Secure FTP troubleshooting checklist

To troubleshoot problems with Secure FTP, use the following checklist:

  1. Make sure that the FTP server address and the port number are correctly configured in the session configuration.
  2. Check to make sure you are able to ping the FTP server.
  3. Check the status bar history for FTP commands and the server replies.
  4. Make sure that the server certificate is imported in the SSL keyring database file. Also, if client authentication is enabled, make sure that the client certificate is properly configured in the session configuration and a valid password is entered when asked.
  5. Check the SSL handshake flow by enabling FTPSession component trace level 2. The flow is traced to the Java Console by the SSL Package.
  6. Check the Security Troubleshooting Checklist, as most of the steps apply to secure FTP session as well.
  7. When connecting through a firewall, the control connection may break down or the data connection may time out. Refer to the IETF Internet-Draft FTP/TLS Friendly Firewalls at http://www.ietf.org for more information about running secured FTP through firewalls.
  8. Enable debug mode on the FTP server and run the test scenario. Check the trace data for errors.
