Running INN on a port other than 119

[Jurgen de Wijs <j.de.wijs@nospam.com>]

I want to combine nntpcache and inn on one machine. The nntpcache
documentation suggests to run INN on port 120 instead of 119.

When I change the "port" setting in inn.conf to 120 i get an error
message stating that INN could not use a privileged port because it
has not enough permissions.

>From a search in google i found that when you specifiy port 433 or a
port above 1023 it works.

How can I specify what users are allowed what ports in my system?
