NFT

NFT (Network File Transport) is a file-transfer utility developed at LC and tailored to local needs. NFT features persistent, passwordless file transfer among worker machines and to the storage system in both the open and secure environments (with automatic routing of storage transfers through fast, jumbo-frame network connections where available). To monitor and confirm file transfers, NFT provides extensive job-tracking aids. It also supports command files and easy use in batch jobs.

This document is the comprehensive reference manual for NFT. Consult EZOUTPUT for a concise, task-oriented, introductory treatment of NFT that compares it with FTP. Consult EZSTORAGE for an overview of LC's archival storage system and of NFT's role in managing stored files (alternatives to NFT for storage management are also explained). The FTP Reference Manual tells how standard FTP features, including storage access, are implemented among LC production machines. If your file-transfer needs specifically involve placing many files into or retrieving them from a remote archive (TAR-format library) file, consult the HTAR Reference Manual for another LC-designed, locally deployed tool tailored to efficiently managing large archives in storage or on any preauthenticated FTP server. If you prefer a visual interface to NFT (where you select files and target directories with CTRL-CLICK using your mouse, for example), then execute HOPPER on any LC production machine and select NFT from HOPPER's CONNECT menu.

NFT runs on LC's open and secure Linux/CHAOS production machines.

Note that besides the open and secure archival storage systems, only those machines that support NFT clients also accept incoming file transfers using NFT. Other hosts (such as FIS) do not accept NFT transfers.
