                <description>

-&lt;p&gt;6 years ago, as part of the Debian Edu development I am involved
-in, I asked for a hook in the kdm and gdm setup to run scripts as root
-when the user log out.  A bug was submitted against the xfree86-common
-package in 2004 (&lt;a href=&quot;http://bugs.debian.org/230422&quot;&gt;#230422&lt;/a&gt;),
-and revisited every time Debian Edu was working on a new release.
-Today, this finally paid off.&lt;/p&gt;
-
-&lt;p&gt;The framework for this feature was today commited to the git
-repositry for the xorg package, and the git repository for xdm has
-been updated to use this framework.  Next on my agenda is to make sure
-kdm and gdm also add code to use this framework.&lt;/p&gt;
-
-&lt;p&gt;In Debian Edu, we want to ability to run commands as root when the
-user log out, to get rid of runaway processes and do general cleanup
-after a user.  With this framework in place, we finally can do that in
-a generic way that work with all display managers using this
-framework.  My goal is to get all display managers in Debian use it,
-similar to how they use the Xsession.d framework today.&lt;p&gt;
+&lt;p&gt;Vagrant mentioned on IRC today that ltsp_config now support
+sourcing files from /usr/share/ltsp/ltsp_config.d/ on the thin
+clients, and that this can be used to fetch configuration from LDAP if
+Debian Edu choose to store configuration there.&lt;/p&gt;
+
+&lt;p&gt;Armed with this information, I got inspired and wrote a test module
+to get configuration from LDAP.  The idea is to look up the MAC
+address of the client in LDAP, and look for attributes on the form
+ltspconfigsetting=value, and use this to export SETTING=value to the
+LTSP clients.&lt;/p&gt;
+
+&lt;p&gt;The goal is to be able to store the LTSP configuration attributes
+in a &quot;computer&quot; LDAP object used by both DNS and DHCP, and thus
+allowing us to store all information about a computer in one place.&lt;/p&gt;
+
+&lt;p&gt;This is a untested draft implementation, and I welcome feedback on
+this approach.  A real LDAP schema for the ltspClientAux objectclass
+need to be written.  Comments, suggestions, etc?&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+# Store in /opt/ltsp/$arch/usr/share/ltsp/ltsp_config.d/ldap-config
+#
+# Fetch LTSP client settings from LDAP based on MAC address
+#
+# Uses ethernet address as stored in the dhcpHost objectclass using
+# the dhcpHWAddress attribute or ethernet address stored in the
+# ieee802Device objectclass with the macAddress attribute.
+#
+# This module is written to be schema agnostic, and only depend on the
+# existence of attribute names.
+#
+# The LTSP configuration variables are saved directly using a
+# ltspConfig prefix and uppercasing the rest of the attribute name.
+# To set the SERVER variable, set the ltspConfigServer attribute.
+#
+# Some LDAP schema should be created with all the relevant
+# configuration settings.  Something like this should work:
+# 
+# objectclass ( 1.1.2.2 NAME &#39;ltspClientAux&#39;
+#     SUP top
+#     AUXILIARY
+#     MAY ( ltspConfigServer $ ltsConfigSound $ ... )
+
+LDAPSERVER=$(debian-edu-ldapserver)
+if [ &quot;$LDAPSERVER&quot; ] ; then
+    LDAPBASE=$(debian-edu-ldapserver -b)
+    for MAC in $(LANG=C ifconfig |grep -i hwaddr| awk &#39;{print $5}&#39;|sort -u) ; do
+       filter=&quot;(|(dhcpHWAddress=ethernet $MAC)(macAddress=$MAC))&quot;
+       ldapsearch -h &quot;$LDAPSERVER&quot; -b &quot;$LDAPBASE&quot; -v -x &quot;$filter&quot; | \
+           grep &#39;^ltspConfig&#39; | while read attr value ; do
+           # Remove prefix and convert to upper case
+           attr=$(echo $attr | sed &#39;s/^ltspConfig//i&#39; | tr a-z A-Z)
+           # bass value on to clients
+           eval &quot;$attr=$value; export $attr&quot;
+       done
+    done
+fi
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;I&#39;m not sure this shell construction will work, because I suspect
+the while block might end up in a subshell causing the variables set
+there to not show up in ltsp-config, but if that is the case I am sure
+the code can be restructured to make sure the variables are passed on.
+I expect that can be solved with some testing. :)&lt;/p&gt;
+
+&lt;p&gt;If you want to help out with implementing this for Debian Edu,
+please contact us on debian-edu@lists.debian.org.&lt;/p&gt;

