|From (Unix) inetd|
All modern Unix systems handle a large number of the services they
run through the super-server inetd or one of its descendants (xinetd, systemd
etc.) Such a program reads a configuration file (for example
and opens server-sockets on all ports defined in this file. As a request
comes in it accepts it and starts the associated server such that
standard I/O is performed through the socket. This approach has several
The very small generic script for handling inetd based connections is
inetd_httpd, defining http_server/1:
Here is the example from
#!/usr/bin/pl -t main -q -f :- use_module(demo_body). :- use_module(inetd_httpd). main :- http_server(reply).
With the above file installed in
the following line in
/etc/inetd enables the server at port
4001 guarded by tcpwrappers. After modifying inetd, send the
HUP signal to make it reload its configuration.
For more information, please check inetd.conf(5).
