DESCRIPTION
Ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit
an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams
(``pings'') have an IP and ICMP header, followed by a ``struct timeval''
and then an arbitrary number of ``pad'' bytes used to fill out the
packet. The options are as follows: Other options are:
-c count
Stop after sending (and receiving) count packets. After the pack-
ets are sent, ping will wait up to ten seconds for replies to
arrive, then exit.
