Thanks to all who responded. I definitely got the information that I
needed. Here's the summary:

The file "/etc/services" is a dictionary or sorts which is used only to
provide a mapping between ports and service names so that programs can
reference the service by a name instead of a number. The "/etc/services"
usually comes with traditional port numbers and names defined already
but you can change the port number for a service name if you don't want
to use the old standard one.

If you want to disable some services, you must comment corresponding
lines in /etc/inetd.conf

Or, for standalone services, you must disable daemon starting.
The starting scripts are generally in /sbin/rc3.d/S*.


And ... rdg is the reliable datagram facility, apparently included with
TruCluster.


Here's my original post:

I would like to disable unused tcp ports. I 've already removed all
those in /etc/services that i don't need, but when I do a netstat i
still see some ports not in /etc/services that are LISTENING. These are
ports that were never in /etc/services to begin with.

One other quick question about ports... could some tell me what the
service "rdg" is used for?
