How to stop eth0 interface on boot before dhcpcd lease

[sentralorigin]

I think I am running Gentoo though I have a vanilla kernel.

Whenever I boot up my computer, it starts ath0 and eth0 (the wireless card and the ethernet interface). How do I stop the eth0 from starting? Basically I want to do "ifconfig eth0 down" at boot before it starts connecting to anything automatically. I tried rc-update del net.eth0 default or whatever, and there are no net eth0 files in /etc/conf.d. I dunno about the files in /etc/init.d/net.ath0 and /etc/init.d/net.eth0 and /etc/init.d/net.lo. Those are pretty long files. But I want to keep the ath0 up.

So, how would I go about doing this?

Thanks in advance.

Have you tried rc-update del net.eth0 ?

/etc/init.d/net.*th0 are init scripts used during boot, you can change them to customize booting.

I did do rc-update del net.eth0. I wrote ath0 in my original post by accident. I want to enable ath0 but disable eth0.

I'm in the I have no /etc/init.d/net.eth0 file, but it's long and I have no idea what all of it means. I just installed this a few days ago.

eth0 will be hotplugged by udev, but there is a way to stop this.

You need to edit /etc/conf.d/rc and look for this:

RC_PLUG_SERVICES=""

and add this in the quotes:

!net.eth0

so that it looks like this:

RC_PLUG_SERVICES="!net.eth0"

You can do that for all of the interfaces that you don't want loaded. That file is very well documented, so please read carefully.

To get net.ath0 back, type this:

rc-update add net.ath0 default
rc-update del net.eth0 default

If you deleted your net.ath0 file in /etc/init.d/, here is the way to get it back:

ln -s /etc/init.d/net.lo /etc/init.d/net.ath0

awsome thanks this one has had me stumped for a little while, tried everything from patches from bugzilla to looking at rewriting the driver. Its always something simple.

You will probably find that this file is a symlink to net.lo try running:

ls -FGg /etc/init.d/net.eth0

It should show something like:

net.eth0 -> net.lo

at the end of the returned line. If this is the case, it is just a symlink to the net.lo file and can be deleted. If it needs to be recreated, then you can do so with:

ln -s net.lo net.eth0
