Hi,

It takes a very long time for NTP on my system to find my oncore as system
peer. Thanks for any insight. -- Mario


 Here is my configuration file /etc/ntp.oncore.0

*************************************
MODE 2
#LAT   42 23.556
#LONG  -72 32.02620
#HT 70.0 m
DELAY 25.0 ns

ASSERT
HARDPPS

TRAIM YES
SHMEM /var/log/ntpstats/ONCORE.0

and my log file /var/log/ntpstats/clockstats:
