com.enterprisedt.net.ftp.FTPException: 500 Illegal PORT comm

I am using edtftpj 2.2.2 APis and is running into following exception. I am able to connect to the host and list directory using "ftp" program. I have replaced the ipAddress of my host with <myHost>

[support2]

use ftp.getAdvancedFTPSettings().setActiveIPAddress("<host ip>")

from the logs ------ PORT 10,172,154,82,234,128

10.172.154.82 is the correct IP address from where my java program is connecting to <myHost>. Do you still think I should use ftp.getAdvancedFTPSettings().setActiveIPAddress("10.172.154.82") ?

Ok, that won't help then. I thought it might have been a local address.

Try using Windows ftp.exe to see if that works. Otherwise you might have to switch to passive mode - I can't see anything wrong with the PORT command you sent.

from my windows development box. Everything works fine. ftp.exe and the java program are successful.

But from a linux box(Amazon Linux AMI release 2011.02.1.1) the java program does not work but if I use the ftp program it works fine.

Post the debug output from the ftp program on Linux. There must be something different about the PORT command used.
