First patchlevel release Univention Corporate Server 4.0-1

The first patchlevel release of UCS 4 has been released pooling more than 80 errata updates since UCS' last major release in November 2014


  • Update of the UCS basis through the integration of the Debian "Wheezy" 7.8 point update
  • Simplification of the UCS system setup
  • Improvements of the integrated tool "Active Directory Connection": This tool is perfect for everyone who wants to extend an existing Windows server environment with additional Enterprise applications via the Univention App Center. For example, groupware solutions such as OX App Suite or Zarafa which are installed via the Univention App Center can thus be managed via Microsoft Active Directory including all existing user identities.
  • Simplification of UCS cloud setups: Cloud setup information from cloud service providers is now directly transmitted to UCS. Thus, cloud service providers can provide their customers with a pre-configured and ready-to start UCS-based cloud installation.

Upgrade of "free for personal use" license of Univention Corporate Server 4.0

From now on, UCS users who are using the “free for personal use” license for private purposes can extend the number of administrated users and clients in one UCS domain to 50 each. Beforehand, the number was limited to 5 users and 5 clients per license.

With this upgrade, users can much better exploit UCS’ potential for IT administration. Users who already use a “free for personal use” license, can order the upgrade simply by requesting it via Univention's contact form.

Fedora 21 VS Ubuntu 14.10 ( performance /User experience)

Hi Linuxites, 

would like to share my recent observations between Fedora 21 ( just released ) vs UBuntu 14.10. 

Configuration of my machine :: SONY VAIO VPCEB1E03, core i3 ( 1st generation), 8GB ram, 320gb HDD,

Background :: Just one week back installed Ubuntu 14.0 on my laptop by erasing windows 7.  Impressed with the  look and feel of Ubuntu, within few minutes able to use it.  Today installed fedora 21 official release on the same m/c by erasing Ubuntu 14.10.  My observations are like the following.  Just trying to settle down whether i have to go with UBuntu way or fedora way (?) .  Lets see what i have decided!!

Performance / User experience  ( UBuntu 14.10 vs Fedora 21-5 official release )

Ubuntu 14.10::

Looks impressive, Terminal window is beautifully coloured, graphics are good, heavy weight icons Seems, everything is OK, graphics drivers are installed no  issues.  But, I am facing few problems, like fan control always my FAN is running very fast and making noise, RAM is eaten up around 1.8 to 2.2 GB.  Started rhythm box music player, after playing sometime closed it. Executed top command, and it is showing still music player is running and utilizing CPU (??), I have to manually shut down the player.   Now, coming to application search box , when I type from keyboard my letters are being displayed very slowly, applications display is very very slow at this moment, my FAN makes so much noise.  Disabled web searching options in the settings, still i have same issues.  Software updates are installed without any issues.  GCC 4.9.1 is working fine.  kernel 3.16.x

Fedora 21-5 ( Official release ) ::

Instsalled, compared to Ubuntu installation seems this is fast.  everything is fine.  Now, repeated same actions from GNOME window manager.  graphics drivers are installed no issues.  surprisingly regarding FAN control, my fan is so silent and it is not making any noise, so so so quiet.  RAM is around 780MB is eaten up when I opened firefox, rhythm box music player and few terminals.  it was never above 1 GB.. thats impressive(same applications were opened with Ubuntu 14.10 also, it was RAM hungry 1.8 GB to 2.2GB).  applications are closed and immediately disappeared from my TOP command menu.  The surprising and I like very much is application search box.... Unlike in UBuntu Unity desktop search option, the Fedora 21 search is very fast , display is very fast, text input is very fast, i have tested really half an hour and seems, everything is awesome. FAN is not making any noise very quiet.  I havent even disabled web searching.  Software upadtes are installed without any issue.  Well, one awkward situation with fedora 21 is without using GNOME TWEAK TOOL, i cannot get my minimize and maximize buttons in terminal.  Fedora terminal windows are good,  but compared to Ubuntu terminals they are less attractivre. GCC 4.9.2 is working fine.  Kernel is 3.17.x

Conclusion :

I am a computer engineering graduate and software architect.  I thought i will stick to UBuntu because of its impressive looks.  But, due its resource hungry nature  and slow response times from desktop point of view, I think i will stick to FEDORA 21.  btw, I have two more laptops which run REDHAT ENTERPRISE LINUX 7.0 and SUSE ENTERPRISE LINUX 12.0 commercial versions, using core i7 and core i5 respectively .  RHEL 7.0 is more impressive from user experience point of view compared to all others.  

