Aren't port numbers 0-1023 privileged under Unix and therefore only

hosts and receive answers to those requests.
That is exactly what I am trying to do (and which worked perfectly on
Tiger): send some message on port 123 (to some ntp server) and receive
an answer.
On Leopard I send, but never get an answer.
It does not seem to be an endian issue (the running version was last
tested on a Tiger iBook ppc) - both intel and ppc produce the same 48
byte packages.
I really don't know what to try next.
Kind regards,
Gerriet.
