5 Great Open Source Apps We Use In Our School
Last Updated on
Since 1.5 years our school uses almost exclusively Open Source software. This step has already saved us more than 5000€ in license costs in this short time. But that’s not our main reason for using open source software. The reasons are as follows:
- Freedom and independence from a vendor
- the low administration effort (Ubuntu client vs. Windows 10 client)
- Flexibility and integration capability of open source programs to adapt them to our existing structures
- and some more (hardware can be used longer, etc.)
Today I would like to introduce 5 open source programs, which we use and that make life easier for us in the IT everyday life of the school.
Linuxmuster.net is in my opinion the best free sample solution currently available for schools. It forms the heart of our infrastructure (DNS, DHCP for the LAN, LDAP, Samba, RADIUS). It’s not only the software that’s great, but also the community around this project. I have seldom experienced such a friendly and helpful community that you can really ask about everything to do with school and IT.
A part of Linuxmuster.net is LINBO, a mini OS that allows you to manage all computers in your network. With the help of images you can restore all computers to a defined state at any time (also offline). LINBO does not only support Linux, but also Windows. With the help of postsync-scripts, you can customize the computers individually or room by room without having to maintain 5 different images. For example, we provide teachers’ computers or students’ computers in the classrooms with a different configuration than the computers in the computer lab.
- Captive portal with RADIUS authentication and vouchers
- SNMP / check_mk integration for our monitoring
- High availability and hardware redundancy
- HAProxy (Reverse Proxy) to distribute our subdomains to the right servers
- Squid (web filter, proxy)
We have been using the Open Monitor Distribution and Check_mk for one year now. It takes a little time to find your way around the interface, but Check_mk is very powerful and you can use it to monitor pretty much anything. We use it to monitor our entire network infrastructure (switches, firewall, UPS, access points, wireless controllers, printer ink levels) as well as our servers and some clients (digital signage). Furthermore, we also use a plugin that sends a notification to our monitoring channel in case of a problem (currently we still use Slack, but are want to upgrade to Rocket.chator Mattermost).
We only recently discovered Zammad. It’s the support platform we’ve been dreaming of for a long time. At the beginning we used OSTicket, which also works well but does not have a modern and responsive user interface. Zammad offers us everything we want:
- LDAP support
- modern surface
- many integrations / channels (email, telegram, web,…)
Currently, we use Zammad only for IT inquiries from employees or teachers. In our school we have other forms for repair requests, class trips etc. In the future we want to migrate them to Zammad.
Documentation: Admin-Documentation and User-Documentation
Since this school year we have been managing our school and teaching materials library with Koha. I had reported on the migration in the last few months. Koha is a very powerful tool for managing libraries and it’s not that easy to get started, because you have to deal with topics like Marc21 and many other bibliographic things to configure Koha correctly. However, you can easily simplify the whole thing without any problems, so that you only use some of the features.
There are a lot of great open source projects and I could mention some more. A school, which runs with almost 100% open source software, is no longer a problem these days. There are many examples of this worldwide. I personally see the biggest obstacles in convincing employees and decision-makers, as well as capable IT employees.
