Passionately democratic in its advocacy of networking for the masses, this is the first book on Linux networking written especially for the novice user. Because the free, open-source Linux operating system is winning so many converts today, the number of Linux-based networks will grow exponentially over the next few years. Taking up where Linux Clearly Explained left off, Linux Networking Clearly Explained walks the reader through the creation of a TCP/IP-based, Linux-driven local area network, beginning with a sandbox installation involving just two or three computers. Readers master the fundamentals of system and network administration-including handling user accounts and setting up security-in this less complex environment. The author then helps them along to the more sophisticated techniques associated with connecting this network to the Internet.

* Focuses on the 20% of Linux networking knowledge that satisfies 80% of network needs-including the needs of small businesses, workgroups within enterprises and high-tech homes.
* Teaches novices to implement DNS servers, network information services (NIS), network file systems (NFS), and all of the most important TCP/IP services, including email, Web and newsgroup access.
* Explains how to set up AppleTalk and Windows NT domain servers for networks that include MacIntosh or Windows systems.
* Comes with a CD containing the latest version of Red Hat Linux, as well as additional freeware/shareware Linux tools and network management applications.
