Working with the Network File System

Objectives

• Describe the Network File System
• Export and import file systems in Ubuntu
• Identify key NFS services
• Edit NFS configuration files to export and import network file systems manually

An Overview of the Network File System

Network File System (NFS)

• A distributed file system protocol for allowing remote access to shared resources across networks
• You can mount shared file systems on remote machines Mount
  • Term for making files appear as though they’re on a local machine instead of on a remote machine
  • Similar to drive mapping in Windows

Remote Procedure Calls

Remote Procedure Calls (RPC) is a protocol that allows one network computer to request a service from a program on another network computer. NFS relies on RPC to route requests between NFS server and client

Exporting File Systems in Ubuntu

NFS server

• A Linux network computer that exports directories to all networked hosts that have access to it Installing NFS Server software
• Start Terminal and type the following command: sudo apt install nfs-kernel-server

Importing File Systems in Ubuntu

Ensure that nfs-common is installed (command below): sudo apt install nfs-common
