Adding second network card to Ubuntu 8.0.10
I added a cnet card into my system, it does not show up in ifconfig.
I tried : lspci and see my net card there, ifconfig -a, sees the two, eth1 and eth0
edit /etc/network/interfaces, add following:
iface eth1 inet static
sudo /etc/init.d/networking restart
you can see now eth1 in the ifconfig even without -a.
Change from dhcp to static ip
this works for me
