Help with ippool-dhcp servers (two in redundancy)

Hello Alan and Thompson,


I would like just one of the servers to reply and if it's offline the other


I am running:

*radiusd: FreeRADIUS Version 3.0.12, for host x86_64-unknown-linux-gnu,
built on Feb  2 2017 at 15:00:22*
*FreeRADIUS Version 3.0.12*

I don't think I have the up-to-date queries. I would love to run it over
PostgreSQL and I know that it is better but I don't have a reliable HA
environment for PostgreSQL. I downloaded version 3.0.15 and the queries
look exactly the same. I think until version 4 I will leave one of the
servers in standby and watching for the other server and, if the first get
down the script will enable the second one. Hot standby.
