NFS Client Networking  «Prev  Next»
Lesson 6

NFS Client RPC Protocol Conclusion

NFS is useful when you want to have a central location for a group of files or you want to make file storage and software upgrading easier and more robust. For example, you know how to configure clients to use an NFS volume for their /home directory structure. This is certainly not the limit of NFS's capabilities; you can also organize NFS volume sharing to centralize information for many purposes. The mount options allow you to configure NFS's timeout parameter and make your NFS communications efficient by setting the read and write block sizes.
You also learned about the RPC protocol that facilitates communications for NFS and other network protocols. Remote Procedure Calls also provide a layer of transparency, hiding the source of remote information from user applications.

Learning objectives

Having completed this module, you should now be able to:
  1. Describe the NFS
  2. Define and explain RPC
  3. Use the mount command to access NFS shares
  4. Use /etc/fstab to automate the NFS client-side mounts

Glossary terms

The following terms were introduced in this module:
  1. Mount: To create a link from a directory name in the root hierarchy to a source of information. Sources of information include hard-disks, CD-ROMs, floppies, and drives on networked computers.
  2. Network File System: A protocol that uses remote procedure calls to mount remote drives to the local filesystem.
  3. Remote Procedure Call: A protocol through which applications receive information over a network without explicit knowledge of the network.
The next module covers system processes.
