Greetings,
<div><br>
<div><br>
</div>
<div>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
<a href="http://libdhcp_subnet_cmds.so">libdhcp_subnet_cmds.so</a> library. </div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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. </div>
<div> </div>
<div>Can you let me know if I missed anything? </div>
