> Hi,
> With Pure-FTPd, commons-net3.5, and FTPES (explicit TLS) I get "Connection
> closed without indication."
> I have found some old bug with similar behaviour:
> https://issues.apache.org/jira/browse/NET-354
> I have run the CCCTester.java:
> https://issues.apache.org/jira/secure/attachment/12476247/CCCTester.java
> with some minor changes:
> ftps = new FTPSClient("TLS", false);
> ....
> ftps.enterLocalPassiveMode();
> if (!FTPReply.isPositiveCompletion(ftps.getReplyCode()))
> throw new FTPException(FTPException.kPassiveModeRefused);
> .....
> int port = 21;
> This is the output:
