Babak Farrokhi says, this book is a guide to FreeBSD for network administrators; therefore it does not cover basic installation and configuration of FreeBSD, but is about using FreeBSD to build, secure, and maintain networks.
After introducing the basic tools for monitoring the performance and security of the system the book moves on to cover using jails—FreeBSD virtual environments—to virtually run multiple instances of FreeBSD on the same hardware. Then it shows how to overcome the different bottlenecks that you may meet depending on the services you are running by tweaking different parameters to maintain a high performance from your FreeBSD server.
