Re: [chrony-users] DHCP and Chrony

I don’t think it’s built-in in chrony itself.

CentOS 7 for exemple ships with a helper wrapper that is run as a poststart in the systemd chrony unit file. This helper script does exactly what you want as it checks dhcp leases and add ntp servers referenced there to the sources list (it levereges chronyc cli) it also adds those referenced in DNS SRV records of the zone (if available)

The script’s path is /usr/libexec/chrony-helper

Hi Everyone,

I'm running chrony 3.2 on Ubuntu 18.04.  I was expecting it to add the NTP server in the DHCP list to the list of sources, but that's not happening. 

Being new to chrony, I may be missing something, but I'm not finding a way to configure chrony to pull the address from the lease, like NTP would.  

Is chrony capable of pulling an NTP server address from a DHCP lease? 

Thanks in advance!!
