Red Hat Linux Troubleshooting Techniques and Tools [RH142]

Troubleshooting is both an art and a science, an instinct (typically informed by experience) and a technique. In RH142 Linux Troubleshooting Techniques and Tools, participants will learn techniques for troubleshooting a Linux system and will learn to use a variety of troubleshooting tools available on Red Hat Enterprise Linux.

RH142 Linux Troubleshooting Techniques and Tools is a 4 day heavily lab-oriented class designed to help participants learn (or improve) their troubleshooting skills using tools available in Red Hat Enterprise Linux. Labs will offer a range of problems from RHCT level and up to allow participants to extend their knowledge and techniques.

Participants will have the opportunity to debug live systems, exercising their new troubleshooting skills on a working system so that they can start to (or continue to) develop troubleshooting experience.
