What is FTP over SSL (FTPS)?
FTP over SSL (FTPS or FTP/SSL) is an Internet standard FTP done over a secure SSL (Secure Socket Layer) TCP/IP connection to provide security and encryption. Secure FTP from the CornellC mainframe MVS system is done using TLS (Transport Layer Security) to secure and encrypt the FTP control and data connections. TLS is the latest version of SSL. Earlier versions of SSL are also supported. Use the MVS FTP client to connect to an FTPS server running on a Windows or Unix server.
An SSL certificate for your Windows or Unix server may need to be installed on the mainframe MVS system. If you have questions about FTPS servers or the TLS/SSL FTP setup, send e-mail to mainframesystems@cornell.edu.
Client Setup on a CIT Managed Server (Sending Files to the Enterprise Server)
- On managed Unix servers by customer request, CIT will install LFTP.
- On managed Windows servers, FileZilla is the CIT-supported FTP over SSL software. For information on installing FileZilla and transferring files, see File Transfer Using FileZilla.
Server Setup on a CIT Managed Server (Receiving Files from the Enterprise Server)
- By customer request on managed Unix servers, CIT will install ProFTP.
- By customer request on managed Windows servers, CIT will install FileZilla Client Server.
