TCP/IP and UNIX, both born in the research community, have experienced phenomenal growth and commercial success over the past decade. TCP/IP is the network protocol family of choice on the Internet, the largest and fastest growing data communications network in the world today. UNIX systems, with their mature support of TCP/IP, are a central and growing part of many organizations' networking strategy. Through a careful blend of network theory and practice, these two network authorities provide readers with the knowledge to understand what TCP/IP is, how it works, and how to use it to build practical and working network systems that are both extensible and maintainable. Practical Internetworking with TCP/IP and UNIX, the third in the UNIX and Open Systems Series published by Addison-Wesley, describes in detail how to set up and manage a TCP/IP network using the tools available within the UNIX operating system. Systems designers, network administrators, and system programmers will find the TCP/IP knowledge they need in this concise volume.
