The LIST command requires a data connection to send back the output
and the data connection requires a PORT or PASV command so that both
sides know what IP/port to use.

Try it with telnet or netcat first to see how it works (you might want
to read the FTP RFC first) and then see if it makes sense to use
libcurl for what you want to do.
