Please Whitelist This Site? I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :) If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads. If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK. Thanks for your understanding! Sincerely, Charles Kozierok Author and Publisher, The TCP/IP Guide

DNS Changes To Support IP Version 6 1 Overview of File and Resource Sharing Protocol Concepts and Operation

To the typical end user, networks were created for one main reason: to permit the sharing of information. Most information on computers exists in the form of files that reside on storage devices such as hard disks; thus, one primary purpose of networks is to let users share files. File transfer and message transfer protocols exist that allow users to “manually” move files from one place to the next, but a more automated method is preferable in many cases. Internetworking protocols provide such capabilities in the form of network file and resource sharing protocols.

In this section, I provide a description of network file and resource sharing protocols from the standpoint of TCP/IP networks. I begin with a brief overview of the concepts and operation of this class of protocols, discussing some of the elements common to the different types. I then describe the most common one defined specifically for TCP/IP: the Network File System (NFS).
