You know in rereading this initial portion of the original message, I
was struck by the fact that no mention of ntp.conf was made. Isn't step
tickers just used by the redhat init scripts at startup? I always add
something like
server my.time.server.name
to /etc/ntp.conf
Seems like there is an issue with the broadcast client being enabled too
so I think I have had to comment it out.
here is the ntp.conf on my local time server that all the other local
machines look to.
[bhughes@bretsony bhughes]$ ssh gateway1 'cat /etc/ntp.conf'
#
# Undisciplined Local Clock. This is a fake driver intended for backup
# and when no outside source of synchronized time is available. The
# default stratum is usually 3, but in this case we elect to use stratum
# 0. Since the server line does not have the prefer keyword, this driver
# is never used for synchronization, unless no other other
# synchronization source is available. In case the local host is
# controlled by some external source, such as an external oscillator or
# another protocol, the prefer keyword would cause the local host to
# disregard all other synchronization sources, unless the kernel
# modifications are in use and declare an unsynchronized condition.
