- <div class="date">10th November 2014</div>
- <div class="body"><p>The right to communicate with your friends and family in private,
-without anyone snooping, is a right every citicen have in a liberal
-democracy. 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>

-About Debian Edu and Skolelinux
-===============================
-
-Debian Edu, also known as Skolelinux[2], is a Linux distribution based
-on Debian providing an out-of-the box environment of a completely
-configured school network. Immediately after installation a school
-server running all services needed for a school network is set up just
-waiting for users and machines being added via GOsa², a comfortable
-Web-UI. A netbooting environment is prepared using PXE, so after
-initial installation of the main server from CD or USB stick all other
-machines can be installed via the network. The provided school server
-provides LDAP database and Kerberos authentication service,
-centralized home directories, DHCP server, web proxy and many other
-services. The desktop contains more than 60 educational software
-packages[3] and more are available from the Debian archive, and
-schools can choose between KDE, Gnome, LXDE, Xfce and MATE desktop
-environment.

- <div class="date">23rd October 2014</div>
- <div class="body"><p>I spent last weekend at <a href="http://www.makercon.no/">Makercon
-Nordic</a>, a great conference and workshop for makers in Norway and
-the surrounding countries. I had volunteered on behalf of the
-Norwegian Unix Users Group (NUUG) to video record the talks, and we
-had a great and exhausting time recording the entire day, two days in
-a row. There were only two of us, Hans-Petter and me, and we used the
-regular video equipment for NUUG, with a
-<a href="http://dvswitch.alioth.debian.org/wiki/">dvswitch</a>, a
-camera and a VGA to DV convert box, and mixed video and slides
-live.</p>
-
-<p>Hans-Petter did the post-processing, consisting of uploading the
-around 180 GiB of raw video to Youtube, and the result is
-<a href="https://www.youtube.com/user/MakerConNordic/">now becoming
-public</a> on the MakerConNordic account. The videos have the license
-NUUG always use on our recordings, which is
-<a href="http://creativecommons.org/licenses/by-sa/3.0/no/">Creative
-Commons Navngivelse-Del på samme vilkår 3.0 Norge</a>. Many great
-talks available. Check it out! :)</p>
