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

NFS File System Model and the Mount Protocol
(Page 3 of 3)

Mount Protocol Server Procedures

The actual implementation of the Mount protocol is very similar to that of NFS itself. Like NFS, the Mount protocol uses XDR to define data types to be exchanged between client and server, and RPC to define a set of server procedures that clients may use to perform different operations. The main difference between Mount and NFS is simply that Mount defines procedures related to opening and closing filesystems rather than file access operations. Table 185 shows the server procedures used in the Mount protocol.

Dummy procedure provided for testing purposes.

1

mnt

Add Mount Entry

Performs a mount operation by mapping a path on a server to a file handle for the client to use.

2

dump

Return Mount Entries

Returns a list of remotely mounted file systems.

3

umnt

Remove Mount Entry

Performs an “unmount” by removing a mount entry. (It should be “dismount”. Techies are rarely into grammar. J)

4

umntall

Remove All Mount Entries

Removes all mount entries, thus eliminating all mounted file systems between server and client.

5

export

Return Export List

Returns a list of exported file systems and indicates which clients are allowed to mount them. This is used to let the client see what served file systems are available for use.


As mentioned in other topics in this section, NFS version 4 does away with the notion of a separate Mount protocol, incorporating file mounting operations into NFS directly.
