ifplugd.conf - ifplugd configuration file SYNOPSIS
/etc/default/ifplugd DESCRIPTION
ifplugd.conf is the configuration file for ifplugd. It is a shell script that is sourced by the init script starting the daemon. It shall be used to set environment variables which are interpreted by the init script: OPTIONS
INTERFACES Specifies the ethernet interfaces to monitor. It has to contain a space seperated list of network interfaces names. Most users will probably use "eth0" here, however you may add additional interfaces for monitoring more than one device. A special value is sup- ported as well: "auto" will enable a more or less working auto detection of available network devices. This won't make you happy when using network module auto loading, since it cannot detect currently unloaded network devices. HOTPLUG_INTERFACES Specifies the interfaces that can be hotplugged (like interfaces on PCMCIA, USB or WLAN adapters). "all" can be used to make the udev script start an ifplugd process for any hotplugged interfaces (except those already listed in INTERFACES). ARGS Additional command line arguments for ifplugd invocation. See ifplugd(8) for further information. ARGS_iface If specified for an interface this variable takes precedence over ARGS. This may be useful if more than one network device is present. SEE ALSO

ifplugd - A link detection daemon for ethernet devices SYNOPSIS
ifplugd [options] DESCRIPTION
ifplugd is a 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 on-board network adapters, since it will only configure the interface when a cable is really connected. It uses your distribution's native ifup/ifdown programs, but can be configured to do anything you wish when the state of the interface changes. It may ignore short unplugged whiles (-d option) or plugged whiles (-u option). ifplugd may be used in "compatibility mode" by specifying -F on the command line. Than ifplugd will treat network drivers which do not sup- port link beat querying as always online. OPTIONS
-a | --no-auto Do not enable interface automatically (default: off) -n | --no-daemon Do not daemonize (for debugging) (default: off) -s | --no-syslog Do not use syslog, use stdout instead (for debugging) (default: off). -b | --no-beep Do not beep (off), overrides --no-beep-up and --no-beep-down. -U | --no-beep-up Do not beep on interface up (off) -D | --no-beep-down Do not beep on interface down (off) -f | --ignore-fail Ignore detection failure, retry instead. Failure is treated as "no link". (default: off) -F | --ignore-fail-positive Ignore detection failure, retry instead. Failure is treated as "link detected". (default: off) -i | --iface= IFACE Specify ethernet interface (default: eth0) -r | --run= EXEC Specify program to execute when link status changes (default: /etc/ifplugd/ifplugd.action) -I | --ignore-retval Don't exit on nonzero return value of program executed on link change. (default: off) -t | --poll-time= SECS Specify poll time in seconds (default: 1) -T | --poll-utime= USECS Specify poll time in microseconds, added to -t (default: 0) -u | --delay-up= SECS Specify delay for configuring interface (default: 0) -d | --delay-down= SECS Specify delay for deconfiguring interface (default: 5) -m | --api-mode= MODE Force a specific link beat detection ioctl() API. Possible values are auto, iff, wlan, ethtool, mii, and priv for automatic detec- tion, interface flag (IFF_RUNNING), wireless extension, SIOCETHTOOL, SIOCGMIIREG resp. SIOCPRIV. Only the first character of the argument is relevant, case insensitive. (default: auto) -p | --no-startup Don't call the script to bring up network on deamon start (default: off) -q | --no-shutdown Don't call the script for network shutdown on deamon quit (default: off) -w | --wait-on-fork When daemonizing, wait until the background process finished with the initial link beat detection. When this is enabled, the parent process will return the link status on exit. 2 means link beat detected, 3 stands for link beat not detected, everything else is an error. -W | --wait-on-kill When killing a running daemon (with -k) wait until the daemon died. -x | --extra-arg= ARG Specify an extra argument to be passed to the action script. -M | --monitor Don't fail when the network interface is not available, instead use NETLINK to monitor device avaibility. The is useful for PCMCIA devices and similar. -h | --help Show help -k | --kill Kill a running daemon (Specify -i to select the daemon instance to kill) -c | --check-running Check if a daemon is running for a given network interface. Sets the return value to 0 if a daemon is already running or to 255 if not. -v | --version Show version -S | --supend Suspend a running daemon. The daemon will no longer check the link status until it is resumed (-R) again. (Specify -i to select the daemon instance to suspend.) -R | --resume Resume a suspended daemon. (Specify -i to select the daemon instance to resume.) -z | --info Request that a running daemon shall write its status information to syslog. (Specify -i to select the daemon instance to send the request to.) FILES
/etc/default/ifplugd: this file is sourced by the init script /etc/init.d/ifplugd and contains the interface to be monitored and the options to be used. /etc/ifplugd/ifplugd.action: this is the script which will be called by the daemon whenever the state of the interface changes. It takes two areguments: the first is the interface name (eg. eth0), the second either "up" or "down". /var/run/ifplugd.<iface>.pid: the pid file for ifplugd. ENVIRONMENT
The action script will be called with two environment variables set: IFPLUGD_PREVIOUS The previous link status. Either "up", "down", "error" or "disabled". The former values should be obvious, the latter is set on daemon startup. IFPLUGD_CURRENT The current link status. See above for possible values. SIGNALS
SIGINT, SIGTERM ifplugd will quit, possibly running the shutdown script. This is issued by passing -k to ifplugd. SIGQUIT ifplugd will quit, the shutdown script is never run. SIGHUP ifplugd will write its status information to syslog. This is issued by -z. SIGUSR1 ifplugd will go to suspend mode. (-S) SIGUSR2 ifplugd will resume from suspend mode. (-R) AUTHOR
