Stig Hornnes i FAD tipset meg +om følgende som står i oppsumeringen til høringen om +referansekatalogen versjon 2.0, som jeg siden ved hjelp av en +innsynsforespørsel fikk tak i +<a href="http://wiki.nuug.no/uttalelser/200901-standardkatalog-v2?action=AttachFile&do=get&target=kongelig-resolusjon.pdf">PDF-utgaven av</a> +datert 2009-06-03 (saksnummer 200803291, saksbehandler Henrik +Linnestad).</p> + +<p>Der står det følgende om problemstillingen:</p> + +<p><blockquote> +<strong>4.4 Patentproblematikk</strong> + +<p>NUUG og Opera ser det som særlig viktig at forslagene knyttet til +lyd og video baserer seg på de royalty-frie standardene Vorbis, Theora +og FLAC.</p> + +<p>Kommentarene relaterer seg til at enkelte standarder er åpne, men +inneholder tekniske prosedyrer som det i USA (og noen andre land som +Japan) er gitt patentrettigheter til. I vårt tilfelle berører dette +spesielt standardene Mp3 og H.264, selv om Politidirektoratet peker på +at det muligens kan være tilsvarende problematikk også for Theora og +Vorbis. Dette medfører at det i USA kan kreves royalties for bruk av +tekniske løsninger knyttet til standardene, et krav som også +håndheves. Patenter kan imidlertid bare hevdes i de landene hvor +patentet er gitt, så amerikanske patenter gjelder ikke andre steder +enn USA.</p> + +<p>Spesielt for utvikling av fri programvare er patenter +problematisk. GPL, en "grunnleggende" lisens for distribusjon av fri +programvare, avviser at programvare kan distribueres under denne +lisensen hvis det inneholder referanser til patenterte rutiner som +utløser krav om royalties. Det er imidlertid uproblematisk å +distribuere fri programvareløsninger under GPL som benytter de +aktuelle standardene innen eller mellom land som ikke anerkjenner +patentene. Derfor finner vi også flere implementeringer av Mp3 og +H.264 som er fri programvare, lisensiert under GPL.</p> + +<p>I Norge og EU er patentlovgivningen langt mer restriktiv enn i USA, +men det er også her mulig å få patentert metoder for løsning av et +problem som relaterer seg til databehandling. Det er AIF bekjent ikke +relevante patenter i EU eller Norge hva gjelder H.264 og Mp3, men +muligheten for at det finnes patenter uten at det er gjort krav om +royalties eller at det senere vil gis slike patenter kan ikke helt +avvises.</p> + +<p>AIF mener det er et behov for å gi offentlige virksomheter mulighet +til å benytte antatt royaltyfrie åpne standarder som et likeverdig +alternativ eller i tillegg til de markedsledende åpne standardene.</p> + +</blockquote></p> + +<p>Det ser dermed ikke ut til at de har vurdert patentspørsmålet i +sammenheng med opphavsrettsvilkår slik de er formulert for f.eks. +Apple Final Cut Pro, Adobe Premiere Pro, Avid og Sorenson-verktøyene, +der det kreves brukstillatelse for patenter som ikke er gyldige i +Norge for å bruke disse verktøyene til annet en personlig og ikke +kommersiell aktivitet når det gjelder H.264-video.

