sur pc2-2 :

root@pc2-2:/# dhclient eth0
a) Le mac qui apparait est celui du client pc2-2 (42:00:aa:00:00:06)
b) L'adresse est 172.16.2.254 (c'est celle de l'interface eth1 de GW sur le réseau 172.16.2.0/24 )
5) Le serveur reçoit des doublons car les requete dhcp sont des broadcasts, le gw peut relayer depuis plusieurs interfaces ce qui crée des double relay.
6) DHCPDISCOVER,DHCPREQUEST
7) dhcrelay -d -i eth1 192.168.10.10 (l'option -i eth1 demande à GW de ne pas remettre un message déjà traité)
8) plus de doublon, un seul discover, un seul request, fonctionnement normal
