Good day,
I have 2 network cards on my Ubuntu 9.1 server. The 1st one is
configured on my Domain, DHCP enabled (with reservation on the dhcp
server).
The 2nd one, is there, when I ifconfig but its not displayed in
/etc/network.interface, im looking to configure eth0.
Output of /etc/interface
root at Washington:/etc/network# cat 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 eth1
iface eth1 inet dhcp
Ouput of ifconfig:
eth0 Link encap:Ethernet HWaddr $MACADDR
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

eth1 Link encap:Ethernet HWaddr $MACADDR
inet addr:XXX.XXX.XXX.XXX Bcast:XXX.XXX.XXX.XXX
Mask:255.XXX.XXX.XXX
inet6 addr: $IPV6 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX bytes:1039941534 (1.0 GB) TX bytes:75767637 (75.7 MB)
Memory:da060000-da080000
I would like to give a testing ip address to ETH0, Do I have to insert
anything in interface? Like this example?
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.3.90
gateway 192.168.3.1
netmask 255.255.255.0
network 192.168.3.0
broadcast 192.168.3.255
Thanks.
