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

• Red Hat System Administration I and II or RHCSA Rapid Track Course
• RHCSA certification holder or equivalent experience
• Have 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 file system)
  • File system management (using fdisk and mkfs)
  • Basic troubleshooting (including managing log files and perhaps the use of hardware probing tools, such as ethtool and lspci)

Troubleshooting is both an art and a science. An instinct and a technique. In Red Hat Linux Troubleshooting (RH242), system administrators will learn techniques for troubleshooting a Linux system and how to use the troubleshooting tools available on Red Hat Enterprise Linux. This course is a four-day, heavily lab-oriented class designed to help the student learn or improve troubleshooting skills. Students will gain troubleshooting experience by debugging live, virtualized systems.

• Introduction to troubleshooting techniques, including being prepared
• Troubleshooting hardware, including listing, testing, and analyzing devices
• Troubleshooting applications, including diagnosing performance problems and investigating application and OS interactions
• Troubleshooting disks and file systems, including LVM, LUKS, ext3/4, and unauthorized changes
• Troubleshooting the network, including configuring, testing, and diagnosing problems with basic and advanced configurations
• Security, including working effectively with (and not against) security tools like SELinux, authentication, and firewall
• Making the most of Red Hat support resources
