probleme DNS avec yum, vlc, wget

betsubetsu · 17 juin 2009

Depuis que j'ai upgradé mon pc vers F11, j'ai des problemes DNS. J'ai un server DNS sous F10 et d'autres pc sous F10 qui n'ont, eux, pas de soucis.

Lorsque je fais un 'yum update', j'ai les message suivants:

# yum update

et avec wget:

$ wget http://fedora.tu-chemnitz.de/pub/linux/rpmfusion/nonfree/fedora/updates/11/x86_64/repodata/repomd.xml
--2009-06-16 13:29:41--  http://fedora.tu-chemnitz.de/pub/linux/rpmfusion/nonfree/fedora/updates/11/x86_64/repodata/repomd.xml
Resolving fedora.tu-chemnitz.de... failed: Name or service not known.
wget: unable to resolve host address `fedora.tu-chemnitz.de'

Pourtant je n'ai pas de probleme pour resoudre les noms lorsque je navigue sur internet avec firefox et la commande host me trouve les bonnes addresses ip:

$ host vip8.yacast.fr
vip8.yacast.fr has address 193.201.103.108
$ host fedora.tu-chemnitz.de
fedora.tu-chemnitz.de has address 134.109.228.1
$ host linuxdownload.adobe.com
linuxdownload.adobe.com is an alias for linuxdownload.wip3.adobe.com.
linuxdownload.wip3.adobe.com has address 192.150.18.37

dans mon /etc/resolv.conf, j'ai ceci:

domain xxx.yyy.fr
search xxx.yyy.fr
nameserver 10.0.21.17
nameserver aaa.bbb.156.13

et si j'intervertis les 2 dernières lignes comme ceci:

domain xxx.yyy.fr
search xxx.yyy.fr
nameserver aaa.bbb.156.13
nameserver 10.0.21.17

alors les problemes ci-dessus disparaissent mais je ne resoud plus les noms des machines de mon réseau local.

Quelqu'un aurait-il une idee?

Merci d'avance.

Quel est ce 10.0.21.17, DNS local ?
Quel est ce aaa.bbb.156.13 ? FAI autre DNS sur réseau privé.

betsubetsu · 17 juin 2009

aaa.bbb.156.13 est un serveur DNS de la fac
10.0.21.17 est mon serveur DNS privé pour mes machines sur le LAN.

pmarion · 17 juin 2009

Peux-tu faire
host -v nom_host_a_resoudre
dans les deux cas (lignes inversées ou non)

Essaie aussi de n'utiliser que ton DNS mais en lui spécifiant un forward sur l'aure DNS

betsubetsu · 17 juin 2009

Dans les 2 cas, j'obtiens quelque chose comme ceci:

$ host -v vip8.yacast.fr

et si je supprime la ligne 'nameserver aaa.bbb.156.13' de /etc/resolv.conf et que je mets aaa.bbb.156.13 comme forwarder, je ne resoud rien.

Même problème, une fois F11 mise à jour. Ca ne vient pas des DNS. Une F11 installée sans mise à jour fonctionne par contre sans problème.
