[gentoo-user] ifplugd and netplug annoyance

[Mike Williams]

Hey,

I installed ifplug a *long* time ago on this laptop, and it worked perfectly.
After upgrading to the new baselayout I saw it had built in support for ifplug 
and netplug.
Great I thought, I'll let it handle it. So I reinstalled ifplug to put all the 
config back to default, and update it.
Now it doesn't work very well.
Well, it works, dhcpcd is stopped when the cable is unplugged, and started 
again when it's plugged back in. But the interface is never actually brought 
down, and that's my problem, I *want* the interface brought *down*.

Why? IPv6. If the interface isn't brought up, stateless autoconfiguration 
doesn't work.

For all my fiddling with ifplugd and netplug, I can't get either to work how 
ifplugd used to.
I've tried using ifplugd as both a deamon with modules=( "!plug" ), and 
letting baselayout handle it fully.
I've messed about with the API ifplugd uses.
Nothing.

Does anyone know how I can get it to work properly?
Ta

Oh, and it would be nice if it could pause the interface, rather than stop it, 
but that's easily hacked in.

Sorry i have neevr used ifplug, but i did have very good luck with
NetworkManager from Gentopia, https://gentopia.gentooexperimental.org/ iknow
it brings the interfaces down like you wanted.

In /etc/conf.d/net, make a postdown that does "ifconfig ${IFACE}
down".  See /etc/conf.d/net.example.

I suspect the reason is that for many adapters (like mine), ifplugd
cannot detect the link state if the interface is completely down, so
plugging in another cable would have no effect.

in /etc/conf.d/ifplugd:
AUTO="yes"

man ifplugd for more details.

The latest baselayout ebuild tells you to remove this file. baselayout
runs ifplugd now, it shouldn't be run separately. As Richard said,
use /etc/conf.d/net for this.

Hmm.  Just re-read /etc/conf.d/net.example and there's a bunch of stuff 
here I never noticed - and I've had baselayout-1.12* ever since it 
entered ~x86, too.  I guess it's time to read the Changelog(s) a bit 
more closely.  Although I knew that ifplugd shouldn't be run on its own 
any more, I had assumed (famous last words, right? ;)) that it still 
used /etc/conf.d/ifplugd.

That message about removing /etc/{init,conf}.d/ifplugd only appeared when
I updated to the most recent baselayout yesterday.

Well, that should be fun.

I've got it working "properly" now (I have an e100 nic, which does properly 
support reading link status when operationally down).
I had to remove /lib/rcscripts/net/ifplugd.sh as I could not disable it from 
conf.d/net
I still have this at the top of conf.d/net:
modules=( "!plug" )
modules_eth0=( "!plug" )
modules=( "!ifplugd" )
modules_eth0=( "!ifplugd" )

The postdown function doesn't get executed with ifplugd.sh in place, as the 
interface is never actually brought down.
