Hi, I have installed Free Radius Client/Server. I just would like to use SIM Authentication. I have Modified the Conf file accordingly. Brought up the Radius server successfully and when I try to bring the client with command line arguments radeapclient -x localhost auth testing123 <eapsim-in.txt where the eapsim-in.txt there under tests/eapsim03 directory. Client sending the Message, but it is failed in the Server saying that no RAND attributes and cannot initiate sim authentication. Where client is receiving the Access Reject Message. Please guide me what format I have to use to initiate SIM Authentication. Here is the eapsim-in.txt file looks like: User-Name = "eapsim" NAS-IP-Address = marajade.sandelman.ottawa.on.ca EAP-Code = Response EAP-Type-Identity = "eapsim" Message-Authenticator = 0 NAS-Port = 0 EAP-Sim-Rand1 = 0xabcd1234abcd1234abcd1234abcd1234 EAP-Sim-Rand2 = 0xbcd1234abcd1234abcd1234abcd1234a EAP-Sim-Rand3 = 0xcd1234abcd1234abcd1234abcd1234ab EAP-Sim-Sres1 = 0x1234abcd EAP-Sim-Sres2 = 0x234abcd1 EAP-Sim-Sres3 = 0x34abcd12 EAP-Sim-KC1 = 0x0011223344556677 EAP-Sim-KC2 = 0x1021324354657687 EAP-Sim-KC3 = 0x30415263748596a7 Thanks & Regards Pramila ============================================================================================================================ Disclaimer: This message and the information contained herein is proprietary and confidential and subject to the Tech Mahindra policy statement, you may review the policy at <a href="http://www.techmahindra.com/Disclaimer.html">http://www.techmahindra.com/Disclaimer.html</a> externally and <a href="http://tim.techmahindra.com/Disclaimer.html">http://tim.techmahindra.com/Disclaimer.html</a> internally within Tech Mahindra. ============================================================================================================================
