altering ftp response code upon making a connection

I'm trying to configure (or rather break) a proftpd server (on linux - FC6) so that it gives a response code of anything other than a 220 when making a new connection. The script I'm developing does not login/authenticate as the requirement is that no login credentials can be provided. So I'm scratching my head trying to figure out how to make the test server (which happens to be proftpd running on my localhost) give anything other than a 220 when connecting. Any ideas? Thanks.

I found the answer. pure-ftpd has an MaxClientsPerIP config option which I set to the value of "1" and opened one ftp session to it. Now all subsequent sessions will fail with a 421.
