NiFi ListenFTP Processor Default Data Port

Question

What is the default port used by the Apache NiFi processor ListenFTP for the data channel in active FTP mode? For the control channel the default port is 2221. Is the default port for the data channel in active mode 2220?

The default ports for FTP are 21 for control channel and 20 for data channel. Because ports below 1024 require root access, the NiFi default port for control channel is 2221.

Under the cover this is just using Apache FTP Server

Depends on passive ports

Send is over passive

An example is here
