Andrei,
Thanks for the answer. You were correct. I thought I grabbed the el9
files, but they were the el8.
I am now getting an error that the CmdHttpListner is not starting because
multithreading is disabled. In searching I can not find any reference in
the ISC documentation about the cmdhttplistener or how to configure it.
A Google search did come up with this snippet:
{
"dhcp4": {
"cmdhttplistner": {
"enabled": true,
"listen-interface": "eth0",
"listen-port": 8080,
"listen-address": "0.0.0.0",
"auth-key": "your_auth_key"
}
}
}
But I can't find any other reference to it.
Is there a way to make sure that multithreading is enabled?
I see that the kea-ctrl-agent will be merged with the kea-dhcpx service
sometime after 2.6. Will all the current curl commands be available once
that is in place? The list of commands that I saw left out the
ha-maintenance-cancel and start commands.
Thanks,
Scott
