port command successful consider using pasv

找了半天。必须记录一下！

1. Windows ftp client doesn’t support PASV mode yet,so if you want to use PASV mode, you may need to change your ftp client, for example: filezilla
2. Ftp active mode means ftp server will connect to ftp client when client get file from server

So if you have this problem and you don’t want to change your windows ftp client, please try to
stop your windows firewall and then try ftp again, if it works, add a rule forwindows/system32/ftp.exe in your firewall allow process list
