Jmeter FTP request in passive mode

Question

I am sending an FTP request using Jmeter. I just set the IP address and the jmeter in default send the file on port 21 and the server does not accept the file. But I want the process be passive which means the client negotiate with the server and after assigning a port number the file be sent on that.
How should I set it in Jmeter?
Also I have read this post which says the default mode is passive but it is not true for my case.

Answer 1

• JMeter establishes connection with the FTP server on port 21 (command channel). If your server is listening on the different port - use Port Number input to configure it.

  

• JMeter is configured to use local passive mode as it evidenced by the next line:

   ftp.enterLocalPassiveMode();// should probably come from the setup dialog        
  

  in the FTPSampler source code

• FTP server should tell JMeter a higher port for the data channel for file transfer

Assuming you

1. Provide path to existing local file
2. Tick put(STOR) box
3. If your file is not text-based tick Use Binary mode
4. Provide correct destination and credentials

you should be able to upload the file successfully. If you experience problems - implement the upload request using JSR223 Sampler and Apache Commons Net FTP libraries and enable debug logging to see where exactly your problem is.

If you are not able to establish the connection with the FTP server on port 21 - you won't be able to proceed.
