WL1807MOD: WFA - SAE-5_9_1 Ping test case Failed:

Hi,

not very clear. I can see on the terminal CLI that the station is able to connect but seems like it cannot get an IP address.
There is no sniffer to show the connection, only a sniffer for the station testbed.

Hi Shlomi,

When I issue the below command from the putty console , I don’t see the IP is getting assigned by the router.
sta_set_ip_config,interface,wlan0,dhcp,1,type,1

We don’t have the dhcp package, we have only dhcpd. I have updated the details same in the ticket.

Hi,

But it is not the dhcp command that needs to be run.

dhcp is just an argument of the command that it is processing.

And the above does seem as it is applied with no error.

If I take as an example another test that used this command (with different parameters), I see also a good response:

Hi Shlomi,

   I was able to reproduce the no such file or directory issue. This issue happens only on the first time dont know know why?

Actually, it is the link in S40.

Hi Shlomi,
From the share console putty log, we can see that the ip address is not assigned to the wlan0 interface.

uccl log i could see the ip address is not passed. How the DUT will get the ip address?

Hi Shlomi,

Hi,

seems like the 1st step of recording the GTK and IGTK is OK when comparing to the supplicant log. Then, connection is succeeded but I do not see DHCP request from the device. This is why PING fails. you can always set is statically on the platform CLI just for the test (e.g. ifconfig wlan0 x.x.x.x). 

Can you double check that you do not get an IP address by typing ifconfig and see?

Regards,

Shlomi

Please share me the dhcp bin file to get the ip address? we dont have dhcp package.

root@s40-bigbend-v1:/lcc/data/test_engine# dhcpc

-sh: dhcpc: command not found
root@s40-bigbend-v1:/lcc/data/test_engine# dhcp
dhcp_release dhcpcd
root@s40-bigbend-v1:/lcc/data/test_engine# dhcp

Viswa

Hi,

I am almost sure we use udhcpc but let me double check.

Shlomi

Hi Shlomi,
   Please let me know whether you want us to make changes and retest it.

Viswa

Hi,

I shared this topic over Email with ways to set the static IP.

We also do not use DHCP since it is not implemented in the agent.

In parallel, I am trying to see if we can add it to the agent.

So you can proceed with setting the expected IP address in systemd and test.

Hi Shlomi,
 We have shared the log from the reference unit.

Hi Shlomi,

  From the testing team has asked to look at the M3 packet of the eapol to get the IGT_key.

I could not decrypt the wpa_key_data to check for the IGT_KEY_data?

Please let me know how to decrypt ?

Regards,

Viswa
  

Hi,

This is a WPA3 connection so it is a little more complicated.

You can look at the supplicant log and fetch the PMK.

Then in Wireshark, go to where you add the keys and add it.

You should start seeing the decryption data but for some reason it does not always show the decryption of the EAPOL M3.
