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.

I need help to copy files from one CentOS system to another one.
The files are generated automatically at one server, and i want to copy them immediately to an other server.
Please can anybody help me?
Do actually mean immediately? As in as soon as they are created on one server they must be visible on the other server with no delay? If so then assuming the machines on the same LAN put the files that are being created in their own location and then export that location with NFS (limit the export to the IP address of the other server). Then mount the exported filesystem on the other server (probably mount it read-only unless you really need the other sever to alter the files). You could go a step further and use something like ionotify on the other server to detect the creation of files and trigger a script to do something with them.
If you don't really mean immediately then just periodically copy the files using rsync with ssh keys called from a cronjob as others have suggested.
