Retrieve files on the SCF by using SFTP/SCP, FTP or Hopper to make a copy of a file from the transfer server to your local machine. Initiate the FTP client software, connect to fastfis.llnl.gov, and complete the authentication process (by specifying a user name and SCF password). After you have connected to to fastfis.llnl.gov, change to your FROM directory and list the file(s) in the directory.


FTP (File Transfer Protocol) is an industry-standard protocol and user interface for transferring files between computer systems by means of a series of interactive commands. FTP involves a local client (software you execute to send or receive files) and a remote server (software elsewhere that responds to instructions from your client to accept or deliver files).

The Livermore Computing (LC) Identity Management (IdM) System automates the process of provisioning (creating and updating) and deprovisioning (deleting) user accounts across LC's multiple systems. IdM also allows the management of of accounts, groups, and LC identities for both the Open Computing Facility (OCF)—Collaboration Zone (CZ) and Restricted Zone (RZ)—and the Secure Computing Facility (SCF).

The Livermore Computing (LC) file interchange service (FIS) allows LC users to transfer files between the unclassified Open Computing Facility (OCF)—both the Collaboration Zone (CZ) and the Restricted Zone (RZ)—and the classified Secure Computing Facility (SCF). This document describes how FIS works and how to use it effectively.

New Account Setup outlines how to get an account on the Open Computing Facility (OCF) CZ and RZ systems and the Secure Computing Facility (SCF). You may also use the Livermore Computing (LC) Identity Management (IDM) System to request and manage accounts.
