Following are changes introduced in this release that are of interest to the administrator of the VM NFS server machine.

• If you have users who access public minidisks (anonymous access) when using an External Security Manager: You may need to define a user ID of ANONYMOU for the system when you move to Function Level 320. See Appendix A. Using TCP/IP with an External Security Manager in the TCP/IP Function Level 320 Planning and Customization book for more information.

• You can configure EXPORT strings to allow Windows® users, for example, to use point and click to get access to VM file systems. EXPORTed file systems can include 'wildcards' for user ID, BFS root, and BFS initial working directory.

• More of the VM NFS server machine's parameters are tailorable, and you can refresh server configuration parameters without stopping the server.

• Security is enhanced.
  • The ANONYMOUS DTCPARMS or start-up parameter also applies to minidisk MOUNTs.

  • A new exit, VMNFSSMG, screens all SMSG requests.

  • The VMNFSMON exit is improved to handle new MOUNT options.

  • You can configure whether mounts should be restricted to exported file systems only.

  • You can configure whether or not the server should provide a list of mounted file systems.

• More detailed tracing is available with the use of the MASK start-up or SMSG command. Increased subsetting of trace information is also possible.

• New start-up parameters allow you to restrict the server to the Version 2 NFS level and UDP communications.
