+ <description><p>For 12 år siden, skrev jeg et lite notat om
+<a href="http://i18n.skolelinux.no/localekoder.txt">bruk av språkkoder
+i Norge</a>. Jeg ble nettopp minnet på dette da jeg fikk spørsmål om
+notatet fortsatt var aktuelt, og tenkte det var greit å repetere hva
+som fortsatt gjelder. Det jeg skrev da er fortsatt like aktuelt.</p>
+
+<p>Når en velger språk i programmer på unix, så velger en blant mange
+språkkoder. For språk i Norge anbefales følgende språkkoder (anbefalt
+locale i parantes):</p>
+
+<p><dl>
+<dt>nb (nb_NO)</dt><dd>Bokmål i Norge</dd>
+<dt>nn (nn_NO)</dt><dd>Nynorsk i Norge</dd>
+<dt>se (se_NO)</dt><dd>Nordsamisk i Norge</dd>
+</dl></p>
+
+<p>Alle programmer som bruker andre koder bør endres.</p>
+
+<p>Språkkoden bør brukes når .po-filer navngis og installeres. Dette
+er ikke det samme som locale-koden. For Norsk Bokmål, så bør filene
+være navngitt nb.po, mens locale (LANG) bør være nb_NO.</p>
+
+<p>Hvis vi ikke får standardisert de kodene i alle programmene med
+norske oversettelser, så er det umulig å gi LANG-variablen ett innhold
+som fungerer for alle programmer.</p>
+
+<p>Språkkodene er de offisielle kodene fra ISO 639, og bruken av dem i
+forbindelse med POSIX localer er standardisert i RFC 3066 og ISO
+15897. Denne anbefalingen er i tråd med de angitte standardene.</p>
+
+<p>Følgende koder er eller har vært i bruk som locale-verdier for
+"norske" språk. Disse bør unngås, og erstattes når de oppdages:</p>
+
+<p><table>
+<tr><td>norwegian</td><td>-> nb_NO</td></tr>
+<tr><td>bokmål </td><td>-> nb_NO</td></tr>
+<tr><td>bokmal </td><td>-> nb_NO</td></tr>
+<tr><td>nynorsk </td><td>-> nn_NO</td></tr>
+<tr><td>no </td><td>-> nb_NO</td></tr>
+<tr><td>no_NO </td><td>-> nb_NO</td></tr>
+<tr><td>no_NY </td><td>-> nn_NO</td></tr>
+<tr><td>sme_NO </td><td>-> se_NO</td></tr>
+</table></p>
+
+<p>Merk at når det gjelder de samiske språkene, at se_NO i praksis
+henviser til nordsamisk i Norge, mens f.eks. smj_NO henviser til
+lulesamisk. Dette notatet er dog ikke ment å gi råd rundt samiske
+språkkoder, der gjør

<description><p>For a while now, I have been looking for a sensible offsite backup
solution for use at home. My requirements are simple, it must be
cheap and locally encrypted (in other words, I keep the encryption
keys, the storage provider do not have access to my private files).

+One idea me and my friends had many years ago, before the cloud
+storage providers showed up, was to use Google mail as storage,
writing a Linux block device storing blocks as emails in the mail
service provided by Google, and thus get heaps of free space. On top
of this one can add encryption, RAID and volume management to have
install s3ql</tt>. Next, pick a storage provider. I ended up picking
Greenqloud, after reading their nice recipe on

<p>The file content is uploaded when the cache is full, while the

file system content is flushed to the cloud, one can either umount the

- <title>How to add extra storage servers in Debian Edu / Skolelinux</title>

- <description><p>On larger sites, it is useful to use a dedicated storage server for
-storing user home directories and data. The design for handling this
-in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is
-to update the automount rules in LDAP and let the automount daemon on
-the clients take care of the rest. I was reminded about the need to
-document this better when one of the customers of
-<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am
-on the board of directors, asked about how to do this. The steps to
-get this working are the following:</p>
-
-<p><ol>
-
-<li>Add new storage server in DNS. I use nas-server.intern as the
-example host here.</li>
-
-<li>Add automoun LDAP information about this server in LDAP, to allow
-all clients to automatically mount it on reqeust.</li>
-
-<li>Add the relevant entries in tjener.intern:/etc/fstab, because
-tjener.intern do not use automount to avoid mounting loops.</li>
-
-</ol></p>
-
-<p>DNS entries are added in GOsa², and not described here. Follow the
-<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions
-in the manual</a> (Machine Management with GOsa² in section Getting
-started).</p>
-
-<p>Ensure that the NFS export points on the server are exported to the
-relevant subnets or machines:</p>
-
-<p><blockquote><pre>
-root@tjener:~# showmount -e nas-server
-Export list for nas-server:
-/storage 10.0.0.0/8
-root@tjener:~#
-</pre></blockquote></p>
-
-<p>Here everything on the backbone network is granted access to the
-/storage export. With NFSv3 it is slightly better to limit it to
-netgroup membership or single IP addresses to have some limits on the
-NFS access.</p>
-
-<p>The next step is to update LDAP. This can not be done using GOsa²,
-because it lack a module for automount. Instead, use ldapvi and add
-the required LDAP objects using an editor.</p>
-
-<p><blockquote><pre>
-ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
-</pre></blockquote></p>
-
-<p>When the editor show up, add the following LDAP objects at the
-bottom of the document. The "/&" part in the last LDAP object is a
-wild card matching everything the nas-server exports, removing the
-need to list individual mount points in LDAP.</p>
-
-<p><blockquote><pre>
-add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
-objectClass: automount
-cn: nas-server
-automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
-
-add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
-objectClass: top
-objectClass: automountMap
-ou: auto.nas-server
-
-add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
-objectClass: automount
-cn: /
-automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
-</pre></blockquote></p>
-
-<p>The last step to remember is to mount the relevant mount points in
-tjener.intern by adding them to /etc/fstab, creating the mount
-directories using mkdir and running "mount -a" to mount them.</p>
-
-<p>When this is done, your users should be able to access the files on
-the storage server directly by just visiting the
-/tjener/nas-server/storage/ directory using any application on any
-workstation, LTSP client or LTSP server.</p>