But this right is under serious attack these days.</p> + +<p>A while back it occurred to me that one way to make the dragnet +surveillance conducted by NSA, GCHQ, FRA and others (and confirmed by +the whisleblower Snowden) more expensive for Internet email, +is to deliver all email using SMTP via Tor. Such SMTP option would be +a nice addition to the FreedomBox project if we could send email +between FreedomBox machines without leaking metadata about the emails +to the people peeking on the wire. I +<a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2014-October/006493.html">proposed +this on the FreedomBox project mailing list in October</a> and got a +lot of useful feedback and suggestions. It also became obvious to me +that this was not a novel idea, as the same idea was tested and +documented by Johannes Berg as early as 2006, and both +<a href="https://github.com/pagekite/Mailpile/wiki/SMTorP">the +Mailpile</a> and <a href="http://dee.su/cables">the Cables</a> systems +propose a similar method / protocol to pass emails between users.</p> + +<p>To implement such system one need to set up a Tor hidden service +providing the SMTP protocol on port 25, and use email addresses +looking like username@hidden-service-name.onion. With such addresses +the connections to port 25 on hidden-service-name.onion using Tor will +go to the correct SMTP server. To do this, one need to configure the +Tor daemon to provide the hidden service and the mail server to accept +emails for this .onion domain. To learn more about Exim configuration +in Debian and test the design provided by Johannes Berg in his FAQ, I +set out yesterday to create a Debian package for making it trivial to +set up such SMTP over Tor service based on Debian. Getting it to work +were fairly easy, and +<a href="https://github.com/petterreinholdtsen/exim4-smtorp">the +source code for the Debian package</a> is available from github. I +plan to move it into Debian if further testing prove this to be a +useful approach.</p> + +<p>If you want to test this, set up a blank Debian machine without any +mail system installed (or run <tt>apt-get purge exim4-config</tt> to +get rid of exim4). Install tor, clone the git repository mentioned +above, build the deb and install it on the machine. Next, run +<tt>/usr/lib/exim4-smtorp/setup-exim-hidden-service</tt> and follow +the instructions to get the service up and running. Restart tor and +exim when it is done, and test mail delivery using swaks like +this:</p> + +<p><blockquote><pre> +torsocks swaks --server dutlqrrmjhtfa3vp.onion \ + --to fbx@dutlqrrmjhtfa3vp.onion +</pre></blockquote></p> + +<p>This will test the SMTP delivery using tor. Replace the email +address with your own address to test your server. :)</p> + +<p>The setup procedure is still to complex, and I hope it can be made +easier and more automatic. Especially the tor setup need more work. +Also, the package include a tor-smtp tool written in C, but its task +should probably be rewritten in some script language to make the deb +architecture independent. It would probably also make the code easier +to review. The tor-smtp tool currently need to listen on a socket for +exim to talk to it and is started using xinetd. It would be better if +no daemon and no socket is needed. I suspect it is possible to get +exim to run a command line tool for delivery instead of talking to a +socket, and hope to figure out how in a future version of this +system.</p> + +<p>Until I wipe my test machine, I can be reached using the +<tt>fbx@dutlqrrmjhtfa3vp.onion</tt> mail address, deliverable over +SMTorP. :)</p> + + + + + First Jessie based Debian Edu released (alpha0) + http://people.skolelinux.org/pere/blog/First_Jessie_based_Debian_Edu_released__alpha0_.html + http://people.skolelinux.org/pere/blog/First_Jessie_based_Debian_Edu_released__alpha0_.html + Mon, 27 Oct 2014 20:40:00 +0100 + <p>I am happy to report that I on behalf of the Debian Edu team just +sent out +<a href="https://lists.debian.org/debian-edu-announce/2014/10/msg00000.html">this +announcement</a>:</p> + +<pre> +The Debian Edu Team is pleased to announce the release of Debian Edu +Jessie 8.0+edu0~alpha0 + +Debian Edu is a complete operating system for schools.

