Configuration trouble (2.1.8 for use with WiMAX)

Wed May 12 22:00:17 CEST 2010

I have looked into BOC-WIMAX and it looks interesting but fairly incomplete.
I have not tried to get it working 100% so I have only a little experience.

Some of the NAS simply want to talk to FR via EAP-TTLS and receive only a
Framed-Filter-Id response.  Is there a manufacturer you are looking to work
with in particular or is this an attempt to get BOC-WiMax working as your
ASN?

David, thanks for your reply. I am using a simulated WIMAX ASN gateway from
the BOC-WiMAX distribution. It's available at:

http://opensource.bolloretelecom.eu/projects/boc-wimax/

Sounds like you have insights into keys that NAS equipment does not send to
FreeRadius. Can you share that information with me?

Best Regards,
Sumedh

Which product are you using? Some WiMax NAS do not send the proper keys to
Freeradius. I have gotten FR to work with pretty much all of the major
brands of WiMax we sell.

Subject: Configuration trouble (2.1.8 for use with WiMAX)

Dear all,

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?

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":

update request {
WiMAX-MN-NAI = "%{User-Name}"
}
update reply {
WiMAX-FA-RK-Key = 0x00
WiMAX-MSK = "%{EAP-MSK}"
}
wimax

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:
[wimax] No EAP-MSK or EAP-EMSK. Cannot create WiMAX keys.

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.

Best Regards,
Sumedh
