[chrony-users] issues syncing between chrony and ntp

["Bauer, Steven J." <Steve.Bauer@xxxxxxxxx>]

Software versions:

Chrony version 1.25

Ntp: 4.2.6p3

 

Currently, The host running chrony is a stratum 1 server using a locally attached gps (gpsid) reflock using the SOCK interface.

 

The host running ntp  with a configuration like:

server ntp.sdsmt.edu

server 0.gentoo.pool.ntp.org

server 1.gentoo.pool.ntp.org

server 2.gentoo.pool.ntp.org

server 3.gentoo.pool.ntp.org

 

What happens is that it appears the queries for time to the host running chrony never work.

 

If I do a ntpq –p on the machine running ntp I get:

 

silver ~ # ntpq -p

     remote           refid      st t when poll reach   delay   offset  jitter

==============================================================================

ntp.sdsmt.edu   .INIT.          16 u    -   64    0    0.000    0.000   0.000

ip-173-201-38-8 198.153.152.52   2 u   18   64    3   66.030    2.070   0.089

mail.scottishtr 139.78.135.14    2 u   17   64    3   47.528   -7.556   0.129

name1.glorb.com 128.252.19.1     2 u   13   64    3   33.976   -0.975   0.243

smtp.envirahost 128.138.188.172  2 u   14   64    3   47.641    1..468   0.119

 

 

Now, the workaround that I found to get it to work was to add a version 3 on the server line in the ntp.conf as well as specify the ipv4 address of the host running chrony on the host running ntp.

 

Granted this work around works, but is there something that needs to be done on chrony/chrony.conf so that ntp can automatically figure out the ntp version rather than having to modify all of the hosts that we have running ntp on them?

 

Granted if I replace ntp on the second host with chrony the stuff works great as well.

 

Thanks for your help!
