Installing wpa_supplicant
AtRPMS contains packages for Fedora Core.
- Get the source
- Make sure your kernel includes the drivers for your wireless card. Here's a sample .config for madwifi users:
# #.config # # Uncomment following two lines and fix the paths if you have installed openssl # in non-default location #CFLAGS += -I/usr/local/openssl/include #LIBS += -L/usr/local/openssl/lib # Driver interface for Host AP driver #CONFIG_DRIVER_HOSTAP=y # Driver interface for Agere driver #CONFIG_DRIVER_HERMES=y # Change include directories to match with the local setup #CFLAGS += -I../../hcf -I../../include -I../../include/hcf #CFLAGS += -I../../include/wireless # Driver interface for Prism54 driver # (Note: Prism54 is not yet supported, i.e., this will not work as-is and is # for developers only) #CONFIG_DRIVER_PRISM54=y # Driver interface for ndiswrapper #CONFIG_DRIVER_NDISWRAPPER=y # Driver interface for Atmel driver #CONFIG_DRIVER_ATMEL=y # Driver interface for Broadcom driver #CONFIG_DRIVER_BROADCOM=y # Example path for wlioctl.h; change to match your configuration #CFLAGS += -I/opt/WRT54GS/release/src/include # Driver interface for Intel ipw2100/2200 driver #CONFIG_DRIVER_IPW=y CONFIG_DRIVER_MADWIFI=y # Change include directories to match with the local setup CFLAGS += -I../madwif CONFIG_DRIVER_WEXT=y # Driver interface for FreeBSD net80211 layer (e.g., Atheros driver) #CONFIG_DRIVER_BSD=y #CFLAGS += -I/usr/local/include #LIBS += -L/usr/local/lib # Driver interface for Windows NDIS #CONFIG_DRIVER_NDIS=y #CFLAGS += -I/usr/include/w32api/ddk #LIBS += -L/usr/local/lib # For native build using mingw #CONFIG_NATIVE_WINDOWS=y # Additional directories for cross-compilation on Linux host for mingw target #CFLAGS += -I/opt/mingw/mingw32/include/ddk #LIBS += -L/opt/mingw/mingw32/lib #CC=mingw32-gcc # Driver interface for development testing #CONFIG_DRIVER_TEST=y # Driver interface for wired Ethernet drivers #CONFIG_DRIVER_WIRED=y CONFIG_IEEE8021X_EAPOL=y # EAP-MD5 (automatically included if EAP-TTLS is enabled) CONFIG_EAP_MD5=y # EAP-MSCHAPv2 (automatically included if EAP-PEAP is enabled) CONFIG_EAP_MSCHAPV2=y # EAP-TLS CONFIG_EAP_TLS=y # EAL-PEAP CONFIG_EAP_PEAP=y # EAP-TTLS CONFIG_EAP_TTLS=y # EAP-GTC CONFIG_EAP_GTC=y # EAP-OTP CONFIG_EAP_OTP=y # LEAP CONFIG_EAP_LEAP=y # PKCS#12 (PFX) support (used to read private key and certificate file from # a file that usually has extension .p12 or .pfx) CONFIG_PKCS12=y # Include control interface for external programs, e.g, wpa_cli CONFIG_CTRL_IFACE=y
- install wpa_supplicant by
# make && make install
Configuration
Set wpa_supplicant.conf to the following:
You have to change the values according to the response of # wpa_passphrase <yourAPssid> <yourpassphrase>
.
For WPA-PSK
ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=0 eapol_version=1 # ap_scan=2 was the one for me you may try 0 or 1 indstead of 2 ap_scan=2 fast_reauth=1 network={ ssid="my_network" proto=WPA key_mgmt=WPA-PSK pairwise=TKIP group=TKIP psk="secret_password" }
For WPA2-Personal
ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=0 ap_scan=1 network={ ssid="my_network" proto=RSN key_mgmt=WPA-PSK pairwise=CCMP TKIP group=CCMP TKIP psk="secret_password" }
Starting wpa_supplicant
When using a recent ipw2200 driver
When using a recent ipw2200 driver (e.g., as found in recent mainline kernels):
# wpa_supplicant -d -c/etc/wpa_supplicant.conf -ieth1 -Dwext
If every thing works as expected, you can replace -d by -B for the deamon mode.
In the instructions below, replace the interface name ath0 with the appropriate one (usually eth1).
When using the madwifi driver
Make sure that the modules ath_pci, ath_hal, ath_rate_sample, wlan, wlan_tkip and wlan_xauth are loaded (using # lsmod
).
Now you are able to start wpa_supplicant by
# wpa_supplicant -d -c /etc/wpa_supplicant.conf -iath0 -Dmadwifi
If every thing works as expected, you can replace -d by -B for the deamon mode.
Bringing up the network card manually
- Bring up the network interface with
# ifconfig ath0 <yourip> up
.
There are two patches one for wpa_supllicant (http://hostap.epitest.fi/bugz/show_bug.cgi?id=63) and one for madwifi
(http://article.gmane.org/gmane.linux.drivers.madwifi.devel/1275). Each one is supposed to work.- Change the routes and add the default gateway.
Bringing up the device at boottime (for Gentoo users)
- Make a symbolic link
# cd /etc/init.d/
# ln -s net.lo net.ath0
- Copy wpa_supplicant.conf to /etc/conf.d/wpa_supplicant.
- Edit /etc/conf.d/net
# #net # modules=( "wpa_supplicant" ) wpa_supplicant_ath0="-Dmadwifi"modules=( "wpa_supplicant" ) wpa_timeout_ath0=60 config_ath0=("<yourip> netmask 255.255.255.0") routes_ath0=("default gw <yourgateway>")
- Add net.ath0 to the default runlevel by executing
# rc-update add net.ath0 default
- Make sure all needed modules are in /etc/modules.autoload/2.x
