Chapter 5. Network File System

A Network File System (NFS) allows remote hosts to mount file systems over a network and interact with those file systems as though they are mounted locally. This enables system administrators to consolidate resources onto centralized servers on the network.[5]
In Red Hat Enterprise Linux, the nfs-utils package is required for full NFS support. Run the rpm -q nfs-utils command to see if the nfs-utils is installed. If it is not installed and you want to use NFS, run the following command as the root user to install it:
~]# yum install nfs-utils

5.1. NFS and SELinux

When running SELinux, the NFS daemons are confined by default. SELinux policy allows NFS to share files by default.
