NAME
       ifplugstatus - A link beat detection tool

SYNOPSIS
       ifplugstatus [options] [INTERFACE]

DESCRIPTION
       ifplugstatus  is an utility which may be used to detect the link status
       of a local Linux ethernet device, much in the same way  mii-diag,  mii-
       tool  and  ethtool  work.  In fact it supports all three different APIs
       these three tools use. In addition it supports link checking  with  the
       IFF_RUNNING  interface flag, which most modern drivers (not only ether‐
       net) support, and association status checking with the wireless	exten‐
       sion API for WLAN devices.

       The APIs are tried in the following order:

       First the newest API: SIOCETHTOOL (aka ethtool API)

       Second the next older API: SIOCGMIIREG (aka mii-diag API)

       Than the WLAN API: wireless extension (aka iwconfig API)

       Followed by the cleanest API: IFF_RUNNING (aka ifconfig API)

       The  oldest  API	 (SIOCPRIV aka mii-tool API) is not tested since it is
       obsolete.

       ifplugstatus may be used in shell script since it returns  the  current
       status as return value. It is especially useful to detect the available
       APIs on the used network driver. (Option -v)

OPTIONS
       You may specify an ethernet  device  on	the  command  line.  Otherwise
       ifplugstatus will check all available network interfaces.

       -a | --auto
	      Enable interface automatically before querying (default: off)

       -h | --help
	      Show help

       -q | --quiet
	      Decrease verbosity by one. If the verbosity is < 0, no text will
	      be shown, only the return value is relevant; if the verbosity is
	      =	 0,  a	terse  status  will be shown; If the verbosity is > 0,
	      detailed information about the used API is returned. (By default
	      the verbosity is 0)

       -v | --verbose
	      Increase verbosity by one. See option -q.

       -V | --version
	      Show version

RETURN VALUES
       0 Success

       1 Failure

       2 Link beat detected (only available when an interface is specified)

       3 Unplugged (same here)
