- super server
- A super server (sometimes also called "super daemon") is a daemon (=
UNIX server process) that waits for connections on the ports of various
server programs and starts the corresponding server when a connection is
made. This way, there is only one server process for a set of services
(instead of one for each service), but each service in the set is
available to its clients.
The most common super servers are
inetd (the "InterNET Daemon"
that comes with many UNIX installations) and
xinetd (the "eXtended InterNET Daemon").
- A Tcl/Tk based interface to gnats.
