Overview

In “Linux Networking” we combine fundamentals and practice: you get to know ip, ss and network configuration, Bonding, bridges, VLANs and Routing and policy routing, apply what you learn in exercises and receive templates and checklists for your own use.

Linux and Unix form the backbone of servers, cloud platforms, databases and network services. Anyone running these systems needs confident command-line skills, a clear understanding of file systems, services and networking, and the ability to narrow down problems quickly. Our Linux Networking courses are aimed at beginners, administrators and operations teams who want to consolidate or deliberately extend their knowledge. We work exclusively on real systems in a provided lab environment: you type, fail, analyze and solve. The course runs online or on site, lasts one day and is offered at a fixed price per participant.

The course is delivered live – either online in a virtual classroom or on-site in our training rooms in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run it exclusively for your team.

Frequently asked questions

Do I need prior knowledge for Linux Networking?

That depends on the level. Entry-level courses assume no Linux knowledge, while advanced Linux Networking courses expect solid command-line basics. If you are unsure, we are happy to recommend the right starting point in a short pre-call.

Do we work on our own systems or in a lab environment?

For Linux Networking we provide a lab environment with real Linux or Unix systems that you access via SSH. That lets you configure safely and provoke failures on purpose. You do not need your own systems, but you are welcome to bring your own questions.

How much does “Linux Networking” cost?

The course costs a flat €949 plus VAT per participant – whether online or on-site. This includes 6 hours of live training with a trainer, course materials, a lab environment and a certificate of attendance.

Can I suggest my own date?

Yes. For every location we suggest a date roughly four weeks ahead. In the request form you can always describe your preferred date or period in free text – we check availability and get back to you within one working day.

Is the course online or on-site?

Both are possible: live online in a virtual classroom or on-site in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run the course exclusively for your team.

Can the course be tailored to our team?

Yes. Tailor-made courses cost approx. €4,500 more, depending on the topic and by arrangement. We agree content, examples and exercises with you in advance.
