I would like to replace my existing ISC-DHCP HA installation with a KEA HA solution, as the ISC-DHCP server has reached the end of its support life.
The kea-dhcp4-server works perfectly![:)]( "Smile")
. But I cannot get the high availability with the mode “hot-standby” and the variant “memfile” to work. ![:(]( "Sad")
I probably have an understanding problem in the configuration of kea-ctrl-agent.conf . Unfortunately, I have not found a solution for similar errors (which I have searched for on the Internet). I have already set the debug level to maximum, but unfortunately this does not give me a clear error message. Perhaps I also lack a certain basic knowledge. I would be very happy to receive support with the error diagnosis or suggestions for improved diagnosis![:-)]( "Smile")

Please do not be confused by the names used, they are both x64 installations.
