Problème DHCP Failover

Bonjour,

Je suis en train d'installer un failover pour un dhcp.
J'ai configuré les 2 ordinateurs mais le serveur principal me renvoi une erreur dans les fichier log
(Les deux machines tourne sous debian 4.0 )


vim /var/log/syslog

Dec 11 18:36:28 localhost dhcpd: failover peer dhcp_failover: I move from communications-interrupted to startup
Dec 11 18:36:28 localhost dhcpd: failover peer dhcp_failover: I move from startup to communications-interrupted

Voici mon fichier de conf du serveur :

#
ddns-update-style none;
ddns-updates off;

allow unknown-clients;

# option definitions common to all supported networks...
option domain-name "DebianRoom.org";
#option domain-name-servers 192.168.1.1;
#option routers 192.168.1.1;

# delai du bail en seconde
default-lease-time 600;


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



#dhcp failover
failover peer "dhcp_failover"{
primary;
address 192.168.1.100;
port 519;
peer address 192.168.1.101;
peer port 519;
mclt 3600;
split 128;
}

failover peer "dhcp_failover" state {
my state partner-down;
}


subnet 192.168.1.0 netmask 255.255.225.0 {
pool {
failover peer "dhcp_failover";
deny dynamic bootp clients;

range 192.168.1.51 192.168.1.60;
}
}

Merci d'avance a ceux qui pourront m'aider
