Introduction:
 
Troubleshooting is both an art and a science-an instinct (typically informed by experience) and a technique. In this course, you will learn techniques for troubleshooting a Linux system, and you will learn to use a variety of troubleshooting tools available on Red Hat Enterprise Linux (RHEL).

This lab-oriented class is designed to help you learn (or improve) your troubleshooting skills using tools available in RHEL. Labs offer a range of problems from RHCT-level and up to allow you to extend your knowledge and techniques. You will have the opportunity to debug live systems, exercising your new troubleshooting skills on a working system so you can begin or continue to develop troubleshooting expertise.
 
Audience:
 
Linux system administrators who understand how to install and configure a Red Hat Enterprise Linux system and who wish to deepen their understanding of troubleshooting on Linux; Current RHCTs, RHCT candidates, or UNIX System Administrators who have equivalent experience
 
Prerequisites:
 
RHCT certification, successful completion of RH131 or RH133, or equivalent system administration knowledge under Red Hat Enterprise Linux, including installation, service management (using service and chkconfig, for example), basic system monitoring (using ps and top, and perhaps meminfo and the /proc filesystem), filesystem management (using fdisk and mkfs), and basic troubleshooting (including managing log files and perhaps the use of hardware probing tools such as ethtool and lspci)
 
Customize it:
 
This 4-day LINUX course will be customized to your needs and specifications. Eno.com will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of Linux training. They will typically have a broad and general course, one size fits all, already developed and just put your organization?s ame on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren't too sure of what that was. We fit the class to your needs. We never fit you into our standard, one size fits all, class.
