Proviamo: # nast -c
nast: invalid option -- c
Usage:  nast
        -h (This help)
        -i (Interface - default eth0)
        -p (Set promisc mode)
        -d (Print ascii data)
        -x (Print ascii-hex data)
        -l <File name> (log data/scanning report into a file)
        -f <"filter"> (apply filter)
        -P <ip> (Check for promisc node in the LAN)
        -m (Build hosts list of the LAN)
        -s (Follow TCP Stream)
        -g (Try to find a valid gateway)
        -r (Reset a connection (use with caution))
        -S (Port Scanner -SYN style-)
        -M (Port Scanner all LAN's host -SYN style-)
        -L (Try to resolve if there's a HUB or a Switch in the LAN)
        -b (Catch daemon banner for the hosts in the LAN)

        -G (Run ncurses MENU - This option is available only if you have
compiled nast with ncurses support, this is the default if I found
libncurses installed in your *unix-box)

Non mi sembra che ci sia un opzione -c. Forse che la confondi con un
altro tool? Ciao.
