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.

Thanks for suggestion ,but To avoid network traffic on one interface i have use 2 interface from last 2 years there is no issue from my above logs i.e someone advertises our address on eth1! it means that someone use this same ip on some where
as i have more than one application in my server and if all user accessing same application at same time then the application is slow for this i use 2 interface , the error log as posted above is due to this like error "someone advertises our address on eth0"
