News

+ +
Mon July 7 2003:

Version +0.14 released, changes include: autoconf usage, new dependency libdaemon, wireless LAN support, support for +suspending/resuming, many fixes

+ +

Overview

+ +

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.

+ +

ifplugd ifplugd interfaces with your distribution's native network + configuration utilities.

+ +

Some features:

+ + + +

Status

+ +

Version @PACKAGE_VERSION@ is stable and has all the sensible features its users could think of.

+ +

Documentation

+ +

Have a look on the man pages ifplugd(8), ifplugstatus(8), ifplugd.conf(5). (An XSLT capable browser is required)

+ +

Configuration

+ +

Edit /etc/ifplugd/ifplugd.conf for configuration +changes. This file is a bourne shell script sourced by the init script +and used to start ifplugd with appropriate arguments. You may specify more than +one ethernet interface in INTERFACES. For each interface a +seperate instance of ifplugd is spawned. The arguments specified in +ARGS are append to ifplugd's command line. Have a look on +ifplugd -h or man ifplugd for further information +about the available options.

+ +

The network interface which is controlled by ifplugd +should not be configured automatically by your distribution's network +subsystem, since ifplugd will do this for you if needed.

+ +

On Debian systems, any interfaces named in ifplugd's +INTERFACES environment variable should not also be listed in +an "auto" stanza in /etc/network/interfaces.

+ +

Troubleshooting

+ +

When you are using the hotplug subsystem (Debian package +hotplug) you may notice that the network device is configured +even when it is not listed on an auto line in +/etc/network/interface. This may be due to hotplug +being configured to ifup the network interface when it +becomes available. This was the default behavior in the Debian +hotplug package prior to release 0.0.20030117-1, for +example. To prevent this you should either upgrade your +hotplug package or comment out the ifup call in +/etc/hotplug/net.agent.

+ +

When using ifplugd together with APM (and probably ACPI) +suspends, strange things may happen: some network devices fail to +detect the network cable for a short period of time before and after +the suspend. When using the -f switch, this will be treated +as "no link beat", thus the network is shutdown after a +timeout. During this timeout the machine changes to suspended +state. When it is resumed again, the timeout period will have expired +and so the network is deconfigured, however, as the next cable +detection succeeds, the network is configured again immediately. To +fix this problem, ifplugd should be disabled before the APM +suspend and enabled back after the suspend. This may be done by using +apmd and adding a script to +/etc/apm/{suspend,resume}.d which simply calls +/etc/init.d/ifplugd suspend, resp. /etc/init.d/ifplugd +resume. It might even be a good idea to shut down the network +completely during suspend, this may be achieved by calling +/etc/init.d/ifplugd stop and /etc/init.d/ifplugd +start in the appropriate places. I strongly urge the packagers of +this software for the Linux distributions to add such scripts to their +packages.

+ +

FAQ

+ +
    +
  1. Q: I want to use ifplugd with my PCMCIA device, but ifplugd quits + when it doesn't find eth0, when I have not inserted the + card. What can I do?

    + +

    A: Use the -f switch. This is not very clean however, + since modprobe is called on each cable detection query of ifplugd to + load a module for the network device. This is suboptimal. You should + probably run ifplugd only when the card is really inserted.

    +
  2. + +
  3. Q: I am using the -f switch, but the kernel logs are getting filled + with messages like "modprobe: modprobe: Can't locate module + eth0". What can I do?

    + +

    A: Make sure you have a line like alias eth0 off in your /etc/modules.conf

    +
  4. + +
  5. Q: When the cable is unplugged and the interface shut down it is + still available with ifconfig and markes as UP. Why this?

    + +

    A: ifplugd cannot detect the link beat with a shut down interface on + certain (most as of kernel 2.4.19) network drivers. Thus ifplugd + enables the interface before querying the link status. This may + be switched off with -a flag. You might want to use it if you + have a sane network driver (e.g. eepro100). The subdirectory + patches/ in the ifplugd distribution includes a patch for the + 8139too 0.9.26 driver, which makes the driver compatible with + -a. Don't ask me how to apply this patch. If you don't know, you + won't need it.

  6. + +
  7. Q: Does it work with anything else than plain ethernet or wireless LAN?

    + +

    A: Certainly not, since the MII and +ETHTOOL ioctl()s and the wireless extension don't +exist on + other network device types.

  8. + +
  9. Q: I have a Realtek 8139 based network card. Everytime ifplugd + starts on bootup my machine freezes. What can I do?

    + +

    A: This is a bug in the 8139too driver 0.9.25 (at least) shipped + with Linux 2.4.19, please upgrade to 8139too 0.9.26 (Linux 2.4.20 + or seperately at http://www.sourceforge.net/projects/gkernel/).

  10. + + +
  11. Q: There are already laptop-net's ifd and miid, why did you write + your own daemon?

    + +

    A: laptop-net was too integrated with its profile +system and didn't work on my hardware when I had a look on it. It +seemed easier to me to write a simple but feature complete replacement +than using laptop-net without most of the special features disabled. I +didn't know about miid when I wrote + ifplugd, but in any case ifplugd is much better +than miid. For a + comparison of miid and ifplugd, have a look on + + http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=162763&repeatmerged=yes

+ + +

Requirements

+ +

A newer Linux Kernel (I think 2.2 is good enough, alltough I tested it +only with 2.4) with a compatible device driver and +ethernet card. Most modern cards and drivers are compatible, like mine +which works with the 8139too driver.

+ +

ifplugd was developed and tested on Debian GNU/Linux +"testing" from July 2003, it should work on most other Linux +distributions (and maybe Unix versions) since it uses GNU autoconf and +GNU libtool for source code configuration and shared library +management.

+ +

The machine used was a Medion 9580-F laptop with a Realtek 8139 +network card and a PRISM1 PCMCIA wireless LAN card.

+ +

ifplugd needs libdaemon.

+ +

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.

+ +

Extensive installation instructions for ifplugd are available at Geoff Ericksson's web site.

+ +

Acknowledgements

+ +
