If you found this message when you are accessing vsftpd ftp server, then you need to do this:

[root@Production]/etc/vsftpd# ftp localhost
Connected to localhost (127.0.0.1).
220 (vsFTPd 2.2.2)

ftp> debug
Debugging on (debug=1).
ftp> ls

550 Permission denied.
Passive mode refused.

So actually the cause of this is that PASV mode is turned off (which actually I turned it off purposely).
