Hi all,
I have been combing through the docs and the larger internet for help but
I'm stuck. I am trying to add certs to my 2 HA kea servers but adding the
stanza just causes the daemon to fail to start with little explanation safe
for the hook failed. I feel pretty confident that my certs are good, as I
have tested them with the little openssl cli webserver and I don't have the
foggiest clue what else could be wrong. (I do note that by best practice I
should have a keypair for each ca and each dhcp4, but I don't think that is
causing the problem.)
The control agent is running fine on both servers, for example:
INFO CTRL_AGENT_HTTPS_SERVICE_STARTED HTTPS service bound to address
xxx.xxx.xxx.xx2:8000
INFO DCTL_CONFIG_COMPLETE server has completed configuration: listening on
xxx.xxx.xxx.xx2, port 8000, trust anchor CA.pem, cert file ca2_cert.pem,
key file ca2_key.pem, client certs are required, control sockets: d2 dhcp4
dhcp6, requires basic HTTP authentication, 0 lib(s):
INFO CTRL_AGENT_STARTED Kea Control Agent version 2.2.0 started
But here are the relevant parameters
"Control-agent": {
"http-host": "xxx.xxx.xxx.xx2",
"trust-anchor": "CA.pem",
"cert-file": "ca2_cert.pem",
"key-file": "ca2_key.pem",
"cert-required": true,
"http-port": 8000,
"authentication": {
"type": "basic",
"realm": "kea-control-agent",
"clients": [{
"user": "baduser",
"password": "badpassword"
}]
},
The DHCP4 daemon however refuses to start when the 3 TLS parameters are
added and I can not get any more useful logging then what systemctl reports

I feel like I must be missing something simple, but I just can't suss it
out. Any guidance leads or help to be found here?
