[PEN-TEST] ports

["Dale, C" <cdale () SILLY TECHMONKEYS NET>]

I'm wondering if anyone knows of any URLs which list everything that would
be on certain ports.  I know of a large /etc/services file on the web at
this URL:
http://people.redhat.com/alikins/services.txt
but it is not complete.  Specifically, I am trying to find out what runs
on ports 6010 and 6011 on linux boxes.
Thanks,
Cindy
