xinetd

Synopsis

                  xinetd [options]

TCP/IP command. The extended Internet services daemon. (On some systems this replaces inetd.) Similar to inetd, xinetd saves system resources by listening to multiple sockets on the behalf of other server programs, invoking necessary programs as requests are made for their services. Beyond this, xinetd provides better logging facilities, including remote user ID, access times, and server-specific information. It also provides access control facilities. Not limited to system administration use, it can launch services that are not listed in /etc/services. Unprivileged users can use this tool to start their own servers.
