[Techtalk] closing ports in /etc/services

Hi carla,
I don't want to all RTFM'y on you, but 'man servises' is a good resource
for this...
<snip>
services is a plain ASCII file providing a mapping between friendly
textual names for internet services, and their under-
       lying assigned port numbers and protocol types. Every networking
program should look into this file to get the port  num-
       ber  (and  protocol)  for its service.  The C library routines
getservent(3), getservbyname(3), getservbyport(3), setser-
       vent(3), and endservent(3) support querying this file from programs.

hope this provide's insight.
stratis. :)
