Sorry for jumping in so late.
In my opinion the basic concept of the local clock driver was good, easy to
configure, sufficient for small, simple networks, and it just worked as
expected in older versions of ntpd.
As David Woolley has pointed out in one of his comments, the local clock can

Hi All,
Please find my scenario:
I have one machinewhich will have multiple blades[nodes] as below:

Let say A,B,C,D,E are nodes in one machine..
I have configuration such a way that A will contact to the external server
for time synchronization and B,C,D,E will contact to

Hi,
And we keep telling you to get rid of the local server. And you keep
ignoring the advice and plowing on
If I get rid of local server for me it is working fine.
If i remove the local server it is working fine.
Thanks all for the help.

Bhargav,
Lose the local refclock.
Use orphan mode instead.
Orphan mode is documented in the Support web at support.ntp.org.

Hi,
Thanks for reply.
I am confused with what is a leaf node and non-leaf node.
It sounds to me that you have effectively removed the local clock
entirely. The local clock needs to be treated as a refclock, so that time
served remains valid indefinitely. On modern ntpd's, even without orphan

A leaf node is a system running ntpd that does not serve time to any
other system. As the main effect of the local clock is to declare the
time valid when it would not be valid by the normal rules, it is only

A leaf sits at the end of a branch. I presume it is a node on which
nothing else depends. Ie, no other machine uses it as a server.
It sounds to me that
My machine is the server for other nodes[blades] in the cluster.So it is
not a leaf machine.
The main issue is that, if local clock is there there is an issue with the
flag check in the peer_unfit ()..If the flag check is not there then even
if local configuration is there everything is fine.

Hi,
Can anyone explain me this part of code in ntp_proto.c:

* A distance error for a remote peer occurs if the root
* distance is greater than or equal to the distance threshold

Hi,
Thanks for the reply.
I have one query regarding this:
in the function refclock_newpeer() in the file ntp_refclock.c we are
setting the flag for each peer in the hash table as
peer-flags |= FLAG_REFCLOCK;
So, when the NTP packet is received we will iterate through all the hash
trees and
