Résolution DNS ?

Bonjour à tous,

Un truc bizarre avec une debian/sparc... J'ai installé un DNS local
configuré correctement. Mon fichier host ne contient rien et toutes
les résolutions se font au travers du DNS local.

Root bohr:[/etc/bind] > ps auwx | grep named
bind 31191 0.0 0.3 15776 3328 ? Ss 19:14 0:00
/usr/sbin/named -u bind

Question : sachant que le DNS est boen inactif, comment cette
résolution (locale) peut-elle se faire ? Pour info :

Root bohr:[/etc/bind] > cat /etc/hosts
127.0.0.1 localhost

# Serveurs
213.41.140.153 bohr.systella.fr bohr
192.168.0.128 lagrange.systella.fr lagrange
Root bohr:[/etc/bind] > cat /etc/nsswitch.conf
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd: compat files
group: compat files
shadow: compat files

hosts: files dns
networks: files dns

protocols: db files
services: db files
ethers: db files
rpc: db files

netgroup: nis
Root bohr:[/etc/bind] >

Une idée, parce que je sèche...

Cordialement,
