Inhalt: What lies at the heart of the Linux operating system? The Linux kernel. Every Linux professional-including those in system administration, operations, and software development-needs to be familiar with the functionality of the Linux kernel as well as the mechanics of configuring and troubleshooting it. Master the fundamentals in this course with Kevin Dankwardt. Kevin surveys the Linux kernel specification, boot process, and loadable kernel modules. He provides opportunities for you to practice techniques such as searching Linux kernel source code and configuring a Linux kernel from scratch. Challenge and solution videos at the end of almost every chapter allow you to test your new Linux skills along the way. Umfang: 04:05:21.00

Inhalt: One of the most important functions of any operating system is managing various types of hardware connected to the system, from simpler items like serial ports and keyboards to more complex hardware like USB cameras, hard drives, and networked devices. By understanding how Linux device drivers function, you can derive useful insights into the behavior of the Linux kernel and how users and developers can-and cannot-interact with devices. In this course, Kevin Dankwardt explains how loadable kernel modules work, then details three different types of Linux device drivers-character device drivers, block drivers, and network drivers-and the aspects and uses of each. Kevin covers the basics of each type of driver, and then guides you through writing, debugging, tracing, and adding functionality to the different device drivers. Umfang: 02:49:16
Inhalt: DevOps pros, system admins, and software developers all benefit from knowing how to determine bottlenecks, find resource usage information, and improve the performance of Linux systems. Linux performance tuning makes sure you're getting the most from your machines. This training course demonstrates a variety of tools and techniques to help you diagnose and repair problems related to resource usage and allocation. Learn how to identify bottlenecks in memory, CPU, and disk, by using tools such as perf, sar, top, htop, atop, Performance Co-Pilot, and many more. Explore the proc filesystem, and concepts such as swapping, paging, and page faults. Instructor Kevin Dankwardt also discusses Linux process scheduling, and relates topics to objectives covered by the Red Hat Certificate of Expertise in Performance Tuning exam (EX442).

Inhalt: Bash scripting can help you automate routine tasks and save valuable time, whether you're a Linux user, sys admin, or software developer. Kevin Dankwardt has written thousands of bash scripts, short and long. Here he teaches you how to read and write scripts, and provides a series of scripting challenges to help you test your new skills. Learn about the bash environment, local variables, functions, loops, case statements, string operations, and coprocesses. Plus, learn how to use the text processing utilities sed and AWK to read and edit data in text files. The topics covered in this course are vital for Linux administration, and required for many Linux certifications. Umfang: 02:46:22.00
Inhalt: Managing storage in Linux involves both conceptual understanding of volumes and partitions, RAID, and Linux file systems, as well as hands-on knowledge of how to accomplish important tasks involving storage. This course shows how to deal with these topics and many different storage scenarios, including clustering, high availability, and security. Kevin Dankwardt shows how to create, mount/unmount, and format file systems including ext4, XFS, and Btrfs; use the Logical Volume Manager (LVM); enforce security with SELinux and access control lists; swap space; back up and recover Linux storage; and work with networked files systems-distributed, clustered, and FUSE based-like SSHFS. These are essential skills for any Linux admin, especially those who desire Linux Foundation Certified System Administrator (LFCS) certification. Umfang: 03:30:03.00
