Shares du NAS et configuration de linux

Configuration des UID et GID

Pour paramétrer correctement les groupes et les identifiants pour les droits d'accès les userid et les groupid doivent être identiques côté server et client.

Configuration du domaine

Le client et le serveur doivent être sur le même domaine.

Pour vérifier ça exécuter la commande

maitre@cahute:~$ sudo nfsidmap -d
beafrancois.fr

Si ça n'est pas la même chose sur un des PC, il faut modifier le fichier /etc/hostname:

<hostname>.beafrancois

sur le nas

sur le nas les répertroires suivants sont exportés en nfs:

/etc/exports

/export/famille            192.168.1.0/255.255.255.192(rw,insecure,no_subtree_check)
/export/multimedia         192.168.1.0/255.255.255.192(rw,insecure,no_subtree_check)
/export/partage            192.168.1.0/255.255.255.192(rw,insecure,no_subtree_check)
/export/home/beatrice      192.168.1.0/255.255.255.192(rw,insecure,no_subtree_check)
/export/home/francois      192.168.1.0/255.255.255.192(rw,insecure,no_subtree_check)
