About managing NFS shares using netgroups
A netgroup defines a network-wide group of hosts and users. You use netgroups for restricting access to shared NFS file systems and to restrict remote login and shell access.
Each line in the netgroup file consists of a netgroup name followed by a list of members, where a member is either another netgroup name, or a comma-separated list of host, user, or a domain. Host, user, and domain are character strings for the corresponding components. Any of these three fields can be empty, which indicates a wildcard, or may consist of the string "-" to indicate that there is no valid value for the field. The domain field must either be the local domain name or empty for the netgroup entry to be used. This field does not limit the netgroup or provide any security. The domain field refers to the domain in which the host is valid, not the domain containing the trusted host.
When exporting a directory by NFS with the specified options, clients may be specified using netgroups. Netgroups are identified using @group. Only the host part of each netgroup member is considered when checking for membership.
