Description

The GNU/Linux system has established itself as a serious alternative in the business server segment. This training will allow you to master the behavior of your Linux servers while having real autonomy in diagnosing system malfunctions. You will also learn how to optimize your servers and have the right tools at all levels.

Who is this training for ?

For whom ?

Administrators, system engineers.
