paedML

from Wikipedia, the free encyclopedia

paedML is a preconfigured network solution that was specially developed for the requirements in schools in the state of Baden-Württemberg. The model solution is used in the educational computer networks of the individual schools.

The sample solution is available as a complete package for the network operating systems Windows , Linux and Novell . Since September 2003, the support network of the State Media Center Baden-Württemberg has been responsible for development, school network advice and technical support.

Functionality

The sample solution takes into account user-friendly installation, support and maintenance. So it can be installed by specialists with relatively little effort. All network services that are to be used in the school are already set up after installation. A particular preference is the Sheila principle ( S ven healing end A rbeitsstation) which enables automatically to individual workstations according to a fault or an unwanted change back to the original previous state by a disk image reflect from the school server.

The sample solution includes a number of important network functions that are tailored to the educational, organizational and technical requirements of a school:

  • Lesson design
    • Support for multimedia presentation techniques
    • Internet access and personal email address for all teachers and students
    • Personal registration in the network: The familiar working environment is available on every computer
    • Temporary internet and e-mail blocking by teacher PCs
    • Targeted control of print jobs via web interface
  • safety
    • Parental controls
    • Backup and restore of computer configurations at the push of a button (SheilA)
    • Control functions on the server in the form of protocols
    • Class work in a secure exam environment
  • maintenance
    • Server-based user administration, import functions for user data
    • Automatic software distribution after a one-time installation
    • Formation and coordination of project groups by granting group-specific rights

development

The idea of ​​a standardized model solution arose in the late 1990s at the State Academy for Teacher Training (now: State Academy for Further Education and Personnel Development in Schools ) in cooperation with the State Institute for Education and Teaching (LEU) (now: State Institute for School Development (LS)) . While advanced training courses tailored to the model solution took place at the state academy, teachers at the state institute for education and teaching (LEU) developed a technical solution for using their experience as network consultants, which officially introduced the state's multimedia recommendation in 2002 the operation of an educational school network . One element of this concept is the Sheila ( S ven healing end A rbeitsstation), the first implementation in the first preview version of such a model solution was included. It was released in 1999 based on Novell's NetWare 5 . In June 2001, the model solution was published for the first time in its current form (as a data carrier). Many schools are using this solution satisfactorily. Thereupon the interest on the part of politics and the Ministry of Education increased.

A media advisory council convened by the Ministry of Culture with representatives from industry, publishing houses, universities and the municipal state associations ( County Council , City Council and Municipal Council ) made the decision in May 2000 to develop model solutions. As a result, the teacher training department (department 23) at the Baden-Württemberg Ministry of Culture took on the further development of the existing model solution in 2001 in the so-called media offensive I (MOI) by the central planning group for networks (ZPN) and also expanded the concept to include the Windows and Linux operating systems. The first versions of the Windows and Linux sample solution appeared in May 2002.

In September 2003 they moved to the Baden-Württemberg State Media Center, which was founded in October 2001 , where the Support Network project took over software development, school network consulting and technical support as part of the Media Offensive II (MO II). The project was originally planned until the end of 2006, but was extended by one year to December 31, 2007 and then made sustainable. In July 2012, however, the state media center announced that it wanted to outsource the previous development of paedML Linux to a company, since the rapid technological development made it more and more difficult to meet the high demands. The order for the development should go to the Bremen-based Univention GmbH, which in future will create a paedML Linux based on the Univention Corporate Server @ School , which is adapted to the needs of the state media center. In February 2013 this new collaboration was officially announced. On July 8, 2014, the “new” paedML Linux 6.0, which has been based on UCS @ school since this version, was presented to the public.

financing

The project's income is generated in addition to the sale of support contracts (per installation and year for schools in Baden-Württemberg between 275 euros (paedML Standard) and 325 euros (paedML Plus) or 650 euros (paedML Standard) and 800 euros (paedML Plus) for schools outside Baden-Württemberg) also from a grant of 1.6 million euros (including a portion for SESAM ) as part of the municipal financial equalization scheme .

