Inetd Replacements
In recent years, because of the security limitations in the original design of inetd, it has been replaced by xinetd, rlinetd, ucspi-tcp, and others in many systems. Distributions of Linux especially have many options and Mac OS X (beginning with Mac OS X v10.2) uses xinetd. As of version Mac OS X v10.4, Apple has merged the functionality of inetd into launchd.
The services provided by inetd can be omitted entirely. This is becoming more common where machines are dedicated to a single function. For example, an HTTP server could be configured to just run httpd and have no other ports open. A dedicated firewall could have no services started.
systemd supports inetd services, and expands socket activation beyond IP messaging (AF_INET+6) to include AF_UNIX, AF_NETLINK and more.

Famous quotes containing the word replacements:
“The replacements are all like that. Not even old enough to carry a pack. All they know how to do is die.”
—Maxwell Anderson (1888–1959)
