If you want to use OSI applications over TCP/IP and/or DECnet over TCP/IP, invoke NET$CONFIGURE with the ADVANCED option, and select Option 4 ("Configure Transports") to configure (or reconfigure) the OSI transport. You can then create a new OSI transport NCL script (or replace the old script). You must also include Domain in your Session Control naming search path by selecting Option 2 to rename your node. This is described in Section 2 of the Applications Installation and Advanced Configuration Manual. For the changes to take effect, either disable the OSI transport entity (if it exists) and invoke the new OSI transport NCL script, or reboot the system. NCL> disable osi transport NCL> do sys$manager:net$osi_transport_startup.ncl Also, ensure that TCP/IP is started on the node and that the PWIP driver is loaded. When configuring RFC 1006, RFC 1859, or both, each element in the OSI transport entity's set of RFC 1006 listener ports attribute corresponds to a TCP listener port. By default, NET$CONFIGURE sets the OSI transport RFC 1006 listener ports attribute to { 102, 399 }. Port 102 is required for RFC 1006, and port 399 is required for RFC 1859.
