Uploading Digital Data to ITC   UPDATED (12/19/06)

Changes in ITC's network configuration have necessitated a transition from FTP to Secure FTP for all protocol participants uploading digital data to the ITC. Secure FTP (SFTP) uses the SSH network protocol and offers several advantages over FTP, including secure (encrypted) transport of usernames, passwords, and data, and compatibility with most firewall configurations.

Please note:

  • The old ITC FTP server (castor.wustl.edu) is no longer in service. All network digital data submisions to ITC must use the new, Secure FTP server, ITCsubmit.wustl.edu (IP address 128.252.17.87).
  • User names and passwords for SFTP are the same as those used for FTP.
  • Instructions for configuring SFTP clients (WS FTP Pro, Filezilla, WinSCP3, and Linux sftp)  UPDATED (6/14/06).
  • Problems in connecting to the ITC SFTP server, may be caused by your institution's firewall configuration. An outbound connection from your computer to TCP Port 22 on host ITCsubmit.wustl.edu is required. (Although allowing such a connection is safe, it is sometimes disallowed by default.)  Please consult your local firewall/network administrator.
  • For many users, the SFTP upload procedure is essentially the same as for FTP, except that a new SFTP client may be needed. SFTP client software, both commercial and open-source, is broadly available. Windows clients include WS_FTP Professional (commercial), FileZilla (free/open-source) and WinSCP (free/open-source). For Linux systems, both graphical (gftp) and command-line (sftp) programs are included with most distributions.

Please direct questions regarding digital data submission to Walter Bosch or John Matthews (itc@castor.wustl.edu).
