Thank you Dr. Mills for your reply and suggestion to use the latest
p127 dev version. I'm wondering if this dev version is stable enough
to use it in a commercial product.

As Harlan (thanks) correctly pointed out the reason ntp-keygen didn't
work in my 4.2.4p5 build was that I didn't build it with crypto and
openssl options. I rebuilt it with those options and ntp-keygen works
as I expected.

Thanks again.

Joe
