wpa_supplicant testing

Wed Dec 27 18:56:13 PST 2006

Thanks Ambedkar,
	As for some clarification of point 2 below, where can I read more about the 5 configurations that you have listed below? Like you mentioned in point 3 below about some parameters (like key_mgmt), can I get a document where I get to read about these parameters (along with their description)? I have already gone through the sample configurations. I want to try some more combinations of configurations. I want a manual which explains each parameter and the situation in which I should be defined so that I can make my own sample configurations.

Regards,

Hi Bhuvan,
?
1.To Develop test case: You should read the specifications such as design spec, functional spec or implementation spec which released to setup the test scenario. You ask your developer for those specs, without spec reading specs you can't understand its functionality and other stuff.
?
2.To make conf files: There are many types which you can use it for your Station(Client) configuration,(1)Plain-text(2)Static WEP (3)WPA/WPA2 PSK (4)IEEE802.1X with Dynamic WEP keys (5) WPA/WPA2 Enterprise.
???? Item number (4) and (5) which will use External/Internal authetication server.Internal authentication server means,server will be integarted on the AP.
??? External server means,we have to?use the FreeRADIUS or whichever available in the market.
?
3.Sample conf:
?key_mgmt is for plain-text "NONE",WPA-PSK "WPA-PSK" and WPA Enterprise "WPA-EAP"
?"wep_key0" and "wep_key1",you can configure different keys for?stations access,For example in CISCO AP,DEVICESCAPE AP and Broadcom AP?you can configure 4 different wep keys.
? "wep_keyidx=0",if you configure in station the first key(wep_key0) will be used to associate with AP.
?
4.Example conf,
?
ap_scan=2
network={
ssid="WEP_TEST"
key_mgmt=NONE
wep_key0=1234567890
wep_key1=1222222222
wep_tx_keyidx=0
auth_alg=OPEN
}
?
?
WPA-PSK
?
ap_scan=2
network={
ssid="chennai"
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk="12345678"
scan_ssid=1
}

I am doing a project which deals with porting the wpa_supplicant code to
nucleus RTOS. Our job is to develop test scenarios to test the
authentication procedure and the ported supplicant code. Can anyone
provide me some inputs on how to proceed with this testing? I am new to
WLAN world however I'm aware of the WLAN terminology and technology by
now.

Please guide me on the following:
1. Developing Test Cases
2. How exactly do I make permutations and combinations for making more
.config files (wpa_supplicant configuration file)?
3. There are some sample configurations available. I am not able to
understand what the various parameters
(key_mgmt,wep_key0,wep_key1,wep_tx_keyidx etc..) mean. Is there any
documentation which can help me?
4. Does wpa_supplicant support ad-hoc mode operations and if yes what is
the limit to the maximum no. of devices which can be present in an
ad-hoc scenario?
