<html><p>Hello,</p><p>my kea-dhcp-ddns Service ( version: 3.1.6 ) doesn't start. </p><p>Here is the error-Message : </p><p> DCTL_CONFIG_FILE_LOAD_FAIL DhcpDdns reason: use of clear text TSIG 'secret' is NOT SECURE (/etc/kea/tsig-keys.json:5:18)<br>Service failed: Could Not load configuration file: use of clear text TSIG 'secret' is NOT SECURE (/etc/kea/tsig-keys.json:5:18)</p><p>I thought, that i must use secret-file to correct this, but i doesn't find anything for the syntax for the file. (It was nice to add this in the Document, how to make this correct, so that the kea-dhcp-ddns Service will run .)</p><p>Best regards</p><p>Ralf</p><p> </p></html>
