For transfers between your local host and NAS systems, the transfer must be initiated from your local host with shiftc invoked via the SUP client (that is, using the command sup shiftc). Shift can be used as a drop-in replacement for scp between any enclave systems. Shift is the recommended method for transferring files to and from the Lou mass storage system, as it can create tar files as part of the transfer and split a transfer into multiple tar files for oversized directories (larger than 1 TB). Do you need it installed on your local host?įor transfers between your local host and NAS systems, you must install the SUP client as discussed in Shift File Transfer Overview. Shift is installed on Lou and on the PFEs. Shift utilizes a variety of underlying file transports to achieve maximum performance for files of any size on any file system. Shift ( shiftc) is a NAS-developed tool for performing automated local and remote file transfers. We recommend using OpenSSH 5.0 or a newer version. If your data will compress well, consider enabling compression by adding -C to your scp command line. Within the NAS secure enclave, depending on source and destination hosts and other factors, the performance range will be 40-100 MB/sec. Note: Due to formatting issues, the command line in the above example is shown on two lines. file2įor inbound transfer if SSH passthrough has been set up correctly: your_localhost% scp file1 file2įor inbound transfer if you have not set up SSH passthrough: your_localhost% scp -oProx圜ommand=' ssh %h' file1 file2 ![]() These examples assume you already know how to log into the NAS enclave.įor outbound transfer: lou% scp your_localhost.domain:file1. Note: Omit and in the examples below if your local username and NAS username are identical. "Inbound" means the command is initiated on your local host. In these examples, "outbound" means the command is initiated on a NAS host such as Pleiades or Lou, whether the file is being pushed or pulled. Typically, scp is used to transfer small files within NAS (<< 5 GB) or offsite (<< 1 GB) that take a reasonable amount of time to complete. If you have a version of SSH installed on your local host, scp is most likely already installed there. Do you need it installed on your local host? Where is scp installed at NAS?Ī copy of scp from OpenSSH without the patch is available on the Pleiades front-end systems (PFEs), Lou, and the secure front-end systems ( SFEs). The most widely used scp program is from OpenSSH. Both your authentication information (such as password or passcode) and your data are encrypted. The Secure Copy Protocol ( scp) command, based on the Secure Shell Protocol ( SSH), is a means of securely transferring files between a local and a remote host. Use the file transfer commands scp or shiftc when the source and destination are located on different hosts-either on two different NAS high-end computing hosts, or on a NAS host and a remote host such as your local desktop system.
