You can start and stop client sessions, transfer and receive files, as well as set up File Transfer Protocol (FTP) batch jobs.
The FTP client allows you to transfer files that are found on your iSeries™ server, including those in the Root, QSYS.Lib, QOpenSys, QOPT, and QFileSvr.400 file systems. It also allows you to transfer folders and documents in the document library services (QDLS) file system. The FTP client can be run interactively in an unattended batch mode where client subcommands are read from a file and the responses to these subcommands are written to a file. It also includes other features for manipulating files on your system.
The client has a user interface from which you can enter client subcommands for making requests to an FTP server. The results of these requests are then displayed.
To transfer files between the client and the server, two connections are established. The control connection is used to request services from the server with FTP server commands. The server sends replies back to the client to indicate how the request was handled. The second connection, called the data connection, is used for transferring lists of files and the actual file data.
Both the client and the server have a data transfer function that interfaces to the resident file systems. These functions read or write data to the local file systems and to and from the data connection.
