Whenever you make changes to inetd.conf you should restart the daemon to make the changes effective.
The easiest way is to type something like this…
pkill -HUP inetd
This will send a HangUP signal to inetd so it will restart again and load its config file. Take a look at syslog to make sure you haven’t broke anything.
kill -HUP inetd
should also be used
