I've set up dhcp + bind9 ddns with allow updates by key
I keep getting this 'update unsuccessful' messages on syslog because the name already exists (from the previous dhcp renew) and I would like to confirm that those are informative and perfectly normal and, therefore, can be ignored by logcheck.
If the dhcp changed the ip of the lease, would the record be correctly updated? If not, how can I allow the replacement a name in use? And from the point of view of security, should I?
Code:
