How to add extra storage servers in Debian Edu / Skolelinux
+
Freedombox on Dreamplug, Raspberry Pi and virtual x86 machine
14th March 2014
+

The Freedombox +project is working on providing the software and hardware for +making it easy for non-technical people to host their data and +communication at home, and being able to communicate with their +friends and family encrypted and away from prying eyes. It has been +going on for a while, and is slowly progressing towards a new test +release (0.2).

+ +

And what day could be better than the Pi day to announce that the +new version will provide "hard drive" / SD card / USB stick images for +Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization +system), and can also be installed using a Debian installer preseed +file. The Debian based Freedombox is now based on Debian Jessie, +where most of the needed packages used are already present. Only one, +the freedombox-setup package, is missing. To try to build your own +boot image to test the current status, fetch the freedom-maker scripts +and build using +vmdebootstrap +with a user with sudo access to become root: + +

+git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
+  freedom-maker
+sudo apt-get install git vmdebootstrap mercurial python-docutils \
+  mktorrent extlinux virtualbox qemu-user-static binfmt-support \
+  u-boot-tools
+make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
+
+ +

Root access is needed to run debootstrap and mount loopback +devices. See the README for more details on the build. If you do not +want all three images, trim the make line. But note that thanks to a race condition in +vmdebootstrap, the build might fail without the patch to the +kpartx call.

+ +

If you instead want to install using a Debian CD and the preseed +method, boot a Debian Wheezy ISO and use this boot argument to load +the preseed values:

+ +
+url=http://www.reinholdtsen.name/freedombox/preseed-jessie.dat
+
+ +

But note that due to a +recently introduced bug in apt in Jessie, the installer will +currently hang while setting up APT sources. Killing the +'apt-cdrom ident' process when it hang a few times during the +installation will get the installation going. This affect all +installations in Jessie, and I expect it will be fixed soon.

+ +Give it a go and let us know how it goes on the mailing list, and help +us get the new release published. :) Please join us on +IRC (#freedombox on +irc.debian.org) and +the +mailing list if you want to help make this vision come true.

How to add extra storage servers in Debian Edu / Skolelinux

12th March 2014

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 Debian Edu / Skolelinux, 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 Skolelinux Drift AS, -where I am on the board of directors, asked about how to do this. The -steps to get this working are the following:

It has been a while since I managed to publish the last interview, -but the Debian Edu / -Skolelinux community is still going strong, and yesterday we even -had a new school administrator show up on -#debian-edu to share -his success story with installing Debian Edu at their school. This -time I have been able to get some helpful comments from the creator of -Knoppix, Klaus Knopper, who was involved in a Skolelinux project in -Germany a few years ago.

- -

Who are you, and how do you spend your days?

- -

I am Klaus Knopper. I have a master degree in electrical -engineering, and is currently professor in information management at -the university of applied sciences Kaiserslautern / Germany and -freelance Open Source software developer and consultant.

- -

All of this is pretty much of the work I spend my days with. Apart -from teaching, I'm also conducting some more or less experimental -projects like the Knoppix GNU/Linux live -system (Debian-based like Skolelinux), -ADRIANE -(a blind-friendly talking desktop system) and -LINBO -(Linux-based network boot console, a fast remote install and repair -system supporting various operating systems).

- -

How did you get in contact with the Skolelinux / Debian Edu -project?

- -

The credit for this have to go to Kurt Gramlich, who is the German -coordinator for Skolelinux. We were looking for an all-in-one open -source community-supported distribution for schools, and Kurt -introduced us to Skolelinux for this purpose.

- -

What do you see as the advantages of Skolelinux / Debian -Edu?

- -
    -
  • Quick installation,
  • -
  • works (almost) out of the box,
  • -
  • contains many useful software packages for teaching and learning,
  • -
  • is a purely community-based distro and not controlled by a - single company,
  • -
  • has a large number of supporters and teachers who share their - experience and problem solutions.
  • -
- -

What do you see as the disadvantages of Skolelinux / Debian -Edu?

- -
    -
  • Skolelinux is - as we had to learn - not easily upgradable to - the next version. Opposed to its genuine Debian base, upgrading to - a new version means a full new installation from scratch to get it - working again reliably. - -
  • Skolelinux is based on Debian/stable, and therefore always a - little outdated in terms of program versions compared to Edubuntu or - similar educational Linux distros, which rather use Debian/testing - as their base. - -
  • Skolelinux has some very self-opinionated and stubborn default - configuration which in my opinion adds unnecessary complexity and is - not always suitable for a schools needs, the preset network - configuration is actually a core definition feature of Skolelinux - and not easy to change, so schools sometimes have to change their - network configuration to make it "Skolelinux-compatible". - -
  • Some proposed extensions, which were made available as - contribution, like secure examination mode and lecture material - distribution and collection, were not accepted into the mainline - Skolelinux development and are now not easy to maintain in the - future because of Skolelinux somewhat undeterministic update - schemes.
  • - -
  • Skolelinux has only a very tiny number of base developers - compared to Debian.
  • - -
- -

For these reasons and experience from our project, I would now -rather consider using plain Debian for schools next time, until -Skolelinux is more closely integrated into Debian and becomes -upgradeable without reinstallation.

- -

Which free software do you use daily?

- -

GNU/Linux with LXDE desktop, bash for interactive dialog and -programming, texlive for documentation and correspondence, -occasionally LibreOffice for document format conversion. Various -programming languages for teaching.

- -

Which strategy do you believe is the right one to use to -get schools to use free software?

- -

Strong arguments are

- -
    - -
  • Knowledge is free, and so should be methods and tools for - teaching and learning.
  • - -
  • Students can learn with and use the same software at school, at - home, and at their working place without running into license or - conversion problems.
  • - -
  • Closed source or proprietary software hides knowledge rather - than exposing it, and proprietary software vendors try to bind - customers to certain products. But teachers need to teach - science, not products.
  • - -
  • If you have everything you for daily work as open source, what - would you need proprietary software for?
