it seems like you are using EAP authenication, if you are a new bee to freeradius, i will suggest you to do PAP authentication first, because it is easier and state forword. EAP is a complex techniqe to authenticate the users. you can find simple tutorials on PAP authentication of freeradius. On Mon, May 27, 2013 at 9:54 AM, Elizabeth Fife <fifeeliz1@hotmail.com>wrote:
Hi All I am ready for an earbending likely from Alan but for the record I have read the debug and done as much searching as my brain can handle before this post
I am setting up free radius 2.2.0 on two Ubuntu Servers server12 (192.168.0.92) and server13 (192.168.0.93). So far I have installed latest freeradius version 2.2.0 on each server and added a test user in the file users: username = user1 password = secret
I have the added each machine as a client of the other for testing in clients.conf they both have the shared secret aaabbb
With the following testing command on server12 (192.168.0.92) ( echo "User-Name = \"user1\""; \ echo "Cleartext-Password = \"secret\""; \ echo "EAP-Code = Response"; \ echo "EAP-Id = 210"; \ echo "EAP-Type-Identity = \"user1\""; \ echo "Message-Authenticator = 0x00"; ) | \ radeapclient -x 192.168.0.93 auth aaabbb
I see on that same machine the following output Sending Access-Request packet to host 192.168.0.93 port 1812, id=125, length=0 User-Name = "user1" Cleartext-Password = "secret" EAP-Code = Response EAP-Id = 210 EAP-Type-Identity = 0x7573657231 Message-Authenticator = 0x00 EAP-Message = 0x02d2000a017573657231 Received Access-Challenge packet from host 192.168.0.93 port 1812, id=125, length=80 EAP-Message = 0x01d300160410b96bc21423da6e34055a25bd522be5f4 Message-Authenticator = 0x0881b25f760ebcfb4a9e2a6fc18ee4e1 State = 0x79e3295879302d94ae994e3671a52576 EAP-Id = 211 EAP-Code = Request EAP-Type-MD5-Challenge = 0x10b96bc21423da6e34055a25bd522be5f4 Sending Access-Request packet to host 192.168.0.93 port 1812, id=126, length=57 User-Name = "user1" Cleartext-Password = "secret" EAP-Code = Response EAP-Id = 211 Message-Authenticator = 0x00000000000000000000000000000000 EAP-Type-MD5-Challenge = 0x10a6ecf77fb2601ce855274efb4523b6d7 State = 0x79e3295879302d94ae994e3671a52576 EAP-Message = 0x02d300160410a6ecf77fb2601ce855274efb4523b6d7 rad_verify: Received packet from 192.168.0.93 with invalid Message-Authenticator! (Shared secret is incorrect.)
I have server13 (192.168.0.93) running in debug and its out put is below. It seems to end by successfully sending Sending Access-Accept of id 126 to 192.168.0.92 port 40535
Admittedly for some reason (?timing) there seems to be a duplicate rad_recv: Access-Request packet from host 192.168.0.92 port 40535, id=126, length=87 but it too is ultimately accepted Sending duplicate reply to client server12 port 40535 - ID: 126 Sending Access-Accept of id 126 to 192.168.0.92 port 40535
How do I reconcile this is it working or not
(Sub question why are there two requests?)
