
122 &lt;p&gt;&lt;strong&gt;Update 2013-01-23 12:00&lt;/strong&gt;: The project is now
123 renamed to Isenkram and the source moved from the Debian Edu
124 subversion repository to a Debian collab-maint git repository. See
125 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Welcome_to_the_world__Isenkram_.html&quot;&gt;build
126 instructions&lt;/a&gt; for details.&lt;/p&gt;

135 <description>&lt;p&gt;This Christmas my trusty old laptop died. It died quietly and
136 suddenly in bed. With a quiet whimper, it went completely quiet and
137 black. The power button was no longer able to turn it on. It was a
138 IBM Thinkpad X41, and the best laptop I ever had. Better than both
139 Thinkpads X30, X31, X40, X60, X61 and X61S. Far better than the
140 Compaq I had before that. Now I need to find a replacement. To keep
141 going during Christmas, I moved the one year old SSD disk to my old
142 X40 where it fitted (only one I had left that could use it), but it is
143 not a durable solution.
144
145 &lt;p&gt;My laptop needs are fairly modest. This is my wishlist from when I
146 got a new one more than 10 years ago. It still holds true.:)&lt;/p&gt;
147
148 &lt;ul&gt;
149
150 &lt;li&gt;Lightweight (around 1 kg) and small volume (preferably smaller
151 than A4).&lt;/li&gt;
152 &lt;li&gt;Robust, it will be in my backpack every day.&lt;/li&gt;
153 &lt;li&gt;Three button mouse and a mouse pin instead of touch pad.&lt;/li&gt;
154 &lt;li&gt;Long battery life time. Preferable a week.&lt;/li&gt;
155 &lt;li&gt;Internal WIFI network card.&lt;/li&gt;
156 &lt;li&gt;Internal Twisted Pair network card.&lt;/li&gt;
157 &lt;li&gt;Some USB slots (2-3 is plenty)&lt;/li&gt;
158 &lt;li&gt;Good keyboard - similar to the Thinkpad.&lt;/li&gt;
159 &lt;li&gt;Video resolution at least 1024x768, with size around 12&quot; (A4 paper
160 size).&lt;/li&gt;
161 &lt;li&gt;Hardware supported by Debian Stable, ie the default kernel and
162 X.org packages.&lt;/li&gt;
163 &lt;li&gt;Quiet, preferably fan free (or at least not using the fan most of
164 the time).
165
166 &lt;/ul&gt;
167
168 &lt;p&gt;You will notice that there are no RAM and CPU requirements in the
169 list. The reason is simply that the specifications on laptops the
170 last 10-15 years have been sufficient for my needs, and I have to look
171 at other features to choose my laptop. But are there still made as
172 robust laptops as my X41? The Thinkpad X60/X61 proved to be less
173 robust, and Thinkpads seem to be heading in the wrong direction since
174 Lenovo took over. But I&#39;ve been told that X220 and X1 Carbon might
175 still be useful.&lt;/p&gt;
176
177 &lt;p&gt;Perhaps I should rethink my needs, and look for a pad with an
178 external keyboard? I&#39;ll have to check the
179 &lt;a href=&quot;http://www.linux-laptop.net/&quot;&gt;Linux Laptops site&lt;/a&gt; for
180 well-supported laptops, or perhaps just buy one preinstalled from one
181 of the vendors listed on the &lt;a href=&quot;http://linuxpreloaded.com/&quot;&gt;Linux
182 Pre-loaded site&lt;/a&gt;.&lt;/p&gt;

187 <title>How to find a browser plugin supporting a given MIME type</title>
188 <link>http://people.skolelinux.org/pere/blog/How_to_find_a_browser_plugin_supporting_a_given_MIME_type.html</link>
189 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/How_to_find_a_browser_plugin_supporting_a_given_MIME_type.html</guid>
190 <pubDate>Fri, 18 Jan 2013 10:40:00 +0100</pubDate>
191 <description>&lt;p&gt;Some times I try to figure out which Iceweasel browser plugin to
192 install to get support for a given MIME type. Thanks to
193 &lt;a href=&quot;https://wiki.ubuntu.com/MozillaTeam/Plugins&quot;&gt;specifications
194 done by Ubuntu&lt;/a&gt; and Mozilla, it is possible to do this in Debian.