-&lt;p&gt;Den norske bokbransjen har
-&lt;a href=&quot;http://www.digi.no/823912/nei-til-moms-paa-e-boker&quot;&gt;bedt om at
-digitale bøker må få mva-fritak&lt;/a&gt; slik papirbøker har det, og
-&lt;a href=&quot;http://www.digi.no/836875/moms-paa-alt-digitalt-innhold&quot;&gt;finansdepartementet
-har sagt nei&lt;/a&gt;.  Det er et interessant spørsmål om digitale bøker
-bør ha mva-fritak eller ikke, og svaret er ikke så enkelt som et ja
-eller nei.
-&lt;a href=&quot;http://www.digi.no/836925/norske-e-boker-truet-av-moms&quot;&gt;Enkelte
-medlemmer&lt;/a&gt; av bokbransjen truer med å droppe den planlagte
-lanseringen av norske digitale bøker med digitale restriksjonsmekanismer
-(DRM) som de har snakket om å gjennomføre nå i vår, og det må de
-gjerne gjøre for min del.&lt;/p&gt;
-
-&lt;p&gt;Papirbøker har mva-fritak pga. at de fremmer kultur- og
-kunnskapsspredning.  Digitale bøker uten digitale
-restriksjonsmekanismer (DRM) fremmer kultur- og kunnskapsspredning,
-mens digitale bøker med DRM hindrer kultur og kunnskapsspredning.
-Digitale bøker uten DRM bør få mva-fritak da det er salg av bøker på
-lik linje med salg av papirbøker, mens digitale bøker med DRM ikke bør
-få det da det er utleie av bøker og ikke salg.&lt;/p&gt;
-
-&lt;p&gt;Jeg foretrekker å kjøpe bøker, og velger dermed å la være å bruke
-DRM-belastede digitale bøker.  Vet ikke helt hva jeg ville være villig
-til å betale for å leie en bok, men tror ikke det er mange kronene.
-Heldigvis er det mye bøker tilgjengelig uten slike restriksjoner, og
-de som vil ha tak i engelske bøker kan laste ned bøker som er
-tilgjengelig uten bruksbegresninger fra &lt;a href=&quot;http://www.archive.org/&quot;&gt;The
-Internet Archive&lt;/a&gt;. Der er det pr. i dag 1 889 313 bøker
-tilgjengelig. De er tilgjengelig i flere formater. Besøk
-&lt;a href=&quot;http://www.archive.org/details/texts&quot;&gt;oversikten over tekster
-der&lt;/a&gt; for å se hva de har.
+&lt;p&gt;Since
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/LUMA__a_very_nice_LDAP_GUI.html&quot;&gt;my
+last post&lt;/a&gt; about available LDAP tools in Debian, I was told about a
+LDAP GUI that is even better than luma.  The java application
+&lt;a href=&quot;http://jxplorer.org/&quot;&gt;jXplorer&lt;/a&gt; is claimed to be capable of
+moving LDAP objects and subtrees using drag-and-drop, and can
+authenticate using Kerberos.  I have only tested the Kerberos
+authentication, but do not have a LDAP setup allowing me to rewrite
+LDAP with my test user yet.  It is
+&lt;a href=&quot;http://packages.qa.debian.org/j/jxplorer.html&quot;&gt;available in
+Debian&lt;/a&gt; testing and unstable at the moment.  The only problem I
+have with it is how it handle errors.  If something go wrong, its
+non-intuitive behaviour require me to go through some query work list
+and remove the failing query.  Nothing big, but very annoying.&lt;/p&gt;

                <description>

-&lt;p&gt;On Tuesday, the Debian/Lenny based version of
-&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt; was finally
-shipped.  This was a major leap forward for the project, and I am very
-pleased that we finally got the release wrapped up.  Work on the first
-point release starts imediately, as we plan to get that one out a
-month after the major release, to include all fixes for bugs we found
-and fixed too late in the release process to include last Tuesday.&lt;/p&gt;
-
-&lt;p&gt;Perhaps it even is time for some partying?&lt;/p&gt;
-
-&lt;p&gt;After this first point release, my plan is to focus again on the
-next major release, based on Squeeze.  We will try to get as many of
-the fixes we need into the official Debian packages before the freeze,
-and have just a few weeks or months to make it happen.&lt;/p&gt;
+&lt;p&gt;De siste dagene har Aftenposten
+&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3718597.ece&quot;&gt;fortalt&lt;/a&gt;
+&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3724249.ece&quot;&gt;hvordan&lt;/a&gt;
+politet har brukt skriveverktøy som ikke håndterer arabisk tekst og
+tekst som skal skrives fra høyre mot venstre når de har laget
+løpeseddel for å be om informasjon fra publikum.  Resultatet har vært
+en uleselig arabisk-bit på løpeseddelen.  Feilen har oppstått når
+teksten har blitt &quot;kopiert inn i programvare som ikke har støtte for
+språk som skrives fra høyre mot venstre&quot;, og jeg er ganske sikker på
+at det er snakk om Microsoft Office i dette tilfellet.  Er det slik at
+MS Office i norsk språkdrakt ikke har støtte for tekst som skal
+skrives fra høyre mot venstre?  Jeg tror alle utgaver av
+OpenOffice.org har slik støtte, og det er jo ikke veldig vanskelig å
+la slik støtte finnes i alle utgaver av et program hvis støtten først
+er utviklet.  Aftenpostens melding får meg til å undre om problemet
+ville vært unngått hvis politiet brukte OpenOffice.org i stedet for MS
+Office.&lt;/p&gt;
+
+&lt;p&gt;Mon tro om det er flere eksempler på at MS Office har ødelagt for
+offentlig myndighet?&lt;/p&gt;