With this business model, the Linux sample solution can be referred to as open core software . In the migration guide of the Federal Government Commissioner for Information Technology , open core software is defined as follows:

"

  • The core of the software is under a copyleft license (see section 3.4) such as the GNU General Public License (GPL).
  • A commercial license is required to use the core components in a proprietary product.
  • Additional functions and / or additional platforms for the core product are offered against payment. "

distribution

The model solution is used in all types of schools in Baden-Württemberg. These include 740 primary schools, 1400 general education schools and 280 vocational schools. 58 percent use paedML Windows, 25 percent use the Linux sample solution and 17 percent use the Novell variant.

For a certain period of time there was no offer for schools outside the state of Baden-Württemberg to use paedML with the support of the Baden-Württemberg State Media Center. However, following a resolution in November 2009, this option was re-created. This can also be seen in a communication on customer development published in February 2015.

The sample solution on different operating systems

The sample solution exists in three different versions, each based on different network operating systems:

The Windows sample solution

The Windows sample solution (paedML-Windows-Version 3) is operated on the server side with Windows 2012 Server (Version 1.5 to 2.8 Windows 2003 Server , Version 1.1 Windows 2000 Server ), the workstations run with Windows 2000 or Windows XP. User administration works with the help of an Active Directory structure; the software distribution runs via Windows Installer . The workstations can be restored using the RIS (Remote Installation Service) (SheilA principle), whereby the operating system and the associated components are reinstalled from the server. Network operation is possible with up to three servers (one to three server solution).

PaedML Windows 3.0 will be released for the 2014/2015 school year (summer 2014). It has been available since August 1, 2014. These are based on a Windows Server 2012 and SharePoint Foundation Server 2013 (including a. Microsoft SQL Server 2012); In addition, the firewall (OctoGate) and the software distribution ( OPSI ) each require their own server. All four servers are virtualized using VMware vSphere Hypervisor (ESXi).

The Linux sample solution

The Linux sample solution (paedML Linux version 6) works with the server operating system Univention Corporate Server @ school (version 3 to 5.1 Debian 4 and 5, version ML2 Suse Linux 7.0). The operating systems Windows XP Prof. , Windows 7 or Linux (with limited use of the educational functions - change to Debian 7 planned earlier Ubuntu 10.04) are available for the workstations . The user administration (up to version 5.1) is handled by Sophomorix . The software distribution is done by creating an image of a sample workstation, which is then distributed to all workstations. The hard disk recovery (SheilA) runs via OPSI (formerly LINBO up to version 5.1 or Rembo / mySHN up to version 5.0). All three servers (Univention Corporate Server @ school, pfSense , OPSI ) are virtualized by the VMware vSphere Hypervisor (ESXi). Multi-server operation is possible. In July 2012, the state media center announced that it would outsource the previous development of paedML Linux to a company. A little more than six months later, in February 2013, Univention GmbH announced the partnership with the state media center. The state media center of Baden-Württemberg and Univention presented paedML Linux 6.0 to IT school service providers and the public in July 2014, around two years after the announcement that they would commission a company with the development.

In addition to the Linux sample solution, there is a fork of the free school server solution linuxmuster.net (see Linux sample solution ), which is now based on Ubuntu and is developed and maintained as an open source solution by a free community.

The Novell sample solution

Structure of the Novell sample solution (status: 2006)

The Novell sample solution (paedML Novell Version 4) is based on SUSE Linux Enterprise Server (SLES) 11SP3 including the Open Enterprise Server 11 SP2 and GroupWise 2014 SP1 (Version 3 Open Enterprise Server, Version 2 Novell NetWare 6 , Version 1.1 Novell NetWare 5 ) on the server side ), the workstations can be operated with Windows XP Prof. , Windows 7 Prof. , Windows 8 or Windows 8.1 . The user administration uses an eDirectory structure adapted to the specific school . The software distribution and client administration work with ZENworks . The workstations can be restored using rule-based, central image management. GroupWise is used for e-mail and calendar management. In addition to the main server, the paedML Novell uses a server for ZenWorks-11, based on SLES11 SP3, if Windows 7 or 8 clients are to be managed. Expansion options offer a collaboration server with Novell Vibe, based on SLES11 SP3 with Novell FILR also one running on SLES11 SP3 server for cloud-based file management.
