Linux Troubleshooting


This training designed to give Linux administrators experience with both common and uncommon system problems.

Class starts with a discussion of effective troubleshooting technique. Tools and topics are gradually introduced over the course of the week. Students practice applying these tools and techniques in self-paced labs. Students can choose from over 120 scenarios organized by topic and difficulty. Because each scenarios is independent of the others, students can choose scenarios according to their interests and experience. Each scenario is designed to help students develop deeper understanding while exploring the problem.

Students find the flexibility and challenge of this course very rewarding.
