Hello Mike, https://wiki.ubuntu.com/WiFiHowto provides a large amount of doc on doing wifi the Unbuntu way (TM), including disabling eth0. If that does not help, you ought to be able to enable and disable interfaces in the configuration file /etc/networking/interfaces (man interfaces for syntax). On straight Debian that file is parsed by the ifup program at boot time. -Adam On Oct 21, 2005, at 12:31 AM, Cretella, Michael A wrote:

Hey all-

I'm running ubuntu 5.10, and trying to understand how the linux bootup process works.. Right now upon bootup I'd like to change two things:

Not ifup eth0 Configure wpa_supplicant to boot up with the right parameters in order to configure itself to the wireless network here.

I think I figured out how to get the wpa_supplicant to work-- I just edited /etc/init.d/wpasupplicant and changed $OPTIONS to the arguments I need in order for it to work.

For disabling eth0 on bootup, I could modify /etc/init.d/networking and change the command "ifup -a" to "ifup wlan0" to just boot up my wlan0 on bootup, but I feel there might be an easier way to do this... Hope you can help!
