Details: *This is a 4 day course

Description

Learn the skills to configure the common network services and security administration using Red Hat Enterprise Linux.

Red Hat training and certification for Red Hat Enterprise Linux 5 is not just valuable for those professionals who will be working with it immediately. It is also valuable to professionals working on earlier releases of Red Hat Enterprise Linux. While Red Hat Enterprise Linux 5 does introduce new capabilities and technologies, the core system administration tasks one must learn and master as system administrator are far more similar to previous releases than different. Consequently, those who train on Red Hat Enterprise Linux 5 should adjust easily to earlier releases, while also having an understanding of the potential and opportunity that Red Hat Enterprise Linux 5 presents.
