[Kea-users] Problem with kea-dhcp6

[Anton Kiryushkin]

Hello.

I have a simple configuration file:

{
"Dhcp6": {
    "interfaces-config": {
        "interfaces": [ "eth0" ]
    },
    "control-socket": {
        "socket-type": "unix",
        "socket-name": "/tmp/kea-dhcp6-ctrl.sock"
    },
    "lease-database": {
        "type": "memfile",
        "lfc-interval": 3600
    },
    "expired-leases-processing": {
        "reclaim-timer-wait-time": 10,
        "flush-reclaimed-timer-wait-time": 25,
        "hold-reclaimed-time": 3600,
        "max-reclaim-leases": 100,
        "max-reclaim-time": 250,
        "unwarned-reclaim-cycles": 5
    },
    "renew-timer": 1000,
    "rebind-timer": 2000,
    "preferred-lifetime": 3000,
    "valid-lifetime": 4000,
    "option-data": [
        {
            "name": "dns-servers",
            "data": "2001:db8:1::3"
        }
    ],
    "subnet6": [
        {
            "subnet": "2001:db8:1::/64",
            "pools": [ { "pool": "2001:db8:1::/64" } ]
        }
    ]
},
"Logging":
{
  "loggers": [
    {
        "name": "kea-dhcp6",
        "output_options": [
            {
                "output": "/var/log/kea/dhcp6.log"
            }
        ],
        "severity": "DEBUG",
        "debuglevel": 20
    }
  ]
}
}

But.
When I tried to start it I saw the text below:

Why it wrote about DHCPSRV_NO_SOCKETS_OPEN except for DHCP6?
Why didn't open any socket for DHCP6?
Of course, I have an address from the subnet 2001:db8:1 on eth0.
