How to catch the MSK (Master Session Key) from Wpa_supplicant?

[Douglas Diniz]

Hi... I have a problem. This is my setup:

(sorry for my english)

I have four computers. At the first computer I have the Freeradius server.
The second computer is connected to freeradius by ethernet, and this
computer has Hostap. The third computer is connected with hostap by wireless
and only pass through the packets to and from the fourth computer, where is
the wpa supplicant.
I'm using TTLS/MSCHAPv2 to authenticate, and everything is ok. After
authentication, the freeradius send the msk to hostap within the
access-accept. The problem is that i need to configure the wpa supplicant to
send the msk to the third computer, because the second and third computers
will use the msk in the next phase of my setup.
This is possible? Wpa supplicant can send the msk? If dont, there is another
supplicant that can do that?

Thanks
