ifplugd 0.27

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.
Installation:
As this package is made with the GNU autotools you should run ./configure inside the distribution directory for configuring the source tree. After that you should run make for compilation and make install (as root) for installation of ifplugd.
The installation scripts create an init script in ${sysconfdir}/init.d/ifplugd, however no /etc/rc?.d/ links are created for it.
This is useful on laptops with onboard network adapters, since it will only configure the interface when a cable is really connected.
Main features:
- Uses your distributions native ifup/ifdown programs.
- May beep when the cable is unplugged, plugged, the interface configuration succeeded or failed.
- Supports the Linux SIOCETHTOOL (newer, aka ethtool API), SIOCGMIIREG (older, aka mii-diag/mii-tool API) and SIOCDEVPRIVATE (oldest, aka mii-tool API) ioctl()s for getting link status. Release 0.24 introduces support for link detection with the IFF_RUNNING interface flag.
- Syslog support
- Small program - the binary is just 25 KB (plus 16 KB for libdaemon).
- Multiple ethernet interface support
- Can be configured to ignore short "unplugged" periods (-d option) or short "plugged" periods(-u option)
- Support for wireless networking. Whenever an association to an AP is detected the network is configured. Have a look on waproamd if you need a facility to configure WEP keys before AP associations succeed.
- Compatibility mode for network devices which do not support cable detection (-F option)
