Systems are unable to use IPv6 during file transfer through FTP
I have configured two machines through ipsec-tools and fedora linux kernel 188.8.131.52 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
"500 OOPS: vsf_sysutil_bind" error occured after FTP connection
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