First you visit one web page, enter the moderation password +and get a new page shown with a list of all the messages to moderate +and various options for each email address. This take a while for +every list you moderate, and you need to do it regularly to do a good +job as a list moderator. But there is a quick alternative, +<a href="http://heim.ifi.uio.no/kjetilho/hacks/#listadmin">the +listadmin program</a>. It allow you to check lists for new messages +to moderate in a fraction of a second. Here is a test run on two +lists I recently took over:</p> + +<p><blockquote><pre> +% time listadmin xiph +fetching data for pkg-xiph-commits@lists.alioth.debian.org ... nothing in queue +fetching data for pkg-xiph-maint@lists.alioth.debian.org ... nothing in queue + +real 0m1.709s +user 0m0.232s +sys 0m0.012s +% +</pre></blockquote></p> + +<p>In 1.7 seconds I had checked two mailing lists and confirmed that +there are no message in the moderation queue. Every morning I +currently moderate 68 mailman lists, and it normally take around two +minutes. When I took over the two pkg-xiph lists above a few days +ago, there were 400 emails waiting in the moderator queue. It took me +less than 15 minutes to process them all using the listadmin +program.</p> + +<p>If you install +<a href="https://tracker.debian.org/pkg/listadmin">the listadmin +package</a> from Debian and create a file <tt>~/.listadmin.ini</tt> +with content like this, the moderation task is a breeze:</p> + +<p><blockquote><pre> +username username@example.org +spamlevel 23 +default discard +discard_if_reason "Posting restricted to members only. Remove us from your mail list." + +password secret +adminurl https://{domain}/mailman/admindb/{list} +mailman-list@lists.example.com + +password hidden +other-list@otherserver.example.org +</pre></blockquote></p> + +<p>There are other options to set as well. Check the manual page to +learn the details.</p> + +<p>If you are forced to moderate lists on a mailman installation where +the SSL certificate is self signed or not properly signed by a +generally accepted signing authority, you can set a environment +variable when calling listadmin to disable SSL verification:</p> + +<p><blockquote><pre> +PERL_LWP_SSL_VERIFY_HOSTNAME=0 listadmin +</pre></blockquote></p> + +<p>If you want to moderate a subset of the lists you take care of, you +can provide an argument to the listadmin script like I do in the +initial screen dump (the xiph argument). Using an argument, only +lists matching the argument string will be processed. This make it +quick to accept messages if you notice the moderation request in your +email.</p> + +<p>Without the listadmin program, I would never be the moderator of 68 +mailing lists, as I simply do not have time to spend on that if the +process was any slower. The listadmin program have saved me hours of +time I could spend elsewhere over the years.

When we install more than 2000 packages in -<a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a> using -tasksel in the installer, unpacking the binary packages take forever. -A part of the slow I/O issue was discussed in -<a href="https://bugs.debian.org/613428">bug #613428</a> about too -much file system sync-ing done by dpkg, which is the package -responsible for unpacking the binary packages. Other parts (like code -executed by postinst scripts) might also sync to disk during -installation. All this sync-ing to disk do not really make sense to -me. If the machine crash half-way through, I start over, I do not try -to salvage the half installed system. So the failure sync-ing is -supposed to protect against, hardware or system crash, is not really -relevant while the installer is running.</p> - -<p>A few days ago, I thought of a way to get rid of all the file -system sync()-ing in a fairly non-intrusive way, without the need to -change the code in several packages. The idea is not new, but I have -not heard anyone propose the approach using dpkg-divert before. It -depend on the small and clever package -<a href="https://packages.qa.debian.org/eatmydata">eatmydata</a>, which -uses LD_PRELOAD to replace the system functions for syncing data to -disk with functions doing nothing, thus allowing programs to live -dangerous while speeding up disk I/O significantly. Instead of -modifying the implementation of dpkg, apt and tasksel (which are the -packages responsible for selecting, fetching and installing packages), -it occurred to me that we could just divert the programs away, replace -them with a simple shell wrapper calling -"eatmydata&nbsp;$program&nbsp;$@", to get the same effect. -Two days ago I decided to test the idea, and wrapped up a simple -implementation for the Debian Edu udeb.