<p>Dear all,<br>
<br>
I am trying to use FreeRadius 2.1.8 for AAA in a wimax network. The problem I am facing is that the WiMAX-MSK keys are not generated by FreeRadius. Can someone help me figure out what I am not doing OR doing incorrectly?<br>
<br>
I have configured the "raddb/sites-available/default" and "raddb/modules/wimax" files per instructions included in the files themselves. For reference, here are the configuration stanzas in the post-auth section of "default":<br>
<br>
<tt>update request {<br>
WiMAX-MN-NAI = "%{User-Name}"<br>
}</tt><br>
<tt>update reply {<br>
WiMAX-FA-RK-Key = 0x00<br>
WiMAX-MSK = "%{EAP-MSK}"<br>
}</tt><br>
<tt>wimax</tt><br>
<br>
Run-log from "radiusd -X" is also included at the end of this message. Here is the message that indicates that EAP is not computing MSK and EMSK:<br>
<tt>[wimax] No EAP-MSK or EAP-EMSK. Cannot create WiMAX keys.</tt><br>
<br>
Thank you in advance, and I apologize if this question has been answered before -- I did not find answers/pointers in the FAQ or the Wiki.<br>
<br>
Best Regards,<br>
Sumedh<br>
