Hi Casper - thanks for alerting us to this. The xml syntax is checked and this
should have been caught so this is a (nasty) bug. Could you please report it at:
(if you still have the logs/example zonelist.xml please attached to the issue as
that would be really useful). Also - what version of OpenDNSSEC are you running?
For future reference you can run a standalone tool called ods-kaspcheck
that will check the xml files and produce logs like:
Nov 19 16:44:46 ods ods-kaspcheck: INFO: The XML in /etc/opendnssec/conf.xml is valid
Nov 19 16:44:46 ods ods-kaspcheck: INFO: The XML in /etc/opendnssec/zonelist.xml is valid
Nov 19 16:44:46 ods ods-kaspcheck: INFO: The XML in /etc/opendnssec/kasp.xml is valid
if everything is happy. These are the same checks that are (or should be!) run
by OpenDNSSEC when it loads new xml files while running.
