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.

Thank u for reply.
The terminal doesn't complete "ifcfg-eth0", it completes until
It doesn't have the option of "ifcfg-eth0", therefore i cannot reach the file in order to configure IP parameters.
Ok, now I understand what you mean.
So what ifcfg-files do you have? ("ls /etc/sysconfig/network-scripts/ifcfg-*") You see, "eth0" is just a name and could be anything - although eth0 is probably the most common.
If there is no ifcfg-file at all there is some other problem, we'll look into it then. You could start with checking the file "/etc/udev/rules.d/70-persistent-net.rules"
Is this a vmware guest?

You are not very clear, I'm not sure what you're actually doing.
What do you mean with "write the path "/etc/sysconfig/network-scripts/ifcfg-eth0"?
Please post output of:
ls -l /etc/sysconfig/network-scripts/
results of cat /etc/udev/rules.d/70-persistent-net.rules
This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
According to your udev output you have 2 nic's, eth0 and eth1. It could also be that you replaced a nic, in some occasions "eth0" is not replaced but a new nic "eth1" is created.
One important thing is whether this is a vmware guest or not, that question is still unanswered? If it is, we might need to look at vmware's config for the guest.
You could try to copy ifcfg-eth0 to ifcfg-eth1, see if you can bring up eth1 then.
And again, what exactly do you mean by "write the path "/etc/sysconfig/network-scripts/ifcfg-eth0""?
The file exists and is writable by root. What exactly did you do?
Ah I see! You don't execute that file, it's read by system.
What you do to bring up the interface is command (as root or using sudo) "ifup eth0".
Maybe it's already in state up (can be even without ip) then you bring it down first "ifdown eth0".
In the file /etc/sysconfig/network-scripts/ifcfg-eth0, you can delete the line "UUID=..". Also HWADDR is not necessarily needed, you already have set DEVICE=eth0. No problem keeping it though.
If eth0 doesn't work as it should, try copying ifcfg-eth0 to ifcfg-eth1, change DEVICE=eth1 and HWADDR=00:0C:29:4B:FF:33
Then try "ifup eth1"
In network-scripts directory was additional file named etho-lo, but I didn't find file of eth1, moreover the network-scripts directory doesn't permit to add/delete files.
Parameters of ifcfg-lo file:
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
