Bruno Georges commented on JBESB-303:
-------------------------------------

This problem seems to happen with some FTP servers and not others.

Example of Cerberus FTP Server running on Windows:

Jan 05 10:35:33  38  Incoming connection request on interface 1.10.102.115
Jan 05 10:35:33  38  Connection request accepted from 1.10.102.115
Jan 05 10:35:33  38  USER test
Jan 05 10:35:33  38  331 User test, password please  
Jan 05 10:35:33  38  PASS ***********
Jan 05 10:35:33  38  230 Password Ok, User logged in  
Jan 05 10:35:33  38  TYPE I
Jan 05 10:35:33  38  200 Type Binary  
Jan 05 10:35:33  38  CWD /ftproot/tmp/EsbInput
Jan 05 10:35:33  38  250 Change directory ok  
Jan 05 10:35:33  38  PORT 1,10,102,115,5,72
Jan 05 10:35:33  38  200 Port command received  
Jan 05 10:35:33  38  NLST *.dat
Jan 05 10:35:33  38  150 Opening data connection  
Jan 05 10:35:33  38  550 NLST command failed  
Jan 05 10:35:33  38  QUIT

The same commands on Linux VSFTPD do not return any errors.
