Configurando interfaces de rede

Question

Estou com um problema ao mencionar eth1 e eth0 no meu VMware com o Ubuntu 12.04 Eu tenho 2 pontes e 1NAT e heres meu ifconfig

eth0      Link encap:Ethernet  HWaddr 00:0c:29:7f:05:19  
          inet addr:10.10.10.51  Bcast:10.10.10.255  Mask:255.255.255.0

          Interrupt:19 Base address:0x2024 

eth1      Link encap:Ethernet  HWaddr 00:0c:29:7f:05:23  
          inet addr:192.168.2.60  Bcast:192.168.2.255  Mask:255.255.255.0

          RX bytes:85875 (85.8 KB)  TX bytes:8921 (8.9 KB)
          Interrupt:19 Base address:0x20a4 

eth2      Link encap:Ethernet  HWaddr 00:0c:29:7f:05:2d  
          inet addr:192.168.112.205  Bcast:192.168.112.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fe7f:52d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:283 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:42615 (42.6 KB)  TX bytes:42952 (42.9 KB)
          Interrupt:16 Base address:0x2424 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          collisions:0 txqueuelen:0 
          RX bytes:8632 (8.6 KB)  TX bytes:8632 (8.6 KB)

E aqui estão minhas interfaces

auto lo
iface lo inet loopback

auto eth2
iface eth2 inet dhcp

auto eth0
iface eth0 inet static
address 10.10.10.51
netmask 255.255.255.0
gateway 10.10.10.1

auto eth1
iface eth1 inet static
address 192.168.2.60
netmask 255.255.255.0
gateway 192.168.2.1

e aqui o erro que estou tendo quando runnign /etc/init.d/networking restart

root@ubuntu:/home/advitor# /etc/init.d/networking restart

Failed to bring up eth1.

Eu tentei executar o ifup -v para trazer mais informações sobre eth0 e eth1 e isso me dá isso.

root@ubuntu:/home/advitor# ifup -v eth1
Configuring interface eth1=eth1 (inet)
run-parts --verbose /etc/network/if-pre-up.d
run-parts: executing /etc/network/if-pre-up.d/ethtool

Espero que você possa me orientar sobre como resolver esse problema.

    

Answer 1

Aparentemente, não é mais recomendado usar o /etc/init.d/networking restart (conforme observado por sua saída). Como explicado aqui , a maneira preferida é baixar manualmente e aumentar as interfaces.

Você pode tentar isso e ver se isso ajuda?

ifdown eth0
ifup eth0
ifdown eth1
ifup eth1