195 Unfortunately, not very many packages provide the needed meta
196 information, Anyway, here is a small script to look up all browser
197 plugin packages announcing ther MIME support using this specification:&lt;/p&gt;
198
199 &lt;pre&gt;
200 #!/usr/bin/python
201 import sys
202 import apt
203 def pkgs_handling_mimetype(mimetype):
204 cache = apt.Cache()
205 cache.open(None)
206 thepkgs = []
207 for pkg in cache:
208 version = pkg.candidate
209 if version is None:
210 version = pkg.installed
211 if version is None:
212 continue
213 record = version.record
214 if not record.has_key(&#39;Npp-MimeType&#39;):
215 continue
216 mime_types = record[&#39;Npp-MimeType&#39;].split(&#39;,&#39;)
217 for t in mime_types:
218 t = t.rstrip().strip()
219 if t == mimetype:
220 thepkgs.append(pkg.name)
221 return thepkgs
222 mimetype = &quot;audio/ogg&quot;
223 if 1 &lt; len(sys.argv):
224 mimetype = sys.argv[1]
225 print &quot;Browser plugin packages supporting %s:&quot; % mimetype
226 for pkg in pkgs_handling_mimetype(mimetype):
227 print &quot; %s&quot; %pkg
228 &lt;/pre&gt;
229
230 &lt;p&gt;It can be used like this to look up a given MIME type:&lt;/p&gt;
231
232 &lt;pre&gt;
233 % ./apt-find-browserplug-for-mimetype
234 Browser plugin packages supporting audio/ogg:
235 gecko-mediaplayer
236 % ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
237 Browser plugin packages supporting application/x-shockwave-flash:
238 browser-plugin-gnash
239 %
240 &lt;/pre&gt;
241
242 &lt;p&gt;In Ubuntu this mechanism is combined with support in the browser
243 itself to query for plugins and propose to install the needed
244 packages. It would be great if Debian supported such feature too. Is
245 anyone working on adding it?&lt;/p&gt;
246
247 &lt;p&gt;&lt;strong&gt;Update 2013-01-18 14:20&lt;/strong&gt;: The Debian BTS
248 request for icweasel support for this feature is
249 &lt;a href=&quot;http://bugs.debian.org/484010&quot;&gt;#484010&lt;/a&gt; from 2008 (and
250 &lt;a href=&quot;http://bugs.debian.org/698426&quot;&gt;#698426&lt;/a&gt; from today). Lack
251 of manpower and wish for a different design is the reason thus feature
252 is not yet in iceweasel from Debian.&lt;/p&gt;

261 <description>&lt;p&gt;The &lt;a href=&quot;http://wiki.debian.org/AppStreamDebianProposal&quot;&gt;DEP-11
262 proposal to add AppStream information to the Debian archive&lt;/a&gt;, is a
263 proposal to make it possible for a Desktop application to propose to
264 the user some package to install to gain support for a given MIME
265 type, font, library etc. that is currently missing. With such
266 mechanism in place, it would be possible for the desktop to
267 automatically propose and install leocad if some LDraw file is
268 downloaded by the browser.&lt;/p&gt;
269
270 &lt;p&gt;To get some idea about the current content of the archive, I decided
271 to write a simple program to extract all .desktop files from the
272 Debian archive and look up the claimed MIME support there. The result
273 can be found on the
274 &lt;a href=&quot;http://ftp.skolelinux.org/pub/AppStreamTest&quot;&gt;Skolelinux FTP
275 site&lt;/a&gt;. Using the collected information, it become possible to
276 answer the question in the title. Here are the 20 most supported MIME
277 types in Debian stable (Squeeze), testing (Wheezy) and unstable (Sid).
