Note, that you must run this as root per the man page for the -i wait option: Youve forgotten about one little thing: arp keeps mac<>ip association of recently contacted peers, so its quite often not to find the mac<>ip association were looking for, of machine that exists in the network.When we add in a fractional wait time of say, a half second, we should now get 12 packets sent within the 6 seconds: $ sudo ping -i. So, using the default of sending 1 packet every 1 second, the options -t and -c will produce the same output. The default is to wait for one second between each packet. Wait seconds between sending each packet. Looking at the man page for ping ( man ping) under the -i wait option, we see that the default time between sending pings is 1 second:
