There is no direct way to open a filehandle on a remote server; you would need to open a socket to the remote server, with a process at the other end of the socket cooperating in writing the file. (For example, HTTP works by having your browser open a socket to the remote machine and sending a request; then the web server on the remote machine cooperates by sending back the requested data.)

The easiest solution in this case is probably to create the configuration file locally, and then upload it to the remote server with Net::FTP.
