  NAME

    ping - Sends ICMP ECHO_REQUEST packets to network hosts

  SYNOPSIS

    ping [-R][-v] host [packetsize [count]]

  FLAGS

    -R  Provides information on the Internet routers that the ICMP echo packet
        is being sent through.  When this flag is used, an option field of the
        IP header is defined to accept record route data as it passes through
        each router.  The option header is large enought to accomodate nine
        router addresses.  If the number of routers in the path is greater
        than the size of the option header, the option header is flagged as
        invalid.  The -v flag must be used with the -R flag to see the results
        of the record route option.

    -v  Provides verbose output.  Lists any ICMP packets, other than
        ECHO_RESPONSE, that are received.

  DESCRIPTION

    The ping command measures the round-trip delays and packet losses across
    network paths.  It uses the ICMP protocol's mandatory ECHO_REQUEST
    datagram to receive an ICMP ECHO_RESPONSE from the specified host, or
    network gateway.  ECHO_REQUEST datagrams, or ``pings,'' have an IP and
    ICMP header, followed by a struct timeval, followed by an arbitrary number
    of bytes to pad out the packet.

    If there is no response from the specified host, then no output is
    displayed.  The ping command computes round trip times and packet loss
    statistics and displays a summary of this information when the command is
    terminated.  The command can be terminated with an interrupt signal
    <Ctrl-C>.

    The default datagram packet size is 64 bytes, or you can specify a size
    with the packetsize command-line parameter.  If an optional count is
    given, ping sends only the specified number of requests.  The packetsize
    parameter must be included if a count is specified.

  EXAMPLES

    The following example illustrates the use of the record route option (the
    -R flag).  You will see the results of the record route option only for
    the first packet received, unless the route changes for a subsequent
    packet, then information on the the new route will be displayed.