-&lt;p&gt;Ble nettopp gjort oppmerksom på en
-&lt;a href=&quot;http://www.version2.dk/artikel/13690-breaking-odf-vinder-dokumentformat-krigen &quot;&gt;nyhet fra Version2&lt;/a&gt;
-fra Danmark, der det hevdes at Folketinget har vedtatt at ODF skal
-brukes som dokumentutvekslingsformat i Staten.&lt;/p&gt;
-
-&lt;p&gt;Hyggelig lesning, spesielt hvis det viser seg at de av vedtatt
-kravlisten for hva som skal aksepteres som referert i kommentarfeltet
-til artikkelen og
-&lt;a href=&quot;http://www.version2.dk/artikel/13693-er-ooxml-doemt-ude-her-er-kravene-til-en-offentlig-dokumentstandard&quot;&gt;en
-annen artikkel&lt;/a&gt; i samme nett-avis.  Liker spesielt godt denne:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt; Det skal demonstreres, at standarden i sin helhed kan
-implementeres af alle direkte i sin helhed på flere
-platforme.&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Noe slikt burde være et krav også i Norge.&lt;/p&gt;
+&lt;p&gt;Here is a short update on my &lt;a
+href=&quot;http://people.skolelinux.org/~pere/debian-upgrade-testing/&quot;&gt;my
+Debian Lenny-&gt;Squeeze upgrade testing&lt;/a&gt;.  Here is a summary of the
+difference for Gnome when it is upgraded by apt-get and aptitude.  I&#39;m
+not reporting the status for KDE, because the upgrade crashes when
+aptitude try because of missing conflicts
+(&lt;a href=&quot;http://bugs.debian.org/584861&quot;&gt;#584861&lt;/a&gt; and
+&lt;a href=&quot;http://bugs.debian.org/585716&quot;&gt;#585716&lt;/a&gt;).&lt;/p&gt;
+
+&lt;p&gt;At the end of the upgrade test script, dpkg -l is executed to get a
+complete list of the installed packages.  Based on this I see these
+differences when I did a test run today.  As usual, I do not really
+know what the correct set of packages would be, but thought it best to
+publish the difference.&lt;/p&gt;

