Linux Ethernet-Howto Linux Ethernet-Howto by Paul Gortmakerv2.66, 6 July 1998This is the Ethernet-Howto, which is a compilation of information about which ethernet devices can be used for Linux, and how to set them up. It hopefully answers all the frequently asked questions about using ethernet cards with Linux. Note that this Howto is focused on the hardware and low level driver aspect of the ethernet cards, and does not cover the software end of things like ifconfig and route. See the Network Howto for that stuff.1. Introduction1.1 New Versions of this Document1.2 Using the Ethernet-Howto1.3 HELP - It doesn't work!2.
