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

[Jonathan Elliott]

All,

I’m having some issues with kea-ctrl-agent not creating the sockets required for communicating with the DHCP servers when it is started up.

My setup is as follows:

Ubuntu 23.10 (amd64)
kea-ctrl-agent v2.2.1. installed using apt

Current kea-ctrl-agent configuration :

{
  "Control-agent": {
    "http-host": "192.168.20.254",
    "http-port": 8000,
    "authentication": {
      "type": "basic",
      "realm": "kea-dhcp-server",
      "directory": "/etc/kea",
      "clients": [
        {
          "user": "kea-api",
          "password-file": "kea-api-password"
        }
      ]
    },
    "control-sockets": {
      "dhcp4": {
        "socket-type": "unix",
        "socket-name": "/run/kea/kea4-ctrl-socket"
      },
      "dhcp6": {
        "socket-type": "unix",
        "socket-name": "/run/kea/kea6-ctrl-socket"
      }
    },
    "hooks-libraries": [
    ],
    "loggers": [
      {
        "name": "kea-ctrl-agent",
        "output_options": [
          {
            "output": "/var/log/kea/kea-ctrl-agent.log",
            "pattern": "%-5p %m\n"
          }
        ],
        "severity": "DEBUG",
        "debuglevel": 99
      }
    ]
  }
}

kea-ctrl-agent startup log:

DEBUG DCTL_CONFIG_START parsing new configuration: { "authentication": { "clients": [ { "password-file": "kea-api-password", "user": "kea-api" } ], "directory": "/etc/kea", "realm": "kea-dhcp-server", "type": "basic" }, "control-sockets": { "dhcp4": { "socket-name": "/run/kea/kea4-ctrl-socket", "socket-type": "unix" }, "dhcp6": { "socket-name": "/run/kea/kea6-ctrl-socket", "socket-type": "unix" } }, "hooks-libraries": [  ], "http-host": "192.168.20.254", "http-port": 8000, "loggers": [ { "debuglevel": 99, "name": "kea-ctrl-agent", "output_options": [ { "output": "/var/log/kea/kea-ctrl-agent.log", "pattern": "%-5p %m\n" } ], "severity": "DEBUG" } ] }

However, no sockets re being created in /run/kea.  On the basis of the information provided, can anyone see any configuration issue that might be causing me trouble?

Many thanks,
Jonathan.
