Re: DNS problem update denied

Hello,

It seems that the servers with IP 190.168.1.213 and 190.168.1.245 try to update the reverse zone 1.168.190.in-addr.arpa.

Before BIND8, the only security between primary and secondary zones was IP iddress checking.

Starting with BIND8, zone transfers and updates betweek primary and master DNS servers can be made more secure using cryptographic keys.

Here, your DNS server is rejecting updates from the IP addresses found in the syslog.

If you want further explanations, please post your /etc/named.conf.

Good luck.
