Hi, I am using Fedora 3.1.0-7.fc16.i686.PAE . I am developing an application that tunnels FTP packets from Ftp client to the FTP server via TUN device. My application demands relation between FTP control and data connection. I have seen /proc/net/nf_conntrack file..But it only lists the connections and doesnot provide the info of relation between them. Any help or pointers would be appreciated. Regards,
