Yes, the DNS resolution in ntpd is really, really stupid. I always specify addresses in ntp.conf for this reason and the fact that it there are multiple addresses only the first returned will be tried. It never fails over if that one is dead. (And, should an IPv6 address be available on a system that does not have IPv6 connectivity...). -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
