Linux administration involves a fair amount of interaction with system hardware and the kernel, as well application of a large number tools and applications. This course provides a hands-on approach to acquiring the key system administration and management skills.

As we traverse the administrative, networking and troubleshooting topics, we incorporate good practice, performance and security elements, all aiming to achieve a high level of proficiency in working with at the command line.

With its distinctive design approach, this course is also suitable as a Unix to Linux conversion for existing Unix administrators. It is a fast-paced skills-building event, full of practical exercises and troubleshooting.

The course platform will be one of the Red Hat derivatives, such as CentOS or ScientificLinux. However, the discussions and material address every major Linux strand, and wherever specific tool, technique or method is relevant, SUSE, Debian and Ubuntu specifics are covered. For example, we discuss the unique approach adopted by various systems in the areas such as system start-up and software management.

Target Audience:

All existing administrators, developers, analysts, indeed, all users who find themselves looking after a Linux box. Also, experienced Unix Administrators who need to port their skills to Linux.

  • Delegates should have previously attended the 'QALXESS-2, Linux System Fundamentals' course, followed by several months of practical experience of working with Linux (or have equivalent skills)
  • Alternatively, they should have solid experience of administration of any Unix version

At the end of this course you will be able to:

  • Compare various Linux distributions
  • Understand Linux versus UNIX administration
  • Understand the methods and ways of installing a Linux system
  • Use the modular kernel architecture and re-configure it to suit a specific need
  • Interrogate, manage and configure hardware
  • Install additional software: pre-packaged and from source code
  • Perform automated software updates
  • Configure and troubleshoot boot and operating system start-up process
  • Implement and manage partitions and filesystems, including LVM
  • Maintain file system security, including using chattr and ACL
  • Understand Mandatory Access Control with Selinux and Apparmour
  • Enhance user and session security with PAM
  • Connect with SAMBA and CIFS
  • Use SSH for secure connectivity
  • Perform basic network configuration, security and troubleshooting
  • Handle packet filtering with iptables and firewalld
