[Kea-users] Kea 1.1-epel conf no longer work with kea 1.6

Hi, 

We have still the problem with the no longer working kea config. In the meantime, the epel repo was update from kea 1.1 to 1.6 so we will see now the same problem for all new installations.

It would be great to get some hints how we can fix this problem. If I can provide any further details, just ask for them.

Best Regards,

Stephan

Btw if it helps, I can provide the debug output of the kea 1.1 and 1.6 

The strange thing is, that I see within the output two different type=60 queries. One match the (I)NODE test and the other doesn't.

But as explained the boot-file-name is set always to the content of the (I)NODE client-class...

Below the output of the working 1.1

Sorry, I tested INODE as well as NODE with the same result.

So it is the SAME within the config, not NODE and INODE within the same file

Hie Stephan,

Is the client-class "INODE" or "NODE"
