Technical requirements
Before going any further, I think is important to acknowledge here that certain technical topics may be more challenging for beginners to comprehend than others. Since the goal here is to comprehend the inner workings of the Linux kernel and its major subsystems, it will be helpful to have a decent foundational understanding of operating system concepts in general and Linux in particular. Above all, it is important to approach these topics with patience, curiosity, and a willingness to learn.
The commands and examples presented in this chapter are distribution-agnostic and can be run on any Linux operating system, such as Debian, Ubuntu, Red Hat, and Fedora. There are a few references to the kernel source code. If you want to download the kernel source, you can download it from https://www.kernel.org. The operating system packages relevant to this chapter can be installed as follows:
- For Ubuntu/Debian:
sudo aptinstall stracesudo aptinstall bcc
- For Fedora/CentOS/Red Hat-based systems:
sudo yuminstall stracesudo yuminstall bcc-tools
