Linux - Crash course for Administrators

Five day basic course for Linux system-administration, including network topics

One week all-inclusive - that is the vision for this inovatively-structured Linux seminar for would-be administrators. The seminar is self-contained and complete, and covers all themes relevant to server administration. In contrast to typical courses, it does not represent a small element in a long sequence leading to a certification, rather it enables a very pragmatic and rapid introduction to Linux. When course topics were selected, typical desktop themes such as the graphic interface, KDE and GNOME were consciously-excluded, the course concentrating instead on network themes including the configuration of NFS, SAMBA and Apache, and administration with SSH. Course participants will not simply come away with a basic knowledge, but rather with practical knowledge for deploying Linux for the most important applications. All topics covered in the course are basically independent of a specific Linux distribution, and are equally applicable to SuSE, Red Hat, Debian, Ubuntu and other distributions - even if the instructor occasionally touches on special characteristics of one or another distribution.

  • €2.796,50 (inkl. Mwst.)
  • für Future Linux-Administrators Software developers all those who at least occasionally want to, or must work with Linux

Upon course completion one will be capable of administering a Linux system using the command line, regardless of the distribution in use. You will know all important and standard commands and configuration files. You will understand the boot process, and know how to deal with the system when it doesn't start correctly. You will be able to integrate a Linux system into a network, and be able to precisely identify and correct errors. Furthermore, you will be able to configure and productively operate the NFS, Samba and Apache data services, and likewise be able to administer Linux systems remotely via SSH - including from Windows.
