Dynamic DNS (Bind) e DHCP

[Caio Abreu Ferreira <idic@terra.com.br>]

	Lista

	Estou tentando configurar o servidor DHCP e o servidor DNS (Bind)
para que os dois trabalhem junto, DDNS (Dynamic DNS). Quando uma nova estação
é acrescentada na rede e assume um novo IP (DHCP), um novo "registro" é
acrescentado no DNS (Bind). Para isso estou seguindo alguns textos[1]/[2] que
tenho encontrado na internet.

	Informações técnica.

- DNS Server - 192.168.0.5 (master) e 192.168.0.6 (slave)
- DHCP Server - 192.168.0.7
- Domínio - particula.local

	Até agora eu fiz o seguinte.

##### A - cat etc/rndc.key #####
	key "rndc-key" {
       		 algorithm hmac-md5;
       		 secret "FiPdAfSwPyMCYI8Ck1hDTg==";
	};

##### B - dhcpd.conf #####
	authoritative;
	ddns-update-style interim;
	ddns-updates on;
	ddns-domainname "particula.local";
	ddns-rev-domainname "0.168.192.in-add.arpa";

	key "rndc-key" {
       		 algorithm hmac-md5;
       		 secret "FiPdAfSwPyMCYI8Ck1hDTg==";
	};

	zone particula.local {
       		 primary 192.168.0.5;
       		 key rndc-key;
	}

	zone 0.168.192.in-addr.arpa {
       		 primary 192.168.0.5;
       		 key rndc-key;
	}

	default-lease-time 600;
	max-lease-time 7200;

	option  domain-name "particula.local";
	option  domain-name-servers 192.168.0.5, 192.168.0.6;

	subnet 192.168.0.0 netmask 255.255.255.0 {
       		 range 192.168.0.100 192.168.0.127;
       		 option routers 192.168.0.2;
       		 option  domain-name "particula.local";
       		 option  domain-name-servers 192.168.0.5, 192.168.0.6;
       		 option broadcast-address 192.168.0.255;
	}

##### named.conf (master) #####
	key "rndc-key" {
	        algorithm hmac-md5;
	        secret "FiPdAfSwPyMCYI8Ck1hDTg==";
	};

	zone "particula.local" {
	        type master;
	        file "master/db.particula.local";
	        allow-transfer { 192.168.0.6; };
		notify yes;
	};

	zone "0.168.192.in-addr.arp" {
	        type master;
	        file "master/db.0.168.192.in-addr.arpa";
	        allow-update { key rndc-key; };
	};
 
	Quando o servidor de DHCP é inicializado estão aparecendo as
seguintes mensagens de erro.

	Alguem na lista por acaso já implementou esse tiopo de solução DDNS?

Obrigado.
