UNIX for Beginners Questions & Answers

Welcome,

I will probably install on all four of my Macs.... it's pretty cool !!

Slowly converging (as it should), after initial install a few minutes ago:

and the time on my mac pro has converged.....

Update:

Chrony now running on three of my Linux Ubuntu servers and all four of my Macs ( 2 MBA, I MacMini and 1 MacPro).

So, for the most part I have retired ntpd in favor of chronyd.

All boxes show system times within a few microseconds of NTP time.

I want to take this time to thank gull04 for suggesting Chrony in this earlier post, in this discussion:

So it may well be that I'll have to change to Chrony

I've mostly made the switch thanks to Gull04! Thanks for the idea.

One more concern, kindly reply on this, if we're doing update or upgrade using yum for ntp and ntpdate packages we can update upto ntp-4.2.6p5-29.el7.centos.x86_64.rpm version only, also link it's showing for centos 7 ntp-4.2.6p5-29.el7.centos.x86_64.rpm is the lastest version, We couldn't update ntpd 4.2.8p13@1.3847 which you shared the version.

Also tried downloading ntp-4.2.8p13.tar.gz version from your link and followed INSTALL file, it's not working.

Can you confirm for Centos 7 which i updated is the correct latest version?

Please reply on this

I already mentioned that the Cento, Ubuntu, etc. Linux distribution versions are outdated and to get the latest version you need to install manually and I provided the link to the downloads, the instructions and the vulnerability page.

I think I was very clear on this.

If you want a more secure version, you need to manually install per the instruction on the ntp site I provided.

Please read my posts more carefully.

Thanks!

...and please, please do not let your security depend on what is available using yum or apt. These are tools to make updates easier but if the distribution has not updated, then you need to manually upgrade, as I have did (before I decided to switch over to Chrony because I find the ntp history of vulnerabilities not acceptable, but that is just me. YMMV)

Yes, at current that's the latest for Centos 7.

The -29 is the RedHat fix level. They did 29 fixes on the ntp-4.2.6p5 from ntp.org.
You can get some details from

Code:

rpm -q --changelog ntp

Please note, version:

ntp-4.2.6p5-29.el7.centos.x86_64.rpm

... is eleven years old.. and is not current and resides in the ntp historical archives.
