Course Description

RH290 Red Hat Enterprise Linux for Solaris Administrators quickly and efficiently covers many of the hands-on, practical skills needed when migrating from Solaris to Red Hat Enterprise Linux. Focusing on the differences between the two operating systems, the course covers Red Hat Enterprise Linux equivalents to Solaris-specific technologies, such as applying software patches, automated deployment with Jumpstart, and advanced filesystem features. In addition, the course demonstrates how to use RPM, yum, the Red Hat Network (RHN), and Kickstart to manage your environment. You will acquire and set Linux kernel tunables, explore and configure the many supported hardware devices available from multiple vendors, and secure your users and services.

Upon completion of this course, you will have the knowledge and skillset to take RH253, Red Hat Linux Networking and Security Administration, or the RH300 Rapid Track Course.

This class leverages existing UNIX-based skills to build RHEL expertise.
