HiPing

HiPing is useful in testing and debugging TCP/IP troubles. It
transmits an ICMP echo datagram to a remote system. If the
remote returns the message, the connection is considered valid.
If the remote system does not echo the message, it only means
that the remote system did not respond. That is, a lack of a
response can be caused by a number of different reasons (you are
not connected to the network, the remote may not be connected,
the remote may not support echo requests, or it may just be too
busy to reply). HiPing supports command line parameters and HTML
file format reports.
