Description:
The DARPA Internet is a large and complex aggregation of network
hardware, connected together by gateways. Tracking a single-point
hardware or software failure can often be difficult. 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.
