Fragmented EAP frames was My problem with PEAP
Hmm,
My other message did not make it through. Perhaps people are sick
of hearing about this :)
I grabbed the latest snapshot on friday. Recompiled. Reconfigured the
default radiusd.conf file to use eap/peap.
I am still seeing fragmented Access Challenge packets. However the
first access challenge was not fragmented. The ones after that were.
My config, dumps and debug are included.
radtest works with the unchanged default radiusd.conf returning stuff from the
users file.
Sending Access-Request of id 123 to 127.0.0.1:1812
User-Name = "wer"
User-Password = "testtest"
NAS-IP-Address = hotspot
NAS-Port = 1
rad_recv: Access-Accept packet from host 127.0.0.1:1812, id=123, length=37
User-Name = "wer"
Framed-IP-Address = xxx.xxx.xxx.31
Framed-IP-Netmask = 255.255.255.255

Edit 1 to radiusd.conf: PEAP
Upon enabling peap (and thusly tls), radtest still works, but I get an access
reject when attempting to use peap.
I had to configure tls right? I used my certs. I changed the default type for
eap to peap and the default type for peap to mschapv2
At one point I added copy_request_to_tunnel to peap {} because I think I
misinterpreted the debug below. I think that change was moot though.
I am back to a similar fragmented frame problem as well though I think the
conversation made it further.
The first access challenge is not fragmented. However the second challenge is
severely fragmented
The supplicant says attempting to "authenticate the user" instead of just
"validating user". So I think the the supplicant is responding to the challenge
now with another request.
However the next challenge is severely fragmented.
I am suspect of these lines, which is why at one point I tried the
copy_request_to_tunnel (radiusd.conf Edit 2) but realized it probably didn't
matter at this point (radiusd.conf Edit 3).

Re: My problem with PEAP
Hey guys,
I reconfigured from the default radiusd.conf file and did this test again
with the same strange results from peap. I could certainly be doing something
stupid and would appreciate any further feedback. I have included my
radiusd.conf file and a new tcpdump from the server.
Sorry for the attachments.
Best wishes,

I've looked at your packet trace, and there are two EAP packets (and
therefore PEAP packets) in the Access-Challenge.
I've never seen this before, so I suspect it's a local configuration
issue. Still, the server should be fixed to NOT do this.
From the debug output, it looks like you've managed to make the
server call the EAP module *twice* for the request, during the
"authenticate" stage. I have no clue how you managed to do this, but
it's definitely wrong.
What did you edit in the server configuration to make it do this?
Under normal circumstances, PEAP should work "out of the box", by
simple configuring the peap{} module section, and starting the server.

From what I have read about EAP, and from my discussions with others on this list, I believe I am seeing a problem from freeradius. Please correct me if I am wrong. According to the documentation in ./doc/rlm_eap. The client is not responding to step 6 "Access Challenge" from the radius server. I can see the Radius packet making it to the client. The only thing I can find that is odd about the challenge is that there are two eap portions of the frame. My hope is that the client is ignoring the frame because of this. Since there is no response from the client(supplicant) I do not get an EAP-Success/EAP-failure and begin to negotiate any ssl/wep stuff. So I don't even think I am verifying the server using the installed CERT at this point. In other words, I don't suspect I have a key/cert problem yet :). I have included the frames in this email. They were captured on the radius server side. Note there are two separate attempts from the client to authenticate itself. I am questioning either of the Access Challenge frames. I would love it if someone could look at these frames and tell me if they are correct (that freeradius is creating them properly). Below the message Authenticator is similar to 0x00. In the frame sent to the supplicant, the second portion EAP type 79 does not have the authenticator, the first portion EAP type 79 does have the Message Authenticator and is filled with a value other then 0x0. I am guessing that is where the hash for the password goes. Any help would be greatly appreciated.

My problem with PEAP
Hey everyone, I continue to have a problem using peap with freeradius-snapshot-20031110. From what I have read about EAP, and from my discussions with others on this list, I believe I am seeing a problem from freeradius. Please correct me if I am wrong. According to the documentation in ./doc/rlm_eap. The client is not responding to step 6 "Access Challenge" from the radius server. I can see the Radius packet making it to the client. The only thing I can find that is odd about the challenge is that there are two eap portions of the frame. My hope is that the client is ignoring the frame because of this. Since there is no response from the client(supplicant) I do not get an EAP-Success/EAP-failure and begin to negotiate any ssl/wep stuff. So I don't even think I am verifying the server using the installed CERT at this point. In other words, I don't suspect I have a key/cert problem yet :). I have included the frames in this email. They were captured on the radius server side. Note there are two separate attempts from the client to authenticate itself. I am questioning either of the Access Challenge frames. I would love it if someone could look at these frames and tell me if they are correct (that freeradius is creating them properly). Below the message Authenticator is similar to 0x00. In the frame sent to the supplicant, the second portion EAP type 79 does not have the authenticator, the first portion EAP type 79 does have the Message Authenticator and is filled with a value other then 0x0. I am guessing that is where the hash for the password goes. Any help would be greatly appreciated.
