UCAR External Access

UCAR External Access
Prev	Chapter 2. Requirements and Restrictions	Next

Access from outside the UCAR security perimeter has additional restrictions. Please read this section carefully.

You must use an FTP Client that is compatible with the "Securing FTP with TLS" draft standard (RFC 4217). This defines how to use the TLS or SSL protocol to secure the FTP control connection. See Chapter 7, Compatible TLS-enabled FTP Clients for information on some compatible FTP Clients.
The FTP Client must secure the control connection with an AUTH TLS or AUTH SSL command before it sends the user name (USER) and password (PASS).
The FTP Client must be able to handle a data connection with no security beyond the default level (PROT C). FTP Clients that insist on securing both the control and data connections will not work.
