One potential source of Permission Denied on a network socket for the root
user is the ipfw system. Do you have IP firewalling enabled, using either
ipfw or ipfilter, and if so, could those rules potentially be denying the
packets being generated? If you have logging/counters available for those
rules, do they go up when you run nmap?
