The first thing to look at is if you're talking ftp or sftp.  Those two
are quite different, run on different ports, and have very different
security requirements.  SFTP is simply an SSH server that accepts
ftp-like syntax and runs on port 22.  Traffic is encrypted the whole
way.  FTP runs on ports 20 and 21 and has a nasty habit of dynamically
assigning ports for passive connections.

Secondly, you need to decide who's the client and who's the server.  You
don't have an sftp server talking to an ftp server.  Somebody is
initiating the connections, whether it's ftp or sftp.
