getting WPA to work

[ripper]

*****EDIT ... THIS DOES NOT WORK IN OS REVISION B *********

type the following into a console:

Code: Select all

sudo -s
ifconfig ra0 down
ifconfig ra0 up
iwconfig ra0 essid “ESSID_IN_QUOTES”
iwpriv ra0 set AuthMode=WPAPSK
iwpriv ra0 set EncrypType=TKIP
iwpriv ra0 set WPAPSK=”YOUR_WPA_PSK_KEY”
dhcpcd ra0

to get your WPA PSK KEY for the above command

Code: Select all

wpa_passphrase YOUR_ESSID

after you run the above it will prompt you to type in your password for the WPA

This is a quick fix untill they add WPA to thier network GUI. I will write up a little script later today and post it here for people to use. But all and all, WPA is working fine for me.

Thanks. I know this is beta software, but I'm a little surprised that it's *this* beta. Your solution worked. Too bad it has to be done every single time the computer is restarted. But I've already received an email from AI stating that they intend to have a new image up shortly. My expectation is that it is designed to address this issue. At least, I certainly HOPE it will permanently address this issue.

Here is the dirty little script I have been using for WPA. To use it create a file named WPA_wifi.sh

Code: Select all

touch WPA_wifi.sh

Change the permissions

Code: Select all

chmod 755 WPA_wifi.sh

open wifi.sh with your favorite editor

Code: Select all

vi WPA_wifi.sh

cut and paste the following code into the file and save

Code: Select all

#!/bin/sh                                                                       
if [ $1 == "start" ]                                                           
then                                                                           
        psk=`echo $3 | wpa_passphrase $2 |grep '\spsk='|cut -b 6-69`           
        rmmod rt3070sta                                                         
        modprobe rt3070sta                                                     
        ifconfig ra0 up                                                         
        iwconfig ra0 essid $2                                                   
        iwpriv ra0 set AuthMode=WPAPSK                                         
        iwpriv ra0 set EncrypType=TKIP                                         
        iwpriv ra0 set WPAPSK=$psk                                             
        dhcpcd ra0                                                             
elif [ $1 == "stop" ]                                                           
then                                                                           
        killall dhcpcd                                                         
else                                                                           
        echo "USEAGE FOR WPA_WIFI.SH"                                           
        echo "#### To start your connection: ####"                             
        echo "./WPA_wifi.sh start YOUR_AP_NAME YOUR_AP_PASSWORD"               
        echo "#### To stop your connection: ####"                               
        echo "./WPA_wifi.sh stop"                                               
fi                         


to use it change to root

Code: Select all

sudo -s

then run it with your access points name and your WPA password in plane text

Code: Select all

./WPA_wifi.sh start AP_NAME WPA_PASSWORD

There is still a problem with the shutdown command of this script. So you must restart your computer to connect to a new access point at the moment. If I get around to figuring it out I'll edit this post and script. I need to figure out why it gives the error "SIOCSIFFLAGS operation not permitted" when you disconnect and then try to reconnect again. But anyways, it works for now and connects you to WPA

[GregoireGentil]

Great tips! Many thanks. If you want to help one step beyond, you can try to patch /usr/bin/ai/networking/network_base.py. There is some WPA code there but it was not working and we didn't have time to fix it.

[ripper]

lol good to hear from you ... Ill take a look at it tomorrow, I'm one too many pints down for the night.

[ripper]

As I suspected, the problem with bringing the connection down and then back up again had to do with the version of dhcpcd installed on the touchbook. After installing dhcp-client instead everything works fine. I can connect to as many access points as I like without rebooting. Ill repost how to install this and the edited script later today. Also If I get time Ill see if I can edit the AI GUI to work along with this.

[ripper]

To make this work without having to reboot after the end of each connection do the following:

change to root

Code: Select all

sudo -s

update ipkg

Code: Select all

ipkg update

install dhcp-client

Code: Select all

ipkg install dhcp-client

create a new script file

Code: Select all

touch WPA_wifi.sh

make it executable

Code: Select all

chmod 700 WPA_wifi.sh

open your favorite editor

Code: Select all

vi WPA_wifi.sh

copy the following into the script

Code: Select all

#!/bin/sh
if [ $1 == "start" ]
then
        psk=`echo $3 | wpa_passphrase $2 |grep '\spsk='|cut -b 6-69`
        rmmod rt3070sta
        modprobe rt3070sta
        ifconfig ra0 up
        iwconfig ra0 essid $2
        iwpriv ra0 set AuthMode=WPAPSK
        iwpriv ra0 set EncrypType=TKIP
        iwpriv ra0 set WPAPSK=$psk
        dhclient ra0
elif [ $1 == "stop" ]
then
        dhclient -r ra0
else
        echo "USEAGE FOR WPA_WIFI.SH"
        echo "#### To start your connection: ####"
        echo "./wpa_wifi.sh start YOUR_AP_NAME YOUR_AP_PASSWORD"
        echo "#### To stop your connection: ####"
        echo "./wpa_wifi.sh stop"
fi


Now, If you are currently connected with my old script you must restart one last time.
Now in order to run the script make sure you are root if not already

Code: Select all

sudo -s

To connect to a network type the following

Code: Select all

./WPA_wifi start YOUR_AP_NAME YOUR_CLEARTXT_WPA_PASSWORD

To disconnect type the following

Code: Select all

./WPA_wifi stop

Hope this helps. Ill try to get around to editing the operating systems network GUI for next time.

** EDITED ... I had a typo in the stop portion of this script***

Nice work. Too bad this RT3070 driver only supports WPA-PSK, I'm using WPA-EAP so it looks like I'm going to be offline for a long time. I'd like to try to rt2x00 driver from the wireless-testing branch but I need the specific kernel header tree to be able to build that.

[GregoireGentil]

Kernel is published as well the rt3070 we are using. You are free to do any investigation you want! Read http://www.alwaysinnovating.com/wiki/index.php/Kernel.

[GregoireGentil]

We would love to see some patches for /usr/bin/ai/networking/network_base.py at least to support WPA-PSK. WPA-EAP will be much more complex.
