"xinetd - extended Internet services daemon - provides a good security against intrusion and reduces the risks of Deny of Services (DoS) attacks. Like the well known couple (inetd+tcpd), it allows to fix the access rights for a given machine, but it can do much more. In this article we will discover its many features."

"The classical inetd helps to control network connections to a computer. When a request comes to a port managed by inetd, then inetd forwards it to a program called tcpd. Tcpd decides according to the rules contained in the hosts.{allow, deny} files whether or not the request is allowed. If the request is allowed the the corresponding server process can be started (e.g ftp). This mechanism is also referred to as tcp_wrapper."

"xinetd provides access control capabilities similar to the ones provided by tcp_wrapper."
