Hi all, I'm trying to make a test environment to authenticate users via EAP-SIM. I followed some freeradius documentation (freeradius-server-2.1.12/src/tests/eapsim-03) but when I start the radeapclient it just get stuck waiting for some FreeRadius server "response" The scenario is a FreeRadius listening on localhost interface and a radeapclient sending "Access-Requests" to that server. radeapclient -c3 -r1 -s -x 127.0.0.1 auth localhost-secret <eapsim-in.txt +++> About to send encoded packet: User-Name = "1232010000000000" NAS-IP-Address = 127.0.0.1 EAP-Code = Response EAP-Type-Identity = "1232010000000000" Message-Authenticator = 0x30 NAS-Port = 10 EAP-Sim-Rand1 = 0x30000000000000000000000000000000 EAP-Sim-SRES1 = 0x30112233 EAP-Sim-KC1 = 0x445566778899aabb EAP-Sim-Rand2 = 0x31000000000000000000000000000000 EAP-Sim-SRES2 = 0x31112233 EAP-Sim-KC2 = 0x445566778899aabb EAP-Sim-Rand3 = 0x32000000000000000000000000000000 EAP-Sim-SRES3 = 0x32112233 EAP-Sim-KC3 = 0x445566778899aabb radclient: no response from server It seems me that radeapclient is waiting for some freeradius server packet. I thought radeapclient was supposed to initiate the EAP-SIM authentication process, not the server. I'm running FreeRadius version: FreeRADIUS Version 2.1.8, for host i486-pc-linux-gnu, built on Jan 5 2010 at 02:49:11 And the FreeRadius server users configuration file is: 1232010000000000 Auth-Type := EAP, EAP-Type := SIM, EAP-Sim-Rand1=0x30000000000000000000000000000000, EAP-Sim-SRES1 = 0x30112233, EAP-Sim-KC1 = 0x445566778899AABB, EAP-Sim-Rand2 = 0x31000000000000000000000000000000, EAP-Sim-SRES2 = 0x31112233, EAP-Sim-KC2 = 0x445566778899AABB, EAP-Sim-Rand3 = 0x32000000000000000000000000000000, EAP-Sim-SRES3 = 0x32112233, EAP-Sim-KC3 = 0x445566778899AABB All attributes are on the same line. I included the eap { } On the eap.conf file Any help would be appreciated!!! Thanks ... -- Ronaldo Afonso www.vexcorp.com +55 11 4932-5971 ronaldo.afonso@vexcorp.com
