To disable:
Just comment out lines in /etc/inetd.conf. Then restart inetd for the changes to take effect.

Code:

netstat -a

netstat lets you search for open ports which do not use inetd. Then turn off those proccesses individually.

To enable - uncomment inetd.conf

I do not know anything about unkown ports. You cannot block something you do know about ahead of time...? Or do you mean prevent some specific port number from ever being used?

If it is not a service, then you have to use a firewall to block/allow a specific port, not inetd.conf.
You can really mess things up by turning off required services or blocking required ports. Example: port 22
see here for IANA ports:
