I have a wireless card called eth1 and a wired nic called eth0. When either eth1 or eth1 and eth0 are managed by ifplugd the names are swapped and settings for wireless setup are applied to eth0 and vice versa. This only happens on startup. An rmmod/modprobe of the wireless card causes the link establishment on just the wireless card. net: # /etc/conf.d/net: # $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/conf.d/net,v 1.7 2002/11/18 19:39:22 azarah Exp $ RC_VERBOSE=yes config_eth0=( "dhcp" ) dhcpcd_eth0="-DN -h Hannah" gateway="eth1/192.168.1.1" modules_eth1=( "iwconfig" ) config_eth1=( "dhcp" ) dhcpcd_eth1="-DN -h Hannah" wireless: # /etc/conf.d/wireless: essid_eth1="shilohap" mode_eth1="managed" channel_eth1="11" sleep_scan_eth1="5" sleep_associate_eth1="5" key_shilohap="s:xxx enc xxx" preferred_aps_eth1=( "shilohap" ) ifplugd -*-sh-*- # $Id: gentoo-ifplugd-conf-v3,v 1.2 2005/03/22 13:05:53 ka0ttic Exp $ INTERFACES="eth0 eth1" AUTO="no" BEEP="yes" IGNORE_FAIL="yes" IGNORE_FAIL_POSITIVE="no" IGNORE_RETVAL="yes" POLL_TIME="1" DELAY_UP="0" DELAY_DOWN="0" API_MODE="auto" SHUTDOWN="no" WAIT_ON_FORK="no" MONITOR="no" ARGS="-f -u 5" MONITOR_eth1="yes" DELAY_UP_eth1="5" DELAY_DOWN_eth1="5" system log: ul 5 10:05:24 [login(pam_unix)] session opened for user root by (uid=0) Jul 5 10:05:54 [ifplugd(eth0)] ifplugd 0.28 initializing.

The interface name is decided by the kernel. As both want "eth", the first one loaded gets "eth0", the second one "eth1". You can alias this in /etc/modules.*d/ all you want, but the behaviour will not change. However, you can write udev rules to fix this or use ifrename (part of wireless-tools - see it's man page) or use the new rename feature in baselayout-1.12.0_pre1-r1.
Thanks Roy for the response. I am not sure that it helps though. I think there is a misunderstanding. In this case the kernel starts the broadcom driver for the wired nic as a builtin module early. So the wired nic gets eth0. It later loads modules according to the modules setup which include the ipw2200 and related modules so it gets eth1. Following this naming by the kernel I then set up the network config to match. This all works if I use the init.d scripts net.eth0 and net.eth1. In fact my workaround is to not use ifplugd and just include the net.eth1 init script in rc-update. However as soon as I use ifplugd it attempts to start the broadcom card as wireless and vice versa. I have not made any attempt to change the references (eth0, eth1) assigned by the kernel. Are you suggesting there is something in the ifplugd config that I have got wrong that is referring to the wrong references? Or are you suggesting that the kernel will randomly change order of loading and so names? If the latter how do you ensure that the configs match the physical cards?
Might I suggest using ifplugd on eth0 only then? You'll be able to use wpa_supplicant-0.4.x and baselayout-1.12.0_pre1 to do the same thing with your ipw card. BTW, I really cannot see anything wrong with your debug log
The original bug is caused by module load order, something with ifplugd does not do
