ntp - pool.ntp.org

Post by elljay » 2019/09/14 07:43:43

Hi, I'm one of the volunteer admins at pool.ntp.org - I'm not a Centos user so apologies if I'm posting this in the wrong place!

In v4.2.6 of ntpd there was a new "pool" command introduced which for hosts getting time from the NTP pool allows them to automatically request a new server from the pool if one of the current servers they are using becomes inaccessible. I had a look at what I think is the current Centos ntpd package (https://centos.pkgs.org/7/centos-x86_64 ... 4.rpm.html) and it looks like the default config is using "server" rather than "pool".

So my question is, how do I go about requesting the default ntp.conf file to change from the current:

Code: Select all

server 0.VENDORZONE.pool.ntp.org iburst
server 1.VENDORZONE.pool.ntp.org iburst
server 2.VENDORZONE.pool.ntp.org iburst
server 3.VENDORZONE.pool.ntp.org iburst
to:

Code: Select all

pool 0.VENDORZONE.pool.ntp.org iburst
pool 1.VENDORZONE.pool.ntp.org iburst
pool 2.VENDORZONE.pool.ntp.org iburst
pool 3.VENDORZONE.pool.ntp.org iburst
Thanks. :)

As you may be aware, CentOS is a rebuild of RHEL sources and the upstream ntp has that "server" in the default ntp.conf, pointing to x.rhel.pool.ntp.org. CentOS only changes the "rhel" to "centos".

I think it would be beneficial if you could file a bug about this via bugzilla.redhat.com, product Red Hat Enterprise Linux 7, component ntp. If RH changes the "server" to "pool" in their default config, the change would propagate to the CentOS ntp package as well.

Thanks for the quick reply. 8-) I will submit a bug report to Redhat.

I'd also say raise a bug on bugs.centos.org too as the ntp package, and specifically the config file, is already modified by CentOS to change those very lines to point to 0.centos.pool.ntp.org etc and not the redhat equivalents.

CentOS 6 goes EOL sooner rather than later, get upgrading!

I checked chrony and it still uses 'server' instead of pool.