278 The complete list is available from the link above.&lt;/p&gt;

364 issues.&lt;/p&gt;

372 <title>Using modalias info to find packages handling my hardware</title>
373 <link>http://people.skolelinux.org/pere/blog/Using_modalias_info_to_find_packages_handling_my_hardware.html</link>
374 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Using_modalias_info_to_find_packages_handling_my_hardware.html</guid>
375 <pubDate>Tue, 15 Jan 2013 08:00:00 +0100</pubDate>
376 <description>&lt;p&gt;Yesterday, I wrote about the
377 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html&quot;&gt;modalias
378 values provided by the Linux kernel&lt;/a&gt; following my hope for
379 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html&quot;&gt;better
380 dongle support in Debian&lt;/a&gt;. Using this knowledge, I have tested how
381 modalias values attached to package names can be used to map packages
382 to hardware. This allow the system to look up and suggest relevant
383 packages when I plug in some new hardware into my machine, and replace
384 discover and discover-data as the database used to map hardware to
385 packages.&lt;/p&gt;
386
387 &lt;p&gt;I create a modaliases file with entries like the following,
388 containing package name, kernel module name (if relevant, otherwise
389 the package name) and globs matching the relevant hardware
390 modalias.&lt;/p&gt;
391
392 &lt;p&gt;&lt;blockquote&gt;
393 Package: package-name
394 &lt;br&gt;Modaliases: module(modaliasglob, modaliasglob, modaliasglob)&lt;/p&gt;
395 &lt;/blockquote&gt;&lt;/p&gt;
396
397 &lt;p&gt;It is fairly trivial to write code to find the relevant packages
398 for a given modalias value using this file.&lt;/p&gt;
399
400 &lt;p&gt;An entry like this would suggest the video and picture application
401 cheese for many USB web cameras (interface bus class 0E01):&lt;/p&gt;
402
403 &lt;p&gt;&lt;blockquote&gt;
404 Package: cheese
405 &lt;br&gt;Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)&lt;/p&gt;
406 &lt;/blockquote&gt;&lt;/p&gt;
407
408 &lt;p&gt;An entry like this would suggest the pcmciautils package when a
409 CardBus bridge (bus class 0607) PCI device is present:&lt;/p&gt;
410
411 &lt;p&gt;&lt;blockquote&gt;
412 Package: pcmciautils
413 &lt;br&gt;Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
414 &lt;/blockquote&gt;&lt;/p&gt;
415
416 &lt;p&gt;An entry like this would suggest the package colorhug-client when
417 plugging in a ColorHug with USB IDs 04D8:F8DA:&lt;/p&gt;
418
419 &lt;p&gt;&lt;blockquote&gt;
420 Package: colorhug-client
421 &lt;br&gt;Modaliases: colorhug-client(usb:v04D8pF8DAd*)&lt;/p&gt;
422 &lt;/blockquote&gt;&lt;/p&gt;
423
424 &lt;p&gt;I believe the format is compatible with the format of the Packages
425 file in the Debian archive. Ubuntu already uses their Packages file
426 to store their mappings from packages to hardware.&lt;/p&gt;
427
428 &lt;p&gt;By adding a XB-Modaliases: header in debian/control, any .deb can
429 announce the hardware it support in a way my prototype understand.
