<h3>Introduction to NFS</h3>
|
|
|
|
NFS is the standard file-sharing protocol used by Unix systems. NFS allows
|
|
one system to export a directory across the network to one or more other
|
|
hosts, allowing users and programs on those hosts to access exported files
|
|
as though they were local. <p>
|
|
|
|
An NFS server is a system which exports one or more directories, while an NFS
|
|
client is a system that mounts one or more directories from a server. A
|
|
host can be both an NFS server and a client of other servers. <p>
|
|
|
|
A server controls which clients can mount an exported directory by checking
|
|
the IP address of the client against a list of allowed hosts for the
|
|
requested directory. The server can also designate an export read-only,
|
|
or read-only for certain clients. <p>
|
|
|
|
Unlike other network filesystems, an NFS client does not have to login to
|
|
the server when mounting an exported directory. The server trusts the client
|
|
to authenticate users and provide the ID of the current user when accessing
|
|
exported files. Thus you should only allow client hosts that you trust to
|
|
mount exported directories. <p>
