public class FtpsServer extends FtpServer implements FtpConstants
FtpServer. It implements the FTPS protocol as defined
in Securing FTP with TLS specification,
which is based on RFC 2228, FTP Security Extensions.
FTPS protocol defines a mechanism for securing the control and data connections of a FTP session. FTPS uses SSL to provide a
confidential, and integrity protected channel. We support two flavors of FTPS. Implicit FTPS secures the channel on
connection. Explicit FTPS secures the connection when the client issues an AUTH command.
An Explicit FTPS connection starts out as a regular FTP connection. The connection is secure only after the client issues an AUTH command. Server Implementations are free to define their Security policy, which controls what a client can do before the channel is secure. At least for the initial release we have defined a very strict policy, that is not configurable.
Several aspects of the SSL Context are configurable. See SocketFactory
for details. Again, we will mostly use the defaults, and provide little or no configurability in the first release.
Architecturally, we have refactored the FtpServer to allow:
getServerSocketFactory method that is called during establishing the Server Socket.
FtpsServer overrides this method to create an SSLServerSocket if needed.
ServerChannel can be ovverriden by changing the
createChannel method. FtpsServer, creates a FtpsServerChannel.
This class changes the way Data Sockets are created, and enforces the Security policy of the Connection.
AUTH,
PROT, PBSZ,
and CCC.
IFS.SERVER.PROTOCOL.FTPS.SECURITY.IMPLICIT which
controls whether the FtpsServer supports the Implcit or Explicit FTPS protocol. The default value is false.
