[gentoo-user] net.eth0 device initiated services

[Mihamina Rakotomandimby]

Hi,
I have /etc/init.d/net.eth0.
I dont want it to be launch at boot, but I dont want to delete it either
because it eases some things when I want to bring eth0 up.

My problem is although i "del" it from the boot process with rc-update,
net.eth0 is attempted to be brought up by some other tool.

When no cable is plugged, it slows as hell the boot process.

The message is "device initiated services: net.eth0".
Then bringing up attempt comes.
who the hell is trying to bring it up?

The answer is here:
http://www.linuxquestions.org/questions/showthread.php?p=2520311

	/etc/conf.d/rc

	- RC_PLUG_SERVICES="" 
	+ RC_PLUG_SERVICES="!net.*"

I tend to set the eth0 dhcpcd timeout at ~5 seconds. The DHCP server I
usually use (the gentoo based server under my desk!) always responds
within 5 seconds. When I'm out and about and using/"borrowing" a
wireless connection it means that it only slows the boot process by 5
seconds and doesnt require me to manually enable or disable eth0.

it might be a nice idea to look into how knoppix backgrounds the dhcp 
process and implement that into Gentoo's init,
i think i did get annoyed with the dhcp process taking ages a few years 
back and just put a '&' at the end of the dhcp line, i cant remember if 
this worked or not tho.

Does this not then delay services depending on net.eth0? Although it
would perhaps make sense to do init scripts in the order:

1) Everything needed to get eth0 up
2) net.eth0
3) Non network reliant stuff
4) Network reliant stuff

If this makes sense ... ;>

Or you could emerge ifplugd, then the startup scripts won't try to
initialise eth0 if no cable is detected.

Ah, never knew that existed. Thanks :)

you can name the kernels in /boot anything, so long as the name is
referenced in /boot/grub/grub.conf correctly.  

you can decrease the boot time by giving your dhcp client a timeout
value in seconds.  I use 10 seconds for my desktops, because if my
dhcpserver isn't responding by then, it's probably broken.

Is there something like this which will bring my wireless connection up
or down depending on whether the device is found?  (My laptop has a
hardware switch to turn the wireless card on/off).

I have a USB WiFi adaptor which is picked up and initialised by ifplugd 
everytime I plug it in.  I assume that the same will happen when you turn 
your wireless card on/off.

I am not sure what happens when I have both an ethernet cable plugged in and 
the WiFi adaptor.  I guess both will come up but which one is going to be 
used by applications to connect to the Internet?

I use the preup() function in /etc/conf.d/net to take my wireless
interface down when the wired interface is brought up.

preup() {
	if [ ${IFACE} == "eth0" ]; then
		/etc/init.d/net.eth1 --quiet status && /etc/init.d/net.eth1 pause fi
	return 0
}
