For demonstrations is this chapter, we will use two virtual machines running in an Oracle VirtualBox virtualization environment. VirtualBox can be downloaded from https://www.virtualbox.org/ free of charge and is available for Windows, Mac OS X, Linux, and Solaris hosts.

The NFS Server will be configured on the RHEL 7.1 host with the IP address of 192.168.10.10 and the hostname of nfshost. The NFS client will be configured on the RHEL 7.1 host with the IP address of 192.168.10.11 and the hostname of nfsclient.
