ntp.conf on the server:
server 127.127.1.0 burst iburst minpoll 4 maxpoll 4
fudge 127.127.1.0 stratum 10
trap 127.0.0.1
restrict default noquery nomodify
restrict 127.0.0.1
driftfile /var/lib/ntp/drift/ntp.drift
logfile /var/log/ntp
disable kernel
and on the client:
server 127.127.1.0 burst iburst minpoll 4 maxpoll 4
fudge 127.127.1.0 stratum 12
server 192.168.1.4
restrict default noquery nomodify
restrict 127.0.0.1
driftfile /var/lib/ntp/drift/ntp.drift
logfile /var/log/ntp
disable kernel
And standard options I think:
/usr/sbin/ntpd -p /var/run/ntp/ntpd.pid -g -u ntp
The thing is that the ntptime problems are intermittent. Sometimes
ntptime returns ERROR and other times OK. I can't see any pattern to
it.

Actually the client may serve as a server in case its upstream
reference disappears. So that other pure clients can still get time
from someplace.
