Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

DHCP server is the one which assigns IP address, gateway, netmask , DNS entries etc to your machine.
Please check weather DHCP Server is configured properly. Because you are getting No DHCPOFFERS received. as error. You have told that you have changed the LAN card. So MAC address might have got changed.
Change your old MAC address entry in DHCP server to new one.
Paste your /etc/dhcp.conf configuration file contents here.
What are you trying to do?
You need ip to your system or want to configure dhcp server?
From dhcp server you will get ip?
You dont need to configure your system as dhcp server to get ip on your own system.
From some one get the details of how you get ip's to other system on network ...is it manually set or you get it through dhcp?
