Identity Management und 2FA mit (Free)IPA @Chemnitzer Linuxtage 2015

My first post in German, publishing the Slide Deck (in German) for my presentation about IPA and 2FA held at Chemnitzer Linux days 2015.

Mein erster Post in Deutsch. Hier die Slides von meinem Vortrag an den Chemnitzer Linux Tagen 2015.

Abstract:
IPA ist ein Identity Management System für Linux und Unix, das stetig an Bedeutung gewinnt. Mittlerweile ist es des öfteren in Behörden, Banken, Versicherungen, aber auch in KMUs im Einsatz. IPA kann man sich als «Active Directory» für Linux vorstellen. IPA verheiratet LDAP und Kerberos zu einem Opensource Produkt das leicht zu installieren und zu unterhalten ist. Mit IPA kann dank Kerberos Single-Sign-On realiert werden (Authentifizierung). Regelsätze legen fest, welche Benutzer von welchen Benutzergruppen auf welche Services und Hosts zugreifen dürfen.

Seit einiger Zeit lassen sich mit IPA auch sehr einfach 2FA-Lösungen (Zwei-Faktor-Autentifizierung) realisieren, um die Sicherheit weiter zu erhöhen.

Das Slide Deck gibt es hier:

Slides vom Vortrag

Die Slides habe ich übringens bei einem Spontanvortrag bei der Berliner Linux User Group am 2015-04-08 wiederverwendet. Aufgrund des Feedbacks wird in den nächsten Wochen ein ca. 4h Workshop an einem Samstag organisiert.

Ich hoffe es hat allen anwesenden Spass gemacht und konnte Euch etwas Wissen vermitteln. Feedback zu beiden Anlässen willkommen.

FUDCon 2012 Kuala Lumpur, Malaysia

FUDCon 2012 Kuala Lumpur

FUDCon 2012 Kuala Lumpur

Since I’ll be in Kuala Lumpur anyway, I take the chance to visit the upcoming FUDcon (Fedora User and Developer Conference) which will take place May 18th to 20th at the Asia Pacific University College of Technology & Innovation. I dont know yet if I can be there all three days, but at least days 2 and 3.

I’m really glad to meet the Fedora people from another continent. I’ve been visiting Malaysia back in 2009, it is a very beautiful country with nice people. So this time my visit is different, combining vacation and some nice Linux stuff.

Looking at the list of talks, it will be interessting to join those sessions. Unfortunately it is too late for me to prepare a talk. The only thing I miss is the annoucement of a social event, maybe I have overseen it?

See you there… Have fun!

Retrospection to FOSDEM 2012 Brussels, Belgium

This year I made it, It was my first time at FOSDEM, the Free and Open Source Developers European Meeting. I was amazed about the crowd of people and the amount of talks. It was simply impossible to visit all interesting lectures, because lots of them has been held in parallel.

It was also a pleasure to meet again all those people I know from the open source communities. The Friday beer event was very nice, as well as chatting with people between and after the lectures.

From my pint of view, the most important talks have been the inside views to oVirt and the presentations about the Deltacloud project. It was also important to get more informations about Aeolus . Most of the for me important talks are bound to cloud and/or virtualization projects. This is because I’ll hit those project sooner or later on my job as Linux consultant.

Lessons learned
I’ll try to get to Fosdem 2013 if time allows. But next time I’ll be better prepared for the inconveniences of the venue.

  • If the weather will be the same as this year, three layers of clothes are not enough, in some auditoriums the temperatures have been close to the freezing point.
  • If it is heavily snowing, touch screens of smart phones are going berserk, navigation not possible, taking a old style navigation device with me as well a paper city-map
  • If you wait for the bus, you need to wave hands if the bus approaches or it will simply pass you and letting you wait for another 20 min at -15°C
  • Having a hotel near “Gare Central” is a big plus, it is near the Delirium Cafe where the Friday beer event happens as well as on the route of Bus Nr. 71 to ULB
  • SMS messages in Belgium obviously have usually a delay of a few hours and are not reliable, calling friends costs much more but does the job
  • Mobile internet access is not always reliable in Belgium, since I dont know the city very well, I’ll take a off-line navigation Phone with me (my old Nokia E72)

A huge thank you
I would like to thank all the volunteers who organized the event and made it an unforgettable event, as well as the countless speakers sharing their knowledge with the world

Upcoming events
The next upcoming interesting events in Europe:

  • Chemnitzer Linux-Tage 2012 March 17th and 18th
  • LinuxTag 2012 in Berlin (my new home town) May 23th to May 26th.

If I missed an event to mention here, let me know.

Have fun!

FUDCon and FrOSCamp Day Two

After the official party called “wired dreams” @StuZ on Friday, I was a bit late and arrived @ETH in the early afternoon.

At 14:00 there was the (from my point of view) probably best workshop, it was about Puppet. Puppet is an open source data center automation and configuration management tool. For more information see http://www.puppetlabs.com/.

There is also a Swiss Puppet User Group. It seems to mostly active in western Switzerland.

The second interesting talk was about collectd, a system performance statistics gathering tool similar to Cacti, but more sophisticated.

Conclusion: The two days at FUDCon and FrOSCamp have been really worth to attend. Not only because of the talks, but also for socializing with other people. I had the chance to talk with people from the Fedora Project as well as to some Red Hat people.

Unfortunately FUDCon will not be held in Switzerland for the next few years, because the conference will always be hold in another country each year. I hope similar conferences will be held in Switzerland (or at least in nearby regions) in the next few months.

Have fun!