-&lt;p&gt;One of the new features in the next Debian/Lenny based release of
-Debian Edu/Skolelinux, which is scheduled for release in the next few
-days, is automatic configuration of the service monitoring system
-Nagios.  The previous release had automatic configuration of trend
-analysis using Munin, and this Lenny based release take that a step
-further.&lt;/p&gt;
-
-&lt;p&gt;When installing a Debian Edu Main-server, it is automatically
-configured as a Munin and Nagios server.  In addition, it is
-configured to be a server for the
-&lt;a href=&quot;http://wiki.debian.org/DebianEdu/HowTo/SiteSummary&quot;&gt;SiteSummary
-system&lt;/a&gt; I have written for use in Debian Edu.  The SiteSummary
-system is inspired by a system used by the University of Oslo where I
-work.  In short, the system provide a centralised collector of
-information about the computers on the network, and a client on each
-computer submitting information to this collector.  This allow for
-automatic information on which packages are installed on each machine,
-which kernel the machines are using, what kind of configuration the
-packages got etc.  This also allow us to automatically generate Munin
-and Nagios configuration.&lt;/p&gt;
-
-&lt;p&gt;All computers reporting to the sitesummary collector with the
-munin-node package installed is automatically enabled as a Munin
-client and graphs from the statistics collected from that machine show
-up automatically on http://www/munin/ on the Main-server.&lt;/p&gt;
-
-&lt;p&gt;All non-laptop computers reporting to the sitesummary collector are
-automatically monitored for network presence (ping and any network
-services detected).  In addition, all computers (also laptops) with
-the nagios-nrpe-server package installed and configured the way
-sitesummary would configure it, are monitored for full disks, software
-raid status, swap free and other checks that need to run locally on
-the machine.&lt;/p&gt;
-
-&lt;p&gt;The result is that the administrator on a school using Debian Edu
-based on Lenny will be able to check the health of his installation
-with one look at the Nagios settings, without having to spend any time
-keeping the Nagios configuration up-to-date.&lt;/p&gt;
-
-&lt;p&gt;The only configuration one need to do to get Nagios up and running
-is to set the password used to get access via HTTP.  The system
-administrator need to run &quot;&lt;tt&gt;htpasswd /etc/nagios3/htpasswd.users
-nagiosadmin&lt;/tt&gt;&quot; to create a nagiosadmin user and set a password for
-it to be able to log into the Nagios web pages.  After that,
-everything is taken care of.&lt;/p&gt;
+&lt;p&gt;For a laptop, centralized user directories and password checking is
+a bit troubling.  Laptops are typically used also when not connected
+to the network, and it is vital for a user to be able to log in or
+unlock the screen saver also when a central server is unavailable.
+This is possible by caching passwords and directory information (user
+and group attributes) locally, and the packages to do so are available
+in Debian.  Here follow two recipes to set this up in Debian/Squeeze.
+It is also possible to set up in Debian/Lenny, but require more manual
+setup there because pam-auth-update is missing in Lenny.&lt;/p&gt;
+
+&lt;h2&gt;LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir&lt;/h2&gt;
+
+This is the traditional method with a twist.  The password caching is
+provided by libpam-ccreds (version 10-4 or later is needed on
+Squeeze), and the directory caching is done by nscd.  The directory
+lookup and password checking is done using LDAP.  If one want to use
+Kerberos for password checking the libpam-ldapd package can be
+replaced with libpam-krb5 or libpam-heimdal.  If one is happy having a
+local home directory with the path listed in LDAP, one can use the
+pam_mkhomedir module from pam-modules to make this happen instead of
+using libpam-mklocaluser.  A setup for pam-auth-update to enable
+pam_mkhomedir will have to be written until a fix for
+&lt;a href=&quot;http://bugs.debian.org/568577&quot;&gt;bug #568577&lt;/a&gt; is in the
+archive.  Because I believe it is a bad idea to have local home
+directories using misleading paths like /site/server/partition/, I
+prefer to create a local user with the home directory in /home/.  This
+is done using the libpam-mklocaluser package.&lt;/p&gt;
+
+&lt;p&gt;These packages need to be installed and configured&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+libnss-ldapd libpam-ldapd nscd libpam-ccreds libpam-mklocaluser
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;The ldapd packages will ask for LDAP connection information, and
+one have to fill in the values that fits ones own site.  Make sure the
+PAM part uses encrypted connections, to make sure the password is not
+sent in clear text to the LDAP server.  I&#39;ve been unable to get TLS
+certificate checking for a self signed certificate working, which make
+LDAP authentication unsafe for Debian Edu (nslcd is not checking if it
+is talking to the correct LDAP server), and very much welcome feedback
+on how to get this working.&lt;/p&gt;
+
+&lt;p&gt;Because nscd do not have a default configuration fit for offline
+caching until &lt;a href=&quot;http://bugs.debian.org/485282&quot;&gt;bug #485282&lt;/a&gt;
+is fixed, this configuration should be used instead of the one
+currently in /etc/nscd.conf.  The changes are in the fields
+reload-count and positive-time-to-live, and is based on the
+instructions I found in the
+&lt;a href=&quot;http://www.flyn.org/laptopldap/&quot;&gt;LDAP for Mobile Laptops&lt;/a&gt;
+instructions by Flyn Computing.&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+       debug-level             0
+       reload-count            unlimited

+       check-files             hosts           yes
+       persistent              hosts           yes
+       shared                  hosts           yes
+       max-db-size             hosts           33554432
+
+       enable-cache            services        yes
+       positive-time-to-live   services        2592000

