.SH CONFIGURATION EN TEMPS QUE SERVEUR FAISANT AUTORITÉ
|
||||
.PP
|
||||
Configurer dnsmasq pour agir en temps que serveur DNS faisant autorité est
|
||||
compliqué par le fait que cela implique la configuration de serveurs DNS
|
||||
externes pour mettre en place la délégation. Seront présentés ci-dessous trois
|
||||
scénarios de complexité croissante. Le pré-requis pour chacun de ces scénarios
|
||||
est l'existence d'une adresse IP globalement disponible, d'un enregistrement de
|
||||
type A ou AAAA pointant vers cette adresse, ainsi que d'un serveur DNS externe
|
||||
capable d'effectuer la délégation de la zone en question. Pour la première
|
||||
partie de ces explications, nous allons appeller serveur.exemple.com
|
||||
l'enregistrement A (ou AAAA) de l'adresse globalement accessible, et
|
||||
notre.zone.com la zone pour laquelle dnsmasq fait autorité.
|
||||
|
||||
La configuration la plus simple consiste en deux lignes de configuration,
|
||||
sous la forme :
|
||||
.nf
|
||||
.B auth-server=serveur.exemple.com,eth0
|
||||
.B auth-zone=notre.zone.com,1.2.3.0/24
|
||||
.fi
|
||||
|
||||
ainsi que deux enregistrements dans le DNS externe :
|
||||
|
||||
.nf
|
||||
serveur.exemple.com A 192.0.43.10
|
||||
notre.zone.com NS serveur.exemple.com
|
||||
.fi
|
||||
|
||||
eth0 est l'interface réseau externe sur laquelle dnsmasq écoute, dont l'adresse
|
||||
IP (globalement accessible) est 192.0.43.10.
|
||||
|
||||
A noter que l'adresse IP externe peut parfaitement être dynamique (par exemple
|
||||
attribuée par un FAI via DHCP ou PPP). Dans ce cas, l'enregistrement de type A
|
||||
doit être lié à cet enregistrement dynamique par l'une ou l'autre des techniques
|
||||
habituelles de système DNS dynamique.
|
||||
|
||||
Un exemple plus complexe mais en pratique plus utile correspond au cas où
|
||||
l'adresse IP globalement accessible se trouve dans la zone pour laquelle
|
||||
dnsmasq fait autorité, le plus souvent à la racine. Dans ce cas nous avons :
|
||||
|
||||
.nf
|
||||
.B auth-server=notre.zone.com,eth0
|
||||
.B auth-zone=notre.zone.com,1.2.3.0/24
|
||||
.fi
|
||||
|
||||
.nf
|
||||
notre.zone.com A 1.2.3.4
|
||||
notre.zone.com NS our.zone.com
|
||||
.fi
|
||||
|
||||
L'enregistrement A pour notre.zone.com est dorénavant un enregistrement "colle"
|
||||
qui résoud le problème de poule et d'oeuf consistant à trouver l'adresse IP
|
||||
du serveur de nom pour notre.zone.com lorsque l'enregistrement se trouve dans
|
||||
la zone en question. Il s'agit du seul rôle de cet enregistrement : comme dnsmasq
|
||||
fait désormais autorité pour notre.zone.com, il doit également fournir cet
|
||||
enregistrement. Si l'adresse externe est statique, cela peut-être réalisé par
|
||||
le biais d'une entrée dans
|
||||
.B /etc/hosts
|
||||
ou via un
|
||||
.B --host-record.
