Prior to running the PMDF-XGS configuration utility you must have installed PMDF-MTA with PMDF-XGS support. It is also strongly recommended that you have configured PMDF-MTA. Refer to Chapters 1--5 if you have not already installed and configured PMDF.

The PMDF-XGS configuration utility will prompt for several pieces of required information. You should be prepared to provide the following:

• The name by which the PMDF system will be known on the SNADS side. Each SNADS node must be configured to know about this name, so this name choice should be coordinated with whomever is going to do the configuration of the SNADS nodes, if that is a person other than yourself. Note that SNADS names cannot exceed eight characters.
• The names by which the PMDF-XGS transport bridge system will be known; it will be known by a TCP/IP name from the PMDF-MTA/PMDF-XGS side, and by a SNADS name from the SNADS side. Again note that each SNADS node must be configured to know the SNADS name of the PMDF-XGS transport bridge so this name choice should be coordinated with the person configuring the SNADS nodes. (As the PMDF-XGS transport bridge passes all SNADS distributions handed over by the SNADS side to the PMDF-MTA/PMDF-XGS system, one possibility is to give the PMDF-XGS transport bridge the same SNADS name as that used for the PMDF-MTA/PMDF-XGS system itself.)
• The TCP/IP port numbers that the PMDF-XGS transport bridge programs expect to use when communicating with the PMDF system, as configured in the xgs.cmd script on the PMDF-XGS transport bridge. These values are normally configured during the PMDF-XGS transport bridge installation; see Chapter 10 for details and Chapter 11 for an example.
• The SNADS name of the SNADS node immediately adjacent to the PMDF-XGS transport bridge, that is, the SNADS node through which all the SNADS distributions will be routed. You must know the SNADS REN name; providing the SNADS RGN name also is generally optional, although in some SNADS networks explicitly specifying the RGN name may provide a performance improvement.
• You will also be asked to assign a domain name to that SNADS node; this domain name is the name that will be used from the PMDF-MTA/PMDF-XGS system side to address the SNADS node. If you want to let other SMTP hosts send to the SNADS node through PMDF-XGS, then you will need to add an MX record to the DNS for the domain associated the SNADS node, so pick a suitable domain name.
• The SNADS name (REN) of every other SNADS node accessible through this gateway, and domain names of your choosing to associate with each such additional SNADS node.
• The domain names of any systems on the PMDF side for which the SNADS side will be configured to know the (truncated to eight characters, if longer) host name.
