supplicant commond
Command line options
--------------------
usage:
wpa_supplicant [-BddfhKLqqtuvwW] [-P<pid file>] [-g<global ctrl>] \
-i<ifname> -c<config file> [-C<ctrl>] [-D<driver>] [-p<driver_param>] \
[-b<br_ifname> [-N -i<ifname> -c<conf> [-C<ctrl>] [-D<driver>] \
[-p<driver_param>] [-b<br_ifname>] ...]
options:
-b = optional bridge interface name
-B = run daemon in the background
-c = Configuration file
-C = ctrl_interface parameter (only used if -c is not)
-i = interface name
-d = increase debugging verbosity (-dd even more)
-D = driver name
-f = Log output to default log location (normally /tmp)
-g = global ctrl_interface
-K = include keys (passwords, etc.) in debug output
-t = include timestamp in debug messages
-h = show this help text
-L = show license (GPL and BSD)
-p = driver parameters
-P = PID file
-q = decrease debugging verbosity (-qq even less)
-v = show version
-w = wait for interface to be added, if needed
-W = wait for a control interface monitor before starting
-N = start describing new interface
drivers:
hostap = Host AP driver (Intersil Prism2/2.5/3) [default]
(this can also be used with Linuxant DriverLoader)
hermes = Agere Systems Inc. driver (Hermes-I/Hermes-II)
madwifi = MADWIFI 802.11 support (Atheros, etc.)
atmel = ATMEL AT76C5XXx (USB, PCMCIA)
wext = Linux wireless extensions (generic)
ndiswrapper = Linux ndiswrapper
broadcom = Broadcom wl.o driver
ipw = Intel ipw2100/2200 driver (old; use wext with Linux 2.6.13 or newer)
wired = wpa_supplicant wired Ethernet driver
bsd = BSD 802.11 support (Atheros, etc.)
ndis = Windows NDIS driver
In most common cases, wpa_supplicant is started with
wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -iwlan0
This makes the process fork into background and wait for the wlan0
interface if it is not available at startup time.
The easiest way to debug problems, and to get debug log for bug
reports, is to start wpa_supplicant on foreground with debugging
enabled:
wpa_supplicant -c/etc/wpa_supplicant.conf -iwlan0 -d
wpa_supplicant can control multiple interfaces (radios) either by
running one process for each interface separately or by running just
one process and list of options at command line. Each interface is
separated with -N argument. As an example, following command would
start wpa_supplicant for two interfaces:
wpa_supplicant \
-c wpa1.conf -i wlan0 -D hostap -N \
-c wpa2.conf -i ath0 -D madwifi
If the interface is added in a Linux bridge (e.g., br0), the bridge
interface needs to be configured to wpa_supplicant in addition to the
main interface:
wpa_supplicant -cw.conf -Dmadwifi -iath0 -bbr0
