Dos Tarjetas de Red

[Felipe Fernandez <felipe@editateide.com>]

Tengo un p4 con dos tarjetas de red, kernel 2.6.8 y debian stable

8139too Fast Ethernet driver 0.9.27
ACPI: PCI interrupt 0000:01:09.0[A] -> GSI 17 (level, low) -> IRQ 177
eth0: RealTek RTL8139 at 0xb800, 00:05:1c:00:5e:5f, IRQ 177
eth0:  Identified 8139 chip type 'RTL-8139C'
8139cp: 10/100 PCI Ethernet driver v1.2

Esto me lo sale con dmesg pero la interface eth1 no aparece por ningun sitio

el fichero /etc/network/interfaces es el que sigue:

# 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 eth0 eth1
iface lo inet loopback

# The primary network interface
iface eth0 inet static
        address 172.26.0.11
        netmask 255.255.255.0
        network 172.26.0.0
        broadcast 172.26.0.255
        gateway 172.26.0.1

        # dns-* options are implemented by the resolvconf package, if

¿Alguna ayuda?
