--------------------------------

             Summary: Check Pure-FTPd FTPES (explicit TLS)
                 Key: NET-598
                 URL: https://issues.apache.org/jira/browse/NET-598
             Project: Commons Net
          Issue Type: Task
          Components: FTP
    Affects Versions: 3.5
            Reporter: Stefan Matei
             Fix For: 3.5


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:

REPLY: 220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
220-You are user number 1 of 50 allowed.
220-Local time is now 02:28. Server port: 21.
