Start Lesson: Linux training: administer and secure a server

About this path · first level: 46 lessons, about 9 weeks

Welcome to your Linux training path. This page lists every lesson of the course available in English, grouped into progressive modules: fundamentals, system administration and RHCSA EX200 preparation. A lesson ticked in the French edition is ticked here too.

Yes, it is a long path. Nobody follows it in one go: it is split into levels. The first one, "Use a system", is 46 lessons of about 40 minutes: at one per working day, roughly 9 weeks, and it ends with its own result. Each module gives you a skill you can use the next day, and your progress waits for you in this browser and on the devices linked to your optional account.