</p> - -<p>The effect was stunning. In my first test it reduced the running -time of the pkgsel step (installing tasks) from 64 to less than 44 -minutes (20 minutes shaved off the installation) on an old Dell -Latitude D505 machine. I am not quite sure what the optimised time -would have been, as I messed up the testing a bit, causing the debconf -priority to get low enough for two questions to pop up during -installation. As soon as I saw the questions I moved the installation -along, but do not know how long the question were holding up the -installation. I did some more measurements using Debian Edu Jessie, -and got these results. The time measured is the time stamp in -/var/log/syslog between the "pkgsel: starting tasksel" and the -"pkgsel: finishing up" lines, if you want to do the same measurement -yourself. In Debian Edu, the tasksel dialog do not show up, and the -timing thus do not depend on how quickly the user handle the tasksel -dialog.</p> - -<p><table> - -<tr> -<th>Machine/setup</th> -<th>Original tasksel</th> -<th>Optimised tasksel</th> -<th>Reduction</th> -</tr> - -<tr> -<td>Latitude D505 Main+LTSP LXDE</td> -<td>64 min (07:46-08:50)</td> -<td><44 min (11:27-12:11)</td> -<td>>20 min 18%</td> -</tr> - -<tr> -<td>Latitude D505 Roaming LXDE</td> -<td>57 min (08:48-09:45)</td> -<td>34 min (07:43-08:17)</td> -<td>23 min 40%</td> -</tr> - -<tr> -<td>Latitude D505 Minimal</td> -<td>22 min (10:37-10:59)</td> -<td>11 min (11:16-11:27)</td> -<td>11 min 50%</td> -</tr> - -<tr> -<td>Thinkpad X200 Minimal</td> -<td>6 min (08:19-08:25)</td> -<td>4 min (08:04-08:08)</td> -<td>2 min 33%</td> -</tr> - -<tr> -<td>Thinkpad X200 Roaming KDE</td> -<td>19 min (09:21-09:40)</td> -<td>15 min (10:25-10:40)</td> -<td>4 min 21%</td> -</tr> - -</table></p> - -<p>The test is done using a netinst ISO on a USB stick, so some of the -time is spent downloading packages. The connection to the Internet -was 100Mbit/s during testing, so downloading should not be a -significant factor in the measurement. Download typically took a few -seconds to a few minutes, depending on the amount of packages being -installed.</p> - -<p>The speedup is implemented by using two hooks in -<a href="https://www.debian.org/devel/debian-installer/">Debian -Installer</a>, the pre-pkgsel.d hook to set up the diverts, and the -finish-install.d hook to remove the divert at the end of the -installation. I picked the pre-pkgsel.d hook instead of the -post-base-installer.d hook because I test using an ISO without the -eatmydata package included, and the post-base-installer.d hook in -Debian Edu can only operate on packages included in the ISO. The -negative effect of this is that I am unable to activate this -optimization for the kernel installation step in d-i. If the code is -moved to the post-base-installer.d hook, the speedup would be larger -for the entire installation.</p> - -<p>I've implemented this in the -<a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a> -git repository, and plan to provide the optimization as part of the -Debian Edu installation. If you want to test this yourself, you can -create two files in the installer (or in an udeb). One shell script -need do go into /usr/lib/pre-pkgsel.d/, with content like this:</p> - -<p><blockquote><pre> -#!/bin/sh -set -e -. /usr/share/debconf/confmodule -info() { - logger -t my-pkgsel "info: $*" -} -error() { - logger -t my-pkgsel "error: $*" -} -override_install() { - apt-install eatmydata || true - if [ -x /target/usr/bin/eatmydata ] ; then - for bin in dpkg apt-get aptitude tasksel ; do - file=/usr/bin/$bin - # Test that the file exist and have not been diverted already. - if [ -f /target$file ] ; then - info "diverting $file using eatmydata" - printf "#!