LFTP¶

Tip

To use SFTP/LFTP, you will need to be connected to our file transfer nodes, hostname: filexfer.hpc.arizona.edu.

SFTP¶

SFTP (Secure File Transfer Protocol) ensures data encryption during transmission over the network. It offers features such as resuming interrupted transfers, directory listing, and remote file management.

To perform file transfers using SFTP, you'll need an SSH v2 compliant terminal. To connect to HPC's data transfer nodes, run:

sftp your_netid@filexfer.hpc.arizona.edu

You will then be able to move files between your machine and HPC using get and put commands. For example:

sftp> get /path/to/remote/file /path/to/local/directory ### Retrieves file from HPC. Omitting paths will default to working directories.
sftp> put /path/to/local/file /path/to/remote/directory ### Uploads a file from your local computer to HPC. Omitting paths will default to working directories.
sftp> help ### prints detailed sftp usage

FTP/LFTP¶

Warning

Due to security risks, it is not possible to FTP to the file transfer node from a remote machine, however, you may FTP from the file transfer node to a remote machine.

HPC uses the FTP client LFTP to transfer files between the file transfer node and remote machines. This can be done using get and put commands. To use lftp, you must first connect to our file transfer node using an SSH v2 compliant terminal:

ssh your_netid@filexfer.hpc.arizona.edu

Once connected, you may connect to the external host using the command lftp. For example:

lftp ftp.hostname.gov

You will then be able to move files between HPC and the remote host using get and put commands. For example:

> get /path/to/remote/file /path/to/local/directory ### retrieves file from remote host
> put /path/to/local/file /path/to/remote/directory ### Uploads file from HPC to remote host
