Dhcp is not dynamically updating dns
i'm trying to dynamically update DNS records when DHCP give out addresses.but even though I have specified allow-update with a key in /etc/bind/local and specified the same key in /etc/dhcp/ i also tried to set a ip address in allow update instead, but this doesen't seem to work either. tail -f /var/log/syslog client 127.0.0.1#53398: update 'dirks.crtn/IN' denied due to allow-query dhcpd: unable to add forward map from sysadmin.We will start by copying the files so we have a backup remaining if anything goes wrong: 1.1 Copy the zone database files: We now need to add the key to the bind configuration and tell it what zones that we want it to allow updates on.
If you have followed the steps in my previous post you might have your zone database files in /etc/bind/zones.
In order to do so, I need to be able to facilitate updating DNS records from clients that do and do not support dynamic DNS record registration.
Active Directory/DNS is running on Server 2012 R2 in 2012 R2 forest/domain functional levels.
When a DHCP server leases an address to a client, it can also perform registration of that computer’s address in DNS.
DNS registration ensures that the addresses configured in the DNS zone match the IP addresses leased by the DHCP server.
The scripts above are rather lengthy, so I won't post them here, but the basic steps are: Generate a keytab using ktutil.
