Summary: ntp question

Thanks to Andrey Borzenkov for replying to this.

Here is his reply;
=====
Basically, falsetickers are servers that are less "trustworthy" than others.
Out of 2n+1 servers normally n servers are considered as "falseticker"
compared with remaining n+1, which are "truechimers".

In your case it is probably due to large dispersion which makes it less
predictable than others.

Morning all,

hopefully this isn't too off topic but I haven't found the answer to this on
the internet or in the documentation.

I've configured ntp on a pair of boxes so they both point to 2 GPS ntp
servers and are also peers of each other for redundancy. It all seems to
work OK, but occasionally one of the peers is marked as 'falsticker' in ntpq
-p output. eg;

server1 $ ntpq -p
     remote           refid      st t when poll reach   delay   offset
disp
==============================================================================
 LOCAL(0)        LOCAL(0)         8 l   34   64  377     0.00    0.000
10.01
+ntp02           .GPS.            1 u   17   64  377     2.52   60.328
0.37
*ntp01           .GPS.            1 u    6   64  377     0.44   -2.549
1.07
xserver2         ntp01            2 u  138 1024  356     7.03   -0.986
16.68

After a while the server2 line will go back to having a '+' in front of it,
ie it is included in the final selection set.

Can anyone explain what falsticker means please?

Thanks,

Richard
