The IP stack of Linux is very flexible. If you are a network administrator, or if you would like to know more about how to use the Linux-specific features of the IP stack, how to diagnose ARP problems or how to understand routing under Linux, then this document may be for you.
This guide provides an overview of many of the tools available for IP network administration of the linux operating system, kernels in the 2.2 and 2.4 series. It covers Ethernet, ARP, IP routing, NAT, and other topics central to the management of IP networks.
The book is available in chunked HTML, single-page HTML, and PDF formats.
