Early Warning Reporting - EWR Data File Transfer Using PSFTP


All supported EWR file types may be submitted using one of the Artemis Secure FTP (SFTP) Servers. To submit aggregate, Death and Injury, and Substantially Similar Vehicle (SSV) data, use the Artemis SFTP server (DNS name: ARTSFTP.ODI.NHTSA.DOT.GOV). Use the secure field report server (DNS name: ARTFRSFTP.ODI.NHTSA.DOT.GOV) to submit field reports. This is the recommended method.

NOTE: If you send your file to the wrong SFTP server (for example, you submit an aggregate data file to the field report server), your submission will be rejected.

There are many applications that you can use to connect and transfer to the SFTP server. You must however, use the Secure Shell (SSH) 2 protocol. SSH (Secure Shell) is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over unsecured channels. It is intended as a replacement for rlogin, rsh, and rcp.

One of the applications that has been tested for use with Artemis is the PuTTY Secure File Transfer (PSFTP) client. PSFTP is a command line tool that you can use to transfer your Early Warning Reporting (EWR) files to the Secure FTP (SFTP) server. PSFTP is a free product that you can download from the Internet that uses the SSH 2 protocol.

    For submission of field reports, the Hostname is ARTFRSFTP.ODI.NHTSA.DOT.GOV.
    and press Enter. The "Login As:" prompt appears.

    • drivename is the local drive where the file directory is located (for example c:\).
    • "Path to File" is the directory where the EWR file is located. If the directory contains more than one word separated by spaces, you must use double quotes around the path name (for example "My Documents").
    • filename is the name of your EWR file.