+       persistent              services        yes

+       max-db-size             services        33554432
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;While we wait for a mechanism to update /etc/nsswitch.conf
+automatically like the one provided in
+&lt;a href=&quot;http://bugs.debian.org/496915&quot;&gt;bug #496915&lt;/a&gt;, the file
+content need to be manually replaced to ensure LDAP is used as the
+directory service on the machine.  /etc/nsswitch.conf should normally
+look like this:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+passwd:         files ldap
+group:          files ldap
+shadow:         files ldap
+hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4
+networks:       files
+protocols:      files
+services:       files
+ethers:         files
+rpc:            files
+netgroup:       files ldap
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;The important parts are that ldap is listed last for passwd, group,
+shadow and netgroup.&lt;/p&gt;
+
+&lt;p&gt;With these changes in place, any user in LDAP will be able to log
+in locally on the machine using for example kdm, get a local home
+directory created and have the password as well as user and group
+attributes cached.
+
+&lt;h2&gt;LDAP/Kerberos + nss-updatedb + libpam-ccreds +
+  libpam-mklocaluser/pam_mkhomedir&lt;/h2&gt;
+
+&lt;p&gt;Because nscd have had its share of problems, and seem to have
+problems doing proper caching, I&#39;ve seen suggestions and recipes to
+use nss-updatedb to copy parts of the LDAP database locally when the
+LDAP database is available.  I have not tested such setup, because I
+discovered sssd.&lt;/p&gt;
+
+&lt;h2&gt;LDAP/Kerberos + sssd + libpam-mklocaluser&lt;/h2&gt;
+
+&lt;p&gt;A more flexible and robust setup than the nscd combination
+mentioned earlier that has shown up recently, is the
+&lt;a href=&quot;https://fedorahosted.org/sssd/&quot;&gt;sssd&lt;/a&gt; package from Redhat.
+It is part of the &lt;a href=&quot;http://www.freeipa.org/&quot;&gt;FreeIPA&lt;/A&gt; project
+to provide a Active Directory like directory service for Linux
+machines.  The sssd system combines the caching of passwords and user
+information into one package, and remove the need for nscd and
+libpam-ccreds.  It support LDAP and Kerberos, but not NIS.  Version
+1.2 do not support netgroups, but it is said that it will support this
+in version 1.5 expected to show up later in 2010.  Because the
+&lt;a href=&quot;http://packages.qa.debian.org/s/sssd.html&quot;&gt;sssd package&lt;/a&gt;
+was missing in Debian, I ended up co-maintaining it with Werner, and
+version 1.2 is now in testing.
+
+&lt;p&gt;These packages need to be installed and configured to get the
+roaming setup I want&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+libpam-sss libnss-sss libpam-mklocaluser
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+The complete setup of sssd is done by editing/creating
+&lt;tt&gt;/etc/sssd/sssd.conf&lt;/tt&gt;.
+
+&lt;blockquote&gt;&lt;pre&gt;
+[sssd]
+config_file_version = 2
+reconnection_retries = 3
+sbus_timeout = 30
+services = nss, pam
+domains = INTERN
+
+[nss]
+filter_groups = root
+filter_users = root
+reconnection_retries = 3
+
+[pam]
+reconnection_retries = 3
+
+[domain/INTERN]
+enumerate = false
+cache_credentials = true
+
+id_provider = ldap
+auth_provider = ldap
+chpass_provider = ldap
+
+ldap_uri = ldap://ldap
+ldap_search_base = dc=skole,dc=skolelinux,dc=no
+ldap_tls_reqcert = never
+ldap_tls_cacert = /etc/ssl/certs/ca-certificates.crt
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;I got the same problem here with certificate checking.  Had to set
+&quot;ldap_tls_reqcert = never&quot; to get it working.&lt;/p&gt;
+
+&lt;p&gt;With the libnss-sss package in testing at the moment, the
+nsswitch.conf file is update automatically, so there is no need to
+modify it manually.&lt;/p&gt;
+
+&lt;p&gt;If you want to help out with implementing this for Debian Edu,
+please contact us on debian-edu@lists.debian.org.&lt;/p&gt;

-&lt;p&gt;Via Slashdot fant jeg en
-&lt;a href=&quot;http://www.cnn.com/2009/OPINION/12/29/schneier.air.travel.security.theater/index.html&quot;&gt;nydelig
-kommentar fra Bruce Schneier&lt;/a&gt; som ble publisert hos CNN i går.  Den
-forklarer forbilledlig hvorfor sikkerhetsteater og innføring av
-totalitære politistatmetoder ikke er løsningen for å gjøre verden
-sikrere.  Anbefales på det varmeste.&lt;/p&gt;
-
-&lt;p&gt;Oppdatering: Kom over
-&lt;a href=&quot;http://gizmodo.com/5435675/president-obama-its-time-to-fire-the-tsa&quot;&gt;nok

-på flyplassene.&lt;/p&gt;
+&lt;p&gt;The last few days I have been looking into the status of the LDAP
+directory in Debian Edu, and in the process I started to miss a GUI
+tool to browse the LDAP tree.  The only one I was able to find in
+Debian/Squeeze and Lenny is
+&lt;a href=&quot;http://luma.sourceforge.net/&quot;&gt;LUMA&lt;/a&gt;, which has proved to
+be a great tool to get a overview of the current LDAP directory
+populated by default in Skolelinux.  Thanks to it, I have been able to
+find empty and obsolete subtrees, misplaced objects and duplicate
+objects.  It will be installed by default in Debian/Squeeze.  If you
+are working with LDAP, give it a go. :)&lt;/p&gt;
+
+&lt;p&gt;I did notice one problem with it I have not had time to report to
+the BTS yet.  There is no .desktop file in the package, so the tool do
+not show up in the Gnome and KDE menus, but only deep down in in the
+Debian submenu in KDE.  I hope that can be fixed before Squeeze is
+released.&lt;/p&gt;
+
+&lt;p&gt;I have not yet been able to get it to modify the tree yet.  I would
+like to move objects and remove subtrees directly in the GUI, but have
+not found a way to do that with LUMA yet.  So in the mean time, I use
+&lt;a href=&quot;http://www.lichteblau.com/ldapvi/&quot;&gt;ldapvi&lt;/a&gt; for that.&lt;/p&gt;
+
+&lt;p&gt;If you have tips on other GUI tools for LDAP that might be useful
+in Debian Edu, please contact us on debian-edu@lists.debian.org.&lt;/p&gt;
+
+&lt;p&gt;Update 2010-06-29: Ross Reedstrom tipped us about the
+&lt;a href=&quot;http://packages.qa.debian.org/g/gq.html&quot;&gt;gq&lt;/a&gt; package as a
+useful GUI alternative.  It seem like a good tool, but is unmaintained
+in Debian and got a RC bug keeping it out of Squeeze.  Unless that
+changes, it will not be an option for Debian Edu based on Squeeze.&lt;/p&gt;