430 This allow those publishing packages in an APT source outside the
431 Debian archive as well as those backporting packages to make sure the
432 hardware mapping are included in the package meta information. I&#39;ve
433 tested such header in the pymissile package, and its modalias mapping
434 is working as it should with my prototype. It even made it to Ubuntu
435 Raring.&lt;/p&gt;
436
437 &lt;p&gt;To test if it was possible to look up supported hardware using only
438 the shell tools available in the Debian installer, I wrote a shell
439 implementation of the lookup code. The idea is to create files for
440 each modalias and let the shell do the matching. Please check out and
441 try the
442 &lt;a href=&quot;http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co&quot;&gt;hw-support-lookup&lt;/a&gt;
443 shell script. It run without any extra dependencies and fetch the
444 hardware mappings from the Debian archive and the subversion
445 repository where I currently work on my prototype.&lt;/p&gt;
446
447 &lt;p&gt;When I use it on a machine with a yubikey inserted, it suggest to
448 install yubikey-personalization:&lt;/p&gt;
449
450 &lt;p&gt;&lt;blockquote&gt;
451 % ./hw-support-lookup
452 &lt;br&gt;yubikey-personalization
453 &lt;br&gt;%
454 &lt;/blockquote&gt;&lt;/p&gt;
455
456 &lt;p&gt;When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
457 propose to install the pcmciautils package:&lt;/p&gt;
458
459 &lt;p&gt;&lt;blockquote&gt;
460 % ./hw-support-lookup
461 &lt;br&gt;pcmciautils
462 &lt;br&gt;%
463 &lt;/blockquote&gt;&lt;/p&gt;
464
465 &lt;p&gt;If you know of any hardware-package mapping that should be added to
466 &lt;a href=&quot;http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co&quot;&gt;my
467 database&lt;/a&gt;, please tell me about it.&lt;/p&gt;
468
469 &lt;p&gt;It could be possible to generate several of the mappings between
470 packages and hardware. One source would be to look at packages with
471 kernel modules, ie packages with *.ko files in /lib/modules/, and
472 extract their modalias information. Another would be to look at
473 packages with udev rules, ie packages with files in
474 /lib/udev/rules.d/, and extract their vendor/model information to
475 generate a modalias matching rule. I have not tested any of these to
476 see if it work.&lt;/p&gt;
477
478 &lt;p&gt;If you want to help implementing a system to let us propose what
479 packages to install when new hardware is plugged into a Debian
480 machine, please send me an email or talk to me on
481 &lt;a href=&quot;irc://irc.debian.org/%23debian-devel&quot;&gt;#debian-devel&lt;/a&gt;.&lt;/p&gt;

489 <pubDate>Mon, 14 Jan 2013 11:20:00 +0100</pubDate>
490 <description>&lt;p&gt;While looking into how to look up Debian packages based on hardware
491 information, to find the packages that support a given piece of
492 hardware, I refreshed my memory regarding modalias values, and decided
493 to document the details. Here are my findings so far, also available
494 in
495 &lt;a href=&quot;http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/&quot;&gt;the
496 Debian Edu subversion repository&lt;/a&gt;:
497
498 &lt;p&gt;&lt;strong&gt;Modalias decoded&lt;/strong&gt;&lt;/p&gt;
499
500 &lt;p&gt;This document try to explain what the different types of modalias
501 values stands for. It is in part based on information from
502 &amp;lt;URL: &lt;a href=&quot;https://wiki.archlinux.org/index.php/Modalias&quot;&gt;https://wiki.archlinux.org/index.php/Modalias&lt;/a&gt; &amp;gt;,
503 &amp;lt;URL: &lt;a href=&quot;http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device&quot;&gt;http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device&lt;/a&gt; &amp;gt;,
504 &amp;lt;URL: &lt;a href=&quot;http://code.metager.de/source/history/linux/stable/scripts/mod/file2alias.c&quot;&gt;http://code.metager.de/source/history/linux/stable/scripts/mod/file2alias.c&lt;/a&gt; &amp;gt; and
505 &amp;lt;URL: &lt;a href=&quot;http://cvs.savannah.gnu.org/viewvc/dmidecode/dmidecode.c?root=dmidecode&amp;view=markup&quot;&gt;http://cvs.savannah.gnu.org/viewvc/dmidecode/dmidecode.c?root=dmidecode&amp;view=markup&lt;/a&gt; &amp;gt;.
