Systems are unable to use IPv6 during file transfer through FTP

Hi,

I have configured two machines through ipsec-tools and fedora linux kernel 2.6.18.2 to make them communicating by using IPv6 and IPsec.

For testing, I have tried to send packets through ping6 and FTP (vsftpd-1.1.3-8 ) and analysed the packets through ethereal.
.
When I use ping6, IPv6 is used for communication and packet is also encrypted as it is using ESP.

When I send a file through FTP, it uses IPv4 rather than IPv6.

Any suggestions or comments that why it is not using IPv6 during file transfer through FTP

Regards,

I am using FTP server VSFTPD (vsftpd-2.0.1-5.i386) and I have also configured it for IPv6.
The guideline that I have used is in the following link
http://www.ibm.com/developerworks/we...?ca-dgr-lnxw06
Section "Configuring the Linux FTP server vsftpd for IPv6"

It is also mentioned in the following link as well
http://antwort.42h.de/archives/11-Ip...th-vsftpd.html

The client and server machines are also IPv6 enabled as I am using Fedora linux Kernel 2.6.18.2. During upgrading the kernel version, I have enabled all IPv6 options in 'make xconfig' step

But the problem still exists.

Any suggestions

I think the FTP client itself is not IPv6 enabled ...so I have installed lukemftp-1.6-beta2 ftp client which is IPv6 enabled. After installation, I have used the following command to connect to ftp
..]# ftp6 fe80::250:bfff:fe38:26f3%eth0

It connects to the ftp server successfully but when I tried to list the file through ls command I got the following error
500 OOPS: vsf_sysutil_bind
500 OOPS: child died
421 Service not available, remote server has closed connection.

I am using vsftpd-2.0.1-5.i386 ftp server.

Amy suggestions why I am getting this error
