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.

in my new server , there is a directory , it is strange that when I use root user to create directory in it , the owner is nfsnobody , now I want to change the owner to edp user but it do not allow , the error is "operation no permitted" , can advise what is wrong ?
Do you mean "edp user" literally? I would imagine that the space would be an issue.
I assume that using "chown" to change the user on a file requires that the new username exists in /etc/passwd
No , I use the command
chown edp:user directory
but it is not work , I found the server is mounting to another server , but I can't find the mount by /etc/mtab /etc/fstab , df command , I re-started the nfs many times but still not work . thx
nfsnobody means its nfs mounted, with the secure default of root_squash option.
If you unmount it, you'll see the normal permissions/ownerships and be able to change it.
I assume you're on the nfs server here.