-&lt;p&gt;De færreste er klar over at Skolelinux-prosjektet kom som et resultat
-av en avgjørelse på årsmøtet i
-&lt;a href=&quot;http://www.nuug.no/&quot;&gt;NUUG&lt;/a&gt; i 2000-06-29, der Håkon Wium
-Lie, da varamedlem i styret, tok på seg oppdraget om å starte et
-initiativ kalt &quot;Teach the Teacher&quot;, som skulle være et initiativ for
-å få fri programvare og unix-lignende operativsystemer inn i Skolen.
-Tanken var at en måtte starte med lærerne for at ungene skulle få
-mulighet til å møte en bedre IT-hverdag.  Jeg var tilstede på
-møtet, og hadde sans for ideen, men intet skjedde.  På vårparten
-2001 ble det arrangert en demonstrasjon i anledning at First Tuesday
-hadde invitert Microsoft til et møte for å fortelle om fremtidens
-Internet.  Dette provoserte endel av oss, og EFN og NUUG tok initiativ
-til å arrangere
-&lt;a href=&quot;http://www.digi.no/60982/first-tuesday-mote-med-microsoft-protest&quot;&gt;en
-demonstrasjon utenfor lokalene 2001-05-21&lt;/a&gt;.  Blant de som sto bak
-demonstrasjonen var Vidar Bakke fra NUUG og Håkon W. Lie fra EFN.
-Etter demonstrasjonen arrangerte Håkon en fest hjemme hos seg der alle
-som hadde vært aktive i demonstrasjonsplanlegging og gjennomføringen
-deltok.  Før festen var jeg blitt lei av å vente på at Håkon skulle ta
-initiativ til &quot;Teach the Teacher&quot;, og for å forsøke å få litt fremgang
-besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
-behovet for å hjelpe skolene i gang med bedre datasystemer bestående
-av fri programvare og unix-lignende operativsystemer.  Flere var
-interessert, og Knut Yrvin tenkte på ideen.  Han
-&lt;a href=&quot;http://developer.skolelinux.no/brev/2001-06-28-invitasjon-skolelinux.txt&quot;&gt;ropte
-sammen&lt;/a&gt; til et stiftelsesmøte i prosjektet i sin arbeidsgivers
-Objectwares lokaler ved Ullevål stadion 2001-07-02, og jeg ble med.
-Resten er historie. :)&lt;/p&gt;
+&lt;p&gt;A while back, I
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html&quot;&gt;complained
+about the fact&lt;/a&gt; that it is not possible with the provided schemas
+for storing DNS and DHCP information in LDAP to combine the two sets
+of information into one LDAP object representing a computer.&lt;/p&gt;
+
+&lt;p&gt;In the mean time, I discovered that a simple fix would be to make
+the dhcpHost object class auxiliary, to allow it to be combined with
+the dNSDomain object class, and thus forming one object for one
+computer when storing both DHCP and DNS information in LDAP.&lt;/p&gt;
+
+&lt;p&gt;If I understand this correctly, it is not safe to do this change
+without also changing the assigned number for the object class, and I
+do not know enough about LDAP schema design to do that properly for
+Debian Edu.&lt;/p&gt;
+
+&lt;p&gt;Anyway, for future reference, this is how I believe we could change
+the
+&lt;a href=&quot;http://tools.ietf.org/html/draft-ietf-dhc-ldap-schema-00&quot;&gt;DHCP
+schema&lt;/a&gt; to solve at least part of the problem with the LDAP schemas
+available today from IETF.&lt;/p&gt;

