Hello again (and sorry for the flood of posts),
in order to unconfuse myself I have done a new and easier setup of my
problem.
Now I have only got one server and one client.
The servers configuration is:
restrict default notrap nomodify nopeer noquery
restrict 127.0.0.1
driftfile /var/status/ntp.drift
pidfile /var/run/ntpd.pid
server 127.127.1.1
fudge 127.127.1.1 stratum 7
The clients configuration is:
restrict default notrap nomodify nopeer noquery
restrict 127.0.0.1
driftfile /var/status/ntp.drift
pidfile /var/run/ntpd.pid
server 10.9.94.165 iburst
server 127.127.1.1
fudge 127.127.1.1 stratum 13
To run into the problem that the client is not syncing to the server I
--> stopped the NTP service on both client and server
--> changed the time on the client back to january of 1975
--> started the NTP service on the client
--> started the NTP service on the server a little later
Hope that clarifies the situation...
