04 and the network card is not supported by default kernel. So, I upgrade kernel to 3.2 and it support it. However, every time I reboot machine, need to sudo ifup eth0 to bring up it.

How can I modify some config to auto bring up eht0? (not write in /etc/rc.local, cause I mount NFS on /etc/fstab, it need to mount first than rc.local).

Answer 1

In Ubuntu you have to edit /etc/network/interfaces and set default configuration data for every network interface on your system.

Put both auto and your interface name on a separate line before your interface configuration in order to bring it up at startup.

Example: When your configuration is like this

iface eth0 inet static
address 192.168.1.5
netmask 255.255.255.0
gateway 192.168.1.254

You have to change it to this

auto eth0
iface eth0 inet static
address 192.168.1.5
netmask 255.255.255.0
gateway 192.168.1.254

Network card configuration

you can eidt /etc/sysconfig/network-scripts/ifcfg-eth0 file. serach ONBOOT with file content. and change ONBOOT=no to ONBOOT=yes.
