[Kea-users] Problem when using libdhcp_subnet_cmds.so in kea 2.7.7

[Razvan Becheriu]

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 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?
