Question

Estou usando o Ubuntu 12.04, em execução no VMWare. Meu arquivo /etc/network/interfaces consiste em:

# The loopback network interface  
    auto lo  
    iface lo inet loopback  

# The loopback network interface  
    auto lo  
    iface lo inet loopback  


# The primary network interface  
    auto eth0 
    iface eth0 inet static  
    address 192.168.3.15
    netmask 255.255.255.0
    network 192.168.3.0  
    broadcast 192.168.3.255
    gateway 192.168.3.254
    dns-nameservers 8.8.8.8 

    auto eth1
    iface eth1 inet static  
    address 192.168.3.40
    netmask 255.255.255.0
    network 192.168.3.0  
    broadcast 192.168.3.255
    gateway 192.168.3.15
    dns-nameservers 192.168.1.15 

Eu executei o comando /etc/init.d/networking restart que retornou isso:

*Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces  
*Reconfiguring network interfaces...
