Hi Darren,
That is where I get doubts I see only one lease from that 4.0.0.0 subnet
when I execute this command
/usr/bin/echo '{"command":"lease4-get-all"}' | /usr/bin/socat -
UNIX:/tmp/kea4-ctrl-socket and that is also the day before yesterday's one
where it worked fine.
And we have around 150+ Ip's still available from that subnetThanks Kraishak On Thu, Jul 20, 2023 at 11:47 PM Darren Ankney <darren.ank...@gmail.com> wrote: > Hi Kraishak, > > I found an example transaction (0x67937012) showing a failure (logs > below).
