Linux Containers and Virtualization
Get a novel perspective on Linux containers and understand the world of virtualization. This book takes you down the rabbit hole to discover what lies below the API. You'll go on a journey of virtualization and see how containers are realized in the Linux world. Linux Containers and Virtualization details the data structures within the Linux kernel which make up Linux containers. You will start with the fundamentals of virtualization including how different resources such as memory, CPU, network, and storage are virtualized. Then you will move on to hypervisors and virtualization using the Kernel virtual Machine (KVM) and Quick Emulator (QEMU). Next, you will learn about Linux namespace, cgroups, and layered file systems, which are the essential building blocks of Linux containers. The explanation traverses the Linux kernel codebase to show how these are realized in the Linux kernel.

Professional Linux Programming
As Linux continues to grow in popularity, there has never been more of a need to understand how to develop for this platform. Rather than focusing on a particular language or development technique, Professional Linux Programming looks at the different development environments within Linux - the kernel, the desktop, and the web - and then demonstrates best practices, tools, and techniques for integrating applications with the OS as a whole. This book is essential for understanding the nuances that differentiate programming for Linux from programming for any other platform. After beginning with simple shell scripts, the reader quickly moves on to the more advanced topics like software drivers and the graphical interface. The wide variety of tools that you can use to build application software, utilities, and even the Linux kernel itself are covered. You'll also explore the unique components of a Linux system and delve into the inner workings of the system. And you'll find out how to u ...

Linux Firewalls
System administrators need to stay ahead of new security vulnerabilities that leave their networks exposed every day. A firewall and an intrusion detection systems (IDS) are two important weapons in that fight, enabling you to proactively deny access and monitor network traffic for signs of an attack. Linux Firewalls discusses the technical details of the iptables firewall and the Netfilter framework that are built into the Linux kernel, and it explains how they provide strong filtering, Network Address Translation (NAT), state tracking, and application layer inspection capabilities that rival many commercial tools. You'll learn how to deploy iptables as an IDS with psad and fwsnort and how to build a strong, passive authentication layer around iptables with fwknop. ...
