Sebb commented on FTPSERVER-414:
--------------------------------
The format of the output looks correct, however according to the RFC 959 the
status code should be one of
STAT
211, 212, 213
450
500, 501, 502, 421, 530
where
211 System status, or system help reply.
212 Directory status.
213 File status.
200 is not a valid reply status, as far as I can tell
> STAT / creates invalid directory listing (with Patch)

> Key: FTPSERVER-414
> URL: https://issues.apache.org/jira/browse/FTPSERVER-414
> Project: FtpServer
> Issue Type: Bug
> Components: Server
> Affects Versions: 1.0.5
> Reporter: Emmeran Seehuber
>
> Some ftp clients (e.g. Cyberduck on Mac OS X) use the STAT command to list
> directores. The reply contains an invalid status code in the last line, which
> causes the ftp client to ignore the last line. So the last file in the
> directory does not show up in the ftp client listing:
> 614869 [pool-3-thread-6] INFO

> 615085 [pool-3-thread-6] INFO

> I dont know if this is a bug in the ftp client. But at least the following
