NcFTPd general.cf file configuration
Don't forget to restart NcFTPd after modifying the general.cf file.
Using this option you can configure how many remote FTP clients per the same IP address are allowed simultaneously. This can be useful to set if you find that users are opening up dozens of connections and monopolozing the server for themselves.
Note that some clients always try opening two or more connections and may cease to work if they can't do that.