-&lt;p&gt;Endelig har NUUG klart å få kringkastet ut et av sine fordrag på
-TV.  Foredraget om
-&lt;a href=&quot;http://www.nuug.no/aktiviteter/20090512-bifrost/&quot;&gt;utskriftsløsningen
-Biforst&lt;/a&gt; var først ute, pga. at det var det nyeste foredraget som
-var holdt på norsk, og dermed slapp vi å finne ut av hvordan
-teksting av video skulle gjøres.&lt;/p&gt;
-
-&lt;p&gt;NUUG har vært involvert i
-&lt;a href=&quot;http://www.frikanalen.no/&quot;&gt;Frikanalen&lt;/a&gt; en stund nå, for å
-forsøke å få ut budskapet vårt også på TV, og dette første foredraget
-er en sped start på det vi har planlagt.&lt;/p&gt;
-
-&lt;p&gt;NUUGs første foredrag sendes ut via frikanelen på digitalt
-bakkenett, og alle abonnenter av riks-TV skal dermed ha mulighet til å
-ta inn sendingen.  Slå på TVen 5/12 16:05 (for sent), 12/12 14:00,
-19/12 16:00, 24/12 15:37 eller 26/12 16:11 i år, så skal du få se
-meg, Tollef og alle andre de som deltok på møtet på TV.&lt;p&gt;
+&lt;p&gt;A few times I have had the need to simulate the way tasksel
+installs packages during the normal debian-installer run.  Until now,
+I have ended up letting tasksel do the work, with the annoying problem
+of not getting any feedback at all when something fails (like a
+conffile question from dpkg or a download that fails), using code like
+this:
+
+&lt;blockquote&gt;&lt;pre&gt;
+export DEBIAN_FRONTEND=noninteractive
+tasksel --new-install
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+This would invoke tasksel, let its automatic task selection pick the
+tasks to install, and continue to install the requested tasks without
+any output what so ever.
+
+Recently I revisited this problem while working on the automatic
+package upgrade testing, because tasksel would some times hang without
+any useful feedback, and I want to see what is going on when it
+happen.  Then it occured to me, I can parse the output from tasksel
+when asked to run in test mode, and use that aptitude command line
+printed by tasksel then to simulate the tasksel run.  I ended up using
+code like this:
+
+&lt;blockquote&gt;&lt;pre&gt;
+export DEBIAN_FRONTEND=noninteractive
+cmd=&quot;$(in_target tasksel -t --new-install | sed &#39;s/debconf-apt-progress -- //&#39;)&quot;
+$cmd
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;The content of $cmd is typically something like &quot;&lt;tt&gt;aptitude -q
+--without-recommends -o APT::Install-Recommends=no -y install
+~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired
+~pimportant&lt;/tt&gt;&quot;, which will install the gnome desktop task, the
+laptop task and all packages with priority standard , required and
+important, just like tasksel would have done it during
+installation.&lt;/p&gt;
+
+&lt;p&gt;A better approach is probably to extend tasksel to be able to
+install packages without using debconf-apt-progress, for use cases
+like this.&lt;/p&gt;

-&lt;p&gt;Dagens
-&lt;a href=&quot;http://www.statkart.no/Gratis+karttjenester.d25-SwJfY1-.ips&quot;&gt;kartnyhet&lt;/a&gt;
-er at kartverket gir ikke-kommersiell tilgang til
-en WMS-tjeneste der en til privat bruk kan hente ut bilder av
-kartutsnitt så lenge disse ikke lagres lokalt, brukes i begrenset
-oppløsning og ikke skader kartverket og rettighetshavernes omdømme og
-interesse.&lt;/p&gt;
-
-&lt;p&gt;I går publiserte Ivan Sanchez
-&lt;a href=&quot;http://www.opengeodata.org/2009/11/11/921/&quot;&gt;kaketesten&lt;/a&gt;
-som et forslag til en (av forhåpentligvis flere) måter å teste om kart
-eller kartdata er fritt tilgjengelige på.  Testen er enkel, og sier
-enkelt (oversatt av meg): Et sett med geodata, eller en kart, er kun
-fritt tilgjengelig hvis noen kan gi deg en kake med det kartet på
-toppen, som en gave.  Kartverkets publisering av kart feiler så vidt
-jeg kan se denne testen fullstendig.  En kan slik jeg leser vilkårene
-ikke be en konditor om å lage en kake (brudd på kravet om
-ikke-kommersiell bruk) med kartverkets kart.&lt;/p&gt;
-
-&lt;p&gt;De som vil lage karttjenester basert på denne nye tjenesten fra
-kartverket vil gjøre det på kartverkets nåde og med sterke bindinger
-og begresninger.  Det blir dermed helt uinteressant for meg.  Jeg vil
-nok fortsette å bruke data fra
-&lt;a href=&quot;http://www.openstreetmap.org&quot;&gt;OpenStreetmap.org&lt;/a&gt;, der jeg
-har kontrollen med tilgang til kartdataene, og kan endre på de
-underliggende dataene som jeg ønsker.&lt;/p&gt;
-
-&lt;p&gt;Som et eksempel, så trenger vi til en norsk
-&lt;a href=&quot;http://www.fixmystreet.com/&quot;&gt;FixMyStreet-installasjon&lt;/a&gt;
-tilgang til vektorutgaven av kommunegrensene.  Denne nye karttjenesten
-er ubrukelig til dette.&lt;/p&gt;
+&lt;p&gt;&lt;a href=&quot;http://www.dagbladet.no/2010/06/16/nyheter/innenriks/streik/arbeidsliv/12157858/&quot;&gt;Dagbladet
+melder&lt;/a&gt; at Vinmonopolet med bakgrunn i vekterstreiken som pågår i
+Norge for tiden, har bestemt seg for med vitende og vilje å bryte
+sentralbanklovens paragraf 14 ved å nekte folk å betale med
+kontanter, og at flere butikker planlegger å følge deres eksempel.
+Jeg synes det er hårreisende hvis de slipper unna med et slikt
+soleklart lovbrudd, og lurer på hva slags muligheter jeg vil ha hvis
+jeg blir nektet å handle med kontanter.  Jeg handler i hovedsak med
+kontanter selv, da jeg anser det som en borgerrett å kunne handle
+anonymt uten at det blir registrert.  For meg er det et angrep på mitt
+personvern å nekte å ta imot kontant betaling.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://www.lovdata.no/all/tl-19850524-028-003.html#14&quot;&gt;Paragrafen
+i sentralbankloven&lt;/a&gt; lyder:&lt;/p&gt;
+
+&lt;blockquote&gt;
+&lt;p&gt;§ 14. Tvungent betalingsmiddel&lt;/p&gt;
+
+&lt;p&gt;Bankens sedler og mynter er tvungent betalingsmiddel i Norge. Ingen
+er pliktig til i én betaling å ta imot mer enn femogtyve mynter av
+hver enhet.&lt;/p&gt;
+
+&lt;p&gt;Sterkt skadde sedler og mynter er ikke tvungent
+betalingsmiddel. Banken gir nærmere forskrifter om erstatning for
+bortkomne, brente eller skadde sedler og mynter.&lt;/p&gt;
+
+&lt;p&gt;Selv om en avtale inneholder klausul om betaling av en
+pengeforpliktelse i gullverdi, kan skyldneren frigjøre seg med tvungne
+betalingsmidler uten hensyn til denne klausul.&lt;/p&gt;
+&lt;/blockquote&gt;
+
+&lt;p&gt;Det er med bakgrunn i denne lovet ikke tillatt å nekte å ta imot
+kontakt betaling.  Det er en lov jeg har sans for, og som jeg mener må
+håndheves strengt.&lt;/p&gt;

