Id very much like to do this but it doesn't seem to be enabled on my installation.
# rpm -qa | grep pdns pdns-4.1.5-1pdns.el7.x86_64 pdns-recursor-4.1.7-1pdns.el7.x86_64
Ive tried both iterations in pdns.conf (enable-lua-record and global-lua-record) to the same effect:
pdns_server: Fatal error: Trying to set unknown parameter 'enable-lua-record'
It this to be slated for v4.2? Seems to be some mixed signals out there as to whether or not it's currently available.
Also - v4.2 doesn't seem to have a release schedule. The last info I found was from 10/2017 referring to a beta. Is the current 'master' build of reasonable stability? The ultimate goal is to enable round-robin DNS and this (via LUA) seems to be the only avenue.
EDIT: some possibility here. I wish they had included the actual records they used.
