You mean "56 data bytes" is the ONLY answer and nothing like:
64 bytes from 192.168.xx: icmp_seq=0 ttl=64 time=2.232 ms
64 bytes from 192.168.xx: icmp_seq=1 ttl=64 time=2.208 ms
64 bytes from 192.168.xx: icmp_seq=2 ttl=64 time=2.575 ms
64 bytes from 192.168.xx: icmp_seq=3 ttl=64 time=2.174 ms
?
If you don't get those lines every second until you cancel (or 3 times
in windows), then there's NO ANSWER and most probably the wrong IP
address.
That's the problem!
