Answer 1

The FTP server is Rumpus v 7.2.3 from Maxum (http://www.maxum.com/Rumpus).

It is running on a Mac mini (Late 2006) using Mac OS X Server 10.5.8

Answer 2

The message is "USER and PASS required first" in response to PROT.

So it looks to me as though it requires AUTH, then USER/PASS, and then PSBZ0 and PROT P, e.g.

ftp.setConfigFlags(SSLFTPClient.ConfigFlags.START_WITH_CLEAR_DATA_CHANNELS);
ftp.setValidateServer(false);
ftp.connect();
ftp.auth(SSLFTPClient.AUTH_SSL);
ftp.login(username, password);
ftp.pbsz(0);
ftp.prot(SSLFTPClient.PROT_PRIVATE);
