Doing so will speed up ntpd's initial sync from ~5 minutes to ~20 seconds. iburst causes ntpd to send the first 8 packets to the remote time server at 2 second intervals, instead of the default minimum of 64 seconds, whenever that server becomes reachable. After the initial 8 packets ntpd reverts to the normal poll times. > restrict ntp1.cs.wisc.edu mask 255.255.255.255 nomodify notrap noquery > restrict ntp3.cs.wisc.edu mask 255.255.255.255 nomodify notrap noquery > restrict nss.nts.umn.edu mask 255.255.255.255 nomodify notrap noquery > restrict ntp1.chiccp.net mask 255.255.255.255 nomodify notrap noquery > restrict 192.168.1.0 mask 255.255.255.192 > restrict 192.168.1.64 mask 255.255.255.192 > restrict 127.0.0.1 You could greatly simply your restrictions as follows: restrict default nomodify notrap noquery restrict 127.0.0.1 If you need to allow authorized clients on one of your sub-nets to query ntpd add the following as appropriate: restrict aaa.bbb.ccc.ddd mask 255.255.255.eee notrap nomodify More information about ntpd access restrictions is available at http://support.ntp.org/Support/AccessRestrictions > My problem is this: at startup, other servers are able to poll my NTP > server.

Please let us see the output of ntpq -p from the server at the following intervals after ntpd start up: 1 minute, 5 minutes, 10 minutes, 20 minutes. -- Steve Kostecke <[EMAIL PROTECTED]> NTP Public Services Project - http://support.ntp.org/ _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