506
507 &lt;p&gt;The modalias entries for a given Linux machine can be found using
508 this shell script:&lt;/p&gt;
509
510 &lt;pre&gt;
511 find /sys -name modalias -print0 | xargs -0 cat | sort -u
512 &lt;/pre&gt;
513
514 &lt;p&gt;The supported modalias globs for a given kernel module can be found
515 using modinfo:&lt;/p&gt;
516
517 &lt;pre&gt;
518 % /sbin/modinfo psmouse | grep alias:
519 alias: serio:ty05pr*id*ex*
520 alias: serio:ty01pr*id*ex*
521 %
522 &lt;/pre&gt;
523
524 &lt;p&gt;&lt;strong&gt;PCI subtype&lt;/strong&gt;&lt;/p&gt;
525
526 &lt;p&gt;A typical PCI entry can look like this. This is an Intel Host
527 Bridge memory controller:&lt;/p&gt;
528
529 &lt;p&gt;&lt;blockquote&gt;
530 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
531 &lt;/blockquote&gt;&lt;/p&gt;
532
533 &lt;p&gt;This represent these values:&lt;/p&gt;
534
535 &lt;pre&gt;
536 v 00008086 (vendor)
537 d 00002770 (device)
538 sv 00001028 (subvendor)
539 sd 000001AD (subdevice)
540 bc 06 (bus class)
541 sc 00 (bus subclass)
542 i 00 (interface)
543 &lt;/pre&gt;
544
545 &lt;p&gt;The vendor/device values are the same values outputted from &#39;lspci
546 -n&#39; as 8086:2770. The bus class/subclass is also shown by lspci as
547 0600. The 0600 class is a host bridge. Other useful bus values are
548 0300 (VGA compatible card) and 0200 (Ethernet controller).&lt;/p&gt;
549
550 &lt;p&gt;Not sure how to figure out the interface value, nor what it
551 means.&lt;/p&gt;
552
553 &lt;p&gt;&lt;strong&gt;USB subtype&lt;/strong&gt;&lt;/p&gt;
554
555 &lt;p&gt;Some typical USB entries can look like this. This is an internal
556 USB hub in a laptop:&lt;/p&gt;
557
558 &lt;p&gt;&lt;blockquote&gt;
559 usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
560 &lt;/blockquote&gt;&lt;/p&gt;
561
562 &lt;p&gt;Here is the values included in this alias:&lt;/p&gt;
563
564 &lt;pre&gt;
565 v 1D6B (device vendor)
566 p 0001 (device product)
567 d 0206 (bcddevice)
568 dc 09 (device class)
569 dsc 00 (device subclass)
570 dp 00 (device protocol)
571 ic 09 (interface class)
572 isc 00 (interface subclass)
573 ip 00 (interface protocol)
574 &lt;/pre&gt;
575
576 &lt;p&gt;The 0900 device class/subclass means hub. Some times the relevant
577 class is in the interface class section. For a simple USB web camera,
578 these alias entries show up:&lt;/p&gt;
579
580 &lt;p&gt;&lt;blockquote&gt;
581 usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
582 &lt;br&gt;usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
583 &lt;br&gt;usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
584 &lt;br&gt;usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
585 &lt;/blockquote&gt;&lt;/p&gt;
586
587 &lt;p&gt;Interface class 0E01 is video control, 0E02 is video streaming (aka
588 camera), 0101 is audio control device and 0102 is audio streaming (aka
589 microphone). Thus this is a camera with microphone included.&lt;/p&gt;
590
591 &lt;p&gt;&lt;strong&gt;ACPI subtype&lt;/strong&gt;&lt;/p&gt;
592
593 &lt;p&gt;The ACPI type is used for several non-PCI/USB stuff. This is an IR
594 receiver in a Thinkpad X40:&lt;/p&gt;
595
596 &lt;p&gt;&lt;blockquote&gt;
597 acpi:IBM0071:PNP0511:
598 &lt;/blockquote&gt;&lt;/p&gt;
599
600 &lt;p&gt;The values between the colons are IDs.&lt;/p&gt;
601
602 &lt;p&gt;&lt;strong&gt;DMI subtype&lt;/strong&gt;&lt;/p&gt;
603
604 &lt;p&gt;The DMI table contain lots of information about the computer case
605 and model. This is an entry for a IBM Thinkpad X40, fetched from
