|
<dt><i>Option</i> can be one of the following:</dt>
|
|
</dl>
|
|
|
|
<ul>
|
|
<li>-service</li>
|
|
<li>-address</li>
|
|
</ul>
|
|
|
|
<p>The -service option takes one argument: a service name or port
|
|
number. Enter a service name (i.e. "http" or
|
|
"telnet") and dp_netinfo will return the active server
|
|
port for that service based on the system configuration. In
|
|
UNIX, this information is usually stored in /etc/services.
|
|
Likewise, you can give it a port number and it will return the
|
|
name of the service on that port.</p>
|
|
|
|
<p>The -address options allows one to translate from IP address
|
|
to hostname and vice versa. It also takes one
|
|
argument: an IP address (127.0.0.1) or a hostname
|
|
(www.foobar.com) and returns the cooresponding value.</p>
