[Kea-users] Problems setting up HA

[perl-list]

Are you running the control agent?  Mine shown below is for dhcp6, but i'm sure the config is similar.

$ /usr/sbin/kea-ctrl-agent -c /etc/kea-ctrl-agent.conf

$ cat /etc/kea-ctrl-agent.conf
{
    "Control-agent": {
        "http-host": "10.0.0.1",
        "http-port": 8000,
        "control-sockets": {
            "dhcp6": {
                "socket-type": "unix",
                "socket-name": "/tmp/kea6-ctrl-socket"
            }
        }
    }
}
