DDNS

[Charlie B]

Hello,
Using:
BIND 9.3.4
DHCP 3.0.3

I have configured dns and dhcp, ddns looks to be working successfully
however I have noticed that dns is not writing the records to the zone file
until a restart.  Is this normal or how best would I discover the problem
behind this issue

parts named.conf

controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; 10.0.0.10; } keys { "rndckey"; "dhcpdupdate";};
};

key dhcpupdate {
        algorithm hmac-md5;
        secret "<blah>";
};


       zone "0.254.11.10.in-addr.arpa" {
                type master;
                file "/var/named/0.254.11.10.in-addr.arpa.zone";
                allow-update { key dhcpupdate; };
        };


parts dhcpd.conf

key dhcpupdate {
        algorithm hmac-md5;
        secret "<blah>";
};
