hi everybody,, I am trying to learn and test EAP. So i started with simple md5. I have defined packets in a file. like following. User-Name=bob Cleartext-Password=hello EAP-Code = Response EAP-Id = 210 EAP-Type-Identity = bob Message-Authenticator = 0x00 and it is repeated around 100 times (to make 100 eap packets). Now I issued the following command to send packets to server. radeapclient -x -f eap.txt 192.168.0.112 auth testing123 ,Now i am facing a major problem, around first 5 to 6 requests are entertained normally, and access-accept is returned. But after some requests a strange behavior is found. When client sends its request to server, a message is shown (rlm_eap: EAP-Message not found), And Access-Reject packet is received from server. But after this the client keep sending Access-Requets (which are actually the response of the challenge) to the server. could you please tell me whts the probelm. Here is some debug output. Received Access-Accept packet from host 192.168.0.112 port 1812, id=131, length=49 EAP-Message = 0x03d30004 Message-Authenticator = 0x34208362152e1e801e6547a2a453764f User-Name = "bob" EAP-Id = 211 EAP-Code = Success Sending Access-Request packet to host 192.168.0.112 port 1812, id=132, length=85 User-Name = "bob" Cleartext-Password = "hello" EAP-Code = Response EAP-Id = 210 rlm_eap: EAP-Message not found Received Access-Reject packet from host 192.168.0.112 port 1812, id=132, length=20 Sending Access-Request packet to host 192.168.0.112 port 1812, id=133, length=25 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00 User-Name = "bob" Cleartext-Password = "hello" EAP-Code = Response EAP-Id = 210 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00 EAP-Message = 0x02d2000801626f62 Sending Access-Request packet to host 192.168.0.112 port 1812, id=133, length=71 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "bob" Cleartext-Password = "hello" EAP-Code = Response EAP-Id = 210 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 EAP-Message = 0x02d2000801626f62 Sending Access-Request packet to host 192.168.0.112 port 1812, id=133, length=71 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "bob" Cleartext-Password = "hello" EAP-Code = Response EAP-Id = 210 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 EAP-Message = 0x02d2000801626f62 Sending Access-Request packet to host 192.168.0.112 port 1812, id=133, length=71 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "bob" Cleartext-Password = "hello" EAP-Code = Response EAP-Id = 210 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 EAP-Message = 0x02d2000801626f62 Sending Access-Request packet to host 192.168.0.112 port 1812, id=133, length=71 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "bob" Cleartext-Password = "hello" EAP-Code = Response EAP-Id = 210 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 EAP-Message = 0x02d2000801626f62 Sending Access-Request packet to host 192.168.0.112 port 1812, id=133, length=71 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "bob" Cleartext-Password = "hello" EAP-Code = Response EAP-Id = 210 EAP-Type-Identity = 0x626f62 Message-Authenticator = 0x00000000000000000000000000000000 EAP-Message = 0x02d2000801626f62 Thanks in advance
