This tool successively tries couples of login and passwords in order to find matching authentication credentials. Parameter --login defines the logins to try. To check several logins, parameter --login-file is the file containing logins (one per line). Parameter --password-file is the file containing passwords (1/line). Parameter --stopatfirst indicates to stop when first match is found. Parameter --numthread defines the number of threads (simultaneous running checks) to use. Parameter --dst-ip is the address of remote host/server. Parameter --dst-port is the port number where to connect. Optional parameter --src-ip defines the local IP address to use. Optional parameter --src-port defines the local port number to use. Optional parameter --ip4opts permits to add IP4 options encoded as mixed. Optional parameter --ip6exts permits to add IP6 options encoded as mixed (first byte is the next header number). Optional parameters --device, --src-eth and --dst-eth permits to create a virtual client using fake addresses (in this case, tool have to be run with admin privilege in order to sniff and spoof at Ethernet level).
