how to reset eth0

[wobbly]

ok i just added 10/100/1000 nic to hda box .... but had onbord enabled
so onbord = eth0
10/100/1000 = eth1

so disabled onbord

rebooted 10/100/1000 is set to eth0... but under hardware is set to eth1 if i set it to eth0 and reboot ....
its back to eth1

ps onbord is no longer in the device list..... just my 10/100/1000 nic

[wobbly]

i just deleted /etc/udev/rules.d/70-persistent-net.rules as root rebooted and all is good
thank you to cpg

now time to try out gigabit speed on my amahi box

[wobbly]

update just added a new gigabit switch and new cat6e cables .... went from 10 meg a sec on 10/100 to 50 meg a sec over gigabit ... love it thanks Amahi

After I disable my onboard lan, rebooted to system. The new NIC is still set to eth1.

Other than the steps above, I also:

1. Change new NIC from eth1 to be eth0 in -Administration-Network control.

2. Delete the /etc/sysconfig/network-scripts/ifcfg-eth1, and update the ifcfg-eth0 with the new NIC's MAC Address.

Then there is no conflict anymore! Gigbit speed!!

sorry new to linux, but how do it delete the ifcfg file, cause it opens in gedit and im not able to change the files

nevermind, figured it out

I tried the above steps, as much as I could find the files in Ubuntu 12.04, but it's still not working. My problem was a little different--I did the install over wifi, but want Amahi to run on eth0. Eth0 is not getting a random IP address and wlan0 is getting the 192.168.1.10 address. I also tried running the install script again with wlan0 off and the network on eth0. It didn't change anything.

How can I reset Amahi to use eth0 instead of wlan0?

Check /etc/network/interfaces and ensure it says eth0. There are several files that hold the eth0, so finding them may be difficult.

It might be worth a reinstall vs spending all your efforts hunting down all occurrences of wlan0. At least that way you would know it's right and will not fail.

sudo gedit /etc/network/interfaces
Changed, wlan0 to eth0. Reboot. Seems to be working.
