ntpd with PPS on NetBSD/i386
Hi
I've had two pool servers as from late 2009 which until recently
were running NetBSD-5. I've attempted updates to NetBSD-6 and
find I can't get PPS support working.
I'm not sure if it's the PPS support in the kernel or the supplied
ntpd with NetBSD-6.
I've attempted to compile on NetBSD-6 from the ntpd sources that I
downloaded from ntp.org and the binaries from that compile don't
work correctly. Compiles from NetBSD-5 complete and install/work ok
on NetBSD-5.
Any help appreciated.
David
