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.

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.

The first machine out of the lot was installed(OS) the traditional CDROM installation. The rest of the machines we used a combination of dump and cp commands(Change hostname and IP address later) to install the operating system
Now these machines which were dump/copied are having a strange network problem, when I reboot these machines the network does not work. If I reboot the same machine once more it starts working.
Furthermore , if the network doesn't work I pull the network cable and plug it back the network wakes up.
What might be the problem?
I have changed the hostname(/etc/sysconfig/network) and the network card parameters (/etc/sysconfig/network-scripts/ifcfg-eth0), /etc/resolv.conf and /etc/routes after the cp and dump.
Do I need to change anything else?
Where does the machine get the proper MAC address for the NIC card ?(/etc/sysconfig/network-scripts/ifcfg-eth0 or from the NIC itself)
