| <h3 class="section">16.11 The <code>inetd</code> Daemon</h3> |
| |
| <p>We've explained above how to write a server program that does its own |
| listening. Such a server must already be running in order for anyone |
| to connect to it. |
| |
| <p>Another way to provide a service on an Internet port is to let the daemon |
| program <code>inetd</code> do the listening. <code>inetd</code> is a program that |
| runs all the time and waits (using <code>select</code>) for messages on a |
| specified set of ports. When it receives a message, it accepts the |
| connection (if the socket style calls for connections) and then forks a |
| child process to run the corresponding server program. You specify the |
| ports and their programs in the file <samp><span class="file">/etc/inetd.conf</span></samp>. |
