Introduction to ifplugd
ifplugd is a Linux daemon which will automatically configure your ethernet device when a cable is plugged in and automatically unconfigure it if the cable is pulled. This is useful on laptops with onboard network adapters, since it will only configure the interface when a cable is really connected.
With the clfs-bootscripts, you will get an ethernet connection if the cable is connected when you boot, but otherwise will not - even if you connect the cable later. With ifplugd, you will have a connection whenever the cable is connected - regardless of whether it was connected on boot or how many times you unplug and plug it back in after booting.
ifplugd also works with wireless devices. See http://0pointer.de/lennart/projects/ifplugd/ for more details.
Dependencies
Required
Optional
- xmltoman (for rebuilding the man pages)
- Subversion (for rebuilding svn-release.h)
- Lynx (for regenerating the README)
Additional Configuration Options
If you don't have lynx installed, pass the following flag to configure:
--disable-lynx
If you don't have xmltoman installed, pass the following flag to configure:
--disable-xmltoman
If you don't have subversion installed, pass the following flag to configure:
--disable-subversion
Nothing bad happens if you don't have one of the optional packages and you forget to pass the disabling flag, but configure will complain with a warning.
Non-Multilib
Compile the package:
./configure --prefix=/usr --sysconfdir=/etc --sbindir=/sbin make
Install the package:
make install
Remove unnecessary links from the clfs-bootscripts:
rm -v /etc/rc.d/*/K80network rm -v /etc/rc.d/*/S20network
You won't need it, so you can removed the actual network script if you want, but then if you decide you want it, then you'll have to reinstall it from the clfs-bootscripts package.
rm -v /etc/rc.d/init.d/network
Create the links necessary to have ifplugd actually run:
ln -sv ../init.d/ifplugd /etc/rc.d/rc1.d/K80ifplugd ln -sv ../init.d/ifplugd /etc/rc.d/rc2.d/S20ifplugd ln -sv ../init.d/ifplugd /etc/rc.d/rc3.d/S20ifplugd ln -sv ../init.d/ifplugd /etc/rc.d/rc4.d/S20ifplugd ln -sv ../init.d/ifplugd /etc/rc.d/rc5.d/S20ifplugd ln -sv ../init.d/ifplugd /etc/rc.d/rc6.d/K80ifplugd
Alter /etc/ifplugd/ifplugd.action so that it points to the correct location for the ifdown and ifup scripts:
sed -i 's@/sbin/@/etc/sysconfig/network-devices/@g' /etc/ifplugd/ifplugd.action
Command Explanations
--sysconfdir=/etc: We use this flag because the default is /usr/etc which you probably don't want to happen.
--sbindir=/sbin: We use this flag because the default is /usr/sbin and you may want ifplugd to be available even when /usr is on another partition.
rm -v ....: The ifplugd script effectively replaces clfs-bootscripts' network script, so we need to remove the network script (or at least its links in /etc/rc.d/rcX.d) so that they won't try to run.
ln -sv ....: We need to have links in the /etc/rc.d/rcX.d directories in order for ifplugd to run.
sed -i ....: ifplugd.action points to /sbin for the ifdown and ifup scripts, but on clfs systems, they reside in /etc/sysconfig/network-devices, so we need to redirect it.
Multilib
This package does not provide any libraries so only one installation is needed.
32Bit
Compile the package:
./configure PKG_CONFIG_PATH="${PKG_CONFIG_PATH32}" \
CC="gcc ${BUILD32}" --prefix=/usr \
--sysconfdir=/etc --sbindir=/sbin
make
Install the package:
make install
Remove unnecessary links from the clfs-bootscripts:
rm -v /etc/rc.d/*/K80network rm -v /etc/rc.d/*/S20network
You won't need it, so you can removed the actual network script if you want, but then if you decide you want it, then you'll have to reinstall it from the clfs-bootscripts package.

Configuring ifplugd
Configuration File
/etc/ifplugd/ifplugd.conf
Configuration Information
In ifplugd.conf, set INTERFACES to the network interfaces that you have on your computer (e.g. eth0).
Also, if you want to pass ifplugd parameters other than the defaults, you need to set ARGS (also within ifplugd.conf) to the parameters that you actually want. However, the defaults are probably sufficient.