|
||||
|
||||
.nf
|
||||
.B auth-server=notre.zone.com,eth0
|
||||
.B host-record=notre.zone.com,1.2.3.4
|
||||
.B auth-zone=notre.zone.com,1.2.3.0/24
|
||||
.fi
|
||||
|
||||
Si l'adresse externe est dynamique, l'adresse associée à notre.zone.com doit
|
||||
être dérivée de l'interface correspondante. Cela peut être fait en utilisant
|
||||
.B interface-name
|
||||
Sous la forme :
|
||||
|
||||
.nf
|
||||
.B auth-server=notre.zone.com,eth0
|
||||
.B interface-name=notre.zone.com,eth0
|
||||
.B auth-zone=notre.zone.com,1.2.3.0/24
|
||||
.fi
|
||||
|
||||
La configuration finale rajoute à cette base un serveur DNS secondaire. Il
|
||||
s'agit d'un autre serveur DNS qui apprend les données DNS de la zone en
|
||||
effectuant un transfert de zone, et qui joue le rôle de serveur de secours
|
||||
au cas où le serveur principal devenait inaccessible. La configuration
|
||||
de ce serveur secondaire sort du cadre de cette page de manuel. Les éléments
|
||||
de configuration à rajouter dans dnsmasq sont les simples :
|
||||
|
||||
.nf
|
||||
.B auth-sec-servers=secondaire.monfai.com
|
||||
.fi
|
||||
|
||||
et
|
||||
|
||||
.nf
|
||||
notre.zone.com NS secondaire.monfai.com
|
||||
.fi
|
||||
|
||||
L'addition d'une option auth-sec-servers active les transferts de zone dans
|
||||
dnsmasq, ce qui permet au serveur secondaire de venir collecter les données
|
||||
DNS. Si vous souhaitez restreindre l'accès à ces données à des hôtes
|
||||
spécifiques, vous pouvez le faire via :
|
||||
|
||||
.nf
|
||||
.B auth-peer=<adresse IP du serveur secondaire>
|
||||
.fi
|
||||
|
||||
Dnsmasq joue le rôle de serveur faisant autorité pour les domaines in-addr.arpa
|
||||
et ipv6.arpa associés aux sous-réseaux définis dans la déclaration de zone
|
||||
auth-zone, ce qui fait que les requêtes DNS inversées (de l'adresse vers
|
||||
le nom) peuvent-simplement être configurées avec un enregistrement NS
|
||||
adéquat. Par exemple, comme nous définissons plus haut les adresses
|
||||
1.2.3.0/24 :
|
||||
.nf
|
||||
3.2.1.in-addr.arpa NS notre.zone.com
|
||||
.fi
|
||||
|
||||
Veuillez noter que pour l'instant, les zones inverses ne sont pas
|
||||
disponibles dans les transferts de zone, donc il est inutile de configurer
|
||||
de serveur secondaire pour la résolution inverse.
|
||||
|
||||
.PP
|
||||
Lorsque dnsmasq est configuré en temps que serveur faisant autorité,
|
||||
les données suivantes sont utilisées pour peupler la zone considérée :
|
||||
.PP
|
||||
.B --mx-host, --srv-host, --dns-rr, --txt-record, --naptr-record
|
||||
, pour autant que les noms des enregistrements se trouvent dans la zone en
|
||||
question.
|
||||
.PP
|
||||
.B --cname
|
||||
pour peu que le nom soit dans le domaine. Si la cible du CNAME n'est
|
||||
pas pleinement qualifiée, alors elle est qualifiée avec le nom de la
|
||||
zone pour laquelle le serveur fait autorité.
|
||||
.PP
|
||||
Les adresses IPv4 et IPv6 extraites de /etc/hosts (et
|
||||
.B --addn-hosts
|
||||
) ainsi que les options
|
||||
.B --host-record
|
||||
fournissant des adresses situées dans l'un des sous-réseaux spécifiés dans
|
||||
.B --auth-zone.
|
||||
.PP
|
||||
Adresses spécifiées par
|
||||
.B --interface-name.
|
||||
Dans ce cas, l'adresse n'est pas limitée à l'un des sous-réseaux donné dans
|
||||
.B --auth-zone.
|
||||
|
||||
.PP
|
||||
Les adresses de baux DHCP, si l'adresse est située dans l'un des sous-réseaux de
|
||||
.B --auth-zone
|
||||
OU dans une plage DHCP construite. Dans le mode par défaut, où le bail
|
||||
DHCP a un nom non qualifié, et éventuellement pour un nom qualifié construit
|
||||
via
|
||||
.B --domain
|
||||
, alors le nom dans la zone faisant autorité est construit à partir du nom
|
||||
non qualifié et du nom de domaine de la zone. Cela peut on non être égal
|
||||
celui fourni par
|
||||
.B --domain.
|
||||
Si l'option
|
||||
.B --dhcp-fqdn
|
||||
est fournie, alors les noms pleinemenet qualifiés associés aux baux DHCP
|
||||
sont utilisés, dès lors qu'ils correspondent au nom de domaine associé

à la zone.
