ping
The traceroute command first sends probe datagrams with the TTL
u
value set at one. This causes the first router to discard the datagram
and return an error message. The trace function then sends several
probe messages at each subsequent TTL level and displays the round-
trip time for each message. Not all devices respond correctly to probes
by returning an "ICMP port unreachable" message. If the timer goes off
before a response is returned, the trace function prints a series of
asterisks and the "Request Timed Out" message. A long sequence of
these messages, terminating only when the maximum timeout has
been reached, may indicate this problem with the target device.

count - Number of packets to send. (Range: 1-16)
size - Number of bytes in a packet. (Range: 32-512)
The actual packet size will be eight bytes larger than the size
specified because the router adds header information.
