Hello Hart,
I found that my ntp version is 3-5.93e which is before 4.2.6
So I should use the method 6.14.2. NTP Versions before 4.2.6 right?
If I am right, then from the description, I think I need to copy this leap second file to crypto directory. So could you tell me where is the crypto directory?
Thanks in advance.
The leap second file must be copied to the crypto directory configured for ntpd, and inside that directory a link must be created which points to that file. The standard name for the link is ntpkey_leap. However, this can be overridden by a configuration parameter.
