Our FTP service is deprecated in favor of the UMIACS Object Store. Please see OBJ. Depending on when your account was installed, you may or may not have FTP access.

UMIACS provides FTP services for transferring data to external collaborators. Since the FTP protocol is conducted entirely in plaintext, external users login to the service as anonymous, and internal users can access the file directories internally. Users will never authenticate over FTP with their UMIACS account. Please see SFTP for more information on a secure file transfer protocol.

Publishing datasets via FTP

Users can place data to be externally accessible in their public FTP space, which is located from the FTP service as 

ftp://ftp.umiacs.umd.edu/pub/<username>/

To upload data to your public site, you can upload data to either

  • /fs/ftp/pub/<username> from supported UNIX machines
  • \\umiacs-webftp\ftp-umiacs\pub\<username> from supported Windows machines
