PING
The 'ping' command is available on both UNIX and Windows95 hosts. It
can be used to determine whether the target is "alive", ie. responding
to network requests. The command syntax is as follows:
ping <hostname>
For example,
ping umeteor
The exact response from this command depends on the type of host software you
are using. On UNIX systems it will usually respond with "umeteor is alive".
On Windows95, it responds with a series of messages that state how long the
target took to respond to the test messages.
