Hi Harlan,
Thanks for the information. I understand your points. I'm *only* trying
to be get leap second fixes at the moment as we don't have much time to
test the new ntpd feature across all our platforms.
Yes, I'm testing the kernels too.
Also, I'll definitely encourage our folks to be part of NTP Consortium.
Thanks,
Mohan.

Hi,
We are currently using ntpd version 4.2.4p4.
Please see http://support.ntp.org/bin/view/Dev/ReleaseTimeline and
understand your choice.
You are running software that was released in December of 2006, and was
EOL'd in December of 2009 with 4.2.6, which fixed between 630-1000
issues.
4.2.6 was EOL'd in December of 2014 by the release of 4.2.8, which fixed
over 1,100 issues.
As Leap second insertion is very close, we are trying to be safe from it.
here are few questions,
- Is 4.2.4p4 capable of receiving "Leap Second" information from NTP
servers??
Yes.
Below is our configuration.
"server time.nist.gov maxpoll 10 minpoll 6
disable monitor
restrict default noquery
restrict -6 default noquery"
- Is there any way that I can test whether the current version is providing
of "Leap Second"??
- Are there any configuration changes required??
Required, no.
Useful, almost certainly. For example, you could keep an updated
leapseconds file on your server and refer to that in your config file.
Have you tested your kernels to make sure they can handle a leap second?
What about how your client machines will behave during the leap second?
- If our version is not good for handling leap second,
1. What will be closest version to upgrade from 4.2.4p4.?? or
Why would you *not* want to run the latest release of NTP?
2. Any patches that we can apply to make 4.2.4p4 safe.??
Perhaps, but you'd have to:
- look at somewhere between 1,700 and 2,100 patches
- decide which ones you wanted
- apply and test the patches
I'd also recommend your company (and EVERYBODY else who cares about
network time) join the NTP Consortium at Network Time Foundation now:
http://nwtime.org/membership/why-join/
The bind-9 tarball is about 8MB. The ntp tarball is about 6.5MB.
We don't have even 5% of the resources to develop and maintain NTP that
ISC has to develop and maintain BIND.
