Inside Linux The mapping options are given in (Web site layout)
Inside Linux The mapping options are given in the parentheses, such as rw and insecure. A hostname can be prefixed to the option, thereby associating the option to the host. Table 12.2 lists the available mapping options. Table 12.2. Mapping Options for the /etc/exports File Option Description root_squash This option is a security feature denying the super user on the specified hosts any access rights; it does this by mapping requests from uid 0 on the client to uid 65534 (should be associated with the user nobody) on the server. This does not apply to uids that might be as sensitive, such as bin. no_root_squash This option turns off root squashing. Mainly used for diskless clients. squash_uids and squash_gids This option specifies a list of uids (or gids) that are subject to anonymous mapping. A valid list of IDs looks like squash_uids=0 15,20,25 50 all_squash This option is used to map all uids and gids to the anonymous user. Useful for NFS-exported public FTP directories, news spool directories, and so on. map_daemon This option turns on dynamic uid and gid mapping. Each uid in an NFS request will be translated to the equivalent server uid, and each uid in an NFS reply will be mapped the other way round. map_static This option enables static mapping, specifying the name of the file that describes the uid/gid mapping: map_static=/etc/nfs/foobar.map. map_nis This option enables NIS-based uid and gid mapping. anonuid and anongid These options are used to explicitly set the uid and gid of the anonymous account. This is useful for PC/NFS clients, in which you might want all requests to appear to be from one user. You can specify the NFS clients in several ways. Table 12.3 shows the various formats. Table 12.3. NFS Client Formats Format Description single host Commonly used format. You can specify a host using an abbreviated name that is recognized by the resolver, a fully qualified domain name, or an IP address. netgroups NIS netgroups may be identified as @group. The host part of all netgroup members is extracted, and then added to the access list. wildcards The hostnames can contain the * and ? wildcard characters. Can be used to make the exports file more compact. Example: *.foo.edu matches all hosts in the foo.edu domain. However, these wildcards do not match dots in a domain name. Thus, the preceding pattern does not include hosts such as http://www.cs.foo.edu. IP networks Directories can be exported to all hosts on an IP (or sub) network simultaneously. You do this by specifying the IP address and netmask pair as address/netmask. If no machine name is given, any machine is allowed to import (or mount) the filesystem within the limits set by the options. If you have made any modifications to the /etc/exports file while the NFS system is running, you should shut down the daemons and restart them. page 218
