MeshCommander 0.5.7 with latest NUC 7i5DNHE - wifi profiles problem

Hi!

I have just received the new NUC7i5DNHE, enabled AMT and started playing with MeshCommander. What I have quickly found is that on this platform it is not possible to add wireless profiles using MeshCommander (it fails silently), but it is possible to do so using default AMT web interface.

Since I have not found any other way of reporting the issue i am reporting it here.

Kind regards,

Chris

Hi,

Have rechecked this with new edition of MeshCommander (0.5.8) and the problem still remains.

Hi. Interesting. I will take a look at it. If I can't find the same problem, I will update MeshCommander to display more feedback so to help debug this.

Ylian,

I know what is the problem!!

1. SSID - by standard the max length is 32 chars. MeshCommander allows only 31. Plain AMT web allows full 32

2. Password - max length allowed is 63 characters. MeshCommander allows only 62. Plain AMT web allows full 63.

My guess is that the problem is ASCIIZ termination. It should be easy to fix.

 

Kind regards,

Chris

That is interesting! I just took a look and MeshCommander did not do any length validation on any of the WIFI profile fields. It just passed the strings as-is to Intel AMT. I just uploaded a new version of MeshCommander v0.5.9 that improves length validation. I did not bump up the version number, so you need to uninstall/download/install if you want to try it.

As for the 31/63 char issues. I don't see it on my computers. Try running MeshCommander like this:

    nw.exe -debug -wsmantrace

You will see all of the Intel AMT traffic. Try adding WIFI profile with a dummy user/ssid/pass and cut & paste the WSMAN call that fails over. I will take a look. It's possible this is a AMT issue, but I can to confirm. If you can also provide the exact Intel AMT version you are using, that would be great.

Thanks,
Ylian

Ylian,

This is what I have found. With the updated MeshCommander the problem is with SSID when it reaches 32 characters. Like below:

Wow, yes, looks like a firmware does not like 32 char long SSID's. Can you let me know the exact version of your Intel AMT? Also, if you have not done so already, try to update your BIOS/AMT to the latest version and try again.

Thanks,
Ylian

Ylian,

My AMT greets me with following version: v11.80.50. Bit more was actually visible from the log sent previously where I could read: "Server: Intel(R) Active Management Technology 11.8.50.3425".

BIOS is DNKBLi5v.86A.0035.2018.0111.1737 from 1/11/2018. (this BIOS version was actually withdrawn from the Intel website due to microcode patch instability). But, this is the latest BIOS which was available for NUC7i5DNHE.

Ylian, what is interesting in addition is that when AMT is accessed via original web pages (http://A.B.C.D:16992/wlan.htm) then it is possible to add 32 character SSID.

In addition I have re-checked with MeshCommander 0.6.0 - same issue with 32 character SSID.
