It may be possible that there is a bug in the FTPSClient impl - can you
post a transcript of the FTP commands and responses sent over the wire?
I've now tested this with FtpServer and I think I got a clue as to what
is going on. But, I would like to confirm my suspicions with you :-) I'm
CCing the FtpServer list on the discussion.
When using the PROT P command in active mode, the FTP server will try to
connect using SSL to the client. In this case the server acts as the SSL
client. However, this seems to fail and we get a cleartext data
connection. My feeling is that this is because the commons-net
SSLContext does not set a keystore it can't act as a SSL server.
However, I haven't tested patching FTPSClient yet so I'm not sure.
If I run in passive mode (where the FTPSClient will act as a SSL client
and FtpServer as a SSL server also for the data connection) everything
seems to work as expected.
You can find my simple test case here:
http://svn.apache.org/repos/asf/incubator/ftpserver/ssl-tests/trunk/src/test/org/apache/ftpserver/ssl/DataConnectionTest.java
Note that this tests differs from what Susanne described as I get a into
problems on a single STOR. This might be because I have some basic
misconfiguration, is so feel free to point me the right way :-)