-&lt;p&gt;Det er svært gledelig å se at
-&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3360796.ece&quot;&gt;retten
-fant at Telenor ikke skal fungere som Internet-voktere&lt;/a&gt; på vegne av
-opphavsrettsmafiaen.  TONO påstår ikke overraskende &quot;rettighetshaverne
-er rettsløse&quot;.  De burde jo vite alt om hvordan rettighetshaverne blir
-behandlet, som har
-&lt;a href=&quot;http://www.ballade.no/nmi.nsf/doc/art2009042008430427192492&quot;&gt;nektet
-å hjelpe et av sine medlemmer i en plagiatsak&lt;/a&gt; mot Universal i
-Polen.&lt;/p&gt;
-
-&lt;p&gt;Ved opphavsrettsbrudd så er det jo den som offentliggjort
-kulturuttrykk ulovlig som må stilles til ansvar, og ikke noen andre.
-Hverken Telenor eller Pirate Bay publiserer innholdet.  Telenor lager
-en Internet-tjeneste som brukes av borgerne til sitt daglige virke,
-det være seg å holde kontakt med barnebarn, skaffe medisinsk viten
-eller holde seg orientert i samfunnsdebatten.  Det bør de gjøre uten å
-tvinges til å være overvåkningsinstans.  Og Pirate Bay lager en
-katalog over hvor lovlig og ulovlig innhold på Internet er å få tak i.
-De publiserer ikke innholdet, de lager kun en katalog over det.  Hvis
-en ikke liker det som blir publisert, så må det tas opp med den som
-publiserer, ikke noen andre.&lt;/p&gt;
-
-&lt;p&gt;Personlig velger jeg å stort sett bruke kulturuttrykk som
-publiseres med mer brukervennlige vilkår, som CC-BY og lignende.&lt;/p&gt;
+&lt;p&gt;For those of us caring about document exchange and
+interoperability, &lt;a href=&quot;http://www.officeshots.org/&quot;&gt;OfficeShots&lt;/a&gt;
+is a great service.  It is to ODF documents what
+&lt;a href=&quot;http://browsershots.org/&quot;&gt;BrowserShots&lt;/a&gt; is for web
+pages.&lt;/p&gt;
+
+&lt;p&gt;A while back, I was contacted by Knut Yrvin at the part of Nokia
+that used to be Trolltech, who wanted to help the OfficeShots project
+and wondered if the University of Oslo where I work would be
+interested in supporting the project.  I helped him to navigate his
+request to the right people at work, and his request was answered with
+a spot in the machine room with power and network connected, and Knut
+arranged funding for a machine to fill the spot.  The machine is
+administrated by the OfficeShots people, so I do not have daily
+contact with its progress, and thus from time to time check back to
+see how the project is doing.&lt;/p&gt;
+
+&lt;p&gt;Today I had a look, and was happy to see that the Dell box in our
+machine room now is the host for several virtual machines running as
+OfficeShots factories, and the project is able to render ODF documents
+in 17 different document processing implementation on Linux and
+Windows.  This is great.&lt;/p&gt;