606 /sys/devices/virtual/dmi/id/modalias:&lt;/p&gt;
607
608 &lt;p&gt;&lt;blockquote&gt;
609 dmi:bvnIBM:bvr1UETB6WW(1.66):bd06/15/2005:svnIBM:pn2371H4G:pvrThinkPadX40:rvnIBM:rn2371H4G:rvrNotAvailable:cvnIBM:ct10:cvrNotAvailable:
610 &lt;/blockquote&gt;&lt;/p&gt;
611
612 &lt;p&gt;The values present are&lt;/p&gt;
613
614 &lt;pre&gt;
615 bvn IBM (BIOS vendor)
616 bvr 1UETB6WW(1.66) (BIOS version)
617 bd 06/15/2005 (BIOS date)
618 svn IBM (system vendor)
619 pn 2371H4G (product name)
620 pvr ThinkPadX40 (product version)
621 rvn IBM (board vendor)
622 rn 2371H4G (board name)
623 rvr NotAvailable (board version)
624 cvn IBM (chassis vendor)
625 ct 10 (chassis type)
626 cvr NotAvailable (chassis version)
627 &lt;/pre&gt;
628
629 &lt;p&gt;The chassis type 10 is Notebook. Other interesting values can be
630 found in the dmidecode source:&lt;/p&gt;
631
632 &lt;pre&gt;
633 3 Desktop
634 4 Low Profile Desktop
635 5 Pizza Box
636 6 Mini Tower
637 7 Tower
638 8 Portable
639 9 Laptop
640 10 Notebook
641 11 Hand Held
642 12 Docking Station
643 13 All In One
644 14 Sub Notebook
645 15 Space-saving
646 16 Lunch Box
647 17 Main Server Chassis
648 18 Expansion Chassis
649 19 Sub Chassis
650 20 Bus Expansion Chassis
651 21 Peripheral Chassis
652 22 RAID Chassis
653 23 Rack Mount Chassis
654 24 Sealed-case PC
655 25 Multi-system
656 26 CompactPCI
657 27 AdvancedTCA
658 28 Blade
659 29 Blade Enclosing
660 &lt;/pre&gt;
661
662 &lt;p&gt;The chassis type values are not always accurately set in the DMI
663 table. For example my home server is a tower, but the DMI modalias
664 claim it is a desktop.&lt;/p&gt;
665
666 &lt;p&gt;&lt;strong&gt;SerIO subtype&lt;/strong&gt;&lt;/p&gt;
667
668 &lt;p&gt;This type is used for PS/2 mouse plugs. One example is from my
669 test machine:&lt;/p&gt;
670
671 &lt;p&gt;&lt;blockquote&gt;
672 serio:ty01pr00id00ex00
673 &lt;/blockquote&gt;&lt;/p&gt;
674
675 &lt;p&gt;The values present are&lt;/p&gt;
676
677 &lt;pre&gt;
678 ty 01 (type)
679 pr 00 (prototype)
680 id 00 (id)
681 ex 00 (extra)
682 &lt;/pre&gt;
683
684 &lt;p&gt;This type is supported by the psmouse driver. I am not sure what
685 the valid values are.&lt;/p&gt;
686
687 &lt;p&gt;&lt;strong&gt;Other subtypes&lt;/strong&gt;&lt;/p&gt;
688
689 &lt;p&gt;There are heaps of other modalias subtypes according to
690 file2alias.c. There is the rest of the list from that source: amba,
691 ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
692 mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
693 vmbus, x86cpu and zorro. I did not spend time documenting all of
694 these, as they do not seem relevant for my intended use with mapping
695 hardware to packages when new stuff is inserted during run time.&lt;/p&gt;
696
697 &lt;p&gt;&lt;strong&gt;Looking up kernel modules using modalias values&lt;/strong&gt;&lt;/p&gt;
698
699 &lt;p&gt;To check which kernel modules provide support for a given modalias,
700 one can use the following shell script:&lt;/p&gt;
701
702 &lt;pre&gt;
703 for id in $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \
704 echo &quot;$id&quot; ; \
705 /sbin/modprobe --show-depends &quot;$id&quot;|sed &#39;s/^/ /&#39; ; \
706 done
707 &lt;/pre&gt;
708
709 &lt;p&gt;The output can look like this (only the first few entries as the
710 list is very long on my test machine):&lt;/p&gt;
711
712 &lt;pre&gt;
713 acpi:ACPI0003:
714 insmod /lib/modules/2.6.32-5-686/kernel/drivers/acpi/ac.ko
715 acpi:device:
716 FATAL: Module acpi:device: not found.

726 [...]
