Network File System(NFS)

Network File System
Among the many different file systems that Linux supports is the Network File System, also known as NFS. NFS allows a system to share directories and files with others over a network. By using NFS, users and programs can access files on remote systems almost as if they were local files.

* There is no need for users to have separate home directories on every network machine. Home directories could be set up on the NFS server and made available throughout the network.

The server has to be running the following daemons:

* nfsd The NFS daemon which services requests from the NFS clients.
* mountd The NFS mount daemon which carries out the requests that nfsd passes on to it.
* rpcbind This daemon allows NFS clients to discover which port the NFS server is using.

# NAS uses TCP/IP Networks: Ethernet, FDDI, ATM