UBuntu applications and Fedora 21 applications are almost all are same.  Same packages, same utilities, i think I can do everything with both the versions from LINUX POINT OF VIEW. 

If UBUntu improves its response times with its window manager Unity , then it will become a great desktop compared to other versions.  Seems, UBuntu team is concentrating only on good looks without bothering about response times.  Their  team should concentrate on improving  response times. 

For the moment next 6 months, i will stick with fedora 21 only, Lets see what UBuntu 15.04 will come up with an answer to Fedora 21.

UCS 4.0 will be released in November. The second milestone, released last week, already includes the completely redesigned and restructured Univention Management Console (UMC).

People who are interested in finding out more about the new design and the motives behind it, are invited to read the article from Alexander Kläser, product developer at Univention, who explains it all in there.

The second milestone of UCS 4.0 is available to download for anyone and feedback for the improvement of this next major release is more than welcome.


Second milestone of Univention Corporate Server 4.0

Today, Univention has released the second milestone of Univention Corporate Server 4.0. This is aimed at channel partners, technology partners and interested parties, who want to take a first glance at the upcoming release of Univention Corporate Server (UCS), which is planned for mid of November 2014.

New computing centers for Afghanistan with UCS

The center for international and intercultural communication (ZiiK) at the Technical University Berlin (TU) is dedicated to offering students from developing countries long-term perspectives focussing hereby on sustainable help in information technology.

Since 2002, Dr. Nazir Peroz, born in Afghanistan and Director of the Ziik, supervised the setup of new IT centers in five Afghan universities with the use of open source software. “From the beginning, our aim was always to create something that will continue to help Afghanistan in the long term as well, something which opens up perspectives for the future for the nation, and offers the people hope”, explained Peroz. “The IT sector is ideal for achieving these goals because it is indispensable for modern economy on the one hand and requires lower investments in hardware than other branches of trade on the other.”

When the team arrived in Kabul first in 2002, the situation was dreadful. After decades of war and the tyranny of the Taliban, there was not much of the academic education system left. In the whole of the capital’s college there were just a handful of old computers, some of which didn’t even work anymore. When establishing the computer centers, the Germano-Afghan project employed Open Source software right from the start. “Naturally, the license costs were the most important reason for choosing Open Source software”, said Daniel Tippmann, Project Planner and Coordinator at the ZiiK.

As to the operating system to use, the team wanted a system, which puts the Afghan staff in a position to perform all the necessary work with as little training as possible and if possible without our support. Over the years, the ZiiK team and its Afghan partners tried out numerous different operating systems, primarily different Linux distributions. The youngest of the computer centers, the IT Center Kandahar (ITCQ), was the first to set up all the servers on the basis of Univention Corporate Server (UCS), which proved to be the best for them in terms of ease of use, flexibility and scope of action due to its App Center, which offers the installation and integration of numerous other proven open source solutions. Until the end of 2015, the other four universities will follow and migrate completely to UCS.

Patch level release Univention Corporate Server 3.2-3

The latest patch level release UCS 3.2-3 includes all errata updates and an update to Linux kernel version 3.10.11 which involves many bug fixes and improves the hardware support.

Special highlight is the new module "Active Directory Connection", which replaces the previous AD connector for mounting a UCS installation in an AD domain. UCS users can now not only migrate an existing Microsoft server system to UCS but also configure their UCS system as part of an existing AD domain, for example to use UCS as the platform for applications from independent third-party solutions via the Univention App Center. Further highlights are a completely revised system setup wizard, a backport of PHP 5.4.4 and improved replication between OpenLDAP and Samba 4.
