Hi, 1. install ppp-2.4.3 2. I am attaching my radius.c where the radius client from pppd is sending the MAC address of connecting host. This is my patch and it works fine for me. I do NOT take any responsibility for the use of this changed file. The radius.c file has to be places into ppp-2.4.3/pppd/plugins/radius/ directory. When you open the file you will see a part like /* do you want to send MAC address or IP address in the attribute * Calling-Station-Id ? * SEND_HW_ADDR = 1 ( YES ) / 0 ( NO ) * string client_hw_addr contains clients MAC address */ where you can enable this option or not. This allows you to send the MAC address to the radius server ONLY if the authenticating host is on the same LAN segment as your gateway with pppd. It reads the MAC address from the arp cache! Recompile ppp-2.4.3 and voila ! I know this has NOT anything to do with freeRadius, but since the question was mailed here, maybe some other users may need this too.
