shared directory.</p><p>NFS clients may be specified in a number of ways:</p><p><span class="emphasis"><em>single host</em></span>: a host either by an abbreviated
name recognized be the resolver, fully qualified domain name, or an IP
address</p><p><span class="emphasis"><em>netgroups</em></span>: NIS netgroups may be given as
@group.</p><p><span class="emphasis"><em>wildcards</em></span>: machine names may contain the
wildcard characters * and ?. For instance: *.cs.foo.edu matches all
hosts in the domain cs.foo.edu.</p><p><span class="emphasis"><em>IP networks</em></span>: you can also export directories
to all hosts on an IP (sub-)network simultaneously. For example, either
`/255.255.252.0' or `/22' appended to the network base address.</p></div><div class="section" title="User ID Mapping"><div class="titlepage"><div><div><h5 class="title"><a id="d4e2169"><!----></a>User ID Mapping</h5></div></div></div><p><span class="emphasis"><em>map root user as anonymous</em></span>: maps requests
from uid/gid 0 to the anonymous uid/gid (root_squash). The root user
from the client cannot read or write to the files on the server which
are created by root on the server itself.</p><p><span class="emphasis"><em>allow real remote root access</em></span>: turn off root
squashing. This option is mainly useful for diskless clients
(no_root_squash).</p><p><span class="emphasis"><em>map all users to anonymous user</em></span>: maps all
uids and gids to the anonymous user (all_squash). Useful for
NFS-exported public FTP directories, news spool directories, etc. The
opposite option is no user UID mapping (no_all_squash), which is the
default setting.</p><p><span class="emphasis"><em>anonuid and anongid</em></span>: explicitly set the uid

requests originate on an internet port less than IPPORT_RESERVED (1024).
This option is on by default.</p><p><span class="emphasis"><em>Read-Only share</em></span>: allow either only read or
both read and write requests on this NFS volume. The default is to
disallow any request which changes the filesystem. This can also be made
explicit by using this option.</p><p><span class="emphasis"><em>Synchronous access</em></span>: prevents the NFS server
from violating the NFS protocol and to reply to requests before any
changes made by these requests have been committed to stable storage
(e.g. disc drive).</p><p><span class="emphasis"><em>Subtree checking</em></span>: enable subtree checking
which can help improve security in some cases, but can decrease
reliability.
