The following is mostly taken from the gisdn documentation

INETD-Server-Installation

First you have to register a new service in your /etc/services.
"isdninfo" would be a great name. And 4711 would be a great port-number.
After that you should insert the following line in your /etc/inetd.conf: 

       isdninfo stream tcp nowait root /bin/cat /bin/cat /dev/isdninfo

Now give your inetd a HUP (killall -HUP inetd). Now the server should work.
Try a "telnet localhost 4711" to test the server-installation.
It should print out some rubbish. Cancel with ^].
The last thing you have to do, is to configure gimon for remote-monitoring.
This is done via the configuration-dialog. Activate
"Server mode" and enter the server name and port.
