DDNS & DHCP

Hi all,

I'm trying to configure DHCP to make it update DNS records whenever
a new IP address is assigned... but no way to get it working!

1. As root, I've created the key to be used between named and dhcpd
   for dynamic DNS updates:

   dnssec-keygen -a HMAC-MD5 -b 512 -n HOST dhcp-updater


2. Then, I've modified /etc/dhcpd.conf as following:

   ...
   allow client-updates;

   ddns-updates on;
   ddns-domainname "agamura.com.";
   ddns-rev-domainname "in-addr.arpa.";
   ddns-update-style interim;

   key dhcp_updater {
        algorithm hmac-md5;
        secret "GC2kwEdJxhMol2e...;
   };

   zone agamura.com. {
        primary 192.168.1.1;
        key dhcp_updater;
   }

   zone 1.168.192.in-addr.arpa. {
        primary 192.168.1.1;
        key dhcp_updater;
   }
   ...

3. and /etc/named.conf as following:

   ...
   acl "home" { 192.168.1.0/24; 127.0.0.1; };

   options {
        directory "/var/named";
        pid-file "/var/run/named/named.pid";
        dump-file "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        allow-query { "home"; };
        forwarders { 195.186.1.111; 195.186.4.111; };
    };

    ...
    key dhcp_updater {
        algorithm hmac-md5;
        secret "GC2kwEdJxhMol2e...;
    };

    zone "1.168.192.in-addr.arpa" {
        type master;
        file "1.168.192.in-addr.arpa.zone";
        notify yes;
        allow-update { key dhcp_updater; };
    };

    zone "agamura.com" {
        type master;
        file "agamura.com.zone";
        notify yes;
        allow-update { key dhcp_updater; };
    };   

4. Finally, I've restarted named and dhcpd.

That is it! Am I missing something important to get this
stuff working (I'm running FC3)?

Thanks for your help,
j3d.
