A network file server can control which files are available for sharing. A network file server can also control which clients have access to the files, and what type of access is permitted for those clients. In general, the file server can grant read-write access or read-only access either to all clients or to specific clients. Access control is specified when resources are made available with the share command.
The /etc/dfs/dfstab file on the file server lists the file systems that the server makes available to clients on the network. For more information about sharing file systems, see Automatic File System Sharing in System Administration Guide: Network Services.
