Et sur la machine qui marche que te donne route -n ? 
Que dises les logs de SSH de l'ancienne ?

Quelles sont les adresses IP et les masques que tu
utilises pour ces deux machines ?



Une qui marche:

eric@eric:~$ more /etc/network/interfaces
# This file describes the network interfaces
available on your system
# and how to activate them. For more information,
see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
       address 192.168.1.1
       netmask 255.255.255.0

Est-ce que les ping fonctionne de 192.168.1.2 vers 192.168.1.1 ? 


oui


Utilises tu iptables ?
iptables -L pout lister les regles 
Sur machine 192.168.1.2 execute nmap pour voir les
ports ouverts :
nmap -P0 192.168.1.1 Avec ça on devrait avancer
