Steve, Your wireless access point is sending the MAC address as the username and password. Change the username and password in the users file and the authentication will work. rad_recv: Access-Request packet from host 10.10.18.241:2160, id=7, length=53 User-Name = "00215c-08b25d" <--- This came from the wireless access point User-Password = "00215c-08b25d" <--- This came from the wireless access point Tim From: freeradius-users-bounces+tim.sylvester=networkradius.com@lists.freeradius.org [mailto:freeradius-users-bounces+tim.sylvester=networkradius.com@lists.freeradius.org] On Behalf Of Steve Wu Sent: Friday, May 08, 2009 8:35 AM To: freeradius-users@lists.freeradius.org Subject: FR Using MAC Authentication Hi - I have just started tinkering with Freeradius, I built an Ubuntu 8.10 server box and installed FR --> sudo apt-get install freeradius*. It installed in a breeze and tested fine. I have setup a HP420 AP for testing, it's chattering with the FR box fine (I think). I want my wireless clients to do MAC authentication via the FR box. I have setup my users file to auth two of my test laptops: 000E35-84610A Auth-Type := Local, User-Password == "esradius" 00215C-08B25D Auth-Type := Local, User-Password == "esradius" When either tries to connect up, in the FR debug I see: rad_recv: Access-Request packet from host 10.10.18.241:2160, id=7, length=53 User-Name = "00215c-08b25d" User-Password = "00215c-08b25d" Processing the authorize section of radiusd.conf The authentication eventually fails: rlm_pap: WARNING! No "known good" password found for the user. Authentication may fail because of this. Why is the User-Password the MAC address and not what is specified in the users file? I have only tweaked the users and clients.conf files. Just simple MAC authentication, that's all I want at this point. Thanks in advance! - Steve
