When my customers are trying to transfer the files through ftp system, they are getting this error. It seems like the ftp connection is established however because of some unknown reasons the data is not transferring. This is a connection from VMS system to a Unix server.

  • [FTP](https://en.wikipedia.org/wiki/File_Transfer_Protocol) uses two ports. The first, port 21, is used to establish a connection between the client and server and transfers command and status information. The second is used to transfer data and the connection is established when a file transfer is initiated. It appears that the server is refusing to establish the data connection. Perhaps the log on the server offers a clue, e.g. it doesn't care for the client's address, the transfer type (ASCII vs. binary), the transfer mode (active vs. passive), ... . – HABO Sep 23 '14 at 15:58
  • Using google "Command Prompt uses Active mode by default. As you are able to log in (port 21), but not issue commands, it would seem you are not able to establish the Data connection which, using active mode would mean you would have to have a random port open on your firewall to connect to the server's data port of 20." try passive mode? Send: quote pasv – Hein Sep 23 '14 at 20:46
  • Thank you folks...moving to passive mode worked – jis1729 Sep 24 '14 at 17:27

If you use VMS FTP then use:

set passive on

before you start the data connection.

If you use VMS COPY /FTP then use:

copy /ftp/passive

to use passive mode.

For more information, see 

ftp> help set passive

and 

$ help copy /ftp
