curl/tests/server/getpart.c
Daniel Stenberg 14424f7058 Modified the FTP server to use the new 'sockfilt' program to do all the socket
level stuff. The FTP server communicates with sockfilt using perl's open2().
This enables easier IPv6 support and hopefully FTP-SSL support in the future.
Added four test cases for FTP-ipv6.
