Emmanuel Lécharny resolved FTPSERVER-327.
-----------------------------------------
Resolution: Invalid
"125 FTP Response code:
The server *may* use this code in response to a command initiating a file
transfer *if* the data connection is already established"
So there is no obligation to send a 125 reply before the 150.
> breaking RFC by replying 150 after establishing data connection

> Hi,
> RFC 959 explains 125 and 150 (valid intermediate responses for STOR/RETR) as
> follows:
> 125 Data connection already open; transfer starting.
> 150 File status okay; about to open data connection.
> If the data connection is already estabilished and after it the server
> receives STOR/RETR then it should respond with 125. I connected in passive
> mode using my custom client to verify this. I first estabilished a data
> channel and after it only I sent STOR but still got 150 which is wrong.
> Following is part of my code :
> data = new Socket(pasv_ip, pasv_port);
> data_os = data.getOutputStream();
> data_is = data.getInputStream();
> control_os.print("STOR " + "file.txt" + "\r\n");
> System.out.print("---> STOR " + "file.txt" + "\n");
> control_os.flush();
> System.out.println(control_is.readLine());
> However if I tried sending STOR before establishing data channel then also I
> received 150 which seems ok as per RFC.
