PrefaceThis book is supposed to help Network Administrators to understand how FreeBSDcan help them simplify the task of network administration and troubleshooting aswell as running various services on top of FreeBSD 7 Operation System. FreeBSDis a proven Operating System for networked environments and FreeBSD 7 offerssuperior performance to run network services, as well as great flexibility to integrateinto any network running IPv4, IPv6 or any other popular network protocol.This book is divided into three segments—system configuration, networkconfiguration, and network services.The first segment of the book covers system configuration topics and talks aboutdifferent aspects of system configuration and management, including disksmanagement, patching and keeping the system up to date, managing softwarepackages, system management and monitoring, jails and virtualization, and generalimprovements to system performance.Second segment of the book actually enters the networking world by introducingbasic network configuration in FreeBSD, network interface configuration for differentlayer 3 protocols, Tunnelling protocols, PPP over serial and Ethernet and IPv6.This segment also looks into bridging and routing in FreeBSD using various thirdparty softwares. At the end, there is an introduction to various firewall packages inFreeBSD and details on how to configure them.Third segment of the book deals with different daemons and network services thatcan be run on top of FreeBSD, including Local network services such as DHCP,TFTP, NFS, SMB as well as Internet services such as DNS, Web, Mail, FTP and NTP.
PrefaceWhat This Book CoversChapter 1 looks into FreeBSD file system and disk I/O from a performance pointof view. Several methods to optimize the I/O performance on a FreeBSD host arediscussed in this chapter.Chapter 2 discusses several methods and tools to keep a FreeBSD system up-todate,including CVSUP to update source and ports tree and also customizing andupdating system kernel and rebuilding the whole system from source.Chapter 3 introduces FreeBSD ports collection, packages, and different methods toinstall, remove, or upgrade software packages on FreeBSD.Chapter 4 covers basic information about daemons, processes, and how to managethem. You will also get familiar with various system tools to monitor and controlprocess behavior and manage system resources efficiently.Chapter 5 discusses virtualization in FreeBSD and introduces Jails from ground up.This chapter covers creating and maintaining Jails and scenarios in which you canbenefit from these built-in virtualization facilities in FreeBSD.Chapter 6 discusses performance tuning from different perspectives, including DiskI/O and Network, and how to get the most out of the modern hardware andmulti-processor systems. It discusses various tweaks that can make your FreeBSDsystem perform much faster and more smoothly.Chapter 7 deals with network configuration in FreeBSD in general, focusing mostlyon network interface configuration for different network protocols such as IPv4,IPv6, IPX and AppleTalk. It also deals with basic network configuration andrelated configuration files and finally introduces some network management andtesting tools.Chapter 8 discusses tunneling in general and introduces various tunneling protocols,and mostly concentrates on GRE and IPSec tunneling.Chapter 9 covers PPP configuration in FreeBSD including PPP over Ethernet protocolas both client and server.Chapter 10 has a closer look at routing and bridging in FreeBSD using built-inbridging features and also different routing protocols including OSPF and BGP usingthird-party software.Chapter 11 concentrates on IPv6 implementation in FreeBSD and gives more detailon interface configuration, routing IPv6 using RIP6, Multicast routing, andTunneling protocols.[ ]
