The Solaris 7 release includes extensions to the mount command and automountd command. The extensions enable the mount request to use the public file handle instead of the MOUNT protocol. The MOUNT protocol is the same access method that the WebNFS service uses. By circumventing the MOUNT protocol, the mount can occur through a firewall. Additionally, because fewer transactions need to occur between the server and the client, the mount should occur faster.
The extensions also enable NFS URLs to be used instead of the standard path name. Also, you can use the public option with the mount command and the automounter maps to force the use of the public file handle. See WebNFS Support for more information about changes to the WebNFS service.
