Dynamic DNS and DHCP on Fedora ore 9 / Centos 5.2
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:
$ORIGIN .
$ttl 38400
linuxnet.local. IN SOA centos-server.linuxnet.local. root.linuxnet.local. (
