The book by Michael Lucas, one of the active participants in the FreeBSD project, is a detailed guide to the powerful and free free FreeBSD operating system that many enterprises use as their main server platform. The book discusses in detail the installation of the FreeBSD operating system, networking, security, system performance, fine-tuning the kernel, file systems, updates, troubleshooting possible system problems and failures, and software management. After reading this book, you can use FreeBSD to provide network services, learn how to manage, maintain, and patch FreeBSD systems. The book will be useful for system administrators who support FreeBSD in organizations and are of interest to users planning to use FreeBSD on their work computer or combine desktop server systems.
