Hi Razvan,
I run the API and now I got the return code “0” which according to the document
should mean success. However, when I checked the kea-dhcp6.conf file on the
target host, I still see the original configuration. I restarted the kea-dhcp6
service, but the configuration still hasn’t changed. I also tested the
“subnet6-del” command and observed the same behaviors.
Did I miss something else?

Hi Raven,
Thank you for your response! I run the curl command from my laptop which is in
the same LAN as both kea hosts, both have the control-agent running. I just
tried to put standby node kea02 with .112 IP in “in-maintenance” mode and tried
to send API again, but still got the same error.

Hi,
I think you are sending the command to the HA endpoint. That is reserved for HA
commands.
Please use the control channel endpoint or CA endpoint instead.

Subject: [Kea-users] Problem when using libdhcp_subnet_cmds.so in kea 2.7.7
Greetings,
I have upgraded my kea lab from 2.6.1 to 2.7.7 and installed the package for
hooks. Now I am testing the
libdhcp_subnet_cmds.so<http://libdhcp_subnet_cmds.so/> library.
But I found that I could only run those status check commands successfully, but
I am not able to modify any configurations as you can see the examples below.
It happened to all the commands which could modify the configuration.
I adjusted the format of my arguments to match the example in your document,
but it didn’t work. I added the -u option to curl as the root user, but still
not working. Instead of running the curl command remotely, I run it in the same
Linux host but still the same. I tried to Google this error but couldn’t find
any match including your kea message documentation. I run the curl command
against both primary and standby nodes, but still not working.
When I used -v mode for curl command, I can see it does return code 200, so I
don’t think it’s other issue than kea hook function itself.
Can you let me know if I missed anything?
