Hello
I am very new to freeradius and I'm trying to set up a freeradius server. I want it to use MAC addresses for client authentication. I would like to know if it is possible to test the setup on an Ethernet network instead of a wireless network. I have not read anywhere if it is possible to do this but this is what I have available at the moment. The FreeRADIUS is running on FreeBSD 4.10 using a Cisco C3550 switch as its authenticator. The client is running Windows XP Professional. Initially, I tried to test it with a username/password method with MD5 authentication type with:
users: testuser Auth-Type := EAP, User-Password == “password”
clients.conf:
clients 10.250.0.3 { //Switch IP address
secret = secretpass
shortname = switch
nastype = ciscoon WinXP client: EAP-Type = MD5-Challenge
This worked without any problems. --------------- I moved on to test with MAC authentication method. users: 0007e9-e9a6e4 Auth-Type:=Local, User-Password == “password” //client MAC 000e84-8e9700 Auth-Type:=Local, User-Password == “ password” //switch MAC
I’ve also tried:
0007e9-e9a6e4 Auth-Type:=Local, User-Password == “0007e9-e9a6e4” 000e84-8e9700 Auth-Type:=Local, User-Password == “0007e9-e9a6e4”
Other combinations I’ve tried with the MAC are: w/o dashes, all caps, using colons.
For Auth-Types, I have also tried using EAP and LEAP
clients.conf file remained the same
I added under ‘modules’ section:
----
peap {
default_eap_type = mschapv2
}mschapv2 {
}
----
under ‘eap’ I added:
default_eap_type = PEAPOn the client side, I changed: EAP-Type = Protected EAP(PEAP)

What is it that I am doing wrong and/or what do I need to include? Radius rejects when I use PEAP. I have also tried using EAP and LEAP using the same procedure. EAP gives me access-challenge. When radius finds LEAP, it says it successfully initializes but then it also gives access-challenge. Can someone give me some feedback on what else I need to do?
Thanks alot Robert
