serveur dhcp (dhcp3-server)

[Aux Saveurs Gourmandes <guy88@freegates.be>]

Je tente de configurer un serveur dhcp en sarge et j'ai quelques problemes
Il refuse absolument de se lancer alors que je reprend le fichier de 
conf dqui etait sur la meme machine mais en stable (j'ai completement 
reinstalle la machine en sarge pas un upgrade pour d'autres raisons).
il doit donner des adresses sur 3 interfaces eth0  192.168.0.1 eth2 
192.168.1.1 eth3 192.168.2.1
Il rale sur la ligne ddns-update-style ad-hoc.
Merci de votre aide

Voici le contenu de mon dhcpd.conf
# dhcpd.conf

option subnet-mask 255.255.255.0;
default-lease-time 600;
ddns-update-style ad-hoc;
max-lease-time 7200;

# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;

# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
