Aren't port numbers 0-1023 privileged under Unix and therefore only to applications running as root? If you're running your application as a regular user, it can't open a listening socket on port 123. It should still be perfectly able to send requests to port 123 on other 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.
