These utilities can be used on Niagara hosts that run the Windows OS, but they are
not supported on JACE-4/5s.
Using Windows Command-line Utilities
The versions of these utilities that ship by default with the Windows OS are executed
at a command prompt. However, there are many GUI versions freely available for
download from the Internet. Examples provided in each subtopic were run at a
command prompt of a Windows 2000 host.
Opening a

As is true for most programs that execute from a Windows command line, you can
receive information about additional program options by typing:
<ProgramName> /?
where <ProgramName> is the name of each utility described in the next section.
TCP/IP Utilities
ping Packet Internet groper (ping) is a utility that checks the availability and response time
of a network host. It uses the Internet control message protocol (ICMP).
The
ping utility is typically used to determine whether one host can reach another
host. For example, if Host A (Pluto) was having difficulty connecting to Host B
(Saturn), an administrator could
ping the IP address (or name) of Saturn to see if it
responds. If the host does not respond, there could be a problem with the host
configuration, or the Ethernet connectivity (cable, Ethernet card, hub). If the host
responds, but responds slowly, that may indicate other problems more easily
diagnosed with the
tracert utility (see the next section).
