[Kea-users] Sockets not creating when starting kea-ctrl-agent

[Peter Davies]

Hi Johathan,
    The kea-ctrl-agent listens for commands on http://192.168.20.254:8000 .

The kea-dhcp6 and kea-dhcp4 processes create and listen on the Unix sockets.
Have you configured kea-dhcp6 and kea-dhcp4 to listen on these sockets, 
and are
these processes running?

Kind Regards Peter
