Hola a todos: Sucede que configure el DNS para que acepte actualizaciones dinamicas del DHCP, una vez configurado este, me conecte utilizando nsupdate y cree un registro en ambas zonas sin ningun problema, ahora cuando voy a la configuracion del DHCP le agrego estas lineas,

include "/etc/rndc.key";
zone localdomain. {
primary 127.0.0.1;
key rndc-key;
}
zone 1.168.192.in.addr.arpa. {
primary 127.0.0.1;
key rndc-key;
}
zone mi.dominio. {
primary 127.0.0.1;
}

y trato de reiniciar el serivicio DHCP este me da error, es decir no se inicia.
Agradeceria alguna ayuda al respecto
Gracias

Lo que publicas tiene un error. No existe la zona 1.168.192.in.addr.arpa, sino 1.168.192.in-addr.arpa. Es decir, pusiste un punto en lugar de un guión después de '1.168.192.in'.

Es factible tengas otros errores de dedo (casi siempre un ; faltante en alguna líena). Corrige lo anterior y por favor, ejecuta lo siguiente para generar registros en /var/log/messages que indiquen en donde tienes más posibles errores:



Publica el contenido en este espacio.

De ser posible, por favor también publica todo el contenido de /etc/dhcp/dhcpd.conf.

Gracia Joel por su respuesta
Efectivamente existia un error en la zona, en vez de 1.168.192.in.addr.arpa, es 1.168.192.in-addr.arpa.
Ahora una vez corregido lo anterior y ejecutado el comando service dhcpd restart ; tail -80 /var/log/messages |grep dhcp devuelve los registros siguientes

Lo que publicas indica que hay otro DHCP operando en tu red local. Ejemplo:



Te sugiero quites server-name "servdhcp"; a menos que haya un DNS que resuelva servdhcp con una IP. Server name se calcula automáticamente basado sobre el nombre de anfitrión del sistema (mismo que igualmente debe ser un FQDN).

Hola Joel, gracias por su respuesta, he tardado en escribir por causas ajenas, aprovecho el momento para decirle que en un momento existieron dos servidores DHCP uno en windows y el otro en CentOS como les dije, desabilite el de windows y solo tengo en produccion el de CentOS, ahora bien, me surge la duda porque el servidor DHCP esta en una maquina diferente a donde tengo instalado el servicio DNS, tendria algo que ver en que no levante el servicio DHCP, tendrian que estar los servicos en el mismo host

Desde ya gracias por su ayuda
