Hello,

I used the following command: ncrack <ip> -p ftp --user admin --pass "" -m ftp:cr=1. The ftp service on the ip I used is giving the following when I try to connect to it manually : "421 Service not available, remote server has closed connection." I need from ncrack to terminate after one try for ips with the same issue or when the ftp port is closed. Whereas, ncrack keeps retrying infinitly to establish the connecction!!
