4.1 FTP-Initiated Gateway Service

The FTP Client uses the FTP-Initiated gateway service to utilize the resources of an FTAM Responder.

To initiate a file transfer from an FTP Client, the Client connects to the FTP-Initiated gateway service via TCP/IP. The gateway then establishes a connection, via OSI, to the FTAM Responder. At this point, the user can initiate file transfer operations.

The FTP Client is responsible for providing the gateway with an authoritative Distinguished Name, or a User Friendly Name, of the desired OSI filestore. It is the responsibility of the gateway to resolve this Distinguished Name, or User Friendly Name, to its corresponding Presentation address.

The logon sequence taken by an FTP Client when initiating a file transfer with an FTAM Responder is given below:

          % ftp gateway          ftp> site Distinguished-Name-of-FTAM Responder          ftp> user username          ftp> pass password

The "ftp gateway" command initiates the connection between the FTP Client and the gateway. Once connected to the gateway, the FTP Client should identify the desired FTAM Responder service via the Responder's Distinguished Name, or User Friendly Name, which is resolved by an algorithm running on the Directory Services provider. This information is sent via a "site Distinguished-Name-of-FTAM Responder" or "site UFN-of-FTAM Responder" command.
