How do I tickle NcFTPd so it reloads its configuration files?
Currently NcFTPd cannot reload the general.cf, so if you modify it, you need to do a full restart. But you can have it reload the domain.cf, and to do that, you send the main NcFTPd process a hangup signal (SIGHUP) using kill HUP (or kill 1). See the section on how to shutdown NcFTPd for how you can find out which process is the main process.
