Dynamic DNS and DHCP on Fedora ore 9 / Centos 5.2

gnoovy · 02-15-2009, 05:08 AM

hello,

i would like to configure ddns over dhcp on a fedora core 9 or centos 5.2server. So I'm using the rndc.key under /etc to update the dns-zones over dhcp. The reverse-zone-updating is worked correctly but for the forward-zone-update comes the message in /var/log/messages: " client <ip-adress>#1121: update 'linuxnet.local/IN' denied. I don't know why. Here is my dhcp.conf, named.conf and my zone-files: I hope anyone can help me ;-)

Code:

include "/etc/rndc.key";
controls {
inet 127.0.0.1 port 953 allow { 127.0.0.1; 192.168.178.250; } keys { "rndckey"; };
};

options {
	directory "/etc";
	pid-file "/var/run/named/named.pid";
//	forwarders { 192.168.178.254; };
	};


zone "linuxnet.local" {
	type master;
	file "/var/named/linuxnet.local.hosts";
        allow-update { key "rndckey"; 192.168.178.250; };
	};
zone "178.168.192.in-addr.arpa" {
	type master;
	file "/var/named/192.168.178.rev";
        allow-update { key "rndckey"; 192.168.178.250; };
	};

Code:
