FTP returns 150 instead of code/message for "port is disabled"
--------------------------------------------------------------
Key: FTPSERVER-110
URL: https://issues.apache.org/jira/browse/FTPSERVER-110
Project: FtpServer
Issue Type: Bug
Components: Core
Reporter: Rico Neubauer
If using pasive mode and active mode is disabled the "PORT" command is answered
with "510 port is disabled".
However if you go on with the next command ("LIST"), then the FTPServer answers
"150 ..." instead of "510 PORT command disabled before LIST") or
some similiar descriptive error. Also the it is tried to open the active port
and a 425 is sent:
