Using SFTP/SCP at the GSD

FTP is no longer supported for connecting to terra. You must use SFTP/SCP.

SCP and SFTP are file transfer protocols that work similarly to FTP but run over an encrypted connection and are therefore much more secure. You can SCP/SFTP and connect to your terra account from anywhere in the world. For most purposes, SFTP and SCP can be thought of as being the same thing. The WinSCP site provides a detailed comparison.

Anyone with a GSD account transfer files using the these instructions. However, sometimes a person without a GSD account needs to transfer files here. In that case, contact helpdesk for access to a guest account. Never share your GSD account with others!

Tips

  • Depending on what is available in the SFTP software you use, choose SFTP with SCP fallback, SFTP, or SCP as connection type.
  • The first time you go to a new location, the program may ask you if it should cache the server key -- click yes.
  • A good way to share files with people is to stash the files in a web accessible part of your home directory (i.e. public_html or aux_nobackup) and then send them a URL so they can access the file in a web browser. This is simple and effective, provided that the files are not extremely large (multiple gigabytes) and do not need to be encrypted for privacy.
