[Kea-users] Kea HA with self signed certs

[Darren Ankney]

Hi,

You might try using "curl" as shown here:

https://kea.readthedocs.io/en/kea-2.4.1/arm/ctrl-channel.html#using-the-control-channel

I know very little about SSL, but `--insecure` added to the curl
command line will cause it to not check validity of certificates.  You
can also specify cert files on the command line. This should let you
test your certificate setup more easily I'd think.

Thank you,
Darren Ankney

Would indicate your server config didn’t set or is set to true and you did not provide one in the sample command line.  If you don’t require client cert for authentication, you can set to false in kea-ctl-agent.conf.

For this project alone I worked with the folks on reddit to develop a script for creating the self signed certs. https://www.reddit.com/r/openssl/comments/170r9ko/creating_self_signed_cert_for_kea_encryption/?utm_source=share&utm_medium=web2x&context=3 so I assume the error is somewhere there. But I don't understand the reply when I run kea-shell.
