The Solaris 2.6 release also included the ability to make a file system on the Internet accessible through firewalls. This capability was provided by using an extension to the NFS protocol. One of the advantages to using the WebNFSTM protocol for Internet access is its reliability. The service is built as an extension of the NFS version 3 and version 2 protocol. Additionally, the WebNFS implementation provides the ability to share these files without the administrative overhead of an anonymous ftp site. See Security Negotiation for the WebNFS Service for a description of more changes that are related to the WebNFS service. See WebNFS Administration Tasks for more task information.
The NFS version 4 protocol is preferred over the WebNFS service. NFS version 4 fully integrates all the security negotiation that was added to the MOUNT protocol and the WebNFS service.
