Description (partial)

FTP control and data connections appear in ESTAB state in the output of sh tcp br all after copying a zero byte file. This would usually appear for a time period of 2-3 mins after the completion of the copy operation.
Also, in case of a non-zero byte file copy tracebacks appear when doing active ftp, though the copy operation is successful.

"no ip ftp passive" should be configured to enable active ftp.
