This doesn't happen on alpha. Probably an endian thing, but
the (4.2) code looks OK at a first glance. (NTOHL_FP uses ntohl
You could try to query the sparc64 from an LE box and vice-versa,
and you could uncomment the WORDS_BIGENDIAN in
src/usr.sbin/ntp/include/config.h und see whether it makes a
I wouldn't put much effort into the in-tree ntp however. Better
try 4.2 to shake the bugs out.
