In all the world you might find 4 machines still plugged in that
support 'record' or 'page' structure.  The default is 'file', which is
what that command is trying to do.

Add these two methods to ftp_server.py::ftp_channel

    def cmd_stru (self, line):
        'obsolete - set file transfer structure'
        if line[1] in 'fF':
            # f == 'file'
            self.respond ('200 STRU F Ok')
        else:
            self.respond ('504 Unimplemented STRU type')

    def cmd_mode (self, line):
        'obsolete - set file transfer mode'
        if line[1] in 'sS':
            # f == 'file'
            self.respond ('200 MODE S Ok')
        else:
            self.respond ('502 Unimplemented MODE type')


And that should do the trick.
