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.

I think most people would agree that the 'r' commands should be avoided whenever possible, any reason you cant use ssh with key based authentication ?
Hi, actually i have some existing scripts which are using rsh for remote login, but we stopped using those scripts for a while, and now i am again trying to reuse those scripts for my task, i am just trying to avoid the rework here by using the same scripts, there is not strong reason for not using ssh , would it be possible to login wihtout password using ssh, if possible then how could i do that , it would be good if you mention the steps here.
To ssh to another host without being prompted for a password, you need to distribute your ssh public key to the destination host. The utilites I mentioned will do this for you, it can also be done manually.
Once this process is complete you will be able to run a script on the remote host as you require without being prompted for a password
