xinetd is a replacement for inetd, the internet
services daemon. Anybody can use it to start
servers that don't require privileged ports
because xinetd does not require that the services
in its configuration file be listed in
/etc/services. It can do access control on all
services based on the address of the remote host,
time of access, connection attempts, or process
limits. Access control works on all services,
whether multi-threaded or single-threaded and for
both the TCP and UDP protocols. xinetd supports
both internal access control, and the use of the
libwrap library. IPv6 with access control is also
supported. It can redirect service requests to
other machines, and has the standard built in
services, including tcpmux.
