in FAQ: edtFTPj/Free by (120 points)

I'm experiencing problems with edtFTPj, deployed on AWS: regardless of what settings I set in advanced connection/server settings I'm getting "Error: Server returned unroutable private IP address in PASV reply " testing my server with https://ftptest.net/ and in server logs I see:

where 172.31.30.187 is mu EC2 instance's private IP.

 

in code:

            ftp.setRemoteHost(AppConstants.FTPServer.HOST);
            ftp.setRemotePort(AppConstants.FTPServer.PORT);
            ftp.setUserName(username);
            ftp.setPassword(password);
      ftp.getAdvancedFTPSettings().setActiveIPAddress(AppConstants.FTPServer.HOST);
            ftp.getAdvancedFTPSettings().setConnectMode(FTPConnectMode.PASV);
            ftp.getAdvancedFTPSettings().setAutoPassiveIPSubstitution(true); // AWS has problems with this
            ftp.getAdvancedFTPSettings().setActivePortRange(3000, 4000);

 

where AppConstants.FTPServer.HOST value in my public IP, I'm 100% sure with logs.

 

What I do wrong and how to fix this?

Setting setAutoPassiveIPSubstitution(true) should work - what problem does AWS have with this?
by (120 points)
As you can see I have it set to true - edt seems to ignore this, returns private IP. I use free version 2.4.0 . Please disregard the comment concerning AWS has problems, it was about port range shall be opened.

Enable debug logging and post a small segment of the log file at the debug level.

here's the small piece around the passive mode host set to private:

here's the full log after server restart (pretty big, sorry - you might need it) https://www.dropbox.com/s/39px7wp3xse2gcm/PixelapCoreServer.log?dl=0

We need the edtFTPj log, not the server log.
by (120 points)
clientside log you mean? The logs I've attached are serverside including edtFTPj lib log.
here's what ftptest.net shows:

See here for how to enable logging in edtFTPj

http://enterprisedt.com/products/edtftpj/doc/manual/html/howtosetuplogging.html

The client cannot influence the IP address returned by the server in the PASV command. Instead, it should substitute it with the IP it used to connect.

None of this logging looks familiar. Where's the logging outputted by edtFTPj?
by (120 points)
I've set -Dedtftp.log.level=DEBUG to my Tomcat's JAVA_OPTS so it suppose to turn logging on. What would be the marks showing I'm getting edt logs?
Please note I have lines like
2016-04-20 13:24:06 INFO  FtpLoggingFilter:157 - SENT: 227 Entering Passive Mode (172,31,30,187,177,161)
on my logs. These are edt classes logs, right?
by (2.7k points)
This is not logging from edtFTPj.  Apache Mina is mentioned in the stack-trace and I suspect all of the logging is from there.   Mina seems to contain an FTP server.  edtFTPj is an FTP client library.
by (120 points)
Please say what is filter/mark for edtFTPj logs, please?
There are definitely fpt-related:

Oh! I think I got you! It's probably related to http://stackoverflow.com/questions/21015542/using-apache-ftp-server-in-passive-mode-not-working-connection-refused-by-serv described here. But I'm not implementing apache's server on my own, I use the default they provide. Will continue digging.
