How to enable vsftpd( ftp server) for IPV6 and IPv4

1) yum install vsftpd

2) vim /etc/vsftpd/vsftpd.conf
     change :
         listen=NO
         listen_ipv6= YES
    
     For anonymous upload/dwnload

        anon_mkdir_write_enable= YES
        anon_other_write_enable= YES
          anon_upload_enable= YES

3)  service vsftpd start
    
4) Default path for upload /download directory

       /var/ftp/

5) The Linux native client (ftp) does not support IPv6, so use "lftp" to test the server.

6) Windows 7/ Windows 2008 Server ftp client will work so you can use "ftp ipv4/ipv6" command.
