Users are imported via csv files in a web based UI (WebUI). In the background, the sophomorix tool creates, moves and deletes users.

Users remain in the system throughout their school careers with their registration data and documents. Every school year they are simply "transferred" by re-reading the current data from the school administration.

All user data is stored in an AD (samba4 - LDAP compatible database), which can be used by external sites (room booking, WebUNTIS, moodle, ...)


No - in practice, it quickly becomes apparent that it happens again and again that pupils have forgotten their passwords. Teachers can assign a new password to each student account.

Teacher passwords can only be reassigned by the administrator.

Every user of the system can change his own password in WebUI at any time.

Of course, because a pupil does not have the same rights and tasks in the system as a teacher or network administrator. For this reason, the WebUI also adapts to the role of the registered user.

In principle, it is possible to operate virtualized with any virtualization solution (VMware, Proxmox, KVM or similar).

The decision to virtualize by default with Proxmox was made because Proxmox is open source with all its features and is still an "Enterprise Grade" virtualization solution for which support is available from qualified service providers. It is easy for use in a single-server school solution as administrative tasks can also be undertaken via web access.

Yes, from the WebUI, users of the system can access all the functions that correspond to the permissions of your role.

The WebUI is the system's control center. For example, a teacher can start teaching in a room and control access to the Internet.

You can create project groups to treat upper-level courses, subclasses or workshops like a class.

Officially supports Windows 10 and 11 - and of course Linux, which only a few school server solutions can do.

Linux runs with a single hard disk image on almost any hardware.

Because of Linux' open source licenses the first installation of a complete school (server and clients) can be completed in just a few hours.

No, the community has been active all over Germany for many years.

Of course, the number of schools with is highest in the home country of the system, but there are also installations of outside Germany - for example at German schools abroad.

We are currently developing in the direction of bilingualism, so that both the system and the documentation will be available in German and English.

No matter where you are, the community will support you.

The purchase and use of linuxmuster. net is free of charge, as it is a concern of the association around to support the FOSS idea (free and open source software).

In conjunction with the Ubuntu client operating system provided by us, a school network can be operated without license fees with free software.

A school can, if you wish, join as a sponsoring member and in this way, with a self-determined annual fee (min. 36 EUR). This is also secures the further development of The money will be fully used for further software development and for the provision of the necessary infrastructure.

But depending on which operating system and software you want to work with, as with any other IT system, you may incur costs from another side:
If you are using Windows, you must have a sufficient number of valid licenses for this purpose, as well as for commercial office packages or other non-free software that is subject to a fee. The setup and maintenance of the system is usually costly for a service provider to perform these tasks for you.

Support for rests on several pillars:

  • In the Supportforum you will find numerous experienced users and service providers at your disposal. Usually, everyday problems are solved there within very short response times.
  • Tuesdays between 14 and 18 o' clock (CET) our telephone hotline is available to you under the number +49 721-17028011.
  • Numerous IT service providers offer case-by-case support and support contracts for The service provider does not necessarily have to be "on site", as can be easily maintained remotely via secure channels.