727 &lt;/pre&gt;

730 packages to install when new hardware is plugged into a Debian
731 machine, please send me an email or talk to me on

735 &quot;find ... -print0 | xargs -0 cat&quot; to make sure it handle directories
736 in /sys/ with space in them.&lt;/p&gt;

744 <pubDate>Thu, 10 Jan 2013 20:40:00 +0100</pubDate>
745 <description>&lt;p&gt;As part of my investigation on how to improve the support in Debian
746 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
747 Launcher and updated the Debian package
748 &lt;a href=&quot;http://packages.qa.debian.org/pymissile&quot;&gt;pymissile&lt;/a&gt; to make
749 sure udev will fix the device permissions when it is plugged in. I
750 also added a &quot;Modaliases&quot; header to test it in the Debian archive and
751 hopefully make the package be proposed by jockey in Ubuntu when a user
752 plug in his rocket launcher. In the process I moved the source to a
753 git repository under collab-maint, to make it easier for any DD to
754 contribute. &lt;a href=&quot;http://code.google.com/p/pymissile/&quot;&gt;Upstream&lt;/a&gt;
755 is not very active, but the software still work for me even after five
756 years of relative silence. The new git repository is not listed in
757 the uploaded package yet, because I want to test the other changes a
758 bit more before I upload the new version. If you want to check out
759 the new version with a .desktop file included, visit the
760 &lt;a href=&quot;http://anonscm.debian.org/gitweb/?p=collab-maint/pymissile.git&quot;&gt;gitweb
761 view&lt;/a&gt; or use &quot;&lt;tt&gt;git clone
762 git://anonscm.debian.org/collab-maint/pymissile.git&lt;/tt&gt;&quot;.&lt;/p&gt;

770 <pubDate>Wed, 9 Jan 2013 15:40:00 +0100</pubDate>
771 <description>&lt;p&gt;One thing that annoys me with Debian and Linux distributions in
772 general, is that there is a great package management system with the
773 ability to automatically install software packages by downloading them
774 from the distribution mirrors, but no way to get it to automatically
775 install the packages I need to use the hardware I plug into my
776 machine. Even if the package to use it is easily available from the
777 Linux distribution. When I plug in a LEGO Mindstorms NXT, it could
778 suggest to automatically install the python-nxt, nbc and t2n packages
779 I need to talk to it. When I plug in a Yubikey, it could propose the
780 yubikey-personalization package. The information required to do this
781 is available, but no-one have pulled all the pieces together.&lt;/p&gt;
782
783 &lt;p&gt;Some years ago, I proposed to
784 &lt;a href=&quot;http://lists.debian.org/debian-devel/2010/05/msg01206.html&quot;&gt;use
785 the discover subsystem to implement this&lt;/a&gt;. The idea is fairly
786 simple:
787
788 &lt;ul&gt;
789
790 &lt;li&gt;Add a desktop entry in /usr/share/autostart/ pointing to a program
791 starting when a user log in.&lt;/li&gt;
792
793 &lt;li&gt;Set this program up to listen for kernel events emitted when new
794 hardware is inserted into the computer.&lt;/li&gt;
795
796 &lt;li&gt;When new hardware is inserted, look up the hardware ID in a
797 database mapping to packages, and take note of any non-installed
798 packages.&lt;/li&gt;
799
800 &lt;li&gt;Show a message to the user proposing to install the discovered
801 package, and make it easy to install it.&lt;/li&gt;
802
803 &lt;/ul&gt;
804
805 &lt;p&gt;I am not sure what the best way to implement this is, but my
806 initial idea was to use dbus events to discover new hardware, the
807 discover database to find packages and
808 &lt;a href=&quot;http://www.packagekit.org/&quot;&gt;PackageKit&lt;/a&gt; to install
809 packages.&lt;/p&gt;
810
811 &lt;p&gt;Yesterday, I found time to try to implement this idea, and the
812 draft package is now checked into
813 &lt;a href=&quot;http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/&quot;&gt;the