/bin/sh\neatmydata $bin.distrib \"\$@\"\n" \ - > /target$file.edu - chmod 755 /target$file.edu - in-target dpkg-divert --package debian-edu-config \ - --rename --quiet --add $file - ln -sf ./$bin.edu /target$file - else - error "unable to divert $file, as it is missing." - fi - done - else - error "unable to find /usr/bin/eatmydata after installing the eatmydata pacage" - fi -} - -override_install -</pre></blockquote></p> - -<p>To clean up, another shell script should go into -/usr/lib/finish-install.d/ with code like this: - -<p><blockquote><pre> -#! /bin/sh -e -. /usr/share/debconf/confmodule -error() { - logger -t my-finish-install "error: $@" -} -remove_install_override() { - for bin in dpkg apt-get aptitude tasksel ; do - file=/usr/bin/$bin - if [ -x /target$file.edu ] ; then - rm /target$file - in-target dpkg-divert --package debian-edu-config \ - --rename --quiet --remove $file - rm /target$file.edu - else - error "Missing divert for $file." - fi - done - sync # Flush file buffers before continuing -} - -remove_install_override -</pre></blockquote></p> - -<p>In Debian Edu, I placed both code fragments in a separate script -edu-eatmydata-install and call it from the pre-pkgsel.d and -finish-install.d scripts.</p> - -<p>By now you might ask if this change should get into the normal -Debian installer too? I suspect it should, but am not sure the -current debian-installer coordinators find it useful enough. It also -depend on the side effects of the change. I'm not aware of any, but I -guess we will see if the change is safe after some more testing. -Perhaps there is some package in Debian depending on sync() and -fsync() having effect? Perhaps it should go into its own udeb, to -allow those of us wanting to enable it to do so without affecting -everyone.</p> - -<p>Update 2014-09-24: Since a few days ago, enabling this optimization -will break installation of all programs using gnutls because of -<a href="https://bugs.debian.org/702711">bug #702711.

So far I have used -subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former -were misbehaving, but those days are ended. The servers I have used -up until yesterday have been slow and some times unavailable. I hope -those problems are gone now.</p> - -<p>Behind the round robin DNS entry of the -<a href="https://sks-keyservers.net/">sks-keyservers.net</a> service -there is a pool of more than 100 keyservers which are checked every -day to ensure they are well connected and up to date. It must be -better than what I have used so far. :)</p> - -<p>Yesterdays speaker told me that the service is the default -keyserver provided by the default configuration in GnuPG, but this do -not seem to be used in Debian. Perhaps it should?</p> - -<p>Anyway, I've updated my ~/.gnupg/options file to now include this -line:</p> - -<p><blockquote><pre> -keyserver pool.sks-keyservers.net -</pre></blockquote></p> - -<p>With GnuPG version 2 one can also locate the keyserver using SRV -entries in DNS. Just for fun, I did just that at work, so now every -user of GnuPG at the University of Oslo should find a OpenGPG -keyserver automatically should their need it:</p> - -<p><blockquote><pre> -% host -t srv _pgpkey-http._tcp.uio.no -_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net. -% -</pre></blockquote></p> - -<p>Now if only -<a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the -HKP lookup protocol</a> supported finding signature paths, I would be -very happy. It can look up a given key or search for a user ID, but I -normally do not want that, but to find a trust path from my key to -another key. Given a user ID or key ID, I would like to find (and -download) the keys representing a signature path from my key to the -key in question, to be able to get a trust path between the two keys. -This is as far as I can tell not possible today. Perhaps something -for a future version of the protocol?</p> - - - - - Do you need an agreement with MPEG-LA to publish and broadcast H.264 video in Norway? - http://people.skolelinux.org/pere/blog/Do_you_need_an_agreement_with_MPEG_LA_to_publish_and_broadcast_H_264_video_in_Norway_.html - http://people.skolelinux.org/pere/blog/Do_you_need_an_agreement_with_MPEG_LA_to_publish_and_broadcast_H_264_video_in_Norway_.html - Mon, 25 Aug 2014 22:10:00 +0200 - <p>Two years later, I am still not sure if it is legal here in Norway -to use or publish a video in H.264 or MPEG4 format edited by the -commercially licensed video editors, without limiting the use to -create "personal" or "non-commercial" videos or get a license -agreement with <a href="http://www.mpegla.com">MPEG LA</a>.
