EAP-MD5 testing with radeapclient and eapol_test

Mon Sep 6 09:19:08 CEST 2010

Hi All,

I have a proxy setup ( proxy server 192.168.6.134) where users are proxied
to home server (192.168.7.40).
Host IP address = 192.168.6.181
FreeRADIUS  version 2.1.9

User authentication using radclient works fine when I issue following
command

echo "User-Name=raduser at mytest.com,Password=pass123" | radclient
192.168.6.134 auth testing123

I get following response on my proxy server

rad_recv: Access-Accept packet from host 192.168.7.40 port 1812, id=104,
length=68
Proxy-State = 0x3737
Framed-Protocol = PPP
Service-Type = Framed-User
Class = 0x52a505b1000001370001c0a8072801cb4d87ddbf246a0000000000000016

I try the same test to work out with EAP using following command:

echo "User-Name=raduser at mytest.com
,Password=pass123,EAP-Code=Response,EAP-Id=210,EAP-Type-Identity=
raduser at mytest.com" | radeapclient -x 192.168.6.134 auth testing123

I see following output on proxy server:

I have never succedded with eapol_test. I doubt on NAS-IP-Address attribute
in Access=Request which is 127.0.0.1.
Can some body point me where am I going wrong?