814 Debian Edu subversion repository&lt;/a&gt;. In the process, I updated the
815 &lt;a href=&quot;http://packages.qa.debian.org/d/discover-data.html&quot;&gt;discover-data&lt;/a&gt;
816 package to map the USB ids of LEGO Mindstorms and Yubikey devices to
817 the relevant packages in Debian, and uploaded a new version
818 2.2013.01.09 to unstable. I also discovered that the current
819 &lt;a href=&quot;http://packages.qa.debian.org/d/discover.html&quot;&gt;discover&lt;/a&gt;
820 package in Debian no longer discovered any USB devices, because
821 /proc/bus/usb/devices is no longer present. I ported it to use
822 libusb as a fall back option to get it working. The fixed package
823 version 2.1.2-6 is now in experimental (didn&#39;t upload it to unstable
824 because of the freeze).&lt;/p&gt;
825
826 &lt;p&gt;With this prototype in place, I can insert my Yubikey, and get this
827 desktop notification to show up (only once, the first time it is
828 inserted):&lt;/p&gt;
829
830 &lt;p align=&quot;center&quot;&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png&quot;&gt;&lt;/p&gt;
831
832 &lt;p&gt;For this prototype to be really useful, some way to automatically
833 install the proposed packages by pressing the &quot;Please install
834 program(s)&quot; button should to be implemented.&lt;/p&gt;
835
836 &lt;p&gt;If this idea seem useful to you, and you want to help make it
837 happen, please help me update the discover-data database with mappings
838 from hardware to Debian packages. Check if &#39;discover-pkginstall -l&#39;
839 list the package you would like to have installed when a given
840 hardware device is inserted into your computer, and report bugs using
841 reportbug if it isn&#39;t. Or, if you know of a better way to provide
842 such mapping, please let me know.&lt;/p&gt;
843
844 &lt;p&gt;This prototype need more work, and there are several questions that
845 should be considered before it is ready for production use. Is dbus
846 the correct way to detect new hardware? At the moment I look for HAL
847 dbus events on the system bus, because that is the events I could see
848 on my Debian Squeeze KDE desktop. Are there better events to use?
849 How should the user be notified? Is the desktop notification
850 mechanism the best option, or should the background daemon raise a
851 popup instead? How should packages be installed? When should they
852 not be installed?&lt;/p&gt;
853
854 &lt;p&gt;If you want to help getting such feature implemented in Debian,
855 please send me an email. :)&lt;/p&gt;

864 <description>&lt;p&gt;During Christmas, I have worked a bit on the Debian support for
865 &lt;a href=&quot;http://mindstorms.lego.com/en-us/Default.aspx&quot;&gt;LEGO Mindstorm
866 NXT&lt;/a&gt;. My son and I have played a bit with my NXT set, and I
867 discovered I had to build all the tools myself because none were
868 already in Debian Squeeze. If Debian support for LEGO is something
869 you care about, please join me on the IRC channel
870 &lt;a href=&quot;irc://irc.debian.org/%23debian-lego&quot;&gt;#debian-lego&lt;/a&gt; (server
871 irc.debian.org). There is a lot that could be done to improve the
872 Debian support for LEGO designers. For example both CAD software
873 and Mindstorm compilers are missing. :)&lt;/p&gt;

886 <description>&lt;p&gt;Her er noen lenker til tekster jeg har satt pris på å lese den
887 siste måneden.&lt;/p&gt;

894 kommenterer noen av de påstandene som er spredt via Computerworld
895 Norge de siste månedene.&lt;/li&gt;
896
897 &lt;li&gt;BankID er et opplegg der utsteder (dvs. banken eller dens
898 leverandør) sitter på alt som trengs for å bruke BankID, men har
899 lovet å ikke bruke den unntatt på oppdrag fra deg. Det er greit nok
900 for banktjenester, der banken allerede har full kontroll over
901 resultatet, men problematisk når det gjelder tilgang til
902 helseopplysninger og avtaleinngåelse med andre enn banken. Jeg
903 håper protestene brer om seg.
