It shouldn't really matter what host type the client or the server is.

There are probably scripts out there that will do this or something similar (or you could use a command line tool like ncftp or plain old ftp).
If you've got five minutes, read the perldoc for Net::FTP, and you should be able to knock together a script yourself.

If that doesn't appeal, have a rummage through the Code Catacombs, particularly FTP stuff.
