Hi, Kernel.org already disabled FTP years ago [1]: "... we're thinking it's time to terminate another service that has important protocol and security implications -- our FTP servers." So netfilter.org will also be shutting down FTP services by June 12th 2020. As an alternative, you can still reach the entire netfilter.org software repository through HTTP at this new location: https://netfilter.org/pub/ Thanks. Pablo, on behalf of the Netfilter coreteam.
