Gigabit Ethernet network card setup in Ubuntu 8.04 Server
Today I bought a new network interface for my new server: Conceptronic Gigabit Ethernet card (10€) that has a Realtek RTL8169SC chipset.
I knew that it was compatible with the Ubuntu 8.04 Server that I had installed, so I was a little bit surprised when I plugged it in and it didn’t work 
First I checked and saw that I only had the old card (I knew that by the MAC address 
$ ifconfig
eth1 Link encap:Ethernet HWaddr 00:80:5a:69:b2:d2
inet addr:192.168.0.23 Bcast:192.168.0.255 Mask:255.255.255.0

Next I wanted to see if the system had recognised the card or not so I ran..
$ sudo lshw -C network

Good news! the system recognizes the card but somehow has not managed to bring it up. Let’s help it to know what module to load and under which device name. For that we assign to each network MAC address the module to be loaded in the DRIVERS attribute and assign it a device name in the NAME attribute
$ sudo vim /etc/udev/rules.d/70-persistent-net.rules
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”r8169″, ATTR{address}==”00:80:5a:69:b2:d2″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth0″
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”8139too”, ATTR{address}==”00:50:fc:2d:d7:ba”, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth1″
I also updated the configuration for the interfaces in the /etc/network/interfaces file:
$ sudo vim /etc/network/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 eth0
iface eth0 inet static
address 192.168.0.250
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1auto eth1
iface eth1 inet dhcp
Now we restart the system to get the changes reloaded… I guess there is a less dramatic way to bring the changes life but didn’t feel like thinking much about it and anyway, I’m the only one in the server without anything critical running on it… yet
$ sudo shutdown -r now
And when the system goes back online…
$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:80:5a:69:b2:d2

Everything looks great! 
and finally the server is ready to use the new Gigabit Ethernet connection
