Hi

i have some troubles with gentoo on my laptop. so i have removed the eth0 link in default runlevel because i am not always connected. the problem is that the init script for eth0 start at every boot and i don't know why.

here my runlevels:
Code:
thor(11:58:43) /home/thomas # ll /etc/runlevels/*

it seems to be that another script need eth0

eth0 start just after net.lo and before urandom

thanks

It's udev that starts eth0. If you want to use a nice solution emerge netplug, it will sense if you have a cable plugged in or not and start eth0 when you need it.

i dont think so :
Code:
thor(13:10:39) /home/thomas # /etc/init.d/net.eth0 stop
 * Service net.eth0 stopping
 * Service net.eth0 stopped
thor(13:11:08) /home/thomas # /etc/init.d/net.lo restart
 * Service net.lo stopping
 * WARNING:  you are stopping a boot service.
 * Service net.lo stopped
 * Service net.lo starting
 * Service net.lo started


i will reboot to try netplug

it's working : the system don't stay stuck 15seconds when the cable is not plugged :

after have started the laptop without the eth cable:
Code:
thor(13:21:56) /home/thomas # rc-status ac_adapter
Runlevel: ac_adapter
 acpid                                                              [ started  ]
 alsasound                                                          [ started  ]
 hald                                                               [ stopped  ]
 iptables                                                           [ started  ]
 local                                                              [ started  ]
 net.eth0                                                           [ inactive ]
 netmount                                                           [ stopped  ]
 ntpd                                                               [ stopped  ]
 portmap                                                            [ stopped  ]
 xdm                                                                [ started  ]

then i plug the cable:
Code:

thor(13:22:06) /home/thomas # rc-status ac_adapter
Runlevel: ac_adapter
 acpid                                                              [ started  ]
 alsasound                                                          [ started  ]
 hald                                                               [ stopped  ]
 iptables                                                           [ started  ]
 local                                                              [ started  ]
 net.eth0                                                           [ started  ]
 netmount                                                           [ stopped  ]
 ntpd                                                               [ stopped  ]
 portmap                                                            [ stopped  ]
 xdm                                                                [ started  ]


i am in default runlevel, i have shown the ac_adapter status to see the net.eth0 script.

Thanks a lot Ehnvis and Gerard van Vuuren !

Can you post your /etc/conf.d/rc, because I had that problem with eth0 and I add this in this file :

Code:

RC_PLUG_SERVICES="!net.*"

As d2_racing mentioned, it is started via the rc plug service, so it is unrelated to runlevels (unless you add it to some runlevel on purpose). What I suggest is to emerge netplug and let it background the connection until an ethernet cable is plugged into the machine.

ifplugd is older and, I think, not supported anymore. I've had better experiences with netplug.

Does netplug is simple as ifplugd, because I only emerge ifplugd and I didn't changed anything.

Everything runs out of the box.

Yep, netplug is supported by the baselayout, so all you need to do is emerge it, and it will be automatically be backgrounded when net.eth* is started. You can have it work for other net.* devices as well.

I'm not sure what happens if you have both ifplud and netplug installed at the same time, but I would recommend using one or the other.

/etc/conf.d/rc is a nice feature I can agree on that, but on the other hand if your lazy like me netplug and ifplugd is 2 nice tools.
And having to start net.ethX each time you plug in the cable (if you move between locations alot) it will just irritate you (atleast I
get irritated by that).
