This page covers three ways to transfer files between your machine and the supercomputer:
- SCP: a command line tool for quickly copying a file or two
- Local mounting: mount remote storage so that you can browse files on the supercomputer as if they were on your own hard drive
- Dedicated GUIs: graphical programs designed specifically for moving files between local and remote storage
All the methods described run over ssh are are thus encrypted. Instructions for Windows, macOS, and Linux are included.
If you are interested in transferring files on the supercomputer to and from cloud storage, we recommend using rclone.
scp is useful when you know exactly where your file is and simply want to copy it to/from the supercomputer. To do so, open a terminal/command prompt and enter something like (replacing
username with your username, of course):
# From supercomputer to local computer: scp firstname.lastname@example.org:/fslhome/username/myfile.txt Documents/ # From local computer to supercomputer: scp Documents/myfile.txt email@example.com:/fslhome/username/
If you want to browse files on the supercomputer using your file manager, you can use SSHFS (macOS/Linux) or SFTP Net Drive (Windows). This allows you to transparently interact with the files there as if they were on your local machine--you could open a remote text file with Notepad, or save the csv file you're working on in Excel directly to the supercomputer.
sshfs allows you to mount supercomputer storage locally from the command line. For Linux, install sshfs with your package manager if it isn't included; for macOS, download FUSE and SSHFS here. To mount the supercomputer storage, open a terminal, choose an empty directory (called
sc for the sake of this example), and use the following:
# For Linux: sudo sshfs -o allow_other,follow_symlinks \ firstname.lastname@example.org:/fslhome/username sc # For macOS: sudo sshfs -o allow_other,follow_symlinks,defer_permissions \ email@example.com:/fslhome/username sc
After entering your password and verification code, you should be able to navigate to
sc in Finder/Nautilus/Dolphin/Thunar/etc. and view files on the supercomputer.
To unmount, use
sudo umount sc.
- Profile: create a new one
- Server: ssh.rc.byu.edu
- Username: your username
- Authentication: Keyboard-interactive
- Drive Letter: the default ("Last Available") works
Upon pressing "Connect" you will be asked for your password and verification code, and File Explorer will open to your supercomputer storage.
As of the writing of this article, one can't use
sshfs within the Windows Subsystem for Linux and SSHFS-Win still doesn't work with two-factor authentication, so SFTP Net Drive seems to be the only simple way to mount remote storage on Windows.
Most programs that are specifically designed for transferring files between local and remote storage work somewhat like Norton Commander, with one column for local storage and one column for remote storage to facilitate moving files between them. FileZilla works on all the major operating systems; to get it to behave more nicely, follow this guide (replacing addresses and usernames appropriately). If you are using Windows, WinSCP is a bit more intuitive and easy to set up than FileZilla. Cyberduck is also commonly used, but SSHFS or SFTP Net Drive in combination with your file manager achieves the same effect.
