Migration of wpa_supplicant Based on fs2410

The previous article has successfully transplanted sdio WiFi, but the AP is not encrypted. Currently, most wireless wi-fi networks are encrypted by WPA. Therefore, wpa_supplicant is required. The following is the migration process:

1. Download source code
Http://hostap.epitest.fi/wpa_supplicant/
Download wpa_supplicant-0.7.3.tar.gz (OpenSSL uses the 0.7.3 patch)
# Tar xvfz wpa_supplicant-0.7.3.tar.gz
Download www.openssl.org/source/openssl-0.9.8e.tar.gz
# Tar zxvf openssl-0.9.8e.tar.gz

Ii. Compile the OpenSSL library
Copy the patch from wpa_supplicant to OpenSSL.
# Cp wpa_supplicant-0.7.3/patches/openssl-0.9.8e-tls-extensions.patch openssl-0.9.8e/
# Cd openssl-0.9.8e
# Mkdir/usr/local/SSL
# Vim makefile
CC= Arm-Linux-GNU-gcc
Ar= Arm-Linux-GNU-ar $ (arflags) r
Ranlib= Arm-Linux-GNU-ranlib
Installtop=/Usr/local/SSL
Openssldir=/Usr/local/SSL
# Make
# Make install

Install the SSL library in the/usr/local/SSL directory
# Ls/usr/local/SSL
#Bin certs include lib man MISC OpenSSL. CNF private

Wpa_supplicant will be compiled later to depend on lib and include in OpenSSL.

3. Compile wpa_supplicant
Into the wpa_supplicant-0.7.3.tar.gz unzip the generated wpa_supplicant-0.7.3/wpa_supplicant directory:
# Cp defconfig. config
# Vim. config
Cc = arm-Linux-GNU-gcc-L/usr/local/SSL/lib/
Cflags + =-I/usr/local/SSL/include/
Libs + =-L/usr/local/SSL/lib/
# Make

The compiled wpa_supplicant source code shows two main executable tools: wpa_supplicant and wpa_cli. Wpa_supplicant is the core program, and its relationship with wpa_cli is the relationship between the service and the client: wpa_supplicant is run in the background, and wpa_cli is used to search, set, and connect to the network.

4. Configure wpa_supplicant
(1) first copy wpa_supplicant and wpa-psk-tkip.conf to the development board root file system, and renamedWpa-psk-tkip.confIsWpa_supplicant.conf

#CP wpa_supplicant/rootfs/filesystem/bin
#CP wpa_supplicant-0.7.3/wpa_supplicant/examples/wpa-psk-tkip.conf/rootfs/filesystem/etc/wpa_supplicant.conf

(2) modify the wpa_supplicant.conf configuration file
# Vim/rootfs/filesystem/etc/wpa_supplicant.conf

The modification content is as follows:

# WPA-PSK/TKIP

Ctrl_interface =/var/run/wpa_supplicant

Network = {
SSID ="Fs2410"// Enter the wireless network user name
Key_mgmt = WPA-PSK
PROTO = WPA
Pairwise = TKIP
Group = TKIP
PSK ="1234567890"// Enter the password
}

V. Test
(1) On the Development Board terminal:

#Mkdir-P/var/run/wpa_supplicant

(2) Compile the driver loading script
# Vim load. Sh (I put it in the root file system/sdio directory, the content is as follows :)

#! /Bin/sh CD/sdio Insmod libertas. Ko Insmod libertas_sdio.ko helper_name =/lib/firmware/mrvl/helper_sd.bin fw_name =/lib/firmware/mrvl/sd8686.bin

And modify the load. Sh permission:Chmod 777 load. Sh

(3) load the driver
Enter the/sdio directory on the Development Board terminal and run./load. Sh to load the driver.
#CD/sdio
#./Load. Sh
After the driver is loaded, the following message is displayed: (if not, you can hot your sdio WiFi card again)
Libertas_sdio: libertas sdio driver
Libertas_sdio: Copyright Pierre Ossman
Libertas: 00: 0b: 6C: 89: 62: 4B, FW 9.70.3p23, Cap 0x00000303
Libertas: unidentified region code; using the default (USA)
Libertas: wlan0: Marvell WLAN 802.11 Adapter

Ifconfig-a to check whether the wlan0 node is created.
Assign IP Address:
#Ifconfig wlan0 192.168.1.5// You can also dynamically allocate dhclient wlan0, but you have to port DHCP.

(4) create a connection password (PSK password) and use the plaintext to convert the password.
# Cd/etc
#Wpa_passphrase fs2410 1234567890> wpa_supplicant.conf
This will be generated in the wpa_supplicant.conf file:
Network = {
SSID = "fs2410"
# PSK = "1234567890"
PSK = Signature
}

(5) then modify the wpa_supplicant.conf configuration file and change the line PSK = "1234567890" to the generated password in plaintext, that is:
PSK = Signature
Delete other generated redundant information. The wpa_supplicant.conf file is as follows:

# WPA-PSK/TKIP Ctrl_interface =/var/run/wpa_supplicant Network = { SSID = "fs2410" // enter the User Name of the wireless network Key_mgmt = WPA-PSK PROTO = WPA Pairwise = TKIP Group = TKIP PSK = Signature }

(6) connect to the AP
Enter on the development board TerminalWpa_supplicantPress enter to display the help information. The last one is:
Example:
Wpa_supplicant-dwext-iwlan0-C/etc/wpa_supplicant.conf
Copy example usage and execute:
# Wpa_supplicant-dwext-iwlan0-C/etc/wpa_supplicant.conf&(You need to keep running in the background)
The printed information includes:

Ping the gateway again to check whether the connection is successful:
