Troubleshooting Linux

This presentation will cover basic troubleshooting strategies and tools available for most Linux distributions. We start by by covering how to be prepared for troubleshooting – documentation, backups and spares. Then we'll look at logs and using debug options and command history to assess the scope of the problem. Troubleshooting the X11 subsystem and the GNOME Desktop Environment is explained. We'll review how to monitor and manage general processes. We'll discuss how to check important settings and preferences. Networking, both wired and wireless, is another key area that is covered. Key command line and graphical tools for diagnostics and configuration are explained along with the important configuration files and how to verify them.
